FIX: Failed to Mark Safe for Scripting Using Visual Basic PDW

• Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, version 6.0
  on the following platforms: Win95, Win98

SYMPTOMS

When an ActiveX control is marked as Safe for Scripting and Safe for Initialization when packaging it using the Package and Deployment Wizard (PDW), depending on your security settings for unsafe controls, Internet Explorer may still identify the ActiveX control as unsafe, or it may display an "Object Required" error.

CAUSE

The ActiveX control is not marked as Safe for Scripting and Safe for Initialization in spite of choosing these options when packaging the control using the Visual Basic 6.0 Package and Deployment Wizard.

This is because the [AddToRegistry] section is missing from the INF file generated by the Visual Basic 6.0 PDW, and this section usually contains the registry entries that mark the controls as safe.

RESOLUTION

You can manually add the [AddToRegistry] section in your INF file by following the steps listed below.

1. Create your ActiveX Control.



2. Package your control using the Package and Deployment Wizard.



3. Before you deploy the package, go to the folder for that package in Windows Explorer



4. There should be a support directory under that package. Open the Xxx.inf file under this Support directory with Notepad.



5. Paste the following code at the end of the file.

   
   [AddToRegistry]
   HKLM,"SOFTWARE\Classes\CLSID\{04CD5348-D028-11D2-82A6-00C04FB9D847}\Implemented Categories\{7DD95802-9882-11CF-9FA9-00AA006C42C4}"
   HKLM,"SOFTWARE\Classes\CLSID\{04CD5348-D028-11D2-82A6-00C04FB9D847}\Implemented Categories\{7DD95801-9882-11CF-9FA9-00AA006C42C4}" 




6. Save the file with the same name.



7. Run the .bat file in the Support folder, which is created by the PDW. This bat file will re-create your .cab file with the new changes.



8. Now you can use the PDW to deploy the package to the appropriate Web server location.

Steps to Reproduce Behavior

1. Create a simple ActiveX Control with at least one method or property.



2. Package it using PDW with the Internet Package option.



3. Set it as Safe for Scripting and Safe for Initialization in the PDW.



4. Deploy the Package to Web Server using the PDW.



5. From the Tools menu, click Internet Options. Click the Security tab. Change the following settings:



• Enable - download unsigned ActiveX Controls



• Enable - initialize and script ActiveX control mark for safe



• Prompt - initialize and script ActiveX control not mark for safe



6. Insert your control in your HTML page with an Object tag and set the codebase point to your .cab file. Script your control by setting/getting the property or calling its methods in the window onload event



7. From your client browser, navigate to your HTML page.



8. You will be prompted with the message that the control is not safe for scripting and initialization even though your security settings are set to enable for scriting and initialization safe controls. This shows that your control has not been marked safe as expected.
