Cannot see the application window when the program is run

I wrote a java GUI using Jbuilder. I cant see the application window when i run the program. THe program compiles successfully but the application window pops up only showing the blue title bar and minimize maximaize and x out icon on it. I done see my GUI or anything below the 1 inch long blue title bar. Can someone plese tell me what i am doing wrong. Thanks.

A quick look-up in the API confirms that pack is not deprecated. Setting the size of the window to a specific size is quite a bit different than what pack accomplishes. Pack determines the preferred size of all of the components, lays out the layout manager and then sets the size of the window based on the size of the components inside of it. Calling setSize, however, will force the window to be a specific size no matter what the components want and thus creates a window that is probably not the right size for the components inside of it.

How do I size the iTunes windows when the window goes below the bottom of the screen? Can't reach controls or items at bottom of list.

I can't access items at bottom, or scroll to them. Full Screen gets around the issue, but I don't like full screen.f

Firefox no longer opens PDF files. Explorer works OK. I have checked the Applications window in the Tools/Options and it says I am using PDF-xChange viewer....It just does not do anything. I get the message in the Download Error window which says...."could not be saved, because you cannot change the contents of that folder. Is the same error which I get when I attempt to open a PDF file on a webpage using the Firefox browser....Explorer works OK so I am now forced to Explorer to read PDF files via a browser.
== This happened ==
Every time Firefox opened
== After removing a old copy of PDF-xChange Viewer and updating to the last version

The error message suggests that the file (pdf) that you're trying to download cannot be saved in the folder Firefox tries to save it in.
This can be due to several things - it could be a non-existing folder (could be a problem with the updated application), the hard drive could be too full to store the file (less likely if you can generally surf the net without error messages) or it could contain an error.
To complicate things a little further, it seems to me that you have (at least) 3 different PDF-handling plugins in Firefox from different programs:
PDF-XChange Viewer Netscape Gecko Plugin
Adobe PDF Plug-In For Firefox and Netscape "9.3.2"
Zeon PDF Plugin For Mozilla
This shouldn't matter too much, thou, as it will most likely simply use either the latest installed or the first one it finds when looking up associations for files of type 'pdf'.
First, in Tools > Options... > tab General > section File download, select "Save files in" and Browse your way to a (non-writeprotected!) folder on a drive where you're certain there is enough free space - like the Desktop folder to make the files end up on your Windows desktop.
Second, under Applications as you mention yourself, find all document types related to PDF files, and set these to one of the programs. Check the entire list to be sure there isn't one hiding under one of the other programs' document types (Adobe Acrobat document, PDF X-Change and Zeon).
Restart Firefox, and try opening a PDF again.
If it fails once more, try changing the documents again to one of the other programs, like "Use Adobe Acrobat (in Firefox)".
If it STILL fails, change it to simply "Save file". Then you can simply browse your way to the download folder with Windows Explorer, and doubleclick the PDF file to see which program actually handles PDF files as default on the machine, and if it works properly.
If Firefox flatly refuses to save the PDF files in a folder which you're certain both exist and has space for the file, some (probably security related) program is most likely interfering with Firefox, preventing it in storing PDF files on the system.

When I start my MAC Pro (OSX10.6.7), It always opens the Application window. How do I prevent that from happening? I just want to see the desktop

Everytime I start my MAC, the Applications window opens. How do I prevent that from happening. I just want to see the Desktop with the normal Hardrives and folders I setup on the Desktop.

Start up. Close the offending finder window. Shut down.
Now start up again.
Is it fixed?

Just updated firefox. While trying to run it show error message : "The application or DLL C:\Program Files\Mozilla Firefox\sqlite3.dll is not a valid Windows image.

Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can skip the step to create a new profile, that is not necessary for this issue.

Cannot print a pdf file when the pdf file is opened in another window

Running FF8.0 I cannot print a pdf file when the file is contained in a separate window opened by the appl (not just another tab). Options -> options -> applications all point to Use Adobe Applications in Firefox. I've had this problem in 7.0, 6.0, etc but I believe I was finally able to print these external browser/adobe windows somehow. Printing a pdf file shouldn't be that tough. When I run into this situation, file can be printed from the external window by IE.

Check the document properties (Security) for this file in Adobe Reader; perhaps printing is not allowed?

Is there a setting to wrap code when resizing the application window?

I find it very annoying that I have to scroll horizontally to get to specific areas of my code. Is there some sort of preference that I can set to wrap my code so that it wouldn't extend past the visible area of the application window? Thanks.

It's June 16 and no word wrap. Maybe there was word wrap. When I downloaded Edge Code, I immediately started installing some brackets plugins. Could one of them eliminated word wrap?
Speaking of brackets plugins, it's hard to know whether one is or isn't compatible with Edge Code. Of the ones I installed, none of them has prompted Edge Code to warn me of anything, however, some of them seem to work and some of them appear in the interface but don't seem to work, and some of them just aren't there at all.
Perhaps I need a cheat sheet like with brackets so I know what magical key combination will make something work or reveal something hidden?
Anyway, support for plugins needs to be clarified. If there are going to be plugins, there needs to be a pluins manager (the one from brackets doesn't work).
But I was mentioning Word Wrap... Is that part of the current build and I destroyed it with a plugin?

How can I change it when I cannot view it on my account. I am not even sure how this got setup.

If you mean your rescue email address, it's in the Passwords and Security section, after you answer the two security questions.

I am trying to import aperture library from macbook to new imac the import window sees the external harddrive but does nt see library. I can open library as a refernce library but cannot import onto hardrive as managable files

I may be misreading what you are trying to do but you don't import libraries via the import window. You use File->Import->Library..
If this doesn't resolve your problem post back with more detail of what you are doing and what is happening.

Premiere Pro cc won't launch. When I try, the application window flashes, then the application exits without an error message.

I downloaded trial versions of Photoshop and Premiere Pro on my brand new MacBook Pro 15" retina 2.8GHz Intel Core i7. OS X 10.9.5
Photoshop works perfectly. When I try to open Premiere, the application icon on the dock flashes and then disappears without an error message. I have tried (several times) to sign out and in again to Creative Cloud. I have also uninstalled and reinstalled Premiere Pro. The same thing continues to happen.
Any suggestions? I'm extremely frustrated as my old version of Final Cut doesn't work on this OS, and I'm keen to try out Premiere before I commit to buying (renting) it.
Thanks, Team.

Somekind of hardware incompatibility probably. Tech support will work through install/launch failures probelms with you for no charge if you call/chat them.
Having CS5 installed or uninstalled shoudl have nothing to do with it, both apps can run live on the same system simultaneously.

Can't see the Firefox window when it starts.

Running Windows 7 home edition. On opening Firefox, the window appears to try to open to the right of the screen. There is no window visible apart from the small preview in the task bar. Consequently, I can't drag, click on or access any of the options. This happened after installing Silverlight which has now been deleted. Firefox has also been deleted and reinstalled. Any ideas?

I managed to solve things by getting it to open in 640 x 480 and then restoring a previous version. There was no way to drag, move or bring the window back to the screen that I could find. Apparently an update was released to fix the problem of the screen wandering off. I didn't have that problem but the update automatically installed and disappeared the Firefox window off the screen. It was only Firefox that had the problem.

Cannot Start Microsoft Outlook. Cannot open the Outlook Window. The set fo folders cannot be opened. You must connect to Microsoft Exchange with the current profil

Cannot Start Microsoft Outlook. Cannot open the Outlook Window. The set fo folders cannot be opened. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost)
OK. This is a new outlook setup on a laptop. The mail account is on a MS Exchange Server 2010. The user can log on to their laptop no problem with their AD login and password. To setup the outlook profile we have checked the name OK. When we click finish
and try to start outlook we get the above error message. It is driving me pots as I have tried also of things. I have tried to connect without catching the files. The error message then says that the Exchange Server is down, yet we checked the name OK and
I can log on to the MS Exchange server and see the setup.
What else is it that I need to look at as I have tried everything. I will add that they one service I see not running is the Exchange RPC service. If I try to start it, it fails saying Some services stop automatically if they are not in use by other services
or programs.
What can I do?

The major cause of this problem is a corrupted Navigation Pane settings file – profilename.xml, where “profilename” is the name of your Outlook profile. A good sign that the
file is corrupted is when the size of the file is shown 0 KB. No one knows the precise reason why this takes place, but all versions of Outlook from 2003 to 2013 may get affected.
Other causes may be when you run Outlook in the compatibility mode, or if you are using a profile generated in an older Outlook version, or if the Outlook data file (.pst or .ost)
was removed or damaged as the result of faulty uninstallation or reinstallation of MS Outlook.
Follow the steps given below to resolve this problem
1. Recover Navigation Pane configuration file
2. Repair your Outlook PST file using Inbox Repair tool
3. Create a new Outlook profil and import data from the old PST file
4. Turn off Compatibility Mode
5. Start Outlook in Safe Mode

I have been trying to move pictures to iphoto and am now receiving a message that "you cannot open the application iphoto because the classic environment is no longer supported.

I have been trying to move pictures into iphoto and am now receiving a message the say I "cannot open the application iphoto because the classic environment is no longer supported."

Launch iPhoto the the Option key held down and create a new library. See if you can import those photos into it. If you can then your current library is damaged.
If that's the case make a temporary, duplicate copy of the library and try the three fixes below in order as needed:
Fix #1
delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your Home/Library/Preferences folder.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding the the Option key. You'll also have to reset the iPhoto's various preferences.
2. delete iPhoto's cache files that are located in the Home/Library/Caches/com.apple.iPhoto folder.
Fix #2
Launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library. Select last three options.
Fix #3
Use iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your User/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.
