BUG: Cannot Use Out-Of-Proc Server Instantiated in OBJECT Tag

ID: Q183023


The information in this article applies to:
  • Microsoft Internet Explorer (Programming) versions 4.0, 4.01, 5.0


SYMPTOMS

Out-of-process (EXE) components do not work correctly when instantiated through an OBJECT tag in HTML under Internet Explorer 4.0x. Internet Explorer 4.0 appears to instantiate the component but when you access any property or method of the component from script, you get the following error message:

Object does not support this property or method


CAUSE

Internet Explorer does not correctly instantiate out-of-process components (EXEs).


RESOLUTION

If it is not possible to convert your application to an in-process component, there is a limited workaround. The workaround is to use VBScript's CreateObject function instead of the OBJECT tag. You supply the ProgID of your component to CreateObject instead of the CLSID required by the OBJECT tag. You can use CreateObject in an inline script as follows:


<SCRIPT LANGUAGE="VBSCRIPT">
    Dim MyComp
    Set MyComp = CreateObject("Project1.Class1")
</SCRIPT> 
Please be aware that the above work around has the following caveats:

  • Internet Explorer cannot download your component to the client's machine without an OBJECT tag. You can elect to use the OBJECT tag to perform the download and also do a CreateObject if your component will allow this.


  • You cannot get events from the component created with CreateObject.



STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.


MORE INFORMATION

Out-of-process (EXE) components do not work correctly when instantiated through an OBJECT tag in HTML under Internet Explorer.

Steps to Reproduce Behavior

  1. Build a Visual Basic 6.0 ActiveX EXE project. Make sure you have at least one property or method in your class.


  2. Use Package and Deployment Wizard to generate an Internet Package for your project.


  3. Modify the HTM file to add script that calls your property or method from the Window_OnLoad event.


  4. Run the HTM file in Internet Explorer.


RESULT: The following error message appears:
Object does not support this property or method.
