CallByName Button Caption

Can someone tell me how to use callbyname to set the caption on a button.  I want to pass in a string indicating the button name.

I found this, but I don't want to pass in the control, I want to pass in "Command1"

CallByName Command1, "Caption", VbLet, "OK"

Instead of VbLet, use CallType.Set:

CallByName(TextBox1, "Text", CallType.Set, "New Text")

You are still calling this with the control textbox1.  I want to call it with the control name "Textbox1"

Uh, that was an example - use your own control names, attribute names, and values.

Fraser_Admin is looking to use the name of the control, not a reference to the control.

The control name "Command1" and "Caption" property suggests VB6:

    Private Sub Command1_Click()
        CallByName Me.Controls("Command1"), "Caption", VbLet, "OK"
    End Sub

In VB.Net, you need a helper function to get the control reference from the control name like this:

    Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
        Dim c As Control = getControlByName("Button4")
        If Not (c Is Nothing) Then
            CallByName(c, "Text", CallType.Set, "OK")
        Else
            MsgBox(sender.name, MsgBoxStyle.Critical, "Control Not Found")
        End If
    End Sub

    Private Function getControlByName(ByVal controlName As String) As Control
        Dim i As Integer
        Dim ctl As Control

        controlName = controlName.ToLower
        For Each ctl In Me.Controls
            If ctl.Name.ToLower.Equals(controlName) Then
                Return ctl
            End If
        Next ctl
    End Function

you may also write a self callbyname sub like

private Function  myCallByName(byval ObjName as string,ByVal ProcName As String, ByVal UseCallType As CallType,  ByVal ParamArrayArgs() As Object )As Object

 Dim i As Integer
        Dim ctl As Control

        controlName = controlName.ToLower
        For Each ctl In Me.Controls
            If ctl.Name.ToLower.Equals(ObjName.toLower) Then
                exit for
            End If
        Next ctl
        If ctl.Name.ToLower.Equals(controlName.toLower) Then
           return CallByName(ctl,ProcName,UseCallType,ParamArrayArgs)
        else
           return nothing
        end if
end sub
