I have searched a lot here on stackoverflow and googled as well but haven't find any working solution and i am a newbie btw.
I have a windows forms based application. I can launch it by custom Url Protocol myapp:// by Setting a Registery Key:
My App > shell > command > pathtomyfile/app.exe
I have added a hyperlink to launch application i.e
myapp://test123
and it launched app.exe just fine. Now how can i recieve the test123 as arguments.
So my question is:
How do I receive the test123 as a parameter in application?
Try this code:
For Each argument As String In My.Application.CommandLineArgs
... (Add code here to use the argument)
Next
You can use this i.e. in Form1.Load or Form1.Shown event.

I'm running a set of automated UI tests using Appium/Winappdriver on Windows 10. The test framework is compiled in Visual Studio 2017 using mstest.
The problem that I am having is with tests that use a right-click to open a context menu, then select an element from the resulting menu. Locally, it works. It also works on our remote CI/CD machine. However, it does not work for the other two developers on the project, and we've spent two business days fruitlessly trying to figure out why.
We have the same Windows version (Windows 10, version 1903), we have the same Visual Studio 2017 (we also tried it with 2019, no luck), we have the same monitor resolution (1920 x 1080), we are targeting the same .NET framework (4.72), we have the same WinAppDriver, etc.
Everything else works just fine. But when the UI Test reaches that context menu, the test fails with the error "An element could not be located on the page using the given search parameters."
I used the WinAppDriver UI Recorder to find the XPath for the element. We also used it on the other user's machine and confirmed that, as far as the UI Recorder is concerned, the path is identical on both machines.
The specific call that fails:
Session.FindElementByXPath("/Pane[#ClassName=\"#32769\"][#Name=\"Desktop 1\"]/Menu[#ClassName=\"#32768\"][#Name=\"Context\"]/MenuItem[#Name=\"" + itemName + "\"]");
The WinAppDriver call on my machine (success):
{"using":"xpath","value":"/Pane[#ClassName=\"#32769\"][#Name=\"Desktop 1\"]/Menu[#ClassName=\"#32768\"][#Name=\"Context\"]/MenuItem[#Name=\"New Location\"]"}
HTTP/1.1 200 OK
Content-Length: 125
Content-Type: application/json
{"sessionId":"8970FDC1-E869-4304-A87D-D8F2CB711EA2","status":0,"value":{"ELEMENT":"42.856234.4.-2147483646.8140.18614751.1"}}
and the same call on the other user's machine (fail):
{"using":"xpath","value":"/Pane[#ClassName=\"#32769\"][#Name=\"Desktop 1\"]/Menu[#ClassName=\"#32768\"][#Name=\"Context\"]/MenuItem[#Name=\"New Location\"]"}
HTTP/1.1 404 Not Found
Content-Length: 139
Content-Type: application/json
{"status":7,"value":{"error":"no such element","message":"An element could not be located on the page using the given search parameters."}}
Again, everything else works. Other UI tests that don't use the right-click context menus work just fine. It's only this particular area that fails.
What I've tried so far:
Using Thread.Sleep to force a long wait before making the call
Wrapping the call with a DefaultWait and polling it over a period of several seconds to see if the element becomes available during that time.
When the "An element could not be located" is thrown, retry up to a set number of times to find the element.
Lots and lots of double-checking to make sure we're both on the same version of the code, same libraries, same nuget packages, etc.
Trying a much broader locator ( Session.FindElementByName(itemName); )
The biggest head-scratcher is that when we check with UI Recorder, the element is there. When we check on my machine or the remote build machine, WinAppDriver can find it normally. But for some reason WinAppDriver can't find it on my coworker's machines.
This is a peculiar issue indeed.
I'd like to rule out the XPath selector as a potential problem here. Based on your syntax, it looks like you are using an absolute XPath. These can be extremely brittle depending on the circumstances. Not saying it's the root problem, but I would like to try a different selector to rule this out.
{"using":"xpath","value":"//MenuItem[#Name=\"New Location\"]"}
Using relative // notation tells your path to look anywhere on the page, rather than following a specific path down to the element itself.
Give this a try, and let me know if it helps at all.
For my application context menu is listed out of the DOM of actual application in inspect.exe. So switching back to desktop session after selecting the context menu worked fine for me.
var regressionChannelRow = labelProcessorSession.FindElementByName("5000");
Actions action1 = new Actions(labelProcessorSession);
regressionChannelRow.Click();
action1.ContextClick(regressionChannelRow).Perform();
Now creating a desktop session to get the "Stop" option from the context menu
AppiumOptions appCapabilities = new AppiumOptions();
appCapabilities.AddAdditionalCapability("app", "Root");
WindowsDriver<WindowsElement> desktopSession;
desktopSession = new WindowsDriver<WindowsElement>(new Uri("http://127.0.0.1:4723"), appCapabilities);
below is the context menu option which I need to select, remember to use desktop session here
var stopService = desktopSession.FindElementByName("Stop");
stopService.Click();
I've just replicated this issue. I was working on a test that I wrote last week, which was now getting stuck trying to find the context menu from a desktop session. I tried using various XPaths, searching by class name or just name, but it didn't seem to make any difference.
Eventually I tried closing Spotify, and that solved the issue! If you're experiencing this problem then try closing every application window possible.
I'm making an application with WebView control. And I want it to read local html file. But I can't find the right way to make it possible.
At first, I simply tried to use Navigate method and provide the file path in the "file:///~" format string as a parameter, but it didn't work.
https://learn.microsoft.com/ja-jp/windows/communitytoolkit/controls/wpf-winforms/webview-known-issues
This Microsoft page says that WebView control does not recognize "file:///~" protocol.
And it shows the 3 solutions to make WebView control to read local html files.
Use NavigateToLocal() method.
Use NavigateToLocalStreamUri() method.
Use NavigateToString() method.
I tried all of them, but each 3 have some issues that doesn't make it work.
NavigateToLocal method requires a RELATIVE path of the file (not the absolute path), relative from the application executable directory. So files in somewhere else from the application directory cannot be read by this method.
NavigateToLocalStreamUri method is not even implemented according to the page! I once tried it anyway, but it returned an exception and didn't work.
NavigateToString method can render the given html content string, but the external files like css, js, image files included by html codes cannot be loaded, so it does not provide a full function.
I found some sample of using NavigateToLocalStreamUri method and tried it by myself.
(VB.NET)
wvwMain.NavigateToLocalStreamUri(uri, New StreamUriResolver())
Public Class StreamUriResolver : Implements IUriToStreamResolver
Public Function UriToStream(uri As Uri) As Stream Implements IUriToStreamResolver.UriToStream
Return New FileStream(uri.LocalPath, FileMode.Open)
End Function
End Class
By this code, NavigateToLocalStreamUri method returns System.Resources.MissingManifestResourceException.
What I want to realize is very simple.
Using WebView control
Read local html file located anywhere on the local storage
And render the html file completely as an expected result
But I don't see the way right now.
I would appreciate your advises or helps.
The method NavigateToLocalStreamUri will not work. Please see https://learn.microsoft.com/en-us/windows/communitytoolkit/controls/wpf-winforms/webview-known-issues.
You have to use NavigateToLocal, but you will see a warning that it is deprecated. However, it does only work with relative paths. Is it possible for you to restructure your application so that you can use relative paths?
The NavigateToLocal method is the only way that I've found to call local HTML files in Microsoft.Toolkit.Forms.UI.Controls.Web WebView v6.0.
On Visual Studio 2019 Windows 10, the following VB.NET code works on my PC
Imports System.IO
Dim sFileName = Application.StartupPath & "/MyPage.html"
wv.NavigateToString(System.IO.File.ReadAllText(sFileName))
where wv is a WebView object.
I'm facing a problem on Mac 2016 Powerpoint. In my VBA module I need to run an applescript. As we cannot use MacScript anymore I followed RonDeBruin's explanation to use AppleScriptTask. My Applescript is working fine on his own but when I try to call it like this :
AppleScriptTask("hello.scpt", "myhandler", "hello")
With in my apple script
on myhandler(paramString)
say paramString
End myhandler
It gives me an error 5 - Invalid procedure call or argument
my script is placed in Library/Application Scripts/com.microsoft.Powerpoint is this path alright?
Thank you for your help
I know this is an old thread but I was receiving this error and the issue was the location of my AppleScript.
I originally had it under
/Library/Application Scripts/com.microsoft.Excel
and I should have had it under my Library
/Users/username/Library/Application Scripts/com.microsoft.Excel
I did get that error originally but now it works for me with your stated folder location but only after I rebooted my Mac and tried the same script with Excel:mac 2016 (I'm not sure which action is responsible for the success). Interestingly, I thought that since Microsoft is very protective of their trademarks that I originally thought that the folder name needed to be "com.microsoft.PowerPoint" but that did't work.
I have two page application and the main page is default is "MainPage.xaml" and the second one is "AddPerson.xaml" when user click a button on main page I want the app to take user to "AddPerson" page.
And I wrote following for the Click event of the button
Me.Frame.Navigate(System.Type.GetType("AddPerson.xaml"))
and I am getting the following error
An exception of type 'System.NullReferenceException' occurred in MedicineSchedule.exe but was not handled in user code
Additional information: Object reference not set to an instance of an object.
If there is a handler for this exception, the program may be safely continued.
I tried other method of navigationservice.navigate which I cannot find the class in VS2013 express at all. The only method available is Me.Frame.Navigate in my project, please let me know how I can get this simple thing to work.
If it was .net 2.0 I would simple called new form with form.lod or something similar.
This doesn't work?
this.Frame.Navigate(typeof(AddPerson));

Can a CommandParameter be passed to a Command in WinRT? How?
Actually, I may have misunderstood your question entirely. If you are talking about UI commands (commands that implement the ICommand interface) you can pass parameters when you call Execute. You can also test if the command and parameters are valid before executing the command by calling CanExecute.
As for passing a parameter as part of a Button binding, set the Command property equal to the command you want the button to execute and set the CommandParameter property equal to the parameter you want to pass.
Yes and no. WinRT applications can receive parameters through the Application.OnLaunched override.
The override receives an instance of type LaunchActivatedEventArgs which includes the arguments.
So it is possible to receive arguments, the question is more about how they can be passed.
Windows Store (WinRT) applications cannot be started from the command line. If a WinRT application is associated with a file type, it can be launched by calling ShellExecute on a file. Other than that, the application cannot be started directly.
It is possible to write C++ that launches a WinRT application using the IAplicationActivationManager interface and this interface can pass parameters to the launched application. So you could create a C++ launcher executable that could be called from the command line.
For more information on how to launch an application using this interface, see the following forum post:
