Loop URL to download PDF file.

Sai Reddy

Hi,

I have a requirement to download PDF's which come from the following url.

http://ceoaperms.ap.gov.in/Electoral_Rolls/Popuppage.aspx?partNumber=11&roll=EnglishMotherRoll&districtName=DIST_02&acname=AC_013&acnameeng=A013&acno=13&acnameurdu=013

When i browse the above URL , it asks me to enter CAPTCHA then i need to download the pdf that needs to be stored in particular folder.

In the URL partNumber=11 , i need to loop it till 100. How to automate it?

Please help me to solve it. Thanks in advance.

You can probably use this if you have direclty pdf path
Change your browser directory to download path & Run this code it will automatically download all files into your browsers folder

If you have option to enter captcha Than you can use belwo method accordingly
private void BtnDownload_Click(object sender, RoutedEventArgs e)
{
    using (WebClient wc = new WebClient())
    {
        wc.DownloadProgressChanged += wc_DownloadProgressChanged;
        wc.DownloadFileAsync (
            // Param1 = Link of file
            new System.Uri("http://ceoaperms.ap.gov.in/Electoral_Rolls/Popuppage.aspx?partNumber=11&roll=EnglishMotherRoll&districtName=DIST_02&acname=AC_013&acnameeng=A013&acno=13&acnameurdu=013"),
            // Param2 = Path to save
            "D:\\Reports\\Report1.pdf"
        );
    }
}
// Event to track the progress
void wc_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
    progressBar.Value = e.ProgressPercentage;
}
