Security Exception

**RFH Reseller: spire128** · 8th February 2007, 01:43 AM

Hi All

I have a problem with this line of code
Dim req As HttpWebRequest = CType(WebRequest.Create(PayPal_Url), HttpWebRequest)

The variable PayPal_Url is what it say's for using the Pay Pal std payments, but I get a security exception when I try and run this line of code in a Medium trust environment, so can anyone tell me how to re write please.

have you tried...

Code:

 
Dim request As WebRequest = WebRequest.Create(PayPal_Url)
request.Method = "POST"

Hi

Thanks for that but it did not work this bit throws an security exception,

WebRequest.Create(PayPal_Url)

I know it's to do with Medium Trust Environment, but don't know how to code arround it, or even if it's possible

Anyone else any ideas?
