Windows编程点滴2011.8~2013.6

kongkongzi — Tue, 25 Jun 2013 06:23:00 GMT

1. dump文件的生成：参考MiniDumper.h和MiniDumper.cpp。/Files/toMyself/MiniDumper.zip

2. Windows DLL、COM、EXE的发布：版本属性的更新、版本信息在日志中的打印，打印代码参考：

#pragma comment(lib, "version.lib")

char* fileName = "test.dll";
     DWORD handle = 0;
     DWORD size = GetFileVersionInfoSize(fileName, &handle);
     BYTE* versionInfo = new BYTE[size];
     if (GetFileVersionInfo(fileName, handle, size, versionInfo))
     {
          UINT                   len = 0;
          VS_FIXEDFILEINFO*   vsfi = NULL;
          VerQueryValue(versionInfo, "\\", (void**)&vsfi, &len);
          WORD aVersion[4];
          aVersion[0] = HIWORD(vsfi->dwFileVersionMS);
          aVersion[1] = LOWORD(vsfi->dwFileVersionMS);
          aVersion[2] = HIWORD(vsfi->dwFileVersionLS);
          aVersion[3] = LOWORD(vsfi->dwFileVersionLS);
          XINFO("test.dll version is %d.%d.%d.%d", aVersion[0], aVersion[1], aVersion[2], aVersion[3]);
     }
     delete[] versionInfo;

3. Windows上安装程序的创建工具：NSIS，示例脚本参考TestServer_microsoft.nsi。

4. Windows DLL的设计：一般包括四个全局函数：Init、Terminate、CreateObject、DestroyObject，和一个接口类：没有成员变量，成员函数都为纯虚函数。设计目标：动态加载这个DLL时，能够重复地、没有内存泄露地实现LoadLibrary->Init->CreateObject和DestroyObject->Terminate->FreeLibrary。

5. Windows多线程程序的设计：线程的封装，参考代码

6. Windows ActiveX的设计：

7. Windows COM的设计：连接点事件的实现

8. 为64bit的exe封装32bit的dll：

TestInterfaceCom.idl：

[

uuid(BC4127B7-9353-4E7F-B975-01846CA706A1),

version(1.0),

helpstring("TestInterfaceCom 1.0 Type Library" )

]

library TestInterfaceComLib

[

uuid(865D32D9-8A37-4EE5-B4AB-C805893FD312),

helpstring("TestInterfaceObj Class" )

]

coclass TestInterfaceObj

{

[ default] interface ITestInterfaceObj;

[ default, source ] dispinterface _ITestInterfaceObjEvents;

};

HKEY_CLASSES_ROOT\TypeLib\{BC4127B7-9353-4E7F-B975-01846CA706A1}

HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{865D32D9-8A37-4EE5-B4AB-C805893FD312}\LocalServer32

HKEY_CLASSES_ROOT\Wow6432Node\TypeLib\{BC4127B7-9353-4E7F-B975-01846CA706A1}

VC编译错误

kongkongzi — Sat, 11 Sep 2010 05:30:00 GMT

收集各种崩溃错误及其解决办法

一、
出错触发：
增加了一个第三方库（G3D)。
错误输出：
unresolved external symbol "__declspec(dllimport) public: __thiscall std::exception::exception(void)"
unresolved external symbol __imp__strncpy
unresolved external symbol __imp__memmove_s

解决办法：
Try ignoring msvcrt.lib and linking in libcmt.lib?
I finally got my /MD to run against the problem that I had.
I removed 'msvcrt.lib' from my Ignore Specific Library list (under the release options).
Have you set your debug build to use multi threaded debug dll?
ignoring: libcmtd.lib msvcprtd.lib

LNK2005: <...> already defined in LIBCD.lib(osfinfo.obj)
Your libraries are mismatched: singlethreaded/multithreaded/multithreaded dll.
Check your compiler options to make sure you are using 'Multithreaded Debug DLL' (or /MDd) for debug builds
and 'Multithreaded DLL' (or /MD) for release builds. (MSVC: in project settings under C++ > Code Generation).

G3D里有下面的定义，注释掉就可以了。

#ifdef _DEBUG
    #pragma comment (linker, "/NODEFAULTLIB:libc.lib")
    #pragma comment (linker, "/NODEFAULTLIB:libcmt.lib")
    #pragma comment (linker, "/NODEFAULTLIB:msvcrt.lib")
    #pragma comment (linker, "/NODEFAULTLIB:libcd.lib")
    #pragma comment (linker, "/NODEFAULTLIB:msvcrtd.lib")
#else
    #pragma comment(linker, "/NODEFAULTLIB:LIBC.LIB")
    #pragma comment(linker, "/NODEFAULTLIB:msvcrt.lib")
    #pragma comment(linker, "/NODEFAULTLIB:libcd.lib")
    #pragma comment(linker, "/NODEFAULTLIB:libcmtd.lib")
    #pragma comment(linker, "/NODEFAULTLIB:msvcrtd.lib")
#endif

Windows编程细节

kongkongzi — Tue, 03 Aug 2010 02:44:00 GMT

网络程序忘了链接ws2_32.lib，报了很多错误：
error LNK2001: unresolved external symbol __imp__WSAGetLastError@0
……

在缺省情况下，C编译器为每一个变量或是数据单元按其自然对界条件分配空间。一般地，可以通过下面的方法来改变缺省的对界条件：
· 使用伪指令#pragma pack (n)，C编译器将按照n个字节对齐。
· 使用伪指令#pragma pack ()，取消自定义字节对齐方式。
