SDK 操作 list-view control 实例 -- 遍历进程

遍历窗口，获得控件句柄

1 EnumChildWindows(hwndDlg, (WNDENUMPROC)EnumChildProc, NULL);

回调函数

 1 BOOL CALLBACK EnumChildProc(HWND hwnd, LPARAM lParam )
 2 {
 3     char strCLSName[MAXBYTE] = {0};
 4     GetClassName(hwnd, strCLSName, MAXBYTE);
 5     if (strcmp(strCLSName, "SysListView32") == 0)//找到列表控件
 6     {
 7         InsertColumn(hwnd);//添加标题
 8         EnumProgress(hwnd);//添加内容
 9         return true;//结束遍历
10     }
11 
12     return false;//继续遍历子窗口
13 }

添加标题

 1 void InsertColumn(HWND hList)
 2 {
 3     LV_COLUMN lvc = {0};
 4     
 5     lvc.mask = LVCF_TEXT | LVCF_WIDTH;
 6     lvc.pszText = "PID";
 7     lvc.cx = 80;
 8     SendMessage(hList, LVM_INSERTCOLUMN, 0, (long)&lvc);
 9     lvc.pszText = "父进程PID";
10     lvc.cx = 100;
11     SendMessage(hList, LVM_INSERTCOLUMN, 1, (long)&lvc);
12     lvc.pszText = "映像名称";
13     lvc.cx = 200;
14     SendMessage(hList, LVM_INSERTCOLUMN, 2, (long)&lvc);
15 }
