Converting from char[] to tstring

[wfroelich]

I have an application where I am querying a modem over a tcp socket. I can receive the data from the modem as expected into my char[1024] buffer but am having trouble then converting it to a tstring.

I am seeing some extra characters returning now (after a firmware upgrade) that I suspect are multi-byte characters which then screwup my checking routines.

Here is what I am doing currently

retString = (std::tstring)( (CString) recvBuf);

is there a better way to ensure if multi-byte characters are in the buffer they are handled correctly?

Hi,
I am not sure whether I have understood you.

But about multibyte data how do you know that they are multibyte. another thing is whether they are multibyte or not you will get them as single byte(8 bit). The reason is you have defined buffer as char (signed byte). if you have "私" char. Shift-JIS will return 2 bytes for it and char buffer will store this two bytes as two different bytes. not only this I know these bytes will be meaningful if i use Shift-JIS encoding only not any other encoding.

Let us know if you know anything about these or if I am wrong.

Best regards,
Johny

retString = (std::tstring)((CString) recvBuf);

Tell me again how this cast converts a recvBuf (whatever type that is) to a CString that is then converted to a tstring?

Also, tell me how tstring is part of the std namespace.

If you can do that, your question will be answered.
