Reading registry

Hey guys, I was searching alot in google but I could not find a way that worked to read the data of a key. I used this to open the key

Code:

---

RegOpenKeyEx(HKEY_LOCAL_MACHINE , "Software\\Someapp\\Theapp" , 0 ,
                KEY_READ , &location );

  RegQueryValueEx(hkey , "Path"  , NULL , &data_type ,
                  (BYTE*)&value , &size);

---

But how can I read the data inside? Lets say that "Path" is the directory of the application.

Shouldn't location be instead of hkey, and I think you got more than 2 erros there... read at msdn or google for more examples.

Okay well I redid the code and now its working.

Code:

---

int main ()
{
    HKEY keyHandle;
    char rgValue [1024];
    char fnlRes [1024];
    DWORD size1;
    DWORD Type;

        if( RegOpenKeyEx(    HKEY_LOCAL_MACHINE,
            "SOFTWARE\\somesoft\\app",0,
            KEY_QUERY_VALUE, &keyHandle) == ERROR_SUCCESS)
            {
                size1=1023;
                RegQueryValueEx( keyHandle, "Path", NULL, &Type,
                    (LPBYTE)rgValue,&size1);
                printf( "Your path is %s\n", rgValue );
            }   
        else strcpy(fnlRes,"Somesoft is not installed on your computer!");
   
            RegCloseKey(keyHandle);
                        std::cin.get();

return 0;
}

But now I want to go to that directory I tryed using

Code:

---

system ("cd %s"):

---

And as I expected it didn't work any help?

EDIT: fixed every thing works
