Convert string to int in vbscript?

Hey edwilli, i tried doing cInt(fromDate) and i tried cInt(fromMonth), cInt(fromDay), cInt(fromYear) but it gives me a type mismatch error...

what does datepart do?

fromDate is a string by the way... can u use Datepart with a string?

Why not do
dateFrom=cdate(request("datefrom")
Then you can compare the dates as dates.

oopsss... forget a paren
dateFrom=cdate(request("datefrom"))

If i wasnt working with dates...

say it was a number as a string.. how do i turn it into an integer? I tried searching everywhere on the web but i could not find it.

try using one of the following :


int.Parse("1234");

or


Convert.ToInt32("1234");

yea i tried that... this is no asp.net .. its the older version

<SCRIPT LANGUAGE=JAVASCRIPT>
<!--
var myinteger = 123;
var mystring = myinterger + '';
//-->
</SCRIPT>

is this ok ?

If it's a number, you shouldn't need to convert it. But if you want to make sure it's an integer, use cint("variable")

silentScope,

try this test page... assuming that you entered a correct date with your format... it is already a number why do you need to use the cint... without still roduce the sam output...

===save this as test8.asp

<%
if request.form("Submit") = "Submit" then
fromDate = Request("datefrom")
         fromMonth = Left(fromDate,2)
         fromDay =  Right(Left(fromDate,5),2)
         fromYear =  Right(fromDate,2)

if fromMonth < 12 then

response.write "true"

else

response.write "false"

end if

response.write      fromDay
response.write      fromYear

end if
           %>
           
           <form name="form1" method="post" action="test8.asp">
           <input type="text" name="datefrom">
           <input type="submit" name="Submit" value="Submit">
</form>


HTH..

HAppy programming...

Make sure if you're using CInt(strVar) or CLng(strVar) that you use  if IsNumeric(strVar) as a check before the conversion.

silentScope,

try to replace the asp of my previous post with this...
it first check the date if valid or not.


<%
if request.form("Submit") = "Submit" then


fromDate = Request("datefrom")

if IsDate(tmpmydate) = "True" then

        fromMonth = Left(fromDate,2)
        fromDay =  Right(Left(fromDate,5),2)
        fromYear =  Right(fromDate,2)

if fromMonth < 12 then

response.write "true"

else

response.write "false"

end if

response.write      fromDay
response.write      fromYear

else


response.write "Kindly input a valid date..."

end if

end if
          %>
         

HTH...

Happy programming...

I appreciate all the comments,  but im so confused.

When i do the fromMonth        

fromMonth = Left(fromDate,2)
fromDay =  Right(Left(fromDate,5),2)
fromYear =  Right(fromDate,2)

fromDate is a string that the user enters in, a date.

So fromMonth and fromDay and fromYear are all strings right? I'm curious how you turn them into integers.

In javascript, i did this:

var toDate = document.orderform.dateto.value;
var month = parseInt(toDate.substring(0,2));
var date = parseInt(toDate.substring(3,5));
var year = parseInt(toDate.substring(6,8));

Now im curious how you do something like that in vbscript?

You don't need to. Do this instead

dateFrom=cdate(request("datefrom")
fromMonth=month("dateFrom")
fromYear=year("dateFrom")
fromDay=day("dateFrom")

But if you would show us how you're comparing the dates, we can probably help you do that. It's better to compare the dates as dates, rather than go through all the breaking it down to do a comparison.

everything works great now, im just curious how you convert a string with a number ie "5" into an integer to use to compare. Pretend im not playing with dates anymore.

'In VBScript, as you know, all variables are type variant,
'but we can use the following functions to specify the
'sub-type of a variable:
'CBool  - Variant of subtype Boolean
'CByte  - Variant of subtype Byte
'CCur   - Variant of subtype Currency
'CDate  - Variant of subtype Date
'CDbl   - Variant of subtype Double
'CInt   - Variant of subtype Integer
'CLng   - Variant of subtype Long
'CSng   - Variant of subtype Single

Dim strValue
Dim intValue
strValue = "24" 'Request.Form("Amount")

'You can double-check that the string contains a valid number
If IsNumeric(strValue) Then
     'Make intValue a variant of sub-type integer
     intValue = CInt(strValue)
End If

'Also, you can check the subtype of a variant using the TypeName function
MyType = TypeName(strValue)   ' Returns "String".
MyType = TypeName(intValue)   ' Returns "Integer".
