Hi, I am new to GTK+ and I am using it to develop a little GUI app to
download some data through the parallel port of a pc.
I am using the WIN 32 libraries with Visual C++ 6.0 and so far so good for
the GUI part.
Now I am trying to use the GScanner from GLIB to parse my data and it is
working fine if I use a variable containing the text to parse.
The problem I have it's when I try to set-up the scanner to use a text file
This what I have done and I am getting the following message " test text:1:
error: unexpected end of file, expected symbol "
Can someone help me?
Thank you!
