Hi Christiano

Thanks for your reply - I'm not sure how to go about doing that. So, if I had a .PNG how would I display it on a zen page?

Andy

That was very helpful. Thanks for posting.

Hi Cristiano - that worked perfectly. Thanks for replying.

That worked perfectly, thanks. One last question, where would I find style sheet information to colour the results as per the HL7 viewer does?

That's perfect. Thanks for taking the time to reply.

Thanks again, that's perfect. Thanks for all your help.

Hi Jeffrey - that's perfect, thanks for taking the time to reply. Once last question: do you know how I might locate information on the Arbiter connection status?

Andy

That's perfect. Thanks for taking the time to reply.

I solved it.

I changed to OnPage() method to use a %Stream.FileCharacter as follows:

ClassMethod OnPage() As %Status
{
	
	set fs = ##class(%Stream.FileCharacter).%New()
	set fs.Filename = %request.Get("filepath")
	
	do fs.OutputToDevice()
	quit $$$OK
}

Hi there! Thanks for taking the time to reply. I implemented the above code and was quickly able to download the file in question. However, the PDF files that is downloaded doesn't have the same size as the original - in fact all are 5Kb smaller, e.g.197Kb downloads to a 192Kb file, 241Kb to a 236Kb etc

I modified the OnPreHttp() method to set content length, but that had no effect.

/// Set the appropriate header for the file.
ClassMethod OnPreHTTP() As %Boolean
{
set filepath = %request.Get("filepath") set tFs=##class(%Stream.FileCharacter).%New()
set tFs.Filename=filepath set %response.ContentType = "application/pdf"
do %response.SetHeader("Content-Disposition","attachment;filename="""_$P(filepath,"\",*)_"""")
Do %response.SetHeader("Content-Length",tFs.Size)     Quit $$$OK
}
 

Do you have any ideas?

Thanks for the warning. Fortunately, this is for a internally hosted page accessed by username/password only by authorised operatives.

I solved the problem: user error! One of the variable values was misspelt in the database. Thanks for taking the time to answer!

OMG! I can't believe I didn't notice that. Thank you for this!

After further experimentation, I have found that entirely omitting the where clause causes only 1 value to outputted in the second loop that examines the cursor.

I have added that, but it had no effect. Thanks for taking the time to reply though.
