Excel data write using report generation vi's

I can read data from an excel sheet but can not figure a way to write data to specific cells using the LabView report generation vi's.

In the "Excel Easy Table" VI you can specify where you want a table to be placed by wiring a value to the 'Start (0,0)' input. If you want more control than that you will have to open the "Excel_Insert_Table" vi and modify it. It is located in the _exclsub.llb library. I highly recommend making a backup copy of this llb before modifying any VI's in it.

Hi Palavi,
you try to select a specific worksheet what is not existing, therefore just select "Channel Power" (and not Power Channel) and it should work for you.

Problem with writing continuous data to excel using using Report Generation vi's

Hey Everyone,
I am trying to read the data from DAQ and write to excel continuously using Report Generation vi's.
But when I run the VI, it writes only one interation of the while loop (gathering data from DAQ continuously) and doesn't append the data into the same file when I run it again after stoping the VI.
I have attached the VI i created. Please let me know if you have any idea to solve this issue.
Thanks

There are two problems with your VI. First, the basic logic of writing/appending to a file (Excel, TDMS, anything) should go something like this: Open the file, position yourself at the end of the file, then, in the loop, acquire data and write it to the file until you are finished with data acquisition. When you exit the acquire/write to file loop, then close the file. In particular, the opening and the closing of the file should not be inside the loop.
As others have pointed out, writing to Excel might not be optimal, particularly if you are acquiring data at a high rate (and would therefore be writing a lot of data). We actually use Excel in our data acquisition routine, mainly reading from a WorkSheet to get the parameters of a particular stimulus, but also writing the outcome of the response to the stimulus. As it happens, our "acquisition rate" in this example is on the order of several samples per minute, so there's no problem using Excel (we also sample 16 channels of analog data at 1 KHz -- this gets written as a binary file).
Second, if you really do want to use Excel, use the (existing) Excel file to which you want to append as the "template" argument of the New Report function. Then use the Excel Get Last Row function to position yourself at "end of file", as noted above.
Good Luck.

I am using report generation toolkit 1.1 with Labview 7.0 and Office 2003 professional. The create new report VI opens Excel but throws error (-2147167262- from automation open VI) when I try to open MS word. please help...

Hi Leo22,
Does this error occur if you use any of the example programs that come shipped with LabVIEW? I would try opening one of the examples that write data to Word and see if those give you an error. Also, have you tried just putting down a New Report.VI and change the report type to Word? If this simple vi (that's all you need to open Word) breaks, I would check to see if there are any instances of Word still open. Check the task manager to see if any word processes are still open. There should not be a problem accessing Word 2003 from LabVIEW 7.0. If neither of these solutions work, please give some more detail about your application and we can research further. Thanks!

How to populate the last empty row in Excel without using Report Generation Kit

I wrote a Labview SUb Vi that uses Report Generation Toolkit that is not loaded on the test stand. I am looking to convert it from Report Generation Vi like New Report, Append Table to Report, Dispose Report. The tunneling through all the report generation Vis seems extensive. Code is attached. Thanks, Greg
Greg

Thank you that was a big help...
I used the Excel Forum to get a lot of great ideas. My code is almost working.
There is a 2-D String Array that represents the String data that I am exporting to the Excel File Sheet 1 - 5.
I am attempting to determine the last populated row in sheet 1 then populate the next row of Sheet 1. Since all 5 sheets are populated every time, I should not have to search every sheet for the last row.
I am getting two row populated on sheet 1 with seeming the same data.
I found an AXExcelWrite2D ArrayWorksheet.vi that I thought would work. I think there is a Table determination that is causing me problems. The link is http://lavag.org/topic/13324-labview-and-excel-activex-or-ado/. The Application Invoke Node has a convert formula with "FromReferenceStyle" with R1C1 Attached to it. I am not sure what this function is doing. When I try to bring the function help up, there is a missing file.
I am including both the new active x vi and the report generation vi. Report Generation VI works.
I would appreciate any assistance I can get on this.
Thanks
Greg

Exporting to Excel data only using sub reports in Crytal 9

Post Author: pmstar
CA Forum: Exporting
I am using Crystal 9 verision.
I have .rpt file that used 4 sub reports .In the main report I placed all the sub reports in the(detail section) row and using the data for some caluculation in the main report to generate report fields.I placed the main report fields in next row( in detail section).However when i export the report .Its generating 5 empty rows and 3 rows with 0. I have pretty much followed the solution from the article "c2017620" published in BO.
Since i used the sub reports only to get some value for main report calculations .Is there any workaround for the following issue
1.I do not want to print the subreport data when exported to excel data only.
2.how can i get rid of the blank rows
We have a lot of reports which has the same issue and we need to get the reports to work in Excel Data only .The reports works perfect when used in PDF format but its mandatory that we need to give the reports to the client using Data only.
If possible, when responding with your recommendations, please include detailed steps. It would be very helpful.Thanks in advance,

Hi,
Of what i gather from ur scenario...this is what i did in one of my reports.
I had to use two subreports and they had to occupy one cell each, in line with other fields.
To obtain that,all the fields required in the subreport i put them into a text box.Therein restricting the fields to the txt box only...
Then import that sub-report as it is.
It worked for me....
try out...
All this only if've understood u right...

Unmerge cells using report generation

Hi,
I have an issue using report generation toolkit, I'm writting text data to a range of cells and the cells get merged because of that. So I need to unmerge cells in order to be able to write again in thoose cells, because if the cells are merged writing cause an error.
I have found a VI in the report generation toolkit to merge cells but I can't find one to unmerge them.
Is there a way to do that?
Thanks
Olivier

Hello Olivier,
What version of LabVIEW do you have?
How are the cells getting merged?
Can you provide information about the error message you are receiving?

Error when using Report Generation Toolkit

Hi, all,
I am using Report generation toolkit to generate a report in either
word or excel format. But i even can't run the "new report.vi". It
returns an error code of "Bad variable type (-2147352568)", and seems
this error comes out from the "call by reference" after the
word/excel's "open VI reference". I have checked the folder
"C:\Program Files\National Instruments\LabVIEW
6.1\vi.lib\addons\_office", there are "_exclsub.llb" and
"_wordsub.llb". The respect VIs are all inside. I don't know why there
is such error. Currently i am using labview 6.1, Microsoft office 2000
and Windows NT 4.0.
Your kindly help will be appreciated very much!!!
Thannk you in advance!! ^_^
Your sincerely,
celery

So, if you place just New Report.vi on the Block Diagram, wire in the report type and run it, it gives you this error? Do the example programs which ship with the toolset give this same error also? If so, I would just reinstall the toolset first and see if that helps. It sounds like the entire install is corrupt.

Error Showing While Using Report Generation ToolKit VIs

Hi All,
           When I use report generation VIs Like Excel Easy Tables its showing following errors and i am not able to contiune using the same,
C:\Program Files\National Instruments\LabVIEW 8.2\vi.lib\utility\NIReport.llb\Set Report Font.vi
    - LabVIEW 8.0 changed a constant that was wired to a Case structure to a hidden control to maintain compatibility with LabVIEW 7.1 and earlier.
    - LabVIEW 8.0 changed a constant that was wired to a Case structure to a hidden control to maintain compatibility with LabVIEW 7.1 and earlier.
what might be the issue, i am using LabVIEW 8.2

Hi,
In
LabVIEW 7.1 and earlier, subVIs could be kept in memory by wiring a
constant to a Case structure and placing the subVI in a case that would
not be executed. For example, you could wire a True constant to the
Case structure and place a subVI in the False case of the Case
structure, and LabVIEW would load the subVI along with the calling VI.
However, from LabVIEW 8.0 onwards, the case structure is optimized to remove code that is not going to be executed. Changing the
constant to a control ensures that this VI behaves as it did in LabVIEW
7.1 and earlier. If the intent is not to keep the subVIs in memory, you
can change this control back to a constant by right-clicking the
control and selecting 'Change to Constant' from the shortcut menu. The
proper way to keep a subVI in memory without calling it is to use a
Static VI Reference.
Good Luck!

Step- by- Step on How to Load Excel data into Crystal Reports?

Hi Friends,
Can anyone send me a Step- by- Step on How to Load Excel data into Crystal Reports? Pls help me. Thanks in Advance.
Vijay

It's also important to 'prep' the excel file prior to connecting to it.
Give the data tab a meaningful name
Make sure the column headers are unique and that every column has a header
Delete any blank tabs
If you have trouble with Excel changing the data type of a field (say, a social security number you want to be a string value rather than a number so you don't lose leading zero) an alternative would be to save the spreadsheet file as a CSV, create a schema.ini to specify the data types for each column (example below) and use the same steps to connect except instead of choosing Excel 8.0, scroll to the bottom and choose Text. You have to make sure the CSV file is in the same folder as the schema.ini file that defines the columns.
Schema.ini example:
200912PUSD.csv
ColNameHeader=True
Format=CSVDelimited
MaxScanRows=25
CharacterSet=OEM
Col1=SSN Char Width 9
Col2=LAST_NM Char Width 25
Col3=FIRST_NM Char Width 25
Col4=DOB Date
Col5=STDNT_ID Char Width 10
Col6=SORTKEY Char Width 10
Col7=SCHOOL_NM Char Width 30
Col8=OTHER_ID Integer
Col9=GRADE Char Width 2
The filename in the first line needs to have the [] brackets around it, but I couldn't get it to display in this forum correctly.

Hi,
A trigger is designed to be a part of a transaction, not it's end.
It is like following these steps (not really accurate, but should give an idea):
1. programA issues INSERT statement on tableA
2. 'control' goes over to the database
3. constraint checks happen
4. the associated triggers on tableA do their work (e.g. fetching a sequence value for a primary key)
5. 'control' goes back to programA
6. programA decides if a commit (no error occurred) or a rollback (error case) has to be issued.
Did this help? Probably not, I'm not happy with what I wrote, but anyway... :)

Labview using Report generation toolkit in 2011 run time engine

is that possiblity to run the word in labview using Report generation toolkit in 2011 run time engine

It is possible to use the Report generaion toolkit with the run time engine. But you will have to include a lot of VIs from User lib since the report generation toolkit uses a lot of dynamically called VIs and classses.

Is it possible to insert data into two Excel worksheets using Report Generation Toolkit?

I'm using the toolkit to insert data into two separate worksheets in Excel using named cells. The problem is that it tends to favor one sheet or the other. In other words, one sheet will have data and the other no data and vice versa. (Sometimes I get data in both sheets.) Is there something I can do to clear this up or is what I'm trying to do unreasonable? I would like to use two worksheets so one sheet receives text and data. The other sheet is used to format the data into a printable report. (i.e. using Excel's CONCATENATE function) The second (report) sheet is also used to receive plots (JPEG files) from LabVIEW. I'd send the plot images to the first sheet, but I can
not see a way to automatically transfer images from sheet to sheet. I'm using LV 7.1, Win2000 and Toolkit v.1.0.1

Hi,
You can use the "Excel Get Worksheet.vi" under All Functions >> Report Generation >> Excel Specific >> Excel General to specify a particular worksheet as the current worksheet. Then, you can specify which worksheet you want to write to in your VI.
Let me know if you have any further questions and good luck!
