Capture text box LostFocus

I use Crescent text box controls in 16-bit VB 4.0.  I have some code behind the text boxes' LostFocus event that need to be executed (mostly data validation).  However, when I click on one of the menu itmes in MDIOnline form, the LostFocus event of currently selected text box did not get triggered.  I tried to use SendKeys "{Tab}" in menu item click event, but the LostFocus event still did not get fired.  Can somebody provide me with a pointer?  Thanks in advance.

First, you're never going to get the lost focus event to fire. I encounter the same problem about 10 months ago and spent almost 2 days chasing it.

My best advice is

1) move ALL validation code from ALL controls to a central SUB.

2) in each control's GotFocus event, set a global variable (of type control) to whatever control just got the focus.

3) In each control's Lost focus event, call the central sub.

Now here's the tricky part ... Since you're using Crescent's QuickPac controls (by the way I LOVE THOSE CONTROLS!) anyways, QuickPak has a control called CSForm. When you add CSForm to a form, you get a bunch of new events. The two events you're interested in are MenuBrowse and SysMenuClick.

In those two events, you also fire the Centralized SUB.

You may also want to take a look at the CtlNotify event. I played with it a bit, but to be honest, the danged thing fired too much, especially in an MDI environment.

Good luck.
