late binding

Hi,
Could you please explain why and where late binding is used in .net with a few examples?
Thanks

Hi

Simply don't late bind!

Calls on objects causes late binding that require extra work at runtime. Operators on objects causes late binding.

VB Code:

dim o,o1,o2 as object
o = o1 + o2 '' late binding

Option Strict ON will catch late binding

Hi,

I have the following function

[Highlight=VB]
Function standev(ByVal mean As Double, ByVal grades As Array) As Double
Dim x As Integer
Dim totaltop As Double = 0
For x = 0 To grades.Length - 1
totaltop = totaltop + (grades(x) - mean) * (grades(x) - mean)
Next
Return Math.Sqrt(totaltop / (grades.Length))
End Function
[vbcode

As you point out, with Option Strict On grades(x) is late binding.

However, if I cut and paste the entire sub code into a button_click event I have no problem.

Are you saying that it is the calling of the Sub which causes the problem? (Grades() is a form scope integer array).
