Hi there,

I am trying to call a C# web service from an aspx page, I have the asmx
file, a user control file ascx and the aspx file. I have verified that the
web service is returning correct values from the service, however when I try
to load the aspx page it falls over in a cruumbling heap! Could someone tell
me what I am doing wrong as I know that I am close to getting this thing
working.

Thanks in advance for your answer

try instantiating Service1 as below in Button1_Click(o bject sender,
System.EventArg s e) as below.

CurrencyNS.Serv ice1 currSvc = new CurrencyNS.Serv ice1();

Ur code will look some thing like...

private void Button1_Click(o bject sender, System.EventArg s e)
{
CurrencyNS.Serv ice1 currSvc = new CurrencyNS.Serv ice1();
double dRate = currSvc.Convers ionRate(currFro m.CurrencyCode,
currTo.Currency Code);
if (dRate < 0)
lblConversion.T ext = "Error Occured";
else
lblConversion.T ext = "" + txtAmount.Text + " " + currFrom.Curren cyCode
+
"(s) =" + Convert.ToStrin g(dRate * Convert.ToDoubl e(txtAmount.Tex t)) +

Hi there,

CurrencyNS.Serv ice1(); the program still give me an error. I have pasted the
code from the aspx page into the post, could you tell me if I am missing
something?
