The Solution Rating System
|
||
With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.
Your Input Matters If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support. Thank you! |

Hi tsp2002,
ok, to derive your own class it's simply enough to do something like this:
Create two new files:
1. MyMultiColumnComboBox.h
> #pragma once
>
> class CMyMultiColumnComboBox : public CMultiColumnComboBox
> {
> public:
> virtual void SelectCurrentItem();
> };
2. MyMultiColumnComboBox.cpp
> #include "stdafx.h"
> #include "MultiColumnComboBox.h"
>
> void CMyMultiColumnComboBox::SelectCurrentItem()
> {
> int nIndex = GetCurrentItem();
>
> CString strText;
> CListCtrl* pList = GetListCtrl();
>
> if ( NULL != pList && nIndex >= 0 )
> {
> strText.Format( "%s, %s, %s", pList->GetItemText( nIndex, 0 ), pList->GetItemText( nIndex, 1 ), pList->GetItemText( nIndex, 2 ) );
> }
>
> GetEdit()->SetWindowText( strText );
>
> // this is copied from original source
> if (nIndex >= 0)
> if (CWnd* pParent = GetParent())
> pParent->SendMessage(m_nSelChange, (WPARAM)GetDlgCtrlID(), (LPARAM)m_hWnd);
> }
Then where you now use CMultiColumnComboBox replace
> #include "MultiColumnComboBox.h"
with
> #include "MultiColumnComboBox.h"
and
> CMultiColumnComboBox m_wndCombo; // or whatever name you use
with
> CMyMultiColumnComboBox m_wndCombo;
This should do the job ...
Hope that helps,
ZOPPO
