Data Between 2 dialogs

I have the main dialog with a find button. When pressed it opens a dialog (using DoModal()) with a list control that lists all records. I have an option to select edit. When this is done i want to move all the data back to the main screen. here is what i have done. Declared an instance of the class of the dialog i want to send it to with that instance i have set all the meber variables called CDialog::OnOk() and then called UpdataData(FALSE) but when it is done all the fields are still blank. Any help please?

Write code in the main dialog that gets data from the second dialog after DoModal of the second dialog returns.

Hi,

In OnOK of your second dialog call UpdateData(TRUE) instead of UpdateData(FALSE)

Then in the main you will have the correct data of your second dialog.

CMyDialog::OnOK(){
UpdateData(TRUE);
CDialog::OnOK();
}

I would even say that the call of UpdateData(TRUE) is automatically done in the CDialog::OnOK() function

Thanks a lot for the replies. It is working great.

Here's a sample that modifies a list item on a double click. It creates a list of items in an std::vector and puts the items in a virtual list control. When a user double clicks on the item, the underlying item object is passed to the dialog.

Here's the code that displays the edit dialog on double click

Code:

---


void CListItem2DialogDlg::OnNMDblclkListctrl(NMHDR *pNMHDR,
LRESULT *pResult)
{
int nItem = 0;
CPoint pt;
GetCursorPos(&pt);
 
m_ctlList.ScreenToClient(&pt);
 
if( INVALID_INDEX != (nItem = m_ctlList.HitTest( pt ) ) )
{
// Retrieve the CLVItemData object associated with this item
        CLVItemData* pLVItemData
        = reinterpret_cast<CLVItemData*>(m_ctlList.GetItemData( nItem ) );
 
        if( NULL != pLVItemData )
        {
        CLVItemEditDlg dlg( pLVItemData, this );
        if( IDOK == dlg.DoModal() )
        {
                // Refresh this item
                m_ctlList.RedrawItems( nItem, nItem );
        }
        }
}
*pResult = 0;
}

The edit dialog code gets a pointer to the selected item. DoDialogExchange
acts on the pLVItemdata directly (which simplifies the dialog code).

Code:

---

CLVItemEditDlg::CLVItemEditDlg(CLVItemData* pLVItemData, CWnd* pParent /*=NULL*/)
: CDialog(CLVItemEditDlg::IDD, pParent)
, m_pLVItemData( pLVItemData )
{
ASSERT( NULL != m_pLVItemData );
}
void CLVItemEditDlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Text(pDX, IDC_COLUMN1, m_pLVItemData->GetColumnOne());
DDX_Text(pDX, IDC_COLUMN2, m_pLVItemData->GetColumnTwo());
DDX_Text(pDX, IDC_COLUMN3, m_pLVItemData->GetColumnThree());
}
