What has chr(255) + "k" to do with clicking on the "X" / close button? How are they related? Extract of the FreeBASIC manual, keyword "Screen (Graphics)", paragraph "Other details": While in windowed mode, clicking on the window close button will add a keypress of Chr(255)&"k" to the Inkey buff...

And while I'm here, I'll give my usual "NOT is a unary operator, not a function" warning. Admittedly it's not likely to become an issue in standard use-cases, but don't come crying when NOT(a) - NOT(a) gives 2 * NOT(a). Explanation for beginners: - The parentheses are there to mislead, because they...

Some ideas to detect the graphic window state: Testing the current window position (x, y), in desktop coordinates, you can detect: - the minimize window state (x=-32000, y=-32000). - the maximize window state (always x=0, y=0), but it is not a test absolutely sure, because the position (0, 0) can e...

Ok now I see my problem.... BOOL: (Integer) -- normal return code for a dialog False = 0 True = -1 BOOLEAN: ( UBYTE ) False = 0 True = 255 So to make things equate the same, BOOLEAN should be changed to a BYTE I think not. Currently, most of the languages use the convention True = 1 and False = 0, ...

New button "Strike-through" in the post editor ?

In addition to buttons "Bold", "Italic", "Underline", it would be possible to have a new button "Strike-through" to better highlight the successive updates (author reviews)?

Whether there's any difference between BOOL and BOOLEAN would depend on how you define them respectively. I think BOOL is defined in the Win32 API as just an Integer, and TRUE/FALSE being 1/0 (so be careful of using NOT or comparing with TRUE). I don't know about BOOLEAN. "win/windef.bi" type WINBO...

Re: Recursive Sub calls, If statements, etc

To work around 'Gosub' / 'Return', you can use Asm blocks.

Anyway, this is no big deal, because if 'extends' is finally chosen (probably), the fiercest partisans of 'inherits' can always insert at the top of their source:

Here is another issue with "extends" that I couldn't articulate till I saw another example of its usage: cat extends animal In English, when you "extend" something, you build onto it in some fashion. The cat UDT does not extend the animal UDT -- the animal UDT remains unchanged -- the cat UDT only ...

Are there plans to complete the user-define type support by adding the ability to define static member data (in addition to the static member function)? Behavior: - When a member data is declared as static, only one copy of the data is maintained for all instances of the type. - Static member data ...

Yes, but you should also say: Why define a user-define type as scaling-type, whereas we use a single instance? - Define a user-type including 2 data and even perhaps 2 functions, just to create a single instance, seems excessive and wasteful! - You could use a 'namespace' block (which allows period...

@fxm: An option, but I don't like it. It would make sense if I had multiple instances of scaling_type. E.g.: * raw2scrn(raw, scale1) * raw2scrn(raw, scale2) But for only 1 scaling_type variable, using passing as function parameter seems odd. Yes, but you should also say: Why define a user-define ty...
