• SQL Server sqlcmd :r and spaces

  I've been pulling my hair out with this for a bit and thought I'd post a solution. The problem is that if the file name :r reads contains spaces, it almost always gives an error. The solution isn't great and if anyone has something better I'd love to see it: :setvar dir "C:\test dir\" :setvar file "my file.sql" PRINT '$(dir)$(file)' :r $(dir)$(file) GO :setvar file "my file 2.sql" PRINT '$(dir)$(file)' :r $(dir)$(file) GO :setvar file "my file 3.sql" PRINT '$(dir)$(file)' :r $(dir)$(file) GO Hope this helps someone. Thanks Robert, That only works if the filename is a constant. I suppose I could search and replace but then I'd have to hunt through the script to see if ...Show All

• .NET Development Problems with Synchronous Networkstream

  I'm trying to send a file using the Networkstream class, but some bytes were missing so I use the socket to send a message to the client after the bytes are received and the client waits for the message before it sends any more bytes. I'm using synchronous so instead of sending yet another messsage saying the bytes were sent, it will just wait untill there are bytes to be read and read them. The problem is that the client isn't sending anything to the server. I've looked at Networkstream.DataAvailable for the server's Networkstream and it's always 0... NS = networkstream You can pretty much ignore the other code, it's not important . . . Anyway, this is the code to the client: while ( BytesSentSoFar < Convert.ToInt32(FileSize)) ...Show All

• Visual Studio Team System TF26212 - work item type definition problem

  I've changed a work item type using witexport and importing it using: witimport /f <file name> /t <team foundation server> /p <project name> After importing, the work item type displays correctly, but when I try to save it, I get the following error: TF26212: Team Foundation Server could not save your changes. There may be problems with the work item type definition. Try again or contact your Team Foundation Server administrator. Unfortunately, the other items I found in the forums about this were unhelpful. My problem is slightly unique - Logging in as myself, I get the error above. However, a coworker logged in and did not get the error when saving. Any suggestions on how to correct this ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Pulling Data from ContentManager

  I've got a question on why to use the content manager. Say I have loaded a texture into the content manager - paddle = content.Load< Texture2D >( @"Graphics\paddle" ) as Texture2D ; If I want to access the data from the content manager, would I have to put something like this - sprites.Draw(content.Load< Texture2D >( "Graphics\\paddle" ), new Vector2 ( this .paddle1.Point.X, this .paddle1.Point.Y), Color .White); Or is there an easier way then that Cause if I have made a texture variable, then loaded it into the content manager, why couldnt I just call the variable directly like this - sprites.Draw( this .paddle, new Vector2 ( this .paddle1.Point.X, this .paddle1.Point. ...Show All

• Visual Studio Tools for Office RSS feed in Outlook

  How can I see if a MailItem is a RSS item using the object model // Johan As its name implies, I would expect the NewMailEx event to fire only for new mail. RSS feed items are not mail. You should be able to use the Folder.Items.ItemAdd method to monitor RSS feed folders for new items. What is it that you want to do with these items I don't write C# code, so I can't speak to the best way to check the type and cast. ...Show All

• .NET Development Reading SerialPort (with .Net 2.0)

  Hello, My robot sends me serial messages (packages) starting with a STX (0x02) character and ending with and EOT (0x04) character. Messages may have variable lenghts and within messages (except from first/last character) no other STX (0x02) or EOT (0x04) characters exists. My robot can send multiple messages at any time. How do I configure my SerialPort to extract individual messages from incoming data I was thinking of setting the 'SerialPort.NewLine' character to EOT (0x04) and use the 'SerialPort.ReadLine' for reading complete messages. But how can I make SerialPort execute an event if an EOT (0x04) character is received All tips are welcome. Henk Okay yes, I kn ...Show All

• Visual Basic Managed memory leak

  I am having a very strange memory leak that seems related to databinding. It is very hard to reproduce, so I won't post any code here to do so, but will just describe the problem. We have data entry forms which have controls which bind to custom business objects through a BindingSource object. On Dispose of the form, we call ClearBindings as described in: http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnwinforms/html/databinding_winforms10_11.asp#databinding_winforms10_11_topic11 However, our business object stay in memory after the form has been closed.

• SQL Server Can aggregate functions be used in a check-constraint or a computed-column?

  Hi, Can aggregate functions (e.g. Sum, Avg) be used in a check contraint or in a table's computed column Thanks! Green: I don't think you can use subqueries for either circumstance; therefore, I am not sure that you can apply either one to a table. I think that the best you can do for a function is a scalar function. Can somebody else verify this Dave ...Show All
