Calling functions on the default form

Question

Hi I'm sure this is a simple question but I can't for the life of me remember how to do it! Say I have my main form of type Form1 and from that form I create another form of type Form2 how do I call public functions in Form1 from Form2? The problem is that I don't know what the instance of Form1 is called since it's created when the application starts. Normally if I create another form I set the name for example: Form2 foo = new Form2(); foo.publicFunction(bar); However with this scenario as I say I don't know how to refer to the default form! Many thanks Ian Atkinson

I've managed to fix this now I'll post the solution so it's archived. In the Program.cs file which launches the first form the default line reads as follows: Application.Run(new Form1()); What I did was set a static variable at the top of the Program class like this: public static Form1 mainForm; and then changed the run line to be as follows: Application.Run(mainForm); Functions on this form can then be called by referring to mainForm for example: Program.mainForm.publicFunction(); I'm sure there are neater ways (and I'd love to hear them) to do this but this does work!
