DOCUMENT:Q189616 11-AUG-1998 [vbwin] TITLE :BUG: DateTimePicker Overrides ALT+F4 Key Combination PRODUCT :Microsoft Visual Basic for Windows PROD/VER: OPER/SYS:WINDOWS KEYWORDS: ====================================================================== --------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, version 6.0 --------------------------------------------------------------------- SYMPTOMS ======== When a DateTimePicker (DTPicker) control has focus, the ALT+F4 key combination does not work. If focus is moved to another control such as a TextBox, the ALT+F4 keystroke behaves normally. RESOLUTION ========== Utilizing either the KeyDown or KeyUp event of the DTPicker control, you can manually watch for the ALT+F4 keystroke combination and take the appropriate action, such as closing the application. STATUS ====== Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available. MORE INFORMATION ================ Steps to Reproduce Behavior --------------------------- 1. Create a new Standard EXE project. Form1 is created by default. 2. Choose Components from the Project menu and add a reference to "Microsoft Windows Common Controls-2". 3. Add a DTPicker control to Form1. 4. Add a TextBox Control to Form1. 5. Run the sample application. 6. Put focus on the DTPicker control if it doesn't have focus already. 7. Press the ALT+F4 keys. Note that the form does not close. 8. Move focus to the TextBox. 9. Press the ALT+F4 keys. The form closes as expected. 10. To workaround this behavior, paste the following code into Form1's code window: Private Sub DTPicker1_KeyDown(KeyCode As Integer, Shift As Integer) ' Check for Alt and F4 keystrokes If (Shift And vbAltMask) And (KeyCode = vbKeyF4) Then ' Unload the application Unload Me End If End Sub 11. Repeat steps 5 – 7 and note that the form closes as expected.
