Hi lan,
Below is the sample function which doing copy paste in my case.
I am copying data directly by column, not reading each & every value.
Data is too big in heavy.
def copyPaste(self,ws):
# todo
self.ws = ws
startRowPaste = self.headerRow
self.col = self.getColToPaste(ws)
rngPaste = ws.Cells( startRowPaste, self.col)
self.datafile.openDataFile()
self.datafile.ws.Activate()
rngCopy = self.datafile.ws.Cells(self.datafile.headerRow,self.colCopy)
rngCopy = self.datafile.ws.Range(rngCopy,rngCopy.End(util.Xl.xlDown))
rngCopy.Copy()
ws.Activate()
ws.Paste(Destination=rngPaste)
self.dataRange = self.getDataRange()
self.datafile.closeDataFile()
pass
