How to find syntax errors in TestStand?

Hi,
I have about 70 sequences and I'm trying to find any syntax errors, which evaded my "error radar". How can I find these in TestStand without moving through every step (which would around 1000 and more steps!)? I'm missing something like the "syntax" check in LabVIEW, which indicates right in your face, if you brake the block diagram.
Thanks for any help.

Checking expressions at edit time to make sure that they will evaluate correctly at run time is a tricky process. For instance, what if you are dynamically creating an array at run time, and then iterating through that array. Unless you give that array good default values (which may be difficult if it is an array of custom types), your expressions will not be correct at edit time, and could be flagged as errors.
However, this is a request that we have heard quite a bit, and NI is investigating ways to allow customers to validate their expressions before running a sequence.
In the meantime, one of the TestStand developers created a tool that does what Doug was describing: iterates through every property object in a file and if it is an expression, tries to evaluate it. This tool is written as a sequence file in TestStand 4.1. Please note that since it uses recursion to iterate through each property object, and since recursion with sequences can be rather slow, the performance of this tool may be improved by duplicating its functionality with a code module (rather than sequence steps).

How to check syntax errors in ABAP Queries

HI Guys,
How to check syntax errors in ABAP queries, Can please provide the T-Codes.
Advande thanks to everybody.
Thanks,
Gourisankar

Hi
with these you can check syntax errors and performance points
Hi
these all are doing t he same thing that is checking the program for better performance
Tools for Performance Analysis
Run time analysis transaction SE30
SQL Trace transaction ST05
Extended Program Check (SLIN)
Code Inspector ( SCI)
Run time analysis transaction SE30 :This transaction gives all the analysis of an ABAP program with respect to the database and the non-database processing.
SQL Trace transaction ST05: The trace list has many lines that are not related to the SELECT statement in the ABAP program. This is because the execution of any ABAP program requires additional administrative SQL calls. To restrict the list output, use the filter introducing the trace list.
The trace list contains different SQL statements simultaneously related to the one SELECT statement in the ABAP program. This is because the R/3 Database Interface - a sophisticated component of the R/3 Application Server - maps every Open SQL statement to one or a series of physical database calls and brings it to execution. This mapping, crucial to R/3s performance, depends on the particular call and database system. For example, the SELECT-ENDSELECT loop on a particular database table of the ABAP program would be mapped to a sequence PREPARE-OPEN-FETCH of physical calls in an Oracle environment.
The WHERE clause in the trace list's SQL statement is different from the WHERE clause in the ABAP statement. This is because in an R/3 system, a client is a self-contained unit with separate master records and its own set of table data (in commercial, organizational, and technical terms). With ABAP, every Open SQL statement automatically executes within the correct client environment. For this reason, a condition with the actual client code is added to every WHERE clause if a client field is a component of the searched table.
To see a statement's execution plan, just position the cursor on the PREPARE statement and choose Explain SQL. A detailed explanation of the execution plan depends on the database system in use.
Extended Program Check
This can be called in through transaction SE38 or through transaction SLIN. This indicates possible problems that may cause performance problems.
Code Inspector (SCI)
You can call the Code Inspector from the ABAP Editor (SE38), the Function Builder (SE37), the Class Builder (SE24), or as a separate transaction (SCI).
The Code Inspector indicates possible problems. However, note that, especially with performance issues: There is no rule without exception. If a program passes an inspection, it does not necessarily mean that this program will have no performance problems.

How to find flatfile errors while uploading data

hi all,
i hava a question... when i am uploading large amount of data (ex:1 lac records) in that 100 records are error records .. how to find the error records in flatfile before uploading.
regards shree.

Hi,
The only way to find out errors is to open the file from abap read through each record and validate it.
However , my approach would be to read through each record, validate it, if valid process it otherwise collect it in another auxilary internal table and then in the end log the errors for later processing.

How best to find syntax errors in a PDF

Hi,
I want to find out the best way for an end user to identify syntax errors in a PDF, such as "expected a dict object", which might occur when a user opens the PDF. I usually find these when using the Acrobat SDK to parse a PDF in some way. However, for an end-user, a tool would be necessary.
Using the Acrobat preflight tool enables you to browse the structure of a PDF and potentially see errors but that is not suitable for anyone other than an expert. What I am looking for is a way to check a load of files for these sorts of errors in a batch process so that a non-expert can identify the problem files that need fixing. Is there a good way of doing that?
Thanks
David

Thanks, that seems to do just what is needed.

MySQL syntax error with TestStand 4.0 database logging

I had been using MS Access database to log results which worked fine but the access database is too limited. Switched to MySql. Database works fine and I can query it from Visual C++ and was able to create all my result tables fine from TestStand.
I get a syntax error when actually trying to log results and it has to do with either a missing quote or and extra quote, I can't quite tell. I thought I saw a post on this somewhere but can't find it now. Here is the complaint from TestStand:
An error occurred calling 'LogOneResult' in 'ITSDBLog' of 'zNI TestStand Database Logging'
An error occurred executing a statement.
Statement: UUT_RESULT.
[MySQL][ODBC 3.51 Driver][mysqld-5.0.45-community-nt]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DEFAULT VALUES' at line 1

Number: -2147217887
NativeError: 0

Source: TSDBLog
And here is all that appears in the MySql logfile:
INSERT INTO UUT_RESULT DEFAULT VALUES
070914
You can't see it here but the string is truncated after the word VALUES. The next line starts with the odd number.
Any ideas?
Thanks,

Sure. There were two bugs in the ini file that contains the default TS schemas (I think it was Default_Database_Options.ini or like that...).
Anyway the table description for STEP_NUMERICLIMIT had for it's command line INSERT INTO MEAS_NUMERICLIMIT. I guess TestStand looked at that and said hmm I better create that table too. Then later down the page when you try to create MEAS_NUMERICLIMIT it says the table already exists even though it is empty. The generate SQL button builds a bad file and then the database viewer creates a bad database. I would have to go into MySql and drop the database. I had to save the schema under a custom name, edit it read it back in, generate a new SQL file, but then it would still fail validation because the ini files don't get updated until you exit TestStand. So basically I did this process 3 times before I got it right.
It's wasn't a big deal but it's amazing how a little thing can cause a lot of work.
The second bug, I'm not certain was initially in the file or somehow got set on the fly. There was a random int statement at the very end of the SQL table description for UUT_RESULT. It was also in the schema INI file. Since the int had no name and occurred in a odd place, it created a syntax error in MySql. Same fix as above.
But like I said it's working great now. I like this approach because I serve it to the net with Apache and parse the database with simple PHP scripts.

How to fix Syntax Error: Expected end of line, etc. but found end of script. in applescript?

I am making an applescript for my modding tool for Minecraft. It used to use multiple apps and I am now trying to make one app for all the tasks.
Here is the code:
say "You are running iCraft version one point one for minecraft version 1.2.5"
display dialog "Which tool do you want to use?" buttons {"Mod Installer", "Backup", "Restore"} default button 3
set the button_pressed to the button returned of the result
if the button_pressed is "Mod Installer" then
do shell script "~/desktop/iCraft/iCraft.app/contents/re…
display dialog "Insert all mod files into the Mods folder."
display dialog "Have you inserted all Mod files into the Mods folder?" buttons {"Yes", "No"} default button 2
if the button_pressed is "Yes" then
do shell script "~/desktop/iCraft/iCraft.app/contents/re…
display dialog "Finished"
else
display dialog "Insert mod files into the Mods folder and restart iCraft.app."
end if
if the button_pressed is "Backup" then
display dialog "Are you sure you want to backup your Minecraft.jar in it's current state?" buttons {"Yes", "No"} default button 2
if the button_pressed is "Yes" then
do shell script "~/desktop/iCraft/iCraft.app/contents/re…
display dialog "Finished, find it in your Backups directory in the iCraft folder"
else
display dialog "Backup aborted"
end if
if the button_pressed is "Restore" then
display dialog "Are you sure you want to restore your Minecraft.jar with your backup?" buttons {"Yes", "No"} default button 2
if the button_pressed is "Yes" then
do shell script "~/desktop/iCraft/iCraft.app/resources/s…
else
display dialog "Restore aborted"
end if
end
When I try to compile/run it gives me Syntax Error: Expected end of line, etc. but found end of script.

Your script got mangled when pasting it into your message, but the main problem looks like you are missing a bunch of end if statements. Unless your if statements are contained on one line, you need to terminate them with a matching end if statement - for example, the following are equivalent:
if someString is "whatever" then display dialog "foo"
if someString is "whatever" then
display dialog "foo"
end if

How to find out error segments in a group of Idocs

Hi,
1. For every 5 minutes Idocs are coming in to R3 from some third party systems, and this scenerio some of the Idocs are in failed status as well.
My doubt is how to see the all segments at a time, since there might be some problem with the data, so I need to check the each and every segment all time. Is there any way to findout all segments at a time for the group of the idocs of the same message type.
2. How to find out the error in segments of the idoc.
Many thanks in advance.
Thanks.
Ahmed.

Hi Mujeeb Ahmed
I dont have SAP System in front. Any way check the menu bar, there you can fine SEGMENT WITH ERROR OPTION

Help me find syntax error in AS3 code to chain FLV videos.

I posted a how to do this a couple of weeks back & someone was kind enough to offer this advice to an AS newbie...
"you should create a fla, drag an flvplayback component to the stage, create an array of your flvs, initialize an index at zero, assign the flv to start playing your first flv and increment the index in a function that executes when an flv complete and play that array element until all are played. you'll publish your html and swf from that fla."
And he gave me a code sample which is below... modified to show my "instance" name as FlvChain
and my flv file names... vid1.flv, vid2.flv, and vid3.flv...
My code...
import fl.video.VideoEvent;
var flvA:Array=["vid1.flv","vid2.flv","vid3.flv"];
var index:uint=0;
FlvChain.source=flvA[index];
FlvChain.addEventListener(VideoEvent.COMPLETE,completeF){
index++;
if(index<flvA.length){
FlvChain.source=flvA[index];
} else {
// all flvs played
When I attempt to Debug I get this message...
"1087: Syntax error: extra characters found after end of program."
I'm sure I made a silly error. I've never done AS before I'm running CS3 & AS3 on a PC with XP Pro.
Thanks for any help.

use:
import fl.video.VideoEvent;
var flvA:Array=["vid1.flv","vid2.flv","vid3.flv"];
var index:uint=0;
FlvChain.source=flvA[index];
FlvChain.addEventListener(VideoEvent.COMPLETE,completeF);
function completeF(e:VideoEvent)
index++;
if(index<flvA.length){
FlvChain.source=flvA[index];
} else {
// all flvs played

Trying to figure out how to find this error?

Hi,
I have a project that keeps throwing this error, but I can't see, to figure out how to find it:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
It's a very large project. How can I search for this?
thanks,
Dave

ok, so it showed me a few things... THANKS, but none of which were exactly a problem:
at ALeCard_CBP_0101_fla::MainTimeline/frame23()[ALeCard_CBP_0101_fla.MainTimeline::frame23:4 3]
at flash.display::MovieClip/gotoAndPlay()
at ALeCard_CBP_0101_fla::MainTimeline/fl_ClickToGoToScene2523()[ALeCard_CBP_0101_fla.MainTim eline::frame25:302]
so the top one is just a part of a button
downloadButton.buttonMode = true;
which is fine.
then, the other one points to a part of a function that I've used in a dozen other places and it works fine:
MovieClip(this.root).gotoAndPlay(23);
something I did find-and I still can't figure out why-is that download button was causing issues. I have NO idea why since it's an exact duplicate from another file.
but this is cool to have this information-thanks!

let us consider a scenario where i am trying to insert 40 colunm values into table and one column is causing the problem , how to find that column alone .

Oracle does not provide the column information in the error message and I don't know of any way to do so outside of developing something convoluted. For example:
SQL> DECLARE

3 BEGIN
4
5     te_row.empno := 1234;
6     te_row.ename := 'ABC';
7     te_row.job    := 'CLERK';
8     te_row.deptno := 1000;
9
10     INSERT INTO temp_emp
11          VALUES te_row;
12 END;
13 /
DECLARE
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: number precision too large

Hi Balaji,
After you copy a Std SAP Program into ZPROGRAM,
In ABAP Editor see Goto -> Attributes.
System will throw a pop-up window, In which press change original language.
then you can be able to change to English.

I check the documents ...it is written as a there is long back they modified the original T-code of 2001(report or userexit not sure) to allow only HR Department people , no one can enter the details apart from HR ,no-one else should be able to do that!!
Now i need to find where the error message is getting .............i dont know what is the best approach,
i debugged it(before savgin) but its too long to find......I put the break points for the user-exits available for the infotype(Total i found 16 Package PTIM) ......no user-exit is triggerring..i searching from morning....
The main problem is it is working fine for me.I am not getting error message...so unable to catch
Please help me how to search...or need to search with 'AUTH ' field? if so in how many programs?
or need to search using the 'MESSAGE' i just have the screen shot of the message..with the content how could i found that ??
waiting for your valuable inputs....
