More tipps

Make it so :

Code: Select all

mbox_button_ok=ButtonGadget(#PB_any, 10, 110, 70, 30, mbox_button_ok_text$)

; Not so
ButtonGadget(#mbox_button_ok, 10, 110, 70, 30, mbox_button_ok_text$)

Add ever to the Dec part EnableExplicit for modules
Primary you should use ever EnableExplicit, for each code

Create the icons self with PB graphic functions
Its not a good idea for preload this little and simple icons

Instruction/Procedure: Debug()

Example:

Code: Select all


Define x.d = 10
Define y.d = 0
Define a.d = 0

y = x / y ; Works correctly.

;a = 1.0 / a ; Invalid memory access.

; the problem is that you have to convert the float to
; double again because the result variable a is double. :)
a = ValD(StrD(1.0)) / a

Debug("y: "+y)
Debug("a; "+a)

Please Pedro, your examples are not helping anyone here. Worste, your code on Enumeration is just plainly wrong, you don't even use the enumeration feature as you affect number to every constant. I would suggest to relax, learn how to use PureBasic and then come back with posts which are actually useful for the other users on this forums. Thank you.

Locked as you continue to post non-senses (just by the time I wrote my post which is pretty incredible

).
