Web Server - Ask For Help / Re: Avoid downloaded file been served from browser cache
« on: May 13, 2025, 06:44:16 AM »
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.

Not sure if this is helpful - but see NetDemo, NetWebClient, "Secure HTTPS Options" tab, Client Certificate option.
If you can get it working from there, you'll be golden.

Web Server - Ask For Help / Re: NetWebServiceMethod as REST - HOW?
« on: May 04, 2025, 09:50:26 PM »
>> But the customer wants it like this:
http://127.0.0.1/WasteInvoice/InvoiceOverview/account/{accountId}/customer/{customerId}
Have you told him how much extra that pattern will cost? I find that putting a price on it lets you determine how much they "actually want it".
>> Does that make sense?
yes.
To do this though you will need to parse the WholeURL yourself, likely in webHandler, setting the values as you interpret them (ie with a call to SetValue).
It's not terribly hard to do, but obviously is a custom approach to both parsing the values, and then redirecting the request to the correct API.
For example, in this URL I presume WasteInvoice is the name of the NetWebService, and InvoiceOverview is the name of the NetWebSericeMethod.
You *may* find it parses that sufficiently to get the call into the NetWebServiceMethod procedure, or you may need to parse it in webHandler.
Once you are in the method, you can then parse the URL further to find the account and customer ID. That's pretty easy to do with StringTheory etc.

Web Server - Ask For Help / Re: Refresh NWB Header
« on: April 25, 2025, 10:46:32 PM »
ahhh - so when you said "the browse header" you meant in a routine that you happened to name "header".
A small detail, that probably matters with regard to the answers.
The item you are updating in this header, is it specific to this user, or common across all users using the server? It seems like it's a value unique to this user?
Your best option is to make a small example app showing what it is you want to do, and I can look at that and suggest something from there...

« on: April 16, 2025, 06:45:26 PM »
p_web.StoreValue('a')
Is the best way to set a session value to a value, because then if the value doesn't exist (as a parameter) it does not overwrite the session value.
I expect you are just overwriting your session value to blank when the value does not exist.

Web Server - Ask For Help / Re: NT Maps - update calling different table/record
« on: March 24, 2025, 10:07:48 PM »
depends if the page is in popup mode or page mode.
You can't set a parameter easily from the Map side, since it's called directly from javascript, but you might be able to set a parameter on the browse side. And then check for that parameter (GetValue) in the form.

« on: March 23, 2025, 11:28:36 PM »
>> the approach of having a second update form on the update form for the point record, is that a good approach?
no.
A better approach, one that will work, is to call the form you want to call. In the example you sent me that would be UpdateUser, in your real app I expect it's UpdateJob, or whatever.
So now the issue is getting the correct record loaded in that table. I'll refer to the example you sent - the map is plotting the accidents, but you want to UpdateUser. So in UpdateUser, in the InitForm routine you need to prime the GUID value of the user to edit.
At this point all you have is the sesison value for the Accident. So the code goes something like this;
Access:Accident.Open()
Access:Accident.UseFile()
Acc:Guid = p_web.GSV('Acc:Guid')
Access:Accident.TryFetch(Acc:GuidKey)
User:Guid = Acc:UserGUID
Access:Accident.Close()
p_web.SetValue('Use:Guid',Use:Guid)
p_web.SetSessionValue('Use:Guid',Use:Guid)
This loads the Use:Guid into the Value, and SessionValue queues, and from there the form can take over.

Web Server - Ask For Help / Re: web26 example File Upload
« on: March 23, 2025, 09:56:01 PM »
The example is confused by the existence of the Doc:Name field twice on the form, once as a string and once as a file upload. I'll play around with that a bit, but in the meantime if you remove the second field then I think the form will work as you are expecting.

>> I have a client that no longer wants to store dates in his app. Instead, he wants to store the number of days from a reference date.
I strongly recommend you use Dec 28th, 1800 as the reference date. If you do this then there's effectivly nothing to do, just store the date as a LONG.
