• .NET Development Unable to load Cursor object in VS2005/Vista

  Hello! I'm developing a C# user control application in Visual Studio 2005 on Windows Vista.  I recently added the following lines of code to my project, and now it blows up.   // In the class definition... private Cursor _cursorBox;   // In the class constructor... _cursorBox = new Cursor("box.cur");   When I run the control, I get an error dialog that says the following:   Failed to create UserControl 'ActiveLayoutWorks.LayoutWorksControl' The error message was 'Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.'   I can only assume this has something t ...Show All

• Visual Studio Package 'Visual Web Developer Trident Designer Package' has failed to load properly.

  I've been using VS 2005 Beta 2  for a few weeks now on a win2K machine, with nothing else installed at all. It's been working fine every day for three weeks, but today I get the following error message whenever I try to open an .aspx file.

• SQL Server Setup failed - no package <sqlncli.msi>

  I tried to install a sql 2005 desktop engine. This fails with the error: An installaton package for the product Microsoft SQL Server Native Client cannot be found. Try the installation again using a valid copy of the installation package ‘sqlncli.msi’   I used a fresh, new download SQLEXPR.EXE. What shall I do   I had a similar problem installing SQL Server 2005 Standard Edition (not the beta) on Win 2000 SP4.

• Game Technologies: DirectX, XNA, XACT, etc. The values used in the attempt to create the GraphicsDevice were invalid.

  Is this because my graphic card does not support shader model 2 I didn't even know of this requirement till I saw it on the readme file. Time to change my geforce4 I got it to work. Add this line after the Graphics component is created: graphics.AllowMultiSampling = false ; Then in the WindowsGame_Starting function set graphics.AllowMultiSampling equal to false again. ...Show All

• SQL Server Filtering on a date comparison in a dimension table

  I'm trying to create a Customer Count measure. Each customer has a open date and a close date in the Customer dimension, so I need to filter the count based on this date range. For each time period the count should include customers where Open Date is <= the current time period and CloseDate >= the current time period. The measure needs to work for any time granularity (years, months, etc.). I think this query is close but it is returning a 0 count for each month: With Member [Measures].[Customer Count] As Count ( Exists ( [Customers].[Customer ID].Members, Filter ( [Customers].[Customer ID].[Customer ID].Members, [Customers].[Customer Open Date].CurrentMember.MemberValue <= ...Show All

• Smart Device Development Is there a reolution limit on creating a bitmap in CF1.0

  Is there a resolution limit for created Bitmap images in CF1.0. When I import a small (320x240) type image, it works fine. But when I try to bring in a higher resolution photo, the Bitmap creation fails. I can take the same code, resize the embedded image to something smaller, and it works fine. I can also take the same code with the big images, run it on the desktop, and it too works fine. I check the memory on the device and there's plenty. It almost looks like the CF has some limit to the size of how big an image you can bring in. Thanks Thanks Ilya, That was the answer. I forgot about when you expand the jpeg into the image, it takes up ALOT more space. (100k => 900k for one jpg, 990k => 11.9 MB ...Show All

• Windows Forms StartupNextInstance and ClickOnce

  I'm trying to use the StartupNextInstance event to get the values passed to the My.Application.Deployment.ActivationUri.AbsoluteUri of a clickonce application when it is started again. If this were a standard application I could obtain the startup parameters from e.Commandline , but this is empty when the application is launched via clickonce . Is it possible to get the startup URI of the second instance from the StartupNextInstance event If you haven't had a chance yet, take a look at the "hack" in the last post on this site: http://dotnetslackers.com/newsgroups/microsoft_public_dotnet_framework_windowsforms/ng-156718_VB_NET_StartupNextInstance_and_ClickOnce_NET_2_0_.aspx This should be able to get you past this bug ...Show All
