Hi,

What's the equivalent of this code in C# ?

procedure FetchFromIStream( myStream : TStream ; myIStream : IStream ) ;
var
   TOS : TOLEStream ;
begin
   TOS:=TOLEStream.Create(myIStream) ;
   try
      TOS.position:=0 ;
      myStream.position:=0 ;
      myStream.copyFrom(TOS,TOS.Size) ;
      myStream.Position:=0 ;
      TOS.position:=0 ;
    finally
      FreeAndNil(TOS);
   End ;
end ;

TIA

Yes. But you need to use a tool like UnmanagedExports.

Thank you.
Would using a managed C# DLL in unmanaged Delphi app cause any CLR issues ? Thanks

Hi,

I have an application which loads & uses an unmanaged dll. All I have to do is drop the dll it in a specific folder.

Can I use a .Net  dll instead ? (I know the .Net dll needs to expose the same functions which are in the unmanaged dll)

Can an unmanaged & managed DLLs  be used interchangeably ?

Thanks

Hi,

Why do these two statemets give different results ?

Pos('#$02','bla,bla,#$02,bla');// Pos = 9 

const
  STX=#$02;

Pos(STX,'bla,bla,#$02,bla'); // Pos = 0

Thanks

Hello,
I am receiving data about different holidays in a delimited string e.g:
Booking number, flight details, package type, etc...

There are serveral holiday types e.g
Beach holidays
Ski holidays
All-inclusive
City breaks

Most of the holiday types have the same fields but there are some differences, e.g. some holidays don't have fight details.

I would like to create a function to which I pass the delimited string & it returns the object which represents the booked holiday:
Booking number, flight details, package type
Booking number, cruise details, package type, pick-up point

Which is the best to achieve this ?

I can create a record which holds all possible fields & return that as a result.  Is there a better way?

Thank you.

Hi,
I'm receiving data in this format:
[STX][0x1C][Field1][0x1C][Field2][0x1C][Field3][Field4][0x1C][ETX][LRC]
Which is the best way to read the fields between [STX] & [ETX] without using a loop?
Field1, Field2, Field3 & Field4 length are 2,6,3,5 respectively.

I'm using delphi & TComPort.
Thank you.

Hi,
Can anyone recommend a non-visual component for RS232 serial commnuncation ?
I'm working on a project which sends data over RS232.
I need to create requests & intercept responses.

Any RS232 components I can use or good examples I can browse ?
 
I'm using Delphi XE7.
My app is to run on Window platform.
Thank you
