A potentially dangerous Request.Form value was detected from the client (number="12 <!DOCTYPE HTML PUBLI...").

i am trying to send the variable number = 12 to flash

this is what i have

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Response.Write("&number=12")

End Sub

This is caused by the ValidateRequest attribute of the Page directive. By default it is set to true, which means that ASP.NET
examines all input for potentially dangerous data.

If you set the ValidateRequest to false in your web.config, machine.config or Page directive of your particular page, it should work.

----------------------------------------------

<system.web>
<pages validateRequest="false" />
</system.web>

----------------------------------------------
//Your Page
<%@ Page language="c#" Codebehind="brandAdd.aspx.cs" AutoEventWireup="false" Inherits="Admin.brandAdd" ValidateRequest="false %>
----------------------------------------------

I'm a bit surprised that my answer was accepted so easily, as it rather lacked substance. Of course, it's probably just that what I said was all the clue you needed to track down the bug. Still, if you need additional help, feel free to just say so. For 500 question points, I think you're entitled to a bit more help than what I gave, and I'm happy to give more of a hand (and more points really aren't necessary).
