When I am using Visual Studio.net in the debug mode, I want to be able to increase the size of values that can be displayed. For example when using the "watch" or other debug windows, I know I want to see a field that is 8k. However, the size of the display is truncated somehow. I want to be able to see the entire field so that I can copy and paste the results to notepad. What would I need to do increase the size of the debug windows?

I've been trying to use a browser other than IE in VS.NET with no success. The default browser on my PC is Firefox, and it is also the default browser for opening web documents from the Solution Explorer in VS.NET. But when I click the Play button or hit F5, it is still IE that is being launched. Is there a way ? A registry key somewhere ??...or something obvious that I didn't see...or maybe it's illegal to do it ? ;-)

I am runnning some very simple performance tests using a vb.net winform to invoke a vb.net webservice. The webservice simply returns a string literal. I invoke the service 1000 times in a row and note some timestamps for reporting at the end of the test. When I run this using play in VS, the test takes ~16 seconds. When I build the exe and run it, it takes ~4 minutes.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
