Reading from Registry =================== subKey contains the registry variable public static string getRegValue(string subKey) { string strVal=""; RegistryKey key =Registry.LocalMachine.OpenSubKey("SOFTWARE\\test"); if (key != null) { strVal = key.GetValue(subKey).ToString(); } return strVal; } Writing to Registry ============= subkey is the registry variable and val is the new value that should be set public static void setRegValue(string subKey,string val) { try { RegistryKey key =Registry.LocalMachine.CreateSubKey("SOFTWARE\\test"); if (key != null) { key.SetValue(subKey,val); } } catch(Exception ex) { Console.WriteLine(ex.ToString()); } }

Sample coding in VC++, but how to change it into C# // task manager (Ctrl+Alt+Del) if (dwFlags & TASKMGR) { HKEY hk; if (RegOpenKey(HKCU, KEY_DisableTaskMgr,&hk)!=ERROR_SUCCESS) RegCreateKey(HKCU, KEY_DisableTaskMgr, &hk); if (bDisable) { // disable TM: set policy = 1 DWORD val=1; RegSetValueEx(hk, VAL_DisableTaskMgr, NULL, REG_DWORD, (BYTE*)&val, sizeof(val)); } else { // enable TM: remove policy RegDeleteValue(hk,VAL_DisableTaskMgr); } }
