When building an Intraweb app as Windows service, the Name used is from TIWServerController.AppName. This name can't use spaces. 
A customer would like to have the service named like 'CompanyName ApplicationName'.
TIWServerController.DisplayName can be used for this.

Isn't it possible to use this DisplayName for the name of the Windows Service?
I understand that this could be a breaking change for existing applications.

(Sorry for possible duplicate post. I can't find the original one in forum... )
Hello,

I use an application model like the "AsyncRenderFrame" demo.
Only one frame is active, the previous is detroyed.

Where do I save the previous frame state if I need to reopen it?
I mean: checkboxes, radios, edits, dataset cursors, etc.

Now I use the "session.clipboard" system as a memory kv store for this purpose, but I am not sure if it is a good choice.

Thanks,
Eddy

Hi,

I noticed that TIWEdit's OnAsyncKeyUp event fires twice when I enter the first character!

Hi guys,

new update with some important security update/feature

https://www.atozed.com/2022/04/intraweb-15-2-53/

Enjoy 

Hi,

As a result of an exception the user was shown the exception page including call stack details. This while TIWServerController.SecurityOptions.ShowSecurityErrorDetails = False. 
I would like to show the user the error message but without these details. On the server this error, including the details should stay.

A second issue with the attached testcase shows a small memory leak after the exception is generated.

Using IW 15.2.52

Hi,
I am in the process of creating a push notification service where the clients will be connected all the time to the http server providing the service. I am creating the server and client apps, but I need to detect when the connection is lost on the client side via something similar to a windows hook. I don't want to create a TTimer or a thread to keep checking the connection. I want something more smarter that mimic the same thing on cell phones (Android/iOS).

I want the client to know when the connection was lost and when it was restored so it can reconnect to the service again automatically. 

Knowing that the PCs that will run this will be inside a domain so some users will be allowed access to the internet, some won't. So I can't do something like keep pinging "google.com" or any other website because it will not work for some users. 

This has to be done using Indy components only because I want the app to support other OS(s) as well when the C++ Builder supports Linux for example. So it has to be as cross platform as possible.

For example, I want the program to detect if I removed the Ethernet cable or turned off the WiFi on the laptop, and when I reconnect the Ethernet cable or turn WiFi on it should detect that too.

I remember there was a talk about this or something similar somewhere but I can't find it again. Anyway

Thanks in advance,
Ahmed Sayed

Hi @all,

is there an example how to use

- the pattern-property (e.g. a regular expression)

- the regionalsettings-property (e.g. change decimal-point / thousand-separator)

in TIWEdit?

The samples on github are nice but don't use these properties.

By the way:

What is the placeholder-attribute for? As I understand it, there should also be a corresponding property placeholder-text.

Thanks in advance for hints!

Hi guys,

there is a new IntraWeb 15 update here:

https://www.atozed.com/2022/04/intraweb-15-2-52/

Enjoy! 

Good afternoon colleagues! 
There is a task to connect to the HTTP server using SSL and certificates. When checking the validity of certificates with OpenSSL commands, the result is successful, and the response shows that TLS1_2 is used. When trying to connect to the server via IE, the result is successful. The server response is there. However, when trying to connect from the program using the IdHTTP and IdSSLIOHandlerSocketOpenSSL components, the connection is not established. Mistake:

Error Connecting with SSL.
error:1409442E:SSL routines:SSL3_READ_BYTES:tlsv1 alert protocol version. 

Indy version 10.6.1.5182 OpenSSL version "1.1.0j" 20 nov 2018 .

Please tell me what could be the reason? Maybe need to install a more recent version of Indy?

Dear All; when using the TIdHTTP and TIdCookieManager components, how do I accept a cookie?

Here's what I'm trying to:
