registry and permission

[donquixote]

I notice there are many postings concerning this. Still I didn't get my problem solved.

Two basic questions: (1) what exactly is the required permission for a program to write to registry, say, something under HKEY_CURRENT_USER?
(2) Is it possible that I have permission to manually change a key while don't have permission do it with a program?

The problem I had is that my calling to RegQueryValueEx alway get ERROR_ACCESS_DENIED. I can change the key with regedit without problem. When I check the permission with REGEDT32, my account has full control of that key. It is under HKEY_CURRENT_USER.

Any comments are appreciated.

to use RegQueryValueEx The key must have been opened with the KEY_QUERY_VALUE access right

HKEY OpenKey;

RegOpenKeyEx(HKEY_CURRENT_USER,"Software\\MySs0fFTWare\\Settings",NULL,KEY_QUERY_VALUE,&OpenKey)

to write i use
RegOpenKeyEx()
RegCreateKey()
RegSetValueEx()

Thank you very much. You got the exact problem! I just figured out after various wrong paths. Wish my mistake helps others who saw this.
