Predictably, the Windows CE Registry is a leaner version of its desktop cousin. This means that you may want to re-evaluate the kind and amount of data your application stores in the Registry. There are two basic groups of functions for accessing Registry data on a CE device: The ones that access data in place, and the ones that access the Registry of the device from the desktop.
For example, the CE side function for accessing a Registry key looks like this:. To perform the same operation on a connected device from an application executing on the desktop, you would use this function instead of the one shown above:. Some people avoid using the Registry at all, being intimidated by the implications of a misstep. Certainly, corrupting the Registry could create serious problems. However, when all is said and done, the CE Registry is simply a database. Like any database, we need to treat the Registry in a way that ensures its consistency, keeps it as compact as possible, and accesses it in the most efficient fashion.
I make this point because on the desktop, the Registry has become more like a five-family garage sale with every passing year. On CE, its important to be organized and thrifty when deciding what data an application registers. Use the Registry sparingly and efficiently. Under CE, significant size and performance penalties occur when accessing deeply nested keys.
For this reason, try to make Registry trees as flat as possible. Also, because Registry access in general is a fairly expensive operation, another way of optimizing Registry data storage is to aggregate individual named key values into a single element. By using this strategy, your application makes one call to retrieve Registry information and parses data items from the aggregate.
This approach has the dual advantages of reducing both the number of key accesses and the storage space used by the values. Porting Tip: Redesigning the structure of your Registry tree may give your application a big performance boost. As you use the example menu choices, try inspecting the registry of the device to observe the changes in keys and values.
As in previous examples, we include only the main source file RegDemo. You can generate the rest of the source using development environment wizards, and then paste the functional elements of the example into your generated code skeleton. This approach protects you from path name conflicts that might occur if you used my support code files. The parameters to RegCreateKey, in the order shown, are the handle to the parent key; the name, as aUnicode string, of the key to add; a NULL placeholder for a reserved parameter; the class name of the key as aUnicode string; three more place holders set to 0,0, and NULL respectively; the address of a variable to receive the returned handle if the key is created successfully; and the address of a Variable to receive the disposition of the call.
There are four reserved key handles you may use to access the top level of the CE Registry. Finally, make note of the dwDisp parameter.
Use this value to detect whether or not the key existed before the call. Skipping over the message box code, we finish the handling of this case by closing the key handle. This is a very important step because leaving the key open may cause subsequent accesses to fail.

Combine multiple named values into a single named value element that is parsed by the application, so you can retrieve startup information in a single key access.
