Use Mediaplay to write a player, mediaplay player

We know that android has limited video playback capabilities .. Let's start with a Demo.

An immature player, http://www.eoemarket.com/soft/370334.html, is being completed.

How can this problem be solved when Windows Media Play is set as the default player on the computer?

Haha, Windows Media Player may not be able to play all audio and video files. If you have to change it, select a file you want to open by default, such *. right-click the wma file and select "open mode" and "Select Program". There will be "Recommended programs" and "other programs". Find your Media Player and select it, then, click "open this file with the selected program" and click "OK! So... in the future, all wma will be opened using Media Player ...... hey hey... we recommend that you use media player classic (MPC). Now I am using QQ audio and video, which is more convenient :)
 
A c # MP3 player created by referencing Mediaplayer

Create a new form, open the toolbar on the visual interface, right click the toolbar -- select item -- com component --- window mediaplayer -- OK. Drag the mediaplayer control in the toolbar to the blank form area, drag an openfiledialog control to the form interface, and drag a buttom control to the mediaplayer. Double-click the buttom control and copy the following code.

String resultFile = "";
OpenFileDialog openFileDialog1 = new OpenFileDialog ();
OpenFileDialog1.InitialDirectory = "D :\\";
OpenFileDialog1.Filter = "All files (*. *) | *. * | wmv files (*. wmv) | *. wmv ";
OpenFileDialog1.FilterIndex = 2;
OpenFileDialog1.RestoreDirectory = true;
If (openFileDialog1.ShowDialog () = DialogResult. OK)
ResultFile = openFileDialog1.FileName;
AxWindowsMediaPlayer1.URL = resultFile;
