I'm currently working with a WPF application in which I need to select items from a tab control. I can't find any articles about the tab control.  When I used the SelectionItemPattern it tells me that it doesn't support it.

I can find the tab control  fine, however, I can't do anything with it.  Treewalker return null when I use it.  I just need a simple sample on how to use it since I can't find it in Microsoft documentation (e.g. select item from tab control and click it or select it.)

I'm at a loss for a lack of information on tab control and the info available seems to be old or misleading. Any pointers toward it is appreciated.

Some widget of the software I want to control by AutomationElement technique owns only TextPattern and ScrollPattern. But I want to change its value by program not inputing mannually. So, how could I implement this function?

The supported patterns is as attachment!

I want get current user logon and logout time and print them it to a Textbox. I am using VB.NET and SQL Server. Please guide me how to get this.

Thanks in advance.

Hello,

I'm using Windows 8.1 and Inspect.exe to view UI control information.  However, I'm unable to see the option to show the UI tree in inspect.  I can only see the currently focused item.

Is there an issue with Inspect in Windows 8.1 that prevents this?  I've tried running Inspect in admin mode as well with no luck.

Hi,

I have a requirement of getting bounding rectangle for a treeitem in a treeview. The treeview control used is a VB6 treeview (TreeView20WndClass).

I came across TVM_GETITEMRECT. But, it says that if wParam is true, it will get rectangle only for the text part and if it is false, it will get rectangle for the entire line that the item occupies in the tree-view control.

But, I want to get the rectangle the region including both text part and icon. I am unable to find a way for this.

Or is it possible to get the rectangle for the icon?

Any help is highly appreciated.

Hi,

I am working on 2 different projects related to GUI Automation. One uses UIAutomationClient & the other one uses UIAComWrapper. I have a vague idea that both provide accessibility to controls based on Interop.UIAutomationClient but there are few differences. For example, in my experience UIAComWrapper is very fast and it also provides ability to access controls through legacy IAccessible. There are other differences too that are related to control patterns. Sometimes UIAutomationClient gives different patterns for the same control while UIAComWrapper provides different patterns.

Here I may also add that I use UIVerify to analyze controls, which internally uses UIAComWrapper to access controls. I work on VS 2010. I want more information about UIAComWrapper. I see so much material about UIAutomationClient on internet but so little about UIAComWrapper. I need to know why/how UIAComWrapper is so much faster than UIAutomationClient while they internally use the same assembly? Why do these 2 show different control patterns? Why was UIAComWrapper introduced when UIAutomationClient was already there to serve the purpose.

Can anyone elaborate the differences between these 2 while they are used for the same purpose i.e. GUI Automation? or suggest me some helpful links.?

Hello, 

I am a developer of this device mentioned in the page below.

https://www.plus-vision.com/en/product/copyboard/n20/feature04.html#save02

We built the solution, called "Direct computer connection",
by that, our device can present the scanned image as a file in mass disk of the connected host PC in usb mass storage protocol.

But, after completing the latest windows update, "Windows 10 Version 1607 for x64-Based Systems",
We found the windows stopped fetching the latest sector data of mass disk, after our device informed the host PC with "NOT_PRESENT" in "TEST UNIT READY"command response once. (Before that update, it works well!)

Can you reply me asap?

Thanks

Screenario:

   When a pop up shows up , our tool tries to click the 'Yes' button by Invoke(). However , sometimes , a exception is thrown up .I want to know the root cause and the solution !!!

Regards, Neelakandan

I have implemented the Code-UI support for my custom control. It was working fine in vs2012,vs2013 but i can not assert my control when using the VS2015 enterprise version. 

The below code is the root code for triggering the provider for Coded UI assertion and playback, this code has been written in control WndProc method,

protected override void WndProc(ref Message msg)
{
    switch (msg.Msg)
    {
          case WM_GETOBJECT:
                msg.Result = AutomationInteropProvider.ReturnRawElementProvider(Handle, msg.WParam, msg.LParam, this.Provider);
                return;
    }
}

i have found some differentiation from the msg.WParam and msg.LParam value between VS2013 and VS2015 which was mentioned below,

VS2013                                                 VS2015

WParam – 1480                                      WParam – {0}

LParam – {0}                                          LPara – {-25}

Is this wrong, Please suggest me the solution.

Thanks,

I am developing UI automation for my control. The below code working fine in VS2012.

MyControl.PointToClient(p);

But this code not working in VS2013. It was throws an following exception 

Also i have used the below code to Invoke the control

public new Point PointToClient(Point p)
{
   if (MyControl.InvokeRequired)
   {
       pointToClientCallBack ptcb = new pointToClientCallBack(PointToClient);
       GetWindow().Invoke(ptcb, new object[] { p });
   }
   return MyControl.PointToClient(p);
}
delegate Point pointToClientCallBack(Point p);

after i invoked my control, InvokeRequired property is in true.

So, can you please suggest me the right way to solve this problem.

Thanks,

Dear Team,

   The matter is that, we've developed an WPF application on MVVM design pattern using prism.  Our entire application has been developed .We needed to create the Test Automation framework for which we need to set a unique, permanent and stable property value  as identifier for all the objects (overall static and dynamic objects) so that the Automation framework doesn't brake over time in long run.

 Now, we don't want to use the default "Name" dependency property as object's unique identifier. So, we looked up to initialize cum bind the required "AutmationProperties.AutomationID" from XAML which is general in such automation scenarios. But, turns out that SmartBear's "Test Complete", test automation tool allowed to be used, is not able to locate any property with this name at all which we can configure as unique id.

   Finally, I found a dependency property "Uid" in place of "AutmationProperties.AutomationID" to serve the purpose which the tool is able to locate. 

Would you be kind enough to advise if we are in right direction!What options do we have to effectively populate this property for each and every object in all the Views that we have other than from XAML as we have near around  50-60 Screens.

I observe an illogical behavior of TreeWalker for filtered trees. Let us assume that we try to find all buttons in some application window using walker.  So we create a walker with the corresponding condition, something like:

VARIANT prop;
prop.vt = VT_I4;
prop.lVal = UIA_ButtonControlTypeId;
CComPtr<IUIAutomationCondition> type_condition_ptr;
automation_ptr->CreatePropertyCondition(UIA_ControlTypePropertyId, prop, &type_condition_ptr);

CComPtr<IUIAutomationTreeWalker> walker_ptr;
automation_ptr->CreateTreeWalker(type_condition_ptr, &walker_ptr);

And then walk the sub-tree for app's window (wnd_ptr):

IUIAutomationElement* child_ptr;
walker_ptr->GetFirstChildElement(wnd_ptr, &child_ptr);
while (child_ptr != NULL) {    walker_ptr->GetNextSiblingElement(child_ptr, &child_ptr);
}

On practice GetNextSiblingElement() returns not only buttons of wnd_ptr's subtree, but buttons from some other (not all) apps sub-trees.

It seems that the hierarchical structure of UI tree is not counted. Is that intended logic or bug? If it is the intended logicthen how to use the walker with the condition filter for sub-trees?

UI Automation documentation recommends to "make all UI Automation calls from a separate thread" (seehttp://msdn.microsoft.com/en-us/library/ee671692%28v=VS.85%29.aspx)

However it says nothing about whether it should be the only thread or multi-threaded access is also possible and safe.

So, I have 3 questions:

1. Is it OK to access UI Automation API from multiple threads? Can I for example get a IUIAutomationElement in one thread and pass it to another thread for further usage?

2. Is it OK to access UI Automation from STA threads as longs as they do not attempt to add/remove event handlers? MSDN says "Using the Single-threaded Apartment (STA) model can cause problems such as preventing clients from removing event handlers from the thread.". Does this mean other uses of STA threads are OK?

3. If the above usage is safe which cases result in performance penalty?

Thanks.

Hi!

I have a list of WinListItem. Each item has a text and an image. The image represents a green check or a red cross. I need to access to this image to know if the UI is displayed in concordance with business logic.

I have tried to get it via ControlViewWalker because from what I understand from the documentation, it should be available then as a child of the item.

public void A()
  {
     var listItem = UIMapOptionsActivationWnd.UIFirstListItem.NativeElement as AutomationElement;
     WalkControlElements(listItem);
     // result?
  }

  private List<AutomationElement> result = new List<AutomationElement>();

  private void WalkControlElements(AutomationElement rootElement)
  {
     AutomationElement elementNode = TreeWalker.ControlViewWalker.GetFirstChild(rootElement);
     while (elementNode != null)
     {
        result.Add(elementNode);
        WalkControlElements(elementNode);
        elementNode = TreeWalker.ControlViewWalker.GetNextSibling(elementNode);
     }
  }

But I am stuck here. Result has no element. I have tried the code using the WinList as the rootElement and it works to get the ListItems.

I also tried with a RawViewWalker, without more success. I will take any other solutions too!

Thanks!

Hi Sir,

In Control Panel > Hardware and Sound > Tablet PC Settings > Set tablet buttons to perform certain tasks.

There is error popup message but we really install button drivers on the system. There are 3 buttons on the tablet. (Power button, volume up and volume down). "Set tablet buttons to perform certain tasks" looks to launch Apps by buttons but how to do that? Is there any documents or reference link describes how to do that?

Thanks.

I had two collection one is column and another one is BaseStyleCollection and I had two forms. One form inherited another form.

public partial class Form2 : Form1
{

   public Form2()
   {
       InitializeComponent();
   }
}

public partial class Form1
{

   public Form1()
   {
       InitializeComponent();
   }
}

I have added my custom control in Form1 and add the (BaseStyles and columns) for my control in designer and BaseStyles and ColumnCollection attribute was DesignerSerializationVisibility.Contentand both are derived fromIList.

. Now i try to edit the childform in designer level and save the changes, i got the following error message

Stack trace for Columns collection:

Stack trace for BaseStyle:

This kind of changes occurring when make the changes for my control and save the changes in Form2 .

please suggest me. Why this kind of changes occurs? Is this reason for the exception? 

Thanks in advance,
