Web Server - Ask For Help / Api endpoint stream - how?
« Last post by Niels Larsen on May 18, 2025, 10:34:25 PM »
Hi
I am developing an endpoint where I have to stream a pdf file (actually I have it as BASE64).
But I need some help to get going with the stream itself.
This is what I have from the associated Swagger:
Code: [Select]
  stream:
    type: object
    properties:
      canRead:
        type: boolean
      canWrite:
        type: boolean
      canSeek:
        type: boolean
      canTimeout:
        type: boolean
      length:
        format: int64
        type: integer
      position:
        format: int64
        type: integer
      readTimeout:
        format: int32
        type: integer
      writeTimeout:
        format: int32
        type: integer

Can one of you wise heads help me out?

Regards Niels

Hi Ron,

Thanks - that got me going.
Had an issue still getting an Record Not Found error when loading form B, until I added this code in the InitForm Routine:

Code: [Select]
p_web.SetValue('MCus:CUSTOMERNO',p_web.GSV('MCus:CUSTOMERNO'))

Hi Poul,
Are you going to use a Button to call Table B Update?
On the Button Code - "On CLick" - you can call the Update PROCEDURE for Table B here.  You can set any Parameters to pass to Table B on the next line.  Lastly the last check box "Include Action" you can check and set the action to Insert, Change as appropriate.  That is where I would start.

Web Server - Ask For Help / Call a related table update form (SOLVED)
« Last post by Poul Jensen on May 16, 2025, 03:11:42 AM »
Hi,

From a button on the update form of table A, I would like to call the update form of a related table B.
On the button > Client-Side > Send new value to server, I get the record of the related table B (and verifies with debugview++ that it is the correct record) but I have no luck with calling the related update form.

Have tried various variants of code hacked from table B's browse, but without success.  See code below:

Code: [Select]
    DO OpenFiles
    !Get record of table A
    Access:MobSagH.ClearKey(MSagH:KeyGUID)
    MSagH:GUID =  p_web.GSV('MSagH:GUID')
    NOMEMO(MobSagH)
    IF Access:MobSagH.TryFetch(MSagH:KeyGUID)
        !failed
    ELSE
        !Get record of table B
        Access:MobCustomers.ClearKey(MCus:KeyGUID)
        MCus:GUID =  MSagH:KundeGUID
        NOMEMO(MobCustomers)
        IF Access:MobCustomers.TryFetch(MCus:KeyGUID)
            !failed
        ELSE
            ds_outputdebugstring('RET KUNDEN - **OK**  MSagH:KundeGUID: ' & MSagH:KundeGUID)
            p_web.SSV('MCus:CUSTOMERNO', MCus:CUSTOMERNO)       

            !This doesn't work
            UpdateMobCustomers(p_web,Net:Web:Popup)  !Form Procedure
                   
        END
    END
    DO CloseFiles

What am I missing here?

Hi,
That code looks like it will do just exactly what I need it to do.
Will check it out.
Thanks,

I have a button that rotate a image with ImageEx
 
If ThumbImage.iImage.Load(p_web.GSV('Loc:Path'))
    ThumbImage.iImage.Rotate(90)
    Loc:GuidFoto = st.MakeGuid() 
    ThumbImage.iImage.SaveAs(st.PathOnly(p_web.GSV('Loc:Path'))&'\'& clip(Loc:GuidFoto)&'.'&st.ExtensionOnly(p_web.GSV('Loc:Path')) )
    Loc:Path = st.PathOnly(p_web.GSV('Loc:Path'))&'\'& clip(Loc:GuidFoto)&'.'&st.ExtensionOnly(p_web.GSV('Loc:Path'))
    p_web.ssv('Loc:Path',Loc:Path)
    p_web.SetSessionValue('_save_Loc:Path',Loc:Path) 
    p_web.SaveFileToSession('Loc:Path','Mem:Foto')
   
   
End
loc:st_filename = '/uploads/'&clip(Loc:GuidFoto)&'.'&st.ExtensionOnly(p_web.GSV('Loc:Path'))
p_web.ssv('loc:st_filename',loc:st_filename)

try
    p_web.HeaderDetails.ContentDisposition =  'attachment; filename="'& CLIP(Loc:DownloadFileName) &'"'
    p_web.HeaderDetails.CacheControl = 'no-store, no-cache, must-revalidate, private,post-check=0, pre-check=0, max-age=0'


Thanks Bruce - this did it.

I think you're over thinking this.
The Take Photo button takes the photo, and sends it to the server.
So you can process it however you like on the server.

The browser really only needs to update the displayed picture after processing.

We can chat in the webinar if you need more ideas.

Cheers

first you need to determine if it's coming from the local client cache, or the server cache.
(Both the browser, like Chrome or Edge) and the NetTalk server can cache files.

There are headers you can set when serving the file to indicate it's uncacheable. (You can google for that if you like, or look in netweb.clw.)
Alternatively you can alter the URL - by adding a random parameter. For example;

capesoft.com\somefile.saf?r=123
is different from
capesoft.com\somefile.saf?r=321

So simple by adding a parameter (which the server happily ignores) with a random value, the client won't get it from cache.
Obviously though it depends on how they are seeing the URL in the first place to download the file.

Cheers
Bruce
