save content combobox

tankfrank35 · September 25th, 2007, 04:25 PM

Hello,

i'm new in vb and i like it a lot.
I made a small program as test for a bigger one later on with not to many script.
i have 3 comboboxes as an array. the content of the combobox is in an .dat file on the harddrive.
when the program opens, the data is loaded from the file to the comboboxes. no problem to add data(drivers in this case as string) to combobox and file.
removing data is a problem for me. I can remove it from the comboboxes (combo1(a).removeitem) but to remove it from the file is a problem.
I figured something out to solve this.
make a savebutton (or autosave) and when the program ends with the "output" command I clear the content of the .dat file en write the new data in it.
the new data should be the entire content of the combobox and here is the problem.
How is that content called so i can print it to the file?
its not combo1(a).text or combo1(a).listindex.

does somebody know how this is called and if it works the way i figured it out?

Hi there.. Don't have VB6 here, but don't you have a list property that you can iterate???

thx gbianchi for your reply,

the problem is that vb gives an error on "combo1.list" evrytime when i try to get the data out of it.

it says "argument not optional" with ",list" in the code highlighted.

yes.. you have to pass the index position to it ;)

try something like:

Code:

For i = 0 To Combo1.ListCount
    strText = Combo1.List(i)
Next i

fix that code to do what you need, but the idea is to iterate all the items in the combo...

Thx again, and guess what, i fixed it.

i did it like this:

Dim i As Integer
Dim nieuw As String
Open "c:\Documents and Settings\TankFrank\Mijn documenten\Mijn ontvangen bestanden\Frank\winkel.dat" For Output As #4
For i = 0 To Combo1(0).ListCount - 1
nieuw = Combo1(0).List(i)
Print #4, nieuw
Next
Close #4

thx for your help
