• .NET Development .NET version 1.1 and 2.0 co-exist?

  I recently installed .NET Framework 2.0 without removing version 1.1. I initially thought that like Service Packs, the newer version will overide the older version. Now in the Add and Remove applet, both version 1,1 and 2.0 are there. What is going on Should I remove 1.1 now that 2.0 is there You don't need to have 2002 and 2003 installed. .NET 1.1 applications will automatically run on .NET 1.0 Framework without any troubles (as long as you don't use .NET 1.1 only features). There is currently a project under development at Microsoft codenamed MSBee. This project will enable Visual Studio 2005 to build .N ...Show All

• Smart Device Development WaitCursor not being displayed

  We recently ported a mobile application to .NET Compact Framework 2.0, and we're seeing a case where we set a WaitCursor, but it is not getting displayed. It was being displayed with .NET CF 1.0. The WaitCursor is set from the event handler for a button click, which starts a relatively long "Save" operation. The call stack at the point where we set the WaitCursor is shown below. Notable is the fact that once condensed, the call stack looks like: > Event handler for Dialog2 <-- WaitCursor set here, but not shown > ShowDialog for Dialog2 > Event handler for Dialog1 > ShowDialog for Dialog1 Does anyone kno ...Show All

• Visual C# Why is Generic.List<T> not ICloneable?

  I'm definitely missing here something. What was the reason not to implement ICloneable on the generic list Is it supposed to use ToArray() if I need a List with the same elements (value or reference types) Ok. It was stated that I should use copy constructors (as far as I understand - constructor with ICollection in my case). http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=5836&SiteID=1 Are there any other "bad" features of ICloneable except type unsafety (returns an object that must be downcasted). Can anybody, please, provide some material concerning this ...Show All

• Visual Studio Team System Lock level of file superceded by check out

  When check out operation is performed on file, the lock set will be that of the check out option specified. It may lead to some not entirely obvious consequences. Obvious example 1) No lock on file prior to check out 2) After check out is performed with lock option other than "None"("Check-out" or "Check-in" lock), the file is editable and has changes "Lock,Edit" associated with it (in "View Pending Changes" window) Not so obvious example 1) Lock the file prior to check out ("Check-out" or "Check-in" lock) 2) After check out is performed with "None" lock op ...Show All

• Visual Studio 2008 (Pre-release) milcore.dll missing from my system?

  Hi guys, I'm finally getting around to playing with WPF. I created the simplest possible app that is just supposed to show a window and uses the simplest possible msbuild file. It compiles and builds 100% fine. But when I run it, I end up with a DLLNotFoundException triggered by a missing milcore.dll file. My dev box has the following software on it, WinFX Runtime Componenets (Sept CTP) WinFX SDK (Sept CTP) C# Express Beta 2 (Although I'm currently just building everything from the cmd line) I've searched my machine for milcore.dll and I can't find it. Searching the web for a solution has also turned up a blank. Any ideas Thanks. ...Show All

• Windows Forms How do you get the row number from datagridview

  I added a datagridview to a form programmatically. One of the columns is a combobox and one of the columns (caseID) is not visible. All columns execpt for the combo box are text boxes.

• Game Technologies: DirectX, XNA, XACT, etc. Overlay Graphics on Direct3D

  I have a Direct3D-based game and I would like to overlay an information box ontop of the game. The only sample code I found was using the depreciated DirectDraw and I was wondering if there was another way to do it. An application that has accomplished what I am trying to do is a program called Xfire and a screenshot of the program is here: http://media.xfire.com/xfire/xf/themes/XFire3/images/tour/tour_image_4.jpg As you can see they have overlayed a box ontop of the game, which is exactly what I want to do, just not using DirectDraw since it is depreciated. ...Show All
