Please help****Listindex & arrays

[SMDillon]

Hi guys,
I'm (unsucessfully) trying to create and populate a 2 dinensional array to store distances between two places.
I am then trying to use two list boxes to choose the start and end point of the journey. I cannot seem to get the listindex property to find the appropiate distance in the array. If anyone out there could help .....I would really appreciate it.
Cheers
Steven

Are you trying to populate the array from 2 listboxes? Or you're trying to read the values from the array?

Serge,
I'm trying to read my values from the array so that in list1/cbo1 there is alreay entires like London and list2/cbo2 will contain destination eg Paris, and the distance between the two (already loaded by the program in the array) will be displayed.
Cheers

How do you have those values in the array (i.e. do you have them as string like "London", Paris" etc)??? or do you actually save the position (ListIndex) of the item?

Serge,

I'm trying to save the position (lstIndex) of the item

[Serge]

So my guess, you save those indexes like this arrYourArray(0,0) would have value lets say 1 (London in first Listbox), but what's the value for the second Listbox arrMyArray(0,1)?

I think in this situation you better create a User Defined Datatype:


Private Type utTravel
iStart As Integer
iDestination As Integer
End Type

'----Then here you would declare your array of this user defined type:
Private tTravel(5) As utTravel


'-----Then lets say you want to select items in the Listboxes for the array element 2

List1.ListIndex = tTravel(2).iStart
List2.ListIndex = tTravel(2).iDestination



Whew, I hope I didn't confuse you that much.

Regards,

One thing that always gets me when I use ListBoxes and ComboBoxes with arrays is that I forget that ListBoxes are always zero-based while arrays do not have to be.
