Spotfire - mark records and send to clipboard - clipboard

Question

I'd like to create a Spotfire button action control that does the following
Select all rows in a table visualization
Send the selected rows to the clipboard
First step was handled pretty easily (borrowed from here). For the second step, I was unsuccessful in my initial attempts to send to clipboard with script (e.g. as suggested here). I was partially successful in a followup attempt by sending ctrl-c programatically to spotfire (see spotfired.blogspot.co.id/2014/04/pressing-keys-programatically.html).
Here's the [mostly] functioning code:
from Spotfire.Dxp.Application.Visuals import VisualContent
from Spotfire.Dxp.Data import IndexSet
from Spotfire.Dxp.Data import RowSelection
#Get table reference
vc = vis.As[VisualContent]()
dataTable = vc.Data.DataTableReference
#Set marking
marking=vc.Data.MarkingReference
#Setup rows to select from rows to include
rowCount=dataTable.RowCount
rowsToSelect = IndexSet(rowCount, True)
#Set marking
marking.SetSelection(RowSelection(rowsToSelect), dataTable)
#Script to send keystroke to Spotfire
import clr
clr.AddReference("System.Windows.Forms")
from System.Windows.Forms import SendKeys, Control, Keys
#Send keystroke for CTRL-C Copy-to-clipboard
SendKeys.Send("^c") #Ctrl+C
The code works as expected, except that I have to hit the button twice for the ctrl-c part of the script to work (i.e. hitting once results in marking all rows in the table visualization).
Another issue that I seemed to have resolved is that the originally suggested syntax to send the ctrl-c keystroke command was SendKeys.Send("(^+C)"). However, this didn't work, so I rewrote as SendKeys.Send("^c"), which does work, except only after I hit the button twice.
Any thoughts on how I could fix the issue of having hit the action control button twice?
A workaround could be to avoid sending keystrokes with script and revisit my first attempt code the copy-to-clipboard functionality, but my Ironpython skills are a limiting factor here.

Using the same post as reference I used this code to use the windows clipboard
tempFolder = Path.GetTempPath()
tempFilename = Path.GetTempFileName()
tp = mytable.As[TablePlot]()
writer = StreamWriter(tempFilename)
tp.ExportText(writer)
f = open(tempFilename)
html=""
for line in f:
html += "\t".join(line.split("\t")).strip()
html += "\n"
f.close()
import clr
clr.AddReference('System.Windows.Forms')
from System.Windows.Forms import Clipboard
Clipboard.SetText(html)

Thanks, sayTibco, code working for me, now. See below for updated version. Still curious to know how to better utilize SendKeys.Send(), but will make that the subject of a separate post after I have some time to experiment.
from Spotfire.Dxp.Application.Visuals import VisualContent, TablePlot
from Spotfire.Dxp.Data import IndexSet
from Spotfire.Dxp.Data import RowSelection
#get table reference
vc = mytable.As[VisualContent]()
dataTable = vc.Data.DataTableReference
#set marking
marking=vc.Data.MarkingReference
#setup rows to select from rows to include
rowCount=dataTable.RowCount
rowsToSelect = IndexSet(rowCount, True)
#Set marking
marking.SetSelection(RowSelection(rowsToSelect), dataTable)
#Copy marked records to Clipboard
import clr
import sys
clr.AddReference('System.Data')
import System
from System.IO import Path, StreamWriter
from System.Text import StringBuilder
#Temp file for storing the table data
tempFolder = Path.GetTempPath()
tempFilename = Path.GetTempFileName()
#Export TablePlot data to the temp file
tp = mytable.As[TablePlot]()
writer = StreamWriter(tempFilename)
tp.ExportText(writer)
f = open(tempFilename)
#Format table
html=""
for line in f:
html += "\t".join(line.split("\t")).strip()
html += "\n"
f.close()
#Paste to system Clipboard
clr.AddReference('System.Windows.Forms')
from System.Windows.Forms import Clipboard
Clipboard.SetText(html)
