C++ Builder 5 to Builder XE
I've C++ Builder 5 in my machine and my project's code is in Buidler 5. Builder 5 has become obsolete now. I want to upgrade to some latest version of C++ Builder. As of now C++Builder XE is available. Please let me know whether I can compile my code in Builder XE? What are compatibilty issues between Builder 5 and Builder XE? If they are not compatible then please let me know which cd/ dvd of C++ Builder I should buy?

XE2 is the latest. > Please let me know whether I can compile my code in Builder XE? In general, yes. But you have to make sure any third party packages/components you are using are upgraded to XE/XE2 first, that your code is not making any assumptions about pointer/integer byte sizes, that any strings that interact with the VCL are Unicode-ready, etc. There is a whole migration section on the Embarcadero website: http://www.embarcadero.com/rad-in-action/migration-upgrade-center. -- Remy Lebeau (TeamB)

I recently converted a project from C++ Builder 5.5 to C++ Builder XE. Here are the lessons I learned and tips I can share:
1) Don't let C++ Builder XE convert your Builder 5 project. Copy your files into a new folder, create a new project and add your source files to it. It's a little more effort at first but it saves you a lot of headache later on.
2) The biggest problem is the Ansi character to Unicode conversion. All VCL functions that used to accept arguments of type "char*" (for example "Application->MessageBox") now require "wchar_t*". VCL object properties that returned "AnsiString" now return "UnicodeString" (for example "Label->Caption"). If the argument is a string constant all you have to do is place the letter "L" in front of it. It is more difficult if you are passing a variable as an argument. If you are using the type "String" in your
code it now maps to "UnicodeString" and no longer to "AnsiString". "UnicodeString.c_str()" returns "wchar_t*" and "AnsiString.c_str()" still returns "char*". Don't bother replacing all occurrences of "String" with "AnsiString" as suggested elsewhere. Instead define the following two functions:
#define STR_CONV_BUF_SIZE 12000 // the largest string you may have to convert. depends on your project
wchar_t* __fastcall UnicodeOf(const char* c)
{
static wchar_t w[STR_CONV_BUF_SIZE];
memset(w,0,sizeof(w));
MultiByteToWideChar(CP_ACP, MB_PRECOMPOSED, c, strlen(c), w, STR_CONV_BUF_SIZE);
return(w);
}
char* __fastcall AnsiOf(wchar_t* w)
{
static char c[STR_CONV_BUF_SIZE];
memset(c, 0, sizeof(c));
WideCharToMultiByte(CP_ACP, WC_NO_BEST_FIT_CHARS, w, wcslen(w), c, STR_CONV_BUF_SIZE, NULL, NULL);
return(c);
}
and use them whereever one type is returned and the other type is required and vice versa. Careful: what makes these functions convenient to use, i.e. the static buffer, can also cause undesired behavior. Make sure "AnsiOf/UnicodeOf" is not called as an argument of a function that may itself call "AnsiOf/UnicodeOf", or that "AnsiOf/UnicodeOf" is not used for two or more arguments of the same function.
3) Compile your project and resolve type errors by inserting calls to "AnsiOf" or "UnicodeOf" as applicable. Continue until your project compiles without errors.
4) Search for all occurrences of "sprintf", "fwrite" etc. These functions accept any variable type for some of their arguments so the compiler may not complain. Manually check whether a call to AnsiOf needs to be inserted.
5) Optimize: Eliminate some redundant use of "AnsiOf" and "UnicodeOf". For example "fopen(AnsiOf(..." can easily be replaced by "_wfopen(..." Also "fnsplit(AnsiOf(..." can relatively easily be replaced by "_wfnsplit(..." You will have to define the other arguments as "wchar_t" as well, which doesn't cause too much of a ripple effect. Furthermore "sscanf(UnicodeOf(..." can be replaced by "swscanf(..." Consider converting some of your variables from "char" to "wchar_t" wherever it makes the most sense. If y
ou used string functions such as "strcpy" etc. all you have to do is replace "str" with "wcs" in most cases. If you used "strncpy(s1, s2, sizeof(s1)-1)" as a safe version of strcpy, replace it with "wcsncpy(s1, s2, sizeof(s1)/2-1)" because the size of an array of "wchar_t" is twice the characters it can hold.
6) Be prepared that some VCL components such as TColorGrid may not longer be available and you will have to find a workaround.
7) The compiler wil tell you that some functions or object properties have been deprecated. You will have to work around them as well.
Once I got a handle on it didn't take longer than a day to convert a project with about 60,000 lines of code. Hope this helps.

Or, you could just let the RTL handle conversions for you. You can assign an AnsiString to a UnicodeString and vice versa, and the RTL will convert as needed. > 4) Search for all occurrences of "sprintf", "fwrite" etc. These > functions accept any variable type for some of their arguments so the > compiler may not complain.

Convert to C++ Builder XE from C++ Builder 6 and 2007
Any information regarding the roadblocks of converting the code build in C++ Builder 6,2007 to C++ Builder XE? On 6/20/2012 8:20 AM, Girish Duddu wrote: > Any information regarding the roadblocks of converting the code build in C++ Builder 6,2007 to C++ Builder XE?

There are good white papers regarding making this transition on the Embarcadero EDN site. I found that most of the changes I had to make fell into two categories: 1) Places where I was using moving data from VCL properties to or from explicit AnsiString, but I could easily change to String, i.e. convert to Unicode. 2) Places where I had relied on the c_str() method to provide a "C" string. If I really needed a "C" string, I would explicitly use AnsiString. It's a good idea to minimize these instances.

BUG (or issue) with Indy, C++ Builder 2010 and C++ Builder XE [Edit]
To reproduce this issue you need a clean installation (from scratch, no additional components installed, no Indy update) of C++ Builder 2010 or XE. It uses Indy 10.5.5 (with 2010) or 10.5.7 (with XE). Note: although it uses Indy to reproduce the issue, the version of Indy and Indy itself is not the one that causes this problem but the linking of C++ binary probably. Steps to reproduce: 1. Create a simple text file with the following content. Save it as "file.txt" or any other name. It can be also full email message but the text below is enough. {code} Subject: =?windows-125...

Problem with installing a Delphi component in C++ Builder XE
Hi everyone, I hope this is the right forum... I'm trying to install a delphi component (I only have the .pas sources) in C++ Builder XE. I went through the normal procedure (Components->Install a component; select the .pas files + Install in a new package; Package C++ Builder). I get a new project "namePackage.bpl" and I right-click on "Install". The compilation is succesful and I have a message saying that the new components have been installed and if I create a new project to use them, they are indeed available. The problem arrives when I try to compile this project since the .lib for the new package is missing. And I cannot add the path to the library since it was not generated as far as can see. No .lib and no .bpi. When I installed the package, only the .bpl was generated. I tried to change the Delphi compiler options on the package project to "Generate all C++ Builder files (including package libraries)" with no luck. I'm at lost here, is there an option missing here? What confuses me the most is that everything seems to work just fine during compilation. I only have two transtyping warnings on compilation and a "duplicate ressource" warning during linking. Thanks in advance for any advice you could give me.

C++Builder 2010: same old bugs.... goodbye, C++Builder.
I've tried the demo version, built my OCX, set the constrained size, and added some event handler. It works exactly like the old Borland CBuilder 6: the grab handles does not follow the constrained size, the OnCloseQuery and OnDestroy events are not fired, there's is not an OnAmbientChange event available. Building OCX is an important feature for us, as our customer needs them... so, if i were the one that take the final decision, i'll migrate to MS developement tools.... i'm not that one, but i'll strongly push in that direction. It's a shame, anyway. If you are courious about these bugs, then build an ActiveX library, an ActiveForm, and add to that form event handlers until you get this code: {code:cpp} void __fastcall TProva_OCX_2010::ActiveFormCreate(TObject *Sender) { this->OnCloseQuery = EventoCloseQuery; OutputDebugString("OnCreate"); } //--------------------------------------------------------------------------- void __fastcall TProva_OCX_2010::ActiveFormDestroy(TObject *Sender) { OutputDebugString("OnDestroy"); } //--------------------------------------------------------------------------- void __fastcall TProva_OCX_2010::EventoCloseQuery(TObject* Sender, bool &CanClose) { OutputDebugString("OnCloseQuery"); } //--------------------------------------------------------------------------- {code} Also set the constrained dimension for the ActiveForm, compile and place the OCX ...

The compilation is succesful and I have a message saying that the new components have been installed and if I create a new project to use them, they are indeed available. The problem arrives when I try to compile this project since the .lib for the new package is missing. And I cannot add the path to the library since it was not generated as far as can see. No .lib and no .bpi. When I installed the package, only the .bpl was generated. I tried to change the Delphi compiler options on the package project to "Generate all C++ Builder files (including package libraries)" with no luck. I'm at lost here, is there an option missing here? What confuses me the most is that everything seems to work just fine during compilation. I only have two transtyping warnings on compilation and a "duplicate ressource" warning during linking. Thanks in advance for any advice you could give me.

C++Builder 2010: same old bugs.... goodbye, C++Builder.
I've tried the demo version, built my OCX, set the constrained size, and added some event handler. It works exactly like the old Borland CBuilder 6: the grab handles does not follow the constrained size, the OnCloseQuery and OnDestroy events are not fired, there's is not an OnAmbientChange event available. Building OCX is an important feature for us, as our customer needs them... so, if i were the one that take the final decision, i'll migrate to MS developement tools.... i'm not that one, but i'll strongly push in that direction. It's a shame, anyway. If you are courious about these bugs, then build an ActiveX library, an ActiveForm, and add to that form event handlers until you get this code: {code:cpp} void __fastcall TProva_OCX_2010::ActiveFormCreate(TObject *Sender) { this->OnCloseQuery = EventoCloseQuery; OutputDebugString("OnCreate"); } //--------------------------------------------------------------------------- void __fastcall TProva_OCX_2010::ActiveFormDestroy(TObject *Sender) { OutputDebugString("OnDestroy"); } //--------------------------------------------------------------------------- void __fastcall TProva_OCX_2010::EventoCloseQuery(TObject* Sender, bool &CanClose) { OutputDebugString("OnCloseQuery"); } //--------------------------------------------------------------------------- {code} Also set the constrained dimension for the ActiveForm, compile and place the OCX ...
Upgrading Code from C++ Builder 4 to C++ Builder 2007
I am working on project written in C++ Builder 4, it uses TMS Component pack. Now the TMS Component pack has been upgraded so i do not find any compatible version of TMS Component to use with C++ Builder 4. I need to upgrade my code from C++ Builder 4 to C++ Builder 2007. I want to know whether code written in C++ Builder 4 is feasible with C++ Builder 2007. Thanks Arshdeep wrote: > I want to know whether code written in C++ Builder 4 is feasible > with C++ Builder 2007.

problem of converting from C++ Builder 6 to C++ Builder 2007
Hi, A program which was developed by our partner was built fine with C++ Builder 6. Now I need to make some changes to it. We bought C++ Builder 2007 a few weeks ago. When I open the program with C++ Builder 2007, I was told that the project needs to be converted. I agreed. Then when I compile it, some errors happen: [BCC32 Error] ComCtrls.hpp(435): E2272 Identifier expected [BCC32 Error] ComCtrls.hpp(3880): E2272 Identifier expected [BCC32 Error] ComCtrls.hpp(4658): E2272 Identifier expected ...... Anybody has any idea how to fix it? Thanks, Allen In article <14040@f...

Naming new console project
When I attempt to create a new console project using project|"Add new project" there doesn't appear to be any way to actually specify the project name.

All I want to do is to create multiple projects with names of my choice. Could someone please point me to suitable help or explain what I'm not doing? TIA ...

Project compatible with Builder 3 and Builder XE
Hello there, I've got a problem with a fairly old project based on Borland C++ Builder 3 which has to be ported into a Builder XE project, but still has to be used with the Builder 3 compiler now and then. Changing to the newer compiler wasn't that hard sofar, now the code has to be altered to fit the old compiler again. The main problem right now is that the Builder XE updates the dfm-files, causing Reading Form Errors in the old builder. I thought of having two sets of dfm files, one for the old and one for the new compiler. And then adding the matching form depending o...
Enum return value size mismatch in C++ Builder 5.5
Hi! I have been trying to do some maintenance on an old piece of software, written in C++ Builder 5.5 for Win32. I know this is old, but it relies on some external components and would probably be complicated to port to a newer environment. I have been trying to solve my problem by browsing through old posts using Google Groups, but so far have not been able to find anything. It uses several old DLLs, which when I got my hands on them were written for an even older version (Borland C++ 5.02). With the DLLs build with this version of the compiler, everything works fine. To avoid...
