Real Software Forums

Good morning, I am new to this forum and still no expert Real Studio.
Who can help me with this, I'm trying to view PDF files from Oracle. The field BLOB store. I can find the object, since the list box does not give me the name of the stored documents.
Greetings ...

Write the blob data to file and use folderitem.launch (setting the folderitem to the path of the temporary pdf file)...you will have to create a name for the pdf if that information is not stored in the database...

ex....

write the pdf blob to SpecialFolder.ApplicationData.Child("tempname.pdf") (or somewhere else) then

SpecialFolder.ApplicationData.Child("tempname.pdf").launch to open it.

this would be the most simplistic method.

Thanks for answering.
But to display the PDF file, I show a WebImageView? Or open the PDF reader installed on my system ...
I will do as you comment and I will report the results.
Good day.

using the command .Launch will load the pdf in the default system reader...webimageview is a web edition class which is the web equivalent of an ImageView (desktop apps)...Neither of which will help you at all... to save the blob...

'load the blob into a string using the blob.stringvalue. To save it....

Dim SavetheFile as new TextOutputStream
SavetheFile = TextOutputStream.Open(folderitemdeclaredTMPPDF) ' replace with the actual FolderItem
Savethefile.Write theStringValueofTheBlob
SavetheFile.Close

'now lets open the PDF....
folderitemdeclaredTMPPDF.Launch 'as before, replace the first part with the actual folderitem of the PDF file above

Is it a web app or a desktop app? The answer will be different for each.

I was going to ask the same thing but noticed it was in the windows section so assumed it was a desktop app

It may be worth looking into our DynaPDF Pro plugin for Real Studio.
It can render PDF pages. For a Web app you could render directly to JPEG and create a Webpicture from it.
For desktop you can render to picture and draw it in a canvas.

Thanks for your answers ... From the outset I should clarify that I'm working on a web application. An apology.
I will do what you said Simulanics, because the canvas or ImagenView I can not watch it.
Thank you for your help.

I want to display as the example of MonkeyBreadSoftware is at the following link http://webapps.monkeybreadsoftware.de/webpdf/webpdf.cgi. That's exactly what I do. Only if you can, without the plugin DynaPDF of MBS.

I have included a desktop demo of how to read and open pdf's...the same can be employed using the webHTMLViewer and you can use a javascript to check to see if a user has adobe on their system or use an open source javascript (ie https://github.com/mozilla/pdf.js/) which will load a pdf in the window without any requirements...if you need help implementing this...send me a message and will be glad to get an example working with a re-usable module and/or custom web control

the desktop demo is at

here is the web demo with using HTML5 only

SIMULANICS Thanks, I will verify what I said and I will report results.

Good morning to all. I still have problems creating the page to show me PDF's files. All I got was with their help to open the PDF file, but with the reader system. And so the user can save or copy the contents of the document and that is precisely what I want to avoid.
I'm performing them as an image, but is more complicated.

I'll work on embedding the PDF html5 javascripts I recently posted into a direct custom webControl for you have a 14 hr ride today, so I'll have plenty of time to work on it

This may also be an alternative if you cannot wait

Thanks SIMULANICS, I'm seeing the links placed. thanks ..
