hi all, is there a way to close msgbox programmatically?
(i need to drop a system "Pocket Pc Networking" msgbox...)
i've checked for "SetWindowsHookEx" but it seems to be absent from CF APIs...
any suggestion?

There may be a better way but this VB code works for me and should give you
a starter if your scenario is different...

' only ever 1 msgbox in our scenario
' else we have to check for title with GetWindowTextW
Dim hwnd As IntPtr
hwnd = Win32Api.FindWindow("Dialog", Nothing)
If IntPtr.op_Equality(hwnd, IntPtr.Zero) = False Then
Win32Api.PostMessage(hwnd, Win32Api.WM_CLOSE, 0, 0)
Win32Api.PostMessage(hwnd, Win32Api.WM_DESTROY, 0,
0)
End If

Cheers
Daniel

Wouldn't it be better to send WM_COMMAND with WPARAM set to IDOK or
IDCANCEL?

Dunno :-) It looks cleaner and less brutal (although I doubt it makes any
difference in the case of a message box)...

The question is will that work with YES|NO boxes etc? In my use case the
code wants to close any messagebox that happens to be up...

That would be IDYES - less chances to close someone else's box :-)

That's what I thought... there should be a IDDEFAULT for those bad devs
amongst us (that's me!) that want to close anybody's msgbox... Until then
I'll stick with WM_DESTROYing the universe... :-)

On a more serious note the code runs on our unit with no other apps [1], so
our approach is not the end of the world... Just added a comment to review
this if I ever move the code to a PocketPC...

Cheers
Daniel

your solution is right, because i don't know if this msgbox really
exists and if it's focused (maybe is under my app)...
but i have a problem: i try your code but i get a
"System.MissingMethodException" Exception on PostMessage

here's my code... (I could not find Win32Api namespace... is it any of
your classes?)

Declare Function PostMessage Lib "user32" (ByVal hWnd As IntPtr, ByVal
Msg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As
Integer

Const WM_CLOSE = &H10
Const WM_DESTROY = &H2

Dim hwnd As IntPtr

Dim a As Integer
a = PostMessage(hwnd, WM_CLOSE, 0, 0)
a = PostMessage(hwnd, WM_DESTROY, 0, 0)


what's wrong?
thank you!
matteo

PostMessage is in "coredll" on windows ce.

The Win32Api namespace is part of SDF which is found at http://opennetcf.org

Sorry about that. Win32Api is not part of SDF

Hi

<DllImport(DllName4)> _
Public Shared Function PostMessage(ByVal hWnd As IntPtr, ByVal wMsg As
Int32, ByVal wParam As Int32, ByVal lParam As Int32) As IntPtr
End Function

Cheers
