i have 2 buttons , Play and Pause , When i click pause , the music stops and when i click Play it starts the audio from beginning . I want to do it like when i press Play , it resume from where i have stopped.
private void PlayAudio()
{
McMediaElement.LoadedBehavior = MediaState.Manual;
McMediaElement.Source = new Uri("../../SingAlong/Food Fit For A King/old king cole.mp3", UriKind.RelativeOrAbsolute);
McMediaElement.Play();
}
private void button1_Click_1(object sender, RoutedEventArgs e)
{
PlayAudio();
}
private void button2_Click(object sender, RoutedEventArgs e)
{
McMediaElement.Pause();
}
Your PlayAudio() method reloads the media file when you set the Source property. This causes your object to play the newly loaded media from the beginning when you call Play(). Instead of doing this in the event handler button1_Click_1, you should call the Play() method only:
private void button1_Click_1(object sender, RoutedEventArgs e)
{
McMediaElement.Play();
}
This worked for me..
private void button1_Click_1(object sender, RoutedEventArgs e)
{
McMediaElement.LoadedBehavior = MediaState.Pause;
}
private void button2_Click_1(object sender, RoutedEventArgs e)
{
McMediaElement.LoadedBehavior = MediaState.Play;
}

I am currently working with WmpLib.WindowsMediaPlayer () but when I click on play after clicking pause the music starts again at the beginning instead of continuing and I do not understand why.
Could someone explain to me?
private void play_Click(object sender, EventArgs e)
{
player = new WMPLib.WindowsMediaPlayer();
player.URL = SoundFilePath;
player.controls.play();
}
private void pause_Click(object sender, EventArgs e)
{
player.controls.pause();
}
I have a problem with backgroundworker. I wrote program to copying files from local disc to network disk and I want to shows progressbar spinning in circles (not shows progress) when process is running.When I set backgroundworker into empty button everything works fine, but when I set backgroundworker into button which have function to coping files progressbar shows when copying process is finished. Why and how can I solved that? Below code.
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
circularProgressBar1.BeginInvoke(new MethodInvoker(sd));
}
public void sd()
{
circularProgressBar1.Visible = true;
circularProgressBar1.Enabled = true;
circularProgressBar1.Style = ProgressBarStyle.Marquee;
}
private void backgroundWorker1_ProgressChanged(object sender,
ProgressChangedEventArgs e)
{
circularProgressBar1.Value = e.ProgressPercentage;
}
private void backgroundWorker1_RunWorkerCompleted(object sender,
RunWorkerCompletedEventArgs e)
{
MessageBox.Show("End");
}
private void button1_Click_1(object sender, EventArgs e)
{
backgroundWorker1.RunWorkerAsync();
}
private void copy_Click(object sender, EventArgs e)
{
backgroundWorker1.RunWorkerAsync();
List<string> pathList = new List<string>();
// for example add 1000 path
pathList.add("C:\test\2.jpg");
pathList.add("C:\test\3.jpg");
foreach(string in in pathList)
{
File.Copy(in,"D:\test2",true);
}
}
You need to put the File.Copy in backgroundWorker1_DoWork - this is where the background work is done.
You may activate the circularProgressBar before the call to backgroundWorker1.RunWorkerAsync and disable it in backgroundWorker1_RunWorkerCompleted.
My application has one button one text box and a webbrowser control which is going to navigate at google.com at form load event.
If I am setting the text attributes to the google textbox in webBrowser1_DocumentCompleted method after clicking the button I am able to invoke google search button.
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.Navigate("https://www.google.co.in/?gfe_rd=cr&ei=u6PkV4X9LovZ8Aec7bI4&gws_rd=ssl");
webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
}
void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
textElement = webBrowser1.Document.All.GetElementsByName("q")[0];
textElement.SetAttribute("value", "facebook");
}
private void btnLogin_Click(object sender, EventArgs e)
{
ele = webBrowser1.Document.All.GetElementsByName("btnK")[0];
ele.InvokeMember("click");
}
If I am setting the text attributes to the google textbox in btnLogin_Click method after clicking the button i am not able to invoke google search button.
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.Navigate("https://www.google.co.in/?gfe_rd=cr&ei=u6PkV4X9LovZ8Aec7bI4&gws_rd=ssl");
webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
}
void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
textElement = webBrowser1.Document.All.GetElementsByName("q")[0];
}
private void btnLogin_Click(object sender, EventArgs e)
{
textElement.SetAttribute("value", "facebook");
ele = webBrowser1.Document.All.GetElementsByName("btnK")[0];
ele.InvokeMember("click");
}
Where I am going wrong please suggest me.
Here's what H have so far:
private void button1_Click(object sender, EventArgs e)
{
button3.BackgroundImage = slideshow_test.Properties.Resources.ai_yori_aoshi_5370;
}
private void button2_Click(object sender, EventArgs e)
{
button3.BackgroundImage = slideshow_test.Properties.Resources.AiYoriAoshi_feature;
}
private void button3_Click(object sender, EventArgs e)
{
audio.Stop();
if (button1.Enabled == true)
{
timer1.Stop();
pictureBox1.Visible = false;
System.Diagnostics.Process.Start("http://www.watchcartoononline.com/anime/ai-yori-aoshi-guide");
if (button2.Enabled == true)
{
timer1.Stop();
pictureBox1.Visible = false;
System.Diagnostics.Process.Start("http://www.watchcartoononline.com/anime/ai-yori-aoshi-enishi-guide");
}
}
}
this is only my test so far but what i want to do is change what button 3 does, i.e. if button 1 is clicked button three will open webpage 1, if button2 is clicked button 3 will open webpage 2, button 3's image will change depending, but what im finding with what i have done so far is that it opens BOTH pages AT THE SAME TIME ... how to i prevent this? i have tried if, else and else if, same result every time.
Both of your buttons are enabled, you are checking to see if the buttons are enabled or disabled (clickable or not), not which one has been clicked.
also:if (button2.Enabled == true)
is nested in the first conditional, I'm not sure if that's what you want.
You can: disable buttons 1 and 2 after their clicked so that, for instance button2.Enabled will now = false; (but then you will not be able to reclick that button)
More sophisticated, but better, is to use a delegate for the button3, and assign them in your button1_Click and button2_Click events. Something like this:
private void button1_Click(object sender, EventArgs e)
{
button3.BackgroundImage = slideshow_test.Properties.Resources.ai_yori_aoshi_5370;
button3.Click += new EventHandler(this.Button3_Click_First);
}
private void button2_Click(object sender, EventArgs e)
{
button3.BackgroundImage = slideshow_test.Properties.Resources.AiYoriAoshi_feature;
button3.Click += new EventHandler(this.Button3_Click_Second);
}
void Button3_Click_First(Object sender,
EventArgs e)
{
// When the button is clicked,
// change the button text, and disable it.
timer1.Stop();
pictureBox1.Visible = false;
System.Diagnostics.Process.Start("http://www.watchcartoononline.com/anime/ai-yori-aoshi-guide");
}
void Button3_Click_Second(Object sender,
EventArgs e)
{
timer1.Stop();
pictureBox1.Visible = false;
System.Diagnostics.Process.Start("http://www.watchcartoononline.com/anime/ai-yori-aoshi-enishi-guide");
}
You may also have to check and make sure an event handler was not previously assigned, in calse someone clicks button1, then button2, then button1 ect. This is described here: Removing event handlers
You can handle your problem by storing the URL of the webpage in a private field, setting it when buttons 1 or 2 are clicked and reading from it after clicking button 3.
private string _address = null;
private void button1_Click(object sender, EventArgs e)
{
// do other stuff
_address = "http://www.watchcartoononline.com/anime/ai-yori-aoshi-guide";
}
private void button2_Click(object sender, EventArgs e)
{
// do other stuff
_address = "http://www.watchcartoononline.com/anime/ai-yori-aoshi-enishi-guide";
}
private void button3_Click(object sender, EventArgs e)
{
if (_address != null)
{
audio.Stop();
if (button1.Enabled || button2.Enabled)
{
timer1.Stop();
pictureBox1.Visible = false;
System.Diagnostics.Process.Start(_address);
}
}
}
I wasn't sure if all the code in button3_Click is necessary, so I cleared it up a little. I might be a bit off, though.
button.Enabled is always true for all buttons by default unless you set it to false. So you cannot use button1.Enabled property to check which button is pressed. try below approach.
protected void Button1_Click(object sender, EventArgs e)
{
ViewState["Button1Clicked"] = true;
}
protected void Button2_Click(object sender, EventArgs e)
{
ViewState["Button1Clicked"] = false;
}
protected void Button3_Click(object sender, EventArgs e)
{
if ((bool)ViewState["Button1Clicked"])
{
//open webpage2 code comes here
}
else
{
//open webpage2 code comes here
}
}
I want to click on a button and make a text block and another button appear. I managed to make the text block appear. How do I make the button appear. I can't seem to find a function that does so. Also, does it need to be a different private void statement. So far I have:
private void one_Click(object sender, RoutedEventArgs e)
{
oneBlock.Text = "one";
}
private void one_Click(object sender, RoutedEventArgs e)
{
one_Trans.ClickMode = "two";
}
You can do something like this:
private void button1_Click(object sender, RoutedEventArgs e)
{
button2.Visibility = Visibility.Visible;
}
XAML:
<Button x:Name="button2" Content="Button" Visibility="Collapsed"/>
More here: http://msdn.microsoft.com/en-us/library/system.windows.visibility(v=vs.95).aspx
use
protected void button1_Click(object sender, EventArgs e)
{
button2.Visible=true;
}
on the click event of button1
Put everything into the same event
private void one_Click(object sender, RoutedEventArgs e)
{
oneBlock.Text = "one";
one_Trans.ClickMode = "two";
button1.Visible = true;
}
