No, because I don't have any information to give a piece of code. What device are you trying to communicate with ?

Come on, Cedric, it's a universal serial device!

Well, that depends on the driver for your specific device.
If your device's USB driver acts like a serial-port then you need the ReadFile() and WriteFile() (just like in a serial port)
Otherwise, you'll have to refer to the documentation/spec of your device ...

Hi every body!
I've got one CString variable with value "Hello world" and now I want to write its value into one text file. what I have to do now? I'm using Visual C++ 2005 and my project type is MFC project. Thank you every much!

what about using std::ofstream ?
|

Probably you need WriteString method of CStdioFile, see here

In additional you can use of CFile class
|
|
|
|
|
CStdioFile already inherits CFile
|
|
|
|
|
Yeah
|
|

If you use std::fstream you need to manually cast the CString e.g.
#include <fstream>
#using namespace std;
...
ofstream out("filename.txt");
CString str("this is a test");
out << (LPCSTR) str << endl;

what about adding a out.close() at last ? 
also, your example works, but i wanted the OP to search a little by himself too... such easy code is not too hard to write when you're pointed in the right direction, what i did in my first reply
|

I had to leave something for the OP to find out - he only asked how to write the string to the file after all . I often don't call the .close() function as it happens automatically when the stream goes out of scope.
Actually I was hoping that someone was going to embarass me and tell me what I've been missing all these years writing explicit casts from CStrings to LPCSTR to use std::stream and also printf, TRACE macros etc.
I only posted as finding the need to explicitly cast can be a bit of a trick that is hard to find.

hum, i would have gone into C++ cast operators, like static_cast<LPCTSTR>(str) :p
but, was it really necessary to explicitely cast here ? i'm not 100%, but i have no compiler with me, so...
