I'm making a c# windows application that will make it possible to fully control your windows computer via a gaming controller only. Right now I'm done with mouse control coding and I'm testing for bugs. What I want next is to create a virtual keyboard which shows up when a text box in any application is clicked. For example, the android keyboard which only appears when you need it. I have searched and the only thing I have found so far is how to call a function only when the text box is in the same Form. My question is if there is a way to make a listener when a textbox is clicked for all open programs. I would appreciate any help.
You should send the code or integer between forms when user click on the textbox using code like :
public string _label3
{
get { return label3.Text; }
}
you write value and send it to other form then receive it using set method.
public string _label3
{
set { return label1.Text; }
}
Using timer to watch coming value all time or check for label1.text then, when u receive this value
using this code to open virtual Keyboard.
System.Diagnostics.Process.Start("osk.exe");

We have a Xamarin app (Android) that at one stage opens up a web view (Webkit.Webview not Forms.Webview). This directs the user to a page on a third party site which has been set up for us.
Firstly - on certain input fields the keyboard which shows up is the wrong one - we are expecting a dismissable keyboard (i.e. "Done" in the bottom corner, not a "Submit"). I know this can be changed but not sure what is the correct way to do this. Does it have to be the metadata/text inputs on the web page that is changed? If so - what needs to be modified per text box entry on the html of the page? Just the type? i.e:
<input type="email">
Secondly, rather than wait for the third party to fix the page, is there a way we can force the webview to always open a certain keyboard type?
We have an option of intercepting the keyboard key presses and trying to dismiss the keyboard on return press at the minute. But would prefer not to put a hack in that intercepts every key press.
Appreciate the help, not sure what the way forward is here.
Thanks
From the comments: To your second question about forcing a keyboard button, you can check out this link which describes how to override OnCreateInputConnection to specify the Keyboard Enter Button type.
public class MyWebView : WebView {
...
public override IInputConnection OnCreateInputConnection (EditorInfo outAttrs) {
var inputConnection = base.OnCreateInputConnection (outAttrs);
// outAttrs.ImeOptions in Xamarin only allows ImeFlags but it also should allow ImeActions
outAttrs.ImeOptions = outAttrs.ImeOptions | (ImeFlags)ImeAction.Next;
return inputConnection;
}
}
That will not dismiss your keyboard when tapped though since it is meant to take the user to the next input. Hopefully someone else can come along and either provide a better answer or give a good way to dismiss the keyboard in this situation without hacking something together.
Good evening folks,
I'm building a simple application (A) that sends Strings to a textbox of another application (B). I was able to this step, but afterwards I'd like to automatically press a button placed just under the textbox. The problem is that I can't get the Handle of the Button; using "Window Detective"(similiar to Spy++), I see only the textboxes (called "TEdit", see the attachments) and no Buttons!. I'd like to add also that there's no only a Button but 3!! So, how could I press a specific Button? Is there another chance to get the Handle?

Based on the class name TEdit that's a VCL application probably coded in Delphi. The buttons are likely TSpeedButton and non-windowed. You won't be able to send them messages and they are not automatable.
Faced with this your best hope of success is to fake input. Fake the mouse click at the appropriate location on the form. It's not pretty but there's little option.
I need to show, and input some text in xbox-like onscreen keyboard. Sadly, when I call Guide.BeginShowKeyboardInput, there is only some funny textbox shown, and i must fill it via keyboard. I know, that on PC iv very normal to use keyboard, but in my case i MUST enter text via gamepad, using xbox on screen keyboard.
Is there any way to achieve this? To call xbox onscreen keyboard on PC?
If you need one for like a touchscreen monitor you could do
using System.Diagnostics;
using System.IO;
then use this function
Process.Start(Environment.GetFolderPath(Environment.SpecialFolder.System) + Path.DirectorySeparatorChar + "osk.exe");
but if you need it to work with like an xbox controller you will probably need to build your own
No. It was a design decision (documented here) to give the end user control of the keyboard being invoked. Therefore, the end user has to touch a text box (or the like) to invoke the virtual on-screen keyboard.
Check this text form this link
Blockquote User-driven invocation
The invocation model of the touch keyboard is designed to put the user in control of the keyboard. Users indicate to the system that they want to input text by tapping on an input control instead of having an application make that decision on their behalf. This reduces to zero the scenarios where the keyboard is invoked unexpectedly, which can be a painful source of UI churn because the keyboard can consume up to 50% of the screen and mar the application's user experience. To enable user-driven invocation, we track the coordinates of the last touch event and compare them to the location of the bounding rectangle of the element that currently has focus. If the point is contained within the bounding rectangle, the touch keyboard is invoked.
Blockquote This means that applications cannot programmatically invoke the touch keyboard via manipulation of focus. Big culprits here in the past have been webpages—many of them set focus by default into an input field but have many other experiences available on their page for the user to enjoy. A good example of this is msn.com. The website has a lot of content for consumption, but happens to have a Bing search bar on the top of its page that takes focus by default. If the keyboard were automatically invoked, all of the articles located below that search bar would be occluded by default, thus ruining the website's experience on tablets. There are certain scenarios where it doesn't feel great to have to tap to get the keyboard, such as when a user has started a new email message or has opened the Search pane. However, we feel that requiring the user to tap the input field is an acceptable compromise.

You might find your answer in here, It has all information about the input of a gamepad and such.
There is a good guide on how to do this here:
static public string GetKeyboardInput()
{
if (HandleInput.currentState.IsButtonDown(Buttons.B))
{
useKeyboardResult = false;
}
if (KeyboardResult == null && !Guide.IsVisible)
{
string title = "Name";
string description = "Pick a name for this game";
string defaultText = "Your name here";
pauseType = PauseType.pauseAll;
KeyboardResult = Guide.BeginShowKeyboardInput(HandleInput.playerIndex, title,
description, defaultText, null, null);
useKeyboardResult = true;
pauseType = PauseType.pauseAll;
}
else if (KeyboardResult != null && KeyboardResult.IsCompleted)
{
pauseType = PauseType.none;
KeyboardInputRquested = false;
string input = Guide.EndShowKeyboardInput(KeyboardResult);
KeyboardResult = null;
if (useKeyboardResult)
{
return input;
}
}
return null;
}
And your Update method should contain something like this:
if (KeyboardInputRequested)
{
string result = GetKeyboardInput();
}
if (result != null)
{
//use result here
}
It is unlikely that the on-screen keyboard was packaged in the XNA DLLs for PC, but if you really want to find out, you could research a free .NET decompiling program (such as ILSpy) and look through it.
Also, you can't use the chatpad either. I would recommend either making your own on-screen keyboard that is usable by a controller, or maybe, if you can, using the MonoGame framework (an open-source version of XNA), and modifying it to have an on-screen keyboard on Windows.
You could also make a separate program that acts as a virtual keyboard controlled by the controller.
I'm tired and hungry, so I might of missed it, but from what I can see no existing post covers this...
I'm writing a plugin for an application. My plugin loads a form to get some data specifically, it uses the webcam to scan for a barcode. Once it's found a barcode, the form hides itself (incase it's needed again later). This is how I currently call the form that does the barcode work:
string readData = null;
if (eye == null)
{
System.Windows.Forms.Application.EnableVisualStyles();
eye = new CamView();
}
eye.Show();
if (eye.found)
{
readData = eye.readData;
}
return readData;
So, my problem is that eye.show() doesn't block. It makes the form appear and carries right on before there's a chance for the barcode to appear. I imagine I need to use some form of threading or locking, but my crude attempts to do so have just frozen the interface completely.
The "eye" form is basically just a viewfinder for the webcam, and relies on the camera_OnImageCapture event to make it do it's image checks for the barcode.
Is there an elegant way to make the application calling the plugin wait for the form to finish? Or do I just need to add an accept button to the "eye form?"
Cheers. And humble apologies if this is in anyway a repost.

"You can use this method to display a modal dialog box in your application. When this method is called, the code following it is not executed until after the dialog box is closed."
You are on the right track. You change the code to show CamView as a modal dialog but do no add an Accept button. Instead change camera_OnImageCapture to close the dialog.
I'm coding a simple text editor using Windows Forms. As in many editors, when the text changes the title bar displays an asterisk next to the title, showing that there is unsaved work. When the user saves, this goes away.
However, there is a problem. This is handled in the change event of the main text box. But this gets called too when a file is opened or the user selects "New file", so that if you open the editor and then open a file, the program says that there are unsaved changes. What is a possible solution?
I thought of having a global variable that says whether the text changed in a way that shouldn't trigger the asterisk, but there has to be a better way.
before loading data to a textbox, unassociate first the eventhandler for change
uxName.TextChanged -= uxName_TextChanged;
uxName.Text = File.ReadAllText("something.txt");
uxName.TextChanged += uxName_TextChanged;
This is a horrible solution, but every time the text change event fires, compare the value of the textbox to some variable, and if they are different store the contents on the textbox in a variable and add the asterisk. When the method is invoked via the New File dialog or any other such event that is NOT changing the text, the asterisk won't appear.
This is not a viable solution for a real text editor since the memory would quickly get out of hand on even medium-sized files. Using a finger tree or whatever data structure text editors use to compare "versions" of the text is the only real efficient solution, but the premise is the same.
http://scienceblogs.com/goodmath/2009/05/finally_finger_trees.php
Below the second picture he mentions the use of finger trees in text editors to implement an extremely cheap "undo" feature, but I'm sure you can see the validity of the tree for your problem as well.
There are no global variables in C#. You should have such an variable as an instance variable in your form (or better yet, in a model for which your form is a view), and that is perfectly fine.
This is a very simple and stupid solution. I would use a MVP design pattern for this but here the fastest and simple solution:
//Declare a flag to block the processing of your event
private bool isEventBlocked = false;
private void OnTextChanged(object sender, EventArgs e)
{
if(!isEventBlocked)
{
//do your stuff
}
}
private void OnNewFile() //OR OnOpenFile()
{
try
{
isEventBlocked = true;
CreateFile();
}
catch
{
//manage exception
}
finally
{
isEventBlocked = false;
}
}
