Calling form functions from Class 1

[stillinlife101]

I have the function

public void FormLine(Point pt1, Point pt2) {}

that is declared in my main form. I want to call the function (i.e. in another class type frmMain.FormLine(params)) from another class, but it doesn't show up. How do I access those functions without making another instance of the form? It's not enough to make it static, it has to refer to the original instance of the form.

Thanks,

Dan

How are you declaring the variable of type frmMain? If you declare it as a Form, and not a frmMain, you'll never see your public methods/properties.

Thanks, I fixed it by passing a reference to the form to the function. It's the name form, so it's declared as an application, whatever that means.

That'll probably work.

Just also wanted to make sure you're not coming from a VB background, where there was an implicit variable created behind the scenes for each form. In .net, that doesn't happen, as forms are objects, and they obey all the object variable rules. It's as if you were saying

Textbox.Text = "somevalue";

when you should have been using an instance of Textbox. Common error.
