Question : C++ Exporting Registry Branch

Good-day;

I am having some troubles exporting a registry branch in C++. The code below will export a branch, however it is in an unusable format, it looks to be a binary file...

What I am trying to accomplish is the end result of the saved registry file to be in the same format as if I selected "File -> Export" in the Registry Editor.

Thank you for your help and time;
Kind regards

Sorry, have been away from my email for a while....

Yes, you can use RegSaveKeyEx and RegLoadKey. That IS what they are intended for, it is just that the result of RegSaveKeyEx is not in the format that you were after in your question as it was originally stated.
