• .NET Development DataGrid/DataGridView Bug with a Workaround

  You use the DataError event to validate formats in for a DataGridView.   OK, fair enough.   Works well enough . . . unless you have to validate a number.   If you enter text into a number field, a DataError event fired and you can show a MsgBox, as you’d expect.     Problem is, you no longer have a Null; you have a String of zero length, meaning you keep hitting the DataError event, event when there is nothing in the field because the Framework is trying to convert an empty String to a number.   You can’t leave the field.   Now, you could force the user to enter a zero (0) before leaving, ...Show All

• Software Development for Windows Vista Errors in winnt.h file using visual c++ 2005 express edition and mar. 15 sdk

  Hello. I get the following errors when I try to include winnt.h in my code. I tried using the newest sdk as well as the previous release, and both files seem to generate the same errors. This must be a common problem, but I haven't seen the answer. I'm including stdio.h, xlcall.h, windef.h and winnt.h in my code. Maybe I need to include another header. Any help would be greatly appreciated. Thanks.

• SQL Server HTTP access to Analysis Services 2005 ?

  Hi, Is there anything in store to allow Excel users not logged in a Windows domain to access 2005 cubes In SQL 2000 you can use an unsupported ASP script (provided by Microsoft) to allow these people to use cubes though HTTP transport. They do have a Windows account however they start their laptop in local mode, therefore normal access with a server name string is not an option for them. They have to use an http connection string.
