if (pay1>=pay)
{
//Set the following values appropriately for your Bank/Service Provider
//String responseURL = "http://www.gwipg.stgeorge.com.au/";
String responseURL = "";
//To avoid processing duplicate payments, for this user, check the
//if ( Session.Contents[ "WEBPAYOBJECT" ] == null )
//{
webpay.client.Webpay w = new webpay.client.Webpay("10000xxx", "e:\\net.pfx", "yourpwd");
Session.Contents["WEBPAYOBJECT"] = w;
responseURL = processPayment(w);
String expdate = mm.SelectedValue + "/" + yy.SelectedValue;
obj.Insert(Convert.ToInt32(Session["MId"]), Convert.ToDecimal(amount.Text), ddlpaymentmethod.SelectedValue, cardName.Text, txtCardData.Text, cvc2.Text, expdate.ToString());
//}
Response.Redirect(responseURL);
}
else
{
lblpayment.Text = "Payment Should be greater than " + pay;
}
use the following function
private String processPayment(webpay.client.Webpay w)
{
System.Random randObj = new System.Random(5325);
w.setServers("www.gwipg.stgeorge.com.au");
w.setPort(3006); //use 3005 for testing
w.setValue("CLIENTID", "10000xxx");
w.setValue("INTERFACE", "CREDITCARD");
w.setValue("TRANSACTIONTYPE", "PURCHASE");
//Set the following values based on user input, or calculations from other parts of
//your application.
//Please consult your service provider's documentation for
//required and optional fields.
w.setValue("CARDHOLDER_NAME", cardName.Text);
w.setValue("CARDDATA", txtCardData.Text);
w.setValue("CARDEXPIRYDATE", mm.SelectedValue + yy.SelectedValue);
w.setValue("CVC2", cvc2.Text);
w.setValue("TOTALAMOUNT", amount.Text);
w.setValue("CLIENTREF", "" + randObj.Next());
//Store the Webpay Object in the session. So it can be retrieved easily by other pages (results/errors, etc)
Session.Contents["WEBPAYOBJECT"] = w;
System.Exception ex = null;
for (int i = 0; i < 2; i++)
{
try
{
w.execute();
ex = null;
break;
}
catch (webpay.client.ConnectException cex)
{
//Log the error, and try again.
ex = cex;
continue;
}
catch (System.Exception ioex)
{
//If a TXNREFERENCE is available, check the status of the transaction.
//The number of times to loop, and the sleep time may vary depending on the
//requirements of your application.
ex = ioex;
w.setValue("TRANSACTIONTYPE", "STATUS");
for (int j = 0; j < 2; j++)
{
try
{
//In case we the connection was dropped part way thru,
//give the transacton time to complete at the back end
System.Threading.Thread.Sleep(1500);
}
catch (Exception e)
{
}
try
{
w.execute();
//If the responsecode is still "IP", then wait and check the status again.
if (w.getValue("RESPONSECODE") != "IP")
{
//We have a result, continue
break;
}
}
catch (System.Exception e)
{
ex = e;
}
}
}
}
if (ex != null)
{
//An exception was encounteded which could not be recovered, possibly
//while attempting to retry or check status. Set the redirect to a
//page/process which can handle error conditions.
Session.Contents["ERROR"] = ex;
return "ErrorPage.aspx";
}
//Processing completed normally - redirect and display the results to the user.
//NOTE: Your applicaton will need also need to inspect the RESPONSECODE parameter and
//store the transaction result somewhere. This should be done here, and not in the
//Result display code, as this code will only execute once, while the display code has the potential
//to be re-executed if the user clicks "Refresh" or attempts to re-process the transaction
//using the "Back" button.
return "ResultsPage.aspx";
}
}
// if you face any problem please feel free to ask
