Can anyone provide me information about whitebox testing tools for Visual C++?

I couldn't find the right information about white box testing for vc++ application so thought of taking help from CP.

Wow, do you really want to write white box tests for Visual Studio?

whitebox testing is my clients requirement. I am deseprately looking for tutorials and tools. I am very confused to write test stubs/drivers for vc++ code. It would be very helpful if you can provide me some info about whitebox testing in vc++.

better would be function testing using you demo project!

Does function testing require communication between demo project and main project?

Hi.. I am writing a RS-232 application with one worker thread. Please tell me what is the best method for invoking the AfxBeginThread. My ideas are,
1. Using SetTimer() method handle it in OnTimer
2. While(1) which is infinite loop
I thought both these methods are not efficient enough. Please tell me any other method for invoking AfxBeginThread.
Thanks in advance

Why do you need multiple AfxBeginThread calls (maybe I haven't got you?)?

I have a file to be sent over serial port. So every time I am reading that file using a structure and sending. For this I need to call AfxBegingThread till end of the file.
Thank u..

 Are you sure you really understood the concept of threads ? You need to call AfxBeginThread only once. Then in your thread function, that's where you will send the file over the serial port.

you need to call AfxBeginThread for each thread you want to create ? no ?
if I want to create 50 threads, I should call it 50 times ?
Watched code never compiles.

I just can see your 47th thread handling the 47th character to be sent over the serial line...

I only have 42 threads.

But your process is still alive so you are going to reach soon 47.

making a RS 232 stabil is a hard job.
Consider writing a write and a read thread in your App. So you a 3 Threads.
The best way is with events like
while( ::WaitForSingleObject( hAbort, 0 ) )
{
}
there is also WaitForMultpleObject()

this one looks more plain but often it is better to adapt:

You call (i.e., invoke) it at the moment you are ready for a secondary thread to exist. Instead of polling the serial port for data, you could let it tell your process when something is ready to be read, like:
HANDLE hCom = CreateFile("\\\\.\\COM1", ...);
...
AfxBeginThread(ReadThread, this);
...
UINT ReadThread( LPVOID p )
{
OVERLAPPED ov = {0};
ov.hEvent = CreateEvent();
while (! bDone)
{
if (! ReadFile(hCom, ..., &ov))
{
if (WaitForSingleObject(ov.hEvent, INFINITE) == WAIT_OBJECT_0)
{
GetOverlappedResult(hCom, &ov, ...);
}
}
}
}This is very simplistic and I've omitted a lot of details, but hopefully you get the general idea.

I am not able to understand your design, do you want to have worker thread active all the time and do you want to create workerthread everytime request came

I am fully confused.. Again I am explaining you...This is my problem.
I have a file(let us say 5MB size). I need to send this file over serial port to a client.
As I can't send whole file at a time, I am reading the file into a structure(let us say 50 bytes), and sending.
After receiving 50 bytes of data the client will send back some acknowledgment. If acknowledgment is proper, I will send the next 50 bytes of data. Otherwise I will send the previous 50 bytes of data.
So this cycle repeats until the end of the file.
Now tell me how can I proceed. Am I going in a right path.
Thanks in advance

Sounds like it. I would opt for synchronous communication so that the "send" and "receive" packets match up. Asynchronous communication would allow them to happen concurrently.

#include <iostream.h>
I want to print the "helloworld" but it print "hell" ,why??
void show( char str[])
{
for (int i=0; i < sizeof(str)/sizeof(str[0]); ++i)
cout << str[i];
}
int main()
{
char str[]="helloworld!";
show(str);
return 0;
}

Because the size of a pointer is 4. Try strlen() instead.

'str' is a pointer.
sizeof a pointer is 4 (on Win32). so you get four characters: h,e,l,l.
if you want to get the length of a character string, use strlen.

}
This code is the same as this:
void show(char *str)
{
for (int i=0; i < sizeof(str)/sizeof(str[0]); ++i)
cout << str[i];
}
The array decays to a pointer. The size of a pointer is 4 bytes and the size of a char is 1.
