You need to export at least one function in order to have a lib file which is created.

Move Horizontal page breaks in Excel through VC++

Hello,
Does anybody know how to move horizontal pagebreak in excel through VC++ code?? I want to drag the first default horizontal pagebreak to new location.

Following is the code snippet..

HPageBreaks xlPageBreaks = m_xlSheet.GetHPageBreaks();
HPageBreak hb = xlPageBreaks.Get_Default(1);
COleVariant vCellTo = cellAt( 1, 62 ); // move pgebrk to this location
Range rangeDest = m_xlSheet.GetRange( vCellTo, vCellTo );
hb.SetRefLocation( rangeDest ) //

The method SetRefLocation() throws an exception.

Thanks,
Daryappa.

Are there standard Win32 functions that provide the same facilities as the System.Security.Cryptography class/namespace. I'm looking to canonicalize an XML document and generate a SHA1 hash key for the Inland Revenue.

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

Problem with CRebar ans REBANDINFO. Impossible to retrieve the lpText

HF3-Mar-09 23:50

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,
