Joaquín M López Muñoz20-May-02 0:24 Joaquín M López Muñoz 20-May-02 0:24  MFC DLLs provide their own entry point, so you're not supposed to write one yourself. If you plan to write a DLL with MFC support, I'd suggest you start with a fresh MFC DLL created by the app wizard and then move your code there.

You should use this method only when the window has been created (i.e. if you do it right after creating the CDialog object, it will fail.)

Thats exactly my problem.I do it on OnInitDialog() and it failed.I wanna to write the username that login in computer in the caption place,So I think I have to do it in OnInitDialog(). Now how can I do it?

Just make sure you're doing it after calling the base class method CDialog:OnInitDialog.

I supposed that could be the problem, since otherwise it should work without a problem.

It doesn't matter whether you call SetWindowText() before or after the call to the base class. I guess his problem lies elsewhere Nish Regards, Nish Native CPian. Born and brought up on CP.

ON_UPDATE_COMMAND_UI_RANGE? 19-May-02 22:47 19-May-02 22:47  Hi, For a group of menu item, use the ON_UPDATE_COMMAND_UI_RANGE( id1, id2, memberFxn ) to update the menuitem status. But how to declare the memberFxn, try the void CMainFrame::OnUpdateMyMenuItem(UINT nID, CCmdUI* pCmdUI) { ... } and void CMainFrame::OnUpdateMyMenuItem(CCmdUI* pCmdUI, UINT nID) { ... } Both cannot work. (They will Cause Access voilation Error). Can someone help me? Thanks in advance. Best Regards, Wayne King Re: ON_UPDATE_COMMAND_UI_RANGE? Joaquín M López Muñoz19-May-02 23:02 Joaquín M López Muñoz 19-May-02 23:02  It should be void CMainFrame::OnUpdateMyMenuItem(CCmdUI* pCmdUI); The extra nID is not needed, as this information can be retrieved from the CCmdUI object itself. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo How do I link a 16-Bits DLL? mistika19-May-02 22:42 mistika 19-May-02 22:42  Could anyone tell me how to link a 16-Bits DLL in Visual C++ 6 using MFC? I need load a old DLL. I read about convert it to 32-Bits DLL, and seem very dificult, Is it absolutly necesary to do it? Thanks in advance! Re: How do I link a 16-Bits DLL? Joaquín M López Muñoz19-May-02 22:51 Joaquín M López Muñoz 19-May-02 22:51  If you've got the source code, I'd strongly recommend you rebuild for 32-bit. Otherwise, your only choice is to construct a so called thunk DLL that does the translation between 16- and 32-bit worlds. Thunks are a complex subject, and you might need to get some assistance to do one. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo how to expand one tree by sending message well2000com19-May-02 22:33 well2000com 19-May-02 22:33  I want to expand one tree's item (like IE) by sending message or by some other way, while I don't know which item it is but its full path(eg: c:\test) How can I do this? Thank you! Re: how to expand one tree by sending message Prem Kumar20-May-02 0:55 Prem Kumar 20-May-02 0:55  Compare against the Tree Items label and expand the mathing item by calling CTreeCtrl::Expand. Re: how to expand one tree by sending message well2000com20-May-02 14:41 well2000com 20-May-02 14:41  Prem: but there is a problem if two or more labels have the same name and if the there is many layers in the tree the search speed will very slow. thanks anyway.
