RichEdit control breaks when call GetSel()

[ahoodin7]

<<Windows XP PRO MSVC 6.0 Pentium II 866 512 MB RAM>>

I am using a richedit control in my project.


code:-------------------------------------------------------------------------

void CRichTextEdtDlg::OnChangeRichedit()
{
long top=0, bot=0;
CHARRANGE cr;
if (m_fileloaded == true)
{
m_cRichEdt.GetSel(top,bot);
//....................error is in above code.
}
}
-------------------------------------------------------------------------------


I get a First-chance exception in AerProgram.exe (NTDLL.DLL): 0xC0000005: Access Violation in the GetSel() member function.

WINCTRL4.CPP:


code:-------------------------------------------------------------------------
void CRichEditCtrl::GetSel(long& nStartChar, long& nEndChar) const
{
ASSERT:IsWindow(m_hWnd));
CHARRANGE cr;
::SendMessage(m_hWnd, EM_EXGETSEL, 0, (LPARAM)&cr);
nStartChar = cr.cpMin;
nEndChar = cr.cpMax;
}
-------------------------------------------------------------------------------


SendMessage is blowing up. Why would SendMessage Blow up in a RichEdit control?

Also could it be that I somehow have the wrong version of riched32.dll?

Looks interesting, but could you step the with debugger into function GetSel and see what is exactlly the line where you get error?

Ion,

I have done this and this is the line that I got the error:

::SendMessage(m_hWnd, EM_EXGETSEL, 0, (LPARAM)&cr);

does that help?

Looks strange to me. I'll try this code later.
