Error 80020101 while calling javascript function from Visual Basic

Hi Gurus,
I am facing problem while calling a javascript function from Visual basic. Basically my requirement is like this.

First I have to invoke a web page from visual basic and once it is called, I have to invoke javascript function in it. While debugging the code, I could see that the web page gets loaded successfully but the code gives error 80020101 when it executes the call to javascript function. Below is the code that I have used.

Dim oIE As Object
'Create the IE application object.
oIE = CreateObject("internetexplorer.application")
'Load the URL.
oIE.Navigate("http://xyz.net:8065/bc/bsp/crm_ic/default.htm?sap-client=220&sap-sessioncmd=open")
'Wait for the web page to load completely.
Do While (oIE.ReadyState <> 4)
Loop
'MsgBox(oIE.Document.frames.length)
Call oIE.Document.parentWindow.execScript("window.top.setProduct('1105206503')", "JavaScript")

I could successfully simulate the process by doing following steps -
1. Paste the URL in web brower and let the page load successfully.
2. Now paste the function in web browser like javascript:window.top.setProduct('1105206503')
By doing this, it calls the function successfully.

But when I am trying to execute this through VB code I get error 80020101.
I tried statements like -
Call oIE.Document.frames.execScript("window.top.setProduct('1105206503')", "JavaScript")
or
Call oIE.Document.frames(0).execScript("window.top.setProduct('1105206503')", "JavaScript")

but no use.

The statement MsgBox(oIE.Document.frames.length) returns 0 suggesting that there is only one frame on the page.

Help please.

Thanks,
Rahul.

Hi Master,

Thanks for the link. I checked it and tried few possibilities mentioned in it.

Today I started testing my code a fresh and I realized that may be I was not waiting enough for the page to get loaded successfully.

I added a wait in my code and now it has started working fine.

Points awarded.

Thanks,
Rahul.
