When EV_BREAK event indication is received on COM port?Whether serial device connected with serial port gives an EV_BREAK event report when it lost its connection with PC serial port??
Now I want to monitor my serial device connected with serial port and give a immediate report when it lost its connection.So I want to set EV_BREAK mask on COM port and decide to break my program when conn lost.
Is it OK?
Thanks.

Hello,
The EV_BREAK event is not reaised when the connection is lost. You should try the EV_ERR event. Look here[^] for more info on serial events.
Breaks are some special action that some devices send across the network. It is sometimes used to determine which device is allowed to send data.
Hope this helps.

There no persistence COMBO box exist in Window MFC libaray. So you have to save it your own either in registry or a FILE and Display whenever needed

Have them written in a flat file when application is closing, And read them back to combo while initializing application.

Its simple...
Open the workspace and go to menu view->Class Wizard.
The following message will come
The ClassWizard database "yourprojectname.clw" does not exist. Would you like to build it from your source files?
CLick "Yes" and Dialog box will appear .Then add all the files which you want to generate and then click "OK"

Exactly where you stopped.. my problem begins.. All the files are listed .. I did "Add All" .. then i got a error messages saying ..couldn't open those files..
Which files should be regenerated.. OR ELSE TELL ME .. WHAT DOES .CLW CONTAIN???.. and why i couldn't add a memeber variable of a newly added class?

Follow these steps:-
1.First Close down your Msdev and restart you computer.
2.Delete .ncw,.plg and .clw files if any
3.Now try to add Member Variable or Member Function using Class Wizard. this time Class Wizard will create corresponding .clw .
4. if step 3 fail, you have to manually add the Variable!

Hi Alok.. (Sorry for spelling ur name incorrectly!)..
I borrowed a class that maintained the history in a registry (from codeguru articles).. here is the link..
http://www.codeguru.com/Cpp/controls/combobox/article.php/c4955/[^]
........
i don't know where exactly the values are getting saved.. but they persist even if i clear the combo box..
