Howdy!

My IW app is deployed as an ISAPI.dll and for some unknown reason, it quits responding after a lot of activity (not sure why).

Has any one implemented a way of monitoring the module to see if it is still running? And if not, how to restart it in ISAPI?

I guess I could write a service that does a rest call to the IW app every 15 to 30 seconds to see if it responds.

If I can't figure out how to restart it, I guess I could text message or e-mail an administrator.

Any how, open to ideas.

Happy New Year!

With a page reload the jquery grid/dbgrid loses the filter and sorting settings. 
How can that be prevented?

Is there a way to tell if a recipient has opened or even received the email I sent?   I've looked everywhere in idSMTP and idMSG.  I see that idMSG has a ReceiptRecipients property and idSMTP has an OnFailedRecipient, but I don't know how to make use of either of these.

Since IntraWeb 15.2.28, the design folder has removed from the source download.

Is that possible to add back design folder in source zip archive?

I have a TIWBSTabControl in a frame.

When this frame is created at runtime (with a TIWBSRegion as parent), the tabcontrol OnAsyncChange is not responding until the page is reloaded/refreshed.

If the parent TIWBSRegion.AsyncRefreshControl is called after frame create, the tabcontrol OnAsyncChange fires, but the same call makes TIWBSButtons in same frame unresponsive.

Workaround was to send a javascript which triggers a callback event, but could this be a TIWBSTabControl issue when created runtime within a frame?

Workaround script where "ajaxCallbackAction" is a custom js library function used to trigger callback events:
$("#'+fMyFrame.MyTabControl.HTMLName+'_tabs").off("shown.bs.tab").on("shown.bs.tab", function(e){ajaxCallbackAction("mytabchange",$(e.target).attr("tabindex"));});

Hi,

I am transferring byte arrays from .Net to Delphi. This operation is repeated thousands of times and the length of the byte array is beteeen 5k and 500k. The operations runs without issues for a couple of minutes but then crashes on the .Net side with the following error:

System.OverflowException
  HResult=0x80131516
  Message=Arithmetic operation resulted in an overflow.
  Source=Atozed.CrossTalk.Right
  StackTrace:
  at Atozed.CrossTalk.Right.CTStreamReader.Read() in Atozed.CrossTalk.Right\CTStreamReader.cs:line 67

  This exception was originally thrown at this call stack:
    Atozed.CrossTalk.Right.CTStreamReader.Read() in CTStreamReader.cs


On the Delphi side I am using ByteArray.AsDelphiArray to get the bytes. The exception is happening when this method is called.

If I take the same byte array which causes this and transfer it in isolation (e.g. without making any other transfers beforehand) then everything works fine. So the error is caused by repeating the operation many times with different arrays.
 
I have already tried to use CopyToDelphiArray instead but it yields the same error.
 
I have also added a logic which catches this error and reverts to use a for loop to get the bytes from the ByteArray by index. This works but unacceptable slow. Note that once the exception was thrown AsDelphiArray only works for a couple of calls and then the same exception is thrown.

Hello, will it be possible to have an IWLink and an IWURL with CDN icons in the FontAwesome style?. Something similar to what was done with IWButton in its Image.WebFontClass property. In advance thanks for the help

Hi folks,

there is a new big update available for IW 15, version 15.2.49:

https://www.atozed.com/2021/12/intraweb-15-2-49/

Tons of exciting new stuff:

After several requests to extend our initial idea of creating an easy to use generic storage area (named TIWClipboard), the class has been completely refactored and greatly extended.

Also, we have greatly extended the TIWjQGrid and TIWjQDBGrid. Filter toolbar, DatePicker, Lookup columns and more.

Check it out: https://www.atozed.com/2021/12/15-2-49-h/

Enjoy! 

Hi,

I understand that if I create a .net object from Delphi then CrossTalk on the .net side will keep a reference to it until I call free to avoid it being collected by the Garbage Collector.

What happens if the .net object is created and returned by a .net method? Will CrossTalk keep a reference to it until I call free? If so does that means that whenever an object is returned I must call free on it on the Delphi side?

Hi,
I am trying to use a netstandard2.0 assembly from delphi. From the generated unit's uses list NET.mscorlib is misssing. I have added it manually and then the unit works. But I am wondering how well using a netstandard2.0 assembly will work and will I run into other issues.
Seems like using a netstandard2.0 library is not tested before CrossTalk is released which makes me worry.
