Visual Studio Express Editions Null Reference Exception
For some reason i keep getting this "Null reference exception was unhandled - object reference not set to an instance of an object" Does anyone what this or what is could be causing it. I'm using arrays to store stuff which then makes an instance of a panel. I have 4 of these, they are all identical and use the same panel, but one of them refuses to work and I get this message, I've checked it over and can't seem to see anything different between that 1 and the other 3. ReneeC, everyone is both political and social, however that is not why we are here. There are many forums for discussing those subjects. This is a programming forum and I respect it as such and will not be baited into other discus ...Show All
Visual Studio Invalid argument for database
Hi, I have a report that is connecting to two different databases and retrieving data from a stored procedure in each. My problem is that when I try and set the destination of the database at runtime, I get the following error: Invalid Argument provided. Failed to open a rowset. Error in File C:\DOCUME~1\JAMES\LOCALS~1\Temp\temp_{5E8F9D66-6EFF-47E9-96F7-65D32A761DCC}.rpt: Invalid argument for database I have other reports connecting to the two databases and I am setting their destination at runtime with no problems.

Strangely enough, when I set the designtime location of the database to be the location that i am sett ...Show All

Hi All, I inherit an existing project that contains old MFC/ATL C++ code. when I compile the code with VS2003, it compile fine. With VS2005, I got 409 errors.

After converting to VS2005, it has 409 compiled errors. It ...Show All
.NET Development guid type conversion for sql key compare
I have a commerce system that uses guid type keys extensively. I cannot seem to get the right format so compare an guid with another for a select statement. For example: sqlreader record that includes a data field of type guid - Dim strGuid As String Dim guiGuid As New Guid guiGuid = myOrderReader.Item(7) - from table read item(7) is a type guid value strGuid = guiGuid.ToString Dim strOrd As String = "SELECT purchase_order_closed FROM dbo.mf_purchase_orders WHERE purchase_order_guid=" & strGuid This gives syntax error but the conversion to a string value works. How do you format the value in read field myOrderReader.Item(7) so that you can compare it in a select type statement as ab ...Show All

May i know how to check the barcode reader has read a barcode and display the numerical value of the barcode and retrieve information accordingly from time to time.

.NET Development Requested Service not found.
I'm moving a Remoting client and server from .Net 1.1 to .Net 2.0. The code worked fine in .Net 1.1. Now, if I connect to the server using a configuration file, everything works ok. But if I connect using RemotingServices.Connect(), I get a remoting exception "Requested Service not found." I've checked and double-checked to make sure the URL is correct. Since the exception originates in the server, I believe the URL is ok. Any ideas ...Show All

Game Technologies: DirectX, XNA, XACT, etc. Displaying textured 3D objects
Hi there, I've been working my way through the tutorials at http://xna101.spaces.live.com/ , and I am stuck on lesson 16, the first 3D tutorial. The download of die.x didn't work, so I whipped up my own little 3D cube in Blender and applied a simple 64x64 pixel texture to it and saved it in DirectX format as cube.x. I was able to add it to my Project fine, but when I try to compile the program, it has all sorts of trouble understanding any texture I put on the thing. It will say the texture file is not found in the debug/bin directory; or it will give me other error messages about the structure of the texture file. I tried saving the cube as cube.3ds and cube.x3d and whatnot, and none of that worked. (Indeed, the Project didn't even rec ...Show All
