windows API编程第二天2015.11.15

现在在公司加班，但是，不太喜欢现在这份工作，想去跳槽转去C#，但是基础太弱，在努力学习。加油

改天注释一下这个代码，然后去搬(jia)砖(ban)去喽……

#include <windows.h>
/*
Get System Infomation and Copy to a File
*/
int main(int argc, TCHAR argv [])
{
    // File Handle
    HANDLE hFile;
    DWORD dwWritten;
    // Char Array to Store the Path of the System Infomation
    TCHAR szSystemDir [MAX_PATH];
    //Get System Directory
    GetSystemDirectory(szSystemDir, MAX_PATH);

    //Creat File SystemRoot.txt
    hFile = CreateFile(
        "SystemRoot.txt",
        GENERIC_WRITE,
        0,NULL,CREATE_ALWAYS,
        FILE_ATTRIBUTE_NORMAL,
        NULL
        );
    if (hFile != INVALID_HANDLE_VALUE)
    {
        //Write the System Infomation to the File SystemRoot.txt
        if (!WriteFile(hFile, szSystemDir, lstrlen(szSystemDir), &dwWritten, NULL));
        {
            return GetLastError();
        }
    }
    //Close the File
    CloseHandle(hFile);
    return 0;
}
