Using VBA to submit form and download data

Hi all,

My objective is to automate the download the current futures data from the website www.nseindia.com. For this, I tried using the following code:

Sub Test1()


Dim IE As Object
Set IE = CreateObject("InternetExplorer.Application")


IE.Visible = True
IE.Navigate "http://www.nseindia.com/products/content/derivatives/equities/historical_fo.htm"


Do While IE.Busy


Application.Wait DateAdd("s", 1, Now)


Loop


Set doc = IE.document


doc.GetElementById("instrumentType").Value = Range("A2")


doc.GetElementById("symbol").Value = Range("B2")
'doc.GetElementById("year").Value = Range("C2")
'doc.GetElementById("expiryDate").Value = Range("D2")


'doc.GetElementById("rdDateToDate").******* = "makeReadonly()"


'doc.GetElementById("fromDate").Value = Range("E2")
'doc.GetElementById("toDate").Value = Range("F2")






'doc.GetElementById("getButton").Click






End Sub

A2 = FUTIDX
B2 = NIFTY
C2 = 2000
D2 = 29-06-2000
E2 = 12-06-2000
F2 = 29-06-2000


After selecting the first drop, down nothing else works. My research led me to understand that this cannot be done using IE. Accordingly, I tried installing a Selenium wrapper and then tried with the following code:

Sub ChromeAutomation()
Chrome.Start: Chrome.Get "https://www.google.it/"
End Sub

However, excel throws up an error at .start.

The volume of data to be downloaded does not lend itself to manual work and thus I'd be grateful for any solutions to achieve the desired objective. Many thanks in advance.
 

Excel Facts

Copy formula down without changing references
If you have =SUM(F2:F49) in F50; type Alt+' in F51 to copy =SUM(F2:F49) to F51, leaving the formula in edit mode. Change SUM to COUNT.

Hey,

Many thanks for this. However, the code does not seem to work for me.

Could it be that my settings are not optimal?

All I reach is a point where the submit button is to be clicked - but doesnt get clicked and also an additional sheet gets inserted in the master workbook.

Thanks again for helping out.

Hi,

Add the following line before the line "
Call TransferData(doc, Sheets("Sheet2"))"​
[FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif][FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif] Do
DoEvents
Loop While IE.Busy Or (IE.ReadyState <> 4)[/FONT]

Sometime the VBA code is to fast for the web site.
The table result is copied on Sheet2

Thanks again for taking the time on this.

I took a screenshot of what I can see (I had removed the IE.Quit), but not sure how to post it here.

Essentially, the same problem occurs. As an additional observation, the expiry date also does not get selected.

Not sure how to resolve this.

Hi,

I did some small modification on the code to wait for internet.

Hi Rino702,

Many thanks for helping out.

I tried it on two different computers and the same issue persists...

Can this be done using Firefox or Chrome?

Hi Adhwn,

It works fine for me, I did test it many times.
I can suggest to increase delay from 1 second to 2 or 3 seconds before the Call TransferData…

For Firefox or Chrome, you will need to install Selenium wrapper (
https://github.com/florentbr/SeleniumBasic), this product is more complex to use that internet explorer ide.

Regards,
Rino
