使用RegSetValueEx函数

插入字符串(REG_SE):

TCHAR szTest[32];

wcsncpy(szTest, TEXT("test.dll"), 32);

int iLen = wcslen(szTest);

RegSetValueEx(hKey, TEXT("test"), 0, REG_SZ, (LPBYTE)szTest, sizeof(TCHAR)*iLen );  

插入整数(REG_DWORD):

DWORD dwValue = 1234; 
long setRes = RegSetValueEx (hKey, L"test", 0, REG_DWORD,(CONST BYTE*)&dwValue,sizeof(DWORD));
