Web Server - Ask For Help / NetClient.Send error??
« Last post by rjolda on Today at 02:36:56 AM »HI
NT 14.36 C11.
I added NetRefresh to my NT app. Now when I Save an Update to a record, I get the following error message:
A nettalk network communication error has occurred.
Error = Anerror occurred while attempting to send a packet from service.
The error number was -12 which means you are trying to send data to someone who is not in the receivers (servers) list.
Error occurred in function (parent) NetClient.Send
ServiceName = (blank)
Can anyone shed some light on this? My NetRefresh is not working correctly and maybe this has something to do with it?
Thanks,
Ron

BT14.36 C11 ABC
I am starting to play with NetRefresh. I have a case where user B is watching a NT BROWSE on table called J_SRVREQ. This Browse is set in NetRefresh Local Extension to Refresh table J_SRVREQ and sending J_SRVREQ.
I have a client who INSERTS a record into table J_SRVREQ. The client is set to Refresh J_SRVREQ. Insert is done using the UPDATE for this table but it is called in code and not from the Browse.
I would think that anyone then watching J_SRVREQ with a NTBrowse which is open (user B) would see that a record was added and NetRefresh would kick in and REFRESH the NTBrowse on J_SRVREQ for any user that has this table open and is using NetRefresh.
However, after client creates a new record for J_SRVREQ, the NTBROWSE on J_SRVREQ is NOT UPDATING - I have to do a manual refresh to see the new inserted record.
What am I missing to tell the user B that the Browse needs to be refreshed when a record is added?
Thanks,
Ron

Web Server - Ask For Help / Re: Use DRAW to Create QR Code in NT app?
« Last post by rjolda on October 30, 2025, 01:30:02 PM »Hi, got the answer from NT User Group. Short answer - you need an image field for QR to work its magic.
I created a window and added the QRCODE template ( that put an image on the window for QR Gen to use. I am passing p_web to the procedure so I pass in my QRTEXT and QRSaveFileName and call the QR_Window, generate the QR CODE, Display it and save it and close the widow and save it and return to my NT procedure. works great.
I will have to try the method Osquiabro described.
Thanks Osquiabro and Don,
Ron

Web Server - Ask For Help / How to use webfonts, etc. on web app button?
« Last post by jking on October 30, 2025, 08:20:05 AM »Hello all,
I'm trying to improve the icons/images on a NT 14.30 web app. In the template, Button tab, there are fields for Icon and Image. I have successfully used a few image files, in the image field, such as 'images/search.png'. However, I tried to use 'calendar large' and 'calendar xlarge' in the icon field, to use a Webfont icon. Both are the same size and very difficult to see. Any suggestions? Other font sets I might add that work better?
Thanks,
Jeff King

« Last post by DonRidley on October 30, 2025, 04:20:53 AM »Good day Ron,
If you take a look at the NetTalk webserver Insight Graphing example's WebGraphSize procedure you will find:
The important parts are:
ThisGraph2.SaveAs:
SaveAs uses draw to create the image that is eventually displayed using p_web.CreateImage.
Now, this is one way to approach this. You could use this method to generate a QR code image and display it but you're going to run into the main problem I have with Insight graphs in a web app...resolution.
If you want a higher resolution image with this approach you'll need to make the container Window larger and the image control larger which creates a larger image. The larger the image file then the slower the HTML page loads.
So, this is a long winded way of saying that I suggest you use a JavaScript approach using jQuery.
Here's a link to a jQuery plugin for QR codes:
https://github.com/jeromeetienne/jquery-qrcode
I think this would be a better way. Generate the QR code client side.
That's my humble opinion.
If you take a look at the NetTalk webserver Insight Graphing example's WebGraphSize procedure you will find:
Code: [Select]
If not p_Web &= NULL
loc:silent = p_web.GetValue('_Silent')
p_web.DivHeader('WebGraphSize_2','nt-left')
If loc:Silent = 0
Window{prop:hide} = 1
ThisGraph2.Reset()
ThisGraph2.DrawGraph()
ans = 'images\@@@' & format(random(1,99999),@n05) &'.png'
ThisGraph2.SaveAs(clip(p_web.site.WebFolderPath) & '\' & Ans)
Window{prop:pixels} = 1
packet.append(p_web.CreateImage(ans,ThisGraph2.Width,ThisGraph2.Height,ThisGraph2.HeaderName))
End
p_web.ParseHTML(packet,1,0,NET:NoHeader)
packet.SetValue('')
p_web.DivFooter()
Return(Level:Notify)
End
The important parts are:
Code: [Select]
ans = 'images\@@@' & format(random(1,99999),@n05) &'.png' !<<--- Path string to an image file is create
ThisGraph2.SaveAs(clip(p_web.site.WebFolderPath) & '\' & Ans) !<<--- Actual image file is saved to the path
packet.append(p_web.CreateImage(ans,ThisGraph2.Width,ThisGraph2.Height,ThisGraph2.HeaderName)) !<<--- HTML for the image is generated
ThisGraph2.SaveAs:
Code: [Select]
InsightRoot.SaveAs Procedure (string FileName)
f string(255)
code
if self.thisDraw &= null then return . ! ghnn
f = filename
if instring('.',lower(f),1,1) = 0
f = clip(f) & '.png'
end
if instring('.wmf',lower(f),1,1)
elsif instring('.bmp',lower(f),1,1)
Self.ThisDraw.Writebmp(f)
elsif instring('.png',lower(f),1,1)
Self.ThisDraw.WritePng(f)
end
SaveAs uses draw to create the image that is eventually displayed using p_web.CreateImage.
Now, this is one way to approach this. You could use this method to generate a QR code image and display it but you're going to run into the main problem I have with Insight graphs in a web app...resolution.

Web Server - Ask For Help / Use DRAW to Create QR Code in NT app?
« Last post by rjolda on October 29, 2025, 12:19:02 PM »Hi,
NT 14.36 C11.0136
I want to generate a QR code with DRAW. I am currently doing it with ezCam but if I can do it with DRAW it will be much cleaner.
PROBLEM. DRAW requires an Image. I have tried creating QR without the Image on a window and it does NOT work.
If I place an IMAGE on the window, I have to DISPLAY the image and then I can write it to a PNG file.
The documents state that displaying the image is optional- however, If I don't display the image, it will not save ( save writes a black square ).
Anyone with insight?
Do I have to try to write it to an Image file in NT first?
Thanks,
Ron
