Could somebody please explain why this doesn't work!

I'm quite annoyed at the moment. This worked this morning, I swear, but now it doesn't. What is going on.

In one project, compiled as a DLL I have this code:

class cFormSFX:

Code:

---

Public Property Set TargetForm(frmNewValue As Object)

    If (TypeOf frmNewValue Is Form) Then
        MsgBox frmNewValue.Name
    End If
End Property

---

In a second project, compiled as an exe I have this code.

form Form1

Code:

---

Private mobjTest        As FormSFX.cFormSFX

Private Sub Form_Initialize()
    Set mobjTest = New cFormSFX
   
    Set mobjTest.TargetForm = me
End Sub

---

The typeof validation in the DLL fails, and I do not understand why. Can anyone help me?

How the heck were you able to display a messagebox from a DLL? Are there other components to the DLL you're not showing?

I also use a Msgbox in my dll, it works perfectly.

What do you mean by it doesn't work anymore? Any error message? Was your DLL still registered when it failed?

In the dll. It does not recognise the value in frmNewValue as a VB.Form object when I try and validate it in the Typeof statement. I have no idea why. Any ideas.

Never mind guys. It seems that I can't run 2 IDE's at once (don't see why not, it works fine apart from that stupid little error).
If I compiled the DLL it works perfectly, I just can't tweak things and test them as fast as I could with 2 IDE's. Alas, such is life. Thanks for the suggestions anyhow.

Hi,

Just on a side note ...

Using the TypeName() VB function gives you a text name of what the variable type is, which might be useful when the TypeOf operator doesnt seem to be working.

Just knowing what the actual variable type is in this kind of situation can often help you solve the problem and bypass all that confusion and frustration.
