Hi,

The following code snipsets i used before IW15.5.0.
See also: ajaxCall in dedicated web worker thread

But actually the response code will always be executed, even if i set:

UserSession()->WebApplication->Response->Code = 200;
aHandled = true;

Does anybody know how to change the C++ code according to the description in the version history ?

class TChatCallbackRef : public TCppInterfacedObject<TIWCallbackProc3>
{
public:
INTFOBJECT_IMPL_IUNKNOWN(TInterfacedObject);

void __fastcall Invoke(TStrings *aParams, UnicodeString &aResult, bool &aHandled)
{
// class method
TIWUM_Frm_ChatA::GetNextItem((TStringList*)aParams, aResult, aHandled);
}
};

RegisterCallBack(_D("GetNextItem"), _di_TIWCallbackProc3(new TChatCallbackRef()));


__classmethod void __fastcall GetNextItem(System::Classes::TStringList *ListParams,
  System::UnicodeString &ListResult,
  bool &aHandled);

Modified

Callback infrastructure was refactored due to incompatibilities with FreePascal/Lazarus.
A minor method signature change was necessary in 2 of the callback methods.
The aHandled parameter in TIWCallbackProc3 and TIWCallbackProc4 became “var” parameters instead of “out”.
In case your code uses one of them it is possible that a small adjustment will be necessary.
In that case just change the aHandled parameter from out to var and the application will compile and work as before:

TIWCallbackProc3 = reference to procedure (aParams: TStrings; out aResult: string; var aHandled: Boolean);

TIWCallbackProc4 = reference to procedure (aParams: TStrings; out aResult, aContentType: string; var aHandled: Boolean);

Hello,

I want to add a image to a TIWGradButton, in front of the Caption.

so that the Button then at runtime has a Image (<IMG SRC="myimage.png">) followed by the Caption.

Is this possible? If yes, then please provide code snippet, 

thank you in advance

Good morning,
due to the decision of Centralgest to give up the support for the Cgdevtools package for Intraweb we have to migrate all our projects from Cgdevtools to Intraweb last version.

We would like to know if someone is in the same situation as us, to help each other, and if there is any guide or some tool to simplify the migration.

With Best regards
Francesco Sgaravatti

Hi,

I use a TIWCalendar component in a frame that is displayed in a modal window.
Recently only the modal window is displayed but the calendar is no longer shown.
I can't say whether it stopped working before the current Intraweb version.

An example is in the appendix.


IntraWeb Application (Indy - x86)
Edition: IntraWeb Ultimate Edition
IntraWeb Version: 15.6.5
32-bit Server on 64-bit Windows
