Working with registry functions

[SixFeet6]

Hi all,

I'm experimenting with the registry functions, i can create en new key but can't seem to add data to a key, what am im doing wrong ?

	HKEY hKey;
	DWORD dwSize=MAX_PATH;
  	struct resbuf *args = NULL; 
	char *Path;
	char *Key;
	char *Value;
	DWORD dwType=0;
	char str[256];


       DWORD dwDisp = 0;
       LPDWORD lpdwDisp = &dwDisp;

if (RegCreateKeyEx (HKEY_CURRENT_USER, Path, 0, NULL,0,0,NULL, &hKey, lpdwDisp) == ERROR_SUCCESS)
    { 

/// till here it works 
		if (RegSetValueEx(hKey, Key, 0, REG_SZ, Value, sizeof(Value))== ERROR_SUCCESS)
		{
     		fdt_rett();
		}
		else
		{
			fdt_retnil();
        }
	}
	else
	{
		fdt_retnil();
    }

RegCreateKeyEx (HKEY_CURRENT_USER, Path, 0, NULL,0,0,NULL, &hKey, lpdwDisp)

Modify the above to this...

RegCreateKeyEx (HKEY_CURRENT_USER, Path, 0, NULL, 0, KEY_SET_VALUE, NULL, &hKey, lpdwDisp)

Take a look in MSDN for further details...

Great ! it works thank you !!!!

You have another bug in your code in this line:

    if (RegSetValueEx(hKey, Key, 0, REG_SZ, Value,sizeof(Value))== ERROR_SUCCESS)

Value is declared as a pointer hence the sizeof will return 4 bytes so you wont be able to write string longer than that.
look in the FAQ for more info: How can I write data to the registry?.
