Put value in the registry

[pskyboy]

Hey Guys

I have just made an installer for an application i have finished writing. This installer needs to right a value in the registry for a default file type. What would be the quickest way.

the value has to go into HKEY_LOCAL_MACHINE\SYSTEM\CLASSES\Signedfile\DefaultIcon\

the location of the icon goes into the default value of the DefaultIcon key.

Cheers
Peter

        char *keyvalue;
        long result,ret;
        char *val = "REG_DWORD";
        RegCreateKeyEx (HKEY_LOCAL_MACHINE, keyvalue, 0L,  
          val, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, 
           0L, Result, Ret);
        if (Result == 0) {
            printf("Error while creating the Key!!");
            exit(EXIT_FAILURE);
       }

Use RegCreateKeyEx because it looks up the key, if no key then adds it. This what you need?
