External table is not in the expected format thrown only in certain situations

<p>I am trying to open an xlsx file and I get the External table is not in the expected format only when I open from a certain area of my app. So it works just fine if I call it from 1 area, but then I do the same thing from a different part of the app, calling the same code block, and it throws that exception. Same code block. Same excel file.</p>

Unable to change anchor.text

how to install and use Code Contracts?
|
<p>I have a basic question, might be it is so obvious but for some reason i can't seem to be successful with installing and using Code Contracts.</p>
<p>I've downloaded the package from MSDN, installed it following the online documentation but i still get an IDE warning for the below code statement:</p>
<p><code>Contract.Requires(inputParameter != "");</code></p>
<p>the IDE warning is:</p>
<p><em>"Method invocation is skipped. Compiler will not generate method invocation because the method is conditional, or it is partial method without implementation"</em></p>
<p>Anything I'm missing in the process of enabling Code Contracts? I'm using VS2010 Ultimate SP1</p>

Google Maps outside of Activity
|
<p>I have been playing with Google Maps V2 for a few weeks now. I tinker more than anything and when I have an App/Game that I enjoy I like to learn how they work. I have recently been playing Ingress which got me into playing with how Maps can be interacted with and used.</p>
<p>One thing I cannot figure out is how to use Google Maps outside of an Activity. There has to be some sort of game loop but I don't know how this would work inside of an Activity or how to use Google Maps outside of one due to some of the methods that are required to get a user's location.</p>
<p>Answers or being pointed in the right direction would be appreciated.</p>

how to get around UnboundLocalError?
|
<p>I just started programming and tried to write something but (of course) it failed. After I while I got to the real problem: The <code>UnboundLocalError</code>. So to save you from all the rubble around I stripped the code down to this:</p>
<pre><code>def test():
try:
i1 = int(i1)
i2 = int(i2)
except ValueError:
print "you failed in typing a number"
def input():
i1 = raw_input('please type a number \n >')
i2 = raw_input('please type a number \n >')
</code></pre>
<p>Then I wrote down:</p>
<pre><code>>>>input()
please insert a number
> 3
please insert a number
> 2
>>>test()
</code></pre>
<p>And then I got:</p>
<pre><code>that was not a number
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 7, in test
UnboundLocalError: local variable 'i1' referenced before assignment
</code></pre>
<p>How can I solve this in a Pythonic way? Or should I take a whole different way?</p>

Android WebView, how to handle redirects in app instead of opening a browser
|
<p>So right now in my app the URL I'm accessing has a redirect, and when this happens the WebView will open a new browser, instead of staying in my app. Is there a way I can change the settings so the View will redirect to the URL like normal, but stay in my app instead of opening a new browser?</p>
<p>Edit:</p>
<p>I want the redirecting URL, I just don't know how to create it, so the only way to get to that URL is through one that will cause a redirect to the one I want. </p>
<p>For example: When you go here: <a href="http://www.amazon.com/gp/aw/s/ref=is_box_/k=9780735622777">http://www.amazon.com/gp/aw/s/ref=is_box_/k=9780735622777</a> notice how it will redirect the URL to the actual product. In my app, if I open it in a new browser, it will do that just fine, however if I keep it in my app with a WebView, it will show up as though it's doing a search for k=9780735622777, like this: <a href="http://www.amazon.com/gp/aw/s/ref=is_s_?k=k%3D9780735622777&x=0&y=0">http://www.amazon.com/gp/aw/s/ref=is_s_?k=k%3D9780735622777&x=0&y=0</a> . OR, it will open the view in the browser and show what is appropriate. However, I want to keep everything in my app.</p>

That is my current Coce:</p>

jQuery('.single_content').hide();
jQuery('.css_hide').show();
jQuery('.show_content').click(function(){

Control scrolling DIV with keyboard
|
<p>I have a div that contains a table that has many rows in it. The scrollbar displays correctly and works correctly when using the mouse. However, in an effort to make it keyboard driven I have made the div have focus and then being able to use the arrow keys (via a onKeyPress event I am able to move up and down the div. </p>
<p>This works except for a little quirk... When the div gains focus and I press the down arrow key, the scrollbar also moves down (effectively hiding the row I'm now currently focused on). So my question is, is there any way to avoid this from happening?</p>
<p>I was looking at the following commands: doScroll(), or scrollTo(), or scroll()</p>
<p>Would any of those work or is there something else I could do to correct the behavior of the scroll bar?</p>

Caching the return results of a function from John Resig's Learning Advanced JavaScript
|
<p>I have a few questions about this function from John Resig's exercise #19 in <a href="http://ejohn.org/apps/learn/#19" rel="nofollow">http://ejohn.org/apps/learn/#19</a></p>
<ol>
<li><p>what is the purpose of the second last line <code>getElements.cache = {};</code> Is it storing <code>return results</code> in an array? </p></li>
<li><p>If my guess in (1) is correct, is it only catching <code>return results</code> because, in the "else" section of the function, <code>getElements.cache[name] = results;</code>?</p></li>
<li><p>when I played with the code in the console in the tutorial, I removed the line <code>getElements.cache[name] = results</code> from the "else" section, but still got the same result, as when it was there--namely, it told me that there were 76 elements. What, therefore, is the purpose of this line <code>getElements.cache[name] = results</code> if it`s not necessary to get the result?</p></li>
<li><p>is there any significance to the fact that, in the "else" section of the function, the order of the line <code>getElements.cache[name] = results;</code> is reversed from the <code>if</code> section of the code, where it says <code>results = getElements.cache[name]</code></p></li>
<li><p>finally, is <code>cache</code> a pre-defined function in JavaScript? I can't find it in the documentation. </p></li>
</ol>
<pre><code>function getElements( name ) {
var results;
if ( getElements.cache[name] ) {
results = getElements.cache[name];
} else {
results = document.getElementsByTagName(name);
getElements.cache[name] = results;
}
return results;
}
getElements.cache = {};

Exposing Member Functions in a Custom Class through WCF
|
<p>I have some member functions in three custom classes already created in my service. My objective is to use these custom classes on the client side to access the the member fuctions in the service. How do I expose these classes with all the member methods in them to the client?</p>
<p>I created these three classes in my service and marked them as "DataContract", and the member fuctions as "OperationContract". I created an Interface that defines these custom classes as OperationContracts returning an object of each of the classes through implementing them on a separate class.</p>
<p>Unfortunately, I couldn't achieve my objective because two of the classes have a contructor that takes some parameters, whereas the class with no contructor was accessible on the cliet side but I couldn't see the member methods in the class.</p>
<p>please I need your hints on what to do. Thank you.</p>

How to get notified when "Add account " Activity has finished
|
<p>I'm developing an application that uses google push c2dm.
When I start my application I check to see whatever the phone has a Google account registered or not.
If there is no account I use startActivity to start the "Add account" activity</p>
<pre><code>Intent addAccountIntent = new Intent(android.provider.Settings.ACTION_ADD_ACCOUNT).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(addAccountIntent); </code></pre>
<p>Is there a way to get notified when this activity has finished, so that I can confirm that there is a Google account active on the phone.</p>

Flight board effect using jquery
|
<p>I am trying to build a flight board effect using jquery.</p>
<p>So far i have been able to create an effect that rotates characters. Here's what I have achieved so far: <a href="http://www.jaspreetkaur.com/chatter/" rel="nofollow">http://www.jaspreetkaur.com/chatter/</a></p>
<p>See the text "get to the chatter that matters"</p>
<p>However O do not feel this effect is realistic. I want the text flip to be like <a href="http://nolanow.cacno.org/" rel="nofollow">http://nolanow.cacno.org/</a> (see the word NOW in logo) This effect is created with help of images.</p>
<p>I do not want to use images to keep the effect reusable, so how can i create the effect without use of images?</p>

Trying to delete files after concatenation with java

<p>here is a code to concatenate all files from a folder.

Global pointer to object causes access violation?
|
<p>Maybe you will be able to clear something for me, because I don't know exactly where my thinking is flawed. First some code:</p>
<p>Talker.h: </p>
<pre><code>class talker
{
public:
talker();
void sayHello() {cout << "Hello";} ;
};
</code></pre>
<p>anotherClass.h:</p>
<pre><code>class anotherClass
{
public:
anotherClass();
void doSomethingYourself() { cout << "will do"; };
void askHimToSayHello() { pointerToTalker->sayHello; };
//Access violation, bad pointer(?)
};
</code></pre>
<p>common.h:</p>
<pre><code> static talker *pointerToTalker;
// if I add here "= new talker", code works fine
</code></pre>
<p>main.cpp:</p>
<pre><code>#include "common.h"
int main()
{
pointerToTalker = new talker; // Here is the bug, but why?
pointerToTalker -> sayHello; // says Hello alright
anotherClass *pointerToAnotherClass = new anotherClass;
pointerToAnotherClass -> doSomething (); //Does something OK
pointerToAnotherClass -> askHimToSayHello(); // Causes access violation
}
</code></pre>
<p>Of course functions are a bit more complex, and each is implemeted in coresponding .cpp including "common.h". My question is - why pointerToTalker, if initialized inside main() does not work inside anotherClass::AskHimToSayHello()? It should pointing to valid memory by the time it is used there.
It is my "Hello world, OOP!" btw, so please be gentle if there is no hope for me :)</p>
<p>Sorry for the childish style btw. It helps me cut down the code I have to something more compact without me loosing the big picture :).</p>

Extracting Geometry from IFC File
|
<p>I have to extract the geometry of a ifc file in JAVA. My problem is, that i don't know how to do it.</p>
<p>I tried to use <a href="http://www.openifctools.org/" rel="nofollow">openifctools</a> but the documentation is really bad. For now i have the ifc file loaded, but i cannot get the geometry out of the model. </p>
<p>Does anyone have experience with ifc model loading?</p>
<p>Thanks in advance.</p>
<p>EDIT: This is what I've done so far</p>
<pre><code>try {
IfcModel ifcModel = new IfcModel();
ifcModel.readStepFile(new File("my-project.ifc"));
Collection<IfcClass> ifcObjects = ifcModel.getIfcObjects();
System.out.println(ifcObjects.iterator().next());
} catch (Exception e) {
e.printStackTrace();
}
</code></pre>
<p>This correctly loads the ifc file. But I don't know what to do with this information. </p>
<p>I also tried to use <a href="http://ifcopenshell.org/index.html" rel="nofollow">IfcOpenShell</a> but the provided jar container hadn't worked either. At the moment I try to build IfcOpenShell by myself.</p>
<p>I'm kinda desperate because everything is very undocumented and I really need to load and parse the ifc geometry.</p>

Image.FromFile starts 'skipping' files
|
<p>I'm loading a bunch of files into a <code>ListView</code>, and I use <code>Image.FromFile()</code> and <code>.Width</code> and <code>.Height</code> to display the the resolution of each file in a designated column. However, whenever I load more than a handful of files, this method starts skipping files. The first, say 50 files are all loaded properly but after that more and more files are skipped.</p>
<p>What could cause this problem, and are any better alternative methods available? This method also slows down the loading process considerably, so hopefully this process can be sped up a little bit.</p>
<p>EDIT: Sorry... Here's the relevant code:</p>
<pre><code>private void AddItem(string file)
{
FileInfo fi = new FileInfo(file);
ListViewItem item = new ListViewItem(fi.FullName);
try
{
Image img = Image.FromFile(fi.FullName);
item.SubItems.Add(string.Format("{0} x {1}", img.Width, img.Height));
}
catch { }
((ListView)sender).Items.Add(item);
</code></pre>
<p>}</p>
<p>The try/catch methods are meant to prevent errors for non-image files. However, they also seem to be 'responsible' for the skipping issue. When I disable them I get an 'out of memory' error, which seems to be the real cause here.</p>

better writing style for the following code
|
<p>I was wondering if someone could tell me the pythonic way to check out the following.</p>
<p>I have a 6 bit binary number and want to check with its decimal values. Using mathematical function is one way but still it would require that I write around 2**6 if constructs.</p>
<p>So I wanted to know if there's an easier statement to write it. </p>
<p>Also assume that lets say it's not binary then what's the better way to check for 2**6 values in python.</p>
<pre><code>if(a==1):
....
else:
if(a==2)
.....
</code></pre>
<p>One way is saving it in a list and checking it with the indexes but still that would require that many if-else I guess.....</p>

saving button state in jquery
|
<p>I am using a few custom jquery buttons with <code>datatables</code> to do some sorting. Unfortunately when I leave the page and come back, <code>datatables</code> remembers its state, but the toggle button doesnt. So I am trying to set a cookie when the button is toggled so I can read it later, but I cant seem to get it working.</p>
<p>Here is my button code with the cookie creation:</p>
<pre><code>$('#completed_button').bind('change', function(){
if($(this).is(':checked')){
$(this).button('option', 'label', 'Hide Completed');
oTable.fnFilter('Completed',6,false);
$.cookie('showCompletedState', 'checked');
} else {
$(this).button('option', 'label', 'Show Completed');
oTable.fnFilter('',6,false);
$.cookie('showCompletedState', 'unchecked');
}
});
</code></pre>
<p>Now here is my attempt at reading the cookie and setting the button state:</p>
<pre><code>var showCompletedState = $.cookie('showCompletedState');
if (showCompletedState == 'checked') {
<-- need something here to actually change button state -->
$('#completed_button').button('option', 'label', 'Hide Completed');
oTable.fnFilter('Completed',6,false);
} else if (showCompletedState == 'unchecked') {
<-- need something here to actually change button state -->
$('#completed_button').button('option', 'label', 'Show Completed');
oTable.fnFilter('',6,false);
}
</code></pre>

What is the correct way of stopping an object in a method that was created in another?

<p>I have a form that has a button which creates a new object and calls it's <code>start()</code> method.</p>
<p>The program works fine, however, I now want to create a stop button. I obviously cannot call the object's <code>stop()</code> method as it is elsewhere, but, I just can't think of the correct way of changing my code.</p>
<p>As I write this, the best thing I can think of is to take the <code>MyObject myo = new MyObject("test");</code> and place <code>MyObject myo;</code> at the top of the class, outside methods and then try to set it from within the class.</p>

Alarm doesn't ring if program force-stopped
|
<p>I have an alarm app which I think was programmed in the standard way using an <code>AlarmManager</code> and <code>BroadcastReceiver</code>. I have even added code so that the alarm stays active after a reboot. I have been using the program without problem for weeks now.</p>
<p>I had been led to believe that doing things this way meant that it was not essential to keep my alarm program running the whole time, but to my horror I have just found that if I set an alarm and then do a force stop of my alarm app, then the alarm never rings.</p>
<p>I'm not sure that this means I made a mistake in my coding, or I was misled into believing that it is possible to keep the alarm set despite the app being stopped.</p>
<p>Maybe the OS somehow detects that my alarm app has an alarm running and therefore avoids shutting it down? So as long as the user doesn't <em>manually</em> do a force stop then all should be well.</p>
<p>Any ideas?</p>
<p><strong>EDIT:</strong> I just tested "Alarm Clock Xtreme". I set an alarm. Then did a force stop... the alarm never rang. </p>

Best way to convert int[][] to int**?
|
<p>This is kind of a curiosity question. I do have an existing solution, but I wonder if people know of a better approach.</p>
<p>My callers want to call me with int[][]. I have a routine that needs to process an int**. What's the best way to do this conversion? In other words:</p>
<pre><code>public static void Func1(int[][] data) {
Func2(data); //how to do this?
}
private unsafe static void Func2(int** data) {
//process data
}
</code></pre>
<p>Following is the best approach I could come up with. It works fine, but I can't say I'm 100% happy with the recursive approach (and the O(data.Length) stack space it requires)</p>
<pre><code>public static void Main() {
var test=new[] {
new [] {10},
new [] {20,30},
new [] {40,50,60},
new [] {70,80,90,100},
};
MySolution_Func1(test);
}
public unsafe static void MySolution_Func1(int[][] data) {
var items=new int*[data.Length];
Recurse(0, data, items);
}
public unsafe static void Recurse(int index, int[][] data, int*[] build) {
if(index==data.Length) {
fixed(int** finalp=build) {
Func2(finalp);
}
} else {
fixed(int* nextp=data[index]) {
build[index]=nextp;
Recurse(index+1, data, build);
}
}
}
private unsafe static void Func2(int** data) {
for(var j=0; j<4; ++j) {
for(var i=0; i<j+1; ++i) {
Debug.WriteLine("{0},{1}: {2}", j, i, data[j][i]);

Get and set specific height of elements
|
<p>I'm a little bit new to JavaScript, but I hope someone can help me.</p>
<p>How can I get the height of a paragraph element or div? By height I don't mean how high it is, but how many pixels it is sitting from the very top of the page. Is there any way to get this value?</p>
<p>And to the 2nd part of my question: how can I set this specific value to another element?</p>
<p>Thank you!</p>

how to delete objects?
|
<p>I have two classes:</p>
<pre><code>Class Node {
int address
}
Class Link{
int latency;
int bandwidth;
Node node1;
Node node2;
}
public Link [] link= new Link[Nmax];
</code></pre>
<p>if I want to create a link between two nodes, it is easy, I've just to:</p>
<pre><code>node1=new Node(); //and then I add parameter like address and so on
node2= new Node();//...............
link[1]= new Link();
link[1].node1=node1;
link[1].node2=node2;
link[1].latency=15; //and so on, we suppose that we have 100 nodes and 60 links
</code></pre>
<p>Now, during the program, sometimes we add some new nodes then we have to add links between them, I can do this with the same manner us above, my question is:
what I have to do if I want to delete a node ? (links between this node and other existing nodes must be deleted too)</p>

submitting forms
|
<p>I was wondering if some one disables javascript how will my form be submitted for checking with Php. One more thing I would like to know how can I perform something like this if the person clicks the submit button and PHP checks a few fields if one of the fields is not valid I return an error in a div and if there is no error the script runs. I know how to perform the jquery ajax, mysql and stuff but submitting data if javascript is disabled is a bit confusing for me. I mean I wont be providing any form action so how will this all work. I hope I made some sense, Thanks.</p>
<p>// edited</p>
<p>Ok I got a few answers thanks it helped me understand how this all works. My final addition to the question is if I submit a form with no action it will be like submitting to itself. Will this cause the page to reload? and finally how can I cater the submit to do both things? Firstly validate through ajax and if everything is fine self submit and perform the php script even if javascript is disabled?</p>

I think i may have just forgotten the #. But why does getObjectById exist, if you can assign an element an ID?</p>

How do I get maximum offline storage from within a web site?
|
<p>I'm trying to develop a cross platform application, where the most obvious route would be a web site with JavaScript, but then I lose the cosy comforts I'm used to using in my C# desktop apps, like file system access etc. How do I go about accessing <em>similar</em> services from within the browser?</p>
<p>E.g. I don't need to access anything I don't create, so actual file system access is just a luxury. I can use whatever the browser offers for offline storage, but have no clue how to do this.</p>

Dismiss keyboard when user taps Mapview
|
<p>I have a UITextView in my Navbar that is acting as a search box. I would like to dismiss the associated keyboard when the user taps below the text box - namely on the MKMapView. However I can't figure out how to do this since it doesn't look like I can intercept touches from the mapview. </p>
<p>I have looked at a number of solutions, but none seem to work for my case as far as I can tell. Does anyone have a simple way to do this? I am a bit of a noob, so please let me know if I am not providing some relevant information, and please provide a few lines of example code in your answer if you can - I am still a bit shaky with terminology. Thanks!</p>

How to skip using __autoload?
|
<p>I have a php file which has multiple classes in it. I noticed that __autoload is being called when I instantiate any of the classes, even after the 'package' file has been autoloaded. This is worrying me, because surely if the initial 'package' .php file has been loaded, it is unnecessary overhead for __autoload when the classes have already been loaded. </p>
<p>I probably made a hash of explaining that, so here is an example:</p>
<pre><code><?php
class Class1{};
class Class2{};
?>
</code></pre>
<p>Then in another file:</p>
<pre><code><?php
new Class1;
new Class2;
?>
</code></pre>
<p>__autoload will be used for both Class1 AND Class2's instantiation... even though they are housed in the same file.</p>
<p>Is there a way to get around this?</p>
<p>Sorry if my explanation isn't very good, I'd really appreciate any help or tips.</p>

How do you create and use a Collection that has as one of its members a Collection
|
<p>I’m trying to create a Collection that will have a Collection as one of its members. The application is to track stock prices. </p>
<p>The primary collection should look like this: <strong>Symbol, Stock Name, (price collection’)</strong> </p>
<p>The ‘price collection’ should look like this: <strong>Date, Price</strong> </p>
<p>Some example data </p>
<p>APPL, Apple<br>
[1/1/2011,$245;1/2/2011,$247;1/3/2011,$242; .....]</p>
<p>MS, Microsoft
[1/1/2011,$35;1/2/2011,$32;1/3/2011,$42; .....]</p>
<p>So in c# how do I create a collection class that has a collection class as a member? Then how do I access the ‘price collection’ members of that collection? (I’ve managed to figure out the creation and able to add at both levels, but I can only access the top level to see contents. I can’t figure out how to access ‘prices’ that I’ve added nor can I see any of its methods </p>

PHP - Find longest date "streak" and "slump"
|
<p>I've currently got 2 dates in PHP - a 'start' date and an 'end' date. I have then created an array of dates, using a function I found called <a href="http://boonedocks.net/mike/archives/137-Creating-a-Date-Range-Array-with-PHP.html" rel="nofollow"><code>createDateRangeArray</code></a> (<code>$date_range</code>). For simplicity, the end date will always be <em>today's date</em>.</p>
<p>I've also got a separate array that contains a bunch of dates (<code>$valid_dates</code>) that will always fall between the start and end dates mentioned above. On those dates, 'something' happened - in this case, a training session.</p>
<p>I'm trying to get my head around getting the following:</p>
<ul>
<li>A range of dates similar to the <code>$date_range</code> array, populated with TRUE or FALSE based on whether or not a training session happened on that date. I'm happy for this to be an assoc array with keys named <code>date</code> and, say, <code>session_found</code> (bool).</li>
<li>The longest 'streak' i.e. the longest consecutive number of days that training sessions occurred.</li>
<li>The longest 'slump' i.e. the longest consecutive number of days that training sessions did NOT occur.</li>
</ul>
<p>Can someone point me in the right direction for getting the above info without using a <code>foreach</code> on the contents of the <code>$date_range</code> array and then having to use another <code>foreach</code> for the <code>$valid_dates</code> array on each item in the <code>$date_range</code> array? That is horribly inefficient ...</p>
<p>Sorry if I've over-complicated things with all that info but any help would be much appreciated.</p>
<p>I'm currently using PHP 5.4 on Debian Wheezy, if that helps (typical LAMP stack).</p>
<p>Thanks</p>
