ANSWER: HOW TO DETECT Java Plugin from JavaScript

I created a new topic because the questions about
how to detect Java Plugin in browsers are scattered
thoughout this forum.
Basically you need to employ two approaches for IE and NS.
In IE you need to try to instantiate a small applet
(not your production applet) in order to see if browser
can do it. if the browser can do it, you can make a
call applet from JavaScript in order to find version of
JRE (as well as a host of other things).
In NS you can write a simple JavaScript which will
interrogate the browser for all plugins installed. Then
ypu can make a desicion whether to pass execution to
the next(or generated) page which hosts your applet,
or ask the user to download/install a plugin.
I ecourage everybody to host a plugin on your site
rather leave default link to it which is generated by
html converter.
In order to run sample,
Prerequisites:
Java Plugin 1.3.
If you have a different version of plugin,
substitute hardcoded plugin version in JavaScript for
value that you have.
1. compile java file
2. put class file in the same directory with html file
3. load html file into the browser.
4. press "Check Java Plugin.." button
5. see it work
6. examine code
7. uninstall plugin
8. repeat steps 1 - 4
9. see it work
10. install plugin.
Sample code follows:
**********************HTML FILE BEGIN***********
<HTML>

Try following java script, it works on new browsers (NS 4+, IE5+). For IE you have to enable 'ActiveX objects creation' in security options.

How do I set Page Width to Multiple Pages?

How do I set Page Width to Multiple Pages?
I notice when Cross Tabs are used, the report spans over several pages in width. Can I set this option without using a cross-tab? Since I am having trouble finding a paper width that is 100 inches wide, I was thinking of just using multiple pages.
Thanks,
Linda

Hi Linda,
Try inserting an OLEDB object and select a bitmap and insert a blank bitmap in report header. Now go to preview and right click on OLEDB Object go to format graphic>picture>change the width of the picture
If the width exceeds more than the width of the page then it create virtual pages.
Hope this helps!

How do I create full width photos for a website with Photoshop - Fireworks - Dreamweaver CS3 ?

Greetings & Help!
I'm trying to create a full width photo layout using Photoshop or Fireworks CS3 and then end with Dreamwaver CS3 without the photo's being tall.
Exactly as the following websites - which all seem to be using the same size of photo or very close to it.
This site is static with full width photos that are not tall.
http://www.jenniferhandyproperties.com/selling
This site is static for the most part and full width photos that are not tall
http://www.gnvpartners.com/web/
This site is Flash with full width photos that are not tall.
expodesigncenter
I would love to create a flash site just like expo but at this point I would settle for a static photo with the same size being the same on each page.
Also I would like my site to be a liquid layout so the photo and everything else (text, Links etc) on the page flows correctly.
The problem...
I'm trying to use photo's from Istockphoto.com. The size of the photo's they offer are
425 x 282 px (5.9" x 3.9")
849 x 565 px (11.8" x 7.8")
1698 x 1131 px (5.7" x 3.8")
I'm selecting horizontal photo's. I do not know how to match the same width, height and appearence as the websites I mentioned above.
If I choose a photo that fits the width then the length is too long. Also if I choose a large photo and have to crop it then most of the detail of the photo is lost.
I'm attempting to create a mock-up for my web in Fireworks CS3 and after search Adobe and www I came across the mock up should be 1004px which would end up being 1024 with vertical scroll bar and small margins.
I also have Photoshop & Flash CS3 but should mention (if you haven't already guess it by now) I am a rookie when it comes to creating a website.
So if you can offer a solution in "Non-Tech Terms" I would appreciate it.
Thank you in advance for your time.

In the second example, the photo is set to background with a tile. The other parts are over top of the photo and done with layers with a background color setting.

How to create a fixed-width column within an APEX 4 interactive report?

This thread is a follow-up to {message:id=9191195}. Thanks fac586.
Partial success: The following code provided by fac586 limits the column width of the Apex 4 interactive report column as long as the column data contains whitespace within a Firefox 3.6 browser:
<pre class="jive-pre">
<style type="text/css">
th#T_DESCRIPTION {
width: 300px;
td[headers="T_DESCRIPTION"] {
width: 300px;
word-wrap: break-word;
</style>
</pre>
Notes:
1. The code above is put into the HTML header section for the page.
2. T_DESCRIPTION is defined as VARCHAR2(2000).
3. The code above works within the Firefox 3.6.12 browser but does not work within the Internet Explorer 7.0.5730.13 browser.
I tried adding "float: left;":
<pre class="jive-pre">
<style type="text/css">
th#T_DESCRIPTION {
width: 300px;
td[headers="T_DESCRIPTION"] {
width: 300px;
word-wrap: break-word;
<font color="red"> float: left;</font>
</style>
</pre>
Notes:
1. "float: left;" does not require whitespace and successfully splits the column between characters in lieu of whitespace.
2. "float: left;" shrinks the cell height and allows the page background to show through... couldn't determine how to fix this.
3. The code above works within the Firefox 3.6.12 browser but does not work within the Internet Explorer 7.0.5730.13 browser.
I've done some more research, but I still haven't discovered how to create a fixed-width column within an APEX 4 interactive report that displays properly within an Internet Explorer 7 browser.
Any ideas and help will be appreciated.

Thanks for your help with this!
<pre class="jive-pre">
what theme are you using?
</pre>
A customized version of theme 15.
<pre class="jive-pre">
Floating a table cell makes no sense (to me anyway).
</pre>
You are correct. I was just trying a different approach ... trying to think out of the box.
<pre class="jive-pre">
Think you'll need to create an example on apex.oracle.com with sample data
if there are any further problems.
</pre>
Great suggestion! The code your provided works in the Firefox 3.6.12 browser, but still doesn't work within my Internet Explorer 7.0.5730.13 browser.
UPDATE:
I have recreated the problem at apex.oracle.com, you can use the following information to check it out:
URL: http://apex.oracle.com/pls/apex/f?p=43543:100::::::
Workspace: IR_FIXED_WIDTH_COLS
Username: GUEST
Password: Thx4help
Application: 43543 - CM_RANDY_SD
Note: Table name is TEST_DATA
The following code provided by fac586 works in both Firefox 3.6 and IE7 using default theme "21. Scarlet" at apex.oracle.com; however, it doesn't work when I use a copy of our customized theme "101. Light Blue":
<pre class="jive-pre">
<style type="text/css">
.apexir_WORKSHEET_DATA {
th#T_DESCRIPTION {
width: 300px;
max-width: 300px;
td[headers="T_DESCRIPTION"] {
max-width: 300px;
word-wrap: break-word;
</style>

</pre>
Any idea what in the theme could be causing the fixed width column to be ignored in IE 7?

How to detect USB Flash Drive name in LabVIEW

Hi there
I was looking for how to detect a USB Flash Drive name in Labview
appearently every time i insert USB Flash Drive in a computer, windows assign it a different name
once "J:" and sometimes "M:"
Is there anyway to obtain USB Flash Drive name programmatically in Labview ?
Because in my program an user shouldn't be able to access HDD Drives except his USB Flash Drive (for inserting some file ...)
thank you and excuse me for my poor english

I was able to get the demo.vi to load, but it could not load the other two because there is no block diagram associated with those. I'm not sure why this is. I haven't had any issues with other llbs before.

How do I change the width of column "rating"

all columns are variable in widht. but not "rating" (stars). How do I change the width of column "rating"?

Hi Emkaha,
By the way the column "last played" can be reduced to a size which display the date "incorrect" as well (you'll see only the first number of the date which wouldn't make any sense too, but it is possible).
True, but if you see date of "1" you will know you are not seeing a full date. If you see 2 stars, it is a valid value, even if it is not correct. At least, that is my supposition about why it is designed the way it is.
Having said that, the extra width in the German version -- the Wertung column is wider than needed for 5 stars -- does seem odd. In the English version for Windows PC, the Rating width is just enough for 5 stars. You can report this to Apple via the iTunes Feedback page.

How can i change the width of a webapp depending on the view?

In Dashcode how can i change the width of the web app depending on the width of the view. I am using the stack layout.
For example if view 1 had a width of 400 px
the web app would have a width of 400 px
if i changed to a view with a 400 px
the webap would change to have a width of 400 px
it automatically adapts the the hight of a view how do i do the same with the width.

While they may auto adjust to what it thinks is a correct width, far too often it allocates way too much room and that causes lists with 4 columns to be much longer than they need to be and without the ability to adjust them, lists look strange.
http://twitpic.com/23ro09/full is an example of the first column having been allocated too much room.

How to detect the Acrobat Browser Plug-in version installed on a users system for non-IE browsers?

How to detect the *Acrobat Browser Plug-in version* installed on a users system, on Firefox, Safari, Opera, etc?
Or one script for detecting Plug-in version for major browsers. Need full example code.

Wrote an article on this with code samples (Javascript + HTML) - basically there are differences between IE and other browsers. Chrome natively comes with the Chrome PDF Viewer so I've incorporated that in my detection script.
The script detects the browser type, and the installed acrobat version...

How to detect the path of Temp directory

I am writing a class library which allows users to manipulate a database in the web server java applications/applets. In my logic the Application/Applet communicate with a CGI script/Servlet in the server and that do all the database handling. My objective is to make the Client independant from the Database Drivers, and to some restrictions and possible security threats that can arrice when accessing the database directly.
99% of the work is done and now I am doing the fine tuning.
My Problem:
When the user downloading a blob object from the server database. each time the program read the blob it will get a new copy from the server. This is not good if the blob is large (few 100 megs) . So I am going to implement a cache system. but the problem is If I am caching in the memory it will not support large objects (Memory is a limited factor). So the preferance is use the Temperary files but I do not know how to detect the path to temperary folder.
And my 2nd questions is are the applets allowed to write and read in temperary folder.

The Java default temporary file path can be determined with
System.getProperty("java.io.tmpdir")This is typically the same value as the os environment variable

How to detect color pages in a PDF?

I am using a C++ Acrobat plug-in do read/edit a PDF file.
I need to get the total number of pages in the PDF as well as the page numbers of color pages.
So far I have been able to get the total number of pages using PDDocGetNumPages() without any trouble.
However, I cant seem to find an API that lets me know whether a particular page is color or not. Is there a way to do this?
Thanks in advance!

But what if there is RGB data that means black or gray (R == G == B), does that mean black or RGB?
There is some sample code in the SDK for iterating over the content in the PDF, and then you can get the colorspace and the color of each object.
But you really need to do some background research on colors & colorspaces to properly achieve this goal.

How do I save the width and height of a photo for repeated use?

How do I save the width and height of a picture for repeated use, rather than having to enter it each time in the 'new file' box?
Thanks, Ed Jackson.

It could be that I'm older and have forgotten. I'm now 73 and will admit I have forgotten many things over the years. I have been using Photoshop since Photoshop version 3. And can not really recall which features or changes were made in ever version of Photoshop I have installed. Adobe has added many features over the years. The number of bugs introduce has also greatly increased after CS3. "New Doc Sizes.psp" in your user id preferences is edited using the two buttons in the new document dialog.
As for guide lines in new documents Photoshop CS6 or CC seem to add some for video file presets with guide lines. I do not know how to edit or add guide line to new doc presets. Guide line actions are easy to create. I have also seem some guideline in new documents when I did not expect any perhaps a new bug. Photoshop like most software has bugs. If you do not see Adobe new presets perhaps you copied an old "New Doc Sizes.psp" over Adobe's newer default file or Adobe migrared you presets and wand wiped their presets out. There are bugs. Close Photoshop down and rename your current "New Doc Sizes.psp" in you user id Photoshop cc preferences folder and start Photoshop it will add a dedault "New Doc Sizes.psp" file see if you see Adobe new presets in the new doc pull down when you select video and film...
