I've been using Classic ASP for some time, and up to now I've been fairly good, but I've hit a problem.

In chapter 4, Arithmetic Calculations, the figures are based on an integer, but how to convert this to use with a string.

In need to multiply <%=MonthlyCost%> by 2 as the client pays 2 months in advance.

Could the example in the book for a tax calculation be used?

There are various ways to convert data types in the .NET framework, but if you are coding with VB.NET (not C#) then you can use the same functions you have used all along with VBScript:
   CINT( )
   CDBL( )
   CCURR( )
   CSTR( )
   and so on.

The only difference is that whereas CINT() in VBScript only handled 16 bit numbers (and so was limited to the range -32768 to 32767), CINT() in VB.NET handles full 32 bit number (+/- 2 billion). And CLNG() in VB.NET handles 64 bit numbers. All the other Cxxxx functions remain the same.

So, if MonthlyCost is a string, you should be able to do
    <%=2 * CCurr(MonthlyCost)%>
or
    <%=2 * CDbl(MonthlyCost)%>

The whole site has been done using ASP, so to switch to VBScript will cause the missmatch error to come up.

Hi Guys

Managed to solve this little problem, and leave some hair in place.

The systems starts with

<% if Request.Form("submit1") = "GET QUOTE NOW" then
        Session("Age") = intAge
        Session("Gender") = txtGender
        Session("NonSmoker") = bNonSmoker
        Session("LifeCover") = curPremium
        Session("MonthlyPremium") = lifeAss
        Response.Redirect "quotes201.asp"
    end if
%>

All I had to do was add a futher line "Session("SinglePremium") = lifeAss*2. The new session object is carried through the system.

Ummm...I hate to tell you this, but you *ARE* coding in VBScript. ASP is *NOT* a language; it's a framework. And you can code in ASP in VBScript or JScript or (if you can still find it) PerlScript. 96% or more of ASP is indeed done in VBScript.

And my answer was correct for VBScript. I misread the forum you posted in as being ASP.NET 3.0, but the answer I gave you works equally well in VBScript, honest.

Yes, you can simply multiply in VBS to force the conversion (to DOUBLE, by the way, if you care...same as using CDBL( ) that is).
