How to lookup a value in a 2D array from an Excel file - Dasylab version 12 Pro

Hi, I am new to this forum and am looking for some advice on a worksheet I'm trying to construct. I have an Excel spreadsheet that is basically a 2D array, and I want to use Dasylab v12 Pro to be able to import a value from this array based on user selections from within the Dasylab worksheet.
Column A lists 200+ diesel engine models. I've shown 9 in my Excel attachment...one model per row (shaded in yellow), and each engine model can be run at several speeds (shaded green in columns B thru F). For an engine in a given row, combined with a chosen operating speed gives you a corresponding horsepower (blue shading).
I have this Excel sheet saved somewhere on my C:/ drive, and what I want to do is when the user starts the Dasylab worksheet he will select from a drop drown menu to choose the engine model (ie A, B, C, etc) and another drop down menu to choose the speed (ie 1470, 1760, etc). I know that I can make a drop down menu with a Coded Switch within Dasylab, however it seems only 16 choices can be made from each switch, so for my 200 engine models I will need 13 switches! I know I can assign a text description like "Engine A" to a numerical value within that coded switch. Somehow I need to take those two selections made within the Dasylab experiment, and read this Excel file (ie my database of all of these 200 diesel engine models) as a 2 dimensional array by row and column to spit out the data value (the blue numbers) back into Dasylab.
The goal is to take the engine model, speed, and the horsepower obtained from the array search and write these to an .asc file that I will create a running log of this data. So, after the test page is run 50 times it will have 50 rows of data containing these 3 parameters. There is some other test data taken from my data acquisition that goes along with this, however that's not part of my 2D array predicament.
I'm taking a guess that I need to do something with global strings & variables, and some how import them and export them with an ODBC in/out module. This is something I've just never worked with before so I am a bit lost. Obviously I can just make the user type in the engine model and speed as a startup parameter at the start of the test and save that to a variable or string, but I want to make it idiot proof so that the two selections (ie row and column) can be chosen from a pre-set list and will yield my data value. Everything else related to Dasylab I am pretty proficient with.
Thanks,
Mike

This would be the best way.
Also, with version 13 they started using Phyton to create custom modules that can be programmed in DASYLab.
We arte learning this right now and I know that you can use standard message dialogs with that as well.
I would suggest to you to download a demo of V13 and take a look at the Pyton module.
Also, usually DASYLab system intgretors like us, can provide services also on things like this including Excel programming for pre and post analisys

How can I import contacts into my icloud contacts from an excel file?

I need to add contacts to my icloud contact data base. Can I import from an Excel file?
Thanks,

Not directly, export from Excel to a .csv file, then convert the .csv file to a .vcf (vCard) file. Then iCloud can import the vCard file.
Here is a free csv to vcard conversion utility.

How to add bookmarks automatically in a monthly report from several excel files?

Hello!
I´m using Excel 2010 and Adobe Acrobat X Pro.
I´m used to create a monthly Report in which several Excel files are combined. I usually sort the booksmarks´ hierarchy manually.
I´m searching for a method to standardize this work.
I it possible to use Acrobat Pro XI and it´s Action Wizard, is that possible?
Best regards, Chris.

Is the length of the reports always the same? If so then a bookmarks
structure can be quite easily added using a script.
If not then it still might be possible but will require a much more complex
script to identify and then bookmark each report (or part thereof)
separately.

How can I use Automator to extract specific Data from a text file?

I have several hundred text files that contain a bunch of information. I only need six values from each file and ideally I need them as columns in an excel file.
How can I use Automator to extract specific Data from the text files and either create a new text file or excel file with the info? I have looked all over but can't find a solution. If anyone could please help I would be eternally grateful!!! If there is another, better solution than automator, please let me know!
Example of File Contents:
Link Time =
DD/MMM/YYYY
Random
Text
161 179
bytes of CODE    memory (+                68 range fill )
16 789
bytes of DATA    memory (+    59 absolute )
1 875
bytes of XDATA   memory (+ 1 855 absolute )
90 783
bytes of FARCODE memory
What I would like to have as a final file:
EXCEL COLUMN1
Column 2
Column3
Column4
Column5
Column6
MM/DD/YYYY
filename1
161179
16789
1875
90783
MM/DD/YYYY
filename2
xxxxxx
xxxxx
xxxx
xxxxx
MM/DD/YYYY
filename3
xxxxxx
xxxxx
xxxx
xxxxx
Is this possible? I can't imagine having to go through each and every file one by one. Please help!!!

Hello
You may try the following AppleScript script. It will ask you to choose a root folder where to start searching for *.map files and then create a CSV file named "out.csv" on desktop which you may import to Excel.
set f to (choose folder with prompt "Choose the root folder to start searching")'s POSIX path
if f ends with "/" then set f to f's text 1 thru -2
do shell script "/usr/bin/perl -CSDA -w <<'EOF' - " & f's quoted form & " > ~/Desktop/out.csv
use strict;
use open IN => ':crlf';
chdir $ARGV[0] or die qq($!);
local $/ = qq(\\0);
my @ff = map {chomp; $_} qx(find . -type f -iname '*.map' -print0);
local $/ = qq(\\n);
#     CSV spec
#     - record separator is CRLF
#     - field separator is comma
#     - every field is quoted
#     - text encoding is UTF-8
local $\\ = qq(\\015\\012);    # CRLF
local $, = qq(,);            # COMMA
# print column header row
my @dd = ('column 1', 'column 2', 'column 3', 'column 4', 'column 5', 'column 6');
print map { s/\"/\"\"/og; qq(\").$_.qq(\"); } @dd;
# print data row per each file
while (@ff) {
    my $f = shift @ff;    # file path
    if ( ! open(IN, '<', $f) ) {
        warn qq(Failed to open $f: $!);
        next;
    $f =~ s%^.*/%%og;    # file name
    @dd = ('', $f, '', '', '', '');
    while (<IN>) {
        chomp;
        $dd[0] = \"$2/$1/$3\" if m%Link Time\\s+=\\s+([0-9]{2})/([0-9]{2})/([0-9]{4})%o;
        ($dd[2] = $1) =~ s/ //g if m/([0-9 ]+)\\s+bytes of CODE\\s/o;
        ($dd[3] = $1) =~ s/ //g if m/([0-9 ]+)\\s+bytes of DATA\\s/o;

How to find the arguments of a static method from the class file

Hi,all !
How to find the arguments of a static method from the
class file? for example, when we meet a bytecode
"invokestatic", how can I know the arguments of this
static method?You mean
1. The values?
2. Argument names?
3. Argument signatures.
I would suppose for the last that the easiest way would be to parse the signature string.
The first is not possible - not from the class file.
The second is only in the debug information stored in the optional part of the class file. And figuring out the format for that is going to be a problem.

How to display WBS element while parking FI document from an excel??

I'm using BAPI_ACC_DOCUMENT_POST to park/post FI document from an excel file. Accounting Document Numbers are generated that triggered the posting. When i'm viewing the generated document in transaction FBV0/FB03 it's found that the WBS element is appearing blank when the document is parked. But it's appearing fine when the document is posted. I'm unable to find the difference.

Can you let us know how were you able to PARK documents using BAPI_ACC_DOCUMENT_POST? Is there an exit provision in this BAPI? Thanks in advance.
