Syntax


public static void CopyText(this WealthScript obj, string text)
public static void CopyObject(this WealthScript obj, object ob)

public static void CopyText(string text)
public static void CopyObject(object ob)

Parameter Description

text	A string to be copied to clipboard
obj	Value of type object to be copied to clipboard

Description

Although .NET has support for copying to clipboard, making it from Wealth-Lab would be pretty tricky. For your convenience, CopyText is a simple static method for copying a text string to Windows clipboard. Its companion method CopyObject was designed to copy any data (not just text) as type object.

Examples

Example below copies to clipboard a block of text containing a header and series of OHLC values and the 20-bar SMA value at each bar, separated with tabs.

Example using C# extension methods:


using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using WealthLab;
using WealthLab.Indicators;

namespace WealthLab.Strategies
{
	public class ClipboardDemo : WealthScript
	{
		protected override void Execute()
		{
			SMA sma = SMA.Series( Close,20 );
			char sep = '\t';
			string s = "Date" + sep + "Open" + sep + "High" + sep + "Low" + sep + "SMAbar \n";
			
			for(int i = sma.FirstValidValue; i < Bars.Count; i++)
			{
				s += ( Datei.ToShortDateString() + sep + 
					Openi + sep + Highi + sep + Lowi + sep + Closei +
					sep + Bars.FormatValue( smai ) + "\n" );
			}
			
			this.CopyText( s );
		}
	}
}

Advanced example

Copying formatted text and chart image to clipboard and creating a new RTF document (open in Wordpad or Word):


using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using WealthLab;
using WealthLab.Indicators;
using System.Windows.Forms;

namespace WealthLab.Strategies
{
	public class MyStrategy : WealthScript
	{
		private void PasteBitmap(RichTextBox richTextBox, Bitmap myBitmap)
		{
			// Copy the bitmap to the clipboard.
			this.CopyObject(myBitmap);

			DataFormats.Format myFormat = DataFormats.GetFormat(DataFormats.Bitmap);

			if(richTextBox.CanPaste(myFormat))
				richTextBox.Paste(myFormat);
		}
		
		protected override void Execute()
		{
			const string newLine = "\n";
			
			// We're using a RichTextBox control to save some formatted text and an image as RTF
			RichTextBox richTextBox1 = new RichTextBox();
			
			// Location of your output RTF document
			string location = @"c:\Temp\test.rtf";

			// Define new font style
			Font font = new Font("Times New Roman", 14, FontStyle.Bold);
			richTextBox1.SelectionFont = font;
			richTextBox1.SelectionColor = Color.Red;
			
			// A text sentence
			richTextBox1.AppendText("Let me share a chart with you..." + newLine);
			
			// Take a screenshot
			Bitmap bm = GetChartBitmap( 300, 200 );

			// Paste the screenshot as bitmap
			PasteBitmap( richTextBox1, bm );
			
			// Define yet another font style
			Font font2 = new Font("Arial", 12, FontStyle.Bold);			
			richTextBox1.SelectionFont = font2;
			richTextBox1.SelectionColor = Color.Blue;
			
			// A text sentence
			richTextBox1.AppendText(newLine + "This was my Wealth-Lab chart!");			
			richTextBox1.SaveFile(location, RichTextBoxStreamType.RichText);

		}
	}
}

Legacy syntax example:

Note: since the function is marked as static, you don't have to create an instance of the MyClipboard class that contains it:


using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using WealthLab;
using WealthLab.Indicators;
using Community.Components; /*** Requires installation of Community.Components Extension from www.wealth-lab.com > Extensions ***/

namespace WealthLab.Strategies
{
	public class ClipboardDemo : WealthScript
	{
		protected override void Execute()
		{
			SMA sma = SMA.Series( Close,20 );
			char sep = '\t';
			string s = "Date" + sep + "Open" + sep + "High" + sep + "Low" + sep + "SMAbar \n";
			
			for(int i = sma.FirstValidValue; i < Bars.Count; i++)
			{
				s += ( Datei.ToShortDateString() + sep + 
					Openi + sep + Highi + sep + Lowi + sep + Closei +
					sep + Bars.FormatValue( smai ) + "\n" );
			}
			
			MyClipboard.CopyText( s );
		}
	}
}
