I am making a program in MFC.The main frame take the charge of moniting,if the specified event occured,a short message will be sent.At the same time,I will moniting if there is a new short message had come,if it had,I will do someting with the message.So in the situation above,what should I prefer?The timer or the thread? I am a newer in MFC.Thanks!

Your description is a bit involved. Could you please elaborate and clarify?

For example the program is used for sending a mobile short message when a button is clicked,at the same time, the backstage is used for checking if there is a new short message had come every three minutes.I mean how I deal with the backstage.Set a timer or make a thread?

Since the background operation have to be done in every 3 minutes, timer is inevitable. Your real concern is - which one to use? "Simple mfc message timer" or "thread + timer"? Well, my suggestion is, if your background operation is time consuming, go for Thread+Timer, or else simple WM_TIMER message will do, since it won't block the GUI.

Jijo.

CProgressCtrl for 64-bit ints

Does anyone know of a wrapper to CProgressCtrl that accepts __int64 values?

Best wishes,

Seeing how the progress control can only show progress one pixel at a time, and the win32 progress bar control already has a range of 0 to 65535 (a short) which is way more than could ever possibly be shown on a display screen, creating a wrapper to accept __int64 values would be fairly simple. Just a little bit of division to get the number into the proper range.

Can you make your range be between 0 and 100 percent?

Is it easier to create INI file in REGISTRY
then READ/WRITE TO it?

CPallini30-Oct-08 23:04

30-Oct-08 23:04

For your kind of application, the registry shouldn't be used.

Why cant i use registry????

can u tell me please....
im quite IGNORANT abt all these

CPallini30-Oct-08 23:26

30-Oct-08 23:26

Well, you actually can, but you definitely shouldn't.
The registry should be used for maintainig application settings (i.e. few data), not as application general data storage (i.e. big amount of data).

CREATE/READ/WRITE INI file

CPallini30-Oct-08 23:07

30-Oct-08 23:07

Reading and writing to a INI file it is very simple.
You can easily make a 'test' INI file, using, for instance the notepad, and then write to (or read from) programmatically.
Check out one of the articles I linked in one of my previous replies to see (in the source files) some sample code.

Yes i did check all those links....

thanks..it was helpful...
but it all tells abt WIN32 CONSOLE Application...

whereas i need.... MFC Application

CPallini31-Oct-08 0:00

For the purpose of read/write to a INI file, the fact it is negligible.

BTW are you able to code a very simple MFC application?
