Re: serial reader ui-thread solution?

Yes I fixed the problem... forgot to open the com port with the
overlapped flag :-(
According to this problem: I`ll try to install the reader-thread as
workerthread and this workerthread will send all pkts to the visible
window (I`ve installed for the document-class) and the document class
have a member variable of the comport class (doing the reader-thread
initialization and so on) which will tell these data pkts where they
have to go (to threadA or threadB by a PostThreadMessage()). With this
solution the reader-thread can work as long as no error or shutdown
event occurred.

Until this loop terminates, your message pump is dead. You cannot rece=
ive or process any
messages coming into the UI thread. There are very complex ways to add=
ress this problem,
but the simplest one is to move this to a worker thread and let it (as yo=
u have shown
above) PostThreadMessage to your UI thread. So this loop itself cannot=
be in the UI
thread, but if you want a UI thread to act as some kind of multiplexor/de=
multiplexor,
that's your call

The express editions cannot use MFC?
Yes. I believe the MFC components only come with the paid versions.
Does that mean I will not be
able to get my Visual C++ NET 2003 macro recorder project to work
with the express edition?
From what you mentioned about your project, I don't think you'd gain
much benefit from moving it to a newer toolset. If you had plans to
make use of newer C++ standards facilities, then such a move may be
worthwhile, but if you're happy with what you have, why change?

I need to create a tile view using CListCtrl with checkbox for each
item. I got two issues:
1) The checkboxes are not reponsive (if I don't use tile view,
everything is fine);
2) The whole item got selected / focus when I check the checkbox (I
want it work just like the regular checkboxes --- the item itself not
highlighted / focused).
The following is my source code:
DWORD exStyle = m_listCtrl.GetExtendedStyle();
m_ listCtrl.SetExtendedStyle(exStyle | LVS_EX_CHECKBOXES |
LVS_EX_LABELTIP);
// Title info
LVTILEVIEWINFO tvi = {0};
tvi.cbSize = sizeof(tvi);
tvi.dwMask = LVTVIM_COLUMNS;
tvi.cLines = 0;
m_ listCtrl.SetTileViewInfo(&tvi);
m_ listCtrl.DeleteAllItems();
int item = 0;
// Inset list items
String capName;
bool bEnabled = false;
int count = 0;
HashPosition pos = m_capsHash.GetStartPosition();
while (!pos.IsNil())
{
m_capsHash.GetNextAssoc(pos, capName, bEnabled);
count = m_ listCtrl.GetItemCount();
item = m_ listCtrl.InsertItem(count, capName);
ListView_SetCheckState(m_ listCtrl.m_hWnd, item, bEnabled);
}
m_ listCtrl.SetView(LV_VIEW_TILE);
Any idea? Thanks in advance=85
