There's really no such thing. Do you mean a thread with a message pump?

The project I'm working on requires to open a bitmap image from a location, display it and then save the image at another location.

In this project I use a variable in OnFileSave As Dlg as OPENFILENAME type.

But, I have already used the same variable during file open dialog as a CString type.

The problem is: I need to use the same variable for both the dialogs.

raviteja2020 wrote:

Plzz suggest a variable type that has the features of both CString and OPENFILENAME or any other alternate solution.

raviteja2020 wrote:

Now the problem is, I would like to declare a public variable so that it can do the work of both the variable types.
So I need a variable type as a combination of CString and OPENFILENAME.

void CSockDlg::OnFileSaveAs(HWND hWnd)
{
     OPENFILENAME ofn;
     TCHAR szPath[MAX_PATH];
     TCHAR szFile[MAX_PATH];
     ZeroMemory( &ofn, sizeof(ofn) );
     m_imgName.lStructSize = sizeof(ofn);

     szFile[0] = '\0';
     ofn.hwndOwner = hWnd;
     ofn.lpstrFile = szFile;
     ofn.nMaxFile = sizeof(szFile)/sizeof(szFile[0]);
     ofn.lpstrInitialDir = szPath;
     if ( GetSaveFileName( &ofn ) == TRUE )
     {
       // here set properly m_imgName
       // BTW: why don't you used CFileDialog instead of GetSaveFileName?
     }
     else
     {
     }
}

Here I've declared the variable again in th OnFileSaveAs() so that my project runs temporarily.
I'll have to remove the declaration from the dialog and have to declare a public variable.

same variable

int x = 5;
  
void main( void )
{
    int x = 10;
    cout << x; // what do you suppose this prints?
}
