MFC 简单的MD5计算器
时间：03-17来源：作者：点击数：
一、简述
记--使用开源MD5计算代码+MFC实现简单的文件MD5计算器。
1、支持拖拽文件或目录。
2、支持拖拽多个文件或目录。
3、支持比较两个MD5值，不一致时指出第几个字符不一致。
4、支持输出文件全路径或仅文件名。
5、支持输出文件大小。
6、支持指定文件后缀。
例子打包：外链:https://wwi.lanzouq.com/b0c9zap6d密码:d49u
C语言开源MD5代码：https://github.com/chinaran/Compute-file-or-string-md5
二、效果
三、代码工程

五、总结
5.1文件拖拽
添加ON_WM_DROPFILES消息处理：OnDropFiles()
窗口Accept file属性设置为true
5.2窗口屏蔽回车关闭（默认在窗口、Edit控件按回车回关闭窗口）
edit、wantreturn属性设置为true
重写窗口onOK处理
5.3 复制内容到粘贴板，
CString MD5String = "abc123";
if (OpenClipboard())
{
UpdateData(true);
HGLOBAL clipbuffer;
char* buffer = NULL;
EmptyClipboard();
clipbuffer = GlobalAlloc(GMEM_DDESHARE, MD5String.GetLength() + 1);
buffer = (char*)GlobalLock(clipbuffer);
strcpy_s(buffer, MD5String.GetLength() + 1, (LPSTR)(LPCTSTR)MD5String);
GlobalUnlock(clipbuffer);
SetClipboardData(CF_TEXT, clipbuffer);
CloseClipboard();
}
粘贴出来只有一个字节时可右键项目--属性--设置字符集为使用多字节字符集
5.4 获取/设置控件位置
//获取相对于父窗口位置
CRect rect;
GetDlgItem(IDC_STATIC_FileType)->GetWindowRect(&rect);
ScreenToClient(&rect);//转换为相对于父窗口的位置
int x = rect.left;
int y = rect.top;
//设置子控件的位置(相对于父窗口位置)
//将文件后缀移动台"复制MD5值"右边 IDC_STATIC_FileType是控件ID
GetDlgItem(IDC_STATIC_FileType)->SetWindowPos(NULL, 440, 23, 0, 0, SWP_NOZORDER | SWP_NOSIZE);
GetDlgItem(IDC_EDIT_FileExtension)->SetWindowPos(NULL, 512, 18, 0, 0, SWP_NOZORDER | SWP_NOSIZE);
//设置主窗口大小但不移动位置
SetWindowPos(NULL, 0, 0, 586, 380, SWP_NOMOVE);//设置窗口宽高但不移动位置
SWP_NOMOVE：忽略x、y，维持位置不变；
SWP_NOSIZE：忽略cx、cy，维持大小不变；
==============================修改版==============================
例子打包：外链:https://wwi.lanzouq.com/b0c9zap6d密码:d49u
修改点：
1、默认不清空结果，方便比较多个文件的md5值。
2、结果信息输出后自动滚动到底部，方便查看最新的文件MD5及文件个数。
3、将文件后缀设置移到右边隐藏区，放大窗口可见。
