Embedding CCJTreectrl in CTreeView

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi 
Has anyone tried using the treectrl in a ctreeview (or is this stupid?) 
I can use the CJ tree ctlr in my treeview with 
 CCJTreeCtrl* m_pTreeCtrl = (CCJTreeCtrl*) &GetTreeCtrl();
and it works fine until I try to use the extra functionality with 
 m_pTreeCtrl->EnableMultiSelect(TRUE);
at that point I get :
File: i386\chkesp.c
Line: 42
The value of ESP was not properly saved across a function call. [..]

I've tried switching to different calling conventions (__stdcall, __cdecl) with no effect.
Is it possible to embed a CJ tree ctrl in a tree view ?
Thanks Huw

	I reinstalled my OS, VC 6.0, Xtreme Toolkit 8.61 Pro, Platform SDK. I did a rebuild all on my program. I ran my program and got a similar error. On another machine, I don't get the error...not sure why, but the answer is in the differences. If I find out what is causing this, I'll let you know.

	Okay. In my particular case, I had copied the XT Pro dll from one machine to another and tried to run my program using that dll (wrong). I instead copied the dll which was built on the same machine, to my program's bin directory, ran the program, and the error went away. Hopefully this information will help you in some way. Tim

	This breaks the laws of C++. The object would have to be allocated as a "CCJTreeCtrl" in order to call methods that are *in* "CCJTreeCtrl". All you have done is cast a CTreeCtrl* to a CCJTreeCtrl, that does not automatically give you access to everything in CCJTreeCtrl. I would suggest you use CXTTreeView.
