Stop Flicker during the loading

[Huskey]

Hi,

I got a problem. When I tried to read a database which contains a huge list of columns, the CListBox flickers during loading. How can I eliminate this effect?

for (int h = 0; h < columnnames.size(); h++)
{
if ((colNames == &quot;Integer&quot || (colNames ==&quot;String&quot)
{ myColumns.Format(_T(&quot;%s\t%s&quot, columnnames[h].GetBuffer(), colNames.GetBuffer()); }

m_ctrlCheckListBox.AddString( myColumns );
m_ctrlCheckListBox.SetCurSel(0);
m_ctrlCheckListBox.SetCheck(h,1);
}

thanks!

Try so:
for (int h = 0; h < columnnames.size(); h++)
{
if ((colNames == &quot;Integer&quot || (colNames ==&quot;String&quot)
{ myColumns.Format(_T(&quot;%s\t%s&quot, columnnames[h].GetBuffer(), colNames.GetBuffer()); }

m_ctrlCheckListBox.AddString( myColumns );
}
m_ctrlCheckListBox.SetCurSel(0);
m_ctrlCheckListBox.SetCheck(h,1);
