Control Width setting Reg

I am not able to get u

i am creating the Form(Product Master)
To which the controls like label
and combo box will be added dynamically
based on the fields created in one master table.
for eg the table may contain fields like

Column datatype size
MixCode varchar 50
Ply varchar 20
ValueAddition varchar 100

i will fetch these names and add label and combo box (using control array )

i am able to add the controls--there is no issue in that

Now i want to make each combo of diff size based on its Fields size

Now all the controls seems to appear in same width .

I want to change each combo control of different width based on the datatype size

i can fetch the datasize but i dont know how to assign the width to combo bcoz the width of control ,it will be in pixels in VB form.

i can get the size of mixcode as varchar(50).if assign as such then the control's width becomes very tiny.

pls help me
