The workbook object has a "Sheets" property that returns a collection of all
the sheets in the active workbook. Use the "Item" method on this collection
to select the sheet you want- if necessary by cycling through all the
elements (use the "Count" property to find how many objects there are) and
using the "Name" property to get the name of the worksheet for comparison
with the one
you're looking for. Remember that everything is case sensitive.

Problem with exporting a report to excel vial citrix server

Hi,
We are encountering a problem with exporting a report to excel through ALV local file icon.A spread sheet is downloading only one row (From header) instead of many rows from the ALV output .
Above is working fine for the GUI installed on my PC, but not throgh the Citrix server.
Can any body have idea on above mentined?

I understand that you're trying to download the file to a local computer through Citrix. In this case you need autorizations in Citrix for your user ( CItrix user)

Problem with solver DLL load and Excel 2010

Since upgrading from Office 2007 to Office 2010 we've started to experience a problem with the solver addin when our own analytics addins is also loaded. I have found a solution, but I think it may highlight a problem with the latest version of the solver
addin for Excel 2010.
Firstly, to describe the problem - the solver addin seems to load normally when Excel 2010 starts up, however when a "Solve" is performed we are seeing a "File not found: Solver32.dll" error at the final "Keep Solver Solution" stage. This only happens our
own analytics addin is loaded. We've been careful to make sure that our own addin does not change the working directory and also that it has been built against the correct Excel 2010 SDK libraries. We do not see this error with any other versions of Excel
running on the same PC or any other environment.
After some searching we found other people were having similar problems and after a bit more probing I found a solution that works - but that I'm not very happy with.
If I copy the Solver32.dll from:
C:\Program Files (x86)\Microsoft Office\Office14\Library\SOLVER
(where it was installed)
into :
C:\Windows\SysWOW64
(where Windows 7 keeps its 32 bit system DLLs)
then the problem goes away.
This seems to indicate that somehow Office 2010 has a problem that causes it to search in the wrong folder for the Solver32.dll when another addin is loaded in between the original Solver32.XLAM at start up and the use of the Solver in the sheet (which eventually
requires this DLL to be loaded). Oddly, this only happens after a solution is found and "Keep Solver Solution" is selected - and I'm not sure why it's not looking for Solver32.dll any earlier.
This is not a problem with any earlier versions of Excel and I suspect is a bug in the Office14/LIBRARY/SOLVER implementation. Is there any way to get this followed up?
Thanks,
Andy

Problem with thousands and decimal separator (Excel 2000)

Hi, i have a problem with the download option to excel 2000.
When downloading numbers over 1000 the thousands separators change in decimal separators.
My config is:
Locale (location): Español - España
User Interface Language: Español
For example, if I have a value as 1800:
1) in OBIEE show "1.800" (ok)
2) in Excel 2000 show "1,8" (bad)
If i choose Locale (location): English - United Stated and
User interface language Español.
1) in OBIEE show "1,800" (bad)
2) in Excel 2000 show "1.800" (ok)
Can someone help me solve my problem?
I need to show the same result in OBIEE and Excel, that is, "1.800" with "." not with ",".
Thanks

Hi,
The thousands separator change in the backend dind't work. (+ it only works for text input fields, not for text fields)
Anyhow, this is how we created a workaround :
Suppose we did this : NSTR(@CREDITLIMIT,"C.2")
This resulted in the field being displayed as 67,234.56
The 'dirty' way to convert this to an european format is :
REPLACE(REPLACE(REPLACE(NSTR(@CREDITLIMIT,"C.2"),",",";"),".",","),";",".")
Output is 67.234,56
(we just replaced the '.' by ',' and vice versa)
I still feel quite uncomfortable with this solution, but this is the only way we got it to work.
I really hope a next patch/servivepack provided a more elegant solution for this problem... (hint hint)

Problems with Java Dictionary Tables

Hi Experts,
I have some problems with the Java Dictionary tables that I have created for my
application. There are around 15 dictionary tables, each one of them having
several hundred records, added in due course.
As much as I understand these tables (created using the dictionary perspective)
are stored in the default schema of the J2EE engine where the dictionary project
is deployed and there is no direct way to insert records into these tables, we have
to separately write methods to insert, update and delete records.
I've already done this. Now the problem is that i have moved my project DC from
development to testing. Now here the tables are existing, but not the data that i
inserted during development.
NOW, the main question: IS THERE ANY WAY IN WHICH I CAN TRANSFER
THE CONTENTS OF THESE JAVA DICTIONARY TABLES??
I have tried solutions like creating a DBLINK between the databases, but it is
tedious, and unpredictable in behaviour. Also Please do not advise to first
download them to excel and then upload using jxlapi, etc.
Thanx in Advance.
Alka.

Hi Alka,
The dblink is a good solution, but just a bit slow. You can also use a SQL Loader, first export the data from the source table in a text file (i.e. using a tool like TOAD), then sql loader loads the data in the destination table. This is more fast.
Hope this help,
Vito

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
Attachments:
sample 5.vi ‏35 KB

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.

Problem with output from report to excel, calling the report from form 10g

Hi everyone, I'm having a problem generating a excel from a report, which is called from a form, I'm using Forms 10g. The problem is this: My report has a variable number of columns. These columns appear according to data obtained from the database, these columns are dates, In vesion 6 excel file generated shows the columns one after another starting in column A1 to column CP. I mean that the dates are correlative. But in version 10g the excel file generated shows the same report starting in column A to column T, only shows the 20 dates correlative corresponding to this columns, the rest of the dates are down the excel sheet in groups of 20 dates, it's something, the file in 6i grows across and in 10g grows down the excel sheet. The report (rdf file) is the same in 6i and 10g, I compiled the 6i version to obtain the 10g version. The excel sheet generated in 10g looks like the report was in pdf format, because PDF format, cuts the report in pages and the file grows down, if I generate the report in PDF format it has the same structure excel file in 10g has. I hope yo can help because I have days trying to solve this but I have no succes. If someone could help I could email the excel files generated in two versions. Here I put the code I use to generate the files in 6i and 10g. I have tried with DESFORMAT=SPREADSHEET in 10g but the result is the same. Thanks for your help. Greetings for all.
Code for version 6i (Works Very well)

Problem While exporting HTML table to Excel(.CSV) in SharePoint 2010

Hi ,
I was exporting HTML table to .CSV file.
Problem is if any field contains '>' or '<' symbol then after exporting to .CSV, it was showing like '&gt' and '&lt' and the code is as below.
//Export HTML table to CSV
function toCSV() {
var data = document.getElementById('reportstable');
var csvData = [];
var tmpArr = [];
var tmpStr = '';
for (var i = 0; i < data.rows[0].cells.length; i++)

csvData.push(tmpArr.join('\t'));
for (var i = 1; i < data.rows.length; i++)
tmpArr = [];
for (var j = 0; j < data.rows[0].cells.length; j++)

Thanks in advance.

Hello shaheen,
yups i have same problem here.See if you try to open up your XML output
in MS- Excel 2003 version (11.8117.8107 OR later ) SP2 you will face problem beacuse excel will not ask you for wherther you want to open file as "XML LIST".But my colleague in diffrent country they have version 2003 (11.5612.5606)
you can see its not the latest whenever they open downloaded file,excel ask them to open in "XML LIST" and output is perfect.So i guess its problem with EXCEL.

Problems with write to measurement

My project group has some problems with the write to measurement VI.
Firstly, for each of the SOC/Voltage...each file only has one value, how to make all value inside one file?
Secondly,How to make all the different parameters, such as SOC1, SOC2, Voltage1, Voltage2, appear in one excel file for easier reference?

Look at your settings for the Write to Measurement File. You are telling it to save to one file, and then use next available filename. Try append to file.
Also, use Merge Signals to combine the 4 and write to a single Write to Measurement File. Right now you have 4 identical ones with the same file name. They are stepping all over each other.
When using the Write to Measurment File, try opening up the help file and reading it o understand what each setting does.

Problems with calculation in table footer

I’m working on a 'dynamic form’ with an expandable table (i.e. the user presses a button to add a new row), there are cells in each row for beginning month & ending month, plus an autocalc total field containing the formula: “ending – beginning +1” (which accurately calculates total months e.g. Jan-Dec = 12 months). There is also a ‘total months’ field in the footer which sums the row ‘total’ cells. The problem I have is that the user could add a blank row throwing off the total cell in the footer. Any suggestions to accomplish my goal of presenting accurate total in footer while ‘idiot proofing’ the form?

Problem with loading fact table in OWB3i

Hi,
I have a problem while trying to load a fact table using OWB 3i. Let me explain the situation :
I have 2 dimensions: Customer, Product say.
I have loaded the dimension tables separately, successfully using different mappings from source tables.
Now I want to load the fact table with the corresponding warehouse keys from these dimension tables through lookup transformation.
When I try to bring to lookup transformations for the 2 dim. tables, it gives an error--"Source and target are bound to different data providers". Using 1 dim table and 1 corresponding lookup transformation , the fact table is successfully loaded.
How to load a fact table when there are more than 1 dim. tables using lookup ?Is there any other way of solving the same problem?
Any suggestion will be highly appreciated.
regards
Dipanjan

Simply, try joining source tables with the join operator. In wich way you can create a single source object into the mapping suitable to be connected with yours fact tables.
Greetings
