StreamCount Property

Summary

Gets the total number of streams in the list.

Syntax

C++/CLI

public int StreamCount {get;}

public: 
property int StreamCount { 
   int get(); 
}

Property Value

A value that represents the total number of streams in the list.

Remarks

Using the WMMutualExclusion.StreamCount as a zero-based index, the GetStream method can then be used to get the stream numbers for each stream in the object's stream list. For more information, refer to the Microsoft documentation for IWMMutualExclusion.GetStreams.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public ConvertCtrlForm _form = new ConvertCtrlForm(); 
public void RemoveStreamExample() 
{ 
   ConvertCtrl convertctrl = _form.ConvertCtrl; 
   string inWMProfile = Path.Combine(LEAD_VARS.MediaDir, "WMCustomProfile.xml"); 
   string outWMProfile = Path.Combine(LEAD_VARS.MediaDir, "WMCustomProfile_StreamRemoved.xml"); 
 
   try 
   { 
      WMProfileManager manager = new WMProfileManager(); 
 
      // load the custom profile 
      convertctrl.WMProfile = manager.LoadProfileByData(File.ReadAllText(inWMProfile)); 
 
      // remove last stream from the mutual exclusion 
      WMMutualExclusion excl = convertctrl.WMProfile.GetMutualExclusion(0); 
      int streamCount = excl.StreamCount; 
      excl.RemoveStream(excl.GetStream(streamCount - 1)); 
 
      // save the profile 
      File.WriteAllText(outWMProfile, manager.SaveProfileEx(convertctrl.WMProfile, WMProfileType.Default)); 
      _result = true; 
 
      // dispose of the manager 
      manager.Dispose(); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
 
   // we'll loop on the state and pump messages for this example. 
   // but you should not need to if running from a Windows Forms application. 
   while (convertctrl.State == ConvertState.Running) 
      Application.DoEvents(); 
} 
 
static class LEAD_VARS 
{ 
   public const string MediaDir = @"C:\LEADTOOLS23\Media";
