IWeb and uploading jpegs with spaces in their names

I have created a site with about 100 jpegs that I wish to load up to a server other than ".Mac". Some jpegs have spaces in their names, so "Fetch" will not upload them. I deleted the spaces from their names and loaded the jpegs back into the site and saved and published to a folder. However, the resulting "Site"folder shows the jpegs still have spaces in their names, even though I removed them from the name of the jpeg. IWeb must be getting the name from some internal tag or something. For example, I had a jpeg called "Billie Holiday.jpg" I changed the name to "BillieH.jpg", but when I publish the site to a folder, the jpeg still shows up as "Billie Holiday.jpg" and therefore I cant upload it using "Fetch". Where is iWeb getting the names of the jpegs from, and how do I remove the spaces? Or, does anybody know of an application that can upload files (ftp) with spaces in their names?
Thanks,
Mitch

Very strange. You might try renaming the site with Inspector to something else than Site and republishing, to guarantee you have a totally new set of files.

It's not the ftp program. You can't have spaces in file names on most web servers, they won't accept the files.

Accessing objects with jstl

Hello forum,
A question about JSTL - one of the things I have not figured out until now. How can you access an object declared by a specialized tag? Generaly you c:set the variable you wish and you use EL to malipulate it. But how can you access a locale object or resource bundle object? Let's take the bundle object for example:
The code that would declare it would be:
<fmt:setLocale value="theLocale"/>
<fmt:bundle basename="thebasename"/>
Suppose that later in the code you want to access the created resource bundle object - how can you do that? Obviously a resource bundle object has been created, but how can you call one of its methods?
Thanks in advance,
Michael

"and I really I am not that willing to decide that I will revert them to JSTL, at least not if they are really long"
Well, right there is your problem. You will need to decide to do it, or not. You are experiencing one of the major problems of NOT using JSTL... when scriptlets get long they are difficult to maintain and change (which is why you shouldn't use them from the beginning.. but that is not pertinent to this topic).
The issue is that some JSTL and some custom Tags have their own means of working with objects without sharing those objects with the application (it preserves encapsulation.. they can only be sure something is kept correct if they handle it themselves and don't let others mess with it).
"This is a major problem for using jstl."
This isn't a problem with JSTL, it is a problem of combining JSTL with scriptlets. JSTL should be used as a replacement for scriplets, in my opinion, not alongside them. It makes it much easier to
1) plan what you are doing when coding
2) read the code and understand it later when maintaining.
So my advice would be to stick with one or the other (further I would suggest going all the way with JSTL, but the time of converting old scriptlet code is a negative that you will have to measure yourself...)

DI API - accessing objects with Read only permissions

Scenario: I have setup a user in B1 with "Read Only permissions" on the Business Partner. When I log into the DI API as this user and try instantiating the BP object, I get a message "Loged on user does not have permissions".
Why am I getting this? Shouldnt I be able to instantiate the object and read the property values. i understand that I cannot Add or Update because of read only permissions.
Is there a way we can retreive values for users using the DI API or should the best option be to write a SQL statement.
Thanks,
Gopal

Requiring the user to have full authorization to instantiate an object is a serious limitation for the DI API. It makes it virtually useless. After all it is supposed to be OOP and all the trimmings isnt it? It also takes a lot of control away from the user.

Hi,
I have confirmation from B1 product definition, the DI API access for objects with Read only permissions will not be included in the 2007A version. It will be considered for the following version after 2007A.
There is a chapter called "Authorization Checks" in the SDK Help file specifying:
"SAP Business One performs authorization checks for the business objects and the infrastructure and meta data objects. If a user does not have full authorization to access the objects in SAP Business One, the user will not have permission to access the data belonging to the business objects using the DI API."

Sort artists with numbers as their names first

Not to long ago, iTunes used to sort artists that had numbers in their names (311, 2pac, 50 cent)
first on the list, which i loved because numbers should always come before letters, but in the recent updates with itunes, numbers are now last after the Z's
Can someone give me a solution for this? a registry key or something maybe?

I did a litle cheat. I have some artists that I WANT to list at the top and before I did the
1. [artist name]
2. [artist2 name]
But since they decided to list these at the bottom (stupid decision), I mass updated the info on each artist to start with a.1, a.2, a.3, etc. This now lists the artists at the top in the order I want them in. A very nice easy workaround. No telling what Apple will do down the road, it's obvious they think #'s should be after letters. Contrarian company, I swear.

MS Access DB with Spaces in Column Name

Good Afternoon-
I'm having some serious headaches with a table that I need to extract information from. The powers that be wrote it with the following column names "Contract Number" , "Customer Number", "Description".
Note the spaces in the columns.
Sample code from here: http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=2691&lngWId=2
I'm using sample code for connecting to the database and I can access everything using the select statements, except if the column contains a space. I get the following errors:
s.execute("select [Customer Number], Name from Customer");
Error: java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1.
s.execute("select \"Customer Number\", Name from Customer");
Error: java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1.
s.execute("select Customer*Number, Name from Customer");
Error: java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 2.
s.execute("select 'Customer Number' , Name from Customer");
Data from column_name: Customer Number , Unknown
This works, but would require parsing-
s.execute("select * from Customer");
Data from column_name: 5 , Unknown
Suggestions would be truly appreciated.
Jason

"select [Customer Number] , Name from Customer " ;
returned the correct responses.Double quoted identifiers, which is part of ANSI SQL should have solved it....
"select \"Customer Number\" , Name from Customer " ;
As mentioned above it has certainly been my experience that DBAs (those with that title) all insist that quoted identifiers should never be used. Thus refactoring the database identifiers is actually the correct solution.

Access FTP with whitespaces in dir names

Hi,
I'm trying to make a recursive list of files in an FTP directory.
While FileZilla deals with whitespaces in directory names with no problem, it seems that Labview struggles a bit.
Indeed, if I ask labview to get the files and directory of a folder named, for instance, /Projects/Camera 1/, it will return an empty array (while FileZilla clearly sees 12 files in this folder). It seems that the problem is the whitespace in the name because if I replace (using FileZilla) the space character with "_", LV correctly gives me the file list.
Any idea how to make the LabView FTP function correctly deal with whitespaces in directory and file names?
Best regards,
perper2001

FYI, it works OK with the MLSD function.
That is very possible. I haven't checked the FTP RFC in a while. Most likely they added those new commands to accomodate these new things explicitedly. Doesn't have to mean that an FTP server couldn't support quoted paths with the standard commands, but that is a feature of your FTP server, not of the client you use to talk to the server. So LabVIEW can't do anything about this here. It is mainly a feature that your FTP server has to provide and there might be differences between different FTP servers.

Mplayer can't play files with spaces in their name

After scratching my head and reinstalling codecs several times without luck, and old memory resurfaced of this occuring before and I managed to solve the problem.
The thing is that if you doubleclick a file in Nautilus, and said files has spaces in its name, mplayer won't be able to play it, and gives a very cryptic error message, ie "cannot play file a%20b.avi" if the name of the file is "a b.avi".
The trick is mentioned in this thread -- you edit /usr/share/applications/mplayer.desktop and change 'Exec=gmplayer %U' to 'Exec=gmplayer %F'.
The bug has been around forever, and hasn't been fixed yet. Perhaps the mplayer devs don't want to fix it. In any case, I would propose that either we fix this in the mplayer Arch package, or that someone more knowledgeable than I get in touch with the devs about it.
Just a suggestion, but I think it's kind of important. It's really confusing to new users.

In my opinion, it it's not arch's job to fix bugs from upstream, no matter if it's mplayer or gnome's fault. Of course there are exceptions, eg if a bug in a critical package hardlocks the whole system, or adds a huge security risk.
I would like to belive that the general arch user is smart enough to find one of the 30 threads about this bug (or the entry on the bugtracker) and fix it themselves. Personaly I would put this in the same category as packages that don't have a .desktop file at all from upstream.
Oh, and as a small sidenote: http://phraktured.net/patching-patching-patching.html

Alphabetical Artist listing of artists with 'The' in their name

Previously my nano would ignore the 'the' in artist names such as 'The Used' and 'The Hush Sound', ordering them by the second word. However, when I started using my ipod today, it no longer ignores the 'The' and has collected all artists whose names start with 'The' in 'T'.
Is there a way to change this so the ipod ignores the 'The' in artist names like it used to only a few days ago (and like most alphabetised systems do)?

im trying to search my settings.... mine is sorting the way it should be excluding 'the' from the titles when sorting...

Accessing Informix tables that have their names in lower case from BW

Can anyone please help with this?
Has anyone done it using views?
Thanks

Hi Frank,
I assume you are talking about using DB Connect functionality. If this is the case, the usual workaround is to create a view on the table and have all the fields and the view name in upper case. BI would then read the meta data from the view and be able to issue select statements.
This restrictions is not in place if you use UDI functionality as the drivers can use mixed case.
I hope this helps,
Mike.

How to burn disc with period (.) in name? Finder says ".fpbf" extension req

I'm trying to burn a disc with the date in the name, like "mydisc 2006.10.31" but the finder says "you cannot remove or change the extension .fpbf because it is required by the finder."
What is this supposed to mean? I don't want a disc with that extension. In 10.39 burning a disc with this name was not an issue. If I then burn the disc and try to put the name in the window asking me the disk speed, then the disc burns but shows up as "mydisc 2006.10". It also appears that adding the ".fpbf" extension to the disc name, when in the finder, makes the disc show up normally before it is burned, but still burns without the last digits. Have not tried renaming just before burn confirmation yet.

It appears that adding ".fpbf" in the dialog when you confirm the disc name and burn speed, such as "mydisc 2006.10.31.fpbf" will then burn the disc correctly with the name as "mydisc 2006.10.31".
An ungainly but functional workaround. The disc name also then appears correct in OS9, so its not just a 'Finder trick' after its burned, the disc name is actually correct.

Can't access object using "id" or "name" if created with actionscript

How can you register an instance of an object with actionscript so that it's id or name value is accessible?
I included a simple example where a Button is created using mxml and in the same way it is created using actionscript. The actionscript object is inaccessible using it's "id" and "name" property.
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

               creationComplete="application1_creationCompleteHandler(event)">
    <fx:Script>
        <![CDATA[
            import mx.events.FlexEvent;
            protected function application1_creationCompleteHandler(event:FlexEvent):void
                import spark.components.Button;
                var asBtn:Button = new Button();
                asBtn.label = "actionscript";
                asBtn.x = 200;
                asBtn.id = "asButton";
                asBtn.name = "asButtonName";
                addElement(asBtn);
                trace("mxmlButton="+this["mxmlButton"].label); // returns: mxml label
                //trace("mxmlButton="+this["asButton"].label); // returns runtime error: ReferenceError: Error #1069: Property asButton not found on TestId and there is no default value.
                //trace("mxmlButton="+this["asButtonName"].label); // returns runtime error: ReferenceError: Error #1069: Property asButtonName not found on TestId and there is no default value.
        ]]>
    </fx:Script>
    <s:Button
        id="mxmlButton"
        label="mxml label"
        alpha="0.8"/>
</s:Application>

Hi Dan,
It is a very rare occurrence when I miss not being able to access an object (object property, really) using the ["name"] notation for objects created using actionscript.
In MXML the compiler is conveniently adding an attribute to the class with the same name as the id, so you can conveniently refer to it using the [] notation. While we explicitly specify an application container to use, the MXML compiler creates a custom container which is a derivative of the base container and to that it adds properties for the children declared in MXML. I guess it also effectively calls "addElement" for us when the container is being constructed.
Your example assumes that using "addElement" to add the button to the application container is the same as declaring a variable (ie property ). It isn't, so there's no point in looking for an property of the name "as3Button" using the [] notation, because it doesn't exist. The container is managing a collection of children in it's display list and that's not the same as being accessible as properties of the container.
Generally speaking, accessing properties using the ["name"] syntax isn't necessary.
Paul
[edit: you may wonder why "addElement" doesn't conveniently also add the "id" attribute to be an property of the container class. Unfortunately, it can't because the container class would need to be dynamic and it's not. A further complication would be that adding properties at runtime would invite naming clashes at runtime with associated mayhem. MXML can do this because the compiler generates the class and can trap name duplication at compile time.
Great question, BTW.
-last edit changed my "attributes" to be "properties" in line with Adobe's terminology]

Can I move files frm 9.2 to Tiger with 1-3 periods in their filenames?

I need to move big collection of images & design files that have 1-3 periods in their file names.
Can I move them from my G4 (9.2) to my Intel iMac (10.4.9) without creating problems? I mostly use Quark, Adobe/Photoshop CS3, Acrobat & Preview (but no iPhoto, iLife, iSync, etc.), and archive my images in subject folders. I WAS opening the G4 folders & deleting periods and slashes manually - but UGH - I am burnt out. I've read conflicting info on the forums. Some say NEVER. Some say Yes. Some say only if it's OSX to OSX - - not 9.2 to OSX. I'm trying to do this right, to avoid problems down the line. Can someone help with this? Thank you.
iMac Intel 24" desktop. Mac G4 Mac OS X (10.4.9)
iMac Intel 24" desktop. Mac G4 laptop Mac OS X (10.4.9)

I have used lots of files with /s and multiple periods, with no problems. Some Unix based applications may not like the /, but the file-system doesn't mind it.
From Help in the Finder:
"You cannot use a colon (:) in the name of files and folders. Mac OS X uses this character to separate folders in pathnames.
In addition, some applications may not allow you to use slashes (/) or other characters in the names of items."
From
<http://developer.apple.com/documentation/Darwin/Reference/ManPages/mann/filenam e.ntcl.html>
"The normal Mac style names use colons as path separators. Paths may be relative or absolute, and file names may contain any character other than colon."

Development Objects with " / " names

Hi ABAP experts,
Have you ever come across ABAP custom objects with "/" names, such as /BPPwhatever
I'm wondering if developers can use such names for custom objects instead og "usual" Z_ or Y_
Thanks,

This is a namespace.
Developer organisations (SAP, customers, Partners, ISVs, etc.) can register their own namespace with SAP.
Then they can create their own objects inside this namespace without worrying about nameing conflict with others.
E.g IBM might register the namespace "IBM". Then they can create objects such as /IBM/PROGRAM1, /IBM/DBTAB1, etc.
If they created objects in the "customer namespace" (i.e. starting with "Z" or "Y") someone else could create an object of the same name in another development system and when the two development streams were consolidated there would be a conflict. Namespaces prevent this from happening.
Cheers
Graham Robbo
