FIX: Hide Event Doesn't Fire Correctly in Internet Explorer 4.0

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a new ActiveX DLL project.
2. From the Project properties, General, change threading model to be "Apartment Threaded."
3. Create a procedure to write debug messages to a file in your project directory. Cut and paste the following code into your UserDocument:

         Sub OutputDebug(iStr As String)
             Dim H As Integer
   
             H = FreeFile
             Open App.Path + "\" + App.EXEName + "_Debug.TXT" For Append As #H
             Print #H, iStr
             Close #H
         End Sub
   						

4. Add the following code to the Show and Hide events of your UserDocument:

         Private Sub UserDocument_Hide()
             OutputDebug "UserDocument_Hide"
         End Sub
   
         Private Sub UserDocument_Show()
             OutputDebug "UserDocument_Show"
         End Sub
   						

5. Save your project.
6. Compile the ActiveX DLL. Go into the Project Properties, Component and set Binary Compatibility to your ActiveX DLL.
7. Save your project again.
8. From Internet Explorer 4.0, navigate to .VBD file for your project. Wait for your UserDocument to display.
9. From Internet Explorer 4.0, navigate to a new location such as www.microsoft.com.
10. Exit Internet Explorer 4.0.
11. Examine the PROJNAME_debug.txt file in your project directory. Note that there is no Hide event message in the file. This indicates that the Hide event was never fired.
