Hi,

Scenario:

In a project I am working on, we use hardware devices running a webbrowser as a display but no touchscreen, mouse or keyboard attached.
They are configured to load a webpage https://webserver.local/externaldisplay
The page https://webserver.local/externaldisplay is handled by a TContentForm in a IntraWeb application.
That page contains a TIWMonitor to poll the server and act based on the response.
When there is a network error or the server is stopped, the client should display a message informing the user of the device.
When the server is restarted the communication has to be restored. No user intervention should be necessary.

Part of this is working.

* After starting up the device, a session is created and the page is loaded via the content handler
* The page is refreshed based on the TIWMonitor response
* When I close the server, a message is displayed in the browser
  TIWMonitor.jsCallbackName gets called with value as a parameter. value == -1 when the server is gone.

But when I restart the server, the value keeps being -1. Reason is the old session does not exists anymore.
What should I do to create a new session on a $/QueryStatus call?
Or in what other way can I get the client to keep working after a server restart?

I have to check the IP from the client before allowing access to a page.
I test this in TContentForm.OnBeforeExecute and would like to return 403 Forbidden

Result is the exception 'Reply type already set.'

Delphi component tcombobox has a property "droppeddown" which  
indicates whether the drop-down list is currently displayed.
Does Intraweb have a corresponding property?

Hi,

Last time I used TIWMonitor was with IW15.2. 69. The behaviour back then was that TIWMonitor.OnAsyncEvent would be called when WebApplication.Status.Value == TIWMonitor.TargetValue. Now in IW15.3.12 it is called on every TIWMonitor.Interval. See it by running demo IWMonitor2.

BUT Demo IWMonitorProgress is working correct...

It seems to go wrong when no ProgressIndicator is used and using TargetComparison = tcEqual like in demo IWMonitor2.
Changing IWMonitor2 demo so TargetComparison = tcEqualOrGreater then it works again.

Update JR20230901:

It's in the IW Javascript library _isTarget(aValue)

Hello!

I'm creating a very complex webpage in Intraweb 15.3.10. It creates houndreds of images och positions them on absolute positions on the web page. All this is mixed with a lot of component that are created runtime. 

My problem is the response is very unreliable. On a very fast computer it sometimes manages to display a proper webpage, but mostly it fails. Colours are wrong, components are missing, events on components dos not fire among other things. The result may vary depending on webbrowser and computer speed on client.

When checking the log I can see that the when the rendering is completed in the WebServer the client keeps on doing small updates on the screen for a long time.

When resizing the webpage i update the positions and sizes on all components to match the new webpage size, this operation often fails too. Positions are changed but does not get updated on screen for example.

Is there some "max limit" of the complexity that a webpage can handle? Can this be increased?

Best regards, Mikael

Hello!

Just came back from my holiday and updated Intraweb from 15.3.7 to 15.3.12 and now the IWAppFormAsyncResize event is not called anymore!?
The IWAppFormResize is still called.

Any ideas?

Best regards, Mikael

Hi guys,

here's a maintenance update for IW 15, version 15.3.12 with some important fixes and especially a more solid WinHttpClient layer which is used for requests that IntraWeb applications make when communicating with external services, such as Google/Azure/Facebook server (OAuth authentication), Google API (ReCaptcha), IP Geolocation services (IWIPGeolocation classes) Telegram and Discord (notification via IWTelegram and IWDiscord), etc.

Enjoy! 

I just installed the demo version for Delphi 11. Every demo project on GitHub throws errors about missing assemblies, some on drives/paths that are obviously from the development/build system, such as Assembly not found: D:\Source\CrossTalk\Source\CrossTalkWPF\bin\Debug\CrossTalkWPF.dll

I figured out how to add an assembly to a test project. Outside of that, I do not know how to get started using CrossTalk. I have an important project that I would prefer to build in Delphi. But I can't do that, let alone make a decision about purchasing CrossTalk, if no information is provided on how to use it.

Hi all,

Here is a small guide on how to create a Discord channel to receive notifications from your IntraWeb applications via IWServerMonitor.

First of all, you must register a Discord account. The process is simple and straightforward. You just need to chose a display name/user name and use your email: https://discord.com/register

After creating your user, you will receive an activating email. After that you can start using your account.

Here's how you create a new server/channel that can receive notifications from your server:

Create a Discord Server:

If you don't have a server yet, you'll need to create one. If you already have a server, you can skip this step. To create a server:

• Click the "+" icon on the left sidebar of Discord.
  
• Choose "Create a Server."
  
• Follow the prompts to set up your server, giving it a name, selecting a region, and choosing an icon.
  

• Right-click the server's name in the left sidebar.
  
• Select "Create Channel."
  
• Choose "Text Channel."
  
• Give your channel a name and customize its settings as needed.
  

• Go to the text channel you created.
  
• Click on the gear icon to the right of the channel name to access channel settings.
  
• In the settings, select "Integrations."
  
• Click the "Create Webhook" button.
  
• Give your webhook a name and optionally choose an avatar for it.
