[WN] Getting a Value from a Combo box

[Guest]

I'm not quite sure what the command or syntax is for getting a value from a Combo Box (e.g.  CmbClass) is, for example, if someone chose their class to be a warrior (in the combo box) then the class description would be blablabla. Thanks in advance.

ListIndex? And then make a validate that change the description using the Index of the item selected.

Not quite sure what you mean. What I'm trying to make is a class description box. Basically it reads off the combo box so if the combo box's option is set to "Warrior" then the description box will read off the classes.ini file and put the description in the box? How would I make it so that if the combo box says something the description box changes to that class' description?

In your cbo.SelectedIndexChanged grab the text you want from a file or whatever, depending on the ListIndex of the combo box.

Still not sure, I tried this for each classes (Dim'd the classes as Long aswell..In sub formload):

If cmbClass.ListIndex = Berserker Then
lblClassDesc.Caption = GetVar(App.Path & "\Data Files\classes.ini", "DESCRIPTIONS", "Berserker")

Did that for every class…nothing.

The listindex isn't "Berserker". Do it like this:

```
If cboClass.Listindex = #ClassNum# Then
lblClassDesc.Caption = GetVar...
```
Where #ClassNum# is the number of the class.

Ah I see, thanks Lightning.

No problem. Depending on how classes are indexed (whether they start from 1 or 0) you may need to add a +1 to cboClass.ListIndex if the classes are indexed from 1.

[Guest]

So then it would be

If cboClass.Listindex + 1= #ClassNum# Then

or

If cboClass.Listindex = #ClassNum# + 1 Then

?

[Yxxe]

If cboClass.Listindex + 1 = #ClassNum#

or

If cboClass.ListIndex = #ClassNum# - 1

[Guest]

Yeah I tried it, didn't work (and btw, its CmbClass)

[Yxxe]

Ok… try using '.Text = "Berserker"', or use your breakpoints to determine you index values..

[Guest]

Doesn't work either, get a Error 13: Type Mismatch on the line:

If cmbClass.text + 1 = "Berserker" Then

Try using your brain by removing the "+1".  :huh:

[Guest]

Hah sorry I'm tired…And it still doesn't work, the caption isn't changing, it isn't showing the descriptions at all.

The ListIndex returns the Index (number) of the item selected (starting from 0). So when that change, you have to change your Label/textbox, etc. using the data stored in your .ini file.

Ok I'll try and explain this a bit clearer so you can understand.

When you make a combo box you might add a list of names such as "Warrior, Ranger, Wizard"  In that list example the names are displayed top to bottom according to order, in this case the drop down box would look like

Warrior
Ranger
Wizard

The command cmboClass.ListIndex returns the index number that is selected.  Combo boxes are numbered starting from 0 to the end of their list.  The Above example has 3 items in its list, so the index are numbered as following

0
1
2

or

0 = Warrior
1 = Ranger
2 = Wizard

So the .ListIndex returns a number 0-2.  Sometimes the class.ini file will number the first class as class 0, if thats the case then everything is simple.  If however the classes are numbered from 1 and up then your need to -1 from the comparison.  Example would be

comboClass.ListIndex = (CLASS - 1)
