问题 I am using a C# application where I have to create a playlist. At the end of this application on form close I want to delete this play list which has been created.

问题 I am using AxWindowsMediaPlayer component in my WinForm application. I noticed that when I set URL to file I want to play and call Ctlcontrols.play() command there is an eg. 250ms delay before movie starts to play.

问题 I'm basically trying to play a video on Axwindowsmediaplayer from my resources, so it could be seen from other computers besides mine (just taking it from my Resources). And I came up with this.
