The CPU consumed upon moving the thumb is approx 12-18. So is it much enough to stop this project in Autoit. I just want some reviews and what users think about this script. The above is just implemented with Vertical Scrollbar.
Thanks for you time :)

Hi,

Very nice example. The CPU overload is due to the Draw_ScrollBar function called multiple times for only one move (redrawing the scrollbar 20 times in less than one sec).

I see a possible improvement: shift the code that returns the same thing each time to the startup function and avoid the redraw if it's not necessary.

Br, FireFox.

Tried many a times, but upon declaring the local variables( of function Draw_ScrollBar) to global, Autoit crashes on my computer. Edited by PhoenixXL

I don't know why the scrollbar is not visible on the start up, however the idea is here.

Draw the scrollbar only if there is a move, this can be much improved.

tony, this topic has no relation with marquee

I guess it would be better if we would just draw the required part that is if the user clicks the thumb, the thumb is only updated rather than the whole bitmap.

The graphics object could be updated in every resize message. Lets find out where it goes

Thanks for the suggestion firefox.

My code:

PredictText: Predict Text of an Edit Control Like Scite. Remote Gmail: Execute your Scripts through Gmail. StringRegExp:Share and learn RegExp.

Run As System: A command line wrapper around PSEXEC.exe to execute your apps scripts as System (LSA). Database: An easier approach for _SQ_LITE beginners.

MathsEx: A UDF for Fractions and LCM, GCF/HCF. FloatingText: An UDF for make your text floating. Clipboard Extendor: A clipboard monitoring tool. 

Custom ScrollBar: Scroll Bar made with GDI+, user can use bitmaps instead. RestrictEdit_SRE: Restrict text in an Edit Control through a Regular Expression.

Updated the example with a PIC control.

Increased the sleep in the ThumbMove,

made the local constants as global variables

CPU usage is reduced by 25%

      Just press the lmb and move your mouse. When lmb is released you can adjust the size of the window by dragging the white rectangle to any direction. Rmb will move the marked area.
      Press ESC to get the coordinates of the marked region.
      If you have any improvements, please post it here.

      Need an advice about what UDF for work with ZIP best use nowadays.
      By Tersion
      Here the this wiki page with list of available UDFs for data compression. For my tasks I only need ZIP support, so I started looking at pure AutoIt UDFs without any 3rd party dlls. And found out that most of available realizations uses standard ("native method") Windows dll - "zipfldr.dll". So for now I chose ZIP UDF by wraithdu. I've tested it on Windows 7 (x64) and it seem works fine. But here the comment from another topic where user says that Windows 10 discontinued support of "zipfldr.dll". Now I confused. I don't have around any Windows 10 machine to tested it. So maybe someone could confirm or deny that? Or maybe would better to switch to UDF with 7zip dll?
      I need an advice...

      Here is the bare bones of a UDF I have started work on.
      Mostly just a proof of concept at this stage, and still need to add some functions and dress the UDF up a bit ... to look like a UDF ... though it has my own distinct styling, especially as I have never really developed a UDF before now .... used plenty and modified plenty though. I've even invented my own UDF variable naming convention, which I am sure some of you will be aghast at. I work with what feels best for me, but others are free to adapt if they wish.
      The idea is to emulate the simplicity of INI files, but gain the benefits of SQL.
      Two scripts are provided.
      (1) The UDF, a work in progress - SimpleSQL_UDF.au3
      (2) An example or testing script - UDF_Test.au3
      Another first for me, is creating a 2D array from scratch, never done that before, that I can recall ... never had a need, and even for 1 dimension arrays, for a long time now, I have just used _StringSplit to create them. So I needed a bit of a refresher course, which my good buddy @TheDcoder assisted me with ... not without some angst I might add. LOL
      SimpleSQL_UDF.zip  (12 downloads previously)
      (I have now completed all the functions I intended to. My next update will be a big improvement, bringing things more inline with my latest INItoSQL DB program changes.)
      Program requires the sqlite3.dll, not included, but easily enough obtained.
      Hopefully the usage is self-evident ... just change the Job number variable in the UDF_Test.au3 file to check the existing functions out.
      Enjoy!
      P.S. This is also related to a new program I have just finished and uploaded - INItoSQL DB

      Drawing To Window/Screen
      By badcoder123
      I was looking around the help file and I came across _GDIPlus_GraphicsDrawRect and _WinAPI_DrawLine and I seem to be having the same "problem" where every time it draws into a window and you lose or gain focus it has to redraw itself. Is there anyway around this? 
      #include <WindowsConstants.au3> #include <WinAPI.au3> #Include <GDIPlus.au3> _GDIPlus_Startup() Run("notepad.exe") $hWnd = WinWait("Untitled") $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hWnd) $Color = 0xFFFF0000 $hPen = _GDIPlus_PenCreate($Color, 2) For $i = 1 To 10 _GDIPlus_GraphicsDrawRect($hGraphic, 200, 200, 25 ,25, $hPen) ToolTip($i) Sleep(1000) Next _WinAPI_RedrawWindow($hWnd, 0, 0, $RDW_INVALIDATE + $RDW_ALLCHILDREN) _GDIPlus_GraphicsDispose($hGraphic) _GDIPlus_PenDispose($hPen) _GDIPlus_Shutdown()
