OPENFILENAME

How to make a buffer in this case. Is there something like Space(n) in VB in C++.

Code:

---

OPENFILENAME op;
op.lStructSize  = sizeof(op);
op.hwndOwner  = hDlg;
op.nMaxFile  = 256; //something is wrong here
char a[255]; //something is wrong here
op.lpstrFile  = a; //something is wrong here
op.Flags  = OFN_CREATEPROMPT;
GetOpenFileName(&op);

---

The Fileopen dialog is looking like !#$@!@#!!# ,i can't see the file names.

Use:

Code:

---

OPENFILENAME op;
char a[256];

op.lStructSize  = sizeof(OPENFILENAME);
op.hwndOwner  = hDlg;
op.nMaxFile  = sizeof(a);
op.lpstrFile  = a;
op.Flags  = OFN_CREATEPROMPT;
GetOpenFileName(&op);

---

...instead. It's not too different, but it's what was in the PSDK. Anyway, just using char a[256] allocates the buffer for you (it's full of random data).

No Use.
The files in the fileopen dialog stil look like :
"ÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌ..."

Proble Solved.
I found this code on the i-net.Although i don't fully understand it , it works great.

Code:

---

#include <memory.h>
#define FILENAMESIZE        512
...
OPENFILENAME        ofn;
BOOL                b = FALSE;
char *szFullPathName;
        lstrcpy(szFullPathName,"");
        memset(&ofn,0,sizeof(OPENFILENAME));
        ofn.lStructSize = sizeof(OPENFILENAME);
        ofn.hwndOwner = hDlg;
        ofn.nFilterIndex = 1;
        ofn.lpstrFile = szFullPathName;
        ofn.nMaxFile = FILENAMESIZE;
        ofn.lpstrDefExt = "txt";
b = GetOpenFileName(&ofn);

---

I just get the warning that the variable szFullPathName is not initialized.How to initialize it.
I tried this,it works but later i get an illegal operation when i want to save a file.

Code:

---

TCHAR *szFullPathName;
szFullPathName = new TCHAR[512];

---

Is this OK or i need to initialize it in some other way.
