EditGraph Method

Summary

Registers the current graph and runs the DirectShow GraphEdit utility.

Syntax

C++/CLI

public virtual void EditGraph()

public: 
virtual void EditGraph();

Remarks

Registers the current graph and runs the DirectShow GraphEdit utility. This method displays a modal dialog box indicating that the graph has been registered. The current thread is suspended during this time. The toolkit then attempts to invoke the GraphEdit utility from the DirectShow SDK. You can use GraphEdit's "Connect" menu option to view the registered graph. When finished, exit GraphEdit, and click the dialog's OK button to continue program execution.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public ConvertCtrlForm _form = new ConvertCtrlForm(); 
 
public void EditGraphExample() 
{ 
   // reference the convert control 
   ConvertCtrl convertctrl = _form.ConvertCtrl; 
 
   // set the input and output file names 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_Source.mpeg"); 
   string outFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_EditGraphExample.mpg"); 
 
   try 
   { 
      // set the source and target files 
      convertctrl.SourceFile = inFile; 
      convertctrl.TargetFile = outFile; 
 
      // set the preview 
      convertctrl.Preview = true; 
 
      // set a video compressor 
      convertctrl.VideoCompressors.Mpeg4.Selected = true; 
 
      // register the graph for GraphEdit  
      // you should see a message box that says the graph is registered  
      // after this message displays you can open GraphEdit and Connect to Remote Graph 
      convertctrl.EditGraph(); 
 
      // run the convert 
      convertctrl.StartConvert(); 
   } 
   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(); 
 
   // set the result 
   _result = true; 
}
