ToastActivatorCLSID missing from AppUserModel

im an currently following this guide to add windows toast notifications to my app.
https://learn.microsoft.com/en-us/windows/uwp/design/shell/tiles-and-notifications/send-local-toast-desktop
i need to create a shortcut that contains the System.AppUserModel.ID and System.AppUserModel.ToastActivatorCLSID.
now the website says to just have your installer create this and they recommend using WIX. which is fine but i would rather just create the shortcut from C# code.
so there is this example that creates the shortcut via C#.
https://code.msdn.microsoft.com/windowsdesktop/sending-toast-notifications-71e230a2
but it only shows adding the AppUserModel.ID and not the ToastActivatorCLSID...
here is some of that code...
private void InstallShortcut(String shortcutPath)
{
// Find the path to the current executable
String exePath = Process.GetCurrentProcess().MainModule.FileName;
IShellLinkW newShortcut = (IShellLinkW)new CShellLink();
// Create a shortcut to the exe
ShellHelpers.ErrorHelper.VerifySucceeded(newShortcut.SetPath(exePath));
ShellHelpers.ErrorHelper.VerifySucceeded(newShortcut.SetArguments(""));
// Open the shortcut property store, set the AppUserModelId property
IPropertyStore newShortcutProperties = (IPropertyStore)newShortcut;
using (PropVariant appId = new PropVariant(APP_ID))
{
ShellHelpers.ErrorHelper.VerifySucceeded(newShortcutProperties.SetValue(System Properties.System.AppUserModel.ID, appId));
ShellHelpers.ErrorHelper.VerifySucceeded(newShortcutProperties.Commit());
}
// Commit the shortcut to disk
IPersistFile newShortcutSave = (IPersistFile)newShortcut;
ShellHelpers.ErrorHelper.VerifySucceeded(newShortcutSave.Save(shortcutPath, true));
}
the thing is that the AppUserModel does not have a ToastActivatorCLSID property. seems strange.
i figured i could just add another using block to add the ToastActivatorCLSID property like this
using (PropVariant clsId = new PropVariant(CLSID))
{
ShellHelpers.ErrorHelper.VerifySucceeded(newShortcutProperties.SetValue(System Properties.System.AppUserModel.ToastActivatorCLSID, CLSID));
ShellHelpers.ErrorHelper.VerifySucceeded(newShortcutProperties.Commit());
}
but the SystemProperties.System.AppUserModel.ToastActivatorCLSID doesnt exist.
right now the appuser model is coming from Microsoft.WindowsAPICodePack.Shell.PropertySystem.
this page shows it should exist
https://learn.microsoft.com/en-us/windows/desktop/properties/props-system-appusermodel-toastactivatorclsid
i would if with that information i could make some kind of interface or something to add in that ToastActivatorCLSID.
there is very little on the internet on this topic. Don't know if there is a different reference or something.
any help would be great

I've been running into the same problem and I've found a work around.
Clone this github repo: https://github.com/aybe/Windows-API-Code-Pack-1.1
open the WindowsAPICodePack12.sln in visual studio.
open Shell > PropertySystem > SystemProperties.cs
find the AppUserModel class on line 2302
add this code to the class:
public static PropertyKey ToastActivatorCLSID
{
get
{
PropertyKey key = new PropertyKey(new Guid("{9F4C2855-9F79-4B39-A8D0-E1D42DE1D5F3}"), 26);
return key;
}
}
Build the project. Open the bin folder (where the built projects go) and find Microsoft.WindowsAPICodePack.dll and Microsoft.WindowsAPICodePack.Shell.dll
Reference these dlls in your project instead of the original code pack.

C# Puma.Net The library dibapi.dll could not be found

I've got some issues running Puma.Net. I've got all the functions looking fine in the code but when it comes this point:
Value = pumaPage.RecognizeToString();
It then gives an error saying the library dibapi.dll can't be found. But I just can't even add it as a reference it says something like
Can't add reference Make sure the file is accessible and that it is a assembly or Com-Component.
So I gave it all the rights it needs to be read, write & executed. I even gave it full controll on all the users but it just won't work.
Maybe I made a mistake somewhere so here is the full code of the programm.
static void Main()
{
string Image = "V:/Test_images/value.PNG";
Console.WriteLine("Running the Program!");
var pumaPage = new PumaPage(Image);
string Value;
using (pumaPage)
{
pumaPage.FileFormat = PumaFileFormat.RtfAnsi;
pumaPage.EnableSpeller = false;
pumaPage.Language = PumaLanguage.Digits;
Value = pumaPage.RecognizeToString();
}
Console.WriteLine("The Value is" + Value);
Console.ReadLine();
}
I've added the Puma.Net dll and "using Puma.Net;" so it should work. Does someone got any idea what could be wrong?
Here is also the errormessage that appears all the time.
The Error Message which appears
If you need a translation just tell me.
Btw it is a Console Application and I would love to keep it that way. If it is not possible then I can also try to use turn it into a Form Application but that's a whole new part for me so it could take a while to get into it.

You need to copy dibapi.dll to the output folder as described in the documentation:
Steps to add Puma.NET to your project:
1. Add reference to Puma.Net.dll;
2. Make sure that after project building the output folder (i.e. bin\Debug or bin\Release)
contains files Puma.Net.dll and puma.interop.dll. If the last is not present (IDE didn’t
copy it) copy it to the folder manually;
3. Copy dibapi.dll to the output folder;

Microsoft Visual Linking Forms/Projects

So I have one Solution with four Projects in it. In Project_Owner_Add I want a Next button so that when it is clicked one of the other Projects is displayed.
This is my code.
private void buttonNext_Click(object sender, EventArgs e)
{
Project_Owner_Add.Form1 next = Project_Owner_Add_Product_Owner.Form1();
next.Show();
}
The error message is as follows:
Project_Owner_Add_Product_Owner does not exist in the current context
I'm assuming I'm going about calling information from a separate Project all wrong but I had sort of thought it was a matter of simply linking the forms together (this also doesn't work).
Any suggestions on how to get around this?

Add reference to your other project as already suggested, also you can use using directive to set some alias for your Form1 class in case when it exists in both projects.
The keyword new is essential when it comes to instantiating classes in C#. You can do something like this :
Add reference to other project if needed - > then :
using MyForm = Project_Owner_Add.Form1;
private void buttonNext_Click(object sender, EventArgs e)
{
MyForm next = new MyForm();
next.Show();
}

You need to add a reference to the second project. Do the following steps:
Right click Project_Owner_Add and select Add Reference.
Then Solution --> Projects and select second project from the list.
Then try this:
secondprojectNamespace.Form1 next = new secondprojectNamespace.Form1();
next.Show();

InternetExplorer being set up as __ComObject instead of SHDocVw.InternetExplorer

I'm having a problem with the InternetExplorer in SHDocVw.dll. I also have mshtml.tlb referenced (while googling, I did read 1 comment that said I should have mshtml.dll referenced, but that this couldn't be done in Microsoft Visual Studio Express, I don't know how true this is though). Here's one small function in its most basic form that won't work for me:
public static HtmlElement GetDocumentControlByID(
ref SHDocVw.InternetExplorer IEObj,
string ControlID)
{
HtmlElement ReturnElement = IEObj.Document.GetElementById(ControlID);
return ReturnElement;
}
The problem is that when I create the IEObj instance, it is considered type System.__ComObject instead of SHDocVw.InternetExplorer, and all subparts are also of type System.__ComObject. When I try any of the following statements...
Document WebDoc = IEObj.Document;
HtmlElement ReturnElement = IEObj.Document.GetElementById(ControlID);
...I keep getting the same error message:
Cannot implicitly convert type 'System.__ComObject' to 'System.Windows.Forms.HtmlElement'
(obviously the convert-to type is different for the IEObj.Document).
I am new to c# (coming from VBA, so I am familiar with programming), but in VBA, the equivelant works perfectly without needing to convert it in any way.
Is it something I'm doing wrong? In case it's my creation of the object, the following is (roughly) the code I used to test the function:
public static void Main(String [] args)
{
SHDocVw.InternetExplorer IEObj = new SHDocVw.InternetExplorer();
IEObj.Navigate("http://sports.ladbrokes.com/");
while (IEObj.ReadyState != 4)
{
}
// There is a textbox that definitely exists
HtmlElement NetControl = GetDocumentControlByID(ref IEObj, "username");
// I was goint to manipulate it after this, but it crashes in the above function.
}
All I really want to do is latch onto various elements so that I can enter text into textboxes, click buttons etc. I would also need to be able to use the Document variables as well (like Document.Body.InnerHtml, etc). The whole project is to be a bunch of functions to be contained in a DLL to be referenced by other projects.

You're trying to use the WinForms HtmlElement class, which isn't a COM object.
You can't mix the native InternetExplorer COM object with the managed classes in WinForms.
You should use the WinForms classes (the WebBrowser control) instead.
In most cases, you don't need COM at all.

Silverlight C# - ComponentOne Spellchecker not loading dictionary

This may be a long shot, but I'm using ComponentOne's Spellchecker control for Silverlight. I made a test project, added a plain textbox and a button to it, added the references to the C1.Silverlight and C1.Silverlight.SpellChecker bits, and added the dictionary file to my project.
In the code, I called up the spellchecker on button1's click event and it worked SPLENDIDLY. The spellchecker dialog shows up, and works exactly as it should.
Since that test was successful, I then tried to implement this into my existing project. I've had no success for absolutely NO reason that I can determine, since I used the EXACT SAME code.
Here's the code I use to call the component:
using C1.Silverlight;
using C1.Silverlight.SpellChecker;
using C1.Silverlight.Resources;
public partial class MainPage : UserControl
{
C1SpellChecker spellChecker = new C1SpellChecker();
public MainPage()
{
InitializeComponent();
spellChecker.MainDictionary.LoadAsync("C1Spell_en-US.dct");
}
private void btnSpelling_Click(object sender, RoutedEventArgs e)
{
var dlg = new C1SpellDialog();
spellChecker.CheckControlAsync(txtArticle, false, dlg);
}
The references to C1.Silverlight and C1.Silverlight.Spellchecker are added to this project as well, and the dictionary as been added in the same fashion as well. The issue seems to be that for whatever reason the dictionary is not loading, because the spellChecker.Enabled method returns whether or not the main dictionary has been loaded. If I call MessageBox.Show("SpellChecker Enabled = " + spellChecker.Enabled.ToString()); it shows false, even though the call to load the dictionary is there (as you can see).
What would cause the dictionary to not load? Have I added it to my project incorrectly somehow?
EDIT: I suspect that I have added the dictionary to the project incorrectly, because the ComponentOne reference states:
If C1SpellChecker cannot find the
spelling dictionary, it will not throw
any exceptions. The Enabled property
will be set to false and the component
will not be able to spell-check any
text.
I just don't know what's wrong though because it was added in the same way that it was in the test project (Right clicked on the project.web->Add->Existing Item)
As always, thank you!

You could add the dictionary to the Silverlight app as an embedded resource and then load it using this code:
public MainPage()
{
InitializeComponent();
// load C1SpellChecker dictionary from embedded resource
var asm = this.GetType().Assembly;
foreach (var res in asm.GetManifestResourceNames())
{
if (res.EndsWith(".dct"))
{
using (var s = asm.GetManifestResourceStream(res))
{
sc.MainDictionary.Load(s);
break;
}
}
}
}

I think this post is duplicated in our forum as well, but will answer first here. Please try this:
1) Try to access the .dct file using your browser. If you cannot see it, it's probably because your web server is not serving that type of files. You need ton configure the web server to allow it.
2) verify the URL you are using is correct.http://helpcentral.componentone.com/CS/silverlight_161/f/78/p/86955/241328.aspx#241328
3) Check you are setting everything correctly: http://helpcentral.componentone.com/CS/silverlight_161/f/78/p/81924/227790.aspx#227790
Hope this helps!
