There is a post in here about that ...but it doesn't work for me. I have added a system.speech.dll that I found in the internet but i cannot use System.speech , because it doesn't appear.
Error 1 The type or namespace name 'SpeechRecognizer' could not be found (are you missing a using directive or an assembly reference?)
Error 2 The type or namespace name 'SpeechRecognizedEventArgs' could not be found (are you missing a using directive or an assembly reference?)
I have used this code. I am using Windows Vista 64
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using SpeechLib;
using System.Threading;
namespace WindowsFormsApplication13
{
public partial class Form1 : Form
{
SpeechRecognizer rec = new SpeechRecognizer();
public Form1()
{
InitializeComponent();
rec.SpeechRecognized += rec_SpeechRecognized;
}
void rec_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
lblLetter.Text = e.Result.Text;
}
private void Form1_Load(object sender, EventArgs e)
{
var c = new Choices();
// Doens't work must use English words to add to Choices and
// populate grammar.
//
//for (var i = 0; i <= 100; i++)
// c.Add(i.ToString());
c.Add("one");
c.Add("two");
c.Add("three");
c.Add("four");
c.Add("Five");
c.Add("six");
c.Add("seven");
c.Add("eight");
c.Add("nine");
c.Add("ten");
// etc...
var gb = new GrammarBuilder(c);
var g = new Grammar(gb);
rec.LoadGrammar(g);
rec.Enabled = true;
}
}
}
I agree with James Ogden. Also, you should add a "using" statement:
using System.Speech.Recognition
Or, fully qualify your class names.
1) You need to add a reference to System.Speech in your project
2) You shouldn't have had to find 'System.Speech.dll' on the Internet, it should be in .Net 3 (or 3.5, but get 3.5 anyway unless you've a compelling reason not to)
Edit:
You might want to look here:
http://dotnet.org.za/beta/archive/2008/01/06/system-speech-recognition.aspx
Check that you have a language engine matching the language you have configured in Vista. See http://support.microsoft.com/kb/934377
While not directly applicable to the above question - it is worth noting that the Speech SDK will not nessecarily be availible on each clients machines. While Vista includes a speech recognizer, XP does not. A possible way to correct this is to get the XP users to install the Speech SDK, which includes one. The other is to add Office 2003 (not 2007) as a dependency.
Im having problem about SpeechRecognizer class on Windows XP. sometimes it works but sometimes it doesnot work, and need to restart pc. on windows 7 its working fine. I think its some problem in speech engine itself, cause when I run my application several times it stops working.
Im using this code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using SpeechLib;
using System.Threading;
namespace WindowsFormsApplication13
{
public partial class Form1 : Form
{
SpeechRecognizer rec = new SpeechRecognizer();
public Form1()
{
InitializeComponent();
rec.SpeechRecognized += rec_SpeechRecognized;
}
void rec_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
lblLetter.Text = e.Result.Text;
}
private void Form1_Load(object sender, EventArgs e)
{
var c = new Choices();
c.Add("one");
c.Add("two");
c.Add("three");
c.Add("four");
c.Add("Five");
c.Add("six");
c.Add("seven");
c.Add("eight");
c.Add("nine");
c.Add("ten");
// etc...
var gb = new GrammarBuilder(c);
var g = new Grammar(gb);
rec.LoadGrammar(g);
rec.Enabled = true;
}
}
}

I am trying to pass a string my function in Windows Form Application in order to invoke InteropAssembly.dll from a LabVIEW script. The script takes a string for opening image and do some process and then return 2 different images. But I am getting the error The type 'LVBaseRefnum' is defined in an assembly that is not referenced. You must add a reference to assembly 'NationalInstruments.LabVIEW.RefnumTypes'. I have checked the forum and so and found this . But it was posted quite long time ago and still no valid answer. Have you ever encounter this error any solution? Thanks in advance and my code as follows:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using InteropAssembly;
namespace testLabview
{
public partial class Form1 : Form
{
private object img1;
private object img2;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
this.pictureBox1 = null;
this.pictureBox2 = null;
string text = this.textBox1.ToString();
LabVIEWExports.test(text, out Image img1, out Image img2);
this.pictureBox1.Image = img1;
this.pictureBox2.Image = img2;
}
}
}
the code is working perfectly but after publishing it just doesn't open.
I created a page to test graphics, however as the webbrowser C# does not work, as it starts in IE I tried to use Cefsharp but it is not going either,the error that appears to me is Cefsharp.Core.Runtime.dll, the version I am using of cefsharp is 94.4.11. but the problem is that when I use it by Visual Studio 2022 it works but when I do the compilation and I publish it to generate the executable it doesn't just give an error or it doesn't even open

I read this answer and tried playing a single note with NAudio.Midi:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using NAudio.Midi;
using System.Threading;
namespace SoundVision10
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
//Thread.Sleep inside GUI is just for example
using (MidiOut midiOut = new MidiOut(0))
{
midiOut.Volume = 65535;
midiOut.Send(MidiMessage.StartNote(60, 127, 0).RawData);
MessageBox.Show("Sent");
Thread.Sleep(1000);
midiOut.Send(MidiMessage.StopNote(60, 0, 0).RawData);
Thread.Sleep(1000);
}
}
}
}
It displays "Sent" and nothing else happens.
Sound is turned on.
The name of the first Midi output device is "Microsoft Gs Wavetable Synth"
Did I forget something?
Change the channel number to 1 and it works.
midiOut.Send(MidiMessage.StartNote(60, 127, 1).RawData);
I replaced NAudio.dll 1.7.3.0 with NAudio.dll 1.3.8.0 and it fixed the issue.
I was using the .Net WebBrowser object but don't like the messy way the compatibility mode works. So I switched to CEFSharp object.
However, the object doesn't display in my form. I looked at the Example Winform project with CEFSharp but it doesn't seem to display it in a winform but runs it as a separate application which isn't want i want.
I figure I am missing some obvious method or property that must be set initially. In the code below I have what I am using for CEFSharp and you will see two lines commented out which is what I was using for .Net WebBrowser that worked.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using CefSharp.WinForms;
namespace GoogleSiren
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
ChromiumWebBrowser myBrowser = new ChromiumWebBrowser("http://wwww.cnn.com");
//WebBrowser myBrowser = new WebBrowser();
//myBrowser.Navigate("http://www.cnn.com");
myBrowser.Location = new Point(200, 200);
myBrowser.Size = new Size(500, 300);
this.Controls.Add(myBrowser);
}
}
}
Try setting the Size and Location as part of the constructor:
ChromiumWebBrowser myBrowser = new ChromiumWebBrowser("http://wwww.cnn.com")
{
Location = new Point(200, 200),
Size = new Size(500, 300)
};
this.Controls.Add(myBrowser);
My code was missing Cef.Initialize() call. Once I added that it worked fine.
I am trying to call javascript using OpenWebKitSharp from WinForms with .NET 4
Here is the code I am trying to use.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using WebKit;
using WebKit.Interop;
using WebKit.JSCore;
using webkitForm.Properties;
namespace webkitForm
{
public partial class Form1 : Form
{
WebKitBrowser webKitSharpBrowser = new WebKitBrowser();
public Form1()
{
InitializeComponent();
this.Controls.Add(webKitSharpBrowser);
webKitSharpBrowser.Width = 600;
webKitSharpBrowser.Height = 400;
}
private void button1_Click(object sender, EventArgs e)
{
webKitSharpBrowser.Preferences.AllowPlugins = true;
webKitSharpBrowser.UseJavaScript = true;
webKitSharpBrowser.Navigate("http://sandbox.icontact.com");
webKitSharpBrowser.GetScriptManager.EvaluateScript("alert('An alert from C#!');"); //Call javascript?
}
}
}
I can't get javascript to fire for anything... there must be something that I am missing.
Thanks in advance.
Well, it seems like it can't be done the way you want to:
if you are using .NET 4, calling a function is possible by using:
<webkitbrowser>.GetScriptManager.CallFunction("name", new Object[] { arg1, arg2, ...});
If you want to use .NET 2 you can use:
<webkitbrowser>.StringByEvaluatingJavaScriptFromString("name(arguments)")
- Open Webkit Sharp Issues
I tested your code, it IS working, but calling the alert function only triggers an event (WebKitBrowser.ShowJavaScriptAlertPanel), you are responsible for handling that event and showing a message or updating a label, or anything else.
For example:
Browser.ShowJavaScriptAlertPanel += Browser_ShowJavaScriptAlertPanel;
and then handle the event:
private void Browser_ShowJavaScriptAlertPanel(object sender, WebKit.ShowJavaScriptAlertPanelEventArgs e)
{
MessageBox.Show(e.Message);
}
