• Windows Forms Flicker and Crash problem in VS.NET 2005 Pro

  I'm not sure if this is just me, but... Has anybody noticed an annoying problem in VS .NET 2K5 where you switch from code view to the Form Designer, and your mouse pointer starts flickering and changing among a few mouse pointers (ex. cross, hourglass, pointer, etc.)   This has happened to me a few times already and I havent' found any other common denominator other than the switch from Code View to Form Designer.  Thanks.

• Windows Forms TabPages and UserControls growing to over 30,000 pixels in Width and Height in Designer (2005 beta 2)

  I’m having some major sizing issues with controls in designer view. To be specific, it   seems that controls within container controls such as TabPages will randomly outgrow their parent controls to a very large size (~30,000px! ).   Even when trying to manually edit the designer code, as soon as switching back to design view, the weird numbers are back. Here's a link to a screenshot: http://www.bugben.com/showcase/30000.jpg Has anyone else seen this Or have any suggestions Yes. Several times. Still no luck :(. I seem to still be running into this problem even with new forms I create. O ...Show All

I can read them just fine, but i cannot write to them. it gives me an unable to write to registry error, make sure it is not readonly. Well its not read only becuase i can write to it in regedit.

• Visual Studio Team System Could just be a bug! - loading webtest to loadtest

  Hi guys, I'm using a trial version of Visual Studio 2005 Team Suite Edition. I was trying to create a new load test using the wizard.

I realise that I couldnt find the webtest from the list (Test Mix - Add - /All Loaded Tests - Available tests) I then restarted Visual Studio 2005 Open up the load test and edit the test mix - now I can see all the Webtests, including the recently added one. Does anyone have the same problem Can you still reproduce this   Are you certain the web test build had completed ...Show All

• Smart Device Development is there IJW support for smart devices?

  I am attempting to mix unmanaged (C++) and managed (C#) code. Normally I would enabled CLR support for the C++ file that calls the C# code and rely on the IJW support in the linker to handle this. However, in the smart device application I am attempting to build, I don't see the option anywhere in the properties (for the project or the file). When I attempt to build, the compiler complains that managed code requires a /clr option. If I add it manually to the compiler flags (via the Command Line property) the compiler reports /clr as an unknown option. This makes me wonder if /clr is supported in the compiler for smart devices. Anyone know ...Show All

• Windows Forms Deriving from abstract UserControls

  Can you use abstract UserControls I created a UserControl called Dad. Marked it as abstract. I created a class Son and changed it to: public class Son : Dad { public Son() : base() } If I 'View Designer' on Son it fails with a message saying ... The Designer must create an instance of type 'Windows.Application1.Dad' but it cannot as the type is declared as abstract.

• .NET Development Trace Listener

  Hi All, I've created a Trace Listener application that streams to a text file. The app is working but now I am at the point where I need to attach it to a certain application running on the target machine. Do I 'HAVE' to attach my Trace Listener to the process in order for it to capture the target app's trace messages Or should the Trace Listeners collection just pick up any trace messages from all applications on the machine... I found this article which is quite interesting, but wondered if I can get away with not going down the Kernel32 route.. http://www.codeproject.com/vb/net/VisualTraceListener.asp Any help would ...Show All
