Why did you declare you character buffer a size of 20? More than likely the sprintf placed more characters than that can fit in myChar. Instead, use safer constructs such as std::ostringstream or at the very least, declare you char arrays much bigger than you would expect (not the best way, but would at least … Read more
Inside your swap function, you are just changing the direction of pointers, i.e., change the objects the pointer points to (here, specifically it is the address of the objects p and q). the objects pointed by the pointer are not changed at all. You can use std::swap directly. Or code your swap function like the … Read more
I am using the following code for setting the time in a Date Control in MFC using C++ This will get the Date and set it to the control in what ever format the user machine uses. But I want to set it to a format of ONLY mm/dd/yyyy. There should be some way of … Read more
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 hope you can help me, cause I have no idea about what’s going on. I’m having the following error while trying to add Beecrypt library to my project: fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add ‘#include “stdafx.h”‘ to your source? Actually I did not … Read more
