Purpose of Check statement..?

Hi All,
What will happens when I write check statement in the loop
Loop at temp_glpct.
Check temp_glpct-RYEAR IN RYEAR.
Akshitha.

If you use the CHECK <expr> statement within an event block but not within a loop, and the condition <expr> is not fulfilled, the system exits the processing block immediately.
<expr> can be any logical expression or the name of a selection table. If you specify a selection table and the contents of the corresponding table work are do not fulfill the condition in the selection table, it is the same as a false logical expression.
If the CHECK statement occurs in a loop using DO, WHILE, or LOOP, it is the loop that terminates, not the processing block.

Use previous "Delete from hard disk" checked state?

Is there any way for the program to use the previous "Also delete selected item(s) from the hard disk" checked state in the file deletion confirmation dialog? It gets tedious to check it every time I want to delete a file and if I forget to do it I will have an extra file sitting on my hard disk not in my catalog.

A quick shortcut that I use is to hit the spacebar (checks/unchecks the "delete from
hard disk" option), then hit the enter key to complete the process.

BT Infinity checker states Brentwood as enabled - ...

I'm sure I'm not the only frustrated one in this position.
The online checker states that Brentwood exchange is enabled for infinity (apperantly one of the first in the country).
However, a check against my phone number states that I cant get Infinity. The max I get is ADSL at 1mbit.
I know that all cabinets are not active but I can't get any information as to which cabinet I connect to and when that will be enabled for Infinity.
I can't get any help from the BT customer service dept.
Any help would be appreciated.

HI
CHECK log_exp.
If the statement CHECK is executed outside a loop and log_exp is incorrect, the statement terminates the current process block. You can specify any logical expression for log_exp.
The behavior of the runtime environment after exiting the processing block is described under Exiting Processing Blocks.
SAP recommends to use this procedure with the statement CHECK only inside loops (see CHECK (Loops) ).

Is it possible to get menu item checked state?

In a script I need to know the state of a menu items checked state - e.g. the View/Proof Colors menu item.
Is that possible? (and of cause if it is how do I do it?)
Thanks,
Jack

The reason I need the state of "Proof Colors" is that I want to turn on/off the visibility of a layer set depending on its state.
In the layer set I would have my printing adjustments layers. This way it is very easy to compare the image with the softproof. When "Proof Colors" is turned off the printing adjustment layer set would also be turned off - displaying the image without any printing corrections.
When "Proof Colors" is turned on the printing adjustment layer set would also be turned on - displaying the softproof with printing corrections applied.

Reading checked state of checkbox

Hi there:-
'Sorry to post such a simple question but I can find the
answer in the Dreamweaver online reference, and I have wasted a lot
of time trying to find the answer.
I want to read the checked state of a given checkbox and then
if value of true is returned invoke function "A" or if false is
returned invoke function "B".
Based on what I found in the reference I set up a variable to
capture the state of the checkbox as follows:
function checkboxState()
var checkState = document.all.nameOfCheckbox.checked;
if (checkState == true)
statements
else
if (checkState == false)
statements
The check box is setup as follows:
<input name="nameOfCheckbox" type="checkbox"
onClick="checkboxState()">
This doesn't work and I don't know why. I wondered if I had
to define the checkbox in a particular way, e.g. using the value
attribute or something, but the reference did not indicate this.
If anyone can help I would appreciate it.
Thanks!

Hi Jules,
Thanks for the tip. It worked. I have seen people set up an
if statement without any argument "if(checkStatus)" but I don't
entirely understand the mechanics of what this is doing. (That is,
how a true or false is passed to the variable) But I originally
learned to code COBOL so maybe I am too old fashioned.
Thanks,
Linda

AS3 swf TOC check state

Hi, I currently have a swf animation on a slide and thru as3 I use the rdcmndNextSlide so it moves to the next slide but on the TOC the state doesnt become checked. any way to fix this?

Captivate only marks an item as completed on the TOC if that slide has been played all the way to the last frame before moving to the next slide.
You can force the TOC to show any slide as ticked using the TickTOC widget.
More information about the widget here.
Trial widget versions available for download here.

EJB and ADF- Checking State of Entity Bean before Commit

Hi All,
I have created a sample using Ejb as business service and then created 2 forms in page and i am calling only one merge action for 2 forms.
I need to validate whether the data is modified or not....in business service layer...
So my doubt is how to check the State whether it is modified or not... or how can i use EntityFacadeImpl class..Any link or suggestions??
I am using Jdev 11.1.1.5
Regards
Karthick

Hi,
+.. or how can i use EntityFacadeImpl class+
expose a method onthe facade (e.g. checkDirtyState) that accesses this class for the transaction state and that returns true or false. This then is exposed by the DataControl and you create a method binding in teh pages PageDef for it. You can then access it as
BindingContainer bindings = ... get access to the binding layer ...
OperationBinding checkDirtyDataState = (OperationBinding) bindings.get("Name of Method Binding");
Object outcome = checkDirtyDataState.execute();
if(outcome != null){
   if ((Boolean)outcome == Boolean.TRUE){
      //do this
else{
    //do that
}A Second option is to add a transient field to the entities that indicates client side changes. You then iterate over the DCIteratorBinding reference checking if any entity in it has been changed (identified by the dirty flag)

Check statement.

Hi,
I am using the following stat for checking whether the the TCODE is in the given range in tab lt_tab3.
If i give values in in LOW & HIGH and In HIGH the following stat working fine. But If i give the value in Only Low field Bothe stat r not working.
CHECK lt_tab3-tcode between lt_tab1-low and lt_tab1-high.
OR (I'm using only one stat from these)
IF LT_TAB3-TCODE GE LT_TAB1-LOW LT_TAB3-TCODE LE
LT_TAB1-HIGH.
Give me suggestions

Hi,
I think you can do some changes to the internal table first.
if the lt_tab1-high is initial.
lt_tab1-high = lt_tab3-tcode.
endif.
Then you can use one of the following statement:
CHECK lt_tab3-tcode between lt_tab1-low and lt_tab1-high.
OR (I'm using only one stat from these)
IF LT_TAB3-TCODE GE LT_TAB1-LOW LT_TAB3-TCODE LE
LT_TAB1-HIGH.
Hope this will help you.

Is there an inexpensive APEX report printer for invoices/checks/statements?

I am considering using APEX for a billing/payments type system for a small company. BI Publisher is not an option for them due to cost. Has anyone used a free or low-cost product to successfully print detailed reports such as invoices, statements, checks, etc. from APEX?

Andreé,
o no problem
1)
first make an invoice layout with field holders placed in between ##
e.g. Dear Mr #CNAME# find here your latest invoce and so no
just make it in wordpad, word or openoffice
and save it in an RTF file
I then copied the RTF in a CBLOB field using TOAD
2)
load this clob in clob variable in a pl/sql procedure
mix your RTF with real data, f.i. #CNAME# will be replaced
using pl/sql : replace('#CNAME# , rec.name); and so on for all fields
the end result is the invoice as rtf
the idea comes from this application from oracle called mailmerge

How the check statement works in a a loop

Hi gurus,
assume itab has 5 records.
Loop at itab.
ctr = ctr + 1
write: sy-tabix.
check ctr = 3.
delete itab
endloop.
options:
      1 2 3 4
      1 2 4 5
      1 2 3 4 5
      1 2 3 3 4
the answer is 1 2 3 3 4.
Pls give me the expalanation.

Hi,
Here is the explanation for ur logic.
Initially ctr = 0.
1st record of itab:   ctr becomes 1. and sy-tabix = 1.
                              Check condition fails as ctr <> 3. so control goes back to starting of the loop.
2nd record of itab : ctr = 2, sy-tabix = 2. once again condtion fails ctr <> 3. control goes back to the starting of the loop.
3rd record of itab (3rd loop) : ctr = 3, sy-tabix = 3. Check condition satisfies ctr = 3. So itab record (3rd record) gets deleted. i.e., now 4th record will become as 3rd record.
4th loop : As 4th record replaced as 3rd record. the values will be as follows
                  ctr = 4, sy-tabix = 3. Check condition fails as ctr = 4, but not 3.
Hence the result till 4th loop is : 1 2 3 3
For the next loop, result will be 1 2 3 3 4
Hope it is clear.

Purpose of Check Boxes on New ITunes

I just downloaded the newest iTunes. A check box appears on every song and is checked. When I uncheck it my song disappears. Anyone know what's going on???

Are you looking in a smart playlist where the rules are "Match only Checked Songs" and "Live Updating"?
If you want to check everything, go to the main music listing, press sommandkey while checking a song.
