C#写COM组件，JS调用控件

由 微笑、不失礼 提交于 2020-03-07 05:02:31
1、c#2005中新建项目，类型为类库，项目名为AddCom确定。 　　配置：右键点击解决方案资源管理器中的AddCom，选择“属性”，选择“生成”，选择“为COM Interop注册(_P)” 2、打开AssemblyInfo.cs文件，设置[assembly: ComVisible(true)]，如果不改则不能被其他程序调用 3、编写com组件会用到guid(全球唯一ID)，编写com组件必须要用到。c#会默认生成一个放在AssemblyInfo.cs，如没有生成，网上下一个生成guid的软件，有很多呢。 4、c#中源代码如下，按如下方法编写代码后生成工程，/bin/release中得到AddCom.dll。 using System; using System.Collections.Generic; using System.Text; using System.Runtime.InteropServices; namespace AddCom { [Guid("298D881C-E2A3-4638-B872-73EADE25511C")] public interface AddComInterface { [DispId(1)] int iadd(int a, int b); } [Guid("2C5B7580-4038-4d90-BABD-8B83FCE5A467")

C# Windows Forms capture a image from embeded Windows Media Player

由 家住魔仙堡 提交于 2020-01-02 10:18:30
问题 I have a windows forms application written in C# which uses embedded Windows Media Player (AxInterop.WMPLib.dll and WMPLib.dll) to play some video files. Now I need to add an option to capture image from video on button click. If I set the windowless option to true, I am able to capture an image of a video, but when I set the windowless option to true I don't see a video image on some computers. Without the windowless option I only get a black screen with this code: System.Drawing.Image ret =

由 人盡茶涼 提交于 2019-12-29 08:09:33
问题 As far as I know Windows Media Player 10 is the minimum requirement for WPF MediaElement to work. What is a decent way to programmatically (from .NET) check if WMP is present, and its version? 回答1: The method I used in my installer is to check this registry value: HKLM Software\Microsoft\MediaPlayer\PlayerUpgrade PlayerVersion The PlayerVersion value will be set to a string like "10,0,0,0". (Note that commas, not periods, are used to separate the numbers.) You need to extract the first number

Seeking in .avi file using C#

由 人盡茶涼 提交于 2019-12-24 07:10:09
问题 First of all, I'm new to C#, so bear with me. I am making an application, that shows an .avi file in windows media player like this: private void button1_Click(object sender, EventArgs e) { axWindowsMediaPlayer1.URL = @"C:BlaBla\Family Guy\Season 10\S10E16.HDTV.x264-LOL.avi"; } I've found out that you cant fastforward or fastrewind in an .avi file, because it's not indexed. But using the WMP-slider of axWindowsMediaPlayer1, you can set the file to play at a specific point. For instance, start

Java control Windows Media Player with Java

由 ぐ巨炮叔叔 提交于 2019-12-23 16:34:15
问题 I have seen some Java servers wich can control WMP with an android device or such. But how do you make a server that controls WMP. What do you need for it? Thanks. 回答1: Windows Media Player supports UPnP for server discovering and DLNA for remote controlling. Say if you want to create a client app (Android or whatsoever using Java) to remote control Windows Media Player: Use UPnP to discover available WMP server on network with zero configuration. Use DLNA to remote control available WMP

Do VLC or WMP ActiveX controls accept Stream objects?

由 寵の児 提交于 2019-12-22 14:40:26
问题 I've got a WCF service that stories media files and returns them to consuming applications in the form of a Stream object. The issue arises when the consuming application wants to stream the media using MediaElement. As you all know, MediaElement doesn't accept Stream objects. Can I get around this by using a VLC or WMP ActiveX control? Would either of these two controls allow me to play streaming media? 回答1: Both of those two activex controls support various types of streaming media, but
