Can't figure out why my navbar gets all pixelated online?

Hi Everyone,
I'm designing a floating site. My workflow is PS=====>Fireworks====>Dreamweaver. I made a navbar in FW with a transparent background and exported html to dreamweaver. I inserted the fireworks htm, put it online and it looks terrible. You can see it here:
http://www.njtraininggrounds.com/thirddaydesign.com/identity.html
Don't worry about the portfolio button, I know what's going on there. But I can't figure out why there is "stairstepping" on the logo and on all the navbar buttons. This is the first time I've ever created a floating site. I just put a jpeg for repeat using the dreamweaver css, and then inserted the rest in a table.
Could anyone give me an idea of what I'm doing wrong? Thanks so much.

There's no problem with using PNG8, PNG24, or PNG32, other than the huge
weight of the latter two. But there's no need to go PNG here.
Personnaly I see only advantages in using PNG. The good thing about using PNG for graphics like this is that it does not tie you to a background with a certain color. like a GIF with a colored matte does. Should you wish to change your background color later you can keep on using your menu buttons. There is no need to prepare new graphics for the menu just because you change a background color or image.
As for the "huge" weight of the PNG file, I'd say that depends on your definition of "huge"
If you compare the filesizes of a simple graphic like that, I see no big improvement by using GIF.

I can't figure out why I'm getting a Null Pointer Exception

I'm writing a program that calls Bingo numbers. I got that part of the program to work but when I started adding Swing I kept getting a Null Pointer Exception and I don't know how to fix it. The Exception happens on line 15 of class Panel (g = image.getGraphics();). Here is the code for my classes. I'm still not finished with the program and I can't finish it until I know that this issue is resolved.

The javadoc of createImage() states that "The return value may be null if the component is not displayable."
Not sure, but it may be that you need to call init() after this.setVisible(true).

I think it has something to do with the way I'm specifying the "path" but i'm not sure.

You appear to be naming the buttons the same as the Sound objects. You will need to define different names for one or the other.

Yes, I did try to go on my settings>wifi and was waiting for any wifi signals to pick up, but nothing shows up. But on my PC I get a whole list of networks to choose from. Regarding my neighbor, I already have her password that is why I was able to get it on my PC, the problem is that the mini Ipad is not picking any signal neither can it locate me when I go to maps.

Is she facetiming your phone number or email address, b/c email address should not do that.. Was there an old iPhone associated with your number or email? I've seen texts show up on long "deactivated" devices..

Can someone please tell me a simple but effective method for burning a slideshow to DVD? Now that the connection between iPhoto and iDVD no longer exists, I can't figure out a way to get there with an acceptable quality result.

Can someone please tell me a simple but effective method for burning a slideshow to DVD? Now that the connection between iPhoto and iDVD no longer exists, I can't figure out a way to get there with an acceptable quality result.

Export the slideshow out of iPhoto as a QT movie file via the Export button in the lower toolbar. Select Size = Medium or Large.
Open iDVD, select a theme and drag the exported QT movie file into the open iDVD window being careful to avoid any drop zones.
Follow this workflow to help assure the best qualty video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
If iDVD was not preinstalled on your Mac you'll have to obtain it by purchasing a copy of the iLife 09 disk from a 3rd party retailier like Amazon.com: ilife 09: Software or eBay.com. Why, because iDVD (and iWeb) was discontinued by Apple over a year ago.
Why iLife 09 instead of 11?
If you have to purchase an iLife disc in order to obtain the iDVD application remember that the iLife 11 disc only provides themes from iDVD 5-7. The Software Update no longer installs the earlier themes when starting from the iLIfe 11 disk nor do any of the iDVD 7 updaters available from the Apple Downloads website contain them.
Currently the only sure fire way to get all themes is to start with the iLife 09 disc:
This shows the iDVD contents in the iLife 09 disc via Pacifist:
You then can upgrade from iDVD 7.0.3 to iDVD 7.1.2 via the updaters at the Apple Downloads webpage.

Can't figure out why my iMac is so slow

My 2.16 Intel Core 2 Duo iMac has suddenly slowed to a crawl, and I can't figure out why. Opening anything (including a Finder window) results in a 30 second to 5 minute lag. I've seen the spinner more in the last month than I did in the previous 4+ years of owning it.
Since it's my spare machine now, I completely re-formatted the hard drive and did a fresh install of 10.4.7 from the discs it shipped with. I have run the Apple Hardware Test, and everything tests OK. Disk Utility tells me there's nothing wrong with the disk, and all permissions are good. What am I missing?

Earl...
I know you said you reformatted the drive but just in case, how much free space on the startup disk?
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you have a minimum of 15% free disk space.
fresh install of 10.4.7
Most recent version for Tiger is v10.4.11. Have you tried updating the software from the Apple menu > Software Update?

Well, one extreme that I eventually had to go to was inserting a new row with only the primary keys, which were numerical columns, while just setting the strings to empty values.
INSERT INTO Courses VALUES(?,?,?,1,0,?,'','','','','','','','','')
Access finally seemed to handle this without barfing.
Then, I updated each string column ...if you can believe it ...one at a time in a for loop from a custom 'RowUpdateSet' object. This actually worked well because eventually I also used it to update the row when necessary, and to only update columns whose values had changed. One teeny weeny snippet from a great deal of code looked like this...
for ( int i=1; i<length; i++ ) {
    if ( updateSet.getUpdateColumn( i ) ) {
      synchronized ( updateSet ) {
        scrollResults.updateObject(i,(String)updateSet.getUpdateValue(i));
        scrollResults.updateRow();
}I guess I will likely get flamed for participating in this whole discussion, because it all does become quite irrational. I can see why peoples initial response is likely ..."what, couldn't you even debug your own sql string bozo?" All I know is, there seems to be insert statements that Access just mysteriously refuses to perform ...and it has nothing to do with terminated strings or syntax errors. How you choose to perservere and 'get the job done' is probably as unique to each individual as is the whole mysterious error in the first place. I just got tired of staring at what appeared to be a totally disfunctional environment and decided to go around the problem and get done with the project ...which eventually worked like a charm.
This is exactly what I meant when I said don't look too closely or you might wind up distrusting this technology you are working with on a day to day basis. Frankly, the more I work with technology the more I realize that I, for example, will never use my credit card over the web (particularly with .NET in the picture). I am sure you can find another way to get to the results you want if you think about it creatively. I got my project done. I just didn't get there in the way I had expected I would. Maybe that's not even a bad thing, even though it can be extremely frustrating at times. When we look at all the disclaimers that come with software these days, or look at faster and faster computers that just run slower and slower, maybe we shouldn't expect so much from technology. At least Java allows you to write your own logic and often work around these impediments ...which is still alot better than being stuck with .COM libraries that force you to abandon a project half way through when you find out the library fails to live up to its claims in the reference manual.
Sorry your project is on hold at the moment. If no one else answers, start a new thread that asks your question again, and I will butt out. Maybe there is someone who has found out what causes this issue. After all, I can only speak from my own experiences ...and I am far from being an authority on any issue surrounding technology. Good luck, and don't give up. I am sure there is a way to get where you want to go.
After saying all that, I realize kev wrote a response while I was composing this one. As he implores, yes ...do be certain you have eliminated all the obvious possibilities before you adventure into any painfull work-arounds. Really, I wish you all the best of luck.

1) The best way to relocate the iTunes library folder is to move the entire iTunes folder with all subfolders to the new path, then press and hold down shift as start iTunes and keep holding until prompted to choose a library, then browse to the relocated folder and open the file iTunes Library.itl inside it.
If you've done something different then provide some more details about what is where and I should be able to help.
2) Purchases on the device should automatically transfer to a Purchased on <DeviceName> playlist, but it my depend a bit on whether automatic iCloud downloads are enabled. If there is a cloudy link then the transfer might not happen. You can use File > Devices > Transfer Purchases. In iTunes you should also check out iTunes Store > Quick Links > Purchased > Music > Not on this computer.
3) Backup the device, then immediately restore it. In some cases you need to add a restore as new device into that equation. Obbviously not to be attempted until you're sure all your media is in your library. See Recover your iTunes library from your iPod or iOS device should it be needed.
4) I believe there is complimentary 1 incident 90-day support with hardware purchases, but no free software support for iTunes itself. AppleCare gets you a different level of support.

Can't figure out why colors don't totally change when you select type with curser? It looks like it has by looking at it, but when you highlight the area after the old color is still there. It happens with objects to. Driving me NUTZ. Help!

Select the text, and open the Appearance palette (Come on guys, text highlight is irrelevant, it happens to objects too says the OP), and see what's listed there. For a simple text object, there should only be a line item "Type", followed by "Characters", and when double-clicked the Characters line item expands to tell you the stroke and fill color. For a basic object, there should be a fill and/or stroke.
What happens sometimes, is that you end up adding extra strokes/fills to objects or text, and the appearance palette is where that will be noted. Especially when you are dealing with groups, and/or picking up a color with the eyedropper, you may inadvertently be adding a fill or stroke on top of something. You can drag those unwanted thingies from the Appearance palette into its own little trash can.

I tried to Skype someone but I can't see them but they can see me and I can't figure out why?

I'll guess that you're upgrading from Snow Leopard? You should be able to start using your original install dvd by inserting the disc and restarting while holding the C key. Run Disk Utility from your install disc and try to repair the drive. Then try the upgrade again.

Apex bug? Items being cleared in session state - can't figure out why

I have an item that is being submitted with a value but is then being overwritten and set to null. I can't see any reason why the submitted value is being overwritten with null.
I have been debugging this problem for most of the day and can't figure out what is happening and was hoping someone in the forum might be able to shed some light.
Some details:
The item is on Page 0, has source type of "PL/SQL Expression or Function", a source expression of "V('REQUEST')", and Source Used = "Always".
I viewed the HTML source of the rendered page and can see the following HTML, so I know the item has a value when the page is rendered:
<input type="hidden" id="RENDER_REQUEST" name="p_t08" value="EDIT" />
I have used Firebug to view the HTTP POST body and can see that p_t08 is being correctly submitted with a value of "EDIT" in the post body.
When I run the page in debug mode and then view the debug log, I see that Apex is indeed setting this item to null:
     0.01500     0.01600     A C C E P T: Request="WIZ_NEXT"
     0.23400     0.00000     Session State: Save form items and p_arg_values
     0.24900     0.01600     ...Session State: Save "BRANCH_TO_PAGE_ID" - saving same value: ""
     0.24900     0.00000     ...Session State: Save "ROWS_PER_PAGE" - saving same value: ""
     0.26500     0.01500     ...Session State: Save "P0_CLEAR_WS" - saving same value: ""
     0.26500     0.00000     ...Session State: Saved Item "RENDER_REQUEST" New Value=""
I can't figure out why the item is being set to null.
This problem also does not occur on every page. The pages in question are a multi-step "wizard" that allows the user to navigate between steps with "Next" and "Previous" buttons. Since this is a page 0 item, it appears on every page in the wizard so I'd expect it to behave the same. When you open the wizard at step 1 and press next to go to step 2, the item (RENDER_REQUEST) is set correctly on step 2 of the wizard, BUT when you then click Next to go to step 3, RENDER_REQUEST is null on step 3. If you open the wizard at step 2 and press Next, RENDER_REQUEST is null on step 3.
I did find a work around, but it doesn't make any sense why it would work: if I move the RENDER_REQUEST item from the "Footer Items" region to a page level item (by using Edit All and setting its region to blank), then the problem goes away. If I move it back to the "Footer Items" region the problem reoccurs.
I am working on Application Express 4.0.2.00.07 on Oracle Database 11g Enterprise Edition Release 11.2.0.1.0.
Any help would be greatly appreciated!
Thank you.

Hi Patrick,
Thanks for the quick response. Unfortunately, I can't reproduce this on apex.oracle.com due because the app requires PL/SQL packages to be installed in several schemas, including some that require system grants (I gave a presentation at Oracle Open World a couple of years ago on some of the techniques I used in building this application that you attended; I think the session was called "Building Large Commercial Applications with Oracle Database 11g and Oracle Application Express").
Is there another way we can work together to debug this without reproducing it apex.oracle.com? For example, if you could send me an instrumented version of the APEX_040000.F procedure (or whatever procedure is clearing the session state) that has some additional APEX_APPLICATION.DEBUG calls, I could install it on my server, reproduce the error and send you the output.
Thank you,
Eric

Can't figure out why I'm dropping frames during capture

I'm dropping frames when capturing 1-hour Mini DV tapes and I can't figure out why.
I'm capturing on a Mac Pro (Early '08) with 8 GB of memory running FCP 7.0.3 and OS X 10.6.6. I'm capturing to a 4 TB G-Speed eS (eSATA) formatted as RAID 5 (Non-Journaled Extended) with about 750 GB of remaining space. I'm capturing via FireWire with a Canon GL-2. This should be a breeze for this system.
I've run Apple Disk Utility, Disc Warrior 4 and Techtool Pro 5 on the drives and they seem to be fine. I've unplugged all USB and FireWire devices besides the keyboard and mouse. No virus protection or background utilities are running. I've trashed preferences. AJA System Test shows a 286 MB/s write speed and 254 MB/s read speed. Blackmagic Disk Speed Test shows a 312 MB/s write speed and a 379 MB/s read speed. No other applications besides FCP are running. I edit 1080p HD footage on this system all day long with no issues but when I try to capture DV SD footage, I run into issues.
The dropped frames error does not ever occur in the same place on the tapes. The tapes are brand new and don't seem to have any time code issues. The only thing I haven't done is to defragment the hard drives. I wouldn't think that capturing simple DV video would be that demanding; the defragment for a 4 TB RAID would likely take 2 or 3 days.
Any other ideas on what's going on and how to try to fix it? Thanks!

Thanks for the prompt reply, Studio X. Yes, I'm using FireWire Basic and no other FireWire devices. I've switched FireWire cables, although I doubt that's the issue as the cable I was using was brand new and fit snuggly. Unfortunately, I don't have an alternate playback device right now. Would switching to Non-controllable device capture settings be worth a try?

Can't figure out why my navbar gets all pixelated online?
