Minimizing Event

[adiad]

I want to send the my application to the system tray
when the user press the minimize( _ ) of the form.
How can I catch this event ?


TIA,
Eddie.

i'm assuming you now how to send it to the tray, (if you dont, ask and ill post the code):

put in a timer with a rathedr fast interval(10 ro 20)

Static Ste&
if ste=me.windowstate then exit sub 'if it's already minimized, don't add another tray icon
Ste=Me.Windowstate
if me.windowstate=1 then 
'code for tray icon
end if

Thanks,

It's a good idea, but won't it overload the system ?

Maybe this can help:

WM_NCHITTEST
The WM_NCHITTEST message is sent to a window when the cursor moves, or when a mouse button is pressed or released. If the mouse is not captured, the message is sent to the window beneath the cursor. Otherwise, the message is sent to the window that has captured the mouse. 

WM_NCHITTEST 
xPos = LOWORD(lParam);  // horizontal position of cursor 
yPos = HIWORD(lParam);  // vertical position of cursor 
 
Parameters
xPos 
Value of the low-order word of lParam. Specifies the x-coordinate of the cursor. The coordinate is relative to the upper-left corner of the screen. 
yPos 
Value of the high-order word of lParam. Specifies the y-coordinate of the cursor. The coordinate is relative to the upper-left corner of the screen. 
Return Values
The return value of the DefWindowProc function is one of the following values, indicating the position of the cursor hot spot: 

Value Location of hot spot 
HTBORDER In the border of a window that does not have a sizing border 
HTBOTTOM In the lower horizontal border of a resizable window (the user can click the mouse to resize the window vertically) 
HTBOTTOMLEFT In the lower-left corner of a border of a resizable window (the user can click the mouse to resize the window diagonally) 
HTBOTTOMRIGHT In the lower-right corner of a border of a resizable window (the user can click the mouse to resize the window diagonally) 
HTCAPTION In a title bar 
HTCLIENT In a client area 
HTCLOSE In a close button 
HTERROR On the screen background or on a dividing line between windows (same as HTNOWHERE, except that the DefWindowProc function produces a system beep to indicate an error) 
HTGROWBOX In a size box (same as HTSIZE) 
HTHELP In a Help button 
HTHSCROLL In a horizontal scroll bar 
HTLEFT In the left border of a resizable window (the user can click the mouse to resize the window horizontally)

HTTOP In the upper horizontal border of a window 
HTTOPLEFT In the upper-left corner of a window border 
HTTOPRIGHT In the upper right corner of a window border 
HTTRANSPARENT In a window currently covered by another window in the same thread (the message will be sent to underlying windows in the same thread until one of them returns a code that is not HTTRANSPARENT) 
HTVSCROLL In the vertical scroll bar 
HTZOOM In a Maximize button

That would mean subclassing your Form ,which really isn't necessary in this case.
