Winan,

Maybe someone with some VB knowledge might know better, but I think part of your problem is that you need to cast your oClass to a Form. I think in VB that means you need to use the CType() function, so something like this instead:

Dim DLLName As String = "Test"
Dim ClassName As String ="FrmInvoice"
Dim oClass As Object
Dim oDLL As Object

Dim oForm As Form

oDLL = System.Reflection.Assembly.LoadFrom(DLLName)
oClass = oDLL.CreateInstance(ClassName)
oForm = CType(oClass, Form)
oForm.Show()
