Hello Guys, I have created a UI which connects to a hardware. I have started writing code for the hardware connection in my UI source code which can be seen below. As soon as the code executes the DAQmx configure code: -DAQmxCreateTask("Dev0-R",&taskHandle[0]);, the UI hangs and does not work further. Can anyone tell me what exactly is the problem. I an not connected to any hardware currently but creating a task command should work in my case. I am confused how to go further. Please help. // Code is shown below TaskHandle taskHandle[4];int main (int argc, char *argv[]){ int error = 0; /* initialize and load resources */ nullChk (InitCVIRTE (0, argv, 0)); errChk (panelHandle = LoadPanel (0, "PintschBamag.uir", PANEL)); errChk (AttributePanelHandle = LoadPanel (0, "PintschBamag.uir", ATTR_PANEL)); /* display the panel and run the user interface */ errChk (DisplayPanel (panelHandle)); /* Place for configuring the Hardware Channel connection*/ /*FOr the DAQMx*/ //char errBuff[2048]={'\0'}; /*********************************************/ // DAQmx Configure Code /*********************************************/ DAQmxCreateTask("Dev0-R",&taskHandle[0]); DAQmxCreateTask("Dev3-R",&taskHandle[1]); DAQmxCreateTask("Dev4-R",&taskHandle[2]); DAQmxCreateTask("Dev5-R",&taskHandle[3]); //code ends here Thanks,Raunak
