data combo boxes

Hello,

I was wondering how you can autofill a data combo box in VB 6. So if a user clicks on the combo box and they start typing it will automatically go to the selections typed in. Example: A user is looking in the combo box for a value of 'RGK' and they type in 'R' it will go to the R's and then if they hit 'G' it will go to 'RG's and so on. I have writen code for regular combo boxes but have not found a way to do it with datacombo's. Pleas help!

Thanks
