Another test:
If I remove from RC this object
CONTROL "", 101, "TWBrowse", 0 | WS_CHILD | WS_VISIBLE, 6, 9, 266, 287
It works!

What happens?

I think it's likely that if you have a custom control in a resource you'd need to define and use it. Similar situation happened to me in the past when I was testing Xbrowse.

This morning this problem appears in a real project.
The error is present in a real project and in this little sample too
I have a lot of dialogs full of TWBrowse objects.
In the same project other dialogs containing "TWBrowse" objects work fine.
This morning something has changed compared to yesterday.

hua and Enrico,

Thanks very much!

too many "wild" copy and paste!

For user defined controls, like TXBrowse, TWBrowse, etc. it is a must to REDEFINE them, or Windows will not know how to create them.

I often use two or three browses, inter-related, in a dialog with no problem.

Uwe,

Once the user defined class has been registered, then Windows can create the dialogs even if the controls are not redefined

Also to me there is this error but only I use olbx ( wbrowse)
If I not define the xbrowse it not make error
perhaps there is a bug or limitation of this class ( wbrowse)
