Background output

[AndyHollywood]

Why would my program output to a text file when the window is in focus, but not when another window has the focus?

the following is in a dll and if the function that is giving me probs:

LRESULT CALLBACK KeyboardFunc (int nCode, WPARAM wParam, LPARAM lParam )
{
    HDC    hDC;
    //Timer Elements
    _ftime( &timebuffer );
    timeline = ctime( & ( timebuffer.time ) );
                        


    if ( nCode >= 0 ) {

        if ( nCode == HC_NOREMOVE )
            strcpy(szType, "NOT Removed from Queue");
        else
            strcpy(szType, "REMOVED from Queue                                             ");
        
        //strcpy(temp, keyType(wParam));
        if(pKB) //Output to txt File
            if (lParam < 0)
                fprintf(pKB, &quot;Key:%d,Up,%.19s.%hu %s&quot;,wParam,timeline, timebuffer.millitm, &timeline[20] );
            else
                fprintf(pKB, &quot;Key:%d,Down,%.19s.%hu %s&quot;,wParam,timeline, timebuffer.millitm, &timeline[20] );

        wsprintf((LPSTR)szFilterLine[KEYBOARDINDEX],
            &quot;KEYBOARD\tKey:%d\t%s&quot;,wParam,(LPSTR)szType);

        hDC = GetDC(hwndMain);
        TabbedTextOut(hDC, 1, nLineHeight * KEYBOARDINDEX,
            (LPSTR)szFilterLine[KEYBOARDINDEX],
            strlen(szFilterLine[KEYBOARDINDEX]), 0, NULL, 1);
        ReleaseDC(hwndMain, hDC);
   }
CallNextHookEx.
   return( CallNextHookEx(hhookHooks[KEYBOARDINDEX], nCode, wParam, lParam));
}

am i outputting to the text file properly?!

it paints the results in the window ok, but dosent output to the txt file?! why would this be?
