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 }

添加内容
