Have you tried reinstalling InDesign? It sounds like something's wrong with your color profiles.
That's the only thing I haven´t tried, but I will and post about it.
I found a workaround though: If I set my desired color settings in InDesign, but don´t save them, then it works; I no longer get the error message if I go to Edit> Color Settings...
The color settings dialog box says that my Creative Cloud applications are unsynchronized, because I´m not using the .csf file previously synchronized using Bridge, but the settings are exactly the same and I can get around it. Colors actually work as they should.
So this seems to be a problem with InDesign accessing any saved color settings file. My color profiles aren´t wrong, because all other programs in the Suite use them with no trouble.
InDesign just wants to have it's own, non saved, color settings. How about that? Guess I got the selfish version . -
Is it possible to connect 2 Creative Web Cameras to one computer?
Hi all.
I want to connect 2 Web cameras to one computer and see li've video in two windows simultaneously. I have bought 2 identical LabTec Web Cameras, and when I connect to both cameras simultaneously the both video streams freezes.
Does anybody have any experience connecting 2 identical Creative Web cameras to one computer? Can they stream simultaneously without freezing?
I am planning to buy 2 Creative WebCam NX Pro, can they stream simultaneously without freezing?
Im using Windows XP SP2 and USB 2.0.
Regards,
HemmingsenThank you for your reply!
I have tried to connect to different Web cameras to the same PC - and that worked!
I have tried to connect to identical LabTec Web cameras to the same PC - and that did NOT work!
It looks like it could be a driver problem.
I am working on a litte robot project and in connection to that, I need two identical cameras simultaneously to take 2 pictures. I that way I can analyse the 2 pictures and calculate the distance to objects. But the two pictures MUST be as identical as possible - therefore I want to use 2 identical cameras.
I would like if anybody who has 2 identical Creative Web cameras could do this little test:
1) Connect 2 identical Creative Web cameras to 2 different USB controllers (WebCam NX Pro preferred)
2) Open "My computer"/"WebCam "
3) Open "My computer"/"WebCam 2"
4) Check that both windows shows li've video simultaneously
5) Reply the result and the camera model to me
I get bankrupt if I buy more cameras that I cannot use - so I hope anybody can help me.
Regards,
Hemmingsen

Does Creative have any plan to support my web cam 550, or do i have throw it out?
Please advise.You don't need to use the headset. You can just use the regular devices plugged into the sound card of your computer which would include a microphone and speakers. If you have a laptop, a microphone and speakers are usually built in. The headset just tends to be more private and convenient and creates fewer problems when you're a alone.

Creative video master web cam 2 usb version XP drivers required
Does anyone have a copy of a driver that will work under windows XP for the videoblaster web cam 2 ?
DM, I am pretty sure it does support WMP 0 playlists; I think 2..02 did as well. I do know that 2.20.05 supports Yahoo! Music Engine playlists; I had two albums with the exact same title but by different artists (worse, one of them has a collaboration which makes it impossible to select the entire album in the Artists section of the library), and used YME playlists to properly separate them in my Micro.
Cat, congratulations on the official release of 2.20.05. I have a few questions for you:
Can you confirm that the officially-released 2.20.05 firmware is identical to what was released on Audible's website? (Other than Audible packaging theirs in a zip file, of course.)</LI>
I noticed that "locked charging" isn't listed in the release notes; that was also a ..0 feature which was NOT present in 2..02. I have confirmed thru testing that "locked charging" works on 2.20.05 with a third-party charger (unofficial use); presumably it also works with USB connections on PCs without MTP (official use, but I can't test it). The one report I read of problems with "locked charging" on 2.20.05 was due to the user NOT locking his Micro BEFORE plugging in. Can you obtain official confirmation that "locked charging" is a 2.20.05 feature, and then add the blurb about it from the ..0 release notes to the 2.20.05 release notes?</LI>
And can I add to the firmware wishlist changes to the Albums section of the library, so that two albums by different artists with the exact same title are NOT mixed up? (That might need tagging software that can properly distinguish album artists from those on individual tracks, like WMP 0 does.)</LI>

I need in web cam that would be work in Linux.
Please write list of web cam that have linux drivers.
I asked my reb at CDW who sent an e-mail to Creative labs sales and was told the the Live Cam Optia Pro had drivers available for linux
This camera supports UVC (USB Video Class) whick is supported with in Linux see http//linux-uvc.berlios.de.
The driver is included on the Suse Enterprise desktop 0-2 distr, but so far I have not been able to get the camera to work correctly.
I am still working on the problem. -
Capture Web Cam image in APEX and Upload into the Database
Overview
By using a flash object, you should be able to interface with a usb web cam connected to the client machine. Their are a couple of open source ones that I know about, but the one I chose to go with is by Taboca Labs and is called CamCanvas. This is released under the MIT license, and it is at version 0.2, so not very mature - but in saying that it seems to do the trick. The next part is to upload a snapshot into the database - in this particular implementation, it is achieved by taking a snapshot, and putting that data into the canvas object. This is a new HTML5 element, so I am not certain what the IE support would be like. Once you have the image into the canvas, you can then use the provided function convertToDataURL() to convert the image into a Base64 encoded string, which you can then use to convert into to a BLOB. There is however one problem with the Base64 string - APEX has a limitation of 32k for and item value, so can't be submitted by normal means, and a workaround (AJAX) has to be implemented.
Part 1. Capturing the Image from the Flash Object into the Canvas element
Set up the Page
Required Files
Download the tarball of the webcam library from: https://github.com/taboca/CamCanvas-API-/tarball/master
Upload the necessary components to your application. (The flash swf file can be got from one of the samples in the Samples folder. In the root of the tarball, there is actually a swf file, but this seems to be a different file than of what is in the samples - so I just stick with the one from the samples)
Page Body
Create a HTML region, and add the following:
<div class="container">
<object id="iembedflash" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="320" height="240">
<param name="movie" value="#APP_IMAGES#camcanvas.swf" />
<param name="quality" value="high" />
<param name="allowScriptAccess" value="always" />
<embed allowScriptAccess="always" id="embedflash" src="#APP_IMAGES#camcanvas.swf" quality="high" width="320" height="240"
type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" mayscript="true" />
</object>
</div>
<p><a href="javascript:captureToCanvas()">Capture</a></p>
<canvas style="border:1px solid yellow" id="canvas" width="320" height="240"></canvas>That will create the webcam container, and an empty canvas element for the captured image to go into.
Also, have a hidden unprotected page item to store the Base64 code into - I called mine P2_IMAGE_BASE64
HTML Header and Body Attribute
Add the Page HTML Body Attribute as:
onload="init(320,240)"
JavaScript
Add the following in the Function and Global Variable Declarations for the page (mostly taken out of the samples provided)
//Camera relations functions
var gCtx = null;
var gCanvas = null;
var imageData = null;
var ii=0;
var jj=0;
var c=0;
function init(ww,hh){
gCanvas = document.getElementById("canvas");
var w = ww;
var h = hh;
gCanvas.style.width = w + "px";
gCanvas.style.height = h + "px";
gCanvas.width = w;
gCanvas.height = h;
gCtx = gCanvas.getContext("2d");
gCtx.clearRect(0, 0, w, h);
imageData = gCtx.getImageData( 0,0,320,240);
function passLine(stringPixels) {
//a = (intVal >> 24) & 0xff;
var coll = stringPixels.split("-");
for(var i=0;i<320;i++) {
var intVal = parseInt(coll);
r = (intVal >> 16) & 0xff;
g = (intVal >> 8) & 0xff;
b = (intVal ) & 0xff;
imageData.data[c+0]=r;
imageData.data[c+1]=g;
imageData.data[c+2]=b;
imageData.data[c+3]=255;
c+=4;
if(c>=320*240*4) {
c=0;
gCtx.putImageData(imageData, 0,0);
function captureToCanvas() {
flash = document.getElementById("embedflash");
flash.ccCapture();
var canvEle = document.getElementById('canvas');
$s('P2_IMAGE_BASE64', canvEle.toDataURL());//Assumes hidden item name is P2_IMAGE_BASE64
clob_Submit();//this is a part of part (AJAX submit value to a collection) two
}In the footer region of the page (which is just a loading image to show whilst the data is being submitted to the collection [hidden by default]) :<img src="#IMAGE_PREFIX#processing3.gif" id="AjaxLoading"
style="display:none;position:absolute;left:45%;top:45%;padding:10px;border:2px solid black;background:#FFF;" />If you give it a quick test, you should be able to see the webcam feed and capture it into the canvas element by clicking the capture link, in between the two elements - it might through a JS error since the clob_Submit() function does not exist yet.
*Part 2. Upload the image into the Database*
As mentioned in the overview, the main limitation is that APEX can't submit values larger than 32k, which I hope the APEX development team will be fixing this limitation in a future release, the workaround isn't really good from a maintainability perspective.
In the sample applications, there is one that demonstrates saving values to the database that are over 32k, which uses an AJAX technique: see http://www.oracle.com/technetwork/developer-tools/apex/application-express/packaged-apps-090453.html#LARGE.
*Required Files*
From the sample application, there is a script you need to upload, and reference in your page. So you can either install the sample application I linked to, or grab the script from the demonstration I have provided - its called apex_save_large.js.
*Create a New Page*
Create a page to Post the large value to (I created mine as 1000), and create the following process, with the condition that Request = SAVE. (All this is in the sample application for saving large values).declare
l_code clob := empty_clob;
begin
dbms_lob.createtemporary( l_code, false, dbms_lob.SESSION );
for i in 1..wwv_flow.g_f01.count loop
dbms_lob.writeappend(l_code,length(wwv_flow.g_f01(i)),wwv_flow.g_f01(i));
end loop;
apex_collection.create_or_truncate_collection(p_collection_name => wc_pkg_globals.g_base64_collection);
apex_collection.add_member(p_collection_name => wc_pkg_globals.g_base64_collection,p_clob001 => l_code);
htmldb_application.g_unrecoverable_error := TRUE;
end;I also created a package for storing the collection name, which is referred to in the process, for the collection name:create or replace
package
wc_pkg_globals
as
g_base64_collection constant varchar2(40) := 'BASE64_IMAGE';
end wc_pkg_globals;That is all that needs to be done for page 1000. You don't use this for anything else, *so go back to edit the camera page*.
*Modify the Function and Global Variable Declarations* (to be able to submit large values.)
The below again assumes the item that you want to submit has an item name of 'P2_IMAGE_BASE64', the condition of the process on the POST page is request = SAVE, and the post page is page 1000. This has been taken srtaight from the sample application for saving large values.//32K Limit workaround functions
function clob_Submit(){
$x_Show('AjaxLoading')
$a_PostClob('P2_IMAGE_BASE64','SAVE','1000',clob_SubmitReturn);
function clob_SubmitReturn(){
if(p.readyState == 4){
$x_Hide('AjaxLoading');
$x('P2_IMAGE_BASE64').value = '';
}else{return false;}
function doSubmit(r){
$x('P2_IMAGE_BASE64').value = ''
flowSelectAll();
document.wwv_flow.p_request.value = r;
document.wwv_flow.submit();
}Also, reference the script that the above code makes use of, in the page header<script type="text/javascript" src="#WORKSPACE_IMAGES#apex_save_large.js"></script>Assuming the script is located in workspace images, and not associated to a specific app. Other wise reference #APP_IMAGES#
*Set up the table to store the images*CREATE TABLE "WC_SNAPSHOT"
"WC_SNAPSHOT_ID" NUMBER NOT NULL ENABLE,
"BINARY" BLOB,
CONSTRAINT "WC_SNAPSHOT_PK" PRIMARY KEY ("WC_SNAPSHOT_ID")
create sequence seq_wc_snapshot start with 1 increment by 1;
CREATE OR REPLACE TRIGGER "BI_WC_SNAPSHOT" BEFORE
INSERT ON WC_SNAPSHOT FOR EACH ROW BEGIN
SELECT seq_wc_snapshot.nextval INTO :NEW.wc_snapshot_id FROM dual;
END;
Then finally, create a page process to save the image:declare
v_image_input CLOB;
v_image_output BLOB;
v_buffer NUMBER := 64;
v_start_index NUMBER := 1;
v_raw_temp raw(64);
begin
--discard the bit of the string we dont need
select substr(clob001, instr(clob001, ',')+1, length(clob001)) into v_image_input
from apex_collections
where collection_name = wc_pkg_globals.g_base64_collection;
dbms_lob.createtemporary(v_image_output, true);
for i in 1..ceil(dbms_lob.getlength(v_image_input)/v_buffer) loop
v_raw_temp := utl_encode.base64_decode(utl_raw.cast_to_raw(dbms_lob.substr(v_image_input, v_buffer, v_start_index)));
dbms_lob.writeappend(v_image_output, utl_raw.length(v_raw_temp),v_raw_temp);
v_start_index := v_start_index + v_buffer;
end loop;
insert into WC_SNAPSHOT (binary) values (v_image_output); commit;
end;Create a save button - add some sort of validation to make sure the hidden item has a value (i.e. image has been captured). Make the above conditional for request = button name so it only runs when you click Save (you probably want to disable this button until the data has been completely submitted to the collection - I haven't done this in the demonstration).
Voila, you should have now be able to capture the image from a webcam. Take a look at the samples from the CamCanvas API for extra effects if you wanted to do something special.
And of course, all the above assumed you want a resolution of 320 x 240 for the image.
Disclaimer: At time of writing, this worked with a logitech something or rather webcam, and is completely untested on IE.
Check out a demo: http://apex.oracle.com/pls/apex/f?p=trents_demos:webcam_i (my image is a bit blocky, but i think its just my webcam. I've seen others that are much more crisp using this) Also, just be sure to wait for the progress bar to dissappear before clicking Save.
Feedback welcomed.Hmm, maybe for some reason you aren't getting the base64 version of the saved image? Is the collection getting the full base64 string? Seems like its not getting any if its no data found.
The javascript console is your friend.
Also, in the example i used an extra page, from what one of the examples on apex packages apps had. But since then, I found this post by Carl: http://carlback.blogspot.com/2008/04/new-stuff-4-over-head-with-clob.html - I would use this technique for submitting the clob, over what I have done - as its less hacky. Just sayin. -
Vf-0040 instant web cam is not working good
This is my first web cam it's a hand me down ,i spent days trying to figure out how to get it working until i found out i needed 2 different software's to run it. Download the Creative WebCam Center and WCC_PCApp_US_1_71_02 driver and know it's sort of working after all my effort.
It is so blurry i can't even make out my own face? I cleaned the lens with alcohol and a cue tips and it wasn't any better than before and there is what seems to be a fake focus adjustment knob but it doesn't move? I played with the software and used the advanced settings and got no noticeable difference except in the color of the blur that's supposed to be my face.
What did i do wrong or is the web cam wrongHi there @Vonita
Welcome to the HP Support Forums!
I understand that you are having problems with your webcam, and I am happy to help. Firstly, can you post the full product number and the operating system you are using? That would help me to direct you to the correct drivers.
How Do I Find My Model Number or Product Number?
Is the Windows Version on My Computer 32-bit or 64-bit?
For now, you can take a look at whichever of these most applies to your system.

Hi everyone,
I came to these forums after I heard of the recent developments from Creative Labs. After reading what many people wrote, I?thought I would share?the story of how Creative became a part of my life.
I was twelve years old when I first learned of Creative. I had saved up enough money over a year and a half?and finally bought a 486 DX-2 50Mhz computer. I cannot tell you how many lawns I mowed and dri'veways I shoveled. Take a minute to remember what prices were like in the early 990s and you'll understand why it took so long. I would have been able to get a sound card included with the computer had I saved for another month or two, but I was twelve - I wasn't going to wait anymore!
Two?months after that purchase, I had saved up enough money to buy a sound card and speakers. Finally my system would be complete!? I started looking for a sound card and heard from many people that SoundBlasters were the only kind I should consider. Thus, the SoundBlaster 6 was my first sound card. Indeed, it was the first component I ever installed in a computer and it went flawlessly.
Because "Soundblaster" compatibility was important back then, I purchased only Creative products. Even as a teenager, I noticed the bloatware that was starting to get bundled with the drivers. I also noticed that the quality of the drivers was deteriorating, but I was always able to make them work well most of the time. There were a few blue screens of death, but I just shrugged and rebooted.
As we approach the present, it is clear to me the trend I noticed has reached a breaking point. I was stunned when I saw that Creative had the nerve to tell someone who was doing their job for them to stop. For this reason, my sound card has been placed in the garbage and I am using the onboard audio included with my Shuttle system. On a side note, installing those drivers was a cakewalk compared to some of the installations I went through with Creative products.
It is obvious to me, someone who has only been without a Creative sound card for two months, that the company either has no idea what they are doing or does not care. I will not purchase another Creative product again, nor recommend that anyone do so, until new management is present and is turning the company around. This includes making higher quality, less bloated, more stable drivers that activate all of the features present on the card and work on all operating system in the same way.
I have signed the petition (link below), and encourage people to do the same. I know perfectly well that a petition is unlikely to change the policies of management, but it is at the very least one more way to make my displeasure heard. I am number 26 on the petition, and I hope many more will sign so that the extent of their customers' displeasure becomes known.
That is my Creative story, and it is a sad one. I am sad to see a company so capable of producing excellent hardware fall into the trap that is poor management.
To Creative: Please turn around your company and realize that hardware and software must work together seamlessly. Please reorganize your management team and put in place individuals who understand how to build relationships with customers. Please realize that people who pay you money have taken the time to earn it and are worthy of higher levels of support for their products. And finally, please recognize that punishing a member of the community who picked up slack where you left off is a horrendous way to build customer relationshi
ps.
Indeed, that is how you are losing mine.
I wish everyone on here the best, and thank you for reading this little story. I was told growing up that words can move mountains, so I encourage everyone to leave some words of their own.
Thank you,
Tim
Link: http://www.petitiononline.com/crtvlabs/petition.htmlCreative was infringing upon Aureal's patents, not the other way around. Yet is was Creative who sued Aureal for patent infringement.
See : http://en.wikipedia.org/wiki/Aureal
On March 5th, 998, [url="http://en.wikipedia.org/wiki/Creative_Labs">Creative Labs[/url] sued Aureal for patent infringement. Aureal countersued because they believed Creative was guilty of patent infringement. After numerous lawsuits Aureal won a favorable ruling in December 999, which vindicated Aureal from these patent infringement claims, but the legal costs were too high and Aureal filed for [url="http://en.wikipedia.org/wiki/Bankruptcy">bankruptcy[/url]. On September 2st, 2000, Creative acquired Aureal's assets from its [url="http://en.wikipedia.org/wiki/Bankruptcy_trustee">bankruptcy trustee[/url] for US$ 32 million. The purchase included patents, trademarks, other property, as well as a release to Creative from any infringement by Creative of Aureal's intellectual property including [url="http://en.wikipedia.org/wiki/A3D">A3D[/url]. The purchase effecti'vely eliminated Creative's only competition in the gaming audio market. It also eliminated any requirements for Creative to pay past or future royalties as well as damages for products which incorporated Aureal's technology.

Updated : No question, just example web cam capture code
Hi,
I posted this example a while back, but it had some cosmetic bugs in it.
Here's an updated version.
Quick Start
1. Install JMF 2.1.1e (performance pack version)
( see imports list in source code if you really want to run it using the older version 2.1.1c )
2. You have to set the JMF_HOME or JMFHOME environment variable. Can't remember which one.
"Nearly sure" it's JMF_HOME.
3. Connect your camera
4. run jmfinit ( may need to do a few times until it detects your camera )
When it does, you're in business, and you can try to run the code
5. Run java -cp .;%JMF_HOME%\lib\jmf.jar JWebCam
known issue
Under Java 1.5 / 5 - When capturing a frame, and then resizing that snapshots JFrame, the image did not always scale up and display.
That does work under Java 1.3.1_06 .
Tested on Win98 2nd edition, Java 1.3.1_06, and Creative Web Cam Pro.
Legal stuff in plain english : This code is available for use by everyone, personal or commercial, no need to mention me in licenses or anything. It's just a demo I knocked up for myself. So I am under no obligation to support this. Use it at your own risk.... that implies you can't blame or sue me for anything that goes wrong.
If you like the code, I'd be happy to hear whereabouts you are in the world :-)
Also note : this is the limits of my JMF experience at present.
If you've a separate question, post it to a new topic!
regards,
Owen ( Dublin, Ireland )

I can get into BIOS and checked Config-CPU, IVT was off, I turned that on. I went to AMT but that kept windows from booting up. EIST is still grayed out. ideas??
