Reading text within an app

[ElsePoem]

Hello! A pretty new programmer trying to do something somewhat simple. I have been trying to get a script that can read text on screen within an app. Upon detection of that specific text I wanted it to pop up with a MsgBox letting me know that the specific text has been sent! I’ve tried everything i could but to no avail.
(I hope this code pastes correctly since i’m on mobile)

Code: Select all

Loop {                                                  ; Start Loop
    if (WinActive("ahk_exe *program*.exe"))               ; program is open
        {                                               
        WinGetText, text, ahk_exe program.exe           ; Get Text from program if open
        IfInString, text, "Warning!"                  ; Check if text is Warning!
        {                                           
            MsgBox "Warning DETECTED!"               ; If so, stop app
            ExitApp                                     ; Stops app

Please don't be afraid to tell me that this is complete gibberish if you know any help for the solution

Welcome to this AutoHotkey forum!

Perhaps:

Code: Select all

#Requires AutoHotkey v1.1.33.11
#SingleInstance
winTitle := "ahk_exe Notepad.exe"
find     := "Warning!"
Process Priority,, B
Loop {
 WinWait % winTitle
 SetTimer Go, 200
 SoundBeep 1500
 WinWaitClose
 SetTimer Go, Off
 SoundBeep 1000
}
Go:
WinGetText txt, % winTitle
If InStr(txt, find) {
 MsgBox 48, Warning, Warning detected!
 ExitApp
}
Return

If you are new to AHK, I recommend using its current version, which is v2, instead of this older deprecated version that is no longer developed.

Thank you!! it works perfectly! However I think now it seems to just be a problem with the api of the app I'm using or I'm not inputting the correct file name into my code, will check it out now!

Window Spy will show whether WinGetText can retrieve the text.

I looked at what it was viewing and not as much as i was hoping for, I found “Chrome.ahk on github so maybe that can read more than what it can now

[mikeyww]

Probably. I doubt that you would have much luck with WinGetText in a Web browser. UI Automation is available, with scripts posted on the forum.

Ill go search for some! thank you!

It's fantastic that you're diving into programming! For text recognition within an app, consider using libraries like OpenCV or Tesseract for image processing and text extraction. Break down your task into smaller steps, and don't hesitate to seek help from online communities or forums for guidance. Keep persisting.
