How would you ? You have to loop though a collection to populate it , i don't think there is another way.

you cant, you have to recurse through and add the items.  if you had the information in a database you can use the datacombo control though.

i think what you want to use is the listview control.  its like a listbox but it supports multi columns.  if this interests you let me know and i can post some code on how to use it.

It ain't that hard to create your own combobox, all you need is a simple textbox, a picturebox and the grid. You use the Line method to draw a pressed or unpressed button interface on the picturebox (you can not use a normal commandbutton because it will look terrible when it has the focus), in the MouseDown event draw a pressed button and in the MouseUp event draw a unpressed button. In the MouseUp event you also want to toggle the visibility of your grid. Voila! You have a combobox that has a grid as the dropdown control.

Here's the code I use to draw the button interface on the picturebox.

Public Sub DrawDown()

  'This will draw a pressed button interface
  'in the picButton picturebox, emulating a
  'real commandbutton
  picButton.Cls
  picButton.Line (0, 0)-(15, 16), vb3DShadow, B
  picButton.Line (5, 7)-Step(7, 0), vbBlack
  picButton.Line (6, 8)-Step(5, 0), vbBlack
  picButton.Line (7, 9)-Step(3, 0), vbBlack
  picButton.Line (8, 10)-Step(1, 0), vbBlack

End Sub

Public Sub DrawUp()

  'This will draw a unpressed button interface
  'in the picButton picturebox, emulating a
  'real commandbutton
  picButton.Cls
  picButton.Line (0, 0)-(0, 17), vbWhite
  picButton.Line (0, 0)-(15, 0), vb3DLight
  picButton.Line (0, 0)-(0, 16), vb3DLight
  picButton.Line (1, 15)-(15, 15), vb3DShadow
  picButton.Line (14, 1)-(14, 15), vb3DShadow
  picButton.Line (0, 16)-(15, 16), vbBlack
  picButton.Line (1, 1)-(14, 1), vbWhite
  picButton.Line (1, 1)-(1, 15), vbWhite
  picButton.Line (15, 0)-(15, 17), vbBlack
  picButton.Line (4, 6)-Step(7, 0), vbBlack
  picButton.Line (5, 7)-Step(5, 0), vbBlack
  picButton.Line (6, 8)-Step(3, 0), vbBlack
  picButton.Line (7, 9)-Step(1, 0), vbBlack

End Sub
