Hi, 
 
Using C++ I need some code to find a specific value of a key. 
 
So for example, if I have ...\....\....\...\IBM 
 
Inside that folder one of the keys is called Vaild. &nbsp;I need to get the 'Data' or value back. 
 
How would you go about this?

Query Registry for Specific Value

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
