Sorry... Try this code:

\\\
Private Declare Auto Function FlashWindow Lib "user32.dll" ( _
ByVal Handle As IntPtr, _
ByVal bInvert As Boolean _
) As Int32
..
..
..
Public Sub Flash()
FlashWindow(Me.Handle, True)
End Sub
///
 
Can you translate that code in C++?

Gif,

There are three steps to getting this to work:

1. Make sure that the following Imports statement is at the top of the
class file where you want to use an API:
Imports System.Runtime.InteropServices

2. Declare the DLL import:
<DllImport("user32.dll")> _
Private Shared Function FlashWindow(ByVal hwnd as IntPtr, ByVal
invert as Boolean) As Integer
End Function

3. Call the API using the target form's handle and TRUE. Assuming a Windows
Form class called "TargetForm":
Dim myTargetForm as New TargetForm
myTargetForm.Show ' shown modelessly

... other things happen...

FlashWindow(myTargetForm.Handle, True)


HTH,
