//cmd_id is the ID of A cmd used to edit text inside a non modal dialog box (handled by //NonModal_h)
//len is the lenght of the text inside the cmd. I've previously cheked that len!=0.
BOOL PutFileName(int cmd_id, DWORD len)
{
    char name[256];
    char tmpfilter[40];
    int i = 0;

    for(i=0; i<256; i++)
        name[i]=0;
    i=0;

    OPENFILENAME ofn;

    memset(&ofn,0,sizeof(ofn));
    ofn.lStructSize = sizeof(ofn);
    ofn.hInstance = GetModuleHandle(NULL);
    ofn.hwndOwner = GetActiveWindow();
    ofn.lpstrFile = name;
    ofn.nMaxFile = 256;
    ofn.lpstrTitle = "Save";
    ofn.nFilterIndex = 2;
    ofn.lpstrDefExt = "txt";
    strcpy(name,"*.txt");
    strcpy(tmpfilter,"All files,*.*,Text Files,*.txt");
    while(tmpfilter[i]) {
        if (tmpfilter[i] == ',')
            tmpfilter[i] = 0;
        i++;
    }
    tmpfilter[i++] = 0; tmpfilter[i++] = 0;
    ofn.Flags = 539678;
    ofn.lpstrFilter = tmpfilter;

    BOOL res= GetSaveFileName(&ofn);

    if(res!=0)
        {
        char* buffer;
        buffer = (char*)GlobalAlloc(GPTR, len + 1);

        UINT ta=GetDlgItemText(NonModal_h, cmd_id, buffer, len + 1);

        //modifica il create_always!
        HANDLE file= CreateFile(ofn.lpstrFile, GENERIC_WRITE | GENERIC_READ, FILE_SHARE_READ,
            NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_ARCHIVE, NULL);

        LPDWORD NumOfBytes;
        /*OVERLAPPED data;
        data.Offset=0;
        data.OffsetHigh=0;
        data.hEvent=NULL;*/
        BOOL err=WriteFile(file, buffer, len+1, NumOfBytes, NULL);
        if(err==0)
                                                                ErrorBox();

        err=CloseHandle(file);

        HGLOBAL fre=GlobalFree((HGLOBAL)buffer);
        }

return 0;
}

so... ErroBox() is a part of code that returns the messageBox with the extended error string. I've try a lot and finally seems that the error is inside the WriteFile function: "there is a wrong parameter...

plz help!

Send your source to bj_4paws@yahoo.com and I'll have look. Give me the lot, not just a sample. With a Windows program life is harder than usual!

thanx,

but I've found bug this morning; simply I'm still making a lot of chaos with new types, DWORD and Co.: I'm used to the old turbo c++ and to long, int... what's hell a LPDWROD!?:)

now no problem:)

thanx,
Matteo
