VC获取其他进程ListCtrl内容
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
VC讀寫其他進程ListCtrl數據到本進程的實例，下面用Windows任務管理器來做測試：
1、捕獲窗口句柄：
???? 用SPY++可以看到如下父子窗口關系：
???
???? 添加ListCtrl，設置style / Report、關聯控件變量m_ListCtrl，再添加一個按鈕，如下圖：
???
2、相關代碼：
view plaincopy to clipboardprint?

view plaincopy to clipboardprint? void?CTestDlg::OnBtnRead()??? {?? ?????? ????m_ListCtrl.DeleteAllItems();?? ?????? ?????? ????HWND????hWnd,hListview;?? ????hWnd=::FindWindow(NULL,_T("Windows?任務管理器"));????? ????hWnd=::FindWindowEx(hWnd,0,"#32770",0);????? ????hListview=::FindWindowEx(hWnd,0,_T("SysListView32"),NULL);?? ????if(!hListview)?? ????{?? ????????MessageBox("Listview?handle?is?NULL?！");?? ????????return;?? ????}?? ?? ????int?count?=?(int)::SendMessage(hListview,LVM_GETITEMCOUNT,0,0);?? ????int?i,nItem;?? ?? ?????? ????CString?strTemp;?? ????strTemp.Format("總共%d行記錄",count);?? ????MessageBox(strTemp);?? ?????? ????CString?str1="";?? ????CString?str2="";?? ????CString?str3="";?? ????CString?str4="";?? ?? ????DWORD???pid;?? ????HANDLE??process;?? ????LVITEM??lvi,?*_lvi;?? ????char????firstitem[512],?secitem[512],thirditem[512],fourthitem[512];?? ????char????*_firstitem,?*_secitem,*_thirditem,*_fourthitem;?? ?? ????memset(firstitem,0,512);?? ????memset(secitem,0,512);?? ????memset(thirditem,0,512);?? ????memset(fourthitem,0,512);?? ?? ?????? ????GetWindowThreadProcessId(hListview,?&pid);?? ????process=OpenProcess(PROCESS_VM_OPERATION|PROCESS_VM_READ|?? ????????PROCESS_VM_WRITE|PROCESS_QUERY_INFORMATION,?FALSE,?pid);?? ?????? ?????? ????_lvi=(LVITEM*)VirtualAllocEx(process,?NULL,?sizeof(LVITEM),MEM_COMMIT,?PAGE_READWRITE);?? ????_firstitem=(char*)VirtualAllocEx(process,?NULL,?512,?MEM_COMMIT,PAGE_READWRITE);?? ????_secitem??=(char*)VirtualAllocEx(process,?NULL,?512,?MEM_COMMIT,PAGE_READWRITE);?? ????_thirditem=(char*)VirtualAllocEx(process,?NULL,?512,?MEM_COMMIT,PAGE_READWRITE);?? ????_fourthitem=(char*)VirtualAllocEx(process,NULL,?512,?MEM_COMMIT,PAGE_READWRITE);?? ????lvi.cchTextMax=512;?? ?? ?????? ????for(i=count;?i>=0;?i--)?? ????{?? ?????????? ????????lvi.iSubItem=0;?? ????????lvi.pszText=_firstitem;?? ????????WriteProcessMemory(process,?_lvi,?&lvi,?sizeof(LVITEM),?NULL);?? ????????::SendMessage(hListview,?LVM_GETITEMTEXT,?(WPARAM)i,?(LPARAM)_lvi);?? ?????????? ?????????? ????????lvi.iSubItem=1;?? ????????lvi.pszText=_secitem;?? ????????WriteProcessMemory(process,?_lvi,?&lvi,?sizeof(LVITEM),?NULL);?? ????????::SendMessage(hListview,?LVM_GETITEMTEXT,?(WPARAM)i,?(LPARAM)_lvi);?? ?????????? ?????????? ????????lvi.iSubItem=2;?? ????????lvi.pszText=_thirditem;?? ????????WriteProcessMemory(process,?_lvi,?&lvi,?sizeof(LVITEM),?NULL);?? ????????::SendMessage(hListview,?LVM_GETITEMTEXT,?(WPARAM)i,?(LPARAM)_lvi);?? ?? ?????????? ????????lvi.iSubItem=3;?? ????????lvi.pszText=_fourthitem;?? ????????WriteProcessMemory(process,?_lvi,?&lvi,?sizeof(LVITEM),?NULL);?? ????????::SendMessage(hListview,?LVM_GETITEMTEXT,?(WPARAM)i,?(LPARAM)_lvi);?? ?? ?????????? ????????ReadProcessMemory(process,?_firstitem,??firstitem,??512,?NULL);?? ????????ReadProcessMemory(process,?_secitem,????secitem,????512,?NULL);?? ????????ReadProcessMemory(process,?_thirditem,??thirditem,??512,?NULL);?? ????????ReadProcessMemory(process,?_fourthitem,?fourthitem,?512,?NULL);?? ?? ?????????? ????????str1.Format("%s",firstitem);?? ????????str2.Format("%s",secitem);?? ????????str3.Format("%s",thirditem);?? ????????str4.Format("%s",fourthitem);?? ?? ?????????? ????????nItem?=?m_ListCtrl.InsertItem(0,str1);?? ????????m_ListCtrl.SetItem(nItem,1,1,str2,NULL,0,0,0);?? ????????m_ListCtrl.SetItem(nItem,2,1,str3,NULL,0,0,0);?? ????????m_ListCtrl.SetItem(nItem,3,1,str4,NULL,0,0,0);?? ????}?? ?? ?????? ????VirtualFreeEx(process,?_lvi,????????0,?MEM_RELEASE);?? ????VirtualFreeEx(process,?_firstitem,??0,?MEM_RELEASE);?? ????VirtualFreeEx(process,?_secitem,????0,?MEM_RELEASE);?? ????VirtualFreeEx(process,?_thirditem,??0,?MEM_RELEASE);?? ????VirtualFreeEx(process,?_fourthitem,?0,?MEM_RELEASE);?? }??
讀取文件列表：
view plaincopy to clipboardprint? void?CTestDlg::OnBtnReadFile()??? {?? ?????? ????m_ListCtrl.DeleteAllItems();?? ????int?nRow;?? ????int?j;?? ????nRow?=?m_ListCtrl.GetHeaderCtrl()->GetItemCount();?? ????for(j=0;j<=nRow;j++)?? ????{?? ????????m_ListCtrl.DeleteColumn(0);?? ????}?? ?? ?????? ????m_ListCtrl.InsertColumn(0,"文件名稱",NULL,80,?-1);?? ????m_ListCtrl.InsertColumn(1,"大小",NULL,60,-1);?? ????m_ListCtrl.InsertColumn(2,"類型",NULL,100,-1);?? ????m_ListCtrl.InsertColumn(3,"修改日期",NULL,120,-1);?? ?????? ?????? ????HWND????hWnd,hListview;?? ????hWnd=::FindWindow(NULL,_T("C:\\Documents?and?Settings\\Koma\\桌面\\Test"));????? ????hWnd=::FindWindowEx(hWnd,0,_T("SHELLDLL_DefView"),0);?? ????hWnd=::FindWindowEx(hWnd,0,_T("DUIViewWndClassName"),0);?? ????hWnd=::FindWindowEx(hWnd,0,_T("DirectUIHWND"),0);?? ????hWnd=::FindWindowEx(hWnd,0,_T("CtrlNotifySink"),0);?? ????hListview=::FindWindowEx(hWnd,0,_T("SysListView32"),NULL);?? ????if(!hListview)?? ????{?? ????????MessageBox("Listview?handle?is?NULL?！");?? ????????return;?? ????}?? ????......?? }??
3、程序運行效果：
???
??
4、程序不足：
???? A、在獲取任務管理器“進程”標簽內容時，因為有些列表項沒有顯示、即它的iSubItem項被設置隱藏（設置為0寬度即可），所以需要在“查看”/ “選擇列”打開相關選項，不然你可能會覺得程序讀錯。（如果切換成“用戶”標簽則不會.）
???? B、在獲取SysListView32句柄時，有些程序的ListCtrl某些列是可編輯的，這里我還沒有搞明白為什么可編輯的沒有獲取到，比如像這樣的：
???
????
?（比如文件列表試圖里，文件名是可以編輯的，獲取這個又沒有問題，這個編輯區域有點像個指定大小的EditBox，不知道這程序是如何重寫的CListCtrl類，或是那個開源的項目，見過或用過的友友請說聲哈！）
這種可編輯的ListCtrl內容該怎么獲取，哪位兄弟知道的，麻煩你有空請告訴我一聲吧！
