• Visual C# C# analog clock runs slow on some computers

  Hi all, I have a problem with the System.Threading.Timer class that I am using for my clock. The clock runs faster on an Intel box than it does on an AMD box and it has nothing to do with the CPU speed. Has anyone come across this before Any suggestions would be much appreciated. Ok, I have found that it is not a cpu problem as I have another box with an AMD Duron XP 1000MHz(5x200) which runs at the correct speed. I have tried it on another computer (an intel celeron 4A, 2400MHz(6x400) and it runs slow. ) There doesn't seem to be any link between the CPU and the slow clock problem. I thought now maybe it could be a video card problem, but ...Show All

• Visual Basic Running an external application

  Hi All: I want to program a button's click event to run a Windows batch program.  Is this "legal"    If so, could you either provide me with an example or point me to where I can find some documentation on this.  If not, please tell me how this little feat can be accomplished elegantly.

• .NET Development Question on Threading...

  (VB.NET) So I finally understand how it works, incorporated on one of my long processes and it works.  Great.  But now when I run the process (showing a progress bar) I can only do other tasks after the progressbar finishes.  The Setup: I have a subroutine that creates about 5 excel spreadsheet from records in a database.  The progressbar shows for each file creation.  As it's creating a file I can't access my Menu (File, View,etc..) until a file is done.  The menu item opens but the process stops.  After I release the menu item, the process continues. The threading code is as follows: Private Sub Excel ...Show All

• Visual Studio 2008 (Pre-release) WCF Team question

  Hi Team, The current 'WCF documents' isn't good to create real application, so I don't know if it is possible, but .... I think that WCF Team create 'unit test' for code validation. Does WCF Team can 'share' your unit test Isn't necessary a 'compiled' version. With 'unit test' we don't need many documents to understand how to use WCF. It's better than 'examples'. Without it, we have two options : 1) Wait the final release of documents; 2) Write many questions in this great forum. Thanks, Alexnaldo Santos Yes, we do have unit tests. Quite a lot of them. The problem is that ...Show All

• .NET Development How to change the permissions on a LMShare

  Hello everybody, I search for a class in the .Net Framework 2.0 to change the permissions on a LMShare but I can't find one. Has anybody a code sample for this. Thanks Peter Peter, there was no support for this in the managed APIs in V1.0 or V1.1. But there's new APIs for manipulating ACLs in V2.0 that are integrated with the existing IO package. Use the new Get and Set access control APIs on the Directory class (which of course, can be used to access a share) to set and view permissions. The documentation has examples of how to use the new APIs, which include FileSecurity, and DirectorySecurity (many o ...Show All

• .NET Development Launching a COM server from a service on WinXP 64-bit

  I have a 32-bit application that gets launched by a service. It is basically an MFC out-proc server. On a 64-bit machine, I am seeing an issue where a client is unable to communicate with this COM server. My assumption is since the application which is 32-bit is getting launched from within a service, there is some kind of a security issue. The COM error I get is 80080005. Is it possible at all to have a service launch a 32-bit out-proc COM server on a 64-bit platform and have an client communicate using COM Note that all of this works on a plain 32-bit OS i.e. I am able to launch the COM server from within a servic ...Show All

• Visual C++ visual c++ 6.0 vs visual c++ 2005

  I am looking forward to upgrade VC++ 6.0 to Visual C++ .NET 2005. But there are things I need to know before I do... 1. What are major changes in the "object class" structure ( if there are changes). 2. Do I need to make changes for the MFC libraries that I used while coding with VC++ 6.0 when I upgrade to VC++ .NET 2005. 3. In VC++ 6.0 I can use openGL and MFC together, and I can run OpenGL in a window with the  integration of OpenGL and CDC ( class of device-context objects). Can I do the same in VC++ .NET 2005 4.
