1. This sample provides you with code (in the CEOwnerInfo.h file) to get and set Owner information
2. The included file also will get and set the Notes information

The Code:

// Owner information is found in the HKEY_CURRENT_USER\\Control Panel\\Owner

// Keys Owner and Notes

// Owner info is fixedlength Unicode in a large binary datatype

 

It is important to note that these are the fixed field lengths in the Owner Info control panel. Therefore the actual values you would use if setting up an array of TCHAR's is the named value plus 1 for the NULL character.

// Name: 32 TCHAR

// Company: 32 TCHAR

// Address: 128 TCHAR

// Work Phone: 24 TCHAR

// Home Phone: 24 TCHAR

// These lengths include space for the NULL

#define OWNERNAMELENGTH 33 //TCHAR + NULL

#define COMPANYLENGTH 33

#define ADDRESSLENGTH 129

#define WORKPHONELENGTH 25

#define HOMEPHONELENGTH 25

 

So this is the definition of the struct which is used by the Owner Info functions.

typedef struct {

UINT cbSize;

TCHAR OwnerName[OWNERNAMELENGTH]; //32 + NULL

TCHAR Company[COMPANYLENGTH]; //32 + NULL

TCHAR Address[ADDRESSLENGTH]; //128 + NULL

WORD Reserved1[16]; //16

TCHAR WorkPhone[WORKPHONELENGTH]; //24 + NULL

WORD Reserved2[16]; //16

TCHAR HomePhone[HOMEPHONELENGTH]; //24 + NULL

WORD Reserved3; // 2

} CEOWNERINFO, *LPCEOWNERINFO;

 

And this is the definition of the struct which is used by the Notes Info functions.

// These lengths include space for the NULL

#define NOTELENGTH 120 //TCHAR + NULL

typedef struct {

UINT cbSize;

TCHAR Note[NOTELENGTH]; //119 + NULL

WORD Reserved1[74]; //16

} CEOWNERNOTEINFO, *LPCEOWNERNOTEINFO;

 

These are the functions defined in this include file.

BOOL GetCEOwnerInfo(CEOWNERINFO* poinfo);

BOOL SetCEOwnerInfo(CEOWNERINFO* poinfo);

//

BOOL GetCEOwnerNoteInfo(CEOWNERNOTEINFO* poninfo);

BOOL SetCEOwnerNoteInfo(CEOWNERNOTEINFO* poninfo);

//

BOOL GetCEOwnerInfo(CEOWNERINFO* poinfo){

This is the key which contains the Owner and Notes Info. Key/Value pairs.

retCode = RegOpenKeyEx (HKEY_CURRENT_USER,

TEXT("ControlPanel\\Owner"),

0,

KEY_READ,

&hKey);

 

This is the key which contains the Owner Info.

retCode = RegQueryValueEx( hKey, // handle of key to query

TEXT("Owner"),

NULL,

&dwType,

(LPBYTE)poinfo->OwnerName,

&cbData);

This is the setting the Owner Information after insuring that the last byte in the strings is set to NULL.

BOOL SetCEOwnerInfo(CEOWNERINFO* poinfo){

…

// Set "Owner" data

poinfo->OwnerName[OWNERNAMELENGTH - 1] = '\0'; //Insure it is NULL terminated

poinfo->Company[COMPANYLENGTH - 1] = '\0'; //Insure it is NULL terminated

poinfo->Address[ADDRESSLENGTH - 1] = '\0'; //Insure it is NULL terminated

poinfo->WorkPhone[WORKPHONELENGTH - 1] = '\0'; //Insure it is NULL terminated

poinfo->HomePhone[HOMEPHONELENGTH - 1] = '\0'; //Insure it is NULL terminated

retCode = RegSetValueEx(

hKey, // handle of key to set value for

TEXT("Owner"),

NULL, // reserved

dwType,

(LPBYTE)poinfo->OwnerName,

cbData);
