一、簡述

? ? ? ? 記--使用開源MD5計算代碼+MFC實現簡單的文件MD5計算器。

????????1、支持拖拽文件或目錄。
????????2、支持拖拽多個文件或目錄。
????????3、支持比較兩個MD5值，不一致時指出第幾個字符不一致。
????????4、支持輸出文件全路徑或僅文件名。
????????5、支持輸出文件大小。
????????6、支持指定文件后綴。

例子打包：外鏈:https://wwi.lanzouq.com/b0c9zap6d?密碼:d49u

C語言開源MD5代碼：https://github.com/chinaran/Compute-file-or-string-md5

二、效果

五、總結

5.1?文件拖拽
? ? 添加ON_WM_DROPFILES消息處理：OnDropFiles()
?? ?窗口Accept file屬性設置為true

5.2?窗口屏蔽回車關閉（默認在窗口、Edit控件按回車回關閉窗口）
?? ?edit、wantreturn屬性設置為true
?? ?重寫窗口onOK處理?

?

5.3 復制內容到粘貼板，

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();}

粘貼出來只有一個字節時可右鍵項目--屬性--設置字符集為使用多字節字符集

5.4 獲取/設置控件位置

//獲取相對于父窗口位置 CRect rect; GetDlgItem(IDC_STATIC_FileType)->GetWindowRect(&rect); ScreenToClient(&rect);//轉換為相對于父窗口的位置 int x = rect.left; int y = rect.top;//設置子控件的位置(相對于父窗口位置)//將文件后綴移動臺"復制MD5值"右邊 IDC_STATIC_FileType是控件IDGetDlgItem(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);//設置主窗口大小但不移動位置 SetWindowPos(NULL, 0, 0, 586, 380, SWP_NOMOVE);//設置窗口寬高但不移動位置SWP_NOMOVE：忽略x、y，維持位置不變； SWP_NOSIZE：忽略cx、cy，維持大小不變；

==============================修改版==============================

例子打包：外鏈:https://wwi.lanzouq.com/b0c9zap6d?密碼:d49u

修改點：

1、默認不清空結果，方便比較多個文件的md5值。

2、結果信息輸出后自動滾動到底部，方便查看最新的文件MD5及文件個數。

3、將文件后綴設置移到右邊隱藏區，放大窗口可見。
