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 + "SMA[bar] \n";
for(int i = sma.FirstValidValue; i < Bars.Count; i++)
{
s += ( Date[i].ToShortDateString() + sep +
Open[i] + sep + High[i] + sep + Low[i] + sep + Close[i] +
sep + Bars.FormatValue( sma[i] ) + "\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 + "SMA[bar] \n";
for(int i = sma.FirstValidValue; i < Bars.Count; i++)
{
s += ( Date[i].ToShortDateString() + sep +
Open[i] + sep + High[i] + sep + Low[i] + sep + Close[i] +
sep + Bars.FormatValue( sma[i] ) + "\n" );
}
MyClipboard.CopyText( s );
}
}
}
