substring and error - why?
in [VbScript]
|
From: mrkramer on 17 Apr 2010 09:17 Hello I'm newbie on vbs programing. I'm trying use subsstring method, but I get error "object required 'helo great world'" and code:800A01A08. ------- dim str str="helo great world" wscript.echo str.substring(5,10) --------------------- It is wierd for me because documentation says: strVariable.substring(start, end) "String Literal".substring(start, end) It is possible that substring method is only in Jscript?

The expression "str.substr(5,10)" implies that substr is a method of a object str. The variable str is not an object reference, but a string. All object references in VBScript are established with "Set" statements, as in: Set objShell = CreateObject("Wscript.Shell") There is no substring function in VBScript (that I am aware of). Your example looks more like .NET to me. I note that when I search for syntax examples I frequently find .NET examples. I don't know what documentation you found, but the example is definitely not VBScript. I believe the Mid function does what you intend. For example: str = "helo great world" Wscript.Echo Mid(str, 5, 10) This will echo the string "great worl". Or, since the third parameter of the Mid function is optional, you could try: Wscript.Echo Mid(str, 5) which would result in "great world".

There is substring method, but as I said previously, i'm afraid that is Jscript method only. Mid function is good and is similar to substring. I'll use mid function. Thanks for help

(Apparently they were spending too much on paper with multiple CHMs. :) Now you have to check at the top of the topic page to make sure you've got a VBScript topic. There is a file called vbscrip5.chm. I have a copy. You might do a search for that if you want to have a straight VBS reference.

I find the Mid function under VBScript functions (not methods) in the contents. -- Richard Mueller MVP Directory Services Hilltop Lab - http://www.rlmueller.net -- |
