Minimize button code changes 1

[SmileeTiger]

Hi,

I am trying to have some extra events happen whenever a user presses the minimize button inside a window. What message handler does the minimize button use?

minimize button respond to WM_LBUTTONDOWN.
The owner window receive in this case message WM_COMMAND with wParam = SC_MINIMIZE. This messsage you can process in your WndProc. Be attentive, don't return 0 on responding to this message. If you want to send a message to a window to minimise, just call
ShowWindow(hWnd,SW_MINIMIZE); John Fill

OK.. so I have to add the handler for WM_ONLBUTTONDOWN right?

After doing so I end up with:
void CTmpDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/orcall default

CDialog::OnLButtonDown(nFlags, point);
}

How do I ensure that the user has clicked on the minimize button?

Am I going about this completly wrong?

Try some thing like it:
void CTmpDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
ShowWindow(SW_MINIMISE);
CDialog::OnLButtonDown(nFlags, point);
}

Actually that won't do at all.. this code will simply minimize the window whenever the user clicks anywhere in the dialog box with his left mouse button. What I want to do is have an extra evern happen whenever the user clicks the minimize button...

OK I almost have it working.. what I did was use OnSysCommand to take care of the calls.. however now I want to hide the task bar icon and it isn't working.. I think I need a handle to the taskbar but I am not sure how to det it.. any ideas?

void CTsuRenderCoreConsoleDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
if (nID == SC_MINIMIZE) // Decide if minimize state changed
{
this->ShowWindow( SW_HIDE ); //SHould hide the task bar icon here...
MessageBox("Min"
CDialog::OnSysCommand(nID, lParam);//Take careof the normal params
}
else if (nID == SC_RESTORE) {
//SHould show the task bar icon here...
MessageBox("Restore"
CDialog::OnSysCommand(nID, lParam);//Take careof the normal params
}
else
{
CDialog::OnSysCommand(nID, lParam);
}
}
