各位大哥,小妹今有一关于EditView的难题，帮个忙吧？

我想在以EditView为基类的窗口上显示一个.txt文本，不知道怎么显示好，速度还能快？
谢谢！

EditView::OnRButtonDown()
{
HANDLE hFile;
hFile = CreateFile( "C:\\MyDocument\\Test.txt", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
DWORD dwFileLen = GetFileSize( hFile, NULL );
DWORD dwRead;
char* pBuffer = new char[dwFileLen + 1];
VERIFY( ReadFile( hFile, pBuffer, dwFileLen, &dwRead, NULL) );
pBuffer[dwFileLen] = '\0';
CString sContent = pBuffer;
delete pBuffer;
SetWindowText(sContent);
}

对不住，上面有错！这样比较好：void CTestView::OnRButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
HANDLE hFile;
CFileDialog dlg( TRUE, TEXT("TXT"), NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, TEXT("文本文件(*.txt)|*.txt|所有文件(*.*)|*.*||"), this);

UpdateData();
if ( dlg.DoModal() == IDOK )
{
CString m_sOpenFile = dlg.GetPathName();
hFile = CreateFile( m_sOpenFile, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
if ( hFile == INVALID_HANDLE_VALUE )
{
MessageBox( "Cannot open file!", NULL, MB_OK|MB_ICONSTOP );
return;
}
DWORD dwFileLen = GetFileSize( hFile, NULL );
DWORD dwRead;
char* pBuffer = new char[dwFileLen + 1];
if ( pBuffer == NULL )
{
MessageBox("Malloc failed!");
return;
}

VERIFY( ReadFile( hFile, pBuffer, dwFileLen, &dwRead, NULL) );
pBuffer[dwFileLen] = '\0';
CString sContent = pBuffer;
SetWindowText(sContent);
delete pBuffer;
CloseHandle(hFile);
}
}

谢谢你，你帮了我一个很大的忙。真的十分感谢！
还想问你一下，如果我要在显示的文档中查找一个串，应该怎么写？
