FIX: Error 405: "Unable to Show Modal Form Within this Context"

MORE INFORMATION

Steps to Reproduce Behavior

1. Create an ActiveX DLL in Visual Basic. Name the project "SrvDialog." Place the following code in Class1:

          Option Explicit
          Public Sub ShowDialog()
              Form2.Show 1
          End Sub
   
   					

2. Add a form to the project. Change the Name and Caption properties to "Form2." Place the following code on Form2:

          Option Explicit
          Private Sub Form_Click()
              Unload Me
          End Sub
   
   					

3. Compile the DLL.
4. Create a Standard EXE project in Visual Basic. Form1 is created by default. Make a reference to SrvDialog.DLL.
5. Change the BorderStyle property of Form1 to 3 (Fixed Dialog). Place a CommandButton on Form1, and place the following code on Form1:

          Option Explicit
          Private Sub Command1_Click()
          Dim x As New SrvDialog.Class1
             x.ShowDialog
             Set x = Nothing
          End Sub
   
   					

6. Run the client application. Click Command1.
7. Click Form2 to unload that form.
8. Click Command1 again and note that Error 405 occurs.
