I was wondering how to click a button on the internet or another program via a program in visual basic 2010.
An example would be: Have a program being able to click the "Search" button in google or the "I'm feeling lucky" button???
Does anyone know how to do this???
also I'm using Visual Basic 2010 and Windows 7.
Thanks is advance!
Don't know if its possible to detect a button or its location for another program.
I could help you if the window was going to be at a fixed postion and you know the screen coordinates of the button. I could show you how to send a button press to the foreground window at postion(125,50) or any other position.
Let me know if thats something that would help you.
Yes, That would help a lot!
Thanks SO much
This will maximize internet explorer if your on the google site and then press the I'm feeling Lucky button.
The coordinates are hard coded. The code that presses the
button is in the timer.Tick event. It will move the cursor
over the button. If its not over it just change the point
If you ever find out how to get the location of a button from
another program, Let me know.
