Hi all,
This is my first post in here.
I am trying to create a code to get HTML data from the web (without using a web browser element), creating a local variable to store the data and being able to parse it later on using the GetElementById method.
The problem is that I am getting an error and I?m not sure how to fix it.
the code is as follows:
The error returned is : "Unable to cast COM object of type 'System.__ComObject' to interface type 'mshtml.HTMLElementCollection'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{3050F56B-98B5-11CF-BB82-00AA00BDCE0B}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."
I have looked for a solution everywhere, but no way to find something without using a web browser in the code.
This is my very first code in VB 2010 so it might contain several errors.
Could anyone help me?
thanks in advance.
