A bit of background. I have, at a client's site, approx. 6 - 8 Intraweb SA servers running on a virtual Windows 2018 server (using http.sys and running on port 80). I have limited control over what the hosting crowd decide in terms of virus / malware / windows patch update timetables etc. The reason that multiple servers run on one VM is essentially related to costs to the client. Some of the Intraweb servers have 1,000 clients, others have 50! The reason they are SA (instead of a service) is simply to do with ease of monitoring them! Eventually I will develop a "monitoring app" that will tell if a server has stopped etc.

To the issues (and this is more a query if anyone else has struck these):

1) If one of the SA servers is down and a client tries to login they don't get an error. The simply get the login screen for one of the other SAs that is running. Which confuses the client! Is there a way of having a "default" SA server ... like a 404 page!

2) Shutting down one of these SA servers causes Windows Explorer to "lock up"! This is a bit difficult to explain ... but if you close the server and there is then no desktop response. I'm on a remote connection so I know that Windows hasn't locked ... I can still do file transfers etc. If you wait long enough (15 - 30 minutes) Windows does come back (sometimes with the "Explorer has stopped responding message") and you can recover, without a reboot etc. Of course I never have such an issue on my development computer. This may be related to running them as "application" as opposed to services.


Anyway just seeing if anyone else has had such issues.

We have released a new user kit version. Download it here: https://github.com/CosmosOS/Cosmos/relea...t_20190508

This release includes the following:

• Support for VS2019
  
• CGS and Fat fixes
  
• Added arithmetic overflow checks
  

I recently took over development/maintenance on a project written in Builder C++ 6 and just converted to Indy 10.   Some quirky unexpected problems occurred that seem to be related to the error handling.  I am pretty much a novice when it comes to Indy so I'm struggling to figure it all out.

Web searches found several comments by RLebeau that said "let the server handle the exceptions".   I looked, but never found, for code samples that would clarify what he meant. 

In this case TIdTcpServer Execute calls DoPassthruServerExecute, which calls HandleFirstCallerMessage, both of which have try ... catch sections.  There is also a TIdTcpClient and a ReceiveThread (TThread, TIdContext which is passed the server context) that has a try .. catch block, and which catches EIdConnClosedGracefully.

I've attached a stripped down code that has all the essential code and error handling.  I would greatly appreciate it if someone could take a look at it and let me know if they see any obvious problems or design issues.

Thanks.

Hi,
When I use the next code with ModalWindow to download a pdf I am getting the next message in chrome console.
The PDF is downloaded but I get the warning.
Is there a way to avoid it?

Howdy All!

I have a few places where I am using the 'stock' IW buttons where I need events that are NOT asynchronous.

In all my uses of TIWBSButtons, I use the RawText property that allows me to format my buttons caption as needed.

With the default TIWButton, it sets the caption as a Value attribute.

Without modifying the IW source code, how can I set the TIWButton caption using RawText like I do with TIWBSButton?

Thanks in advance,

Shane

Howdy All!

I am putting the final touches on my new web responsive web app and I am running into several problems with IWLocker:

1) If the current page has been scrolled to where the top of the page is outside of the view port and the IWLocker gets called, it is NOT shown in the because it is being displayed based on the top of the page.

2) I need the ability to make the displayed image responsive. It really would be nice if the IWLocker allowed multiple size breaks.

I am guessing the IWLocker is a javascript function. Where is it so i can try to make the above changes or does anyone have an alternate solution that works in a similar fashion as the IWLocker.

** UPDATE** 

I woke up and decided the 'default IW' loading image would be fine if it fixed the above problem. I cleared my image and tried it.... if the current page is still scrolled beyond the top of the initial page, the same results.

THanks,

Shane

Hello,

I´m trying to write a Lightstreamer client using C++ Builder Tokyo and TIdHTTP component.
I wrote this code based on the python client demo. 
TIdHTTP is receiving data using a simple TStream descendant and I get these data on the Write method.

This is part of the connection thread, it creates the session and stay connected to receive data.

[color=rgba(0, 0, 0, 0.87)]Hi, I tried my Delphi Rio Update 1 (Delphi 10.3.1), but I am not able to install IW 14.2.10 after installing the IW paracede disabled in Install Packages and when enabled this error appears:[/color]
[color=rgba(0, 0, 0, 0.87)]
Can not load package C: \ Users \ ..... \ dclIntraweb_10_D10_3.bpl. The specified module could not be found.

Is the IW 14.2.10 version compatible with Delphi 10.3.1?
Thank you.[/color]

What is the ServerController: ComInitialization property and what does it do? 

Mine was set to ciNone but everything worked. There are 2 other options ciMultithreaded and ciNormal. Could someone please explain these setings 

Thanks

Hi,

I am having some problems compiling the latest Indy components for C++Builder XE7.

I am using Windows 10 Pro.

Rebuilding using Fullc_XE7.bat/Fullc_All.bat does not produce the required .bpl files for XE7.

For Rio everything (compilation/installation) worked fine.

There are two warnings that comes up while running the script, don't know if this might have side effects.

It also said that system cannot find : "C:\Users\Public\Documents\Embarcadero\Studio\15.0\Bpl\*Indy*.bpl"


The problem seems to be pointing there.. Ran the Fullc_XE7.bat script again but with the line deleting the files "del /Q *.*" removed. And then found the bpl files there, but could not install the components.
