Hi all,
In my sdi application i have various threads running together and whenever some problem occur i close all thread and a modal dialog is displayed. Now my problem is if suppose 16 threads are running together a dialog box is displayed and when i click cancel or ok one by one 16 same dialog boxes are displayed. Now what i want is only one instance of that dialogbox should be displayed not those 16 instances.... how can i do this...
can anybody help me in this??
thanks in adavance

Simple Solution is use flag.
when you show the dialog for first time set the flag to true and then every time check for this flag before showing dialog. If flag is true don't show the dialog..
I hope that makes sense.

Hi ,
I developed an VC application which communicates with my hardware
with baudrate 1,15200.
I observered that my application takes much time to transfer the data,
when compared to Hyperterminal.(probably 10 times)
Is it because of my coding problems or problem with windows application?
Do I need to do optimization.But still i dont think i can increase the speed,
by almost 10 times.
Why hyperterminal is taking lesser time?
Please clarify.
Regards,
Sunil Kumar

You are most likely using non-overlapped mode.
The consequence of this is that the driver only handles one IRP at a time.
This means that if you've issued a read request with a call to ::ReadFile(), the driver will be "blocked" until the read request times out and a write request can be handled. How long time it takes depends on how you've set up the comm timeouts with a call to ::SetCommTimeouts().

yeah, im using non overlapped mode only.
I read that overlapped mode will have many overheads.
Which mode is efficient??

What kind of overhead and what would be the impact?
Forget about that. There might be some kind of overhead in theory, but in practice this overhead is presumably in the nano-/micro-second scale. Compared to calls that block for many milliseconds or even seconds, the possible overhead that is added by the use of overlapped I/O is ridiculously small.
In short: to be efficient you have to use overlapped mode.

You must be able to make that out from OSVERSIONINFOEX[^] structure that you pass on to GetVersionEx(). Please search for examples.

i have one vc++ project.I want to create linux executable from that vc++ project.how i do that.

Depends a lot of what you are doing with your sources. Is it a GUI application done with MFC ? If yes, then forget about it, MFC is windows specific.
If it is a console application and if you are using only standard C++ stuff, then you would need a specific compiler to compile for linux.
Converting existing code into cross-platform code is not trivial, it is best to take that into account directly before starting to code (and to take care of using only standard functions or to make sure that the correct versions of functions are called depending of the platform, using some #define).

You must be load your icon with LoadIcon and then use of SetIcon.
|
|
|
|
|
Open your <<FileName>>.rc file (in view code mode) and rename the icon name with your own icon name. In order to do this,look for IDR_MAINFRAME in that file.The path of the default MFC Icon would be res\\<<File_Name>>.ico. Change the path to your need and copy the new icon into that particular path.

struct classroom *croom;
};
struct student *stud = new student();
stud->croom = new student :: classroom();
