Web Server - Ask For Help / Re: Use DRAW to Create QR Code in NT app?
« 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.

Web Server - Ask For Help / Re: Child browse reading primary key from multiple tabs in NWB
« on: June 22, 2023, 02:45:33 AM »
Following Bruce?s idea..
You could use buttons and then use CSS to make them look ?like? tabs. I would spread them across the top of the browse perhaps.

« on: June 12, 2023, 04:41:21 AM »There isn't any hand-coded or added HTML. It's all Wizard generated.
Trust me. Check your HTML.
I'm not saying the wizarded procedure was generated wrong. I suspect it is attempting to display exactly what is in the database.
Right click on the browser on that offending browse and select "view source." Any incorrect HTML code should be red if I remember correctly.
Like I said...trust me.

Ubaidullah,
I would debug your HTML.
The fields in question may be causing an error in your HTML which would cause your browse to stop working on that particular page of records.

I "think" he's talking about a fixed header. Like:

But I could be wrong.

Web Server - Ask For Help / Re: String Teory Question
« on: January 04, 2023, 03:42:49 PM »
When you do st.Load() in StringTheory you can then use st.Length().
st.Load() calls this Win32 API (along with others):
stGetFileSize(long hFile,*long SizeHigh), long, pascal, name('GetFileSize')
https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-getfilesize
Just tested loading various files into the StringTheory demo. Seems st.Length() after st.Load() will do what you need.

Hello Matthew,
I like your demo site. Nice and clean interface.
I would be interested in learning more about your approach to handling sessions.

Web Server - Ask For Help / Re: Larges Reports on NT
« on: December 22, 2022, 04:56:01 AM »
I don't see why you couldn't.
You could say that any file larger than x megabytes would trigger a "long" process.
Then in your user interface, notify the user that the report will take a while to process and that they will be notified when the report is ready for download.
Report process runs on its own thread.
When it's finished, file would be saved to a folder visible to the web server.
Then create a link to the file and email or SMS it to the user.
