请教：为什么TAB上的控件不能赋值，请高手指点！

这是我的一个小程序，调试时一点“OK”按扭出现如下提示： NON-FATAL RUN-TIME ERROR:   "111.c", line 27, col 13, thread id 0x00000CA4:   Library function error (return value == -58 ). The control does not have a value
哪位大虾帮忙看下，万分感激！

代码如下：
#include <cvirte.h>               
#include <userint.h>
#include "111.h"
static int panelHandle;
int main (int argc, char *argv[])
{
        if (InitCVIRTE (0, argv, 0) == 0)
                return -1;        /* out of memory */
        if ((panelHandle = LoadPanel (0, "111.uir", PANEL)) < 0)
                return -1;
        DisplayPanel (panelHandle);
        RunUserInterface ();
        DiscardPanel (panelHandle);
        return 0;
}

int CVICALLBACK OkCallback (int panel, int control, int event,
                void *callbackData, int eventData1, int eventData2)
{
        switch (event)
        {
                case EVENT_COMMIT:
                                                                                                       
        //        SetActiveTabPage (panelHandle, PANEL_TAB,1 );
                        SetCtrlVal (panelHandle, TABPANEL_STRING, "SDFSDF");   

                        break;
        }
        return 0;
}

int CVICALLBACK QuitCallback (int panel, int control, int event,
                void *callbackData, int eventData1, int eventData2)
{
        switch (event)
        {
                case EVENT_COMMIT:
                        QuitUserInterface (0);
                        break;
        }
        return 0;
}
