i am trying to create xlsx file based on block data in oracle forms.
Is it possible to generate xlsx using webutil(Text_io) or by using java beans?
any sample please share me.
thanks

In my opinion and experience it is best using UTL_File to generate text file then open it with Excel. You can use Text_IO also. If I find the example I will post it.

In draw.io there is a very nice option to create a diagram using CSV import utility (Arrange->Insert->Advanced->CSV). It is very simple and straight forward.
I was trying to find a way to do it using an API (REST for example), is there a way to do it?
One more question:
Does anybody knows if there's a way to create draw.io file with multiple pages using the CSV import utility?
Thanks
Danny
Absolutely possible. Working example here: https://github.com/GanizaniSitara/drawio/
pyMX.py you want to have a look at first.
It creates the file in XML then encodes it and packs it into the drawio format.
Needs input data in CSV in format:
Level0,Level1,Level2,AppName,TC,StatusRAG,Status,HostingPercent,HostingPattern1,HostingPattern2,Arrow1,Arrow2,Link
Cool Division,Some Department,Some Department2,SomeString,Zero,25,red,green,0,Azure,Linux,up,up,http://www.gooogle.com
Rinse and repeat for anything else you need to create. It's rough code, ping me here or on GitHub if anything needs clarification.
Is there a place to find sample CFD data in this format please?
I am trying to create scripts for Paraview to automate files opening and want to use the track function.
Data from this article can be used to test out the file format:
how can I create file (PDF file for example) from binary stream I have stored in global? I have stream stored in caché global and I need to create and save the file created by the stream using ObjectScript.
Thanks :)
It is not so easy. There is only one official way to create pdf in Cache, and it is ZEN reports. With ZEN reports you could create not only pdf, also possible to make html, xlsx. ZEN Reports used Apache FOP for generating it, any other ways also possible, but you should do it only by yourself.
Or maybe I misunderstood you, and you mean that your binary stream already contains PDF, and you just want to save it to some file. If so, you just have to copy your globalstream to filestream, with code like this:
set fs=##class(%Stream.FileBinary).%New()
set fs.Filename="c:\temp.pdf"
set tSC=fs.CopyFrom(yourStream)
set tSC=fs.%Save()
Is it possible to create PDF documents (e.g. on a nightly schedule) with Tableau and have those documents exposed by a URL by the Tableau server?
This sort of approach is common in the Jasper Reports and BIRT world, so I was wondering if the same approach is possible with Tableau?
I couldn't see any documentation on the Tableau site for creating PDFs, other than print to PDF
With Tableau Server, you can access your published workbook in a pdf format with this URL:
http://nameofyourtableauserver/views/NameOfYourWorkbook/NameOfYourView.pdf
Simply, the url is the url of your view + you add ".pdf".
The pdf file will be generated dynamically when accessing the URL.
Another option is to program your own script with tabcmd.
You can have more info on tabcmd here: http://kb.tableausoftware.com/articles/knowledgebase/using-tabcmd
The same technique also works for PNG. You can control filters using ?field_name=value. You can even select multiple values like this ?field_name=value1,value2.
Parameters can be set the same way.
Personally I've had the best luck with discrete dimensions instead of continuous ones.
I use the Windows Task Scheduler with batch files and Tabcmd.
Programs needed:
Tabcmd
Windows TaskScheduler (All Programs- Accessories - system tools)
http://onlinehelp.tableausoftware.com/v8.1/server/en-us/tabcmd_overview.htm
(tabcmd, how it works?)
Batchfile (create a text file and then save with file extension .bat):
1- Locate tabcmd and login
2- use function tabcmd get "http:\..." and -f "C:...pdf" to save to file.
3- concatenate the filters you want to use to the end of your URL as shown in other answers(all filters on the view must be included(filled out))
4- Save Batch file
Windows Task Scheduler:
1- create a task that will execute the batch file
2- TEST
You can do this by typing
http://server/views/WorkbookName/SheetName.pdf?:format=pdf
Another option will be using javascript api like below..
function exportPDF() {
viz.showExportPDFDialog();
}
I came around this technique of converting datatable to excel
http://www26.brinkster.com/mvark/dyna/downloadasexcel.html
Do we have any Equivalent of Response.AppendHeader in windows application in C#.

The trick in the code sample that you have mentioned to dynamically generate an Excel file is based on the fact that documents can be converted from Word/Excel to HTML (File->Save As) and vice versa. Essentially a HTML page containing Office XML is created & in a web application a file download is triggered with the help of the following Response.AppendHeader statements -
Response.AppendHeader("Content-Type", "application/vnd.ms-excel");
Response.AppendHeader("Content-disposition", "attachment; filename=my.xls");
If you want to use this technique in a Winforms application, just save the string content as a text file and give the file an extension of ".xls". Instead of the last 3 lines in the sample's Page_Load method, replace it with this line -
System.IO.File.WriteAllText(#"C:\Report.xls", strBody);
