I observed that in OnItemExpanding for our tree, we have overridden your message handler. I did the same for OnDeletetreeItem and that fixed the problem.

Thanks.

We have not changed that part of code which you are referring to. My question is more of a wonder as to what would happen if you add that particular message map inside CXTShellTreeBase::OnDeleteTreeItem(). I compared the CXTShellTreeBase classes from 9.8.1 and 10.3.1 and figured that you added a new handler or was it moved from some other class? This part of code has definately changed file:

"c:\program files\codejock software\mfc\xtreme toolkitpro v10.3.1\source\controls\xtshelltreebase.cpp"

In the mean time I am looking at OnFolderExpanding. BTW this happens when i call

m_treeItms.DeleteAllItems(); in our code.

Thanks.

Hi,

I don't believe that in 9.81 you use lParam and it worked. All code of CXTShellTreeBase assumes that lParam is XT_TVITEMDATA

For example check OnFolderExpanding - how it will work if lParam not XT_TVITEMDATA.

Hello,

We are using XtremeToolkitPro library. We currently upgraded from 9.81 to 10.3.1, I noticed that a new function is added:

In xtshelltreebase.coo: CXTShellTreeBase::OnDeleteTreeItem.

It is giving us a crash at this particular position. I noted that inside this function you are assuming that lParam to be

XT_TVITEMDATA* lptvid, where as we are using it for our internal purposes. Is there a way to avoid this function being called when I call DeleteAllItems.

Kindly help,

Regards,

Sachin Modak.]]> Mon, 29 Jan 2007 18:17:20 +0000 http://forum.codejock.com/forum_posts.asp?TID=6259&PID=19845&title=cxtshelltreebaseondeletetreeitem#19845
