Have a look at: http://msdn2.microsoft.com/en-us/library/system.collections.ienumerator(VS.80).aspx In particular: An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying, or deleting elements, the enumerator is irrecoverably invalidated and the next call to MoveNext or Reset throws an InvalidOperationException And: http://www.yoda.arachsys.com/csharp/threads/winforms.shtml Regards

Is it http://www.albahari.com/threading/ ?

I am not sure I understood everything but ... aren't you trying to iterate through listview items with a thread while eventually modifying the same collection with another one (the main one) ?

Why don't you use the factory pattern :)

6 div 4 = 6 / 4 6 mod 4 = 6 % 4

Something like this?

    public partial class CustomPanel : Panel
    {
        Color color;
        public CustomPanel()
        {
            InitializeComponent();
            color = Color.FromArgb(100, Color.Blue);
        }
        protected override CreateParams CreateParams
        {
            get
            {
                CreateParams cp = base.CreateParams;
                cp.ExStyle |=  0x00000020; //WS_EX_TRANSPARENT
                return cp;
            }
        }

        protected override void OnPaintBackground(PaintEventArgs e){}
        
        protected override void OnPaint(PaintEventArgs e)
        {
           
            using (Brush brush = new SolidBrush(color))
            {
                e.Graphics.Clear(Color.Transparent);
                e.Graphics.FillRectangle(brush, this.ClientRectangle);
            }
        }
    }

Hi, Have you thought of creating another Form hosting your Panel ? Regards

Hi, Comments about what ?

Hi, what about Rational PurifyPlus ? Regards

FileInfo.MoveTo should do the trick

chkListBox.SelectedIndex = index; chkListBox.SetItemCheckState(index, CheckState. ...);

In (ServerInfo)(myServerArrayList[0]).strServerName ... It won't if the cast is applied after having attempted to retrieve the strServerName in (myServerArrayList[0]) which is recognized as an object type instance.

Since anything derived from object can be stored in your ArrayList, Intellisense does not "know" what kind of object is stored in the 0th position. You need to cast it before: ((ServerInfo)myServerArrayList[0]). ... or use something more appropriate than ArrayList. Try List<ServerInfo> :)

Take three different sample points A, B, C visited by your mouse. Compute the vectors AB = v1 (v1x, v1y) , AC = v2 (v2x, v2y). Sign of v2x* v1y - v1x * v2y will tell you the result: positive = clockwise. 0 = aligned visited points negative ... Regards

No, you're wrong. MIDI has no concept of the same note living in more than one place, so it doesn't contain any info about how to play the note on guitar.

Why am I wrong, just because I say that coverting MIDI to TAB would not be entirely a rendering detail ? I was just pointing out that there are different rendering possibilities and that it is not as simple as that.

No system that I have seen does a good job of choosing 'default' fingerings, you always end up having to edit them.

I was talking about that algorithm. Regards

It is not totally a rendering detail since each note can be rendered in several places :)

A solution may be copying the arraylist and iteration over the copied version :)

Use the WebBrowser control :)

It is sad to read this kind of statements here. Helping each other is the main purpose of these forums. Not comparing IT staffs :(

Can you be a bit more specific?
