SYMPTOMS
========

When attempting to add a Form to a Visual Basic 5.0 project through the
IDTExtensibility model with VBComponents' Add method and passing
vbext_ct_MSForm, you get Run-time error '-2147467259 (800004005)':

  "System Error &h80004005(-2147467259). Unspecified error"

CAUSE

Visual Basic 5.0 does not support Forms3 designers, enum member vbext_ct_MSForm
is not valid.

RESOLUTION
==========

Use VBComponents' AddFromTemplate method. See the MORE INFORMATION Section of
this article.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the

Steps to Reproduce Problem
--------------------------

1. Start a New AddIn Project in Visual Basic 5.0.

2. Add the following line to the Private Sub OKButton_Click() in frmAddIn:

        VBInstance.VBProjects(1).VBComponents.Add (vbext_ct_MSForm)

3. Type "ADDTOINI" in the Immediate (debug) window and press the ENTER key.

4. Press the F5 key to run the project.

5. Start another instance of Visual Basic with a new standard EXE project*.

6. Under Add-Ins menu, select Add-In Manager, and then select My AddIn from the
  list.

7. Under Add-Ins menu, select My AddIn item.

8. Click OK on the Add-In Form. You will get:

  Run-time error '-2147467259 (800004005)': System Error
  &h80004005(-2147467259). Unspecified error.

9. Add a new form to the add-in project and save it in the 'Template' folder
  under Visual Basic folder as Form1.frm (for example, 'C:\Program
  Files\DevStudio\VB\Template', and then remove the form from the project.

10. Change the code:

        VBInstance.VBProjects(1).VBComponents.Add (vbext_ct_MSForm)

  in step 6 to:

        VBInstance.VBProjects(1).VBComponents.AddFromTemplate _
        ("C:\Program Files\DevStudio\VB\Template\Form1.frm")

11. Repeat steps 3 through 8. This time a form should be added to your project
  each time you click OK.

* If your project does not have a form, you will get 'Run-time error #9,
subscript out of range.'
