How to kill an alv-grid object and refresh the frontend
Hello experts,
i have created an alv-grid display!
now i want to hide the whole alv-table on the screen when user e.g. hits a button!
How can i kill this object and refresh the frontend?
Thanks a lot,
Marcel
Hello Marcel
For this requirement I would use the following approach:
(1) main screen '0100': here you display your ALV grid
(2) Define a dummy screen '0101' the user will never see
(3) Link the container for the ALV grid (e.g. go_docking) to the dummy screen when the user pushes the HIDE button (method LINK)
(4) Link the container back to your main screen when the user pushes the DISPLAY button
I never ever destroy a grid control and re-build it from scratch but always use either of its methods REFRESH_TABLE_DISPLAY or SET_TABLE_FOR_FIRST_DISPLAY.
Regards
Uwe

ALV OO and refreshing the ALV grid
Hi,
i have some problems with my ALV 00 program.
On screen 1 i have to fill in a material number.
For that material i'm getting some data and show in screen 2 in a ALV grid.
Via BACK-button i'm getting back to screen 1 and can fill in another material number.
But the 2nd (and 3rd, etc) time i fill a material, the ALV grid data from material 1 is shown. Even if the internal table I_ALV where the data is, is changed.
What should i do ?
I have initialized the customer container and the grid, but that didn't solved the problem.
regards,
HansHi,
Try clearing and refreshing the alv grid data table in screen 2.
Check with this code. this code is working fine. If we go back and change the input, it is showing the output corresponding to the second input only.
Have you use this method?

ALV Grid with size of the whole screen
I need to create ALV Grid, that fits any screen. How can i do this?
I tried cl_gui_docing_container, but in the constructor it's possible to make it to occupy only 95% of the screen.If you are using a custom control on the screen and then a custom container you can easily do this.
Create a screen(Size 200 x 240), place a custom control on the screen and make it to the max size 200 x 240. Now in the attributes of the custom control, check the Resizing option for both horizontal and vertical, with some minimum numbers there.
Now, your ALV grid automatically occupies all the space available on the screen irrespective of the size if the screen and you will have only one scroll bar.

How can I start anew with Photos and clear the (minimal) stuff it has uploaded
I've about had it up to here with this new Photos scheme. I reorganised my Aperture libraries on both my iMac and MBA in preparation for this, delayed turning Photos on for a couple of days until I thought everything was ready based upon the limited advice that was out there, and then got stuck in an endless loop of "uploading" and "preparing" every time I opened Photos. There are 19,975 images in my Aperture library on the iMac. I was stuck at Uploading at anywhere between that number and 19,000 with no progress after hours of waiting. I tried all the tricks mentioned here including re booting, restarting the app, repairing/rebuilding the database, killing the "cloudd" process, etc.today Today when I restarted Photos, it now said I had 23,775 images to upload- 4000
more than I have-and of course it got stuck there, like it has for the last week.
I copied the previous Aperture library (pre Photos migration)back to my iMac and opened it in Aperture. Thankfully, all the photos I had taken on my iPhone this week during this Photos clusterphuck transition were in the Aperture Stream so I didn't lose any of those. I'm willing to give this whole thing one more shot. So i need some advice. How can I start anew with Photos and clear the (minimal) stuff it has uploaded (about 6000 of 19,000 images in the last 7 days) ? If I simply delete the Photos.photolibrary file will that do the trick and lt me start a new fresh library using?

It is hard to say from your post, why the migration did not succeed in your case.
by "stuck on upload" do you mean, you opened the Aperture library in Photos, and Photos converted it to a Photo Library, and then the upload to iCloud Photo Library did hang? Or did already the upgrade to the Photo Library fail?
If you want the Aperture library to upload to iCloud Photo Library, it needs to be on a disk formatted MacOS Extended (Journaled) and the original image files must not be referenced. Referenced originals will not upload.
Also, the upload may hang, if you do not have enough free iCloud storage, orr if one of the videos or photos in your library is in an unsupported format or corrupted.
To start over, try to repair and rebuild the Aperture library before opening it in Photos. Try all Aperture Library First Aid options - starting with repairing the permissions. (Repairing and Rebuilding Your Aperture Library: Aperture 3 User Manual)
If I simply delete the Photos.photolibrary file will that do the trick and lt me start a new fresh library using?
You will have to delete the photos that are already in icloud too; otherwise you are risking duplicates.
Can you launch Photos at all? If yes, delete all photos in Photos and empty the Recently Deleted album. Wait for the deletion to sync to iCloud. Then delete the Photos.photolibrary. -
Creating remote objects and passing the retrieved data to modules
I found at this Adobe tutorial a nice "RemoteService" class that creates a RemoteObject and contains the functions for handling the result and fault events. If I wanted to use this approach, how could I pass the data from the result handler to interfaces that modules from the main application could use?
I could put the RemoteService/RemoteObject in the modules, but (in my opinion- and I could be wrong) the best design seems to be using the remote calls in the main app and passing the data along to the modules.
Ultimately, I would like to know what the "best practices" are for creating remote objects and passing the retrieved data to modules
Thanks!public void mouseClicked(MouseEvent e) {
X x = new X(e.getX(), e.getY());
}I don't see the difficulty. -

I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?
It's almost impossible. The new iMacs have a Target Display Mode, but it's built to do that. Without ripping your screen out, finding an acceptable power supply, frame, and whatever electronics to convert a Thunderbolt signal to the screen, the cost will be much larger than buying a cheaper HiDef monitor that runs with an HDMI to Thunderbolt cable to your MacBook 15. In fact, you can sell your 17" MBP for a lot of money, unless it's broken or something, buying you a really sweet monitor.
By the way, I found your answer by searching this forum. I would suggest using the search function here in the futuere. -
I was trying to make a new screen recording using quicktimeplay, but when I watched the video after recording it all I could hear was me talking while the video was showing on the screen. How do I turn off that recording and turn the right one on? thanks
Hi j2399123,
It sounds like your screen recording is doing what it was designed to do, capture what is happening on your screen, with optional voice over with the microphone.
Screen recording is for recording what you see on the screen, it is not a "video capture" option, like for capturing a movie with sound that is playing on your screen.
For the QuickTime recording options, check out "Recording with QuickTime Player" in
Mac Basics: QuickTime Player creates, plays, edits, and shares video and audio files
http://support.apple.com/kb/ht4024
And for screen recording specifically, there's
QuickTime Player 10.x: Record your computer’s screen
http://support.apple.com/kb/PH5882
Thank you for thinking of Apple Support Communities for your support needs.

How do you move a single album, and not the whole library, in iPhoto to an external hard drive?
How do you move a single album, and not the whole library, in iPhoto to an external hard drive?
File -> Export to a folder and copy it over.
That will give you a folder with the images. There is no way to move an album outside of iPhoto. You would need to have a library containing it.
