The question is not very clear. Did you want the file dialog to show only files with .bin extension rather than all files?

Then you must pass a filter string as 5th parameter to the CFileDialog constructor (like "Binary files (*.bin)|*.bin|All files (*.*)|*.*||")

C++

// szFilters is a text string that includes two file name filters:
// "*.bin" for "Binary Files" and "*.*' for "All Files."
char CChildFrame::szFilters[]=
   "Binary Files (*.bin)|*.bin";

// Create an Open dialog; the default file name extension is ".bin".
CFileDialog CFiledlg (TRUE, "bin", "*.bin",
   OFN_FILEMUSTEXIST| OFN_HIDEREADONLY, szFilters, this);

// Display the file dialog. When user clicks OK, fileDlg.DoModal()
// returns IDOK
if( fileDlg.DoModal ()==IDOK )
{
     m_Input_File_Path=CFiledlg.GetPathName();
     char *file_path=new char[m_Input_File_Path.GetLength()+1];
     wcstombs(file_path,m_Input_File_Path,m_Input_File_Path.GetLength()+1);
     UpdateData(FALSE);
     delete[] file_path
}
