如何利用Win32API取得另一支程式中的ListView內的所有值

uses CommCtrl;function ListViewColumnCount(mHandle: THandle): Integer;begin Result := Header_GetItemCount(ListView_GetHeader(mHandle));end; { ListViewColumnCount }function GetListViewSelectText(mHandle: THandle;var mStrings: string): Boolean;var vColumnCount: Integer; vItemCount: Integer; I, J: Integer; vBuffer: array[0..255] of Char; vProcessId: DWORD; vProcess: THandle; vPointer: Pointer; vNumberOfBytesRead: Cardinal; S: string; vItem: TLVItem;begin Result := False; I := ListView_GetNextItem(mHandle, -1, LVNI_SELECTED); if I = -1 then Exit;// if not Assigned(mStrings) then Exit; vColumnCount := ListViewColumnCount(mHandle); if vColumnCount <= 0 then Exit;// vItemCount := ListView_GetItemCount(mHandle); GetWindowThreadProcessId(mHandle, @vProcessId); vProcess := OpenProcess(PROCESS_VM_OPERATION or PROCESS_VM_READ or PROCESS_VM_WRITE, False, vProcessId); vPointer := VirtualAllocEx(vProcess, nil, 4096, MEM_RESERVE or MEM_COMMIT, PAGE_READWRITE);// mStrings.BeginUpdate; try// mStrings.Clear; mStrings := ''; for J := 0 to vColumnCount - 1 do begin with vItem do begin mask := LVIF_TEXT; iItem := I; iSubItem := J; cchTextMax := SizeOf(vBuffer); pszText := Pointer(Cardinal(vPointer) + SizeOf(TLVItem)); end; WriteProcessMemory(vProcess, vPointer, @vItem, SizeOf(TLVItem), vNumberOfBytesRead); SendMessage(mHandle, LVM_GETITEM, I, lparam(vPointer)); ReadProcessMemory(vProcess, Pointer(Cardinal(vPointer) + SizeOf(TLVItem)), @vBuffer[0], SizeOf(vBuffer), vNumberOfBytesRead); mStrings := mStrings + #9 + vBuffer; end; finally VirtualFreeEx(vProcess, vPointer, 0, MEM_RELEASE); CloseHandle(vProcess);// mStrings.EndUpdate; end; Result := True;end; { GetListViewText }function GetListViewText(mHandle: THandle; mStrings: TStrings): Boolean;var vColumnCount: Integer; vItemCount: Integer; I, J: Integer; vBuffer: array[0..255] of Char; vProcessId: DWORD; vProcess: THandle; vPointer: Pointer; vNumberOfBytesRead: Cardinal; S: string; vItem: TLVItem;begin Result := False; if not Assigned(mStrings) then Exit; vColumnCount := ListViewColumnCount(mHandle); if vColumnCount <= 0 then Exit; vItemCount := ListView_GetItemCount(mHandle); GetWindowThreadProcessId(mHandle, @vProcessId); vProcess := OpenProcess(PROCESS_VM_OPERATION or PROCESS_VM_READ or PROCESS_VM_WRITE, False, vProcessId); vPointer := VirtualAllocEx(vProcess, nil, 4096, MEM_RESERVE or MEM_COMMIT, PAGE_READWRITE); mStrings.BeginUpdate; try mStrings.Clear; for I := 0 to vItemCount - 1 do begin S := ''; for J := 0 to vColumnCount - 1 do begin with vItem do begin mask := LVIF_TEXT; iItem := I; iSubItem := J; cchTextMax := SizeOf(vBuffer); pszText := Pointer(Cardinal(vPointer) + SizeOf(TLVItem)); end; WriteProcessMemory(vProcess, vPointer, @vItem, SizeOf(TLVItem), vNumberOfBytesRead); SendMessage(mHandle, LVM_GETITEM, I, lparam(vPointer)); ReadProcessMemory(vProcess, Pointer(Cardinal(vPointer) + SizeOf(TLVItem)), @vBuffer[0], SizeOf(vBuffer), vNumberOfBytesRead); S := S + #9 + vBuffer; end; Delete(S, 1, 1); mStrings.Add(S); end; finally VirtualFreeEx(vProcess, vPointer, 0, MEM_RELEASE); CloseHandle(vProcess); mStrings.EndUpdate; end; Result := True;end; { GetListViewText }//Exampleprocedure TForm1.FormCreate(Sender: TObject);begin RegisterHotKey(Handle, 1, MOD_WIN, VK_F2);end;procedure TForm1.FormDestroy(Sender: TObject);begin UnRegisterHotKey(Handle, 1);end;procedure TForm1.WMHOTKEY(var Msg: TWMHOTKEY);begin case Msg.HotKey of 1: GetListViewText( WindowFromPoint(Point(Mouse.CursorPos.X, Mouse.CursorPos.Y)), MemoText.Lines); end;end;
