I'm using VB6. How do I get the data from all items in a listbox, whether they are selected or not? I have multi-select set to Extended and I have columns set at 0. This listbox is not bound to anything. I populate it with code using the AddItem method.

For i = 0 to Me.lstStartup.ListCount
     strStartup = strStartup & Me.lstStartup.ListIndex(i)
Next i

The above code doesn't seem to work.

You need to use the 'List' property instead of the ListIndex one. Also you need to go from zero to count-1

You might also want to separate each value with a new-line or a tab?


For i = 0 to Me.lstStartup.ListCount -1
     strStartup = strStartup & Me.lstStartup.List(i)
Next i

Listboxes in Access don't have a List property - you need to use Itemdata if referring to the bound column, or the Column property if referring to a different column in a multicolumn listbox

For i = 0 to Me.lstStartup.ListCount -1
     strStartup = strStartup & Me.lstStartup.ItemData(i)  'the bound column
Next i

For i = 0 to Me.lstStartup.ListCount -1
     strStartup = strStartup & Me.lstStartup.Column(i, 4)  'the fourth column
Next i

cquinn,

I'm actually using the listbox control in VB6. And the first solution posted is what I needed. I had actually tried to use "List" already but I was referencing the wrong listbox on my form, an empty one, and it appeared that my code wasn't working.

But I am noticing that there are some differences between listboxes in VB6 and Access. I'm more accustomed to using MS Access so the listbox in VB6 has me baffled.

Like, I don't understand VB6's implementation of columns. I'm just separating my "columns" with commas, each text value with a given amount of spaces, placing a comma after each value, and then using a fixed width font in my list box. This way I'm creating my own "columns". Also, I can use arrays to parse the data this way.

But I also wish I could have a scroll bar on the bottom (horizontal) so I could scroll over to see all the data.

I welcome any suggestions.

use the flex grid. see the semi-pseudo code.
with grid
.rows=0:.cols=0 'clearing the grid
.rows=2:.cols=4 'defining the grid size
'writing headings
.textmatrix(0,0)="SN": .textmatrix(0,1) = "name" .....
'writing data
do while not rs.eof
 .rows=.rows+1 'adding new row for each record from database
.textmatrix(.rows-1, 0) = SN ...........
 rs.moveNext
loop
....
...
end with
0

You should probably use a ListView control.
You can set the style to report and it is a control similar to the one on the right hand side of Windows Explorer.  When it is in report mode it is like the details view in windows explorer.  You can also define columns etc..
