How to open a default fil by using the CFileDialog class I open the dialog box like this . I want to keep one file as default selection CFileDialog dlg(TRUE,"bmp",NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,"Only BMP (*.bmp)|*.bmp|"); dlg.DoModal (); Vikas Amin Embin Technology Bombay vikas.amin@embin.com

I need to open a file named "1.bmp" located as "c:\1.bmp" but i get assertion for invalid address ASSERT(AfxIsValidAddress(m_ofn.lpstrFile, m_ofn.nMaxFile)); My code is somthing like this :--------
CFileDialog dlg(TRUE,"bmp",NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,"Only BMP (*.bmp)|*.bmp|"); dlg.m_ofn.lpstrFile=TEXT("c:\\1.bmp"); dlg.DoModal ();Vikas Amin Embin Technology Bombay vikas.amin@embin.com -

sorry (error), now try with this:
TCHAR str[100]=TEXT("c:\\1.bmp"); dlg.m_ofn.lpstrFile=str;Have a nice code day ;)sorry there is some problem in the given code also some assertion at ASSERT(m_hFile != (UINT)hFileNull); I thing will have to go through the sturctre method i found some links will try from it http://eatworms.swmed.edu/~boris/B\_Player/VideoWnd.cpp http://www.codeproject.com/dialog/remove\_filters.asp Why simpe things are done so complicated in VC++ Vikas Amin Embin Technology Bombay vikas.amin@embin.com

I don't know, it is strange! :( A good thing could be add the flag OFN_FILEMUSTEXIST here: CFileDialog dlg(TRUE,"bmp",NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,"Only BMP (*.bmp)|*.bmp|"); So you are sure that the file exist. And I don't like very much ...,"Only BMP (*.bmp)|*.bmp|" I prefere ...,"Only BMP (*.bmp)|*.bmp||" Let me know Have a nice code day ;)

That is what the third parameter of
CFileDialog's constructor is for.vikas amin wrote:

Then why bother with
CFileDialogif you already know the name of the file? Also, the filter should end with two ‘|’ characters.

If
lpstrFileis assigned a non-NULLvalue, so mustnMaxFilealso be used to indicate the size of the buffer pointed to bylpstrFile. Why do it this way, however, when the constructor already has provisions for such?
