Streamlining your code

Chapter 6 - Remove radio buttons

- StPendl StPendl Oct 29, 2011
This step now gets rid of the radio buttons, which are now obsolete due to the implemented color pick selection.

We only have to remove all the definitions for the radio buttons and consolidate the mouse and radio button event handlers into one.

To consolidate the event handlers we replace:
SUB MouseClick Handle$, PosX, PosY
    RBhandle$ = Left$(Handle$, Len(Handle$)-1); "r"; Right$(Handle$, 1)
 
    #RBhandle$ "set"
 
    call SetBandValue RBhandle$
END SUB
 
SUB SetBandValue Handle$
    ' parse handle of calling control
    Band = val(Right$(Handle$, 1))
    ColorName$ = Mid$(Handle$, 4, Len(Handle$)-5)
 
    ' get position of color
    FOR i = 1 to 10
        if Colors$(i,1) = ColorName$ then exit for
        if i < 4 then if Tolerances$(i,1) = ColorName$ then exit for
    NEXT

With the version to parse the graphics box handle:
SUB MouseClick Handle$, PosX, PosY
    ' parse handle of calling control
    Band = val(Right$(Handle$, 1))
    ColorName$ = Mid$(Handle$, 4, Len(Handle$)-4)
 
    ' get position of color
    FOR i = 1 to 10
        if Colors$(i,1) = ColorName$ then exit for
        if i < 4 then if Tolerances$(i,1) = ColorName$ then exit for
    NEXT

The complete code now looks like this.
