Hello everyone.

I use iw 15.5.9 and changed my grids to IWjQDBGrid but, i cant syncronize the selected row with my firedac memtable. I cant navegate like iwDBGrid. On iwDBGrid, i used the event onclick on the collumn to move my dataset with locate but i dont know how to do that with IWjQDBGrid.

I need that because i show some info and made some updates.

anyone can help me to syncronize firedac memTable with IWjQDBGrid ?

Hello, 

We're experiencing some strange behaviour with the sessions on one of our clients. The program runs on an IIS and it's an ISAPI application connected to a database that basically manages the lawyer's files with some menus and forms that interact. 

The client wants that the session they are working in will never expires until they don' close the window browser, and this can be hours with the browser opened but without user's interaction. To do so, we have setted all forms with the keep-alive true and lengthened the servercontroller sessiontimeout to 240 minutes.  

If perhaps the applicaton remains an hour and the user comes back to the form and clicks on it, sometimes the application returns to the main page and starts another session instead of remaining to the form with same data they've leaved an hour ago, without errors and without closing the session.  

If we look at the server we suspect that the previous session is still running, but impossible to reach, and surely a new session has been created. 

I've recently changed sessioncookies to false but it's the same and i think usecookies it's mandatory as we work with sessions.

What else can we review? 

Thank you very much.

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);

Does anyone know what this error means.

Hello,

I want to add a image to a TIWGradButton, in front of 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
