FormClosingEvent

[h s n]

I have File-Exit Menu. In this menu I want to invoke FormClosingEvent. Please tell me how can call that event from From File-Exit Menu. I dont know what to write in enum CloseReason. private void FileExit_Click(object sender, EventArgs e) { //here i want to call FormClosing event } private void MainForm_FormClosing(object sender, FormClosingEventArgs e) { if (dirty == true) { DialogResult res = SaveDialog(); if (res == DialogResult.Yes) { SaveFile(); e.Cancel = false; } if (res == DialogResult.No) { e.Cancel = false; } if (res == DialogResult.Cancel) { e.Cancel = true; } } }

Call Close method of your main form.

Just call Close on your File Exit handler. It will try to close the form, raising the Closing event in the process. If nothing cancels the closing, then you get the Closed event. You don't have to call your Closing event handler manually.

I think you can send the win32AI message "WM_CLOSE" when the button is clicked like a function in win32 SDK "SendMessage()" function: like this: // define [DllImport("User32.dll")] public static extern IntPtr FindWindow(String lpClassName, String lpWindowName); [DllImport("User32.dll")] static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow); [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)] static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam); const int WM_LBUTTONDOWN = 0x201; const int WM_LBUTTONUP = 0x0202; // sample, u should use spy++ to find windows class name and control class name IntPtr hwndWin = FindWindow("TfrmMain", "window title"); if (hwndWin.Equals(IntPtr.Zero) == false) { IntPtr hwndBtn = FindWindowEx(hwndWin, IntPtr.Zero, "TButton", "control text"); if (hwndBtn.Equals(IntPtr.Zero) == false) { SendMessage(hwndBtn, WM_LBUTTONDOWN, IntPtr.Zero, IntPtr.Zero); SendMessage(hwndBtn, WM_LBUTTONUP, IntPtr.Zero, IntPtr.Zero); } }
