Language Basics Weekly Delphi Lesson [Print Lesson] Week 35, Posted Monday 8/30/2010 Content changes every Monday @ 1AM!! Check back once per week. Learn! Review! Test Yourself! FAQ of the Week Question: Can I call a DotNet DLL from my Delphi Win32 application? For example, with Delphi 7 or Delphi 2010? Answer: It's not easy because the .NET RTL resides in a different process. You can wrap up the DotNet DLL into an ActiveX control and call it or have both your app and the DotNet DLL write to the registry, a file, etc. By the way, you CAN wrap up a Win32 DLL in a DotNet DLL and call it from DotNet. Tip of the Week Tip: Before adding many new entries to a TStringList, set its Sorted property to false. Add all your entries. Finally, set the Sorted property back to True (if desired). Sorting is expensive, in terms of macnine cycles. By leaving the Sorted property set to True, you force the TStingList to re-sort itself after each entry. This can significantly slow things down. This applies to TStrings, as well, and all components that have a TStrings property, like TListBox, etc. Code Snippet of the Week Application.ProcessMessages I always found the sleep command in ObjectPAL very useful. The following code does about the same thing in Delphi. It makes use of GetTickCount which is a Win32 API call that retrieves the number of milliseconds that have elapsed since the system was started, up to 49.7 days. procedure TUtils.Delay(MillisecondsDelay: Integer); var    FirstTickCount: LongInt; begin    FirstTickCount := GetTickCount;    repeat         Application.ProcessMessages;    until ((GetTickCount-FirstTickCount) >= Longint(MillisecondsDelay)); end; Definition of the Week Strict Visibility:  The Strict specifier tightens up the scope for private and protected. With Strict Private, members within a class are visible ONLY within the class declared and Strict Protected are visible only within the class declared and descendent classes. Without strict, private and protected members can also be seen by all classes declared in the same unit (friendly classes). The Strict specifier was introduced with Delphi for .Net preview in Delphi 7 in an update to the .Net compiler preview and with Win32 in Delphi 2005 to fully comply with the .NET CLS. Delphi's traditional private specifier maps to the CLR's assembly visibility and the protected specifier maps to the CLR's assembly or family visibility.
