Problem with CallByname

Hi all,

I am facing one problem with callbyName. I am facing one problem, instead
of describing this I am pasting this code. I wanted to know is there any
other way to avoid this error and make generalized functions.

Please see the code.

Regards,

Kishor



Module Module1

Sub Main()

Dim pp1 As String = "Kishor"

Dim pp2 As String = "Ashish"

Dim pp3 As String = "Darshan"

Dim ppx1() As String = {"Kishor", "Rajeev", "Sonia"}

Dim ppx2() As String = {"Varsa", "Jassi", "Dahi bada"}

Dim ppx3() As String = {"MPK", "QSQT", "HAHK", "K3g", "PYTKK"}

Dim oc As New mycls()

'CallByName(oc, "TwoSingleParam", CallType.Method, pp1, pp2)

'CallByName(oc, "TwoArrayParam", CallType.Method, ppx1, ppx2)

'CallByName(oc, "OneSingleParam", CallType.Method, pp1)

CallByName(oc, "OneArrayParam", CallType.Method, ppx2)

'CallByName(oc, "ThreeArrayParam", CallType.Method, ppx1, ppx2, ppx3)

End Sub

Public Class mycls

Public Sub TwoSingleParam(ByVal p1 As String, ByVal p2 As String)

MsgBox(p1 & "..........." & p2)

End Sub

Public Sub TwoArrayParam(ByVal p1() As String, ByVal p2() As String)

Dim i As Integer

For i = 0 To UBound(p1)

MsgBox(p1(i) & " " & p2(i))

Next

End Sub

Public Sub OneSingleParam(ByVal p1 As String)

MsgBox(p1)

End Sub

Public Sub OneArrayParam(ByRef p1() As String)

Dim i As Integer

For i = 0 To UBound(p1)

MsgBox(p1(i))

Next

End Sub

Public Sub OneArrayParamxx(ByRef p1 As String, ByRef p2 As String,
ByRef p3 As String)

MsgBox(p1 & "" & p2 & "" & p3)

End Sub

Public Sub ThreeArrayParam(ByVal p1() As String, ByVal p2() As
String, ByVal p3() As String)

Dim i As Integer

MsgBox("chal gaya 1a")

For i = 0 To UBound(p1)

MsgBox(p1(i))

Next

For i = 0 To UBound(p2)

MsgBox(p2(i))

Next

For i = 0 To UBound(p3)

MsgBox(p3(i))

Next

End Sub

End Class

End Module

Hi Kishor,

I presume the commented out CallByNames give you errors.

The fourth parameter of CallByName is
ByVal ParamArrayArgs() As Object

This means that your parameters must be bundled up together in an Object
array.

CallByName (oc, "WhateverParam", CallType.Method, _
New Object() { --the parameters go here-- })

Regards,
Fergus
