Hi
I am working in an SDI(formview) application.I had displayed the bitmaps on the screen through Open Dialog Box.Now the problem is that whenever i want to choose the bitmaps,i have to follow the number of paths to reach that specified folder in order to click on the actual bitmaps.Is it possible that whenever i click on the Open Dialog Box option,only the required folder open and all other paths vanish.The user should not be able to select any other bitmaps on the hard disk except the required one.

This is the work i have done.plz give me suggestions that what changes should i do in this....

public:CMyPicture m_ctrlBmp;
      CString m_strBmpFile;
      CString m_sBitmap;

void CPPCView::OnOpenbitmap()
{
static char BASED_CODE szFilter[]="Bitmap Files (*.bmp)|*.bmp||";
     CFileDialog filedlg(TRUE,".bmp",m_sBitmap,OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT,szFilter);
         
     if(filedlg.DoModal() == IDOK)
     {
          m_ctrlBmp.MoveWindow (-10,-10,790,610,true);
          m_strBmpFile = filedlg.GetPathName();      
     }
     if(!m_strBmpFile.IsEmpty())
     {
          m_pBmp = new CBitmap();      
HBITMAP hBitmap = (HBITMAP)LoadImage(AfxGetApp()->
   m_hInstance,m_strBmpFile,IMAGE_BITMAP,0,0,LR_DEFAULTSIZE|LR_LOADFROMFILE);
          if(hBitmap)
               m_pBmp->Attach(hBitmap);
                      m_ctrlBmp.SetBitmap(m_pBmp);
               m_ctrlBmp.ShowWindow (SW_SHOW);
                   
               }
     
     m_ctrlBmp.Invalidate();

}
waiting for comments.
thanks

i don't use MFC but i've used the open file common dialog via win32 api and i think i can help
inside the CFileDialog is a data member called m_ofn, this is of type OPENFILENAME
you can set some of these attributes before you get the path name
im assuming here that some of this already is initialized by the CFileDialog object, things such as lStructSize and others that you included in the constructor
lpstrTitle is one you can change, you set it to the title you want to appear on the dialog window
lpstrInitialDir is the one you're looking for, it sets the initial directory to choose from.

You can specify the directory that the open dialog starts in. You can also specify that it should only permit files in that directory and not any other.

I believe that is what you want. Just check out the methods for the open dialog, I am sure that one of the flags can be used to disallow changing directory.

Of course, for this to work you must set the directory to the correct one. The dialog box will by default use the process' current directory when opening the dialog box. If you want a different directory you must set the file path. You can also specify a default filename if you want.

There's a zillion various things you can set in that box, including show or not show hidden files, disallow opening of read-only files only allow filenames that already exist etc etc.
