void __fastcall TForm1::Button1Click(TObject *Sender)
{
    char szFile[64];
    HANDLE handle;
    unsigned long lWritten,lRead;

    if (!DirectoryExists("c://zhangyan"))  //判斷是否存在目錄
    {
        CreateDir("C://zhangyan");          //創建目錄
    }

    handle = CreateFile("c://s4gg//s4gg.txt",GENERIC_READ|GENERIC_WRITE,FILE_SHARE_READ,NULL,OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,0);

    if(handle==INVALID_HANDLE_VALUE)
    {
        MessageBox(NULL,"Error Create File!","Error",MB_OK);

    else
    MessageBox(NULL,"Open file Success!","Open file",MB_OK);
