I purchased "EurekaLog_7.11.0.1_Enterprise_for_RAD_Studio" with source code on January 21, 2021. The subscription ran out a year later. Since I purchased source code I decided to upgade EurekaLog so it would work with Rad Studio 12 Athens. To do this: I copied the Studio28 folder in the projects directory to Studio29. In the *.dpk and *.dproj files I replaced 28 with 29. In the "\Neos Eureka S.r.l\EurekaLog 7\Source\Common" directory I modified "ElDefines.inc" to add Delphi 12. With these changes "EurekaLogGroup.groupproj" successfully compiles and in the packages directory a new folder appears "Studio29". This folder is filled with the 290 bpl files and other files. When I try to install the packages I get the following message: "Can't load package E:\Installs\Studio29\EurekaLogExpert290.bpl. The specified module could not be found." The bpl's are there. What is the problem? Richard Maley

Access Violation when Enabling TTimer in TComponent
egnew posted a topic in RTL and Delphi Object Pascal
I have a component in a Delphi package. The component contains a TTimer. When I manually create an instance of the Component, everything works fine. But when I drop the component on my form, everything works until the component tries to activate the timer. When the component attempts to start the timer with "FTimer.Enabled := True;", the access violation occurs. The following code from Vcl.ExtCtrls is called with Value=True but as soon as "if Value <> FEnabled" executes, the access violation occurs. procedure TTimer.SetEnabled(Value: Boolean); begin if Value <> FEnabled then begin FEnabled := Value; UpdateTimer; end; end Is this a bug or am I overlooking something?
