Question

I am using the webbrowser control in C# for our desktop application to run a credit card through a gateway.

Simply, I’m loading the page on the load of the form:

public Form1()
{
  InitializeComponent();

  webBrowser1.Url = new Uri("https://paymentgateway.com/hosted.aspx?" +
                            "Username=dddd" +
                            "&Password=dddd" +
                            "&MerchantKey=5159" +
                            "&BillingAddress1=123 some street" +
                            "&BillingCity=Somewhere" +
                            "&BillingState=SC" +
                            "&BillingZip=39399" +
                            "&CustomerName=me" +
                            "&Amount=392.00" +
                            "&InvNum=123567" +
                            "&AccountNumber=0133333" +
                            "&CustomerId=0199999");


}

The page looks something like this:

My question is, how do I grab the response once the Process button has been clicked and then close out the form? I need to know if it was approved and the rest of the information from that point.

I don’t have control over the button so I’m not sure how to capture the response.

Thanks again!

Answer 1

It seems that you need to subscribe to the DocumentCompleted event and handle the response there via Document, DocumentText or DocumentStream.

You would then react appropriately depending on what the output is. For example:

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
  HtmlDocument document =  webBrowser1.Document;
  //now use any of the methods exposed by HtmlDocument to parse the output
}
