• Visual Studio Express Editions How do I test for null date in SQL table?

• Visual C++ Halting Keypresses?

  Hi all,     I am writing a program that is supposed to lock a user from the common key presses, i.e. Alt + F4, Crtl+Alt+Del, etc.  I know I have to have case WM_KEYDOWN:     switch(wParam)     {     //The Keypresses     }     break; My problem is that I do not know how to halt the keys from doing anything.  I am certain that VK_F4 is for the F4 key, but how do I link alll of the keypresses of one command together, i.e. the keypresses for the Task Manager.  I also need to know how to make the window, that will disappear, to keep windows ...Show All

• Microsoft ISV Community Center Forums Control of graphs and organization charts

  Greetings to all! How can one control properties and methods of graphs and organizations charts For example, I am trying to change the background colour of  a graph in a Powerpoint slide through a Macro command, or modify any kind of object in an organization chart. I am guessing I need to create a reference to the graph object and then access its properties through it, but have been unable to do so. Thanks in advance for any help or suggestions!! Hopefully, you'll be able to get back to us with more details, but the engineer did have some general suggestions: I have reviewed the link. However, I ...Show All

• Windows Forms DataGridViewComboBoxColumn not displaying stored value

  Hello, I am having a lot of trouble with the datagridview. My datagridview holds data of the child table. It does populate fine. However the problem comes when I want to add a combobox to the datagrid. Toward the end of the code below I add a combobox and bind it's source to the appropriate look up table. When I run the application, the column is added and it does have the values of the look up table, however it does not show the currently selected value in the database. It comes up blank. Also, I use the following statement: DgvCalls.AutoGenerateColumns = false ; My understanding is that this should not display any columns unl ...Show All

• Visual Studio 2008 (Pre-release) Pixel width "Thickness" for shapes

  Is it possible to draw shapes with a single pixel width I am working on an engineering program in WPF and need to scale drawings. The current thickness of 1 is more than one pixel (presumably anti-aliased) and is very "fuzzy" - that's an engineering term! The same drawing drawn with GDI looks much crisper - another engineering term. Ideally there would be a special thickness, say 0, which would always draw at one pixel width no matter what scale transform was applied. excerpt: As I was saying earlier, to accommodate the high-resolution displays, we need to get developers to stop specifyin ...Show All

• .NET Development Taskbar resize notification

  Hi All I have a windows Form based application which is developed using C#.
