After moving and resizing control, some controls don't redraw properly as the cursor passes over them.

I have a top-level VI with three panes (two splitters). One of the panes contains nested tab controls. One of the tab pages contains six XY-graphs, a table and some decorations.
I use a subVI to resize and relocate the tabs and contained controls. All this is working fine, and everything looks fine after the resizing is complete.
The problem is when the cursor passes over certain controls (the chart legends and the table column headers for example), they redraw with gray boxes. The problem only occurs after enlarging the window from its minimum size. It goes away if the window is resized back down to minimum.
Anything that causes the window to redraw, like another resize or minimize/restore, properly refreshes the screen.
Has anyone seen this problem, and have a workaround?
The problem exists in development environment or built in LV 9.01 or LV 2010.
Thanks!

Thanks again for taking a look at my problem.
force redraw - This is apparently only available in LV2010. I did give at a try, but it did not prevent the problem, nor did it correct the problem once the gray boxes appeared.
disable updates (on a graph) - This apparently only applies to 3-D graphs, which is not what I am using in this case.
disable front panel updates - I tried disabling updates before moving/resizing the front panel controls, then re-enabling updates afterwards. The problem is exactly the same as before. Once the move/resize is complete, passing the mouse over the table column headers or the graph plot legend results in the gray boxes.
I would appreciate any other suggestions you may have.
Again... the problem is not that the moving and resizing don't work. They work fine. But once the resizing is complete, passing the mouse over the legend or table column headers causes gray boxes to appear.
Thanks!

Moving and Resizing UIComponents

Hi,
I am making a flex application in which I am drawing Square,
Rectangle,Ellipse, line,etc with flex UIComponent.
I want to Moving and Resize the UIComponents .
And what would be a better way to put UIComponent on some
container and resize and move the container ? Or directly move and
resize the UIComponent ?
Can any one help me ??

Hello all,
regarding what I asked about, I've found this https://help.ubuntu.com/community/Resiz … Partitions
So the question now is about moving. If I dd sda5 to sda4 will I have to set something up for it work? Like some offsets/adresses?
If I am able to move sda5 to sda4, the rest will be fairly easy. Any about my partitiong layout - it's manual, I've used fdisk, cryptsetup, mkfs and the lvm tools that come with the arch install iso.
Also some have misunderstood - currently everything but the boot partition, which is on another drive, is encrypted - in one LUKS partition and inside it there is an LVM with the different partitions.
I've tested on a virtual machine by doing the following:
unmount partitions
move the luks partition by using dd with opts bs=4096 conv=notrunc,noerror,sync
after that follow https://help.ubuntu.com/community/Resiz … Partitions
Worked like a charm(if you need to remove mappers use dmsetup).
After that: the uuid's of the lvm's are the same so that's cool. Just need to get the UUID of the new luks partition and set it in grub's cryptroot parameter.
That's all
Still I think I will backup everything first, then I will try this.

Hi Ron.
Your Apple TV may have become paired with another remote. Hold the remote close to and pointed at the Apple TV, hold down the menu and Rewind buttons together for 6 seconds or until you see a broken chain icon on screen.

(1) Is there any way that I can get the transition menu to remain on the screen. I select a transition, drag it to the timeline and after I click done I have to start the process all over to perform this action on the next transition. I have premiere elements 12. In older version the menu would stay on the screen.
(2) In pan and zoom how can start zoom on a photo in the original picture and zoom in and the next picture zoom out and the next photo pan from right to left and the next photo pan left to right.
Thanks

What computer operating system is your Premiere Elements 12 running on? If you have not already, be sure to update 12 to 12.1, using an opened project's Help Menu/Update.
But to the immediate questions, assuming Windows 7, 8, or 8.1 64 bit....
1. No, it is what it is. But, are you applying the same transition each time? If so, then highlight/select all the clips involved (all at one time), then Timeline Menu/Apply Default Transition will do just that for the highlighted/selected clips.
To highlight/select more than one clip at a time, hold down the Shift key of the computer main keyboard and then click on each clip that you want in the group selection
or
with your mouse cursor draw a rectangle around the clips that you want to select
2. Are you using the Premiere Elements 12/12.1 Expert workspace Pan and Zoom Tool? Or the pan or zoom presets under fx Effects/Presets/? With those you can do pan or zoom, not pan and zoom.
Or, are you in the Elements Organizer 12 Slideshow Editor using the pan and zoom effect there? Or, are you using keyframing the Motion Scale property for zoom and the Motion Position property for pan?
Are you asking about photos with landscape or portrait orientation?
The pan and zoom tool does one photo at a time.
Have you read the Adobe documentation on the Pan and Zoom Tool?
http://help.adobe.com/en_US/premiereelements/using/WSeffff8bffc802084-494411db12fd35452dd- 8000.html
Please review and clarify and then we can get into greater details on this.
Thanks.

I am making a book and only have 23 pages done. I keep hitting the plus sign to add pages and no knew pages appear. Help

Assuming you have iPhoto 9 (11) give this a try: make a temporary, backup copy of the library if you don't already have one (Control-click on the library and select Duplicate from the contextual menu) and try the following:
1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
2 - Since only one option can be run at a time start with #3 followed by #4 and #1 as needed.
3 - try adding a page after each fix.

Why some fonts don't display properly

I use Windows 7, Pagemake 7 (with update 7.01)
Some fonts don't display properly in pagemaker file. Sometimes they look blank; sometimes display in part and the rest as blank. In fit-in Window view, sometimes a page displays properly, and next page is blank, go back to the previous page, it also turns blank. Some times letters look garbled. Display varies as and when the view size is changed.Example for the fonts - Souvenir LtBt . What could be the problem and what is the solution ?

Pagemaker is old software, it was designed for use when fonts were quite limited. It will only display the first 256 characters in a font. Modern fonts have moved way beyond this limitation. The solution is to stick with older fonts, or to upgrade to indesign. It does sound like your souvenir font could be corrupted, running font management software is a good practice no matter what program you use.

When I edit a contact's email address and then type the name in the Mail App, I see both the new and old address. Why don't I see only the new email address?

When I edit an email address in the Contacts App, and the type the Contact's name in the Mail App, I get both the old and new contacts. Why don't I get only the updated email address?

Mail remembers previously used email addresses for a period of time. Those you no longer use will eventually disappear. After you have sent one or two emails to the new address the old address will move below the new one. Then after a period of time not sending to the old address it will disappear. Patience is the key.

I have downloaded and used the iPod Reset Utility, alot that did. My current state is iTunes on my XP Home with SP3 sees the iPod. When I drag a song to the iPod, the Sync message appears for about 5 minutes, then the Apple symbol appears. But no song has been transferred to the iPod.
I tried to tap into the XP iTunes database from my iBook, but although it acted like it would add the XP library to the iBook library, it did not. I've got 19 Gs of songs on the XP. If I have to load each song from its original CD to get it on my iBook I'm going to start looking for some other app or device so that I can listen to my music.
It is a shame, in the old days, Apple techs use to look at what was going on, now it appears they don't, so they never know they have problems until Apple's profits fall.

Elements Organizer 8 - some WMV are not displayed properly in the Play Video but are in Play Vide

Hello:
Elements Organizer - some WMV are not displayed properly in the Play Video but are in Play Vide on Full screen. What's the problem? Wrong codec?

Because WMV's can contain a lot of flags, like DRM, they can exhibit odd behavior, indeed.
Usually, AV files will display in their native resolution, i.e. in their set Frame Size/Aspect Ratio and with their set PAR (Pixel Aspect Ratio), but sometimes those flags are missed, or are altered by other programs.
Remember, WMV's are designed to be streaming delivery-only, and are not intended, or designed to be edited. Most NLE's (Non Linear Editors) will allow them to be edited, but will require extra processing to do so. As is mentioned, WMM is designed around editing that delivery-only format, but most others are not.
There are many other formats/CODEC's, that ARE designed to be edited by the vast majority of NLE's, such as DV-AVI Type II's.
The best workflow is to NOT bring WMV's into the mix, unless one is using WMM exclusively. Converting those to an easily editable format/CODEC will always be the best course of action.
Good luck,
Hunt

Kerberos and Database control don't want to play

I've got a problem - it's been with Oracle support for over 2 weeks now and have had no reply.
Our infrastructure is 10.2.0.4 on Solaris. The requirement is having Kerberos enabled authentication for the database and management is via EM Database Control not Grid Control so each Database is managed individually and is self-contained.
Kerberos was installed and is working fine. You can get a ticket and login OK. What became obvious, however, that by enabling Kerberos, Database Control partially breaks. I know you can't have Kerberos EM accounts setup but that's not what we need to do.The agent just can not connect to the local database. I've done a bit of trouble-shooting and it's pretty obvious what the issue is but sorting it out is a bit of a problem.
Right, when you enable Kerberos, most of the settings are done in the sqlnet.ora file on the database server. The interesting setting here is the line :-
SQLNET.AUTHENTICATION_SERVICES= (BEQ,KERBEROS5)
Correct me if I'm right, but what this basically does is to say that any 'local' connections (eg sqlplus / as sysdba) just go in through the usual database/host group accounts (BEQ) whilst any other connections (sqlnet) go through Kerberos. This is where the problem looks as though it is. The EMAgent insists on using a full descriptor (host, port, sid etc..) and thus loops back through sqlnet and hits the Kerberos authentication brick wall and produces the standard Kerberos error :-
Thread-8 ERROR vpxoci: ORA-12638: Credential retrieval failed
vpxoci: Login 0xfdf08 failed, error=ORA-12638: Credential retrieval failed
TargetManager: Exception in computing dynamic properties of {db1.server1.acme.co.uk, oracle_database },SystemTablespaceNumber::ORA-12638: Credential retrieval failed
Thread-8 WARN vpxoci: OCI Error -- ErrorCode(12638): ORA-12638: Credential retrieval failed
The connect descriptor being used by the agent is :-
LOGIN = dbsnmp/<PW>@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=server1.acme.co.uk)(PORT=1521))(CONNECT_DATA=(SID=DB1)))
I've briefly edited the emoms.properties file to change the descriptor to IPC based and it still errors just the same. To duplicate this error we just created a normal database account "account1" identified internally and used these descriptors outside EM with sqlplus and it's just the same, so running :-
sqlplus account1/password@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=server1.acme.co.uk)(PORT=1521))(CONNECT_DATA=(SID=DB1)))
gives exactly the same credentials error and :-
# sqlplus account1/password
connects just fine. BTW, if you edit the original sqlnet.ora file and change (BEQ,KERBEROS5) to (BEQ) or even just remove the line, it all works fine but obviously disables Kerberos which isn't an option.
If someone has experienced this and knows a patch/fix or which configuration files to hand-edit I'd appreciate it.

(I wonder whether a discussion in the Grid Control forum might be useful as the GC folk hide out there ... http://forums.oracle.com/forums/category.jspa?categoryID=70)
I am curious about the above statement since Grid Control does allow individual 'administrators' to be isolated to specific systems/configurations. That functionality is implemented using EE's Virtual Private Database capability and seems pretty solid to me.
What goes wrong when you use the isolation capability in Grid Control?

Cropping when moving and resizing a cropping rectangle

I created a program that crops an image and displays the cropped image but I'm trying to add more functionality
by making it movable and resizable. The rectangle moves and resizes but it only crops an image when user draws the rectangle and not when moved or resized. I know that the X,Y, height and width position of the rectangle would need to be updated but I'm not
sure how I can accomplish this being new to WPF. Below is my user control "CropControl and the code behind. Also, I'm implementing my code using MVVM framework.

Hello HotSawz,
The ResizeThumb and MoveThumb is not in your code so I cannot compile. Anyway, it is not the problem.
Anyway, can you clarify more details about "it only crops an image when user draws the rectangle and not when moved or resized", it is already normal behavoir for you to draw a rectangle and then move it. What kind of action do you want? Do you
mean some controls like this:

Time capsule backup failure after moving and changing internet access

I bought a 1GB time capsule to backup my MacBook Pro using time machine and also archived files so I would have these when I had to move across country to work temporarily. The time capsule was working fine in my home after the original backup through an ATT DSL, but I then moved across country and set up a Comcast cable DSL and now Time machine records under Backing up: Preparing and the latest backup records failure. Is there a way of fixing this without erasing the entire Time Capsule and then taking 2-3 days of backing up again and will I have access to these when I return to my original home with the capsule and MacBook Pro. I have tried resetting all the backup modes and options.

Linda,
According to the logs, you are going to need to initiate a backup, and then let it do it's thing uninterrupted, perhaps all day of over night. Time Machine needs to do a "deep traversal". See this article.
*_Time Machine May Report "Preparing..." For a Long Time_*
First, it’s good to determine WHY Time Machine is "Preparing..." for an extended period of time. Examining the Console logs during this event can reveal what is actually going on behind the scenes. It may be “Preparing…” for a genuinely good reason. How long is 'too long' to wait for Time Machine to finish "Preparing..."? Some times, "Preparing..." is required to perform the normal housekeeping that Time Machine does periodically. Other times, it really is "stuck" and never proceeds after many hours.
*”Deep Traversal” (Recent Crash / Forced Restart / System Update / Extended Period Between Backups)*
According to the following KB article it can sometimes take quite a long time if Time Machine begins a “deep traversal” and has to compare data inventories. This may apply to your situation, particularly if many Gigs of data are involved. [http://support.apple.com/kb/TS1516]
You see, Time Machine *+does not+* ordinarily perform file-by-file comparisons to determine what has changed and thus determine what needs to be backed up. Rather, Time Machine relies on FSEvents notifications. This is a log that the system uses to keep track of changes to directories. Rather than scan tens of thousands of files for changes each time, Time Machine simply looks at this log and narrows its’ scan to only the directories that have experienced changes since the last backup. Otherwise, Time Machine would have to be running constantly just to catch every change on its own and thus eat up precious CPU.
Every event that FSEvents records has its’ own ID which includes a time stamp. At the end of every backup, Time Machine stores the last event ID that it processes. When the next backup is initiated, Time Machine looks at this stored ID and determines that it only needs to backup events that have occurred after the time stamp on this last event ID.
If, due to a system crash, power failure, forced restart, or some other major system event, Time Machine cannot find this last event ID in the system logs then it will consider the FSEvents log “untrustable” and it will go into what’s called “deep traversal”. The Console logs may report +“Event store UUIDs don't match”.+ In this event, Time Machine will by-pass the system log entirely and perform its’ own file-by-file comparison to determine what has changed since its’ last backup. Obviously, if tens or hundreds of Gigs are involved, then this process can take quite some time and should be allowed to proceed.
Additionally, it appears that if Time Machine has to go back too far to find the last event ID, then it will give up and simply go into “deep traversal” and do the file-by-file scan on its’ own. This can occur if Time Machine has not been able to perform its’ hourly backups for some time, as is the case for users who only backup once a week or so. This is also the case with major Mac OS system updates that change thousands of files at one time. There are simply too many events logged by the system for Time Machine to bother looking for the last known event ID.
Cheers!

After moving and resizing control, some controls don't redraw properly as the cursor passes over them.
