• Windows Forms LockScreen, get and change Keys.

  I have a Windows Form that I have set to go into Full Screen by setting the border to "none" and the WindowState to "maximized". On the forms "OnKeyPressed" Event Handler I have a switch that is supposed to check if the keys: Control, Alt, Delete, and Tab were pressed. If the user presses the key, it changes its value to the 'A' Key. (Meaning if they press Ctrl, Alt, or Del, or Tab it is like they press A instead. But the problem is that the keys are not being changed. It registers that they have been pressed though. Here is my code: private : System::Void OnKeyPressCancel(System::Object^ sender, System::Windo ...Show All

• .NET Development Dates and the database

  I'm really having trouble figuring out how to handle dates within my database. SQL is really picky about date fields, and so I'm having trouble. 1. If I want to leave a date field null - I can simply omit it from the insert statement, but then once it is entered and I try to "null" it out then the database gets mad at me. 2. If using .NET I try to check for validity on a null date - it returns as valid because the time element of the date sets itself to 12:00 - Which is unacceptable to SQL. 3. If I have a text box to receive a date as input - and I assume an "invalid" date means no date at all - so I omit it from ...Show All

• .NET Development Developing Plugin Architecture for 2.0 and 1.1

  I'm interested in building a plugin architecture for a .NET 2.0 app (C# for those who care).  I'd like people to be able to create plugins using .NET 2.0 or 1.1. Is there any good method to define a single library that has the interfaces for both 1.1 and 2.0   Do I just have to implement the library in 1.1 if I want support for both   I tried implementing "identical" libraries (one for 1.1 and one for 2.0) where both had the same GUIDs set for the interfaces and the plugin host application views the intefaces as different. the key is interface. read more about this approach in this ar ...Show All

• Visual C# Interaction between main program and dll

  Hi all! Could anybody give me an example of following: 1) Main program in C# that calls function Foo(Handle_of_My_Form) declared in my dll. 2) Dll in C++ with implementation of Foo that just calls PostMessage(Handle_of_My_Form, WM_USER, 0, 0). 3) Finally, main program catches this messages and show MessageBox "All right! I've caught it!". Please, help - I need to do this task as soon as possible. -- Sincerely, Dmitri The function is probably getting exported with a mangled name. You can check that with Depends.exe or Dumpbin.exe. The reason is that the "C" fell off in your code. extern __declspec(dlle ...Show All

• Windows Search Technologies Address bar lost!

  Hi, My address bar remains invisible even i choose view->toolbar->address bar. I used oleview.exe to have a look at one copy of explore.exe but I don't think I have changed anything.

• Windows Forms Z order with MDI

  Ive got a MDI parent with numerous MDI children, wondering if I can modify the Z order programmatically of the MDI children. I have 2 or 3 different MDI child windows. The user can Tile/Cascade/Maximize these but whenever I open or close a window, or return to Tiled mode from another state, I automatically re-order the windows to ensure that a specific one is at the top, and (if it exists) a specific one at the bottom. In VB6 I simply set the Z-Order of the ones I wanted to be at the top/bottom and this worked 100% of the time. When I converted to .Net I used SendToBack and BringToFront .. ...Show All
