How to determine data type of cell in Excel file

I have a company standard Excel file that needs to be read to determine what tests to run. I have no control over its format. I need to be able to tell what the data type is in order to read it using the LabView sample code. It is a hodge poge of numbers and strings. Some of the numeric fields are formated as hex while some are floating point. There does not appear to be a vi that I can call to determine info about the cell formating. As I remember it, the Windows Active X control for accessing Excel support that. I really was hoping to avoid dealing with the Active X control for Excel directly.
Any help/ideas?
Outputting it in CSV or similar is not an option.
Solved!

If you have to deal with Excel directly, I don't see how you're going to get around using Active X.

How to retrieve data from a read-only Excel file

Hi Developers,
I'm trying to retrieve data from a read-only Excel file. I used the same code that I used to retrieve data from a normal Excel file, but it can't work.
My code is as followed:
try
InputStream KpExcel = new FileInputStream("kp.xls");
HSSFWorkbook Kpwb = new HSSFWorkbook(KpExcel);
HSSFSheet Kpsheet = Kpwb.getSheetAt(0);
catch(Exception e)
e.printStackTrace();
System.out.println("Exception: "+e.getMessage());
The error I received is as followed:

How do determine data type?

I am trying to write my own binary file saver and I need to list the data type in the custom header. How do you do this in labview?

kameronrausch wrote:
The data acquistion spits out data in several different formats so a priori, I do not know the data type. It can be either a 32-unsigned int, 16-bit unsigned int, 8-bit unsigned int or the signed version of each one of these. To make the program general purpose however, I would like to incorporate floating point data points as well.
At some point you have to know what the data type is before start collecting data. If all you have is a stream of bits there is no way to determine what the data type is. What controls how the data acquistion is getting its data? If it is test specific you could use an external configuration file to store this and use that to determine how the data should be interpreted. If you have arrays of specificdata types you could use a polymorphic VI for your data writes. Based on teh wire type of the input the appropriate VI would be called. How is your data being passed from your data acquistion to the VI that will write it to a file?

But i am working in version 4.6c. do we have any method or anything that meets my requirement in 4.6c.
Please let me know.

How to read data in correct format from EXCEL file into an internal table??

Hi Experts,
My requirement is to upload data from an excel file on presentation server into an internal table on SRM server.
I used 'GUI_UPLOAD' function module to achieve the same but all the the data is getting uploaded in # only.I had set in the 'HAS_FIELD_SEPARATOR' to 'X' to overcome this problem.
But all the efforts are in vain. The function module 'ALSM_EXCEL_TO_INTERNAL_TABLE' doesn't exist on SRM Server and I am not getting any other function module having similar functionality available on SRM server.
I have written the following code:-
TYPES: BEGIN OF ty_addr_loc,
 userid TYPE xubname, "User Id
 addr_code TYPE char4, "3 Digit Site Location Code/4 Digit
 "Alternate Address
 loc_id TYPE bbp_location, "Indicator: Address is standard address

How to save data (DBL array) in a excel file

Ok, I am new into Labview. This question may seem easy for you guys, but for me, it is quite a challenge. I have current coming out of a loop. When the program stop, I would like to be able to save it as well as the time when it has been taking and the average current in a excel file. When my labview code stops, how do I do to get a pop up window which ask me where and what name to save it to? How do I get so that on the top of each column, it says : current (Amp) Time (ms) Average Current (amp)?
thank you very much,

Hello,
We love to see people catch the LabVIEW spirit and anything we can do to help
you through the initial learning process is our pleasure.
As KC suggested saving the file as a .csv is a good idea,
you can also save it as a txt file and open it with Excel specifying a delimiter
for the columns.
There is a really good example you can find in the LabVIEW
example finder if you search for the keyword ‘file’, the example is called “Write
to Text File.vi”. They use a Get date/time String to record the time when data
is acquired.
I have attached a simple Write to File picture of a VI that
takes a random number and writes it to a file. When I run the VI, a popup asks
me what I want to call the file. The first part writes the heathers on the
columns and inside of the for loop I save the data. Underneath the block diagram
is a picture of the output file when I specify the number of samples to be five.
If you want your file to be on a very specific format, you
can create a template file, read it in LabVIEW, and then add your data to it
and save it to a new file.
Hope this can get you started with your program.
There are a lot of good tutorials online on how to
get started using LabVIEW. Here is the link to a three hour
introduction course:
http://zone.ni.com/devzone/learningcenter.nsf/03f7c60f17aad210862567a90054a26c/60c2782788a811c986256cd50001a0a6?OpenDocument&node=200067_us
We are also comming out with LabVIEW 8 in November and we have a program called LabVIEW Standard Service Program
(SSP) that allows you to get automatic upgrades and updates. Please let
me know if you are interested in knowing more about it.

How to change data in decision table using excel file in operating system?

Hello, BRF Experts
I now brf + for the first time in the current project is being developed.
Now, project has been facing a big problem.
Develop system that was developed in the history of decision table in the operating system can be used to update excel file, etc. I do not know whether.
So, I was tested, but can not change data in decision table.
[ error message : system is not change allowed ].
The operating system itself to the current system setting is immutable and check it
: changes and transports for client-specific object -> no changed allowed
: cross-client object changes -> no changes to repository and cross-client customizing object.
Decision table in the operating system can update the details if I want to know what to do.
Maintenance view can be modified in the operating system as a decision table, I wonder if you can create a view.

Hi ,
Exchanging data with Microsoft Excel is done with the help of the XML-based file format (file extension .XSLX) introduced with Microsoft Excel 2007. If you are using an older version of Microsoft Office, you can download the Microsoft Office Compatibility Pack to upgrade the supported file formats from the Microsoft Download Center ([Exchanging Decision Table Data With Microsoft Excel |http://www.microsoft.com/downloads/details.aspx?familyid=941b3470-3ae9-4aee-8f43-c6bb74cd1466]). Once you have downloaded the Compatibility Pack, you have to install it on every workstation that has an older version of Microsoft Office installed.
Please refer the link-

Hope this helps.

Determine data type

Hi all,
I've got procedure for inserting data into value1 column of table1.
My need is to determine data type entered by user.
If data type is not number then user should receive error.
How do I perform it?

The easiest and most reliable way would be to declare the formal parameter as a number like:
SQL> create procedure p (p_num in number) as
2 begin
3     null;
4 end;
5 /
Procedure created.
SQL> exec p('a');
BEGIN p('a'); END;
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
ORA-06512: at line 1If you cannot do that, or want to be more "user friendly", then the only alternative is to test it and raise an error like:
SQL> create procedure p (p_str in varchar2) is
2     l_num number;
3 begin
4     l_num := to_number(p_str);
5 exception
6     when value_error then
7        raise_application_error(-20001, 'I know I said it was a string, but I really want a number');
8 end;
9 /
Procedure created.
SQL> exec p('a');
BEGIN p('a'); END;
ERROR at line 1:
ORA-20001: I know I said it was a string, but I really want a number
ORA-06512: at "OPS$ORACLE.P", line 7

How to determine IE type(32 bit or 64 bit) in a task sequence while updating Java

How to determine IE type(32 bit or 64 bit) in a task sequence
Hi,
Currently i have to update new version of Java after removing all the previous existing version of Java by using TS in SCCM 2007.
we have both 32 bit and 64 bit browser in the environment. I am stucked in determining whether the browser is of 32 bit or 64 bit.
How to determine IE type(32 bit or 64 bit) in a task sequence so that respective java can be installed for that IE browser.
will highly appreciate quick response.
Thanks in advance.
Daya

But you also need to install JRE x86 on x64 systems, since most people actually use the 32bit browsers on x64 systems.
The detection logic is actually pretty simple -- just check the right registry hive to find the installation location of the BIN\JAVA.DLL. Both pathnames are stored in HKLM\Software\JavaSoft\Java Runtime Environment\1.7 in the registry value "JavaHome",
but the x86 path is stored in the 32-bit hive and the x64 path is stored in the 64-bit hive.

Hi All,
can anyone tell me ...how to create data type from agiven xsd.
I need urgently....
thanks in advance....

import this XSD, load this in your mapping editor and then use this to crate the datatype manually.
Or, use XML spy, load this XSD and then you should be able to see the Structure, or,

How to check data type of the field symbol at run time

Hi,
My code is as following:
 LOOP AT <fs> ASSIGNING <wa_covp_ext>.
 ASSIGN COMPONENT 86 OF STRUCTURE <wa_covp_ext> TO <f_zzname>.
 IF sy-subrc = 0.
 ASSIGN COMPONENT 158 OF STRUCTURE <wa_covp_ext> TO <f_pernr>.
 IF sy-subrc = 0.
 SELECT SINGLE sname INTO <f_zzname> FROM pa0001
 WHERE pernr = <f_pernr>
 AND endda GE sy-datum
 AND begda LE sy-datum.
 ENDIF.
 ENDIF.
 ENDLOOP.
This query is giving dump when <f_zzname> is type P length 8 and decimals 2, because it tries to put PA0001-sname into it which is type C length 30. So I want to check the type of <f_zzname> before the select statement. If it is character 30, then I will write the select statement else not.
How to check data type of the field symbol at run time? If it's not possible, then can somebody suggest a workaround? Thanks.

check this ...
write describe statement ...
field-symbols : <f_zzname> .
data : sname like pa0001-sname,
 typ(10).
assign sname to <f_zzname>.
describe field <f_zzname> type typ.
write : typ. <-- typ contains character type in this case ..
U can check if typ is of character(C) if so .. write the select statement ...
