Ntdll. dll): 0xc0000005: access violation problem:

 

 

A ------- it was found that the new operator was called during internal debugging.

I don't understand, in the DLL call new operator will have such a problem, search on the network, in the Microsoft msdn Forum (specific address: http://forums.msdn.microsoft.com/zh-CN/vclanguage/thread/951a04be-6b52-4617-b396-9c35e3755759/) to find related issues.

 

Then, according to the instructions, change the DLL generation method to "shared MFC mode"

Project properties-> General-> Project defaults-> Use of MFC

To set the properties "use MFC in a shared DLL"

In addition, I also found another article on the Internet, for console, solution: use C Runtime

Dynamic Link version of Library (set to ignore all default link libraries in your console project, and then link to msvcrt. Lib) (Address: http://www.poptool.net/software/p606/A60674501.shtml)

B ------ this problem occurs generally because the pointer is not initialized and other access violations occur. The error is described as follows:

Description: After the VC program adds the edit space (or other controls) and corresponding variables to the window (they are all added through the Class Wizard and are not considered a factor), compilation and connection can pass normally, however, 0xc0000005: Access

Violation error. After tracking and debugging, it is found that when the program runs in C ***** app: m_pmainwnd = in initinstance (),

An error occurs during the & DLG; statement.

Solution: Re-rebuilt all (re-build all) to re-compile.
