how to generalize a command in Module to be called in different forms

Hi,
I am new to Visual basic and trying to write a program where I am writing a public subroutine in module and calling it in MDI and other MDI child forms. But the problem is, how should I make it general so that same subroutine can be used in different forms. For example the command: Form1.Picture1.cls
For the other form this command would be Form2.Picture1.cls. Please tell me how to generalize such commands.
Thanks in advance.

You would pass the object or form as a parameter
In your module

Code:

---

Public Sub ClearPicture(PictureBox as Picture)
PictureBox.Cls
End Sub

---

or

Code:

---

Public Sub ClearPicture(TheForm as Form)
TheForm.Picture1.Cls
End Sub

---

In your form code you would use

Code:

---

ClearPicture Picture1

---

or

Code:

---

ClearPicture Me

---

Of course neither of these would make any sense in the example you gave as you could simply use

Code:

---

Picture1.cls

---

in your form code rather than calling a separate sub for such a simple method.

In general however you should never make a specific reference to a form from a module or other form and instead you should pass the form or control to be used as a parameter so that the module can work with any form rather than being locked into a form by a specific name.
