Using Option Explicit

[Todd_M]

How do you declare a varible such as X to be listed as public? If I code in:

Option Explicit
Public x as Integer

on one form, how do you get the value of X on another form? I thought if you Public a varible on one form, it see's it on every other form and module. Can someone explain this to me?

Form modules are class modules, so a global variable in a form can't be seen by other modules. If you want a variable that can be seen by multiple forms, declare it in a regular module.

Hope this helps,

So what your saying Russel is that you can only declare a global varible in a regular module, but not on a form? So why does VB allow you to make a public statement on a form, when it dosnt do anything?

Anyway, here's the scoop;

I have four checkboxes that are in one frame (Ive created an array). The X varible = the checkboxes index property. So if X=index in the Check1_Click event of a form, how does one get the value of X in another form to read the index property in this form??

The public variable in a form is very similar to a private variable in a form - it's a Form-Global variable (meaning it has scope in all of the events in the form). However, it can also be read by other forms / modules (as long as the form is open) by reading it like this:

Userform1.X

where X is your public form variable.

This isn't the best way to do this, but it will work. You can control who can set / retrieve your form variables using Property Let and Property Get. But if you're only using it for other forms to read, the above way should be good enough.

Hope this was clear,
