Registry Programming Problem/DevC++

Here is my program. The errors it is giving me are:

line 27: passing `HKEY__ **' as argument 1 of `RegDeleteValueA(HKEY__ *, const CHAR *)'

line 29: passing `HKEY__ **' as argument 1 of `RegCloseKey(HKEY__ *)'

However, on MSDN, it tells me that the PHKEY can be passed to RegCloseKey.

Code:

---

#include <windows.h>
#include <iostream.h>

int main()
{ char csubkey[70],clpvaluename[70];
  PHKEY phkResult;
  long gooddelete;
  int loop;
  cout<<"Do you want to delete a registry value?"<<endl
          <<"1 to delete, 0 to quit"<<endl;
  cin>>loop;

  while(loop)
  {
      cout<<endl<<endl<<"Name of subkey to delete:"<<endl;
      cin>>csubkey;
      cout<<"Name of value to delete:"<<endl;
      cin>>clpvaluename;


      RegOpenKeyEx(HKEY_CURRENT_USER,
                              csubkey,
                              0,0,
                              phkResult);

      gooddelete=RegDeleteValue(phkResult,clpvaluename);

      RegCloseKey(phkResult);

      cout<<endl<<endl<<endl;
   
      if (!gooddelete)
        {cout<<"Delete successful";}
        else
      {cout<<"Delete unsuccessful";}
 
      cout<<"Do you want to continue?"<<endl<<"1 to continue, 0 to quit";
      cin>>loop;
  }
 return 0;
}

sorry about the bad indentation, it didn't paste over too well.

This compiles....but I havent tested it....or even worked out what you are trying to do :)

Code:

---

#include <windows.h>
#include <iostream.h>

int main()
{ char csubkey[70],clpvaluename[70];
  HKEY phkResult;
  long gooddelete;
  int loop;
  cout<<"Do you want to delete a registry value?"<<endl
          <<"1 to delete, 0 to quit"<<endl;
  cin>>loop;

  while(loop)
  {
      cout<<endl<<endl<<"Name of subkey to delete:"<<endl;
      cin>>csubkey;
      cout<<"Name of value to delete:"<<endl;
      cin>>clpvaluename;


      RegOpenKeyEx(HKEY_CURRENT_USER,
                              csubkey,
                              0,0,
                              &phkResult);

      gooddelete=RegDeleteValue(phkResult,clpvaluename);


      RegCloseKey(phkResult);

      cout<<endl<<endl<<endl;
   
      if (!gooddelete)
        {cout<<"Delete successful";}
        else
      {cout<<"Delete unsuccessful";}
 
      cout<<"Do you want to continue?"<<endl<<"1 to continue, 0 to quit";
      cin>>loop;
  }
 return 0;
}

I have :

LONG RegOpenKeyEx(
HKEY hKey, // handle of open key
LPCTSTR lpSubKey,// address of name of subkey to open
DWORD ulOptions,// reserved
REGSAM samDesired,// security access mask
PHKEY phkResult // address of handle of open key
);

and ( not like you)

LONG RegCloseKey(
HKEY hKey // handle of key to close
);

so you could try :


HKEY hKey

......

RegOpenKeyEx(HKEY_CURRENT_USER,
csubkey,
0,0,
&hKey);


( and maybe RegCloseKey(hKey); )


Since phkResult is a pointer to a HKEY (that you have noy declared), &phkResult is its address so a pointer to a pointer ...

Thanks Gert.:D

The two stars should have been a big tip : )
