Hi,

How are people copying files (images or other files) from Appeon Mobile apps to their server?

I am trying trying to use UPDATEBLOB to store the image in the database but the below code is throwing the following error: "Error Code: 10999. Object refrence not set to an instance of an object" at the insert statement. This statement works from PB Desktop without issue.

String 	ls_filepath
Integer 	li_return
blob   	l_blob_file
int    	l_file_handle
eon_mobile_str_cameraoption lstr_option
eon_mobile_cameraex ln_camera

lstr_option.i_filetype = 1 			// Photo
lstr_option.b_allowedit = FALSE 		// The photo is not editable after picture-taking

ln_camera = create eon_mobile_cameraex

ln_camera.of_openalbums ( ls_filepath ) // i also tried ln_camera.of_openalbums ( ls_filepath, l_blob_file)
MessageBox('',ls_filepath)

l_file_handle = FileOpen(ls_filepath, StreamMode!)

MessageBox('','Handle: ' + String(l_file_handle))

IF l_file_handle  0 THEN
	COMMIT USING SQLCA ;
Else
	MessageBox('Error','Cannot insert blob to database')
END IF

p_1.picturename = ls_filepath // this works

I was hoping to avoid using the File Upload and Download feature due to how our client's internal servers are setup. Don't want to have to recopy the file from the Appeon Server machine to another machine etc. but if this is the only way it can be done... Ideally I'd love to be able to upload it to a SOAP Webservice using a byte array but I've had issues doing this too.

Is it possible to use UpdateBlob like above (connecting to a ms sql database) or can anyone spot why this is failing.

Thanks,
Alan
