My text messsage is not visible during my program works

Question

I have write a programm, to write a file format in an other.
The files are so big that the programm work very long. So I made a text message  that show the program is still working.
In the beginning was working well. But now the text messages is no longer displayed.
I have no idea what the problem is.
some code:
int CVICALLBACK ReadCallback (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
int iConfiguration;
switch (event)
case EVENT_COMMIT:
SetCtrlAttribute (panelHandle, PANEL_TXTMSG_Load, ATTR_VISIBLE, 1);
GetCtrlVal (panelHandle, PANEL_Dataset_Conf, &iConfiguration);
Function_Worker(iConfiguration);
SetCtrlAttribute (panelHandle, PANEL_TXTMSG_Load, ATTR_VISIBLE, 0);
break;
case EVENT_LEFT_CLICK:
break;
return 0;
The function_worker does made nothing with the GUI but it works with a DLL. Is this a problem?
Do you have any ideas?

Somewhat more elaborate I'd suggest to modify your code as follows:
case EVENT_COMMIT:
    SetCtrlAttribute (panelHandle, PANEL_TXTMSG_Load, ATTR_VISIBLE, 1);
    ProcessDrawEvents ();
    GetCtrlVal (panelHandle, PANEL_Dataset_Conf, &iConfiguration);
    Function_Worker(iConfiguration);
    SetCtrlAttribute (panelHandle, PANEL_TXTMSG_Load, ATTR_VISIBLE, 0);
    break;
