Changing the title of the MessageBox for DDX_Text() - c++

Question

The message box which is displayed when validation has the title same as that of the project.
I searched MSDN and in google for changing the title of the message box for DDX_Text().
Below is the code snippet form
void CPower_Module::DoDataExchange(CDataExchange* pDX)
{
CDialogEx::DoDataExchange(pDX);
DDX_Text(pDX, IDC_POWER_TXT_IGNITION_OFF_DELAY, delayOffWhenIgnitionIsOff);
}
When the user tries to delete the data in the text box, he will be shown a message Box as
with the application name as the title.
How do I change the title of the message box keeping the functionality same?

Internally AfxMessageBox is called. This function always uses the application title as a title for the message box. The value is stored in CWinApp::m_pszAppname. It is just a LPCTSTR.
Just create a class like this.
class CChangeAppTitle
{
public:
CChangeAppTitle(LPCTSTR pszNewTitle)
: m_strTitle(pszNewTitle)
, m_pszOldTitle(AfxGetApp()->m_pszAppTitle)
{
AfxGetApp()->m_pszAppTitle = m_strTitle;
}
~CChangeAppTitle()
{
AfxGetApp()->m_pszAppTitle = m_pszOldTitle;
}
private:
CString m_strTitle;
LPCTSTR m_pszOldTitle;
};
In DoDataExchange or before you call UpdateData just activate the class:
{
CChangeAppTitle appTitle(_T("my app title");
UpdateData();
...
Be aware that all message boxes that my be initiated by a timer, while this dialog is open, will show the new app title. Also a COM automation that is activated during this class is active will also return the changed app title.

Just Set Your Caption in MessageBox Parameter.
CString v1_sMessageToDisplay;
v1_sMessageToDisplay.Format(_T("Saved Successfully to C:/IniGui/"));
MessageBox(v1_sMessageToDisplay, _T("Your Caption"), MB_ICONINFORMATION);
