I made my own textbox in UWP, now I want the user to add emojis from the Windows emoji-picker window.
The problem:
When I click any of the emojis with my application focused nothing happens. I check the events that could get triggered by that but non of them got. I also tried it with the ASCII-emojis, but they also don't work.
I checked the CoreWindow_CharacterReceived event and the Paste event, but neither gets fired.
The actual question:
Is there any event I can use to get the input of the emoji-picker or is there a different way?

When I click any of the emojis with my application focused nothing happens.
The problem looks your TextBox is not in focus state, you could focus textbox manually after show Emoji pikcer. Then it will input emoji correctlly.
CoreInputView.GetForCurrentView().TryShow(CoreInputViewKind.Emoji);
YourTextBox.Focus(FocusState.Programmatic);
Update
For customing textbox you could refer to official text editor code sample that implement textbox with CoreTextEditContext.

I have been attempting to fill in a few HTML input boxes from a C# form application. So far I am able to fill in the form and click buttons without issue. Triggering the form validation fields has been a whole different story. When I look at the events in the source, I see more then onfocus that is listed in code below. I was trying to avoid firing the javascript manually and I know this question has been asked, but none of the answers I see are working.I have attempted to simulate clicks, but still doesn't allow the form to be submitted and complains the input box is still empty until I click in it.
Events I see listed in browser debugger. These could be up stream and not correct, regardless I have attempted to fire them.
blur
click
focus
mouseout
mouseover
shown
code from input box that needs to be triggered.
onfocus="if (!this.tc) addLoadEvent(function() {var e = gel('sys2.incident_group'); if (!e.ac) new AJAXReferenceCompleter(gel('sys2.incident_group'), 'sys2.incident_group', '', 'true'); e.ac.onFocus();})" aria-required="true" aria-expanded="false">
var obj = webBrowser1.Document.Window.Frames[0].Document.GetElementsByTagName(tag).GetElementsByName(field);
HtmlElement ele = obj[0];
if (ele.Name == field)
{
ele.Focus();
ele.InvokeMember("blur");
ele.InvokeMember("click");
ele.InvokeMember("mousedown");
ele.InvokeMember("focus");
ele.InvokeMember("mouseout");
ele.InvokeMember("mouseover);
ele.InvokeMember("shown);
}
Update: attempted to use synchronous task and no change occurred. It almost appears lag from when the field's are being populated are keeping everything from working correctly. I can fire off one method filling in the boxes, then use a button for second and I pass the validation. When I see my submit button fire it occurs before the boxes are populated.
I have inherited an bigger C# Project from a college (hes gone so I can't ask him anymore). Im on VS2012 + .Net4.6
The first time in this Project I added a WPF Textbox to a nonmodal Window.
The problem is: I cant change the text in the TextBox.
What I found out are the following facts:
The TextBox is not readonly
I can use backspace- and delete key, no key else
contextmenu with Paste, Copy an Cut works like expected
If I open the window modal, I can change the text in the box
If I open den window nonmodal I can catch the events PreviewKeyUp, PreviewKeyDown, KeyUp and KeyDown
but I cant catch PreviewTextInput, TextInput (thats normal) and TextChanged.
When I create a WPF-Project from the scratch, everything works.
We have an own WPF-Window-Style, but it doesn't matter, if I use this style in the window or not.
Can anybody tell me whats the difference of the behavior of TextBoxes in modal / nonmodal Windows. Could you give me a tip, where I could look for a Modification of the behavior between the FromTheScratchProject and our project? Can I debug the eventhandling somehow?
Thank you a lot
It seems like your project is a mix of WinForms/Win32 and WPF.
If you instantiate your window in following way, your non-modal window will catch the keyboard events correctly:
Window wpfWindow = new Window();
ElementHost.EnableModelessKeyboardInterop(wpfWindow);
wpfWindow.Show();
I am making a game, and to open up and close the store, you press S. While in the store, you have six different choices to buy from, but they are all buttons.
However, once you buy something, the focus is no longer on the form, but on the button, and the key down event is part of the form, therefore, because the focus gets switched from the form to the button, the key down event no longer works, and disables you from closing the store and continuing on with the game.
My question is how to set the focus back to a form once a button is press? I started out with visual basic, and the code would be something along the lines of form1.setfocus, but its totally different in c#.
I have tried Activating the form, .focus, a lot, and nothing seems to be setting the focus back to the form. Help would be greatly appreciated.
Form1.focus();
But I think, to get keyboard events on Form itself, you need KeyPreview set to true for the Form so that Form gets Keys first and then other controls.
Try:
form.Focus();
MSDN:
The Focus method returns true if the control successfully received input focus. The control can have the input focus while not displaying any visual cues of having the focus. This behavior is primarily observed by the nonselectable controls listed below, or any controls derived from them.

You can add the key down event to the buttons too.
I have to detect when a combobox from an application I have not source code, has changed. The idea is to hook an event to this control, and when the event fires, get the selected value of the control. I have googled but I just have found how to hook with a window (How to hook on a window), when the header text change. I can get the handle of the control (FindWindowEx) but, I have no idea how to hook an event to the control, please guys if any can help me with this.
You can look into the SendMessage API. DDE was an old method of IPC but it still works with .net.
As a cheap easy method, just create a form with a guid + '|' + the handle of a text box as the Text property. When your app runs just load the form but don't show it (hide it from the task tray as well).
Your other app can FindWindowEx on the first apps form using the predetermined guid in the header and also get the handle to the textbox on the form (seperate it from the guid with a pipe char or something).
Now just SendMessage(WM_SETTEXT) to the textbox hwnd (give it the value the user selected in the combobox). If you put an event handler on the text_changed event it will fire in your first app.
I'm trying to make a winforms version of a program I originally wrote as a console app.
Here's a picture of my current progress. I've made the text boxes and buttons (with a read-only textbox for output). I don't know how to actually make the buttons function.
I want it to work the same as the console version did (ask for input w/ error messages for anything that isn't an positive integer, and calculate the output), but I've never done winforms before so I'm at a roadblock.
As a beginner to WinForms, you would benefit greatly from reading up on the subject. For example:
Windows-Forms-Programming-Chris-Sells (Amazon.com)
Just double click the button and it will take you to the code behind page.
You can do something as simple as add a textbox (TextBox1) add a button (Button1)
Double click button on your winform and it will take you to the click event of the button.
In the code behind type this:
TextBox1.Text = "Hello World!";
Now run your app and click the button.
