I haven't time to set up the code you sent, but if I understand what you
are trying to show, add one line of code to the start of the click
method of the toolbar button, before your messagebox:
_Screen.ActiveForm.ActiveControl.SetFocus()

there's a very easy way to get around the problem with the toolbar
not receiving focus. I believe you merely reset focus to the current
control.
I'm not sure what you're saying.
Try this:
Create a toolbar class with one command button on it. In that command
button's Click() event method, put the following code:
MESSAGEBOX("Saving data, then quitting.")
WAIT "" TIMEOUT 3
_SCREEN.ActiveForm.Release()
Then create a form as follows:
Add a property to the form called oBar and set it to .NULL.
Add a textbox and a command button to the form. Make sure TabIndex of
the textbox is 1 and the button is 2.
In the Valid() event method of the textbox, put the following code:
IF "invalid" $ LOWER(THIS.Value)
RETURN .F.
ELSE
RETURN .T.
ENDIF
In Form.Init():
LOCAL oToolBar
oToolBar = NEWOBJECT("MyToolBarClass","MyToolBar.vcx")
THISFORM.oBar = oToolBar
THISFORM.oBar.Visible = .T.
In Form. Destroy():
THISFORM.oBar.Release()
THISFORM.oBar = .NULL.
Now run the form. See the toolbar and form appear.
In the textbox, type "invalid" and hit the TAB key. Notice you can't
leave the textbox.
Now, click the button on the toolbar. Watch the messagebox tell you
that your invalid data is being saved. Click OK on the messagebox,
then wait 3 seconds and watch the form and toolbar disappear.
Remember, this is about using Valid() to prevent invalid data from
being entered.
Yes, in the click of the toolbar button you could call code to check
the validity of the data in the textbox and reset focus to that
control if it doesn't pass. But if you're going to do that, you might
as well just have all of your validity tests called just before you
execute your save method and return .F. while displaying a helpful
explanation of the problem and how to fix it. Then you don't have to
mess around putting code into every Valid() method.
The only reason this wouldn't be better in most cases is if you are
binding data to controls, which, IMO, is not a good idea.
VFP has all kinds of RAD stuff, but often, RAD is BAD design. :)
