| re: Access Form Controls From Another Class?
The confusion lies in your naming convention.
Since frmMain uses camel notation, a C# developer using MS's conventions
will naturally assume that it's a member/local variable.
Anyways, you need to pass a reference to the form to the object that you
want to access its control.
public class MyControlAccessor
{
public MyControlAccessor(frmMain mainForm)
{
mainForm.myControl.....
}
}
