Each contact should have a column for every survey, indicating whether or not the survey has been completed. However, this means I need to add columns to the database while the program is running. I tried the following code, which runs WITHOUT errors, but does not seem to actually add the column.

I am in need of adding arr of type label at run-time. I am making a program which will retrieve employee name from database in different label. On clicking each employee name (label) it will display all the information about that employee in a msgbox. I use the following code to create the label. Since the number of labels is not fixed I have used an array.
dim withevents lblArr() as Label 'declared in the class
In the subroutine(Form load):
for i as integer=0 to NoofEmployee-1
redim lblArr(NoofEmployee-1)
lblArr(i)=new Label
' I assigned all the necessary property like size location etc..
me.controls.add(lblArr(i))
next
I declared another subroutine:
private sub MyClick(sender as Object,e as EventArgs) **handles lblArr(0).click**
MsgBox("Hello")
end sub
The code doesn't compile since a subroutine doesn't.
