Call this member function to write the specified value into the specified section of the application's registry or .INI file.

BOOL WriteProfileInt( 
   LPCTSTR lpszSection, 
   LPCTSTR lpszEntry, 
   int nValue  


Points to a null-terminated string that specifies the section containing the entry. If the section does not exist, it is created. The name of the section is case independent; the string may be any combination of uppercase and lowercase letters.


Points to a null-terminated string that contains the entry into which the value is to be written. If the entry does not exist in the specified section, it is created.


Contains the value to be written.

Nonzero if successful; otherwise 0.

This example uses CWinApp* pApp = AfxGetApp(); to get at the CWinApp class illustrating a way that WriteProfileString, WriteProfileInt, GetProfileString, and GetProfileInt can be used from any function in an MFC application.

CWinApp* pApp = AfxGetApp();

CString strSection       = _T("My Section");
CString strStringItem    = _T("My String Item");
CString strIntItem       = _T("My Int Item");

pApp->WriteProfileString(strSection, strStringItem, _T("test"));

CString strValue;
strValue = pApp->GetProfileString(strSection, strStringItem);
ASSERT(strValue == _T("test"));

pApp->WriteProfileInt(strSection, strIntItem, 1234);

int nValue;
nValue = pApp->GetProfileInt(strSection, strIntItem, 0);
ASSERT(nValue == 1234);

For another example, see the example for CWinApp::GetProfileInt.
