Changing a Single value from another form

[tutuster]

Situation:

A form has various Single-typed values, the number of these values is dynamic, there might be only 1 or 1000 of these values.

The values are shown in the form on a label or some other component such as textbox. The click event of the component opens up another form, where the value can be changed by typing the new value to a txtbox and clicking a button

I would need to get some hints how to change this value from the other form, should I use the ByRef-statement? How can I change the value?

Short: How can I refer to a value on another form?

Resolved the issue by using objects/property.

However, that seems a bit clumsy, there must be a better way to do this, or is there?

Use custom events...

There is a FAQ that covers some of this.

If you pass a reference of the original form to the new form (or use the me.parentform member for windows opened modally) you can access all of the public properties that form has available. So if you made a public property for each of your values, and then gave the second form access to that object, then that would be an excellent solution.

Another option, like vlad mentioned, would be to use custom events on the child form, and handle those events on the parent form. You can then pass the new value in the event args variable. This is also a great solution.
