Hello all,

I'm having trouble with MDI child and a dialog form. The problem details are listed below:

1. One MDI Parent form (Form1) with a button on it (Button1).
2. One Child form of Form1 (name = Form2) with a button (Button2) and a textbox (text_box1).
3. Another form in the project (not child of Form1 and not MDI Parent) with name Form3. This form has also a button on it (Button3).

The application behaviour is as follows: the application starts with Form1. Clicking the Button1 will show Form2. Form2 correctly opened as a MDI child. Clicking the Button2 on the Form2 will show Form3 as dialog (Form3.ShowDialog() ). Clicking the Button3 on the Form3 need to do the magical thing - to set/change the text in the Form2's text_box1.

Tried various examples from this forum. Also followed a lot of examples from net. Nothing works. Tried to create a writable property in the Form2 class but calling it from the Form3 does nothing.

I tried to access the MDIchildren(ss) while ss loops in MDIchildrens array but I don't know how to access the label control inside the Form2 using this technique. Successfully changed the Form2 caption but no controls are available in VB intellisense - practically correct because VB don't know which form from array I'm referring to.

Could you please help me with this task? I'm not an experienced programmer but I don't want to skip the MDI section without this.

Regards,
Costin
