You have to improve your search skill.

While searching for "serial port" (keyword) related articles in CodeProject "MFC/C++" category, I got 49 articles.

It works in our tests. Are you sure your dialog client area is not covered by a child window?

Wild stab in the dark; the OP wants to prevent the dialog from being moved on screen.
(Why would you want to do this? it's inconsistent with other apps and will irritate users; maybe that's why Blush | :O

)

If this is the case, handle WM_NCHITTEST, and return HTBORDER instead of HTCAPTION. In addition, you will want to handle WM_SYSCOMMAND, and ignore SC_MOVE requests.

How can i : FindItem in the second column and the 3- column ...etc.?
Because my string searches only in the first column and GetItemText from second column , 3 column etc . this is my code the code from yesterday is not good for me :

void CMyList::OnOK()
{

UpdateData();
m_list2.RedrawItems(0,m_list2.GetItemCount());

CString sName = _T("Name");
m_name.GetWindowText(sName);

LVFINDINFO stInfo = {0};
stInfo.flags = LVFI_PARTIAL;
stInfo.psz = sName;
int nItem = m_list2.FindItem( &stInfo );
if( nItem != -1 )
{
// the item is in the list control
CString sSecondColumnText = m_list2.GetItemText( nItem, 1 );
// set the text to the second edit box
m_rezult.SetWindowText( sSecondColumnText );

}

}
Only this code works !
I remind you :

When you read your string then in the loop use from CString::Find for search spaces in your string and use CString::Delete for delete spaces from string

I think the better place to remove unneeded spaces is the point where you get strings from database and insert them in list control. Use the Trim member of CString to remove leading and trailing spaces. For instance:

CString text = ... // get text from FoxPro database
text.Trim();
myListControl.InsertItem(..., text);

If you need to reduce the internal spaces, then also try this:

while(text.Replace(_T("  "), _T(" ") != 0);

Maybe you should try this:

CString sName, sCity, sCountry;
m_name.GetWindowText(sName);
m_city.GetWindowText(sCity);
sCountry.Empty();

for(int nItem = 0; nItem < m_list2.GetItemCount(); ++nItem)
{
    CString const sFirstColumnText = m_list2.GetItemText( nItem, 0 );
    CString const sSecondColumnText = m_list2.GetItemText( nItem, 1 );
    if( sName == sFirstColumnText && sCity == sSecondColumnText)
    {
        sCountry = m_list2.GetItemText( nItem, 2 );
        break;
    }
}
m_result.SetWindowText(sCountry);

I hope this will give you some ideas.

There's nothing wrong with the code you've shown. This works fine:

BOOL CMyDlg::OnInitDialog()
{
    CDialog::OnInitDialog();
 
    m_list.InsertColumn(0, "Name", LVCFMT_LEFT, 100);
    m_list.InsertColumn(1, "City", LVCFMT_LEFT, 100);
    m_list.InsertColumn(2, "Country", LVCFMT_LEFT, 100);
 
    int nItem = m_list.InsertItem(0, "George");
    m_list.SetItemText(nItem, 1, "London");
    m_list.SetItemText(nItem, 2, "England");
 
    nItem = m_list.InsertItem(1, "George");
    m_list.SetItemText(nItem, 1, "New York");
    m_list.SetItemText(nItem, 2, "USA");
	 
    return TRUE;  // return TRUE  unless you set the focus to a control
}
 
void CMyDlg::OnOK() 
{
    CString     strName;
    LVFINDINFO  stInfo = {0};
 
    m_edit.GetWindowText(strName);
 
    stInfo.flags = LVFI_STRING;
    stInfo.psz   = strName;
 
    int nItem = m_list.FindItem(&stInfo);
    if (nItem != -1 )
        AfxMessageBox("Found It!");
}

You must have something else wrong.
