Little ComboBox trouble

Well, first of all Id like to say Im a newbie with VB, so this may seem like a stupid question to some of you, or maybe not. I really dont know. Anyway here I go:

I have this ComboBox that has different items on it (these items are movie titles). What I need is, that everytime I select a different movie, it has to appear the number on a Textbox.

I.e :
If I select V for Vendetta as my first movie the textbox has to show the number 1. Then If I change V for vendetta for another movie lets say Wedding Crashers the textbox has to show the number 2.

It has to happen everytime I select a different movie. . the textbox represents the number of different movies Im selecting..

I really dont know how to do this..at all!.. I need your help . please try to keep it simple cause as I already said before, Im a newbie at this :cool:

The simple way to do this is to put this in the Click event code:

Code:

---

textbox.text = combobox.listindex

---

And it will change the number in the textbox with each click.

Welcome to the forums:wave:

What I would suggest is to add a counter to your code, so each time you select a film you add 1 to the counter.

Code:

---

Dim ctr as integer

Private Sub Combo_Click()

 'your code  here

 ctr = ctr + 1

 'Add the total to your textbox
 Text1.Text = ctr

End Sub

I don't think this gives a total for the number of films selected which is what the op asked for.

To quote the OP:

"It has to happen everytime I select a different movie. . the textbox represents the number of different movies Im selecting.."

This could have multiple meanings:

1) Count
2) The unique number (index) of each entry.

Based on the other information that the OP supplied, I'd wager #2.

The meaning is..

1) Count

Well thanks to you, aikokid, I finally made it! ITs all good now...the thing is..I find myself with a new problem.. =(

Now I need..that ( on a different form) a textbox says the movies I selected.. If I selected wedding crashers and v for vendetta de textbox must show both of them..the textbox now represents the movies I already rented..can you help me with this please?. To me, it seems rather complicated.

PS: I know that If I name the form and then the control it will show the same as in the prebious form.

I.E .. Textbox1.

I accidentally posted it..sorry .. the last part was

I.e Textbox1.text= Form1.ComboBox1.SelectedItem

The only problem is that it only works for the movie that is actually selected (that would be the last one I chose) so It will only show one..not all the ones I chose...how do i do this?

Try this code:

Code:

---

Textbox1.Text = Textbox1.Text & " " & Form1.ComboBox1.SelectedItem

---

Or if the textbox is big enough and has the multiline property set to true try this:

Code:

---

Textbox1.Text = Textbox1.Text & vbcrlf & Form1.ComboBox1.SelectedItem

---

I havent tried that yet but IT sounds like it will work indeed.. The thing is . what IF the user selects more than 2 movies..?
If I use this
Textbox1.Text = Textbox1.Text & " " & Form1.ComboBox1.SelectedItem
Its only 2 movies right?.. Oh and . what is the value of the textbox1.text in this case?

Im using Select Case on the previous form so .. the form2.textbox1.text would be = to the Combobox.SelectedItem on the form 1 right? . thats what you mean?

If you already have movie A and movie B in the textbox and then the user selects movies C & D, do you want all 4 in the textbox or just C & D?

Code:

---

    Dim lngIndex As Long
   
    For lngIndex = 0 To List1.ListCount - 1
        If List1.Selected(lngIndex) Then
            Textbox1.Text = Textbox1.Text & List1.List(lngIndex) & vbCrLf
        End If
    Next

---

All 4 of them . . .If the user selects movie A. then the textbox must show the movie A .. and then selects a movie B then the textbox must show the movie A and B .. the same as C and D

Then see my post #5.

Post 5 ?..Textbox.text = Combobox.listindex ?

I get error If I use ..Textbox1.text = Form1.Combobox2.ListIndex (Form1. because Im writing this on the form2)

Aikokid, Im asking you.
If I use this Textbox1.Text = Textbox1.Text & " " & Form1.ComboBox1.SelectedItem

Then Textbox1.text = ? .. If I use Select Case X on my previous form and everytime I select a different movie I put Form2.Textbox1.Text = X and use the code you gave me . itll show the same movie cause everytime I select a different movie the Textbox1.text on form2 will be the same as the one I already selected...crap -_-..this is getting complicated hehe

Juan, Post what code you have so far and I will see if I can help. :)

I'm sorry, I meant #12.

Take a look at this quick example and see if this helps.

It looks like theres crossed wires because Juan Carlos's code is .Net. I have put an example of what i think you want. Its 2005.

Juan, are you using VB.Net?

Sorry Ive been absent for a while. had some stuff to do. I have VB 2005 Express Edition.

Aikokid I couldnt open your Text project. dont know why , But I could open the other one. and it is exactly what I needed!. thanks a lot!

user name (post 20) really understood what I needed. But ..is there any other way of doing it a little..simpler maybe?

Moved.

Don't use VbCrLf. This is legacy vb6. Use Environment.NewLine instead as this is the actual .NET command.

Juan, Are you having problems understanding the code because you wont get it much simpler than that for what you need, theres only 6 or 7 lines.
