Controlling components on another form

[fergmj]

I have a program that has two forms. I have included the header files. The app compiles correctly and when I ShowModal Form2 all is good.

Form1 loads on start-up and in the Form1 OnCreate event handler, I want to set the properties of some components on Form2.

How do I do this?

Thanks

Form2->SomeComponent->ThingToDo();

I am already doing that:
Form3->Serial11->Baud = ini->ReadInteger("com 11", "Baud", 9600);

and I get an error at runtime

did you remember to put #include "Unit2.h" at the top of the calling form?

Unit2 of course being replaced by the form's header file name.

 

[fergmj]

Yes, I have included the header file for all of the additional forms.

Ahh.. so you already said that you did...

what is the error message that you're getting?

 

[fergmj]

I get an access violation error when I start the app.

try not sticking it in the OnCreate event, instead put it in the __fastcall TForm1::TForm1(TComponent* Owner) property. Then see if you get an error Cyprus
