Multi select list box

[crewchiefpro6]

I am having trouble understanding the multi select listbox. Since I now need one I was wondering if there is an easy way to create one, I really do not want to just drop a class in, I want to understand the workings of one.

I downloaded a few classes as prg files, but I want to create one myself on a form.

The listbox control that comes with Visual FoxPro comes with the ability to do multiselect. Just set the multiselect property to 1. Mutliple items can be selected using the ctrl key and left mouse clicks (basic Windows conventions apply). Then loop through the items in the listbox and check their selected property to see which ones the user selected. There's an example of this in the VFP Help file under the "MultiSelect Property" topic.

Now, if what you wanted was to simulate checkboxes or something in order to show multiple selections, then there is FAQ I wrote that should help you understand the concept and code involved. Here's the link:

Thanks Craig,
I actually downloaded your code and was trying to transfer it to a form to make a class but was unabled to figure out the check marks next to the rows. Can't seem to figure out what you did to make them appear in a form without running the prg code.

Then loop through the items in the listbox and check their selected property to see which ones the user selected.

Just to clarify that. The Selected property is in fact an array. Each element in the array corresponds to one of the items in the list. The element is .T. if the item is selected, othewise it's .F.
