Good afternoon, I am showing images from a table with a DB Blob object in a
Datawindows and in Client-Server mode it works without problems, but when deploying web
the datawindows does not show the images, do you know what it could be? ?

Are you using TableBlob to display it?  Per the PowerServer documentation, this is an unsupported feature:  https://docs.appeon.com/ps2020/features_help_for_appeon_web/Controls_in_a_DataWindow_and_their_properties1.html#d0e94672

You would need to workaround or wait for PowerServer 2021.

Hi Andres;

One "workaround" that Armeen hinted upon would be to perform a SelectBlob command, write the blob data to an external image file and then assign the image file to a Picture control or map it to a DW column with the "display as picture" property turned on. HTH

I already used that modality with selectblob, but when performing the web implementation and testing it doesn't work,

Because when downloading the images, a physical path is required and the data window does not show the images, but it does on a client server.



Please help to solve this, thank you very much

Hi Andres .. FYI: In Web and Mobile Apps, you need to use the path as returned by using the " of_getcachedir ( ) " method. Please see the PS Help for more information on this feature. Regards ... Chris
