Re: How to create constants automatically?

A constant is just a macro with a hashtag. Once defined, it is replace everywhere during the compilation and is not present anymore in the final executable. I think at this point the discussion is closed. When you want to define a constant from another file (during compilation), you can use IncludeF...

Re: What variable type is "?" for CatchImage?

The second argument in CatchImage() is just a memory address. The ? operator is used to receive the memory address from a label: *Address = ? Label CatchImageEnhanced(#GLOBAL_IMAGE_POPUP_EDIT,?popup_edit,"Can't load image.") Procedure CatchImageEnhanced(MARCOAGPINTO_gadget, *Buffer, MARCOA...

Re: Sound channel not working properly

The channel is not linked to the sound, it's allocated dynamically (you can define a max number of channels in InitSound()) Ahh, that's a new feature, never saw this. It is also not visible in the online documentation: InitSound() Does this mean, if I use InitSound(16), I have only 16 channels in t...

Yes, that's also my opinion.

What I was meant was, the returned channel number do not have to be unique, because it is connected to the sound number as well, or am I wrong?

Re: Sound channel not working properly

The number of the channel is not a global parameter. Each sound number has his own set of channels in which the sound is played. Therefore, Pure Basic functions like PauseSound need the sound number as well as the channel (and not only the channel). If you play #SND_EARTH_CITY, #SND_CONSTRUCTION_LOW...

Re: LoadImage crashes on faulty BMP-image

But that mean the compiler should check for 1- Bad format 2- Bad image header magic number 3- No image but image extension(Bad guy idea) And maybe more Not the compiler, but the function LoadImage. Yes of course, that's the task of the function not of the user. Otherwise I have to write my own load...

No. A language function should never crash, because of incompatible input data. (LoadImage, LoadSound, LoadSprite, etc.)
A language function should return 0 is such cases, but not crash.

It is some kind of security risk.

Re: What is the usecase for BeginVectorLayer()/EndVectorLayer()

I use BeginVectorLayer() when I want to draw a set of overlapping figures in a half transparent way.
Without a layer, the individual figures would also blend each other.

Re: Revised Chr() & Asc() for UTF-16 surrogate pairs

I think your last version is the slowest due to several calls to other procedures. When we talk about speed, than we should avoid division of $400: Procedure.s _Chr(Unicode.i) Protected String.s{2} Protected *Long.Long = @String If Unicode < $10000 *Long\l = Unicode Else Unicode - $10000 *Long\l = ...

Thank you very much!
Actually, I did a mistake. PeekS only needs to read 1 character.

Code: Select all

ProcedureReturn PeekS(@high, 1, #PB_Unicode) + PeekS(@low, 1, #PB_Unicode)

Just replace Chr() with PeekS(@high, 2, #PB_Unicode) and PeekS(@low, 2, #PB_Unicode).

Re: AES+Base64 encryption

Your code still mixed up byte length and character length. I know, for characters between code points 0 and 127 it is the same, but having a correct code prevents later errors when using higher code points. If you want to allocate memory for an UTF8-encoded string, you have to use: *Buffer = Allocat...
