Hi,

I am building an application in MFC,through my application i want to add a new key and set the value to it.And again add a subkey to that key.I have written a code for it,but there might be some mistake in my code and the key is not getting created.Below is my code

C++

char *m_tmpChar;
m_tmpChar="iexplore.exe";

RegCreateKeyEx(HKEY_CURRENT_USER,L"Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer",0,NULL,REG_OPTION_NON_VOLATILE,KEY_ALL_ACCESS,NULL,&hkey,0);

RegSetValueEx(hkey,L"disallowrun",NULL,REG_SZ,(unsigned char*)m_tmpChar,strlen(m_tmpChar)+1);

 RegCloseKey(hkey);

Please kindly help me for this.

Thanks in Advance

Solution 1

It would be near by MFC :

C++

bool Test()
{
  bool bResult(false);
  CRegKey cKey;
  if (ERROR_SUCCESS ==
      cKey.Create(HKEY_CURRENT_USER,
                  _T("Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer"))) {
    bResult = (ERROR_SUCCESS ==cKey.SetStringValue(_T("disallowrun"), _T("iexplore.exe")));
  }
  return bResult;
}

Try also to use CString instead of char* :)

This code is working for other registry keys but its not working for this particular registry key , i dont know why??

Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer

Check the access rights of the Policies key. On my Win7 Pro, it is not writable for the current user. Write access requires accounts that are members of the administrator group.

As Jochen said, you could try to
- manipulate your manifest to provide the administrator rights for the application, or
- write a service started by the SYSTEM user and delegate such tasks to it
