Please help me out. I stuck at this point.
Any help would be greatly appreciated.

If you're using MFC, call the function AfxInitRichEdit() during application initialization.

Problem with CRebar ans REBANDINFO. Impossible to retrieve the lpText

Hello,

I have written a function to retrieve a band in CRebar by the text used with the AddBar function
like this

MainFrame->m_wndReBar.AddBar(WndBarMIL,"myText")

When I use my function FindToolbar (see below), the REBARBANDINFO.lpText is always NULL?
Actually, I use VS2008 with Windows XP. I can't remember if this function that I have written many years ago has never worked or if it's a new bug...

Thanks

BOOL CMyApp::FindToolbar(CString nom)

CMainFrame *MainFrame=(CMainFrame *)theApp.m_pMainWnd;
CReBarCtrl& ReBarCtl=MainFrame->m_wndReBar.GetReBarCtrl();
UINT i=0;
REBARBANDINFO bandinfo;
int j=ReBarCtl.GetBandCount();
while (i<rebarctl.getbandcount())> char textinfo[80];
bandinfo.cbSize=sizeof(REBARBANDINFO);
bandinfo.fMask=RBBIM_TEXT|RBBIM_CHILD;
bandinfo.lpText=textinfo;
bandinfo.cch=80;
ReBarCtl.GetBandInfo(i,&bandinfo);
if (strcmp(bandinfo.lpText,nom)==0) break;
else i++;
}
if (i->ReBarCtl.GetBandCount()) return(TRUE);
else return(FALSE);
}

How do you mean 'always NULL'? Does the ReBarCtl.GetBandInfo(i,&bandinfo); call modify the lpText member?

In fact, bandinfo.lpText is a null string (the first byte is equal to 0) ?

Probably no, but just to be sure...does anything change if you declare your textInfo array as TCHAR instead of char? So i mean, instead of char textinfo[80];, TCHAR textinfo[80];. Another question, is 80 characters enough? Could it be that you are specifying a not big enough buffer?

No change with TCHAR and 80 is more than necessary...

I will appreciate an other idea...

I don't know about it in VS2008, but I tested it in the Microsoft's ControlSpy tool and it is working.

I have received a mail where you talk about the hwndChild.

This pointer stays to NULL...

Effectively with control spy, I have the good lpText (Planets...). But I have no idea why my function doesn't work...

From your previous reply, I think, the window handle is not getting because the index might be wrong. When using ControlSpy, you can see that window handle become NULL when you give wrong index.

Can you debug step by step and trace the values?

That would be called a wizard.

Do a search for Property Page, Property Sheet, or for MCF, CPropertyPage / CPropertySheet.

Good luck,

~~May be SetWindowPos() can help? You can make use of the "insert-after" parameter.~~

Thought it was "back-n-forth".

Then you can use SetWindowPos. First of all you need to create them as "Modaless" dialogs. Which can be created using "Create" call rather than using "DoModal". Then you can simply call SetWidowPos and pass the other CDialog's pointer as the first parameter. It gets shuffled by that. You need to do it vice-versa in the other dialog. So that it works both ways.
