c++builder

I have been updating code fomr an old legacy project build using C++ Builder 2010 to compile with C++ Builder 10 Seattle . I have mostly had to change paths, a lot of dupIgnore to TDuplicates::dupIgnore , reimport some components like MSXML and MSMQ etc. First for a bunch of subprojects that the main project uses in the form of bpl's and dll's and finally the code of the main project compiles. But... it fails a linking :P [ilink32 Error] Fatal: Unable to open file 'TYPES.OBJ' I have tried to find info about potential issues and many mention making sure System is supplied in the Unit Scope

The code below was written for Linux and uses open, read, write and close. I am working on a Windows computer where I normally use fopen, fgets, fputs, fclose. Right now I get a no prototype error for open, read, write and close. Is there a header file I can include to make this work on a Windows computer or do I need to convert the code? Can you show how to convert it so it works the same on Windows or at least point me to an online document which shows how to convert it? #include <stdio.h> #include <string.h> #include <stdlib.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h>

I inherited a Delphi application and I know nothing about object pascal. It's a BPL that I need to compile into the new version of C++ Builder XE . When I run a make I get the error: E2064 left side cannot be assigned to. I've learned enough obj pascal to know I have a constant that is trying to be assigned a value. But, apparently, you can over ride this behanvior; essentially turning constants into vars by going into Build options under the Delphi compiler and turning on "Assignable Typed constants". I did that and I continue to get the same error. I tried surrounding my code with {$J+} and

I am trying to pack some structs with Borland C++Builder (XE6) (in the future: bcc). I am using a library which uses the following construct to create structs: #ifdef _MSC_VER #define PACKED_BEGIN __pragma(pack(push, 1)) #define PACKED #define PACKED_END __pragma(pack(pop)) #elif defined(__GNUC__) #define PACKED_BEGIN #define PACKED __attribute__((__packed__)) #define PACKED_END #endif PACKED_BEGIN struct PACKED { short someSampleShort; char sampleByte; int sampleInteger; } structType_t; PACKED_END The bcc compiler does not like the MSC __pragma , and does not like preprocessor directives

I have made a C++ Builder XE form with rounded corner with the help of the following code BorderStyle = bsNone; void __fastcall TForm1::FormCreate(TObject *Sender) { HRGN frmrgn; frmrgn = CreateRoundRectRgn (0, 0, ClientWidth, ClientHeight,12,12); SetWindowRgn(Handle,frmrgn,true); } It looks cool but the border is missing, I tried many thing but not get good result so please help me to draw border of color RGB(96,96,96) And I want to make whole form dragable. 1. Painting a dark grey border This one's easy, depending on how complex you want the border to look. If you just want an outline in
