I'm retrieving a list of File objects and want to manipulate the file name. However, whenever I try to do any String manipulations with myFile.Name, I get a VBScript error that it isn't a String object. So that lead me to start looking at Strings and getting absolutely nowhere.
For example, Mathcad won't let me do any of the following:
1. Set str = New String("foo") (All of these generates an "expected end of statement" error. Huh?)
Dim str = String("foo")
Dim str = new String("foo")
2. str = "foobar"
index = str.lastIndexOf("foo") (Complains "object required", which I presume means it doesn't think str is a String object.)
3. str = "foobar"
index = LastIndexOf(str, "foo") (Error is "type mismatch")
This is driving me nuts! How do I create a String object, especially from the file.Name method?
Errors are:
1. "String" don't exist as an object (actually the word is a function), are a data type. So you can assign with Set or New. The error "expected end of statement" is because can't use Dim with assignation in vbscript.
2 & 3. "foo" isn't an object nor str.
I think that what you want is the funciton Len(str) which return the string length.
VBScript is a very small subset of the basic language. You can try to find in your computer the file "script56.chm" or try in microsoft web to download it.

VBScript or JScript? You can write a scripted component in either, bt not a mixture of the two.
The code you have in 2 and 3 is JScript. In VB a string is a variable subtype, not an object.
I have many examples of how to do this kind of stuff. What exactly are you trying to do?
OK, I eventually found what I was looking for thanks to the link to the script56.chm.
As pointed out, VBScript doesn't handle strings as proper String objects. (Obviously, VBScript was written a long time ago!)
So, to manipulate the file name (obtained from a proper File object), I must do this:
Dim myString
myString = myFileObject.Name
Then I can use various string functions that exist separately, such as
myIndex = InStr(myString, "*.txt")
to get the index of the *.txt suffix.
Yes, VBscript is a little old.
If you tell me what you are trying to achieve though, I may have something already written that could save you a lot of work.
Thanks, but I've got it done. Once I realized I had to use the various functions that work on string-like variables, it was easy.
