- Hello All,
-
- I am still having problems with the WinFileDlg API function
- and would like to solicite some information. In general,
- what I am trying to do is use the WinFileDlg function to
- return a path\filename of a file selected to be opened in
- the default OPEN style dialog box. The following section of
- code has not entirely worked:
-
- #define INCL_PM
- #define INCL_DOSFILEMGR
- #define INCL_DOSERRORS
- #define INCL_WINSTDDLG
- #define INCL_WINSTDFILE
- #define INCL_WIN
- #define INCL_DOSMEMMGR
- #define INCL_DOSQUEUES
- #define INCL_DOSSEMAPHORES
- #define INCL_DEV
- #include "V_PLOT_2.h"
-
-
- APIRET open_file(HFILE *fptr,HWND hWndOwner)
- {
- CHAR buffer[4];
- APIRET Dlgrc;
- FILEDLG Dlgdat;
- ULONG OpenAction;
- strcpy(buffer,"*.*");Dlgdat.cbSize=sizeof(FILEDLG);
- Dlgdat.fl= FDS_CENTER| FDS_OPEN_DIALOG
- FDS_PRELOAD_VOLINFO;
- Dlgdat.pszTitle=(PSZ)NULL;
- Dlgdat.pszIType=(PSZ)NULL;
- Dlgdat.pszOKButton=(PSZ)NULL;
- /* Dlgdat.pfnDlgProc=(PFNWP)NULL;
- Dlgdat.hMod=(HMODULE)NULL;*/
- Dlgdat.usDlgId=(USHORT)0;
- Dlgdat.pszIType=(PSZ)NULL;
- Dlgdat.papszITypeList=(PAPSZ)NULL;
- Dlgdat.pszIDrive=(PSZ)NULL;
- Dlgdat.papszIDriveList=(PAPSZ)NULL;
- WinFileDlg(HWND_DESKTOP,hWndOwner,&Dlgdat);
- Dlgrc=DosOpen(Dlgdat.szFullFile , fptr , &OpenAction
- ,0,0,OPEN_ACTION_FAIL_IF_NEW,
- OPEN_SHARE_DENYREADWRITE|OPEN_ACCESS_READONLY,0);
- return(Dlgrc);
- }
-
-
- This code will compile properly but die at the WinFileDlg
- call with a protection violation. If prior to the WinFileDlg
- call the Dlgdat.pfnDlgProc and Dlgdat.hMod variables are set
- to NULL (for example in IDBG) then the dialog procedure
- appears to work fine. If the comments are removed from the
- "open_file" section of code so that the Dlgdat.pfnDlgProc
- and Dlgdat.hMod variables are set to NULL prior to
- compilation, then the compiler dies with the following
- error:
-
- Invocation of <NMAKE.EXE> begins
- Invocation string: /f V_PLOT_2.MAK

- Will a CSD update fix this problem? I'm open to suggestions.
