First attempt at this: I created the Windows Media Player programmatically by adding the WMPLib as a reference in my project. I am trying to play a playlist using Windows Media Player in a ASP.Net web page (Visual Studio 2015). I cannot use the video tag used in examples for HTML 5 as I need to display .wmv, .mp4, .jpg formats in the control. When I run the code, no errors are displayed and I see an empty browser, what am I missing? Here is my sample code:
WMPLib.WindowsMediaPlayer Player;
protected void Page_Load(object sender, EventArgs e)
{
FileNames();
}
public void FileNames()
{
String[] extentions = { "*.wmv", "*.mp4", "*.jpg" };
List<string> files = new List<string>();
foreach (string filter in extentions)
{
files.AddRange(System.IO.Directory.GetFiles(@"C:\Documents\", filter));
}
foreach (string ss in files)
{
String name = System.IO.Path.GetFileName(ss);
Player = new WMPLib.WindowsMediaPlayer();
WMPLib.IWMPPlaylist playList = Player.newPlaylist("myPlayList", "");
playList.appendItem(Player.newMedia(name));
Player.currentPlaylist = playList;
Player.controls.play();
}
}
I am aware of the hard coded path which is not good practice, however I just need to get this displaying on my local machine. Thanks!
After two more weeks of research we managed to come up with a solution by toggling between different types of controls based on the content that needs to be displayed. To display PowerPoint slideshows, we converted all slides to images and then looped through the collection. Here is a snippet of the code in case someone else needs a bit of guidance with a similar issue:
<body>
<form id="form1" runat="server">
<%-- Video DIV --%>
<div runat="server" id="VidDiv" class="fullscreen-bg">
</div>
<%-- IMAGE DIV --%>
<div runat="server" id="container">
<div runat="server" id="containers">
</div>
<%-- this is where the code gets dynamically created --%>
</div>
</form>
</body>
<script src="Scripts/jquery-3.1.1.js"></script>
<script id="CallMyFunction" type="text/javascript">
var index = 1;
document.getElementById("VidDiv").style.display = "none";
var ImageCount = 1;
autoSlide();
function autoSlide() {
var x = document.getElementsByClassName("Images");
var video_player = document.getElementsByClassName("fullscreen-bd__video");
var count;
var video;
var videoSource = new Array(), vids, i;
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
if (index > x.length) {
index = 1
}
x[index - 1].style.display = "block";
count = x.length;
if (ImageCount <= count) {
index++;
ImageCount = 1 + ImageCount;
setTimeout(autoSlide, 8000);
}
else {
//this is where we should switch from image div to video div
document.getElementById("container").style.display = "none";
document.getElementById("VidDiv").style.display = "block";
//create a counter to check the number of video tags
video = document.getElementsByTagName('video'), numVideos = video.length;
for (i = 0; i < numVideos; i++) {
videoSource[i] = video.item(i).src;
document.getElementById("myVideo" + i).style.display = "none";
}
var videoCount = 0;
if (videoCount <= numVideos -1) {
function videoPlay(videoNum) {
if (videoCount > 0)
{
document.getElementById("myVideo" + (videoCount - 1)).style.display = "none";
}
document.getElementById("myVideo" + videoCount).style.display = "block";
document.getElementById("myVideo" + videoCount).setAttribute("src", "" + videoSource[videoCount] + "");
document.getElementById("myVideo" + videoCount).load();

The code can obviously be improved and optimized, but this is the base we used to get our app working. Thanks for all the advice and input!
