Hi there,


To start off, I know nothing about SSL or TLS.  We have a couple of clients that have requested to add SSL to our Webserver app. The clients are providing access to documents for their customers and will have no control over browser usage.

I am using XE7, IW 14.2.12 and I am trying to run the StandAloneSSL demo.
Downloaded the OpenSSL dll's 1.02q and placed them in the folder with the freshly compiled StandAloneSSL.exe.

With all browsers I am getting the error, this test was with Firefox :

Error code: SSL_ERROR_UNSUPPORTED_VERSION
This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox. Enabling TLS 1.0 and TLS 1.1 might allow this connection to succeed.

TLS 1.0 and TLS 1.1 will be permanently disabled in a future release.


The question is what should I assign to the CipherList and or SSLVersions?

TIA,
Craig

Hi All,

I have a multiform application, created as a SA HTTP.SYS EXE-file, placed on a SQL server where it runs as a Service. The username to start the service has been granted Logon as Service, and the same user has been granted logon to the database. Thereby the program can access and manipulate data in the SQL database. All good.

My program is created with UniqueUrl = on. It seem to be working as all UserSession vars for each user seem to be ok and intact individually. All good as well.

The program uses ADOConnection and ADOQuery, or ADOStoredProc to access and manipulate data in the various tables in my database.

Now it turns out there is multiuser problem. When calling a select from the same table from 2 different users and program instances, it appears that User 1 receives the rows User 2 selected. I have a search form showing a number of records depending on individual search criteria, and it appears as if results are being mixed among the users.

Where the IW application itself appears to be multiuser (thread?) safe, the ADOconnection do not.

Is that a well know problem with a well known solution or is this news for everyone ?

As it is the same username performing the call (the Logon as Service username) could it simply be a SQL problem ?

I'm fishing a bit here as I don't really know what to do, so if anyone have any proposals I will be very grateful to hear them.

Regards
Soren

How to use IWDBGRid CurrentField property to access the content of the current cell.
For example if the current cell contains a text: IWDBGrid1->CurrentField->AsWideString generates an access violation error

Hi All,

I have a form with an IwImage onto which I have loaded a BMP image.

      JpegOptions.CompressionQuality = 90
      JpegOptions.Performance = jpBestSpeed
      JpegOptions.ProgressiveEncoding = False
      JpegOptions.Smoothing = True
    end


Thus the image is loaded into the form as a series of HEX values, and not an image on a hard drive location anymore.

So when I create the form, and get this error message, aborting the creation of the form:

Error reading BTN_SoegVejning2.Picture.Data: System Error. Code: 87. The Parameter is incorrect.

The error is shown as a pop-up box with a n OK button, and when clicking it, the program is returned to where the formcreation was called.

I would like to know what I can do to avoid that error.

As it is not a file on a drive, it is not a question about access rights, or false directory specifications, but only a question of reading the HEX values from the form, which is compiled into the exe file. So what is it ? and is there anything different I can do to avoid this problem ?

The program runs as a SA HTTP.SYS service on a Wondows 2016 Server.

Hi Guys,

After much developing, today it was finally time to have multi users testing the multiform application. A number of errors came up, mostly "Access Violation" but also many of them relating to IWButton1.picture.data:

Error reading IWButton1.Picture.Data: System Error.  Code: 87. The parameter is incorrect .
In the errorllog the last executed line is: System.Classes.HandleException (Line 11150, "System.Classes.pas" + 5) + $47

Access Violation errors shown was (last executed line from the errorlog):

AV: System.Classes.TList.Get (Line 4927, "System.Classes.pas" + 3) + $3
AV: Vcl.Graphics.DeselectBitmap$qqrp9HBITMAP__ (Line 7155, "Vcl.Graphics.pas" + 6) + $A
AV: IWContainer.TIWContainerImplementation.get_IWComponentsCount (Line 713, "IWContainer.pas" + 0) + $0
AV: System.@FillChar$qqrpvic (Line 12064, "System.pas" + 3) + $0

I have ServerController properties set as follows:
Cominitialization = ciMultiThreaded
Cookieoptions.UseCookies = true
Cookieoptions.SessionCookies = true
Sessionoptions.UniqueUrl = true
Showstartparams = true

Can anybody tell me what is wrong, and if possible explaining why it happens and what to do to try to resolve the problems, please.

Regards
Soren

Added after post: I forgot to mention that during development time, even with multiple session in tabs in the browser, I have not had ANY of the above errors. It is as if they are multiuser related in some way, but as I do not know, I am just guessing. And I have tested both on my development machine (using Cassini) and after uploading to server, running it as a SA HTTP.SYS service. Both locally and server based at the same time, and using both Edge ans IE11 at the same time.

Could it be access to the location on the server ? If it is looking for the wwwroot dir in the location of the exe-file, should the users have rights to access that directory ?

Hi,
I ask for advice on scalability as our project is growing very quickly. I would need to scale my application (it is compiled as isapi.dll) giving more servers for our website and then dividing the database and directing requests to the different servers. I read about the Octagate product to sort requests to various servers. What are the guidelines for doing this? Can anyone give me some explanation on this?
Thank you
Andrea

What can I do to use it?

Thannks in advance,

I need some help using THTTPServer under Delphi,

I am attempting to write a server that will handle some client based data forms.

I can receive the POST transaction through CommandGet, and can read the data fields passed in the RequestInfo.Params.Values data elements with no problem.

But I am totally at a loss on how to send back the new data field values to the client.

Any help would be appreciated.

I am using Rad Studio Tokyo 10.2.3 with Intraweb 14.2.7
After Intraweb re-installation all messages, message boxes and error messages, are in an Asian language: not sure if it is Chinese or Japanes. What can create that ?
Just to precise that I am using Windows 10 Enterprise en the language is English US.
On the attached alert message for example, the OK button is written in Chinese or Japanese.
Error log below are in the same language.
