![]() ![]() #define STR_CONV_BUF_SIZE 12000 // the largest string you may have to convert. Instead define the following two functions: UnicodeString.c_str() returns wchar_t* and AnsiString.c_str() still returns char*.ĭon’t bother replacing all occurrences of String with AnsiString as suggested elsewhere. If you are using the type String in your code it now maps to UnicodeString and no longer to AnsiString. It is more difficult if you are passing a variable as an argument. If the argument is a string constant all you have to do is place the letter L in front of it. VCL object properties that returned AnsiString now return UnicodeString (for example Label->Caption). Unicode conversions may be needed (Ansi character to Unicode conversion).Īll VCL functions that used to accept arguments of type char* (for example Application->MessageBox) now require wchar_t*.It’s a little more effort at first but it saves you a lot later on. Copy your files into a new folder, create a new project and add your source files to it. Don’t let C++ Builder 10 Seattle convert your older Builder project.Tips for migrating legacy C++ Builder to C++ Builder 10 Seattle There are also cases where older C++ Builder compilers used to allow temporaries to be constructed and used in a way which is not allowed by the C++ standard, these will now be flagged as errors at compile time. The newer C++ Builder adheres to the C++ Standard, so any modifications would generally have to do with ambiguities relating to Variants, TDateTime, Cardinal, and how conversions/casts occur between these types. ![]()
