Sure, no problem. Though I don't know if I should post the whole one ore not
^^. anyway. here it is :

	protected virtual void OnCovertClicked (object sender, System.EventArgs e)
	{
		try
		{
		this.SelectFolder.Sensitive = false;
		this.FileAdd.Sensitive = false;
	    this.RemoveFile.Sensitive = false;
		this.ClearAll.Sensitive = false;
		this.entry1.Sensitive = false;
		this.combobox1.Sensitive = false;
		this.combobox2.Sensitive = false;
		this.menubar1.Sensitive = false;
			
		selectedFile = String.Empty;
		newselectedFile = String.Empty;
		oldselectedFile = String.Empty;

		while(this.menuListStore.GetIterFirst(out iter) != false) 
		{
		format = this.combobox1.ActiveText;
		quality = this.combobox2.ActiveText;
		iter = new TreeIter();
		
		menuListStore.GetIterFirst(out iter);
		selectedFile = (string)menuListStore.GetValue(iter, 0);
		
		if(selectedFile.Substring(selectedFile.Length -4) == "flac") number+=1;
				
		oldselectedFile =
selectedFile.Replace(selectedFile.Substring(selectedFile.Length - number),
format);
		selectedFile = selectedFile.Replace(" ", "\\ ");
		newselectedFile =
selectedFile.Replace(selectedFile.Substring(selectedFile.Length - number),
format);
				
		if(selectedFile.Substring(selectedFile.Length -4) == "flac") number-=1;
		
		string command = "ffmpeg -y -i " + selectedFile + " -ab " +
quality.Replace("b/s", " ") + newselectedFile; 		
					
		if (System.IO.File.Exists(oldselectedFile))
	    {
			MessageDialog md = new MessageDialog (this,
				                      DialogFlags.DestroyWithParent,
                                   MessageType.Question, 
                                      ButtonsType.YesNo, newselectedFile + "
already exits. Overwrite it?");
			
			ResponseType result = (ResponseType)md.Run ();
			
			if (result == ResponseType.Yes)
			{
			md.Destroy();
			this.Convert.Sensitive = false;
			proc = Process.Start(command);
			}	
			else
			{
			this.FileAdd.Sensitive = true;
			this.Convert.Sensitive = false;
			md.Destroy();		
			}
		}
		else
		{
		this.Convert.Sensitive = false;
		proc = Process.Start(command);
		}
		this.menuListStore.GetIterFirst(out iter);
		this.menuListStore.Remove(ref iter);

		}
//		GLib.Idle.Add(delegate {
//		if (proc.HasExited) {
//				
//		MessageDialog mdg = new MessageDialog(this,
DialogFlags.DestroyWithParent, MessageType.Info, ButtonsType.Ok, "Encoding
finished");
//		mdg.Run();
//		mdg.Destroy();
//        
//        return false; // Remove this delegate from the idle list.
//    }
//
//    return true; // Run this delegate again when idle.
//}); 
		proc.EnableRaisingEvents = true;
			proc.Exited += delegate {
				Application.Invoke(delegate {
        		MessageDialog mdg = new MessageDialog(this,
DialogFlags.DestroyWithParent, MessageType.Info, ButtonsType.Ok, "Encoding
finished");
		mdg.Run();
		mdg.Destroy();
    });
}; 

			
		this.FileAdd.Sensitive = true;
		this.Convert.Sensitive = false;	
		this.SelectFolder.Sensitive = true;
		this.entry1.Sensitive = true;
		this.combobox1.Sensitive = true;
		this.combobox2.Sensitive = true;
		this.menubar1.Sensitive = true;
			
	}
		catch(Exception ee)
		{
			Console.WriteLine(ee);
		}
	}


In my eyes it's very ugly code and beside my problem here I would appreciate
any suggestions ;)
Thx :D
