Quick Question

[Thraxius]

This command does not work and I was wondering what I need to do to get the desired results:

pos = StringLastIndexOf(ChangerLoc, " ")

The problem is I need to parse the information in ChangerLoc at a <space>. What command do I need to use. I know for a file separator you can use this java_io_File_separator. Is there something like that for space?

Works for me when I try in Expression Evaluator. What's your evidence for thinking it doesn't work? Have you verified that ChangerLoc is a String and contains the text you think it contains?

Well this is what I have done. I did a ChangerLoc = GetElement(DVDLoc, 0). Now when I do a ChangerLoc with a Text under it. It returns the information I am looking for on screen. It shows me. Changer1 199

What I need to do is split that up so I can do some evaluation and manipulation of it. I need to turn Changer1 199 into "199 Changer 1" Problem is when I do pos = StringLastIndexOf(ChangerLoc, " ") Then do Location = Substring(ChangerLoc, 0, pos). I get nothing in the variable Location. Using tracer is not helping me either.

DVDLoc
ChangerLoc
Location
Slot

are all attributes that are created for the page.

OK, where does DVDLoc come from? Is it an array of Strings, or an array of something else that happens to be convertible to a String by the Text widget? The docs for StringLastIndexOf don't say anything about automatically converting non-Strings to Strings, so you should probably make sure what you're passing in really is a String (i.e. an instance of java.lang.String). You can find out by doing java_lang_Class_getName(java_lang_Object_getClass(ChangerLoc)). Use the DebugLog API to print out the result to the debug log.

Similarly, check the pos result from StringLastIndexOf to see if that's what you expect. Basically you just need to break your code down into minimal steps and examine the input and output of each step to find out exactly where it's going wrong.

Thanks for you help. DVDLoc is created from DVDPro2Sage.

It is an array from DVD Disc section.

[Changer1 188, Changer1 189, Changer1 190]

That would be the response that is passed into DVDLoc. I can retrieve the data out by doing a getElement. I will try to implement what you said to determine what that array is made of.

I just want this to over. I am not cut out for this work. My mind hurts.

Hello, after a good nights sleep I found what I needed. It was a simple typo. I had a lower case Of.
