CWinApp::WriteProfileInt

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 
);

Parameters

  • lpszSection
    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.

  • lpszEntry
    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.

  • nValue
    Contains the value to be written.

Return Value

Nonzero if successful; otherwise 0.

Example

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.
