Gui doesn't show when the Thread is dispatched from the main class

Hi all,
I've tried to write a file unzipper class that shows a small frame with 2 progress bars.
The unzipper extends Thread class in order to make it an independant service.
However, when I debug it and use a main function that's written within the class, it works fine, and when I run it by calling it from another main, I only see a frame where the progress window should be, but no window.
Does anyone know what I'm doing wrong? (About the GUI, I know my unzipper isn't the most efficient one:

* This is a file Unzipper;
* It takes a zipped archive, reads it, and decompresses the files within it
* It is a stand alone thread since the user doesn't need to wait for it or whatever;
* It also shows a nice progress bar gui for the user to know how the decompressing works

Make sure that you do not have a stalled download in iTunes - a song or podcast .... if you have a download in there that did not finish, complete that one first. Only one thing can download at a time on the iPad so that could be what is causing the problem.
If that doesn't work - sign out of your account, restart the iPad and then sign in again.
Settings>Store>Apple ID. Tap your ID and sign out. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Go back to Settings>Store>Sign in and then try to update again. Tap one waiting icon only if necessary to start the download stream.
You can also try deleting the waiting icons - tap and hold down on an icon until it wiggles - the tap the X on the icon to delete it. Then try to download again.
You can try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your app preferences and device settings again.

You need to have a JFrame to add your components to.
For example, make your class extend JFrame and set your main panel the ContentPane (assuming that all your components have been added to this panel).
public class SimpleSender extends JFRame {
this.setContentPane(JPanel1);

Report works fine in VS2010 but simply doesn't show when published

Problem:
Crystal Report works fine in VS 2010 but doesn't show when published to web-server, there is no error, it simply doesn't show.
Background:
Installed VS2010 on a freshly installed and fully updated (.net 4.0 is included in the updates) windows server 2003 box with production release Crystal Report 2010. Nothing else is on the server. IIS 6 is running. My web-server and VS2010 is on the same box.
I went ahead and created a new asp.net 4.0 web project called webapplication1. Thereafter, i put a few controls (text-boxes, list-boxes and so on) on the default.aspx page. Then i created a report.aspx page. This page will have the crystal report viewer on it. I went ahead and set the report up without much hassle (got how-to's from the internet). I successfully tested my web app with the built-in testing server, the beautiful crystal report presented exactly what i asked it to. There was one recurring "Sys.Application is null or not an object" hiccup that occured every time during testing when i navigated from the default.aspx page to the report.aspx page (the page the report is on). Clicking ignore or continue on the dialogue box that comes up because of the hiccup will allow testing to continue. Here's a screen-shot of this recurring hiccup.
http://i440.photobucket.com/albums/qq122/ricom_19/Testing-Error.jpg
As i've shown, testing went great, except for the hiccup. I now moved to setup a publish profile. Since my web-server and VS2010 is on the same box this seemed relatively straight forward. All the files went over except the report, i.e. crystalreport1.rpt file. I solved this by setting the build action to 'Content' in the CrystalReport1.rpt properties. I did a republish. Now i have all my files, see screenshot: [http://i440.photobucket.com/albums/qq122/ricom_19/Application-Home-Directory.jpg], on the web-server.
I proceeded to try to browse to my app from another computer on my network. This was successful until i tried to navigate to the report.aspx page that the crystal report is on. The the report.aspx page loaded but the crystal report was simply not on it. No errors, not even the hiccup from testing occured. Its as if the crystal report viewer was never on the page to begin with. Only when i right clicked on the page and 'view source' did i see some remnants of the crystal report viewer.
Here is the Report.aspx page when tested in VS2010:
[http://i440.photobucket.com/albums/qq122/ricom_19/successful-Test.jpg|http://i440.photobucket.com/albums/qq122/ricom_19/successful-Test.jpg]
Here is the Report.aspx page when published to the web-server and browsed to from another computer on the network:
[http://i440.photobucket.com/albums/qq122/ricom_19/Reportviewer-Disappear.jpg|http://i440.photobucket.com/albums/qq122/ricom_19/Reportviewer-Disappear.jpg]
Details of adding report to my web app:
1) Populate my dataset then write the XML schema, reportschema.xml
2) Added the crystal Report to the project then used the wizard to navigate to the reportschema.xml. Of course i had to create new connection in Database expert. see screen-shot:
[http://i440.photobucket.com/albums/qq122/ricom_19/CR-Database-Expert.jpg|http://i440.photobucket.com/albums/qq122/ricom_19/CR-Database-Expert.jpg]
3) I formatted the report the way i wanted it
4) Added the Crystal report viewer on the Report.aspx page
5) In the code-behind of the Report.aspx page i bound the viewer to a report document that is loaded with CrystalReport1.rpt file
see screenshot: [http://i440.photobucket.com/albums/qq122/ricom_19/Report-Page-Code-behind.jpg]
That's it. As mentioned, it tested fine in VS2010 but the viewer doesn't show when i publish to the webserver. I wrote a crystal report in .net about 8 years ago. Things have changed soooo much since then.
I am wondering if its a license issue? Was also wondering if it had anything to do the testing hiccup, even though research is suggestion the two are unrelated.
I've described my actions as best as i could (without getting into ridiculous detail) and have included screen-shots of relevant stages of the process. Have a look and tell me your thoughts. Thanks.

The "Sys.Application is null or not an object" issue is known, submitted for a resolution and documented in KB #1528503. Unfortunately the KB search has been down the last couple of days...
However, the issue is limited to compile time and does not affect a completed application.
Re. the viewer missing. Sounds like the viewer directory did not get created or configure correctly. Before I get to that. You mention:
"I proceeded to try to browse to my app from another computer on my network."
This bring up the question: If you run the app right on the app server. e.g.; not a client computer, does the viewer and report come up? Is this issue isolated to client computers on the network?
I suspect that the issue exists irrespective of which computer you try to see the report from - but that is an assumption. If the assumption is correct, see [this|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/50aa68c0-82dd-2b10-42bf-e5502b45cd3a] article on configuring the viewer. The article does not have CR4VS2010 documented, but you should be able to guide your self using the article. I think the pattern will be obvious.

Fade out doesn't show when exported as a jepg sequence?

I'm exporting my video as a jpeg sequence because I can't get rid of the artifacts when exported as a .mov file no matter how much I mess with the settings. The Jpeg sequence works great the only problem is the fadeouts in the video don't show. Anyone know how to change that?
Or how to get the video to export as a .mov file without artifacts some other way besides changing the quicktime settings.

It still doesn't show. It's within the symbol, using the color effect alpha and doesn't show when playing through the timeline- only when testing the movie/scene or exported as a swf or mov file.

Pasted Content doesn't show up on Canvas or is at the very Edge of it

Since installing AI CC 2014 this Version but also my old CC Copy show the same weird Behaviour:
1. Copy an Element from the same or a different Layer via Ctrl-C
2. Paste via Ctrl-V on the same or other Layer - Content doesn't show up or is only pasted at the very Edge of the Canvas. I can see that even when the Paste was "invisible" the File has been changed (* Indicator on File Tab).
Yes, the Layers are all unlocked, so are the Elements.
Tried it in various Files.
I tried resetting Prefs. Nothing ...
Doesn't matter if I copy only one Element or a Group with many.
At the Moment my AI Installations are utterly useless.
Any Ideas?

I am suddenly unable to update or download apps on my iphone 3G. It says "the download will be available after you log in to itunes from your computer." I never had to do that before. Even when I do log in from the computer, it still doesn't work.

Even when I do log in from the computer, the download still doesn't work. So what's going on? Why would I need to go the computer to download an app to my phone? That defeats the whole purpose of having the phone, which is to do stuff when you are not at the computer!@!@ Any help greatly appreciated. Thanks.

Make a temporary, backup copy (if you don't already have a backup copy) of the library and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

When you go to the Google Maps app on the iPod does it correctly find your location? The iPod's locations service uses the location of the a nearby wifi router to locate te iPod. However, not all routers are in Apple's database and as of yet nobody here knows of a way to add routers to the database.

Can you increase the size of the photo that shows when you receive a call from a contact

Can you increase the size of the photo that shows when you receive a call from a contact ?

It used to be if you added the contacts photo on the iOS device they would have a large picture and if you added it from Address Book on OS X they would have a smaller thumbnail. However, since iOS5, all I've been able to get is the larger photo. Try adding the picture directly in the contacts app on your device. That should make it larger.

When I send a 5v from the DAQ, the voltmeter shows 5V, but when i connect a "normally open valve" from parker to the DAQ, the voltage automatically decreases to .14 V. It seems like it is being grounded. Why is this happening?

We are sending 5v to the DAQ using a voltage generator. We hook this up to a voltmeter and we see 5V. When we connect the voltage generator to a "normally open valve" from parker, the voltmeter shows .14V. It seems that when we connect both wires from the valve to the voltage generator, the wires are acting as a ground. We wish to control the voltage that flows to the valve through Labview. We checked the wires of the valve and they are working fine becuase if we send a constant 5V from the DAQ and grounded it, the voltmeter shows 5V. Does anyone know why the wires are acting as a ground and dropping the voltage to .14V?

Our DAQ is NI USB 6259. The valve only requires a max of 5V and our DAQ does provide up to 5V. However, after connecting the valve to the DAQ, the voltage drops to almost 0. We are assuming that the wires somehow act as a ground, but we are not sure if this is the case.
The issue here is not how much voltage the valve wants, it is the current the valve needs. The 6259 can only put out 5mA through an analog output. Your valve very likely needs a lot more than that. So you need to add in an amplifier circuit that can supply more current to operate your valve.
