Windows media player end of stream problem

When we were developing a web player for one of our customers, we used the windows media player component. While developing it we found out that the end of stream event is not firing at the end of the play. Finally we came up with this solution.
In here we used the “PlayStateChange” event of the media player in order to detect the end of stream.

bool isMediaEnded = false;
private void mPlayer_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
{

if (mPlayer.playState == WMPLib.WMPPlayState.wmppsMediaEnded)
{
isMediaEnded = true;
}
else if (mPlayer.playState == WMPLib.WMPPlayState.wmppsTransitioning)
{
if (isMediaEnded)
{
isMediaEnded = false;
// End of stream occurs here. Do what ever you want.

}
}
}

How to use the “ErrorProvider” control in a C# application

This is an example on how to use the “ErrorProvider” control in order to check whether there is something written in the textbox and validate a textbox .

Add a label with the name ‘label1’, a textbox with the name ‘txtText’ and a button with the name ‘btnValidate’ as given in the above form. Also add error provider control to the form with the name ‘errorProvider’. Rename the Form as ‘FormTextBoxValidator’.

Then add this method to the FormTextBoxValidator.cs to validate the textbox.

private bool textBoxValidate()
{

errorProvider.Clear();
if (txtText.Text.Trim() == "")
{
errorProvider.SetError(txtText, "Text should be non empty");
return false;
}
return true;
}

Then to the click event of the ‘ btnValidate’ add the following code.

private void btnValidate_Click(object sender, EventArgs e)
{
if (textBoxValidate())
{
MessageBox.Show("Content validated!");
}
}

When you run the application, and click the validate button without entering a text to the textbox, it will provide an error as follows.

If you enter some text to the textbox, it will validate the textbox.
