String to 2d array to excel sheet
Greetings,
I am a beginner at labview, tring to explore it. I am stuck in a task as follows
I have a txt file which i want to convert it into array then display it into excel file.
Below is the string data in the txt file
x=1.0,y=4.0,z=2.5,x=1.1,y=4.1,z=2.6,x=1.2,y=4.2,z=2.7,x=1.3,y=4.3,z=2.8,x=1.4,y=4.4,z=2.9,
I want to convert the above data to an array/excel sheet like below
x=1.0 y=4.0 z=2.5
x=1.1 y=4.1 z=2.6
x=1.2 y=4.2 z=2.7
x=1.3 y=4.3 z=2.8
x=1.4 y=4.4 z=2.9
Now i know that match mattern would be used to seperate the delimiter ',' but what after then, i m confused in how to progress further.
Please guide me how to solve this task
Regards

Hi,
Going by your original requirements, you want the spreadsheet to display "x=1.0", etc... in the cells. Just to confirm, you don't want values which could be plotted, you want a table with text that has the axis and an equals sign? If that is the case, then you just write the folded string into a text file with the .csv extension and Excel opens it no problems. See attached. If you what you really want is a table of numbers/values, then we have to modify the program a little...

Problem in reading data from Excel sheet to 2D string array (ActiveX & LabView).
I am trying to read data from Excel sheet to 2D string array (ActiveX & LabView). Error -2147352571 is generated (type mismatch) if cell value is "#NULL!", "#N/A" etc. What should I do?
Hello �
Is the error happening when the cell value is #NULL or #NA only?
Sometimes these errors occur because of an ActiveX object mismatch. The version of the ActiveX object might have changed or been updated since the VI was created. The VI tries to use an earlier, incompatible version of the ActiveX object.
To solve the problem, you need to link automation refnum terminal to the correct ActiveX object. To do so, right-click an automation refnum terminal and choose Select ActiveX Class»Browse from the shortcut menu. From the Type Library pull-down menu, select the latest version of the library you want to use, such as Microsoft Excel Object Library. In the Objects list, select an ActiveX object, and click the OK button. Link ea
ch automation refnum terminal in the VI and its subVIs until the run arrow is not broken. Also, you might have to replace some or all of the Invoke Nodes and Property Nodes for the ActiveX objects.
Also, I came across this Knowledgebase. The error number is slightly different but it is always good to check it out and make sure it is not your case.
Hope this helps.

How to insert 2-D array of elements in excel sheet
I have a 2-D array of elements. I want to insert this array into an excel sheet and display the data in a graph. I used the example "excel insert table" but the problem with that VI is, it is inserting the elements cell by cell which is taking long time. I am wondering whether there is way to insert a complete column or row into excel sheet at a time.
Thank you,
Mudda.Hi,
Try this vi which inserts the table in one operation. You can modify it to suit your purposes.
Hope this helps.
Edit: Should note that it works for both string and numeric array inputs.Message Edited by DavidT on 06-29-2005 10:09 AM

Identifying text file names and importing on single Excel sheet
Hey!
Does anybody can help me with Excel VBA macro code in order to import data from text files into single Excel spread sheet? I want to create User Form where user can select start and end date of interest and macro code will import
bunch of text files depending on user demands...
My text files are named: 20130619004948DataLog.txt (meaning: yyyy mm dd hh mm ss). Text file contains recordings for each 15 seconds... It would be great to omit time tail (meaning that user can only specify date). Text files for one day of interest (I have
text files covering whole year):

i have tried some of the example given in the discussion forum but its not giving the right range
Rgrds
HKTthks to all for the valueable comments
let me explain my application more, to clear the concept of using excel in this particular application
I am storing the data(time/temp) in the binary format on the hard disk.
the excel part comes when user want to have the excel report for its analysis .
that is user can use the data but soring it in the excel (format i have shown) as well as chart ( for better visualization)
the first part(insert data into excel sheet) i have made using activex control but in the scond part( insert chart into excelsheet) when i give the range specifed in the excelsheet it give me the error 3008
it is better to make chart by using 2D array of string but i am unable to find the result for the same

Unknown column in the excel sheet created using Export to Excel
Hi,
I created an excelsheet for the table data using the below link
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/user-interface-technology/wd%20java/wdjava%20archive/exporting%20context%20data%20into%20excel%20using%20the%20web%20dynpro%
20Binary%20Cache.pdf
but problem here is when i open the excel sheet it is having some unknown columns apart from the expected like amount/#agg next to the actual column amount and it is happening only for the cloumns which have some numbers.
I dont know where these columns are coming from.
Send me the solution and points will be rewarded for the helpful answers.
I want to put some name to the excel file instead of using system created file name.for this requirement where do i need to change the codeHi,
You can export to excel even not relating with any libraries
Follow this way..
Take one singleDimensional array, arrColNames[], and one Two dimensional array, arrValues[][].
File f=new File("Sample.xls);
FileOutputStream fos=new FileOutputStream(f);
for(int i=0;i<arrColNames.length;i++)
fos.write(arrLabels<i>.getBytes());
fos.write("\t".getBytes());
fos.write("\n".getBytes());
for(int j=0;j<noOfRows;j++)
String arr[]=arrValues[j];
for(int a=0;a<arr.length;a++)
if(arr[a]!=null)
fos.write(arr[a].getBytes());
fos.write("\t".getBytes());
fos.write("\n".getBytes());
fos.flush();
fos.close();
The exported excelFile will be stored in your server. If you want to open it using FileDownLoad UI Element,
Create value attributes resource of type Resource, behaviour of type FileDownLoadBehaviour, reso of type String, fileName of type String , Then then append this code
FileInputStream fis=new FileInputStream(f);
FileChannel fc=fis.getChannel();
byte data[]=new byte[(int)fc.size()];
ByteBuffer bb=ByteBuffer.wrap(data);
fc.read(bb);
fis.close();
IWDCachedWebResource objCachedWebresource=null;
if(data!=null)
objCachedWebresource=WDWebResource.getWebResource
(data,WDWebResourceType.XLS);
objCachedWebresource.setResourceName(f.getName());
wdContext.currentContextElement().setFileName(f.getName());
wdContext.currentContextElement().setResource(objCachedWebresource);
wdContext.currentContextElement().setReso(objCachedWebresource.getAbsoluteURL());
wdContext.currentContextElement().setBehaviour(WDFileDownloadBehaviour.ALLOW_SAVE);

Simulate "excel sheet" in a BLOCK FORM
Do you Know if it is possible to simulate an "EXCEL SHeet" in a block form ???
Thank You !I have to ask, since I am looking at grid beans. Does anyone know of a bean implementing a grid that would work with Forms 9i? I had successfully implemented this type of functionality with ocx's in prior version.
I see how to call methods and set properties of beans in the UI, but what do you do when the methods use objects like a table row (an array of strings) or more complex objects as parameters?
I located a couple of beans like this implemented in swing, and get them into a bean area on a form canvas. However, in both cases, the bean area cannot be dragged around or resized in forms developer, say, like the progressbar example or indeed other beans I have used. Is there a document describing how a bean has to be designed to be fully operable within the developer environment ?
Help on any of these questions appreciated. -

On excel sheet upload read the workbook and populate data to sharepoint list
Requirement in my current project:
In a document library when I upload an excel sheet, a specific workbook has to be read and the contents have to be uploaded to a sharepoint custom list.
The approach followed was create an event receiver and register as a feature. Following is the code for event receiver.
public override void ItemAdded(SPItemEventProperties properties)
base.ItemAdded(properties);
var list = getSPList("{150301BF-D0BD-452C-90D7-2D6CD082A247}");
SPListItem doc = properties.ListItem;
doc["Msg"] = "items deleted from req list";
doc.Update();
string excelname=doc.File.Name;
System.Diagnostics.EventLog.WriteEntry("ExcelUpload", "calling read excel");
string filepath = doc.File.Url.ToString();
doc["Msg"] = "excel name" + excelname + filepath;
doc.Update();
readExcel(excelname,filepath);

//my code breaks or fails when cursor reaches this statement. I am not able to open the excel sheet, there is no //problem related to the permission. same code snippet works in a console application. but when tried as an

Is this the only approach to meet this requirement or is there any other way to crack it. sharepoint techies please help me.as you described the scenario of the event that it should happen when user upload excel to a document library. Event Receiver is your best bet. However if you would have a requirement that users can send excel files any time to a network file location and
you want to pick it, read it and create list items etc. You would write a sharepoint timer job that would run every 10 minute to check for file and if available on the network drive, perform the operation etc. so that users who send excel file does not need
to come to the sharepoint etc. You can see that you have Event Receivcer option or Timer job option OR you would write a console application to trigger the code at a scheduled time on sharepoint server etc. so you are using the event receiver in the correct
scenario.

Unable to display double values in Excel sheet using JExcel API
Hi
I am writing code to generate report in the form of Excel Sheet using JExcel API.
Everything is going fine but whenever I want to put some double values in a cell it is only showing 2 decimal places. My problem is "I want to show upto five decimal places".
Any kind of reply might help me lot.
Thank U.If you enable the submit zero option, it still happens? This is a new feature on the display tabl
#NumericZero Enhancements
To display a numeric zero in place of an error message, you can enter #NumericZero in any of the three Replacement text fields. When you use the #NumericZero option:
· Excel formatting for the cell is retained.
· All calculations with dependency on the cell will compute correctly and will take the value of this cell as zero.
· This numeric zero is for display only. When you submit, the zero value is NOT submitted back to the data source.
You cannot set display strings for cells that contain an invalid member or dimension name (metadata error). Metadata errors produce standard descriptive error messages.
Errors are prioritized in the following order from highest to lowest. The error message for a higher-priority error takes precedence over that for a lower-priority error.
1. (Highest) Metadata errors
2. #No access
3. #Invalid/Meaningless
4. #No data\Missing -
How to read the data in excel sheet
Dear sir,
How to read the data in excel sheet when i recieve a data serial communication... ie i have store a data in excel such that
Cell A Cell B
A Apple
B Ball
C Cat
D Doll
when i recieve A from serial communication i have to display Apple, and when i recieve B i have to display Ball and so on..Hi,
I would recommend you to have a look at the VI attached. It makes use of a VI named 'Read from Spreadsheet' to read the row and column data from the tab delimited excel file. The read data is then searched for the Alphabet specified and finally returns you the corresponding string. The test file used to validate the operation of the VI is also attached.
Trust this would help you solve the issue.

Report using excel sheet as data source not working when deployed to production.
I have a set of SSRS reports that use an excel sheet as a datasource.
Now when I preview the reports or run them in the Visual Studio IDE on my local machine i.e
the development machine, the reports run fine & display all correct results.
However, when we deploy the reports to the Production machine which is on a separate server,
the following error message is displayed :
"The current action cannot be completed. The user data source credentials do not meet the requirements to run this report. Either the user data source credentials are not stored in the report server database, or the user data source is configured not to
require credentials but the unattended execution account is not specified. (rsInvalidDataSourceCredentialSetting)"
I've copy pasted the connection string used for connecting to the excel file as reference :
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\MyFolder\CurrentFile.xlsx;Extended Properties="Excel 12.0;HDR=Yes;";
The excel file has also been uploaded to the machine housing the reporting server (i.e to C:\MyFolder location)Hi Aaakar,
From the error message, please try to change the setting of Credential type for the data source on report manager as follows:
Go to the Data Sources properties page.
For the Connect Using option, select Credentials stored securely in the report server.
In User Name and Password, type credentials that can be used to access the database. If you are using SQL Server as the data source, the user name must be valid for both logging on to the server and for accessing the database that contains the data for
the report.
If the user name and password are credentials for a Windows account, select Use as Windows Credentials.
If you want the report server to pass the credentials of the user accessing the report to the server hosting the external data source, click Windows Integrated Security. In this case, the user is not prompted to type a user name or password.
For more details about Configure Data Source Properties, please see:
http://technet.microsoft.com/en-us/library/ms155882.aspx
Hope this helps.
Thanks,

How do I search for a value in an Excel sheet using ActixeX
I am already accessing my excel sheets however I need to be able to search the sheet for a certain value and return the row/cell location. Is there an activeX control that can do this?
You will need a reference to the range to search. This can be the entire sheet if you wish. Just wire that to the method node Find. Here you can specify all of the typical search options. Wire your string or number into the What input. For the what to LOOKAT value, use -4163 for Value and -4123 for formulas.
The reference returned is the range of the found value. You can wire it into the property node Row and Column to get the location.
