FIX: DHTML Scriptlet Method Fails on 1,143rd Invocation (261959)


The information in this article applies to:

  • Microsoft Internet Explorer (Programming) 5
  • Microsoft Internet Explorer (Programming) 5.01
This article was previously published under Q261959

SYMPTOMS

When you access a DHTML scriptlet for the 1,143rd time, you receive the error message:
Object does not support this property or method.

RESOLUTION

For Microsoft JScript, wrap calls to the offending method inside of a try/catch block. For Microsoft Visual Basic Script (VBScript), use On Error Resume Next. After the 1,143rd call, the method should work again, so all you need to do is suppress the error once.

STATUS

This bug was corrected in Internet Explorer 5.5.
