i entered the GetPane()， CWnd* CSplitterWnd::GetPane(int row, int col) const { ASSERT_VALID（this）; ... } the app stopped at here

i 've tried ,then i have no regret

i wrote the code in EVC++ 4.0, MFC，when i debug the code, the error occur at: CDisplayData* pDisplayData=(CDisplayData*)pMainFrame->m_wndSplitter.GetPane(1,0); i don't know how to solve it, please help :(( void CReadWriteData::DisplayAxisInfo() { ... CMainFrame* pMainFrame=((CMainFrame*)AfxGetApp()->m_pMainWnd); CDisplayData* pDisplayData=(CDisplayData*)pMainFrame->m_wndSplitter.GetPane(1,0); pDisplayData->m_xAxisCor.Format(_T("%f"),fValue); pDisplayData->UpdateData(FALSE); }

it is an good day :-D

CString::Format maybe a good choice,i'll try it tomorrow:)

i want to convert the interger to a binary string in EVC.so i use the '_itot'. UINT16 high16data = dwReadValue; CString high16string = _itot(high16data, high16string, 2); the error is:error C2664:'_itow':cannot convert parameter 2 from 'const unsigned short *' how can i convert the parameter?(i do want to use the CString type not the char[] as showed in MSDN). so how to do it? thanks for helping.

:) it works.it takes me about three hours to try to solve it. thank u very mnuch.

thank u, i've tried the Bram van Kampen's method,it works:)

my code:

#include "stdafx.h"
#include <stdio.h>
#include <fstream>

void CParamDisplay::OnParamOpen()
{
// TODO: Add your control notification handler code here
CFileDialog cfiledlg(TRUE, NULL, NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT
, "Text Files (*.txt)|*.txt|All Files (*.*)|*.*||", this);

if (IDOK == cfiledlg.DoModal())
{
	m\_filename = cfiledlg.GetPathName();
	UpdateData(FALSE);
	DisplayParam(m\_filename);
}	

}

BOOL CParamDisplay::DisplayParam(CString filename)
{
UINT sNum = 0;
CHAR paramId[MAX_BUF_SIZE] = _T("");
CHAR paramUnit[MAX_BUF_SIZE] = _T("");
FLOAT paramValue = 0;

FILE\* pFile = fopen (filename, "r");

if(pFile == NULL)
	return FALSE;

while(fscanf(pFile, "%d %s %s %f", sNum, paramId, paramUnit, paramValue) != EOF)
{
     ...
}

fclose(pFile);

return TRUE;

}

when i debug it, the app stopped at fscanf().and displayed:"Uhandled exception in XX.exe (MSVCRTD.DLL):0XC00000005:access violation".i can't fix it...(T_T)

IXMLDOMDocument *pDoc = NULL; BSTR bstr = NULL; ... bstr = filename.AllocSysString(); hr = pDoc->load (bstr, b_load); filename is a CString type,how can i slove this problem?

i difine a custom message(i want to post it to a driver) #define WM_INTERRUPT WM_USER+100 then i use it as a parameter in the function DeviceIoControl ... ULONG nBytesRead; if (! DeviceIoControl( m_hPCI9054, IOCTL_SET_NOTIFICATION_EVENT, &WM_INTERRUPT, sizeof(WM_INTERRUPT), NULL, 0, &nBytesRead, NULL ) ... it makes an error: ...'DeviceIoControl' : cannot convert parameter 3 from 'const int' to 'void *' how to fix it?

i 've tried ,then i have no regret

thanks for ue help nave, but yr code still have a little problem:)

if(lstrcmp(szProcessName, "smss.exe"))
_tprintf( TEXT("%s (PID: %u)\n"), szProcessName, processID );

that is: function lstrcmp(lpstring1, lpstring2),when lpstring1 equals lpstring2,the return value is zero.so if i need only see "smss.exe" on the screen,i should change it like this

if(!lstrcmp(szProcessName, "smss.exe"))
_tprintf( TEXT("%s (PID: %u)\n"), szProcessName, processID );

oh yea.. haha i must be looking like a fool now... i fix it thanks for yr help :)
