I need to get the hWnd of a Forms 2.0 textbox.

The hWnd needs to work with the GetScrollPos API and similar functions.

I've tried the Setfocus/Getfocus method, but the hWnd I get doesn't work with the API.

The textbox is located in a picturebox on the form.

Any suggestions?

You can't get a Form 2.0 object's hwnd easily...

I think this is because of that:  The use of these Microsoft Forms components in your own compiled applications, such as those written with Microsoft Visual C++ and Microsoft Visual Basic, is not recommended or supported. These controls were designed and tested to work exclusively within Microsoft Office and its Visual Basic for Applications environment.

Hmm I tried to enumerate all child windows, but then I looked it with the Spy++ and "forms 2.0 textbox" doesn't even appear as a window...

Does this mean it doesn't have a hWnd?

Hmm...thanks for the help.  Do you know of any better unicode-aware plain-text textboxes?

Here is an example of how to "extend" a label to display unicode: http://www.vbforums.com/attachment.php?s=&postid=1380475 
I think you can do the same with a textbox...

Unfortunatly, that kind of "extending" is just changing character sets--I need full unicode functionality, as there are generally multiple character sets being displayed at the same time.

unicode-aware plain-text textboxes:
Depends on desired platform. If you need it to work on Win98 as well as NT/2000/XP you should look at RichEdit. Excellent freeware control available at http://www.mvps.org/emorcillo/vb6/controls/ctl_riched.msi I've been using it for over a year and it works great. For more info about Unicode controls see http://www.cyberactivex.com/UnicodeTutorialVb.htm

By the way I think Forms 2.0 TextBox is a windowless control thus the reason why you can't get a hWnd.

Thanks.  I ended up going with the RichEdit control.  Points to both of you for your timely help!
