I wrote a simple wpf application which handles a TCPIP and a Serial communication. At the first version of the App I used a "GUI" with a connect button and so on. This version was running on the Tablet. The Tablet is a ThinkPad with Windows 8.
The second version the app should run without any GUI, but with an taskbar icon. I was able to create the taskbar icon and so. The app perfectly works on my computer. Its possible to install the app on the tablet, but it just doesn't run.
Has anybody a clue why the app doesn't open?
Beneath you can find some source code, how I created the icon and so on. In the Visual Studio project I disabled the "Main Window" which looks like this
xml-code
Title="MainWindow" Height="350" Width="525" Visibility="Hidden">
c# - code
public MainWindow()
{
InitializeComponent();
// Initailize Menu
this.components = new System.ComponentModel.Container();
this.contextMenu1 = new System.Windows.Forms.ContextMenu();
this.menuItem1 = new System.Windows.Forms.MenuItem();
this.menuItem2 = new System.Windows.Forms.MenuItem();
this.menuItem3 = new System.Windows.Forms.MenuItem();
this.menuItem4 = new System.Windows.Forms.MenuItem();
// Initialize contextMenu1
this.contextMenu1.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] { this.menuItem1 });
this.contextMenu1.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] { this.menuItem2 });
this.contextMenu1.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] { this.menuItem3 });
this.contextMenu1.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] { this.menuItem4 });
// Initialize Menu Items
this.menuItem3.Index = 0;
this.menuItem3.Text = "Connect";
this.menuItem3.Click += new System.EventHandler(this.Connect);
//
this.menuItem2.Index = 1;
this.menuItem2.Text = "Disconnect";
this.menuItem2.Click += new System.EventHandler(this.Disconnect);
//
this.menuItem4.Index = 2;
this.menuItem4.Text = "About";
this.menuItem4.Click += new System.EventHandler(this.About);
//
this.menuItem1.Index = 3;
this.menuItem1.Text = "Exit";
this.menuItem1.Click += new System.EventHandler(this.Exit);
// Create the NotifyIcon.
this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);
// The Icon property sets the icon that will appear
// in the systray for this application.
notifyIcon1.Icon = new Icon("icon.ico");
// The ContextMenu property sets the menu that will
// appear when the systray icon is right clicked.
notifyIcon1.ContextMenu = this.contextMenu1;
// The Text property sets the text that will be displayed,
// in a tooltip, when the mouse hovers over the systray icon.
notifyIcon1.Text = "Icon Test";
notifyIcon1.Visible = true;
//Handle the Click event
notifyIcon1.MouseUp += new MouseEventHandler(ShowContextMenu);
}
EDIT
is it possible that System.Windows.Input using directive is needed that the app starts on the tablet? I had to exclude that one because of a collision with another using directive..
There is another issue. I believe its an Windows 8 error. The app is working on my Win7 machine, but neither on a Win8 notebook nor a Win8 tablet.

I want to open a WPF ContextMenu when the user clicks the system tray icon. With Windows Forms this is straight-forward, just call notifyIcon.ContextMenu = contextMenu and you're set.
On WPF we can not set the ContextMenu that easily because WPF's ContextMenu class is not related to Forms ContextMenu. The alternative I have been pursuing is to handle NotifyIcon's Click event to open the WPF-style ContextMenu.
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
// This is intended to be a system tray application so we hide the window
this.Visibility = Visibility.Hidden;
// Winform context menu
// The context menu closes when the user clicks anywhere outside the menu
// The user can navigate the menu with the keyboard arrows and close with ESC
var notifyIcon1 = new System.Windows.Forms.NotifyIcon();
var contextMenu = new System.Windows.Forms.ContextMenu();
var menuItem = new System.Windows.Forms.MenuItem();
menuItem.Text = "WinForm Menu Item";
contextMenu.MenuItems.Add(menuItem);
notifyIcon1.ContextMenu = contextMenu;
notifyIcon1.Icon = Properties.Resources.ico;
notifyIcon1.Visible = true;
// WPF context menu
// The user cannot close the menu by clicking outside its bounds
// Does not detect any keyboard input
var notifyIcon2 = new System.Windows.Forms.NotifyIcon();
notifyIcon2.Icon = Properties.Resources.ico;
notifyIcon2.Visible = true;
notifyIcon2.Click += NotifyIcon2_Click;
}
private void NotifyIcon2_Click(object sender, EventArgs e)
{
var contextMenu = new ContextMenu();
var menuItem = new MenuItem();
menuItem.Header = "WPF Menu Item";
contextMenu.Items.Add(menuItem);
contextMenu.IsOpen = true;
}
}
The issue with this approach is that the WPF ContextMenu never gets any hint that the user has navigated away from the menu and should close (Eg, when the user clicks outside the bounds of the menu). None of the Focus or MouseCapture events are ever triggered and I am unable to close the menu other than by clicking on one of its items.
So the question here, to put slightly different, is: how do I properly emulate the NotifyIcon's ContextMenu closing behavior using WPF's ContextMenu?
I faced similar issue. You can try if you want
notifyIcon1.ContextMenuStrip = new Forms.ContextMenuStrip();
notifyIcon1.ContextMenuStrip.Items.Add("YourMenuItem",null, MenuItemEvent);
I hope this will solve the problem.
I want to display custom text or control on the Windows 10 Lockscreen, when I click on a button. I tried it with an UWP Application.
My goal is something like this:
And the Code I tried:
ToastContent content = new ToastContent()
{
//Duration = ToastDuration.Long,
Scenario = ToastScenario.Reminder,
Visual = new ToastVisual()
{
BindingGeneric = new ToastBindingGeneric()
{
Attribution = new ToastGenericAttributionText()
{
Text = "Hello World"
}
}
},
Actions = new ToastActionsCustom()
{
Buttons = {
new ToastButton ("mycontent", "myargs")
}
}
};
var notification = new ToastNotification(content.GetXml());
ToastNotificationManager.CreateToastNotifier().Show(notification);
Also I saw this post and tried it of course, but it wasnt helpfull: Windows Lock Screen display text programmatically C#
Maybe you could help me to achive my goald
I thank you in advance
The screenshot you post above is smtc that used to show current playing music, for enable it you need to enable the app Background Media Playback, but it only use to show the media info, it can't use to share custom info like you mentioned scenario.
For your scenario, the better way is register your app LockScreen capability like the following.
<Applications>
<Application Id="App"
Executable="$targetnametoken$.exe"
EntryPoint="xxxxx.UWP.App">
.......
<uap:LockScreen BadgeLogo="Assets\BadgeLogo.png" Notification="badgeAndTileText"/>
</uap:VisualElements>
</Application>
</Applications>
And set the app as main toast in the lock screen Setting page -> Personalization -> lock screen -> Choose one app to show detailed status on the lock screen If you have resisted the app, it will show in the apps list.
Code Sample
private void Button_Click(object sender, RoutedEventArgs e)
{
TileContent content = new TileContent()
{
Visual = new TileVisual()
{
LockDetailedStatus1 = "Hello world",
TileWide = new TileBinding() { }
}
};
var notification = new TileNotification(content.GetXml());
TileUpdateManager.CreateTileUpdaterForApplication().Update(notification);
}
I am trying to develop a gtk application on mac using gtk#. I created a tree view just like in the tutorial but the arrows are not rendering properly as seem below, there are no arrows. I can click to open and close but the actual arrows aren't working.
I copy pasted the code from the tutorial and It did the same thing, but here is my code anywhere. I have also verified view.ShowExpanders is set to true
Application.Init();
Window window = new Window("Editor Window");
window.SetPosition(WindowPosition.Center);
window.HeightRequest = 800;
window.WidthRequest = 1200;
TreeView view = new TreeView();
view.WidthRequest = 500;
TreeViewColumn column = new TreeViewColumn();
column.Title = "Heirarchy";
CellRendererText cell = new CellRendererText();
column.PackStart(cell, true);
view.AppendColumn(column);
column.AddAttribute(cell, "text", 0);
TreeStore store = new TreeStore(typeof(string));
TreeIter i = store.AppendValues("Project");
i = store.AppendValues(i,"Room1");
i = store.AppendValues(i, "Item");
store.AppendValues(i, "Attribute");
store.AppendValues(i, "Attribute");
store.AppendValues(i, "Attribute");
view.ShowExpanders = true;
view.Model = store;
view.ShowExpanders = true;
window.Add(view);
window.DeleteEvent += ExitWindow;
window.ShowAll();
Application.Run();
Is there some sort of image asset that doesn't exist on my computer? How would I install that on mac? Thank you for any help you can provide.
As a comment suggested, using brew install adwaita-icon-theme fixed the problem
Is there an official way or trick to open the Windows Phone ApplicationBar using C# from the code-behind? I'd like to show my users additional options hidden in the menu.
To be clear, I don't need to create the menu in code-behind (but can, if that helps in any way).
There are no way to open application bar programmatically. But you can create application bar in C#. Here is the sample.
ApplicationBar = new ApplicationBar();
ApplicationBar.Mode = ApplicationBarMode.Default;
ApplicationBar.Opacity = 1.0;
ApplicationBar.IsVisible = true;
ApplicationBar.IsMenuEnabled = true;
ApplicationBarIconButton button1 = new ApplicationBarIconButton();
button1.IconUri = new Uri("/Images/YourImage.png", UriKind.Relative);
button1.Text = "button 1";
ApplicationBar.Buttons.Add(button1);
ApplicationBarMenuItem menuItem1 = new ApplicationBarMenuItem();
menuItem1.Text = "menu item 1";
ApplicationBar.MenuItems.Add(menuItem1);
I have a program that has some buttons, one of them is used to switch "Themes".
There are two themes, one is the normal Windows theme and the other is called Style2.
This is how I tried the switching
private bool UsingWindowsStyle = true;
private ResourceDictionary Style2= new ResourceDictionary() { Source = new Uri("/...;component/Resources/DefaultStyles.xaml", UriKind.RelativeOrAbsolute) };
private void SwitchButton_Click(object sender, RoutedEventArgs e)
{
if (UsingWindowsStyle)
{
Resources.MergedDictionaries.Add(Style2);
UsingWindowsStyle = false;
}
else
{
Resources.MergedDictionaries.Remove(Style2);
UsingWindowsStyle = true;
}
}
My problem is, when I use this program, and press this Button, this is what happens:
Window Opened Program operating normally with Windows theme.
SwitchButton First Click Program changes visuals to the Style2 theme. All the program's buttons operating normally.
SwitchButton Second Click Program reverts back to Windows theme, but all the buttons in the program seize to work.
Points to Consider
The program does not throw any exceptions at this point.
Debugging the code, it seems that after the second click, the program does not enter the SwitchButton_Click method.
I tried readding the Click EventHandler but with no use.
SwitchButton.Click += new RoutedEventHandler(SwitchButton_Click);
Thanks in advance for your help.
I would suggest that you are trying too hard. All you need to do is to change the Style on the Window itself. Leave the dictionaries alone. :-)
Here is an example that changes a windows style when you click from the list of available styles.
My command boils down to
//Here I am changing the style on the window
NewWindow.Style = ((StyleDetailsViewModel)x).Style;
NewWindow.Show();
with various input data
public StylingViewModel(Func<string, Style> findStyle)
{
Styles = new StyleDetailsViewModel[]
{
new StyleDetailsViewModel
{
Name = "None",
Description = "Completely remove all styling and show the raw NavigationWindow including default navigation elements",
WindowStyleNone = false,
Image = "\\Resources\\WindowStyleNone.png"
},
new StyleDetailsViewModel
{
Name = "PlainWindow",
Style = findStyle("PlainWindow"),
Description = "Hides the navigation elemetns of the NavigationWindow to make it look just like a normal window",
WindowStyleNone = false,
Image = "\\Resources\\WindowStylePlain.png"
},
new StyleDetailsViewModel
{
Name = "Windows 7",
Style = findStyle("Win7NavigationWindow"),
Description = "Uses glass effects to create a window that looks almost identical to the control panel from Windows 7.",
WindowStyleNone = false,
Image = "\\Resources\\WindowStyleWin7Nav.png"
},
and
this.DataContext = new StylingViewModel(x => (Style)this.FindResource(x));
Also beware of certain Window properties that can only be set before the window opens, such as WindowStyle="None" which you need if you are doing custom chrome.
