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

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);

I hope this helps and your problem will be finally solved.

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.

Of course! You've not ever specified that you wanted to search subitems, which FindItem() does not do.

This has already been shown to you. What part did you not understand?

Hi,

I am saving recorded file in a folder, but am hardcoding the name in the code itself.I want the recorded .wav file to get the name as current date and time for e.g. 08/09/0611:55:39.wav.I get the name of the file in a string variable but it does not gets saved coz it does not recognise the slash(/).I want a way in which i can convert the slash(/) in the date string to hyphen(-).
For e.g 08/09/0611:55:39.wav has to be converted to 08-09-0611:55:39.wav.
I am using VC++, please suggest me how can i solve this problem.
Thanks

Hello everyone,

I found the log file size is becoming larger and larger. Any ideas to reduce the file size or make log file size managed, for example, keep the log file be fixed size or some other policies? Any reference tutorials or open source samples to recommend?

thanks in advance,
George
