calling Parametrised construtor with less number of arguments

[saxenavaibhav17]

Actually at some place I am creating object of outcome class.

its taking five argument.

i don't want to give 3 and 4 th argument.

i want to give 1,2 and 5 th argument.

Outcome ot(0,MW_MESSAGE, , ,this);\



previously it was written like this

Outcome ot(0,MW_MESSAGE);

working fine



now situation come i need to give it a handle of parent window so i
need to pass this there.



base condtion is that I don't want to change the architure of
Constructor.

it should be as like as it was.











Outcome:utcome( int retVal, SeverityIndex sevIndex, UINT
uTitleStrID,DWORD dwHelpID, CWnd* pParentWnd/* = NULL*/)
{
m_retVal = retVal;
m_SevIndex = sevIndex;

m_uTitleStrID = uTitleStrID;

// test if it is a valid string id
if( m_uTitleStrID )
{
//MWResourceLoader resLoad;
CString strTitle;
BOOL bValid = strTitle.LoadString(m_uTitleStrID);
ASSERT(bValid);
}

// Set the Help ID
m_dwHelpID = dwHelpID;
m_bChangeMessageBoxButtonLabels = FALSE;
m_pParentWnd = pParentWnd;
}

You can either reorder the arguments in the constructor so that the
currently 5th parameter becomes the third, or you can can make a new
constructor taking only the three parameters you are interested in.

Outcome:Outcome( int retVal, SeverityIndex sevIndex, UINT
uTitleStrID,DWORD dwHelpID, CWnd* pParentWnd/* = NULL*/)

By the way, this is not the real constructor is it, because this one
can't be called with just two arguments.

As I said, you can always create a new constructor.
