I encounter this error everytime I click the 'Close' cmdbutton on the first page or my Cbizobjmaintenanceform. But this error also occurred everytime I click the 'cmdCancelmaint' on the other pages. I compared everything with the sample ProjMgr. I found out that the difference is that I didn't set the data environment of my CListObj on the third page that I added. On the 3rd page is the CListObjEdit. After adding the data environment in the Builder window for CListObj, I was able to close my form properly without any error.

I suggest that this error can be added to the error handling chapter of the DEVGUIDE document. This may help other developers who are just starting to use the framework.

Thanks a lot for the information on Substring. This may really slow down the operation but our users really need this.

Thanks a lot.
