xDeviceFileWrite and VLWEB SP2
Posted: Tue Jul 03, 2018 4:17 pm
I've asked this question before but I can't seem to find the thread. I'm sure there was something in there about SP2 facilities.
I have a Server module which returns a list of images as BLOBs. I want to show them in a HTML Container. My application is running on an ipad within Longrange. I think I should be able to do this by saving the blobs to local storage using xDeviceFileWrite and referring to them using '<img src="file:///' but I don't know if this is possible.
I don't know what the xDeviceFileWrite properties DataEncoding, FileType and FileEncoding should be to save the file.
I think there was a reference to storing it as base64 and using src='data:image/jpeg;base64' so I could convert my BLOB to a big string and use this method (ie don't use xDeviceFileWrite ) but how do I convert a BLOB to string?
