In visual basic 6, there was a module and user control in which let you post data and use certain functions of a webbrowser without having the actual webbrowser present.
It is useful for making programs that you do not want to use alot of RAM and/or hard drive.
It saves alot of time then going through the webbrowser functions and posting data that way, when you could just do something like this :
strHTML = wrapper.postwrapper("http://www.google.ca/search?hl=en&q", text1.text & "&btnG=Google+Search&meta=&aq=f&oq=")
That function would just go to google.ca, and post the data that was in textbox 1 to the search box on google.
