FASM : play a wav file with assembly programming language.

... this source code in FASM will play a hexa file using a window with two buttons, see my comments to deal with 'how to do it' ... :

; sound player example , tested with tada.wav from windows os
; convert wav file with
; tomeko.net/online_tools/file_to_hex.php online tool
; to text from tool , then add 'db ' in the front of Sound.inc text file like this:
; db 0x52, 0x49, 0x46, 0x46,
; this : 0x52, 0x49, 0x46, 0x46, is header for RIFF WAV file format

FASM : writing on the screen with assembly programming language.

I haven't worked in assembly language for a long time. My favorite is FASM.

Here is an example of older source code that randomly displays some colored pixels.

If you change this line of source code, you will see that it is written directly on the screen from Windows 10:

invoke FindWindow,NULL,<'Random Pixels Screen'>

this is the result:

... using this you cannot be able to take a screenshot with Windows shortkeys:

invoke FindWindow,NULL,<'Random Pixels ...'>

This is the source code, if you want to test it:

News : Inkscape Is About To Revolutionize The Shape Builder | v1.4 Beta Update

Inkscape : Create an extension for inkscape.

You can create your own extensions in inkscape with all features you need to improve the working area.

One extension can have minimum two file: the basic Python source code and another file with the graphic user interface ...

The source code of Python file can be link with the G.U.I. source code type file INX.

The source code for python can be customized and this is the main reason is no need to add it here.

Let's see the source code for the INX file:
