Change Screen Resolution or not Change Screen Resolution?

I mean is it possible to change screen resolution with Java?
I read some topics (not in this forum) that is impossible. I know there is a method to set at full screen a frame with the favourite resolution but does it effectively exist a method to set the screen with a favourite resolution?
For example:
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setUndecorated(true);
        frame.setIgnoreRepaint(true);
        device.setFullScreenWindow(frame);
        if (displayMode != null && device.isDisplayChangeSupported()) {
            try {
                device.setDisplayMode(displayMode);
            } catch (IllegalArgumentException iae) {
                System.err.println("EX: " + iae);
        ...the device.setDisplayMode(displayMode) always throw me an exception: Invalid Display Mode (or something like that) with all permitted display modes (640by480, 800by600, 1024by768, etc...), with all permitted refresh rates, with all permitted color depths.
Illuminate me please!
Thanx in advance!

Bugs? playback resolution will not change?

The playback resolution will not change no matter what I choose ? it may be contributing to the distorted playback issues im having ? also when I select a clip from the project or media browser the sequence automatically starts in arri editing mode? I switch to dslr but the playback gets worse.

When you refer to playback resolution, do you mean the setting highlighted in this screenshot?
If so, what happens when you try to change the setting? And, of course, if that's not what you were referring to, please elaborate.
And when you say "when I select a clip from the project or media browser the sequence automatically starts in arri editing mode," are you referring to creating a sequence from the clip? If so, the editing mode generally doesn't matter much unless you plan to use "smart encoding" or to enable "Match Sequence Settings" or "Use Preview Files" when you export, neither of which is recommended in most cases. The main properties of the sequence settings that you want to make sure are right are the height, width, pixel aspect ratio, and frame rate.
As to the distorted playback issues, a screenshot might help to start troubleshooting that.
Finally, please specify exactly which version of Premiere you have--the three-part number like 2014.0.1, not simply CC or CS6.

HT5622 i have changed apple id will not change on itunes

changed apple id will not change on itunes

It is one or the other - an entirely new Apple ID or a change to the existing.
If an entirely new Apple ID, all apps include DRM protection that is tied to the Apple ID that was used to download the apps. You will need to use the former Apple ID and password to update apps that were downloaded with that Apple ID if an entirely new Apple ID was created.

Screen Size does not changes automatically

Hi,
I am developing on ADF BC, 10.1.3.2, on 17" monitor. Every thing looks fine on my system.
However, when I deploy the package on a 15" monitor, all screens does not fit within the explorer screen... Why ... Any settings is missing ....
Needs some help
Ravi Shankar Swamy

Hi,
Well, first think I did was this action. However, the client does not like that resolution, since you see very small fonts. Now, do I have to re-design every thing for the lower resolution or any settings exists to change globally ... windows.height and windows.width... or anything else.

Screen resolution does not change back after using a projector

Hi!
My office uses several different models of macbooks, but there is a small problem with all the Airs. When I have been using them with a projector I have to change back the screen resolution manually (go to the system settings and change resolution). On the macbook pros, however, the desktop restores themselves as soon as the projector is disconnected. It seems to me that this should be the standard behaviour of all macs, does anyone know why it is not working on the Airs?
Best regards
Erik

Hi Erik,
I had this problem on a MacBook and resolved it by recreating some plist files.
~/Library/Preferences/ByHost/com.apple.windowserver.xxxxxxxxxxxx.plist
~/Library/Preferences/ByHost/com.apple.preference.displays.xxxxxxxxx.plist
The xxxx's are your machine's EthernetID (MAC Address). I wouldn't delete, rather just move them to your Desktop and restart the computer. See if that resolves it.

When Matching Users Via Email, Changing Email Address Does Not Change Login

Well, the subject pretty much says it all, but here're some examples of what's going on:
Initial Data
- Create 2 Business Partners in SAP, C1 and C2.
- Create 2 Contact Employees in SAP, Adam with email adam at eden.org in C1 and Eve with no email in C2.
Synch
- Run Initial Synch followed by Standard Synch (for good measure).
- Web Tools gets user Adam with username adam at eden.org.
- Web Tools gets user Eve with username 2, the unique key for SAP's Contact Employee.
Data Change In SAP
- Adam's email is removed.
- Eve's email is populated with eve at eden.org.
Resynch
- Run Standard Synch.
- Web Tools changes both email addresses, with Adam's being erased and Eve's becoming eve at eden.org.
- Web Tools does not change the UserID, leaving Adam's as adam at eden.org and Eve's as 2.
That last bullet is the big problem: if a user changes an email address, the username doesn't change. Is there any way to change this across the board, or perhaps even force users to login via their current email address?

Also, there is a field in the Users table called EmailLogin. I have tried without success to change this field so that the user would use this field to login instead of the UserID, but have been unsuccessful in getting it to work.
As an alternative, the login control in /plugins/loginblock.ascx contains, as a portion, the following code:
    protected void loginMain_LoggedIn(object sender, EventArgs e) {
        NPUser user = new NPUser(loginMain.UserName);
        ((NPBasePage)Page).Login(user.UserID, user.AccountID, false);
Wouldn't it be simple to do the following?
    protected void GetUserIDFromDBByEmail(string email) {
        string userid;
        System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection();
        System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand(conn, "SELECT Users.UserID FROM Users WHERE Users.Email='" + email.Replace("'", "''") + "'");
        userid = (string)cmd.ExecuteScalar();
        cmd.Connection.Close();
        conn.Close();
    protected void loginMain_LoggedIn(object sender, EventArgs e) {
        string userid;
        // Though we're passing the "username" from the form,
        // we know that we're expecting the email to be in it
        userid = GetUserIDFromDBByEmail(loginMain.UserName);
        NPUser user = new NPUser(userid);
        ((NPBasePage)Page).Login(user.UserID, user.AccountID, false);
Again, the benefit to this is that you can synch using the Internal B1 Contact Code, which will remain constant and unique, and have the availability to change the way the user logs in by modifying the email address. Of course, email addresses would have to remain unique as well, but that's an easy enough thing to check for.

Changing cell padding does not change margin

The text in the cell of an existing table is clearly indented from the cell border. However, the cell padding is set to 0. When I change the cell padding to 10, 50, or any other number, the text margin does not change.
I am trying to create another table. The text in the new table is flush left. Whatever I set the cell padding to, the text margin does not change.
The documentation indicates that the only way to change the cell margins is to change cell padding. Obviously that does not work. How do I change the cell padding?
Thank you.
Cathy

Can you please anwser couple of queries to nail down the issue?
1) Please let us know the Contribute Version and OS you are using.
2) Is this happening with a particular page?
3) Can you try creating a new blank page, insert a table and modify the Cell Padding value.Check whether it is getting reflected and also verify the cell padding parameter is added in the code.
4) Previously if it worked and broken suddently, please try clearing the Contribute preference. Refer to the blog post, blogs.adobe.com/contribute/2011/11/launch-contribute-freshly-by-deleting-preferences.html

Resolution does not change after saving.

A previous answer does not help me. I save a file after changing size (inches) and resolution from default of 240ppi to 300ppi, when I reopen the file reverts to the original size. I use a Mac 10.6.8 Photoshop CS5 extended 12.0.4 x64.

If all you change is the document DPI resolution setting all the changes is print resolution and print size. The document size remains un-changed you sill have the same pixels you have before the resize. Only when you resample(interpolate) the number of pixels you have for the images does the the file size change. In fact you have a completely new image not a single old pixel exist all pixels have been interpolated to increase or decrease the number of pixels the image has.

L420 Screen Brightness does not change with Function Keys

I have installed the latest driers and since then I am unable to change the screen brightness using function keys. I have installed multiple driver updates hence it is difficult to find out which driver is causing the issue. Any pointers in this regards would be a good help.
Solved!
Go to Solution.

The newest Intel HD driver (from Intel) is causing this issue. Uninstall it and reinstall the driver provided from Lenovo.

After Disconnecting AirPlay Mirroring, my Ext. Display Resolution Does Not Change!

Im on Latest MBP 15, using Apple TV3 and DELL 27' Monitor as a main display.
When Im trying to play video via AirPlay + AppleTV as a Mirroring or Extended Display, it does change main resolution of my DELL ext. Display from 2K to 1080p... And after that I can return my native DELL resolution ONLY after Rebooting (even several times).
DELL is connected to MBP with mini D-port to D-port cable, ClickTronic (good and expensive one).
Is there any ideas how to fix that?
Thanks.

Sounds like an OSX issue... try posting to the appropriate Mac forum.

Resolution would not change on Satellite 5200-801

Hello.
I have always used 1280x1024 as a resolution on my 5200-801 laptop. For some strange reason, after the last reboot the resolution stayed at 1024x768 and the 1280x1024 is no longer listed as available (the maximum that I can see on the Control Panel display settings is 1024x768, either with 32bit colors or 16).
I tried to reinstall the NVidia driver but produced no result.
What can I do? The graphics card is a NVidia Geforce4 460 Go
Regards,
Pedro

Solved. On the Control Panel I did a "Scan for hardware changes". For some strange reason all display modes are now available.

VA02 Dataloss flag is set, when new screen fields are not changed, why ?

Hi,
I have added some new fields to the sales order item Additional data B tab.
When I go into the sales order in change mode (VA02) and navigate to the Additional data B tab and don't change any of the new field values, the system think that I have made changes to the sales order when I press the yellow exit button, I have debugged the transaction and field (SAPMV45B)R185D-DATALOSS is being populated, how can I stop this.
Any help will be appreciated.
Thanks
J-J

Hi Pascal,
I guess that the marked fields are the ones you are missing in bi.
"P" means that the values are extracted but one cannot restrict the values by using the parameter of an info package. Did you try to test the extraction with the rsa3 to see if the extraction locally works no your r/3 system?
If it works, check if the fields of the data source are contained within your transfer structure. If niot, add them and add the mapping to your targets.

Yann

Changing Apple ID does not change in all Apps

I recently (within the last year) changed my ISP and switched my email account. The old email was registered to my Apple ID and when I switched, I also changed the email to be my new Apple ID using "manage my apple id" online. This means that the Apple ID should be the same account, just a different name. There seemed to be no problems with this change on my iPhone and iTunes, but on my Macbook several applications are still looking for my old email for the Apple ID. These include iCloud and Messages.
I changed the Apple ID on my user in Users & Groups in System Preferences using the Change... option. I only have one user on the system and it is the Admin account. I can't find a way to change this in iCloud however. Messages isn't much of a problem, but more of an inconvenience. Every time I log in to my user account, the Messages dialog pops up asking me to sign in with the password to my Apple ID and displays the old one. I just cancel out of this. In the Messages application however, I have removed the old account and added the new one and I am able to send and receive messages using it.
Why are these apps still asking me for my old Apple ID when my Admin Apple ID is my new one?

Hi,
iCloud and the iMessages servers are effectively independent of the others.
You can in fact use different IDs for iTunes, iCloud and iMessages.
Start with System Preferences > iCloud.
There is no setting in here for enabling Messages (i.e. it has no links with any form account there).
Use the Sign Out button to disable the current Apple ID and then add the new one.
Do the same in Messages > Preferences > Accounts for the iMessages account.
As you have Mountain Lion use the Details Button then the Sign Out one in the next pane.
I have two of my several Apple IDs listed in th Users and Groups pane but it also is deactivated as regard to changing password resets.
You can alos use an Apple issued email ID as A Valid AIM screen name in Messages (Add under AIM/AOL depending on version)
This means @mac.com and iCloud issued @me.com and @icloud.com can be used as AIM Screen Names.
This may mean you can have it as the iMessages ID and as a Screen name.
