I want to open a modal on that main page and load html content from a different page. I need to pass that variable to the modal that is opening and use it inside the loaded html content.
I have seen several questions similar to that in these forums but i don't see any that explain how I can tease that variable out of the loaded html content.
I know that i can make a GET request for that external html content, and I know that i can include the variable in the query string. But how do i get it out of the query string inside the modal?
All of the examples i see for getting things out of query string involve using window.location.href or something similar. Well that won't work for me because that returns the url of the main page I am on and not my modal popup.
Any suggestions?</p>

<p>Is it possible to retrieve the pervious upgradeCode that was used to install the same application?</p>
<p>I have given our application to many or our clients. </p>
<p>They install our application using the MSI.</p>
<p>Everytime I release a new version for bug fixes or minor upgrades. In the setup project properties I increment the version number and change the product code (I always leave the same upgrade code). And I set the 'RemovePreviousVersion' to true.</p>
<p>However, a few weeks ago, I accidently changed the upgradeCode and released a new version to our customers. It was only now that a customer wanted to know why they have other instances of the same application in their 'add remove programs'. It installs ok, but they have to uninstall the previous version. </p>
<p>I am wondering is it possible to get back the original upgrade that was used to install those versions. As I used the same setup project, I no longer have that upgrade code?</p>
<p>I still have all my original setups.exe that were built with the original upgradecode, but I am not sure if they can help me.</p>

2,095,343 | 2,095,344 | I can not connect to the phone for debugging any more | <p>After developing and testing for months my android application both on the emulator and on a phone, I suddenly can not connect any more to the phone in one of the two PCs I use for development.
One PCs runs Windows XP 32bits. Here everything is ok. But my main development machine is a Windows 7 32bits: Both of them run Eclipse Galileo. I can not get connected to the Samsung Galaxy S GT-I9000T phone from there. Two Sundays ago I updated my application last version to the phone. Went on vacations. After returning I upgraded the Samsung Kies suite to the new version 2. It is supposed it installs USB drivers for Windows. I also upgraded to Android SDK 9 and ADT 9 but I'm not sure it was after the problem appeared. Then I realized can not connect to the phone. My first suspect was Samsung Kies. But I made all these intallations on the xp PC and the connection works OK. Then I returned to the Windows 7. There is another driver called "USB Driver for Windows" which I have installed from Android's SDK "SDK and AVD Manager"/"Available Components"/"Android Repository" I tried to reinstall it. I deleted the package despite the warning it can not be undone. Then I tried to find it on the "Available Packages" but it was no more there.</p>
<p>I reinstaled Samsung Kies, Eclipse, Android SDK but the problem remains the same:
Another fact: with USB debugging active, Samsung Kies can not connect to the phone. It detects something is connected but it stays forever trying to connect.But it occurs also on the XP machine.
In summary:</p>
<ul>
<li>I can not get listed the "USB Driver for Windows" in the "SDK and AVD Manager"/"Available Components" for installation, even after reinstalling all the development environment</li>
<li>I can not get the development environment to connect to the phone for debugging.</li>
</ul>
<p>How to fix this?</p>
<p>Any hint is welcomed.
Thanks in advance.

<p>Is there any structured way to go from a managed thread ID to a process thread ID? Generally this is a bad idea because if your managed thread is recycled it could end up on a different process thread, but AFAIK, that can't happen with the UI thread.

5,357,403 | 5,357,404 | I'd like my private virtuals now, please | <p>What is the reasoning behind disallowing private virtual functions? </p>
<p>Empty private virtuals would have enabled low friction pure customization points.</p>
<p>Abstract functions have high friction and protected virtuals cause confusion and noise.</p>
<p><strong>Some further explanation:</strong></p>
<p>The Non Virtual Interface pattern separates the interface responsibility (public) from providing customisation points (virtual).</p>
<p>When using NVI in class design I have to make my virtuals protected.
Having the option to make them private makes the intent even stronger. It means that descendants can <em>only</em> provide customisation and there is no confusion over whether to call the base or not, in fact it is prohibited. There must have been a good reason to explicitly disallow it (Diagnostic: "Private method cannot be polymorphic"). </p>

<p>But typeof(null) is object, so null is just a value of type object.</p>

3,888,360 | 3,888,361 | User permissions binary/decimal confusion after unexpected behavior | <p>First of all I do not understand why some people are using binary number and powers of two for permissions. Is it because they stand for true/false with 1/0 from backwards relation?</p>
<p>Ex: <code>1010 means false, true, false, true</code> ?</p>
<p>My question is following. <code>15</code> in decimal is same as <code>1111</code> in binary, BUT:</p>
<pre><code>DEFINE ('READ',1);
DEFINE ('WRITE',2);
DEFINE ('EDIT',4);
DEFINE ('DELETE',8);
$current = 15;
if ($current & READ) print("can read <br />");
if ($current & WRITE) print("can write <br />");
if ($current & EDIT) print("can edit <br />");
if ($current & DELETE) print("can delete <br />");
</code></pre>
<p>This outputs that all permissions are allowed, as I expect. However, if I change 15 with <code>1111</code> then it shows only 3 of them that are allowed not all four (<code>delete</code> permission comes as invalid):</p>
<pre><code>DEFINE ('READ',1);
DEFINE ('WRITE',2);
DEFINE ('EDIT',4);
DEFINE ('DELETE',8);
$current = 1111;
if ($current & READ) print("can read <br />");
if ($current & WRITE) print("can write <br />");
if ($current & EDIT) print("can edit <br />");
if ($current & DELETE) print("can delete <br />");
</code></pre>
<p>Is not it strange? Do I understand it incorrectly? I need some help to understand this. Should I store permissions as decimals or binaries in db?</p>

4,394,164 | 4,394,165 | PHP Mailing Code sending mail to spam/quarantine | <p>The title explains itself. It is a website for in-house employees to buy and sell from each other. Its based solely around Microsoft Outlook emailing addresses. All the emails are supposed to be sent from the seller's email as they post items. Except when I enter <code><php phpinfo(); ?></code> on the action php page it tells me that the sendmail_from attribute thing is sending from a bogus email on the server. It seems to be the automatic email for the php script to send from. This may be why the emails are getting sent to spam, because the email is not valid. Also, I read online about having full and valid headers but most headers seem optional and i cant find anywhere that explains optimal headers. My mailing code: </p>
<pre><code>//send approval email to the approver
$from = isset($_POST['from'])? $_POST['from']:1;
$message = isset($_POST['message'])? $_POST['message']:1;
$message = $message . '<a href="http://dev-corkboard/newapproval.php?id='

// In case any of our lines are larger than 70 characters, we should use
// wordwrap()
$message = wordwrap($message, 70);
$to = '[email protected]';

$subject = isset($_POST['subject'])? $_POST['subject']:1;

<p>which I expect to remove the handler, so I can't click on it anymore. But I still want to be able on the other divs that has that class.
This is not working (I believe is because JQuery doesn't remove the handlers when a class is removed)
I've also tried with </p>

3,837,637 | 3,837,638 | Local variable in each class - python timed loop | <p>I have a python file in a continuous loop reading from an external file, I have a lot of different data points I'm reading and have a class (fb) that I'm calling to feed the locations of each point (m1.x, m2.x etc....) The file loops every 30 seconds. </p>
<p>I need a variable in the loop which is not reset for each instance I'm using. If I define it within the loop it's reset and if I use a global variable I can't use it for multiple variables. </p>
<p>So in the example below 'test' counts by one for all instance as its a global variable and self.X is reset after each loop. Neither of which do what I need. I was attempting to use threading but this causes even more problems with the modules I'm using. So if anyone has any ideas on how to create a local variable which is not reset within a class which is looping that would be great. Thanks. </p>
