Tools

 1. DebugView，输出调试信息（不能F5，而是要Ctrl + F5，F5输出到VC的debug窗口）

 1 void DbgPrint(char* pFMT, ...)
 2 {
 3     char szBuf[1024] = {0};
 4     va_list lst;
 5     va_start(lst, pFMT);
 6     vsprintf(szBuf, pFMT, lst);
 7     va_end(lst);
 8     
 9     OutputDebugString(szBuf);
10 }

 2. C语言，拼接字符串

 1 //使用后要free
 2 char* split(char* a, char* b) 
 3 {  
 4     char* c = (char*)malloc(strlen(a) + strlen(b) + 1);
 5     if (c == NULL) 
 6     {
 7         return NULL;
 8     }
 9     
10     char* tempc = c;
11     while (*a != '\0') 
12     {  
13         *tempc++ = *a++;  
14     }  
15     while ((*tempc++ = *b++) != '\0');
16     
17     return c;
18 }

 3. 响应 WM_DROPFILES 消息（#define WM_DROPFILES 0x0233）

1）MFC版

 1 void CTestDlg::OnDropFiles(HDROP hDropInfo) 
 2 {
 3     char szPath[MAX_PATH] = {0};
 4     
 5     DragQueryFile(hDropInfo, NULL, szPath, sizeof(szPath) / sizeof(*szPath));
 6     DragFinish(hDropInfo);
 7     
 8     SetDlgItemText(IDC_EDT_PATH, szPath);
 9 
10     CDialog::OnDropFiles(hDropInfo);
11 }

 2）SDK版

 1 case WM_DROPFILES:
 2 {
 3     char szPath[MAX_PATH] = {0};
 4 
 5     DragQueryFileA((HDROP)wParam, NULL, szPath, sizeof(szPath) / sizeof(*szPath));
 6     DragFinish((HDROP)wParam);
 7 
 8     HWND hEdit = GetDlgItem(hwnd, IDC_EDT_PATH);
 9     SetWindowTextA(hEdit, szPath);
10     
11     break;
12 }
