    Managed dll instead of an unmanaged one

    Thank you. Would using a managed C# DLL in unmanaged Delphi app cause any CLR issues ? Thanks
  2. 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

  4. 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
  5. 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.
  6. 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.
