• Windows Forms how to change the state of checkbox without showing the error messagebox again?

  hi, following is the simple code private void cb8_CheckedChanged(object sender, EventArgs e) { if (cb12.Checked) { MessageBox.Show("You can not choose this channel. \n Please uncheck Channle D first", "Channel Tangly", MessageBoxButtons.OK, MessageBoxIcon.Error); cb8.CheckState = CheckState.Unchecked; } else ... If cb12 is checked, an error message box will be shown when user check cb8... So the checkstate of cb8 should be unchecked... However, with the above code, since the state of cb8 changed again, the error message will be shown again... So user had to close the error message box twice... Is there any way to solve this Thanks a lot! ...Show All

• SQL Server Stored credentials on Shared Data Source

  I'm trying to use stored credentials to enable caching. I've created a special windows user account with minimum permissions for just this task, and once set up, it works great (almost). I can update the shared data source using SQL Mgt Studio or directly via the Report Manager to use a set of - windows - stored credentials. But I don't seem to be able to do the same via VS.NET 2005. I can only store - SQL - credentials, which I have no need to enable and no desire to add to my surface area. The problem lies that every time I deploy any report that using that data source (which is nearly all of them), the data source is re-published, which wipes out the stored credentials and caching immediately stops. I've tried messing with the ...Show All

• Visual Studio Express Editions template link errors

  I've been looking for a solution for this all day now, and it's driving me crazy. I have a C++ couple of C++ template classes that I'm using in a test executable for a DLL I built. The templates are used in the DLL as well, but in all cases that I use it, to avoid errors, I have all the template code in the header, so when it's included all the code is available for the compiler to do the type resolutions. When I build the DLL, it compiles and links just fine. However, when I build the executable, I get unresolved token and unresolved external symbol errors for the template, but only for the one that I use in the executable, not for the ones used in the DLL. I have tried to change the type temporarily to int and have copied and p ...Show All
