Another darn Error 13 posting

[ Edited ]

I have ready every single posting here with the term Error 13. Happy I was testing my AIM solution and it was awesome. Then my client learns that the price of a PCI compliant server is ten times what he has been paying so here we go. My SIM solution is simple and should work but I have not gotten past the Error 13.  I even tried using the sample code pasted right into my app. The param_dump.asp page shows no aberations unless it is the hash, which I cannot be sure is correct but since I am using the exact same sample HMAC_MD5 method, it should be good.

 

I've also copied the address https://test.authorize.net/gateway/transact.dll and pasted it directly into my code.

 

I have verified my API Login and Transaction Key.  Also I set a new key in the merchant interface and tried that key (three times I changed these).

 

Embarrassed I won't tell you how many hours I have into this one problem but secretly I will be happy if you or I find some stupid mistake I am making.

Re: Another darn Error 13 posting

It getting Error 13 because it can't find the loginID because it's doesn't work inside a master page.

This will work

<input name="x_login" type="hidden" id="x_login" value="76zggAY2M" />


This will not work.
<input name="ctl00$ContentPlaceHolder1$x_login" type="hidden" id="ctl00_ContentPlaceHolder1_x_login" value="76zggAY2M" />

Whoops, of-course.  I can work with that.  Thanks for your patient answer.

Re: Another darn Error 13 posting

The way to handle this in ASP.NET Master Pages is to override Render and replace the Ctl00$...$.

 

    Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
        Dim Html As New StringWriter()
        Dim Render As New HtmlTextWriter(Html)
        MyBase.Render(Render)
        writer.Write(Html.ToString().Replace("name=""ctl00$MainContent$", "name=""").Replace("id=""ctl00_MainContent_", "id="""))
    End Sub
