Blank page instead of the application home page.

Hello, I installed a 10g express edition database long time ago.
Everyting works fine up to now.
I made an application that we use in our company to report our activities.
The application is still working, I'm able to access the application home page and walk through it.
When I go to the apex home page: http://127.0.0.1/apex and I insert username and password for the "workspace" of my application, I see a blank page instead the normal one with the icons.
If I try to access the HR workspace everiting is ok.
Can you help me please?
Thank you, sofleo.

I found the solution but I have some doubts.
Last month I decided to export my application renaming it.
I don't remember if I modified the appication name changing it insiide the file generated by the export procedure or if there were some flags to be checked to export it with a different name.
So, examining FLOWS's tables I found a table in which the userid was the new application name instead of the original one.
How this is happened?
Did I launch for a mistake the sql file on the wrong databse (the file generated by the export).
My original idea was to export the application, rename it and install it on a new machine.
Any comment would be apprecciate.
Bye, sofleo

Thanks.

Hi Ron,
Try deleting this file.
com.apple.Preview.plist
/Users/YourName/Library/Preferences.
Drag that file from the Preferences folder to the Trash, emtpy the Trash and restart your Mac.
If that doesn't help, right or control click that image, then click Get Info.
In the Get Info window click Open with. You may have to click the discovery triangle.
Click the pop menu and select the application you want to open that image with... you may have to navigate to your Applications folder to make a selection.

Application messages are in the system log instead of the application log

Hi SAP GURUS.
The standard output is created from the outbound delivery .
All the messages are hitting the system log instead of the application log .
This is after the upgrade from 4.6c to ECC 6.0 .
Please provide the details how to move the log to the application log since the output is the standard output (SAP provided output type ).

Do these messages indicate a problem? If so what that could be problem and the solution?
Can this contribute to the sleep/wakeup problem when iMac won't wakeup after being put to sleep manually and not sleeping according to Power Saving settings?
Thanks a lot.

When I close a tab, why do I get a tabless blank screen instead of the view switching to one of the tabs that is open?

''locking this thread as duplicate, please continue at [https://support.mozilla.org/en-US/questions/1047350 /questions/1047350]''
Like the title says. I close a tab I'm done with, and I get a tabless white screen instead of it switching to a tab that's already there. I also get a blank page new tab along with previous ones when I start up firefox. Likely started after updating, but I can't be sure.

On the about:newtab page in the upper right hand corner, is there an option to change the blank page to Classic or another option?
Does this happen in Safe Mode? [[Troubleshoot Firefox issues using Safe Mode]]

Flash player 11 - blank space instead of the content

Hello,
Adobe Flash Player 11 is not working for me !
Here's some information about my laptop: HP G60 AMD Sempron 2.00 GHz Memory (RAM) 3,00 GB 32-bit operating system WINDOWS VISTA
My current browser: Mozilla Firefox 5, but pretty much the same thing happens with IE.
Adobe Flash Player 10 seems to be working for me, only there are some websites that require to update my version to view their content. When I do so (it says my installation is successful), I can't access flash content at all (instead I see blank space), nor can I see the picture that's saying which flash version I run (instead - blank space).
Can you please help me with this issue ? Thanks !

Did you mean Firefox 15 or 5? 15.01 is the latest release version.
When you install 11.4 (http://get.adobe.com/flashplayer) what do you see when you visit this page: http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html
If you just get white space, check Firefox's Add-ons page and click the Plugins tab. Do you see a listing for Shockwave Flash? If so, is it disabled or enabled? What version is reported?
Thanks,
Chris

How can I modify File Explorer to open This PC by default, instead of the new Home view?

The methods that worked in Windows 8.1 no longer work. I tried this method but all that did was mess-up the Home view...
http://superuser.com/questions/819521/how-to-make-windows-10-file-explorer-open-this-pc-by-default

Hi,
First, I have to say, I cannot get direct way to point the File explorer to This PC as in Windows 10. As an alternative method, we can delete some things in 'Home' and attach 'This Pc' into it via Registry key. Make it look like that we open This
PC.
1. Click Windows icon and type regedit in
Search box, and click Regedit to open Registry editor.
2. Right click to export this key for backup: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\
3. Click Windows icon and type Folder option in Search box, and click
Folder option to open it.
4. Under View tab, clear the checkbox Hidden extensions for known file types.
5. Copy following lines into Notepad, and save it as Fix.reg on Desktop.
Windows Registry Editor Version 5.00
[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\NameSpace\{1CF1260C-4DD0-4ebb-811F-33C572699FDE}]

6. Double click the fix.reg and Press Yes to apply the changes.
Open the File Explorer again, and you will see the Volumes under Home View

Can I encrypt my individual folders instead of the whole home folder?

I want to encrypt one specific folder only and not the whole folder especially since we don't really have (and use) multiple user accounts. How can I do that?

Use Disk Utility to create an encrypted disk image of that folder. Then delete all the files in the original folder. Next, option-drag all the files form the encrypted disk image into the original folder. Store the encrypted disk images somewhere where it won't get deleted and will get backed up. Now, any time you double-click one of those aliases, it will automatically ask you for your password, mount your disk image, and open your encrypted file.

Need help in Publishing the application URL

hi,
I am using Aoolication Express 3.0. I need to publish the URL of my application, so that both the database and application can be accessed from any computer using the URL.
Can anyone help me with that.
Thank you in advance.

I read yesterday (from the advanced tutorial documentation):
"You can determine the URL to your application by positioning the mouse over the RUN icon on the Application home page. The URL appears in the status bar at the bottom of the page."
It works.

Why do I receive a 'gear' icon instead of the Apple icon when starting up iPad2?

Hello all,
I searched the iPad community forums with no luck. My younger brother won an iPad2 at his 20th anniversary High School reunion, since he already had an iPad2 he suggested we give it as an Anniversary present to our parents. Since our parents are going to Italy this fall I thought it was a great idea as they will be able to use it as a resourse while traveling as well as keep us updated regarding their travels. (They have been amazed and curious at my iPhone 3GS and our iPads so we thought it would be great way to introduce them to a tablet.)
When they first turned on the iPad2 last night we received an image of what appears to be a gold/bronze mechanical gear instead of the familar Apple logo. Instead of the normal home screen we recieve the following screen. (http://i811.photobucket.com/albums/zz32/ScotchManGSO/ipad2screen.png) The home screen was initially fun to look at due to the pop culture references built into the icons. (Being a Star Wars fan the 'AT-AT' Walker icon was my favorite.)
Unfortunately the fun quickly wore off as we could not restore the iPad2 to the factory defaults using iTunes. (By the way, the iPad2 capactiy only indicated 11GB instead of 16GB.)
My best guess, although I just entered the world of Apple back in 2009 with my iphone purchase, is that the iPad does not have the iOS loaded. In moving through the applications it appears that the applications are designed to test the iPad display, charging, gryoscope, etc.
Any help in restoring the iPad2 to the normal home screen would be appreciated greatly!

What you have there is either a jailbroken unit with some crazy custom UI or an eastern knockoff. Give us some photos of the ipad itself, mainly the back and some experts can help.
If you plug it into iTunes does iTunes even acknowledge that an ipad is connected? If it does then try a restore.
Failing that, head down to an apple store and see what they can do for you.

Changing the application name that appears on the web browser

Hi All,
Thanks in advance for taking your time to reply to this question.
As a standard behavior, the WD application name in the project is displayed in the web browser the application is executed. How can i show a more user friend name instead of the application name which typically is more cryptic.
Eg: if my application name is TestWDApp, the title of the browser show TestWDApp when the application is run.
Cheers

Aha .. that worked!!! That was easy
Thanks a lot.

Hi,
Try the following steps:

2. Try the Microsoft Fix it in this kb to remove previous install completely:

This seems helpful on the issue.

How to display 2 level folder names in the application navigator?

We have our source code in the following structure.
C:\somefolder\project\java\all_the_java_code_under_this_folder
C:\somefolder\project\sample\java\all_the_sample_java_code_under_this_folder
In the project content, I select C:\somefolder\project folder so that the code under java folder and sample\java folder are picked up. But In the Application navigator, I would like to see the folder names (java or sample\java) so that I know which files I am working with. The package names could be the same, so I cannot identify files based on packages. The application navigator will display only the last part of the folder name (in this case, it is java). This is useless for me, because that part is the same as you can see from above.
Is there a work around for this problem, so that it is easier to navigate between files.

At the top of the application navigator play with the folder icon and with the number next to it, and see how they effect the display.
You can also try the system navigator as an alternative view instead of the application navigator.

Blank page instead of the application home page.
