Hi,

I have a function that will called :
BOOL BrowseForFile(CString *selName, CString defFilename)

I want to fill the selName with a OPENFILENAME value ofn.lpstrFile. How I can do this?

Usually, you'd use


BOOL BrowseForFile(CString *selName, CString defFilename)
{
OPENFILENAME ofn;

//...

GetOpenFileName(&ofn);

*selName = ofn.lpstrFile;

return bRC;
}

BTW, if you are *not* compiling as UNICODE, you'd have to convert to ANSI, i.e.

BOOL BrowseForFile(CString *selName, CString defFilename)
{
OPENFILENAME ofn;

//...

GetOpenFileName(&ofn);

char acAnsi[MAX_PATH];

wcstombs(acAnsi,ofn.lpstrFile,MAX_PATH);

*selName = acAnsi;

return bRC;
}

OPENFILENAME ofn;
GetOpenFileName(&ofn);
..

selName->Format("%s", ofn.lpstrFile);
Should also work.

Look at the BrowseForFile implementation at this page:
http://stuff.mit.edu/afs/sipb/project/ocaml/src/current/win32caml/menu.c

int BrowseForFile(char *fname,char *path)
{
        OPENFILENAME ofn;
        char *p,tmp[512],browsefor[512];
        int r;

        memset(tmp,0,sizeof(tmp));
        strncpy(tmp,fname,sizeof(tmp)-1);
        p = tmp;
        while (*p) {
                if (*p == '|')
                        *p = 0;
                p++;
        }
        memset(&ofn,0,sizeof(OPENFILENAME));
        ofn.lpstrFilter = tmp;
        ofn.nFilterIndex = 1;
        ofn.lStructSize = sizeof(OPENFILENAME);
        ofn.hwndOwner = hwndMain;
        ofn.hInstance = hInst;
        ofn.lpstrFilter = tmp;
        ofn.lpstrFile = path;
        wsprintf(browsefor,"Open %s",fname);
        ofn.lpstrTitle = browsefor;
        ofn.lpstrInitialDir = "c:\\";
        ofn.nMaxFile = MAX_PATH;
        ofn.Flags = OFN_PATHMUSTEXIST | OFN_NOCHANGEDIR | OFN_LONGNAMES |
                OFN_HIDEREADONLY |OFN_EXPLORER;
        r = GetOpenFileName(&ofn);
        if (r == 0)
                return 0;
        else return 1;
}
