I want to share this simple code that allows to bypass DDE server, and receive live data from MT4/MT5 directly to your AHK script. See comments in the code below for details. 1) Get handle of the AHK script that will receive data from MT4 and store it in a separate file DetectHiddenWindows On AHK_HW...

I was confused about DDE protocol, due to my ignorance, I thought it was something else. After reading MSDN, looks like DDE is nothing more than just exchanging system messages (same as PostMsg + OnMessage). So one can write MT4 indicator that would post messages with last ticks directly to AHK scri...

it will be easier to write an EA directly rather than using AHK I need to get quotes for my existing AHK script. And MQL doesn't have all the functionality that I need. For now Im using Excel to get access to MT4 DDE server, but trying to get direct access. As a workaround, I wrote MQL indicator th...

Hi folks! Im trying to connect to DDE sevrver using AHK. Server that Im trying to work with is from MT4 (forex charting/data software), but I guess it doesn't matter, since all DDE servers probably work in same format. So, I found 2 DDE libraries here on AHK forum (attached below), and tried to use ...

evilC, thanks!

evilC, thanks!
Yeah, that' a good idea. I will just add SetTimer to wait few seconds before showing tooltip

Hi folks,
Is there a more lightweight way of checking if Ctrl/Shift/Alt buttons are pressed than GetKeyState()?
I have keys get stuck sometimes on my old PC, and since many keys need to be constantly monitored, I wonder if there is a more lightweight / non-intrusive way to check them.
Thanks!

Hi Noname,
GDIP itself is started only once in my script, I don't know yet what exactly causes the problems, but I think Helgef's suggestion:

Code: Select all

if Error := DLLCall(...) ...

will catch the perpetrator soon
Thanks again!

Noname, you are absolutely correct, - not using "Gui,new" fixes the problem.
Thank you for setting me on the right path!

BTW, should it be reported to Lexikos as a bug?

serg

Helgef, I really appreciate your help! Thanks!

serg

Noname, thanks for your input !
I'll try your code. Btw, I have this problem only on my other Win 7 machine, but not on Win 8.1

Check if the functions you are using sets ErrorLevel or the underlying windows functions sets A_LastError . If there is no image, maybe it doesn't have a width and height . Good luck Helgef, thanks for response! I have 2 suspect GDIP functions: Gdip_GraphicsFromImage(pBitmap){ DllCall("gdiplus\Gdip...

Hi folks! What is the fastest way to test if image created with GDIP actually contains image? When I create bitmap and copy image there from image file - it works 99% of the time, but occasionally GDIP function returns empty image (I mean it returns handle that doesn't contain any image). Since I us...

Hi, has anyone encountered this problem with GDIP: - top 25 pixels of GDIP-created Gui are "un-clickable" when Gui is inactive? I.e. if I create GDIP Gui, then activate some other window, then click on top 25pix of this Gui - it doesn't get activated. If I click below top 25 pix - it does get activa...

Guest3456, I ran your updated code, it gave me different results, traditional var assignments (without quotes) are the fastest :
4.884133
5.322768
4.117642
6.175888
3.612573
5.098961
So I guess PC setup makes difference here. I have Win8.1 64 with AHK 1.1.24

serg

That's interesting. I also added to the test comparison without quotes:

Code: Select all

if var = Hello World

It gave result about ~10% faster than the (case sensitive "if ==")-method - the fastest in your code above

@Almost_there "Gdip_ImageSearch" by MasterFocus is much faster than native "ImageSearch", - at least it used to be. I use it for reading text from screen. Althou your last post should probably be in a separate thread I actually meant something completely different from ImageSearch. Maybe a Shape se...

This is quite useful thread, I want to add few points: A) Regular vars are retrieved faster than array elements (in example below ~3 times faster): ar := [1,2,3,4,5,6,7,8,9] t1 := a_tickcount Loop, 1000000 q1 := ar[1]*ar[2]*ar[3]*ar[4]*ar[5]*ar[6]*ar[7]*ar[8]*ar[9] t1 := a_tickcount - t1 ar1 := 1 , ...
