Re: Copying CByteArray to a CString?

I second the idea of using CString::GetBuffer/ReleaseBuffer.

You may want to try this code, which seems to compile and work fine:

<code>
    CByteArray buffer;
    ... fill the buffer or something ...

    // Index for buffer looping
    int i;

    // Change 0x00 bytes in buffer to 0x01
    for (i = 0; i < buffer.GetSize(); i++)
    {
        if (buffer[i] == 0x00)
            buffer[i] = 0x01;
    }

    // Copy buffer content to a CString instance
    CString str;
    LPTSTR psz = str.GetBuffer( buffer.GetSize() + 1 );
    for (i = 0; i < buffer.GetSize(); i++)
    {
        psz[i] = buffer[i];
    }
    psz[i] = 0; // end of string
    str.ReleaseBuffer();

    // Show the string
    AfxMessageBox(str);

</code>

Note that we are just raw-copying the byte array content to the CString, but
you should be sure about the encoding of the text data stored in the byte
array (is this ANSI? Or UTF-8? Or some other code page?)
