• Visual Studio 2008 (Pre-release) Binding To a User Defined Dependancy Property

  I'm still new to WPF so I'm sorry if this doesn't make sense. I have created a control that inherits from UserControl called MyUserControl. I want to use this in another project and have that working. I then created a dependency property called TestText that is a string. This will get displayed in the text box via data binding in MyUserControl. If I explicitly set this it works just fine. I want to be able to bind to that property from the window that is hosting the control. However when I try to bind in XAML it doesn't seem to update the field. When I bind using code it works. I'm fairly sure my XAML is okay because I can bind the to a label's content alright. Here is the code I am using: MyUserControl.xaml.cs: namespace CustomControlLi ...Show All

• Visual Basic shell.run only once in a set timescale.

  Sorry for the vague header. I have the following code: Sub OnCall (State, Name, Number) Shell.Run "C:\YACTextSend @CALL" & Name & "~" & Number End Sub Which enables a prog called Float's Mobile Agent to send incoming mobile phone caller id info to a prog called YAC eventually to be displayed as a caller ID pop-up in Media Center by MCE-YAC. It works but for one problem. OnCall is invoked at each ring so my added snippet above launches YACTextSend and pops up a caller ID window at each ring of an incoming call. I am not skilled enough to rewrite Float's prog (written in Delphi) so I have to work with the above code. Is it possible to modify my code to run YACTextSend only once in say a 20 seco ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How does Vector3.Transform work?

  I have the following matrix 1 0 0 0 0 -1 0 0 0 0 -1 0 0 1 0 1 and transform a zero vector by that. There is a transformation in the matrix, but I can't figure out how the math is done. Shouldn't this just be a 4x4 matrix multiplied by a 4x1 matrix For the fourth component of the vector, I tried just using 1. But when I multiplied them together by hand, I get a 0 vector. What am I missing Thanks. -Nick Note: - XNA and DirectX use ROW VECTORS ON THE LEFT. - This means that translation lives on the bottom. - Point transformations assume a "1" as the fourth vector element. - Normal transformations assume a "0" as the fourth vector element. In your example, a vector V (0, 0, 0, 1) times your matrix M will mul ...Show All

• Software Development for Windows Vista Force workflow to complete

  I've 3 activities in a sequential workflow, and I've added some coding in completed event. In the 2nd acticity, I want to force the workflow to complete based on some conditions, so it can skip 3rd activity and jump to the end of the workflow, and run the coding in completed event. Is it possible to do this ! Your original post sounded like you want the workflow to complete, not terminate. If you use a TerminateActivity or throw an exception, your workflow will terminate. You'll get the WorkflowTerminated event instead of WorkflowCompleted. Using dynamic updates (WorkflowChanges) is extremely inefficient. Dynamic updates are not recommended for implementing normal business logic. It's only meant for ha ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA Academic Edition?

  Hi all, I was just wondering about a rumor mentioned in a couple of game news websites, where they hinted at the fact that any Uni partnering with MS would get an elusive "Academic Edition" What would that mean exactly Would the Academic Edition be like XNA GSE, but with some features of XNA Pro Does such an edition exist anyway in the first place I'm quite interested in this as I'm a lecturer in Game Dev, in one of the most active Unis in Australia (RMIT, in Melbourne), and I've been recently quite pleased with my XNA experimentation Cheers Thanks a lot, Dave! Either way it's fine with me...I just wanted to be sure there was no extra "feature" we were missing Th ...Show All

• Visual Studio Tools for Office Deploying VSTO Word Project: could not find or load customization assembly

  Hello! I developed a custom task pane with VSTO for a Word2003 report and now I would like to enable access for my clients to this document. I copied the document to a server folder in my intranet and tried opening it, but I got the following error:: "The customization assembly could not be found or could not be loaded" "The customization does not have the required permissions to execute."

• Visual Basic TextBox Input Validation

  Greetings: I'm trying to get a textbox to only accept the input of numbers, ".", and the back key. I modeled this on the example in the MSDN help files, which is close to what I want and works just fine, but this tweak doesn't work. No input is accepted. The debugger will display that e.KeyCode is "NumPad5{101}", for example, but the debugger slides right over the first Case where I'd expect it to be accepted. Any other key gets the same result.
