I am using C++ Builder and am creating a VCL Forms application.
Here is my code:
std::string returnStringFromUnicodeString(AnsiString str)
{
std::string s(str.c_str());
return s;
}
Currently I have this in the main.cpp file and can use this function from any other functions in this .cpp file.
My question is this: How can I call this function from another GUI form? I have included the .h of the main .cpp file but still have no luck.
Do I have to make it public or some other method?
Thanks
You need to declare your function in a header, and you need to place the implementain in another cpp file, not ine with a main in it, so no int main or void main etc
You probably want to put that helper function in separate header and cpp files, so that you can use it across your project.
You need to add:
std::string returnStringFromUnicodeString(AnsiString str);
to your main.h file.
A different way, is to add a prototype with extern in the form you want to use it:
extern std::string returnStringFromUnicodeString(AnsiString str);
But I think is better to use headers.
AnsiString?
