How do executables find their data

I've been using linux for a few months now, but I have yet to figure out something that has been nagging at me the whole time: How do binaries find their associated data? Take a game, for instance. Where the binary is located in /usr/bin but the graphics and sound data are located in /usr/share. What exactly is the process that the system uses in order to connect the executable with the data its requesting?
Does the application have to request it directly, such as: openfile("/usr/share/game/sprite.png")?
Or if the application says openfile("spirte.png") to the operating system, does the operating system automatically look in the /usr/share/game directory for the data? If so, is there a config file somewhere to specify what that directory is if the distribution wants to use something other than /usr/share to store application data?

Yeah this is the kind of thing where as a programmer you really feel like you shouldn't be having to do it, but at the same time there isn't an easy solution which would work everywhere. You just want to say "give me my data! Find it! Find it now!" and have some lackey-function magically retrieve what you need, but alas...
The harsh reality of the situation is that programming really can be this boring!

How do I find the date and time stamp on pictures?

How do I find the date and time stamp for my pictures?

The Photos app will not do this but other apps will. iPhoto has an icon that when tapped with the photo open will show the EXIF information you are looking for. iPhoto is not free but you can purchase it in the App Store.
There may be other photo apps that provide this information as well.
PhotoForge2 will show the EXIF data as well as the GPS data if it is available.

I HAVE OLD iPHONES BACKED UP. how do i find the data and recover or delete dups and junk

You can't see the data inside the backup, and you can't restore just part of the data if that's what you're asking. To see the data you have to restore the entire backup.

How do I find migrated data on Mac Mini

I have migrated data from windows to new Mac mini. Now I am not finding iTunes music transfer over and email did not setup. How can I find this data and import into iTunes and mail?

Open the Users folder on the internal drive, move one account's home folder to the other account's desktop, and retrieve the files from there.

How can I find a data base table containing a GUID, which is result of the macro's execution?

Hello,
please help me to understand how the macros work. I am facing database inconsistency. The CRM-system retrieves a GUID of an opportunity’s item and checks its existence. However, this GUID (here it is es_info-ref_object) does not exist. As result, an exception is triggered.
I am trying to figure out which data base table is responsible for the inconsistent data. Instead of SELECT statement, I see in the debugger that a macro retrieves the “guilty” entry .
macro_execute macro_msg_data_read_rea.
My Question: How can I find a data base table containing a GUID, which is result of the macro’s execution?
Thanks a lot

When you save a PDF out of Distiller it doesn't just have different options, it's an entirely different program. It doesn't do things the same way, so it can't have the same options. Saving from Distiller is in many ways better, expecially in that transparency isn't flattened.
What specific options are you looking for?

I downloaded a file of 46MB, but that is not in Network Pane in Activity Monitor. How can I find download data history?
Is there any application that can monitor all download and upload data, history etc.

telling me to buy a new router is NOT a solution.
And why not? Apple is selling these things like BigMacs. They can't make enough of them. You've been suffering since May because you refuse to get a decent router.
Can you imagine if a company that makes a refrigerator told me that I needed to upgrade my electrical system to rectify a problem with their device? What kind of response IS that?!?!
What if the problem with their device is that it requires a new-fangled "grounded" outlet and your circa 1890 house doesn't have grounded outlets. Would you refuse to purchase a $ 25 adapter on principle?

How can we find out data in an editable ALV grid has been changed or not?

Hi Experts,
How can we find out whether a data in an editable ALV grid has been changed or not.
I am using the
FM -> REUSE_ALV_GRID_DISPLAY_LVC
for ALV display.
I have to chekc whther data has been changed or not befor saving. if changed then only i want to
SAVE
. I cannot use the internal table comparison method for this purpose also i am not using OOP ALV.
So kindly sugest me an alternative.
Thanks and Regards,
Shahana

Hi,
Thanks for your answer. I already saw this post.
See this method.
CALL METHOD reuse_alv_grid->check_changed_data
IMPORTING
e_valid = lv_check.
This will update the internal table with the edited values. Then we can go for internal table comparison.
But my scenario will not allow me for itab comparisons.I just want to know the ALV data has been changed or not.
Regards,
Shahana

How do I find the date of download?

I am trying to find the date that an app was downloaded. I have all the apps my kids (teenagers so parental controls are not the avenue I am looking for) download automatically download to my devices so I can keep track of what they are doing and I want to see the date one of the apps was downloaded. I'd also love to be able to see which device downloaded which app. Any chance of that?

If I log into my account via the Store > View Account menu option on my computer's iTunes and then click on the 'See All >' link to the right of the Purchase History line, I then get a screen with my most recent purchase at the top of the screen, and below that a list of older purchases including their order date, order number, items in the order and the total price
e.g.
Clicking on the little arrow to the left of the line will expand it. Do you not get that screen ?

Your forms mode isn't clear. Is it in enter-query mode or insert mode.
what can you do ?
use a timer in post-change or when-validate-item trigger at deptno item at first data block. because go_block isn't supported by p-c or w-v-t trigger.
and at when timer expire, write your code to go second block and insert/query the associate date from emp table.
Hope you understand.

How do I find the date

I've never done this before. Can anybody see my question (that I typed before being taken to several different screens for various passwords & othe BS)? I'm trying to find out how I can see the date & time a photo was taken on my iPhoto. Can't find it anywhere in my phone. The date stamp I've managed to find in iMovie when I try to "adjust time & date" is clearly WRONG (unless every photo I've taken has been at 2:22 am)--don't get how a phone with GPS can't get a correct time stamp. Tried looking in my iPhone calendar, but all my entries prior to this month appear to DELETE automatically--another awesome feature.

Select the photo and type Command + i to open the Info trat at the right. The capture date of the photo willl be listed near the top under the file name.
