== This happened ==
Every time Firefox opened
== I updated to one of the firefox versions (Not sure which one it was)

Thanks Alex, but sadly I already tried that. Neither .docx or .xlsx files show up in the content list. They both show as a Chrome HTML document so changing how Firefox addresses those doesn't help since it thinks its the same type of file. I don't think I can manually add files into the "Content Type" left side nav.

You can copy the contents and paste it into a Word file. Just don't expect everything to transfer or to retain all of the formatting.

Write the file types in pattern Input string, separated by a semicolon ;
For example: *.vi;*.doc;*.jpeg;*.xls

Screen shots - how do I change the default file type

Screen shots using command, shift, 4: I used to get pdf files from the screen shot command, now I get PNG files. How do I change the default file type from PNG to PDF? PNGs are a pain.

Also, there are utilities like OnyX that will change the screenshot settings.
But this AppleScript is my favorite.

How to prepare Java Card Assembly files

Hi,
If we rebuilt the API's in Java Card then how could be Java card Assembly files be generated
thanks
murali

Thank you Lee and paulcw. Good to know that
information and thank you for your suggestion as
well. Like what paulcw mentioned, not to put
sensitive information in my code. I wrote those
because I need to connect to MS SQL. I just have no
idea how to connect to the database without writing
those codes in the file. Could anyone explain little
bit more on it? Thank you.Create a password file that is accessed by your program. It keeps the passwords out of the developers' hands. (Mandatory practice implemented by our DBAs).

How to add support for new file type.

Using the ESDK, I would like to add support for new file type ( a new extension). this new extension will function like any other non visual code editor but will have specific syntax highlighting, code folding and explorer.
I am trying ot figure out if I need to create a new editor or use existing JDeveloper code editor and add support for new file type. Does anyone have a high level outline on how to do this using the ESDK that is specifically targeted at adding new file type support for a text based code editor?
I have looked at the Samples and keep going in multipe directions. It would be cool if there was an example that was how add syntax higlighting for new file type.
Thank you

Brian, thank you. I looked at this extension and it answered a lot of questions for me. I was going in the right direction but needed a little help and bost of confidence, this is just what I needed. I created the LanguageSupport, LanguageModel, Addin, Node and TextDocument that are specific to the new file type. I was getting hung up on how to hook this into the JDevelpoer editor. I keep thinking I have to create a custom editor but it looks like I don't have to and it looks like I can associate this file support with the editor framwork, for version 10.1.3.2, with the following in the Addin Initilize() method.
Recognizer.mapExtensionToClass(MY_EXTENSION, MyNode.class);
CodeEditor.registerNodeType(MyNode.class, MY_EXTENSION);
LanguageModule.registerModuleForFileType(new MyLanguageModule(), MY_EXTENSION);
I have done this but still not able to recognize the new file type.
At this point, I just want to be able to recognize the new file and display it's associated icon or display a messare to the message log. I put a System.out.println("test") in the Initilize() method of my addin. then I registered MyAddin in the extension.xml. JDeveloper sees this new extension and it is loaded but I have not been able to show the test message or display the new icon when I open the new file type.

My download was an unknown file type and cannot be opened

my download was an unknown file type and cannot be opened

Sounds like the file extension was dropped when you saved your converted document. Make sure that the .docx (Word) or .xlsx (Excel) extension appears after your file name when saving your document.
You should be able to rename the document you already converted by adding the appropriate extension. The file should then open as expected.
Let us know how it goes!

Dreamweaver setting wrong file type and creator codes

First of all, I'm running Mac OS X 10.5.2 on an Intel-based
Mac, with Dreamweaver CS3 9.0 build 3481.
I have a site defined where I connect to my web server via
FTP. On my server, I just upgraded my forum software to PHPBB 3.0,
which created a new /forums/ directory. My plan is to use
Dreamweaver to download that new /forums/ directory to my local
site where I can edit the files. Inside the forums folder are
several types of files, like ".php" files, ".htm" files, ".gif"
files, etc.
So, upon downloading the /forums/ folder to my local machine
by dragging and dropping it (in Dreamweaver) from the remote site
to the local site, I noticed that Dreamweaver insists on setting
HFS file type and creator codes for files it recognizes, based on
the filename extension.
I've connected to the same server using the Finder and
Transmit, and copied the remote /forums/ folder over to my local
machine. Neither of those copies have files with file types and
creator codes set, meaning they aren't actually set on the remote
files and that this is indeed something Dreamweaver is doing on the
fly as it downloads the files.
I'm wondering if there's any way possible to disable this
behavior, and just download the files like they are on the server?
(File extension only). To make matters worse, on my Intel-based
Mac, it's not even setting the proper codes, as you can see in the
following image:
http://homepage.mac.com/mdouma46/images/dreamweaver.png
Notice for the ".php" document, it's attempting to set a file
type of 'TEXT' and a creator code of 'DmWr' (DreamWeaver's creator
code), but because the Dreamweaver developers didn't bother to take
into account the byte-ordering differences between PowerPC Macs and
Intel Macs, the codes are written in reverse: 'TEXT' becomes
'TXET', and 'DmWr' becomes 'rWmD'. (If you're going to use
low-level routines such as FSSetCatalogInfo() to set the file types
and creator codes, you need to call CFSwapInt32HostToBig() on the
OSType values before doing so, to make sure they're in Big-endian
format).
Anyone know where the conversion information is stored?
Thanks in advance.....

Creator codes are totally deprecated in snow leopard. as for a workaround you can use something like this.
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #ADD8E6;
overflow: auto;"
title="this text can be pasted into the Script Editor">
on open these_items
repeat with this_item in these_items
tell application "Finder"
set the_file to POSIX path of (this_item as alias)
tell application "System Events"
set default application of file (the_file) to ("Main HD:Applications:Preview.app" as alias)
end tell
end tell
end repeat
end open</pre>
save it as an application and drop files onto it to set them to open with Preview.

A "file type" question: using Terminal?

Hi all, how do I change the file type of files (as seen in the Get Info box?) Here's an odd thing. Apple's Logic Pro's been stable for a while now for me. Then I install Final Cut Studio as an upgrade from my Soundtrack Pro. Seems to crash a bit now....my Sampletank 2.1 plug-in (audio unit/component) which has been super fine seems to appear in Crashed thread zero, but I must add, I also installed the recent Pro Applications Update (and 10.4.7) too...
Oddest thing is that since installing Final Cut Studio, most of my Audio Unit plug-ins have had their "file type" which USED to be "Audio Unit/Component" changed to "iDVD2 file" AND, whereas before they'd all say "open with <none>", as they should do, those affected say now "open with DVD Studio Pro 2". Anyone know how to change them back to <none> (guess it involves using the Terminal...) or whether I need to????????? Nobody in the Logic thread as responded....

Hi, Chris.
That the specific file types are not being recognized correctly may indicate that the Launch Services database is corrupted.
See my "Resetting Launch Services" FAQ.
Good luck!

How do I upload an XML file to salesforce using BULK API?

Hi There,
Please let me know how do we upload an XML file to salesforce using Bulk API?
Thanks,
ET

Hi,
I think that this is a more SalesForce.com question and think you will have more chance looking at SOAP API Developer's Guide for salesforce. Sending a SOAP request from the API Server is very straight forward and there are several tutorials and well documented about this.
Cheers,
Stefan

I can not get any updates and therefor not use Java as it only run updates for Mac 10.7. and later? How do i get the updates to install and use Java?

I can not get ny updates and therefore not use Java, as it only run updates for MAC 10.7. and later. How do i get the updates to install and use JAVA ?

In Snow Leopard you update Java from Software Update (in the Apple menu). You can check your version by opening Terminal and typing
java -version
(don't get creative and type anything else)
The latest version is 1.6.0_65.
