What event causes column 2 to change? You need to monitor or capture that, and make the changes to column 1 at the appropriate time. Without knowing more about your code it is difficult to be more specific.

Re: changing column value to hyper link

both columns have been initialized with some values

when initial value of column 2 increases then column one value should become hyperlink.

Thanks.

Hi,

MSDN is your friend and you will be a much better software engineer if you learn to use it. The LCIDToLocaleName function[^] is available for Vista+ operating systems. The DownlevelLCIDToLocaleName function[^] is available for XP and below but unfortunately users will need to install the National Language Support (NLS) package.

You can avoid all of this by using the code I gave you here[^] which works on all operating systems >= WinXP. I've never tested it on Win2k.

Best Wishes,
-David Delaune

Howdy, you'll need the HWND of each dialog and the INT identifier of each control, or you'll need the HWND of each edit control.I'll assume the first.

C++

HWND editSrc, editDst;
char *szBuffer;
int stringLength;

editSrc = GetDlgItem(dlg1, IDC_EDITBOX1);
editDst = GetDlgItem(dlg2, IDC_EDITBOX2);

stringLength = GetWindowTextLength(editSrc);
szBuffer = new char[stringLength+1];
ZeroMemory(szBuffer, stringLength+1);
GetWindowText(editSrc, szBuffer, stringLength);

SetWindowText(editDst, szBuffer);
delete szBuffer;

Keep a public CString member variable in Child dialog class, set the member variable before calling the DoModal() or Create function of child dialog. Call SetWindowText of edit control in InitDialog.

for. eg

If CMainDlg is your Main dialog class and CChildDialog be the child.
in header of CChildDialog you declare a public member variable to hold the string

C++

class CChildDialog : public CDialog
{
 public :
 CString m_strText;
}

and in your button click function of CMainDlg do this

C++

void CMainDlg::OnClick_Button()
{
  
  CChildDialog oChildDlg; 
  oChildDlg.m_strText = strText; // This should be the edit box value
  oChildDlg.DoModal();
}

Set the variable value in CChildDialog's OnInitDialog as

C++

CChildDialog::OnInitDialog()
{
  SetDlgItemText(ID_OF_YOUR_EDIT, m_strText);
}

You can also set the text by modifying your constructor of CChildDialog, such as

C++

CChildDialog::CChildDialog(CString strText)

From class wizard, maindialog's member variables I added a member variable to the editbox which gets the editbox's value and then as you said, I equalize each variables but than it returns nothing from main dialog ??? Frown | :(

You could use GetDlgItemText()[^] and its counterpart SetDlgItemText().

I did it as Mahdu replied and by your hint... like

C++

void mainform::OnBnClickedButton2()
{
			GetDlgItemText(IDC_EDIT1,newform.strtext);
}

BOOL newform::OnInitDialog()
{
			SetDlgItemText(IDC_EDIT1, strtext);
}

How about something like:

CMainDlg::OnButtonClick()
{
    CString strText;
    m_edit.GetWindowText(strText);
 
    CSecondDlg dlg;
    dlg.setData(strText);
 
    dlg.DoModal();
}
 
CSecondDlg::setData( LPCTSTR lpszText )
{
    m_strText = lpszText;
}
 
CSecondDlg:OnInitDialog()
{
    m_edit.SetWindowText(m_strText);
}

I'm a big fan of weak coupling, so tying these two dialogs together like this would not be my first choice. I would opt for a "data transfer" or "liaison" class instead. This is a one-instance class where you would put all of your shared data.

By the way, you can just explain this :

CFileDialog *pOpenDlg=new CFileDialog(FALSE,".txt",NULL,OFN_OVERWRITEPROMPT,"Text Files (*.txt)|*.txt|All Files(*.*)|*.*||");

The current list should be in file WinNT.h; search for keyword LANG_NEUTRAL. See also second response.

Further research suggests you should use one of the locale support functions such as EnumSystemLocalesEx()[^].
