santhosh padamatinti

Hi to all, I am using windows registry. please look the following.

const char* subkey ="Software\\Microsoft\\Windows NT\\CurrentVersion";

  if(RegOpenKey(HKEY\_LOCAL\_MACHINE,subkey,&hKey)== ERROR\_SUCCESS)
  {
	  cout<<"register is opened";
  }
  else
  {
	  cout<<"still not working";
  }

Above one is working correctly. And also displaying the message correctly. But when subkey i written like follows it is not working.

const char* subkey ="Software\\Microsoft\\Windows NT\\CurrentVersion\\Windows Messaging Subsystem";

I am not getting the exact problem please address the solution.... Thanks in advance.....

Sorry friends , I got the solution. I am reading incorrectly. I am reading in local machine instead of reading current user. Any way it is working thanks......

You can use ATL class CRegKey to do registry operations

Per MSDN: If RegOpenKey() fails, the return value is a nonzero error code defined in Winerror.h. You can use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to get a generic description of the error.
