问题描述

先生，

告诉我在Visual Studio中使用COM。 clsid有什么用，在下面的代码中。请给我解决这个问题的方法。

 <  < span class =code-leadattribute> object     id   =  mediaplayer    classid   =  clsid：22d6f312-b0f6-11d0-94ab-0080c74c7e95    codebase   =  http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#version=5,1,52,701   < span class =code-attribute> standby   = 加载微软windows media player组件......    < span class =code-attribute> type   =  application / x-oleobject    width   =  320    height   =  310 >  
 <   param     name   =  filename    value   ='  < ;％ = str ％> '  /  >  
 <   param     name   =  animationatstart    value   =  true  /  >  
 <   param    名称  =  transparentatstart    value   =  true  /  >  
 <   param     name   =  autostart    value   =  true  /  >  
 <   param     name   =  showcontrols    value   =  true  /  >  
 <   param     name   =  ShowStatusBar    value   =  true  /  < span class =code-keyword>>  
 <   param    名称  =  windowlessvideo    value   =  true  /  >  
 <   embed     src   ='  <％ = str ％> '   自动启动  =  true    showcontrols   =  true    showstatusbar   =  1    bgcolor   =  white    width   =  320    height   =  310  /  >  
 <   / object  >  

解决方案

这不是在<$ c中使用 COM $ c> Visual Studio 。也就是说，我相信，在 HTML 页面中嵌入了对象的ActiveX（例如，参见\"HTML对象标签 [ ^ ]。

CLSID 是实际的 COM 对象的标识符（在您的情况下为 Mediaplayer ），例如参见\"COM类对象和CLSID[ ^ ]。

Hi sir,
Tell me the use of COM in visual studio. What is the use of clsid, in the below code. Kindly give me the solution for this problem.

<object id="mediaplayer" classid="clsid:22d6f312-b0f6-11d0-94ab-0080c74c7e95" codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#version=5,1,52,701" standby="loading microsoft windows media player components..." type="application/x-oleobject" width="320" height="310">
<param name="filename" value='<%=str %>'/>
<param name="animationatstart" value="true"/>
<param name="transparentatstart" value="true"/>
<param name="autostart" value="true"/>
<param name="showcontrols" value="true"/>
<param name="ShowStatusBar" value="true"/>
<param name="windowlessvideo" value="true"/>
<embed src='<%=str %>' autostart="true" showcontrols="true" showstatusbar="1" bgcolor="white" width="320" height="310"/>
</object>

解决方案

That is not the use of COM in Visual Studio. That is, I believe, an ActiveX embedded as object in a HTML page (see, for instance "HTML object TAG" at w3schools.com[^].
The CLSID is the actual COM identifier of the object (the Mediaplayer in your case), see, for instance "COM Class Objects and CLSIDs" at MSDN[^].
