I suggest you do something like this:

1. Assign FormB to a custom property in FormA.
2. Make a custom method in FormB that will have the code for doing whatever needs doing. Say it's called DoAction().
3. FormA's button.click could call thisform.oForm.DoAction( passSomeParamter )

Even better, have a custom method in FormA called DoAction(), too. (Sounds like a subclassed form with two additional subclasses, if necessary, for formA and formB.) Then, the command button in formA would call FormA.DoAction(). This will will help centralize form level code so that it's easier to maintain.
