• Elliotte __invalid_parameter_noinfo is resolved by LIBCMT.LIB but not LIBCMTD.LIB

  Hi I'm having to define _SECURE_SCL=0 when compiling debug builds of my C++ applications which are built using the /MTd switch, otherwise the linker cannot resolve reference __invalid_parameter_noinfo. When the release build is generated using the /MT switch, there are no problems, since this reference is resolved by LIBCMT.LIB. I've used DUMPBIN to try to find __invalid_parameter_noinfo in all the standard installed libraries, but it ...Show All

• GarthK c/c++/c#

  I am currently an intermediate programmer in visual basic .net. I want to learn a C language and was wondering which I should learn first and the main differences between them. Between C, C++ and C#. Thanks, Korab C as a language has beeen around since the 70's. It is a very low level language (no classes as such) and while its popularity has been on the wane it is still the language of choice of developers who really want to get right d ...Show All

• Gregor Jovan Comparing ref pointers for equality

  Now that operator overloading allows to ref classes to be compared for equality using == syntax, how does one compare the actual ref pointers ( ^ ) for equality instead As an example: SomeRefObject ^ obj1(..initialized somehow); SomeRefObject ^ obj2(..initialized somehow); if (obj1 == obj2) // This compares the objects themselves for equality in C++/CLI I assume. How do I compare the ref pointers themselves ( ^ ) for eq ...Show All

• Henrik Dahl using WM_KEYDOWN to find which non system key was pressed.

  Hey all, I,m starting to learn MFC and I'm trying to write a program that will display which keys a user has pressed. I use WM_CHAR for normal keys and that works fine. I want to use WM_KEYDOWN for non-system keys that aren't supported by WM_CHAR. The problem I'm having is that I cannot display which key is being pressed when OnKeyDown() is called. Here is a sample of code that I unsuccessfully implemented: afx_msg void CMainEIWin::OnK ...Show All
