Question

My string comparison doesnt work.I tried compare,equals ,= and all of these methods doesnt work.
Here’s my code:

Dim activeChild2 = Me.ActiveMdiChild
    If TypeOf activeChild2 Is Window Then
        Dim activeChild As Window = Me.ActiveMdiChild
        If (Not activeChild Is Nothing) Then
            If activeChild.CTR_User.ToString = activeChild.User_name.ToString Then
                Call activeChild.Edition()

                Select Case Trim$(UCase(activeChild.Name))
                    Case "FRM_MISSION"
                      'treatment
                    Case "FRM_TACHE"
                        'treatment

                End Select
            Else
                MsgBox("Error modification!!!!", MsgBoxStyle.Critical)
            End If
        End If
    End If

The problem is in If activeChild.CTR_User.ToString = activeChild.User_name.ToString Then .In spite of having same string toto=toto the code always fires to the else clause and show me the msgbox

Why are you calling .ToString? Are activeChild.CTR_User and activeChild.User_name strings, or are they objects that you’re trying to compare?

If they’re objects, you can’t compare them with .ToString(), as it will be inaccurate. you should use something like activeChild.CTR_User.Equals(activeChild.User_name) or activeChild.CTR_User is activeChild.User_name. I can’t really give you specifics unless I know what types you’re working with.

Have you tried putting a breakpoint on it and checking the values manually within Visual Studio’s many debugging tools?
