First event

what is the first event that trigger in an abap program and what is the order of other events which usually trigger in an report

First event -
Initialization : triggered when the report is loaded in memory.
At selection-screen output : triggered when the selection screen is loaded in memory before being displayed.
At selection-screen : before leaving the selection screen.
start-of-selection : the first event for displaying the report.
This event keyword defines an event block whose event is triggered by the ABAP runtime environment
when calling the executable program selection screen processing of a selection screen.
In an executable program, all statements that are not declarations,
and are listed before the first explicit processing block, are assigned to this event block.
If the program does not contain an explicitly defined event block START-OF-SELECTION,
these statements form the complete event block START-OF-SELECTION.
If a program contains an explicitly defined event block START-OF-SELECTION,
these statements are added to the beginning of the event block.
If the program contains no explicitly defined event blocks,
these statements form the entire event block START-OF-SELECTION.
end-of-selection : after the start-of-selection is completed.
classiscal report events.
top-of-page : every time a new page is started in the list.
end-of-page : every time the list data reaches the footer region of the page.
interactive report events.
top of page during line selection : top of page event for secondary list.
at line-selection : evey time user dbl-clicks(F2) on the list data.
at pF<key> : function key from F5 to F12 to perform interactive action on the list.
at user-command

First event fired to event structure

Hi all,
Does anyone know what's the first event being fired to the event structure on VI startup? I set a breakpoint on the event structure and it breaks. However i wasn't able to capture whats the event.
My intention was simple; i have a table which list all the IO names and values. So during VI startup, i wan to populate the IO names first. Then in a timed-loop, the values are updated respectively. In this case, i don't need to "refresh" the table every time which waste time and resources.
It something like the OnLoad event.
Another way out is to register an user event, and have this event fired during application startup. But i wonder if anyone has a better way?
Many thanks!

Why don't you show us some code.
Are the IO name static for the duration of the program? Are you using a regular table column or the "row header strings []" property for the IO names?
If you want to write the row headers at the start of the program, place the code before the main loop containing the event structure. No event case needed. If you have a specific event to update the table headers if needed, fire the event once at startup using a signaling value property, again with the property node placed before the main loop.

Which is first event triggred in interactive report

pls let me know

<b>The event are triggered depended on the way the output is generated . </b>
for eg:
"Initialization :

"At selection-screen output :
triggered when the selection screen is loaded in memory before being displayed.
"At selection-screen / <field> :
before leaving the selection screen.
"start-of-selection :
the first event for displaying the report.
"end-of-selection :
after the start-of-selection is completed.
"classiscal report events.

Can u please tell me events trigaring and first event in report

hi experts,
can u please tell me events trigaring and first event in report

actually first event triggering in a report is intialization
but before that there is one more event get triggered that is load of program.....This is the very first event which is trigger in a report program. Really I have never needed a reason to use this. But I would assume that it can be used when you want to do something before the INITIALIZATION event.
Classical Reports can have these events, in the given order :
initialization
at selection-screen
start-of-selection
end-of-selection
top-of-page
end-of-page
In addition o the above, the following events are possible in case of Interactive Reports -
at line-selection
at user-command
at PFnn.

Event Structure Freezes Vi After Capturing The First Event

My Event structure catches the first instance of my button press but then it freezes my Vi. The reason is because of the while loop but I need the while loop to constantly read from a serial port and send data to a serial port. The vi included is stripped down to be just a while loop that does nothing. I have also tryed putting the event structure in the while loop, but the same thing is happening.
Any ideas?
Thanks,

Also, put the button inside the event structure where it is acted upon, from LV help (suggest you read the entire events section of help):
When you trigger an event on a Boolean control configured with a latching mechanical action, the Boolean control does not reset to its default value until the block diagram reads the terminal on the Boolean control. You must read the terminal inside the event case for the mechanical action to work correctly. As a reminder, a note appears in the Edit Events dialog box when you configure a Value Change event on a latched Boolean control.
Refer to the Handling a Latched Stop Boolean Control in an Event Structure caveat for information about how to handle a latched Boolean control.

Recent - First event you see how do you change that.

I notice that under the "Recent Foldable Tab" the first item is an event. In my case this event is 2002 event and I'm wondering under which criterea that event is shown there and I how I can change that?

I just figured it out, If you click Show Photos in the Events Library section then that Recent Event item gets updated

Syncing ical to Entourage -- only first event syncs!

Hi. I set up Entourage to sync with iCal. This created an Entourage calendar in iCal, so far so good. I created a new event in iCal and put it in the Entourage calendar. Go over to Entourage and it has synced up nicely. Great so far.
Then I go back to iCal and change all my stuff over to the Entourage calendar. Go back to Entourage. Nothing. I go to the Calendar pull-down and select SyncNow. Nothing. The one event that synced ok before is still there, but nothing else. I go back to iCal and create new events and these wont sync.
What happened?! Help!
Thanks.

Can you give a bit more information about what you've done? When you say you have gone back to iCal and changed all your stuff to the Entourage calendar, do you mean that you changed individual events to the Entourage calendar in iCal. Does that mean this is the only calendar left in iCal?
If so, then my suggestion is:
1) back up your iCal calendar - File, Back up iCal
2) ensure the calendar name in iCal is "Entourage"
3) go to Entourage preferences and untick "synchronise events & tasks with iCal"
4) quit Entourage, open Entourage and tick "synchronise events & tasks with iCal" again
5) you will be asked before it syncs how you wish the sync to occur and you should select to have iCal override Entourage.
If I'm right you should end up with a calendar in the Entourage application which reflects your Entourage calendar in iCal.

First event, then project missing

I have search the web to find answers for this question, and it seems may people have similar problems, but I cannot find an answers. Hope somebody here can help.
After opening iMovie, I noticed one of my events was empty. The file was stil present in the iMovie event folder, but did not show in the event. I found a solution where I had to change something in the source code, I think the plist file. I saw there that it reffered to a .mov file, however the source was a .dv file. After changing it (with txteditor) and opening again now the project using the event (which was showing triangels befor) was now gone. Stil present in the folder, but not in iMovie itself.
I opened the package of the project and change the 'project' file in txteditor also, because this also reffered to the .mov file, not a .dv file. But I have not been able to repair either the event or the project.
Can somebody help?

Update: moving my event to an external harddrive (using iMovie) has solved the problem with the event. The event even shows (by underlining) which clips I used in the project. However the project still does not show, is missing.

Taking action only the first time an event executes

I want a certain action to occur only the first time an event handler for a button is called. Is there a simple way to do this?
Bill F

There are two pretty easy ways to do this.
If you want to continue to trap other events (other event cases in your event structure), use a shift register:
1. Add a shift register to the loop containing your event structure. (right-click on the left-hand border of your loop and select Add Shift Register).
2. Wire a numeric constant = 0 from outside the loop to the input (left-hand) terminal of your shift register.
3. Inside your event structure, in the event case you want to handle only once, put a case structure around the code you want to execute only once. That code should be within the True case.
4. Add an Equal To 0? function (from the comparison palette) to the loop. Wire the input shift register to the input of Equal To 0?. Wire the output of Equal To 0? t
o the selctor for your new case.
5. Within the True case of your new case structure, add a numeric constant = 1. Wire that constant out to the output (right-hand) side of your shift register.
6. Within the False case of your new case structure, wire the input side of your shift register to the output tunnel created by the wiring in step 5.
This way the event structure will keep running and handling other events, but the case you just modified will only run the first time: the first time you get the event, the shift register will = 0 so you'll execute the True case of your new case structure. Within that case, you set the shift register to 1. The next time you get that event, the shift register = 1, not 0, so you'll execute the False case and not the code in your True case.
If you want to stop all event handling after the first event and your event handler is the only thing with its loop, from the event case (for the event you want to stop on), wire a True boolean constant out to
the Stop terminal of the loop containing your event structure.

First movie download report...

Yesterday I successfully downloaded my first movie from iTunes directly to my HD and this evening we watched it on my 40" Sony. I was very impressed with the quality of the video considering the source.
My hardware for this was a MacBook with 4MB. I purchased a mini DVI->DVI cord at my local Mac store for $20. I mated this cord to a DVI->HDMI cord which I inserted into my open HDMI port. For sound I bought a 6' 1/8" stereo jack->L/R RCA plug which went into the same port as the HDMI. To my eye, the video looked at least DVR quality and perhaps slightly better.
My TV has 3 HDMI ports and I'm now maxed out with my cable, Blu-Ray and MacBook inputs. Anyone considering buying a flat screen should strongly consider getting one with at least 3 HDMI ports.
Re the performance of my MacBook, I started with a nearly full battery. When the movie ended (around 2 hours), I only had about 15 minutes left on the battery gauge. Normally I get between 4-5 hours of play. The hard drive ran continually while the movie was running. I wasn't able to figure out how to turn the screen off on my MacBook. So, lighting that screen had to "eat" some battery. I read somewhere that the laptop screen could be closed when using an alternate video screen, but when I tried that, the computer went into sleep mode and stopped the movie.
For those of you that might be interested in trying this, Apple also sells a mini DVI-> VGA or to S-video or to A/V video. They all cost $20.
This whole thing was an experiment as I will be buying an Apple TV unit in a couple of weeks. Still, it's nice to know that movies can be played in this manner. Also, I was impressed with viewing pictures in this manner. Even my Excel spreadsheets were very easy to read. This mini DVI output will certainly get some use from me in the future.

Hi,
LOAD-OF-PROGRAM is the first event triggered but it is internal event.
This event keyword defines an event block whose event is triggered by the ABAP-runtime environment when an executable program, a module pool, a function group or a sub-routine pool is loaded in the internal session.
INTIALIZATION is the first report event get triggerd.
This event keyword defines an event block whose event is triggered by the ABAP runtime environment during the flow of an executable program, directly after LOAD-OF-PROGRAM and before the selection screen processing of any existing standard selection screen. This gives you the one-time opportunity to initialize the input fields of the selection screen, including those defined in the logical database linked with the program.

How do I register an event as a value in an array?

I have a boolean which is True whenever data I am recording exceeds a certain value. What I want to do is keep a log of every time this happens and store it into an array, preferably in a way that each event has a new number (e.g. first event is logged as 1, second as 2, etc.).
The aim is that every time this condition is met, an output signal is sent to another DAQ card, and the signal is dependent on the current event iteration (the computer reading from the other DAQ card can interpret this with if statements for the voltage ranges, which seems to work).
I would be very grateful if you had any input as to how to go about this.
Thank you very much!

How do I add one event to multiple, but not repeating, dates

I routinely need to add single events to 10 to 20 dates at once. These dates rarely line up in a repeating sequence. For instance I may need to schedule "appointment with John at 1pm" on M,Tu this week; W,Thu,Fri next week; M,Thu the following week. And "appointment with Jane at 10am" on M this week; Tu next week; Thu the following week.
I know I can copy and paste identical text in one at a time on each date but this is tedious.
Is there an app or trick I can use to do this efficiently? Previously I used an old version of Calendar Creator in which I could create an event and then push a toggle switch on all the days across a month in which the event would reoccur.
Thanks! I'm new to Mac and iCal.

Hello,
Welcome to Apple Discussions.
1. Make the first event in iCal when and how you want it.
2. If you are not in month view, switch to it.
3. Highlight the event in the calendar view and press Cmd-C (copy).
4. Click on the blank area on a day you want to copy to.
5. Press Cmd-V (paste).
6. Repeat steps 4-5 for all needed dates.
Best wishes

How can i use the same front panel graph in more than one events in an event structure?

i want to display the signals from my sensorDAQ in a graph.but i have more than one event in the event structure to acquire the signal and display it in the graph.the first event is to acquire the threshold signals and its displayed in the graph as a feedback.after the first event is executed, i will call the second event,where the further signals are acuired and compared with the threshold signals from the event 1.my question is how can i use the same front panel control in more than two events in the event structure?please answer me i'm stuck.

Hi,
I have attached here an example of doing the same using shift registers and local variables. Take a look. Shift register is always a better option than local variables.

How do I move a compound clip in one event to another event when it is used in a project?

I've been using FCPX since 10.0.3. The recent upgrade to 10.1 is forcing me to reorganize everything. At some point during the upgrade cycle, Apple decided to store ALL compound clips inside events, automatically, upon creation. I was oblivious to this decision at first. So here's what happened as a result.
I have 10 projects, numbered 1 through 10. My goal was to have one event for each project. However, it looks like most of my compound clips from my later projects got automatically created and placed in the first event (Video 1) instead of in the correctly numbered event. I'm pretty sure the clips INSIDE the compound clips are referencing the correct event; it's just the compound clip itself that resides in the wrong event. I'd like to move these compound clips over to the event they SHOULD have been created in, in the first place. However, I'm not sure if dragging and dropping them to the correct event will (a) create a new copy of the compound clip (one that is not referenced by any project whatsoever), or (b) move the original compound clip to the right event (removing it from the original/wrong event). Also, I'm really concerned about this, because I'm not sure how this affects the compound clip as used inside the actual project. I often have certain effects, color correction, etc. applied to the compound clip itself, and I don't want to lose that.
Any advice would be greatly appreciated. I really want to get these clips in order.

You can freely drag compound clips between events as you've seen.
If you do this between events in the same library, it will be a move by default; holding down the Option key will make it a copy operation.
If you drag between events in different libraries, this will be a copy operation. All clips contained in the compound clip will also be copied (or references as sym links) to the target library in order to keep the library completely self-contained (libraries never references each other and never span volumes).
