Hi everyone,
I am currently finishing my vocational training. After this 3-year-phase I will be transferred to another department, which uses a different approach:
In my current department, most GUI-design is done with WinForms or VB6. The "new" department uses the MFC for most of its GUI-stuff, so I need to get into that ASAP.
That means I am pretty much relying on you guys to provide me with some pointers to sources where I can read up on GUIs with the MFC and the MFC in general.
Thanks in advance.
Cheers,
Sebastian

Why does ReadFile function hang after successfully reading a byte from port?
|
|
|
|
|
You must give more detail about the problem if you want help.

I wrote a program in Visual C++ to implement Serial Communication. The program compiles successfully and runs also. After initialising the ports, when a byte is written to the port, on one computer and is read on another computer (which is connected to the earlier computer) the code works. But when I try to read the port again the program simply hangs. The only way out is then to stop the debugger.
I used the initialisation code provided in a article posted on this site itself (the one written by Eshwar). But to implement read and write I only used the functions ReadFile and WriteFile respectively.

If there is no data coming on the port anymore and if the read timeout of the port is set to infinite, the ReadFile function will wait until data is received (thus it seems to 'hang').
To change this behavior, you can use the SetCommTimeout function.
But I suggest you to read a little more documentation about how serial ports work because you seem to lack some important informations there...
Hope this helps

Respected Sir,
I read your suggestion and tried setting the timeout to a lower value. I set it to the following values :-
commTimeout.ReadIntervalTimeout = 10;
commTimeout.ReadTotalTimeoutConstant = 10;
commTimeout.ReadTotalTimeoutMultiplier = 1;
commTimeout.WriteTotalTimeoutConstant = 10;
commTimeout.WriteTotalTimeoutMultiplier = 1;
Still no use. The ReadFile function makes the program hang. Please can you suggest some sample values.
Thanking you.

Still not enough information. It is well known that ReadFile and WriteFile both work. The problem must be in your code. Post some sample code.
It may be simply that you call ReadFile again when there is nothing for it to read; what if you send it another byte from the other computer?

In non-overlapping mode, when you call ReadFile, it will wait until it reads a byte at least. It also depends on the input size as I remember.
You really should not call ReadFile or WriteFile in your main thread, you better use another thread to do this, which will keep your program responding, and it is better to use proper time-out values for the port, so that ReadFile will fail after a certain amout of time if nothing is read.
Does that do any help?
this is this.

Use an ADO recordset with a query like
"SELECT * FROM [Table] WHERE [FIELD]=value;"

i doubt you code this directly in C++...

No, of course not! 
You use a recordset, (coded in C++) which needs a query string like the one I showed.

Hi
This is again a problem with thread. The thread is affected by programs running on the background. It is affected by the programs showing in the system tray. Is there any way to close all programs and processes other than my application and related processes and threads.
Help Me Soon.

EnumProcess and then Use WM_QUIT to kill Process other than you!

Hi Alok
See.. If I am setting the priority of the application process as a REALTIME_PRIORITY_CLASS in its OnInitDialog() function (if not in this function, where?) and setting the thread created by that application using SetThreadPriority() (calling in the thread itself) to TIME_CRITICAL_PRIORITY level , what would be the priority of the thread that I have created? Can any process or thread interrupt the thread I have created?
