WinEventHook SYSTEM_DIALOGSTART never raised

Thu, 04 Sep 2025 09:09:16 +0000

Dear Sirs,

it seems that event for starting system dialog #32770 is never raised (see sample script below).
Only event for dialog end is catched.
I'm trying to get the selected path of choosen file(s) after hitting button (Open/Save/SaveAs ...) on the system dialog cn:#32770. Therefore I try to use a general Hook but DialogEnd message seems to be too late because window might be already released.
My idea was to start a timer to detect changes of path value (cn:#32770, id: 41477) at DialogStart and stop timer later after DialogEnd is raised - but without luck till now.
If anyone has an idea how to implemente such a hook to catch the user selected filepath, please let me know.

Code:
// script "TestEventHook.cs"

using Au.Triggers;

script.setup(trayIcon: true, sleepExit: true);

ActionTriggers Triggers = new();

  new WinEventHook(EEvent.SYSTEM_DIALOGEND, EEvent.SYSTEM_DIALOGEND, k => {

    var cf = new wndChildFinder(id: 41477);

    bool found = k.w.IsMatch(cn: "#32770", contains: cf);

    print.it($"SYSTEM_DIALOGEND found={found} => {k}");

  });

  new WinEventHook(EEvent.SYSTEM_DIALOGSTART, EEvent.SYSTEM_DIALOGSTART, k => {

    var cf = new wndChildFinder(id: 41477);

    bool found = k.w.IsMatch(cn: "#32770", contains: cf);

    print.it($"SYSTEM_DIALOGSTART found={found} => {k}");

  });

Triggers.Run();

UI Element Finder Dialog Closes Unexpectedly

Mon, 24 Mar 2025 01:27:20 +0000

In the CapCut software (latest version), when using the "Find UI Element" dialog in the navigation window to retrieve element properties, the dialog closes unexpectedly.
Steps to reproduce:

Press Shift + F3
Then press F3

The dialog will exit abnormally. Below is a demonstration:
https://download.ru/files/NxlZT8oz

TIP:
In the latest version of CapCut, the controls in the navigation window and the main application window are now hidden, making it impossible to retrieve control properties. Could this be the reason for the issue mentioned above?

Another Issue1:
Although the Shift + F3 hotkey can switch to an alternative element detection mode, for many controls, even when they are recognized, their properties cannot be retrieved. I have to manually select the "UI Automation" option and then press F3 again to get the control properties.
Therefore, I suggest that when I press Shift + F3, the "UI Automation" option should be selected automatically. Pressing Shift + F3 again should deselect this option.

Another Issue2:
When the "Add to path" option is selected, if I want to retrieve the "navig" property value of a specific control, the control must be in an unselected state. Otherwise, the property value cannot be obtained. This is often inconvenient. Below is a demonstration.

b.R.Add(ImageUtil.LoadWpfImageElement) show error and hang the program Version 1.9.0

Sat, 22 Mar 2025 04:04:29 +0000

This code create error everytime, even when I paste it in, only after updated to version 1.9.0

Code:

It also show an error message window, that make program hang when clicked

Changing an AutoText and compiling does not update

Sat, 19 Oct 2024 14:15:43 +0000

I think this has been introcued with one of the recent updates...

When I update the definition of an AutoText (or add a new one) and Compile, it isn't effective. I need to exit LA and start it again.

(Did not test with the other types of macros)

After updating the LA portable version, it won't start.

Sun, 29 Sep 2024 09:42:54 +0000

I updated the LA portable version using the configuration shown in the image below, but now LA won't launch; the window flashes and then closes immediately.

https://i.ibb.co/1vscF59/A.jpg

My goal for the update was to update the .NET runtime, LA software, option settings, and the DLL folder, while the script documents didn't need to be updated.

nuget err

Thu, 08 Aug 2024 22:48:10 +0000

#1
It's not possible to install the NuGet package named spire.doc into a folder named spire.doc; an error occurs.
https://i.ibb.co/Tw5fdwM/AA.png

#2
I want to change the script role to a class file, but that option isn't available in the role selection list. Do I have to manually create a new class file? I remember that earlier versions of LA supported conversion in the selection list.
https://i.ibb.co/zVzxGRT/CC.png

#3
In the message box shown below, it would be more convenient if, after clicking the OK button, the Tools -> NuGet dialog box could open automatically.
https://i.ibb.co/hW3DJ5H/DD.png

#4
When switching to the bookmarks or breakpoints tab, the control box height becomes smaller. However, I don't have this issue on my other computer; the height remains the same. Additionally, sometimes there's a blank area between the file search box and the controls below it, which cannot be adjusted. This seems to happen after resizing the open panel and tasks panel. The blank area only disappears after restarting LA.

#5
With the text insertion point inside `spire.doc`, pressing F12 failed to open its containing folder.

Adding DLL reference doesn't work.
https://i.ibb.co/7rp2w9R/AAA.gif

In the LA portable version, sometimes the referenced path is added in the following format.
/*/ r data\doc\Main\dll\Newtonsoft.Json.dll; /*/

I think it should be added in this format.
/*/ r %dll%\Newtonsoft.Json.dll; /*/

Autotexts loses spaces

Mon, 22 Apr 2024 06:56:33 +0000

I recently (I think it started with 1.1.8, but I was too busy to look into it at the time.) noticed a problem with Autotexts: any texts that include one or more space characters "arrive" w/o the spaces.

For example:
tr["#mb"] = "Michael Baas";

prints: "Michael Baas"

or

tr["#pt"] = "C:\\Data\\MB Privat\\Michael\\Profil Michael Baas.docx";

prints: "C:\Data\MBPrivat\Michael\ProfilMichaelBaas.docx"

First Startup Issues

Mon, 08 Apr 2024 21:07:20 +0000

After numerous tests, whenever I cold start my project files for the first time, I encountered some issues:

1. Occasionally, a single mouse click would register as a double-click.
2. Sometimes, window movement operations would fail.

I checked the code but couldn't find any issues. These problems only occur during the first cold start; they don't reappear after the second time.

Addendum
Regarding issue 1, my click handling code is written within a class file, not in the main file.
It's akin to the problem described in the following link:
https://www.libreautomate.com/forum/show...4#pid37754

It seems that some operations written within class files are unstable; sometimes, I have to add a delay(200.ms;) before the first line of code in a method within the class.

3. The first line of my main file is as follows, its role is exeProgram, and it references a class file _Chrome3. If I modify this class file, do I need to click its compile button every time? If I don't click it, It seems that in some cases, this doesn't work.
/*/ role exeProgram; c _Chrome3; /*/

find UI element Smaller

This may not be a bug but rather some special cases.

find UI element Smaller feature:

1. It does not work on certain toolbar controls and can only be manually expanded.

2. It also does not work on certain right-click menus; even if the node is manually expanded, detailed information cannot be obtained because the menu is closed.
For 2: Is there any other way to obtain information about the menu items?

The cursor automatically jumps to the end of the line.

Recently, I've often encountered a problem. When I add parameters to a function, after typing a certain letter, the text insertion point jumps to the end of the line.

For example, in the code below, when I input the letter "l", the insertion point jumps to the end of the line. This happened several times, then suddenly returned to normal. There's no pattern to it, and I can't reproduce it.

var w2 = wnd.find(1, "ChatGPT - Google Chrome", "Chrome_WidgetWin_1").Activate();
var e3 = w2.Elm["web:LINK", "New chat",f].Find(3);
e3.MouseClick();
