Communicating between 2 Forms

[FireBoy]

Hi, i've got 4 questions:

 

1. On form4 i've a button. How can I make that if I press it, the listbox on form2 refreshes?

 

2. How can i send some text to a textbox of form4 from form2?

 

3. I have made this:

 

Dim a As New Form4

a.Show()

 

All ok, but how can i disable switching through the forms? I want to disable it couse if form4 is active and the use press an button on form2 the prog crashes... so if form4 is on, i want it to have the focus all the time. I've tryed TopMos, but i can still switch between forms...

 

4. I've removed the box with icon and text from the taskbar, but now when i minimize my prog, this box is shown in the top of start. How can I completly deactivate it?

 

 

BIG THANX!!!!

 

 

!!! EDIT: I'm using Visual Basic .Net !!!

Have you looked here

3 . use ".Showdialog()" instead of ".Show()" in ur code

 

when I need to pass some values from a form to another, usually I use a module to declare Public classes and variables, and I work with those . Both forms will 'see' them.

usually I do it in this way.

 

Form2:

'declare a variable to hold Windows.Form

Public Shadows UpperForm as Form

 

Form1:

Dim f2 as New Form2

Form2.Show

Form2.UpperForm = Me

 

in Form2, if you want to enable the button of Form1:

UpperForm.btnClick.Enabled = False

 

'to read the value of component in Form1:

Messagebox.Show(UpperForm.txtName.text)
