Need help with windows app functions in C

In summary, the conversation is about using a function in a Windows application. The person has experience with creating dropdown lists and dialog boxes, but is unsure how to incorporate a function into the application. They mention wanting to display the value of the function in a dialog box and are open to using either C or C++ versions. It is suggested to convert the result into a string and use SetWindowText() or MessageBox. A resource for samples is also provided.

Hello folks,

Ok, I've been doing windows application tutorials, and I can make a mean dropdown list and dialog box, but I have no idea how to get the windows app to use a function. Say I just want a dialog box to pop up and use the function:

int myFunction ()
{
int i = 1;

return i;
}

to display the value of i in the dialog box. How do I do that, or something similar?
C or C++ versions are both acceptable.

It depends on the GUI toolkit.
Normally you convert the result into a string and then call something like SetwindowText() for the edit box.

Take a look here for samples http://www.functionx.com/visualc/

Right. I ended up converting it to a string and using MessageBox. Problem solved.
