Multithreading in multiple source files

[Kugelkopf]

Hello everyone!

I have read the topics about working with multiple source files and multithreading as well, however i cannot manage to make the two work in my project.

There is an example program about multithreading, with a counter.

When you start the program the counter starts as well and when you push a reset button it is set back to 0 and starts counting again. 

I would like to do this with another source file but on the same user interface. It other numeric on the UIR starts counting as well, however i cannot reset it back to 0. I would like to know where i went wrong. I would appreciate any help, but i just put here the whole project in a zip file.

Thank you in advance!

Hi,

The 1st counter thread has a counter variable named "counter" and the second thread has a counter variable named "numbering". If you haven't already noticed, you are resetting the value of only counter and not numbering.

int CVICALLBACK ResetCounter (int panel, int control, int event,
		void *callbackData, int eventData1, int eventData2)
{
	switch (event)
		{
		case EVENT_COMMIT:
			counter=0;
	SetCtrlVal (panelHandle, PANEL_NUMERIC, counter);
			break;
		}
	return 0;
}

Add numbering=0; in the above callback function. Another thing i have noticed is that , you are initiliasing the panelHandle in both files, which is not neccessary. Also its recommended to release the threads before you stop the program using quit callback.
