Embedded in the source. The code is based on scalion's alias Nicolas Rey's tests.

Quote
The program consist in 4 test :

Test 1 "Init" - Initialisation of 10000 item of string array with a letter followed by numbers.
Test 2 "Swap" - Swap all items one time with another (not sorting) ->  49 995 000 swaps.
Test 3 "Mid" - Concat each 9999 first items with 2 parts of item+1 : mid(a(i+1),2) + mid(a(i+1),1,1)
Test 4 "Sort" - Sort ascending the array.

Convert binary file to dq 123, 456, 789...
« Reply #186 on: April 12, 2022, 11:24:18 PM »
Just for fun :biggrin:

include \masm32\MasmBasic\MasmBasic.inc         ; download
  Init
  MbHexDumpLen=819200           ; let's be generous (default is 8192 bytes)
  Let esi=FileRead$(CL$())      ; read the file supplied in the commandline
  FileWrite "~testTmp.asm", HexDump$(esi, LastFileSize, dq)     ; use QWORD format
  ShEx "~testTmp.asm"           ; open in your IDE
EndOfCode


Usage: drag any executable (any file, actually) over bin2dq.exe

Output:
Code: [Select]

.code
; FileWrite "test.exe", offset hdStart, hdBytes

P.S., to test your result, you can use, for example:

Code: [Select]
include \masm32\MasmBasic\MasmBasic.inc
include ~testTmp.asm

  Init
  FileWrite "bin2test.exe", offset hdStart, hdBytes
  Launch "bin2test.exe"
EndOfCode

If you prefer pure Masm32 SDK for testing, use this:

Code: [Select]
include \masm32\include\masm32rt.inc
include ~testTmp.asm

.code
start:
  invoke write_disk_file, chr$("bin2test.exe"), offset hdStart, hdBytes  ; re-create the exe
  invoke WinExec, chr$("bin2test.exe"), SW_SHOW
  exit
end start

Buttons
« Reply #187 on: August 15, 2022, 06:22:16 AM »
Attached a program I am just working on, with several different kinds of buttons.

What is interesting: It behaves differently on Win 7 and Win 10. On the latter OS, some of the buttons receive up to 8 WM_PAINT messages in a row. Something is seriously wrong, and I am trying to find out what. It might have to do with a different behaviour of the CDDS_* messages, but I am not yet sure. I will keep you posted.

Thanks, but what I posted in the Campus is not supposed to act like a button exactly. It behaves like I intended it to.  :cool:

Well, that's OK. There's no law that says you can't make a static control behave enough like a button to suit your purposes. You won't get a knock on your door in the middle of the night from the Coding Police.

This grew quickly, the source is now a whopping 149 lines :biggrin:

Version 3 has a tooltip, knows about 2**3=8 and accepts PI as first parameter. Enjoy :biggrin:



P.S.: Binary result and bit descriptor for e.g. 123*456 look like this:

1101101100011000
5432109876543210

It can be helpful to see which bits are set.
