VBScript: Converting string to a number

I have a number in string format that my VBScript won't treat as a number.

For example:


myVar = "100"
If mVar >= 100 then
:
:




I get an error on the "If" line. I program in C++ all the time so I completely understand the difference between "100" and 100, but what I don't understand is when this bizarre VBScript and its VARIANT datatype will do this or that for me.

So, my simple question is how do I convert this into a number? I checked the MSDN and I swear that Microsoft couldn't design a more difficult documentation package than the MSDN if they tried!

Try:

Somevar = "100"

if CInt(somevar) <= 100 then
....

Doesn't work. I get:


Microsoft VBScript runtime error '800a000d'

Type mismatch: 'CInt'

/myfile.asp, line 29

I tried the following code and it works fine

dim a
a= "100"
if a>90 then msgbox "greater"

check theat you have the write version of Internet Explorer. I believe it must work with IE 5 +

I think the server might still be a IE 4 system. What is the solution if I have such an old server?

First solution is to upgrade (it is free)
Second - in VBS all the variables are variant. There are no strings or numbers. Try to enter you var
instead a ="100"
try a = 100

I am not sure, but it might help

Try with this


<%


dim myString

myString = "100"

if Cint(myString) <= 100 then
...........
else
...........
end if

%>

its working, try this also CLng,CDbl,CSng

Thanks for the replay, but for some reason I get scripting errors with the function CInt. From someone else's comment, I think my problem has to do with using an old 4.X version of Internet Explorer.

You may use

dim myString

myString=""

if Cint(myString) < 100 then
...........
else
...........
end if

then you get scripting errors with the function CInt.

now try this one

if Cint( "0"&myString) < 100 then
...........
else
...........
end if


This works. I tested it.

I would think after 16 years the problem has either been solved or forgotten ;)
