遍歷窗口，獲得控件句柄

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

回調函數

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);//添加標題 8 EnumProgress(hwnd);//添加內容 9 return true;//結束遍歷 10 } 11 12 return false;//繼續遍歷子窗口 13 }

添加標題

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 = "父進程PID"; 10 lvc.cx = 100; 11 SendMessage(hList, LVM_INSERTCOLUMN, 1, (long)&lvc); 12 lvc.pszText = "映像名稱"; 13 lvc.cx = 200; 14 SendMessage(hList, LVM_INSERTCOLUMN, 2, (long)&lvc); 15 }

添加內容

1 BOOL EnumProgress(HWND hList) 2 { 3 BOOL bRet = FALSE; 4 HANDLE hProcessSnap = NULL; 5 6 hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); 7 if (hProcessSnap == INVALID_HANDLE_VALUE) 8 { 9 return FALSE; 10 } 11 12 PROCESSENTRY32 pe32 = {0}; 13 pe32.dwSize = sizeof(PROCESSENTRY32); 14 if (Process32First(hProcessSnap, &pe32)) 15 { 16 LVITEM lvi = {0}; 17 lvi.mask = LVIF_TEXT; 18 char strTmp[MAXBYTE] = {0}; 19 do 20 { 21 ZeroMemory(strTmp, MAXBYTE); 22 sprintf(strTmp, "%d", pe32.th32ProcessID); 23 lvi.iItem = 0; 24 lvi.iSubItem = 0;//發送LVM_INSERTITEM消息時，subitem必須為0 25 lvi.pszText = strTmp; 26 int nIndx = SendMessage(hList, LVM_INSERTITEM, 0, (LPARAM)&lvi);//返回值為item的索引 27 28 ZeroMemory(strTmp, MAXBYTE); 29 sprintf(strTmp, "%d", pe32.th32ParentProcessID); 30 lvi.iItem = nIndx; 31 lvi.iSubItem = 1; 32 lvi.pszText = strTmp; 33 SendMessage(hList, LVM_SETITEM, 0, (LPARAM)&lvi); 34 35 lvi.iSubItem = 2; 36 lvi.iItem = nIndx; 37 lvi.pszText = pe32.szExeFile; 38 SendMessage(hList, LVM_SETITEM, 0, (LPARAM)&lvi); 39 } 40 while (Process32Next(hProcessSnap, &pe32)); 41 bRet = TRUE; 42 } 43 else 44 { 45 bRet = FALSE; 46 } 47 48 CloseHandle (hProcessSnap); 49 return bRet; 50 }
