Web Server - Ask For Help / NetRefresh
« Last post by rjolda on October 31, 2025, 01:47:14 AM »HI
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

Web Server - Ask For Help / Re: Uploading files loc:AcceptTypes
« Last post by rjolda on October 19, 2025, 12:43:10 PM »Solved,
'application/jpg,application/png,application/pdf' is the syntax. However, this will limit the files to pick from to those file types.
The user can use "All files' and upload something else. So, they can get around it.
This is where the code above from Osquiabro comes in. If someone overrides the suggested file types and actually uploads something like a BMP file, then his code will intercept it and delete it with a message.
