Trying to figure out LB Workshop

[columbo]

I have had LB and LB Workshop for some time now but did not get to do much with it. Now that I am retired, I decided to give it a go and see if I could learn how to do something with it.

I thought I would start out with something simple and slowly expand it as I learn. Following the LB Workshop help file, I created a window with a simple menu containing 2 items. ("Do calculation" and "Exit"). The "Do calculation" pointed to [start] and the "Exit" pointed to [quit]. I compliled the window and it generated the following code.



'** Created by Liberty BASIC Workshop - 31/07/2011 11:53:28 AM
'** Yagi Antenna Calculator


[InitColors]
   'Please use default colors when possible.
   ForegroundColor$ = "Black"
   BackgroundColor$ = "White"

   True = 1 : False = 0

[WindowSetup]
   NOMAINWIN
   WindowWidth = 771 : WindowHeight = 650
   UpperLeftX = INT((DisplayWidth-WindowWidth)/2)
   UpperLeftY = INT((DisplayHeight-WindowHeight)/2)

[ControlSetup]
Menu        #main, "File", "Do Calculation", [start], "Exit", [quit]

Open "Yagi Antenna Calculator" for Window as #main
   #main "trapclose [quit]"
   #main "font arial 11"

[loop]
   Wait

[quit]
   close #main : END

[start]
       print "Yagi Antenna Calculator"
   Wait



When I run the program the window is displayed along with the menu. When I click on "Do calculaton" it should go to [start] which I thought would display the words "Yagi Antenna Calculator" but it displays nothing. If I select "Exit" from the menu, that seems to work fine and the program closes the window and exits.

Obviously I have done something wrong here but I'm not sure what? I thought print "Yagi Antenna Calculator" should be something very simple. If you use the print "Yagi Antenna Calculator" without a window it displays fine but doesn't want to do so in the window.

Any help with this?

Thanks

This is not really specific to LBWorkshop. It's a question about coding in Liberty BASIC. The "print" statement is overloaded, which means that it does different things depending upon the situation. A simple statement like,

print "Hello, World!"

will be printed in the mainwindow, which is a console-type window that appears by default when you run a Liberty BASIC program. It is suppressed if there is a "nomainwin" statement anywhere in the code.

Your "nomainwin" statement should be removed if you want to print info to the mainwindow.

It would be better to print information to a textbox control or a texteditor control appearing on the window.

Thank you very much for the help.
Since I was using LB Workshop to create the program I thought that this would be the place to ask about it. Sorry about that.
