Registry - Check for key or value

Hello,

I am trying to check for the existance of a key or value in the registry.
I know how to write the values,

RegSetKeyValue(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Run", "StartupBuddy", REG_SZ, "0", 1);

RegSetKeyValue(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Run", "StartupBuddy", REG_SZ, "1", 1);

CreateWindow(TEXT("BUTTON"),// * GroupBox
 TEXT("Startup Settings"),
 WS_VISIBLE | WS_CHILD | BS_GROUPBOX | BS_CENTER,
 10, // Start Left
 10, // Start Top
 WidthX - 25,
 50,
 hwnd,
 (HMENU) ID_GroupBox_StartupSettings,
 NULL,
 NULL);
					
CreateWindow(TEXT("BUTTON"),// * CheckBox
 TEXT("Start with Windows"),
 WS_VISIBLE | WS_CHILD | BS_CHECKBOX,
 30, // Start Left
 25, // Start Top
 150,
 30,
 hwnd,
 (HMENU) ID_CheckBox_WindowsStartup,
 NULL,
 NULL);

But do not know how to check for them
check for value in registry, if found

CheckDlgButton(hwnd, ID_CheckBox_WindowsStartup, BST_CHECKED);

Thank you.
