In carbide. c ++, select the "view process output" option to view the information output to the debug console. In addition, make sure that the value of the logtofile parameter in the EPOC. ini file is correct, that is: Logtofile 0 Logtodebugger

  The following is a dial-up section.Code(From the Nokia example), although there are not many codes, it is worth learning in many places, such as the use and cleaning of R classes, server/client mechanism, parameter transfer mechanism, and

Because the current carbide. c ++ 1.2 Express version does not have a wizard to automatically generate a cview derived class. So we created a project that accelerates development in the multi-view architecture.

The concept of a two-way circular linked list should be clearer than me. I will not talk about it here. I would like to summarize my two experiences in programming: First, if you just point out the direct precursor node when inserting it in the

Nokia recently released the new openc/C ++ plugin SDK (41.4 MB), supporting STL and boost. STL uses the famous stlport library. A person who previously provided the Symbian platform for porting and downloading packages has now become official

C ++ call conventions and naming conventions Call conventions:_ Cdecl _ fastcall and _ stdcall are call conventions (calling convention), which determine the following content: 1) the order of function parameters in the pressure stack; 2) the

1. Enter the if statement for bool, float, pointer variable comparison with "zero value. Tip: the "zero value" can be 0, 0. 0, false, or "Null Pointer ". For example, the IF statement for int Variable N and "zero value" is: If (n = 0) if (n! = 0)

1. programmers write code that they think has no bugs. 2. During software testing, 20 bugs were found. 3. the programmer modified 10 bugs and told the test group that the other 10 were not bugs. 4. the test group found that five of the changes were

Note the following when learning C ++. 1. Take C ++ as a new language learning (it has nothing to do with C! True .); 2. Read thinking in C ++ instead of C ++. 3. Read the C ++ programming language and inside the C ++ object Model, do not read them

Virtual function = virtual function Address Table = virtual table) Each class contains virtual function objects, and the compiler will specify a virtual table for them (actually a function pointer array), which is saved in the data area, it shares

Although template is very important, what is the relationship between it and "Using MFC? Yes! Chapter 2 when we design the scribble program, we need to use the collection classes of MFC, the template version has been available for this group of
