Collecting Data in a web frame using Labview

Collecting Data in a web frame using Labview

‎06-22-2010 02:47 AM

Hi everybody, I was wondering if it's possible to collect data from a web frame using it's source code.

I have included my web frame and an extract of its source code. I hope you can help me to find the way to resolve it.

 

I'm available for any kind of questions 😄

 

Thanks

Hello,

 

You have to know how the web page is built, in order to retrieve the requiered data. Here is an example of how you can process. Use a WebBrowser ActiveX control on your front panel, and then use the properties and method exposed by this control. The loop waits for page loading completion. You may have to convert variant data (such as the value of Document) in the ActiveX reference class you need to manipulate.

 

Here in this sample, I just read the content of the <body>'s web page.
