构造微小的EXE程序

构造微小的EXE程序

本文参考了网上的帖子《VC++下编译极小的程序》,《VC8中打造512字节超小应用程序》。废话不用说，直接上两个例子：

例子一: 一个Console程序

    1 #include <windows.h>

    2 

    3 #pragma comment(lib, "User32")

    4 #pragma comment(lib, "Kernel32")

    5 #pragma comment(linker, "/Entry:main")

    6 #pragma comment(linker, "/Merge:.rdata=.text")

    7 

    8 bool WINAPI StdOut( LPCTSTR lpString)

    9 {

   10     HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);

   11     DWORD numOfCharsWritten=0;

   12     return WriteConsole(hStdOut, lpString, lstrlen(lpString), &numOfCharsWritten, NULL);

   13 }

   14 

   15 int main()

   16 {

   17     TCHAR *pChar = TEXT("Hello World!\n");

   18     StdOut(pChar);

   19 }

采用VC9命令行编译 cl minic.cpp /link /align:16，编译后大小为768 byte。


例子二： 一个窗口程序

    1 #include <windows.h>

    2 

    3 #pragma comment (lib,"user32.lib")

    4 #pragma comment (lib,"kernel32.lib")

    5 #pragma comment(linker, "/Entry:main")

    6 #pragma comment(linker, "/Merge:.rdata=.text")

    7 #pragma comment(linker, "/Subsystem:windows")

    8 

    9 void *operator new[](unsigned int size){

   10     return HeapAlloc (GetProcessHeap(), NULL, size);

   11 }

   12 

   13 void operator delete[] (void* memblock){

   14     HeapFree (GetProcessHeap(), NULL, memblock);

   15 }

   16 

   17 void main ()

   18 {

   19     TCHAR* str = new TCHAR[250];

   20     wsprintf (str, TEXT("The system has run %d\n"), GetTickCount());

   21     MessageBox (NULL,str,str,MB_ICONINFORMATION);

   22     delete[] str;

   23 }

采用VC9命令行编译 cl msgbox.cpp /link /align:16，编译后大小为944 byte。
