Hi, All, =20
I am trying to make a window with a "Run" botton. After click, it inport=
s text from a file and, after manual manipulation of the text data in th=
e textbox, it produces a graph using the text of the box. Then the graph=
will be displayed on the same window. It runs only on the first time I =
click "Run". When I click "Run" again after the first click, an error wa=
s returned basically saying the file reading pointer is at the end of th=
e file, so no calculation is performed. Can anybody give me a hint on th=
is=3F =20
Thanks a lot, =20
