I am trying to cast a string into an object (which is a parameter of a procedure). I also tried Ctype but it didn't work.
Public Sub procName(lbl1 as Label, lbl2 as Label, lbl3 as Label) 'suppose I have 10 labels
'long code here
for i as integer = 1 to 3
dim xL as label = DirectCast(Controls("lbl" & i.ToString), Label)
xL.text = i.Tostring 'I get the error here
next
End Sub
The error is:
Object reference not set to an instance of an object.
DirectCast(Controls("lbl" & i.ToString), Label)
is giving out a null value (or nothing)
What does Controls("lbl" & i.ToString)
return? is it of type label?
I don't have VB installed, so I cannot verify the following code:
For i as integer = 1 to 3
For Each acontrol As Control In Controls
If acontrol.Name = "lbl" & i.ToString Then
xL.text = i.Tostring
End If
Next
Next
