Hi,
My program is getting stuck in an infinite loop in the class ExtComboBox::::OnFilterPopupListSyncSelection when there is only one item in the list
It is getting stuck in the loop:
// select new item
INT nIndex = 0;
while( (nIndex = FindStringExact( nIndex, sItemText) ) != CB_ERR )
{
if( GetItemData( nIndex ) == dwItemData )
{
CEdit * pEdit = GetInnerEditCtrl();
ASSERT( pEdit != NULL );
ASSERT_VALID( pEdit );
if( pEdit != NULL )
pEdit->SetRedraw( FALSE );
SetCurSel( nIndex );
// make text non-selected
if( !bSetEditSel )
SetEditSel( -1, -1 );
if( pEdit != NULL )
{
pEdit->SetRedraw( TRUE );
pEdit->Invalidate();
pEdit->UpdateWindow();
}
break;
}
}
as GetItemData( nIndex ) == dwItemData is not true and nIndex=0 as there is only one item
Regards,
Eddie

I don’t know if this is the correct way to fix the problem but I updated the method with the following and rebuilt the library
// select new item
INT nIndex = 0;
INT nRepCount=0;
while( (nIndex = FindStringExact( nIndex, sItemText) ) != CB_ERR )
{
if( GetItemData( nIndex ) == dwItemData || (nRepCount>0 && nIndex==0))
{
CEdit * pEdit = GetInnerEditCtrl();
ASSERT( pEdit != NULL );
ASSERT_VALID( pEdit );
if( pEdit != NULL )
pEdit->SetRedraw( FALSE );
SetCurSel( nIndex );
// make text non-selected
if( !bSetEditSel )
SetEditSel( -1, -1 );
if( pEdit != NULL )
{
pEdit->SetRedraw( TRUE );
pEdit->Invalidate();
pEdit->UpdateWindow();
}
break;
}
nRepCount++;
}

We failed to reproduce the infinite loop. How do you initialize the combo box? Would you send us the code or a test project?
