Getting my form values to the next form

[andycharger]

I have a form which we shall call frm1.

I have a combobox that populates correctly from my database. When my users click on an item in the list and press select, I want to open another form, frm2, pass it the selectedValue from my combobox on frm1 and do another search.

 

How do I get the value to the next form (frm2)?

I know the Selected Value is correct because i built a messagebox to tel lme the value when the button is pressed.

 

Any ideas?

Create an overload constructor in Form2 that accepts that selected-value.

[andycharger]

How?

 

Can you provide some example code to create an overload constructor?

 

Basically here is my code:

 

frm1:

 

Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
       Dim PassVal As New Frm2()

       intPassedVal = ComboBox1.SelectedValue
              PassVal.Show()

end sub

 

then frm2 has this line in initializecomponent

TextBox2.Text = Frm1.intPassedVal

 

this just leaves me with a blank textbox.

On my side... I use the Session object which is rather more secure and faster.

You might try to work with overload but the Session object worked fine for me.

 

Session.Add(name,value);

Session[name] = value; // Doesn't work if it's not existent

Arch4ngel - he did mention a form and post this in the windows forms forum - perhaps session isn't going to be the best solution here.

This thread in the tutor's corner may be of some help.

My problem is the opposite of andycharger... Say frm1 generates 5 numbers. To add a new number, frm2.showDialog() is fired. He can pick from some more numbers on this form, frm2. When he finds the one he wants, he clicks OK button.

 

So with this example, how could i send back the number the user picks from frm2 back to the main form, frm1?

Create some public properties in your second form and access these when you return to the first form.

as I said in another post, to pass values between 2 or more forms, I create a module and I declare those public Variables, classes etc in that Module . I can access them from any other form in my project . ;)

You can also access a public variable without creating a module

In Form1: Public Shared publicInfo(20) As String can be accessed by any form as Form1.publicInfo(0), Form1.publicInfo(1), etc.

 

I personally prefer arrays as they can pass almost anything between forms.
