Hi Dennis,
Now I can see the output. By the way , I guess this should be set in the project properties dialog, because in the dialog's Tool tab, highlights the "Debug" item in the "tool name" list, then deselects the mark of "Capture output" and "Output to build window", I have done this, but it seems not any affect to the output window, the print result still can be displayed in the build output window, would you please advise what are the effects of these marks? Thanks.
David
