问题 I'm using Inno Setup (Unicode) with a set of DLL's that I'm writing in Delphi XE2. The DLL's have VCL forms which are shown during the installation wizard/progress. I've tried out implementing VCL Styles in my Inno Setup installer. All is well, except for the forms which are created within these DLL's. Some of the form is skinned, but not all of it...

问题 Consider the following code snippet (in Delphi XE2): function PrepData(StrVal: string; Base64Val: AnsiString): OleVariant; begin Result := VarArrayCreate([0, 1], varVariant); Result[0] := StrVal; Result[1] := Base64Val; end; Base64Val is a binary value encoded as Base64 (so no null bytes). The ( OleVariant ) Result is automatically marshalled and sent between a client app and a DataSnap server. When I capture the traffic with Wireshark, I see that both StrVal and Base64Val are transferred as

问题 I would like to clean concrete classes from interface section, but the compiler doesn't allow to make it. Whether there is an opportunity to make so that the external code couldn't address to concrete classes? unit Unit2; interface uses System.SysUtils , System.Generics.Collections , System.Win.Registry ; type IMyRegistry<T> = interface procedure WriteValue(const Key, Ident: string; const AValue: T); function ReadValue(const Key, Ident: string; const ADefVal: T): T; end; TMyRegistry<T> =

While compiling a runtime package the following error occurs: ComponentsR.vrc(61): error RC2135: file not found: ComponentsR_Icon4.ico There are no icons or resources in this runtime package, so I don't know what to do with this message.
