I wrote a MFC ActiveX control and i want to define some mnemonic keys for it, but my OnGetControlInfo implementation doesn't get called by the Test Container.
Do you know why?

hi,
I want to make an program that reads the content of a listbox from a different source. The reason is, if there are a 1000 records requested over a network it only has to load the records that are shown. Causing that the user doesn't have to wait for the downloading of all the 1000 records.
the way i'm doing it now is by filling the listbox with empty records:
<br />
for (int i = 0; (!(i > Db.GetCount())); i++)<br />
{<br />
m_MyListBox.InsertString(i, "");<br />
}<br />
Then, Wenn the user wants to see a different part of the listbox i update the data:
<br />
int cur, max;<br />
<br />
cur = m_MyListBox.GetScrollPos(SB_VERT);<br />
max = Db.GetCount();<br />
<br />
if (!(cur + 5 > max))<br />
{<br />
max = cur + 5;<br />
}<br />
<br />
for (int i = cur; (!(i > max)); i++)<br />
{<br />
m_MyListBox.DeleteString(i);<br />
m_MyListBox.InsertString(i, Db.GetItem(i));<br />
}<br />
Now, I want to run this function wenn the Scrollbar is moved, but i dont know witch message to catch. Anyone have the solution?
I hope my explaining of the problem is correct, my english isn't that great...

Consider LVN_BEGINSCROLL and LVN_ENDSCROLL.

Hi,
I have set up a global windows hook for WH_GETMESSAGE and it works. I receive messages for each thread. But I dont seem to be getting WM_NOTIFY message for some reason.
I then tried using WH_CALLWNDPROC which works. I see WM_NOTIFY messages. The problem with CALLWNDPROC is that you cannot change the messages but WH_GETMESSAGE can.
Does anybody know a way I can make WH_GETMESSAGE see WM_NOTIFY messages.
Thanks

Hi there,
this is not such a very concrete question, but anyway:
How do you make software with different language support??
I mean, when you have to make your output present in different languages like french, english, german... (not chinese or sth.)
I'm currently using different resources and stringtables, but it's like, um, circuitous, err, like a lot of work, especially when you have to do it afterwards... 
So, how do you do it ?
Thanx!
Olli!

If you look under the books in the Visual C++ MSDN Library you will find "Developing International Software for Windows 95 and WinNT" and you may be happy to know that Microsoft press had planed releas a newer edition of this book some time this year.
Thanks for reminding me I am off to see if it has been released yet, so I can order it.
Trust in the code Luke. Yea right!

dear all,
i've written a small piece of code ( a hidden window) which detects windows shutdown and then logs the timestamp in a file. i'm using the following code in the message loop-
while(GetMessage(&Msg, hwnd, 0, 0) > 0)
{
if (flg_shutdown == 1)
{
flg_shutdown = 0;
Run(); //logs time stamp in a file
ShutDown(); // shutsdown the system using ExitWindowsEx(...)
}
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
now my wm_queryendsession handler is as follows
case WM_QUERYENDSESSION:
{
if (lParam & ENDSESSION_LOGOFF)
flg_type = 1; //logoff
else
flg_type = 2; //shut down
flg_shutdown = 1;
return false; // don't shutdown now. shutdown after Run() is executed
}
break;
the problem is that when i logoff/shutdown nothing happens until i do something with the window (move cursor over it or click on it or resize it).
when i do so, everything works fine.
what could be the problem. i even tried the following message loop
while(GetMessage(&Msg, hwnd, 0, 0) > 0)
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
if (flg_shutdown == 1)
{
flg_shutdown = 0;
Run(); //logs time stamp in a file
ShutDown(); // shutsdown the system using ExitWindowsEx(...)
}
}
but same problem.
can someone help me out.
Thanx and Regards

WM_QUERYENDSESSION is sent which means that it is not seen by the message loop. The code in the message loop will be executed the next time a message is posted to your window.
Maybe you should move your code to the message handler.

thanx for ur concern.
i am executing the code when wm_queryendsession returns 0 (i.e. logoff or shutdown is aborted)
if i try to run the code (starting an application for file write operation) in the messagehandler itself, i cannot execute the application because windows is shutting down.
i also tried to send a message(wm_lbuttonup) in the loop, but still i can't make it work

The problem is that the message loop does not get called when a message is sent to your handler. If you cannot perform your task in the message handler you have to make sure that the message loop is triggered without any user interaction.
Maybe you coud post a message to your window, e.g.
PostMessage(hYourWindow, WM_NULL, NULL, NULL);
This will trigger the message loop some time after your handler has finished.

I have a MFC (server) application that works with sockets.
It should do the following:
1. Waits for an incomming client connection request (only 1).
2. Accept that connection request.
3. Send something to the client.
4. Receive something from the client.
5. Close the accepted connection.
6. ... go to 1. (wait for incomming client connection request)
Only 1 client can send something to the server.
So, I tried to imeplement it like this:
WSAStartup(...);
server = socket(...);
bind(server, ...);
listen(server, ...);
client = accept(server, ...);
send(client, ...);
recv(client, ...);
closesocket(client);
...
So... my question!
This code runs in a own thread and should never ends (only when the user terminates the app).
After ther closesocket(client); when I want to re-listen to some incomming
connection request, have I to call only client = accept(server,...); or
listen(server,...); client = accept(server,...);?
What's the wright way:
WSAStartup(...);
server = socket(...);
bind(server, ...);
place <code>while (TRUE) {</code> here ???
listen(server, ...);
or place <code>while (TRUE) {</code> here ???
client = accept(server, ...);
send(client, ...);
recv(client, ...);
closesocket(client);
<code>}

Hi Daniel,
the usual way is the following:
First, start with
CREATE a socket object.
Then Call BIND (if you use MFC, CAsyncSocket::Create() will do that for you)
After this, set your ServerSocket LISTEN.
(and here is your loop...)
Then comes the connection handling,
that means you have to implement each acceptet connection in a own thread, if you want to have a multi connection server. After accepting (and creating your connection thread) go back.
Hope this helps a little..
Cheers,
Olli!

Hi Dear Developers,
From my application I'm executing a exe (by ShellExecute) and I want to do further processing once the program I executed is over. How will my application know when the program is terminated??
Thanks and Take Care

Dear friends,
I want advice regarding the efficient way of string searching. I got a text file in which about ten thousand english words are written (one word per line). All the words are arranged in alpabetical order.
Now you all people are aware of the intellisense feature of Visual studio. I also want to give like same feature in my application. There is a rich text box in my application. What i want is that whenever user type any word, a combo box automatically gets open and show all the words that starts from the first letter typed by the user, when user type second letter, the combo list decrease and only show those words having first and second letters same as what typed by user.
Letme give you example. If you have Win2k/XP, just go to start menu, and open the "Run" dialog box. Then type, c:\winnt\system32\s you will notice that as you type it, the combobox automatically expands showing the names of files or folders. The maximum files are in system32 and when you type any file name after typing system32\ then you may notice that how fast the operation of file sorting performed by the application to expand or contract the combo box.
I also want something like what i described above in my application. I have 10,000 words in text file. Now can anyone tell me that how can i efficiently perform this operation i.e how and when i load file. Do i need any appropriate STL container. How to perform string searching on the basis of characters typed by user e.t.c
Thanks.
