Creating a Status Callback Function
The following example is a simple status callback function. Register this
callback by using the
capSetCallbackOnStatus macro.
// StatusCallbackProc: status callback function
// hWnd: capture window handle
// nID: status code for the current status
// lpStatusText: status text string for the current status
//
LRESULT PASCAL StatusCallbackProc(HWND hWnd, int nID,
LPSTR lpStatusText)
{
if (!ghWndMain)
return FALSE;
if (nID == 0) { // Clear old status messages.
SetWindowText(ghWndMain, (LPSTR) gachAppName);
return (LRESULT) TRUE;
}
// Show the status ID and status text...
wsprintf(gachBuffer, "Status# %d: %s", nID, lpStatusText);
SetWindowText(ghWndMain, (LPSTR)gachBuffer);
return (LRESULT) TRUE;
