To set personalization in a Web program, fault tolerant Prompt window

Web| Program | Fault tolerance first design a fault-tolerant hint of the window image as follows:



The key HTML text is as follows:

"Reason: <%=content[int32.parse (request.querystring[" MS "])]%>"

Then add the following in the Code editing window:

public class WebForm1:System.Web.UI.Page
{
Public string[] content;
private void Page_Load (object sender, System.EventArgs e)
{
Content=new STRING[10];
content[1]= ". Hint 1.";
content[2]= "Hint 2";
... ...

}

===========================================

This is called in a fault-tolerant Web page:

[/* Below is an example!) */]

public void Check ()
{//Check the legality of user input;
Detects if the order number [type] is blank;
if (lOrderName.InnerText.Trim () = = "" | | LOrderCategory.InnerText.Trim () = = "")
{
Response.Redirect (@ "...) \exceptions.aspx?ms=11 ");
}
Determine whether the number of users input is correct;
Try
{
int i = convert.toint16 (Tbquantity.text);
if (i ==0)
{
Response.Redirect (@ "...) \exceptions.aspx?ms=12 ");
}
}
Catch
{
Response.Redirect (@ "...) \exceptions.aspx?ms=12 ");
}
Determine whether the date is correct;
Try
{
Convert.todatetime (Tbterm.text);
}
Catch
{
Response.Redirect (@ "...) \exceptions.aspx?ms=9 ");
}
To determine the delivery time must be greater than the opening date;
if (Convert.todatetime (Tbterm.text) < Convert.todatetime (request.cookies["order"). values["Date"])
{
Response.Redirect (@ "...) \exceptions.aspx?ms=14 ");
}
Determine if the current model already exists in the current order;
DataClass dc = new DataClass ();
if (DC. Checkmodel (Lordername.innertext,lbmodel.selectedvalue.tostring ()))
{
Response.Redirect (@ "...) \exceptions.aspx?ms=13 ");
}
When the order type is: "S-p", the detection can not exceed the limit;
if (lordercategory.innertext== "S-p")
{
if (Convert.ToInt32 (Tbquantity.text) > Convert.ToInt32 (lbupper.innertext))
{
Response.Redirect (@ "...) \exceptions.aspx?ms=18 ");
}
}
}

==========================================

Where exceptions.aspx is the fault-tolerant window we just defined!
