• Visual Studio Team System IDE Attempted to read or write protected memory

  I am seeing these errors frequently with VS 2005 RC1. I do not recognize any pattern that causes the errors, but I am going to guess that it is somehow related to aborted a debugging session on a webtest because that is what I was just now doing when I got the errors. --------------------------- Microsoft Visual Studio --------------------------- Attempted to read or write protected memory. This is often an indication that other memory is corrupt. --------------------------- OK   --------------------------- followed by: --------------------------- Microsoft Visual Studio --------------------------- Unspecified error -------------- ...Show All

• SQL Server How to upgrade from SQLXML3

  I have written a whole bunch of XML and XSD files for SQLXML3 but now with Yukon-Beta2 I find no way (and the docs pretend it has never been there) to actually use these files with SQLXML4! ! It can't be that I really need to re-design all these schemas and convert them to SP's and then REWRITE my apps which used XPATH over HTTP queries to utilize the new SOAP functionality. Any help would be apprechiated! Hi Todd, thanks for the answer - I was guessing such. I just find it amusing that noone bothers to mention it - officially!! Even NO WORD on www.sqlxml.org or any other blogs or sites. ...Show All

• Software Development for Windows Vista Notification on Windows Text change

  Hello, I have a question in SDK windows programming. I have a window control, implemented as an editable control for user to enter text. User can add text in the window control either by typing through keypad or copy/paste using mouse. I call GetWindowText() to read text from the control.

But I would like to know if there is any way to get notified, when there is a change in text on a window control Your response is appreciated. Thanks. Correct ...Show All

• Visual Basic Return the line number where an exception has occurred.

  I am looking for a method to return the line number of the code where an exception has occurred so I can include it in my alert message. Does anyone have an example that would help identify the location of the exception. Any help would be greatly appreciated. In a debug build where you have debug symbols the exception's stack trace should automatically include that information. I wouldn't recommend displaying exception messages to an end user. ...Show All

• Visual C# Nice Threads!

  I could really use some help here... I am using C# 2005 and have created a splash screen that runs on a seperate thread. I can invoke the splash screen in the Main() method, but then I can't get rid of it! I am attempting to put a line in the Form1_Load (or maybe Form1_Shown) that calls a static method in the splash screen to close that form. But, when I do so, it complains about an invalid cross-thread operation. How can I get this screen to close Here are the relevant parts to my splash screen: // Static Public Method to launch Splash Screen static public void ShowSplash() { if (ms_frmSplash != null) return; ms_Thread = new Thread ...Show All

• Visual C# Threading - ActiveX Events/Objects

  Hi, I have a threading problem that drives me absolutely nuts and I don't know what to do: I'm using an ActiveX object and subscribe to one of its events. Whenever I execute the method that drives the event, a couple events are triggered. The event response holds an ActiveX object which I need to work with. What happens now is that whenever the event response returns it runs on a different thread. I want to store the event response activex object in a Hashtable which was created on the main thread. Now, when all the events are done, I continue processing on the main thread. But here's the odd thing: All the actvivex objects in the hashtab ...Show All
