It seems like calling this method makes my application freeze.
It is happening on Factory.AddPropertyChangedEventHandler call
https://github.com/JakeGinnivan/UIAComWrapper/blob/master/UIAComWrapper/Automation.cs#L127

Any ideas why is it happening and how I can fix it?
Thanks in advance.

Hello,
I have a mainTab(_tabControl) under this couple of child tabs(PageTabs) ,am able to keep focus and select the required tab but problem is not able to close that opened page tab,each tab is having close button but when i use UI verify,the page tab is getting identified but not 'x' button. i tried to see childs ,ascendants using treewalker but no luck,

can any one help me how perform action to close page tab using White/UIACOM Wrapper/UI Automation?
my application:
Windows form,Infragistics controls,

NOTE: here am using TreeWalker ,since using White framework am not able to identify tabs or Grids or menubar or trees. its because my application controls are using 3rd party Infragistics controls.

Hi Team,

I have an Diagnostic app, which is not able to identify the controls in it through Treeview walker, it wont even identify that window at from the list of windows.

From UI verify tool also it shows excption and on click of continue it shows, the exception from UIA verify tool is attached here for your reference : Attached UIAVerify-Error-Log.txt file

The developers of the tool told that that tool is developed and they told that "they render a Blazor Application using a WPF Blazor control".

So in UIAComwrapper wont identify blazor application? If we wanto to find controls in it how to use UIAcomwrapper?

Registering for StructureChangedEvents on the RootElement, with the TreeScope of Children will cause Windows Explorer to crash intermittently. I have been able to reliably cause a crash by either navigating between network drives in Windows Explorer, or more reliably by right clicking the desktop -> Personalize -> Desktop Background and clicking the drop down "Picture Position". The crash occurs at the same location every time no matter how it is reproduced in Windows Explorer, in DUI70.dll, with the same offset every time, with an AccessViolationException. When attached to Explorer.exe in visual studio, I was able to download the public symbols for DUI70.dll and when the exception occured the function that DUI70.dll was currently executing was "RaiseStructureChangeEvent". I was only able to view function headers and the rest of disassembly.

Is anyone else able to reproduce this and have some insight as to what may be causing it? This was tested on Windows 7. We do not have any Windows 8 or Windows 10 machines that are currently in use, so I am not sure if they can be reproduced on those operating systems.

Getting property accValue of IAccessible throws an error:
Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED))

using System.Windows.Automation;

public object GetValue(AutomationElement element){
            object patternObj;
            if (element.TryGetCurrentPattern(LegacyIAccessiblePattern.Pattern, out patternObj))
            {
                var legacyIAccessiblePattern = (LegacyIAccessiblePattern)patternObj;
                var iAccessible = legacyIAccessiblePattern.GetIAccessible();

                if (iAccessible != null)
                {
                    result = iAccessible.accValue; // ERROR HERE
                }

I have code that calls AutomationElement.FromPoint every second, and noticed that the unmanaged memory continues to climb and i couldn't seem to find a way to get it to release it's memory.

Hi to all!
I have a problem: scrolling for UserControl work for first step only, all next steps are ignore.
I do not get any Error in this situation.
How can I fix it?
Thank in advance!

On Application side:

        var aaa = new UserControl();
        aaa.Location = new Point(200, 0);
        aaa.Name = "BedSideReview";
        aaa.Size = new Size(400, 400);
        aaa.AutoScroll = true;
        this.tabPage1.Controls.Add(aaa);

        var bbb = new DataGridView();
        bbb.MinimumSize = new Size(400, 400);
        bbb.Size = new Size(400, 400);
        aaa.Controls.Add(bbb);

        var ccc = new DataGridView();
        ccc.Location = new Point(0, 400);
        ccc.MinimumSize = new Size(400, 400);
        ccc.Size = new Size(400, 400);
        aaa.Controls.Add(ccc);

On Automation side:

        var scrollPattern = GetPattern<ScrollPattern>(uiControl.GetCurrentPattern(ScrollPattern.Pattern));
        scrollPattern.ScrollVertical(ScrollAmount.SmallIncrement);

Uisng Treewalker ,i am able to get required row number from the grid but not able to select that row.

i have tried selection,invoke, and other pattern but everything is throwing error like un supported pattern.
myrow=2 //example
// to get row element)
AutomationElement rowElementToSelect = requiredGrid.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.AutomationIdProperty, myrow.ToString()));

// get row header
AutomationElement rowHeader = rowElementToSelect.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Header));

// invoke it (select the whole line)
//((InvokePattern)rowHeader.GetCurrentPattern(InvokePattern.Pattern)).Invoke();

Environment: Windows forms,Infragistics,.netframework 4,

Can any one help to get the solution for this scenario?

run without administrator privilege, the program looks normal, but the event is triggered with a delay 1-30s
