The problem is you can’t template a typedef, also there is no need to typedef structs in C++. The following will do what you need
According to CodeGuru: CString to std::string: BUT: std::string cannot always construct from a LPCTSTR. i.e. the code will fail for UNICODE builds. As std::string can construct only from LPSTR / LPCSTR, a programmer who uses VC++ 7.x or better can utilize conversion classes such as CT2CA as an intermediary. std::string to CString: (From Visual Studio’s … Read more
This is not an error, it is a warning from your Microsoft compiler. Select your project and click “Properties” in the context menu. In the dialog, chose Configuration Properties -> C/C++ -> Preprocessor In the field PreprocessorDefinitions add ;_CRT_SECURE_NO_WARNINGS to turn those warnings off.
Since your compilation fails with out of memory, there’s probably not enough memory to compile your program. This can’t possibly be because of ‘a session management problem’ as suggested in the accepted answer. Is mysql eating more than it should? Is 300MB enough to compile C++ anyway? Serving JSon (like for a REST interface) in … Read more
For that you need reflection in C/C++, which doesn’t exist. You need to have some meta data describing the structure of your classes (members, inherited base classes). For the moment C/C++ compilers don’t automatically provide that information in built binaries. I had the same idea in mind, and I used GCC XML project to get … Read more
The mysql.h file from the libmysqlclient-dev Ubuntu package is located at /usr/include/mysql/mysql.h. This is not a standard search path for compilers, however /usr/include is. You’d typically use the mysql.h header in your code like this: If you don’t want to specify the directory offset in your source, you can pass the -I flag to gcc … Read more

I want to evaluate a string with a switch but when I read the string entered by the user throws me the following error. error: invalid cast from type ‘std::string {aka std::basic_string}’ to type ‘int
In C99 the available basic integer types (the ones without _t) were deemed insufficient, because their actual sizes may vary across different systems. So, the C99 standard includes definitions of several new integer types to enhance the portability of programs. The new types are especially useful in embedded environments. All of the new types are … Read more
