C# Signature:
[DllImport("user32.dll")]
static extern bool EnableWindow(IntPtr hWnd, bool bEnable);
VB.Net Signature:
Declare Function EnableWindow Lib "user32" (ByVal hwnd As Integer, ByVal fEnable As Integer) As Integer;
User-Defined Types:
None.
Notes:
The sample code below compiles and runs but seems to do nothing!
Tips & Tricks:
This function is useful if you want to mimic the functionality of a modal window without using form.ShowDialog() method. Disable the parent window by using this function.
Please add some!
Sample Code:
Class DK
Declare Function GetDesktopWindow Lib "user32" () As Long
Declare Function EnableWindow Lib "user32" (ByVal hwnd As Integer, ByVal fEnable As Integer) As Integer
Public Shared Sub DisableKeyMouseInput()
Dim lDesktop_hWnd As Integer
Dim lRet As Integer
lDesktop_hWnd = GetDesktopWindow()
lRet = EnableWindow(lDesktop_hWnd, False)
End Sub
Public Shared Sub EnableKeyMouseInput()
Dim lDesktop_hWnd As Integer
Dim lRet As Integer
lDesktop_hWnd = GetDesktopWindow()
lRet = EnableWindow(lDesktop_hWnd, True)
End Sub
End Class
Alternative Managed API:
The ManagedWindowsApi project (http://mwinapi.sourceforge.net) provides a
class ManagedWinapi.SystemWindow that has a settable Enabled property.
