• Visual Studio Team System Microsoft Project Plan (.mpp file) in Project Portal always locked

  Hi, Was wondering if anyone has seen this problem and possibly have a workaround for it. If we create a project plan using Microsoft Project 2003 (or 2007), publish the plan to the team server and then save the .mpp into a document list in the Project Portal. When attempting to edit the file project always displays the error "The file is locked by another user", read-only, notify, etc.. However the other user is me! Sometimes the error can be avoided by deleting Temporary Internet Files but not always. Curiously this only affects .mpp files that have been associated with a team project and are stored in the project portal. Storing them on the file system, or storing unbound plans in the portal works just fine. ...Show All

• Smart Device Development Serial Port Communication

  Hallo, I wrote a little prog, which sends a message and the messages md5 over the serial port: I'm using Visual Studio 2005.NET, PocketPc-Emulator and a virtual serialport-driver. This way I connected the emulator to COM2 and COM2 to COM15. So I can send and receive Data via the emulator on COM2 and via Win32-Application on COM15. For testing I write all incoming Data on the emulator to the serial output. Private Function com_sendString(ByVal toSend As String) As Boolean Dim hash As String hash = "##HASH:" & md5(toSend) & "##" Try If (serialPort.IsOpen = True) Then serialPort.WriteLine(toSend & hash) Else MsgBox("Port is closed!!")

• Windows Forms Wizard wierdness.....

  Can anyone point me to a good tutorial on how to use the SqlDataAdapter configuration wizard I used the wizard to create a dataadapter for a table I had just created. I checked in the advanced options and saw that I should be creating Update, Insert and Delete commands. The SQL I specified in the query builder is "Select * From <TableName>", with the approriate table name in place of the place holder. I tell the wizard to finish and it tells me that it created Insert and Delete commands but it did NOT create an update command. I can go an create my own updatecommand in code but thats a pain compared with the ease of using the wizard. Is there somthing that I am doing wrong to not get the update command to generate proper ...Show All

• Silverlight (formerly WPF/E) New XAML elements do not display immediatelly

  I created a test HTML page containing a WPF/E control - Canvas, clickable Rectangle that covers the entire canvas, TextBlock at the bottom of the control that displays a message about the coordinates of every click. On every click after displaying the message, I create a small ellipse(circle) and add it to the Canvas at the point of the click. It all works fine when the entire page is visible in the browser, BUT in a shorter browser window, where the TextBlock is not visible, the clicks do not render circles, UNTIL I scrolled the browser down and the TextBlock became visible. At this point all circles that should have been rendered moments earlier, appeared. When clicking while the TextBlock is visible it all works fine. Scroll it ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Sampler state broken?

But now it has no effect whatsoever. Anyone have a clue why this is the case and/or how to solve it please Thanks. This is because the default ...Show All
