Read a Registry Key Value and react to it

Recommended Posts

Hi,I'm new to XML and am only just beginning to understand the scope of it, basically I'm looking to read a registry key value from the pc and write it to the screen, and then dependent on the value I would like to download and run a program file from a file server if the value of this key is less than the value of the program's product version.Is this possible, within XML and if possible could someone provide me with some insight?Thanks in advance

No, XML can't actually do anything. It's not a programming language, it's just a format to store data. It's about as active as a plain text file.If you want to make the computer do something you'll have to learn C++, Java or some other programming language.
