CString to const unsigned *char 1

[Malcav]

Hi
Sorry if this has been answered before but I can find it.
I am creating a registry thing to store database connection information. I get a CString for the value. I can change the CString into a const *char but apparently it needs const unsigned *char

thought it might be helpfull if you saw my code :

void CreateReg (CString ConnStr)
{
const char *String ;
long result;
unsigned long result2;
unsigned long * presult2 = &result2;
HKEY keyvalue;
HKEY * pkeyval = &keyvalue;
char * subkey;

subkey = new char[15];
strcpy(subkey, "Software\\PROGRESSOR");

result = RegCreateKeyEx(HKEY_LOCAL_MACHINE, subkey, 0, "REG_DWORD",
REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, NULL, pkeyval, presult2);

if (result == ERROR_SUCCESS)
{
RegSetValueEx(keyvalue, "ConnStr", 0, REG_DWORD, String , 8);
}
}

(it is stolen from a previous registry post on here)

There are quite a few more than 15 characters in your string.
I don't see why you need to copy the string in the first place.

There is no need to create separate variables for this.

result = RegCreateKeyEx(HKEY_LOCAL_MACHINE, "Software\\PROGRESSOR", 0, "REG_DWORD",    
                        REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, NULL, &keyval, &result2);

You don't set this to point to anything before you use it.

I imagine the CString has a method of getting at the raw data, then you can have

]
unsigned char raw[8];
memcpy( raw, connStr.something(), 8 );
RegSetValueEx(keyvalue, "ConnStr", 0, REG_DWORD, raw, 8);

as I said I ripped the code from another post about registries. the 15 was there from before.

Thanks for the help will give it a go.
