No, there isn't. It's always painted using the system colors.

No it's not, since any change you make there affects ALL applications and windows, not just your apps. Changing system-wide settings just to make your app look pretty will ultimately get your app uninstalled.

Don't use

foreach (string filename in filenames)
{
PlayMedia(filename);
}

Instead write an event. When one song is completed, fire that event within WndProc
if (lEventCode == EC_COMPLETE)
{
m_objMediaControl.Stop();
m_objMediaPosition.CurrentPosition = 0;
m_CurrentStatus = MediaStatus.Stopped;
UpdateStatusBar();
UpdateToolBar();

// Fire that event

}

Then clean up and start the next song. Hope it will help

Sorry friend,

Today I am in a bit hurry. Currently I am in my office. Smile | :)

You can consult any preliminary C# book on how to create an event and fire it. It is a very simple one. Sorry again, don't mind

based on what you have said, I created below delege method

public delegate void PlayNextFileEventHandler(string nextFile);
public event PlayNextFileEventHandler PlayNextFile;
private string file;

public string FileToPlay
{
get { return this.file; }
set
{
this.file = value;
if (this.PlayNextFile != null)
this.PlayNextFile(value);
}
}

codes in main

[STAThread]
static void Main()
{

Application.Run(new Form1());

Form1 frm = new Form1();
frm.PlayNextFile += new PlayNextFileEventHandler(queueMedia);
}

static void queueMedia(object source, MyEventArgs e)
{
string mediasource = "C:\\Test\\Media";
string[] filenames = Directory.GetFiles(mediasource);
foreach (string filename in filenames)
{
PlayMedia(filename);
}
}

not sure how to raise the event so that it plays next file. could someone please help?

how to generate 0's and 1's only through Random Class...

14-Jul-09 17:05

ok solved it. had to use enqueue and dequeue. thanks

Hi,
How to generate only 0's and 1's by loop through the condition. I have tried with Random Class like
private int RandomNumber(int min, int max)
{
Random random = new Random();
return random.Next(min, max);
}
Inside for loop i am having the following line;
int returnValue = RandomNumber(0, 1);

It's returning all 0's. Is any other method to use.

Thanks,
Subbu

13-Jul-09 2:02

Use

int returnValue = RandomNumber(0, 2); because it generates random numbers excluding the max

Thanks a lot Anindya.

One question. Is it possible to get 0's and 1's sequence (01010101010101...) like this?

Anindya Chatterjee13-Jul-09 2:48

Re: how to generate 0's and 1's only through Random Class...

13-Jul-09 2:48

Create a StringBuilder object. Append that random number to the object in an iteration. After desired iteration just use ToString() method of StringBuilder object and it will create a sequence like that.

Thanks

Don't create Random objects all the time, it makes no sense, since the Random class guarantees Next() will generate random numbers INSIDE a Random object, not AMONGST different Random objects. Instead create your Random object once, and keep a reference to it as a class member.

How to Use PropertyGrid for Complex Class

Anindya Chatterjee13-Jul-09 1:45

Re: How to Use PropertyGrid for Complex Class

13-Jul-09 1:45

Suppose I have the following class :

public class A
{
  public bool Boolean {get; set;}

  public List<B> ListOfB {get; set;}  
}

public class B
{
  public String StringValue {get; set;}

  public List<String> OneList {get; set;}

  public List<String> AnotherList {get; set;}
}

I want to expose the class A and under it the B class in a propertygrid. I have tried a lot of thing, but no help. May be I am missing something. What I did is as follows :

[DefaultProperty("ListOfB")]
public class A
{  
  [Browsable(false)]
  public bool Boolean {get; set;}

  [Category("Visuals")]
  [Description("YZYZYZ")]
  [MergableProperty(false)]
  [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
  [Localizable(true)]
  [Editor("System.Windows.Forms.Design.ListControlStringCollectionEditor, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", typeof(UITypeEditor))]
  [Editor(typeof(BListEditor), typeof(UITypeEditor))]
  public List<B> ListOfB {get; set;}

}

public class B
{
   public String StringValue {get; set;}

   [Editor("System.Windows.Forms.Design.StringCollectionEditor, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", typeof(System.Drawing.Design.UITypeEditor))]
   [Category("Visuals")]
   [Description("XXYZ")]
   [MergableProperty(true)]
   [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
   public List<String> OneList {get; set;}

   [Description("PPPWRT")]
   [MergableProperty(true)]
   [Editor("System.Windows.Forms.Design.StringCollectionEditor, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", typeof(System.Drawing.Design.UITypeEditor))]
   [Category("Visuals")]
   [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
   public List<String> AnotherList {get; set;}
}  

public class BListEditor : CollectionEditor
{
   public BListEditor()
     : base(typeof(List<B>  ) )
   { }

   protected override Type[] CreateNewItemTypes()
   {
      return new Type[] {typeof(B)};
   }

   protected override object SetItems(object editValue, object[] value)
   {
      // Cast the context into the expected control type
      A settings = (A)Context.Instance;
      // Let base class update the collection
      object ret = base.SetItems(editValue, value);
                        
      return ret;
   }
}

I have tried that but no luck. The propertygrid can take the value in collection editor but can't able to store the value. After inserting one B item taking all the data when you click OK nothing actually being inserted into the List of B in class A.

Please help me out.

Thanks in advance.

It sounds like the ExpandableObjectConverter might be what you need. You can look that up on MSDN, or Google for it (you'll get lots of hits).

Take a look at Add Custom Properties to a PropertyGrid[^], it shows several methods to get what it sounds like you want to do.
