WD4A: Show Document from client PC

[Former Member]

Hi all,

in my WD4A Application I show document structures from R/3-DMS in a Tree. By clicking a single element I have to show the assigned single document in it's original format (tif, html, txt, doc, ppt ...). Therefor I use RFC BAPI 'BAPI_DOCUMENT_CHECKOUTVIEW2' for checkout documents to a specific path on client PC e.g. 'c:\temp\picture.tif'. But how can I access this file to show it in Webdynpro Popup?

Thanks in advance for your help

Hi,

In case the document was also available on the server, you can use CL_WD_RUNTIME_SERVICES=>ATTACH_FILE_TO_RESPONSE to attach any number of files to a response to a client. The browser will then take care of displaying them.

In case you would like to display documents that already stored at a client PC, there is the possibility to use an iframe, but be warned: The browser applies certain restrictions due to ensuring security and does not allow you to use a path to a file at the user's PC. So using attach_file_to_response is highly advised.

You can find an example in test application WDR_TEST_EVENTS. There, navigate to the button example. In the lower area at the right side there are multiple buttons that demonstrate all the different flavors.

Best regards,

Thomas

Thank you for ayour answer. Have the files on server now. When I work with 'attach_file_to_response' I have to read the file into string area before. Is there another way to read file from server than OPEN + READ/GET DATASET?

I can only think of open dataset for reading actual files. Another option would be to store them inside of a database table (inside of a field of type xstring). While using attach_file_to_response you should rather work with xstring than string in order to avoid codepage issues.
