ok, thanks for all you who have put up with all my API questions
today....last one (besides my one about adding a Menu Item to the system menu
for all processes....)

I have the handle of a window, i get the icon, hide the window by using

ShowWindow(HandleHere, SW_HIDE)

and it hides the window, then i add its icon to the system tray. now (i
already added a handler for the notifyicon double click event) i want to
restore the window when its double-clicked. ive attempted

ShowWindow(HandleHere, SW_SHOW)

but that didnt work, neither did

ShowWindow(HandleHere, SW_SHOWMAXIMIZED)

nothing ive tried has worked....OpenIcon() hasnt worked either.....how can i
restore the window? thanks

I suggest to post the function declarations you are using.
 
sure, sorry, forgot to do that....


Private Declare Function ShowWindow Lib "user32" Alias "ShowWindow" (ByVal
hWnd As IntPtr, ByVal nCmdShow As Long) As Long

Const SW_HIDE As Integer = 0
Const SW_SHOWNORMAL As Integer = 1
Const SW_NORMAL As Integer = 1
Const SW_SHOWMINIMIZED As Integer = 2
Const SW_SHOWMAXIMIZED As Integer = 3
Const SW_MAXIMIZE As Integer = 3
Const SW_SHOWNOACTIVATE As Integer = 4
Const SW_SHOW As Integer = 5
Const SW_MINIMIZE As Integer = 6
Const SW_SHOWMINNOACTIVE As Integer = 7
Const SW_SHOWNA As Integer = 8
Const SW_RESTORE As Integer = 9
Const SW_SHOWDEFAULT As Integer = 10
Const SW_FORCEMINIMIZE As Integer = 11
Const SW_MAX As Integer = 11


then i tried this too

Dim x As New IntPtr(CInt(tray.Text))

ShowWindow(x.ToInt32, SW_SHOW)


thanks a ton for your help

Your declaration was wrong. Here's the corrected version:

\\\
Private Declare Function ShowWindow Lib "user32.dll" ( _
ByVal hWnd As IntPtr, _
ByVal nCmdShow As Int32 _
) As Boolean
///

When asking questions about p/invoke, always inclide the declarations you
are using because often declarations are incorrect and lead to problems.
