Avoiding the default behaviour

[GrigoreDolghin]

Hello, All.

I am brand new to Visual Basic, and I came from Visual FoxPro. Sincerely, I miss the OOP orientation I have there. I have a lot of questions for you, guys.

Question no. 1:

How can I stop the default behaviour of a control? What I mean: for example, if the user clicks on the right-upper corner of the main form, I want the main form to show a messagebox to confirm the closing, and if the user respond 'Yes', it's ok, but if the user respond 'No', I want to stop the UNLOAD event of the form. Is there a way to do this?

For example, the question no. 2:

How can I create a menu with Alt+letter?


Thank you in advance.

Answer no. 1: ;-)
I snippet code below from my app. I have a MDIForm which will ask users if they click on menu Exit or the little 'x' on the top right corner :

Private Sub MDIForm_Unload(Cancel As Integer)

If MsgBox("Are you sure you want to exit?", _
vbQuestion + vbYesNo, &quot;Confirm Exit Application&quot <> vbYes Then Cancel = True

End Sub

Notice every form_unload procedure has 'Cancel As Integer' option. If you don't want to close the form, just set the Cancel value

2. :
Use '&amp;' following by the letter to create a shortcut key.
Ie : E&amp;xit
User can access it by pressing ALT + X.

The QueryUnload event is somewhat more appropriate to perform this task, as it offers the opportunity to check why the form unloads.

Private Sub Form_QueryUnload(cancel As Integer, unloadmode As Integer)

where unloadmode can, amongst others, take the following values:

vbFormControlMenu: The user chose the Close command (X button) from the Control Menu.
vbFormCode: The Unload statement is invoked from code.

As stated in an above reply, set the cancel argument to True if you want to stop the closing process _________________________________

Hello,

2. :
Use '&amp;' following by the letter to create a shortcut key.
Ie : E&amp;xit
User can access it by pressing ALT + X.

Sorry to bother again. It didn't work. The letter x is underscored, but can be accessed only if the menu is open. Otherwise not. It does not have the same behaviour as CTRL+X, for example. Any thoughts?
