C#获取句柄内容的相关问题

Question

通过spy++已经得到 TStringGrid 的句柄 用C# 如何能得到 TStringGrid 中的数据 谁有实例

Answer 1

参考一下这段代码

 以前做个这个，不过是C++的，使用了hook方法。
你可以参考
下载完了，运行Exec这个程序，是TStringGrid的示例，运行EnumControls.exe，
点击【列举窗体中的控件】按钮，就获取了TStringGrid的句柄，
点击【复制SG中的数据】就可以把Exec这个程序中TStringGrid的数据复制到EnumControls.exe了。
核心代码是这个：
HWND DLLHWND; 
    void __stdcall (*InstallHook)(HWND, HWND);
    void __stdcall (*UninstallHook)();
    char * __stdcall (*GetHookedCell)();

    DLLHWND = LoadLibrary("HookSG.dll");
    InstallHook = (void (__stdcall *)(HWND, HWND))GetProcAddress(DLLHWND, "InstallHook");
    UninstallHook = (void (__stdcall *)())GetProcAddress(DLLHWND, "UninstallHook");
    GetHookedCell = (char * (__stdcall *)())GetProcAddress(DLLHWND, "GetHookedCell");

    //AnsiString StrHwnd = SG->Cells[2][SelectedRow];
    //if (StrHwnd == "") return;
    //HWND hWnd = (void *)(StrHwnd.ToInt());
    //HWND hParent = GetParent(hWnd);

    //HWND hParent = FindWindow("TForm1", "列举窗体中的控件");
    //HWND hParent = FindWindow("TForm1", "Form1");
    //HWND hParent = FindWindow("TFrmSGHooked", "StringGrid to be hooked");
    char cText[MAX_PATH] = {0};
    strcpy(cText, Edit1->Text.c_str());
    if (strcmp(cText, "") == 0) return;
    HWND hParent = FindWindow(NULL, cText);
    HWND hWnd = FindWindowEx(hParent, 0, "TStringGrid", NULL);
    if (!hWnd) return;
    InstallHook(Handle, hWnd);
    SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0);
    PostMessage(hParent, WM_NULL, 0, 0);

    for (int i = 0; i < 20; i++)
    {
        Sleep(100);
        Application->ProcessMessages();
        if (MsgWnd != 0) break;
    }
    if (MsgWnd == 0) goto Exit;

    int iRow, iCol, iLen;
    iRow = SendMessage(MsgWnd, CM_QUERYROW, 0, 0);
    iCol = SendMessage(MsgWnd, CM_QUERYCOL, 0, 0);
    if (iRow <= 0 || iCol <= 0) goto Exit;
    SGSub->RowCount = iRow;
    SGSub->ColCount = iCol;
    for (int i = 0; i < iRow; i++)
    {
        for (int j = 0; j < iCol; j++)
        {
            iLen = SendMessage(MsgWnd, CM_HOOKCELL, j, i);
            if (iLen < 0) goto Exit;
            SGSub->Cells[j][i] = GetHookedCell();
        }
    }

  Exit:
  MsgWnd = 0;
  UninstallHook();
  SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0);
  FreeLibrary(DLLHWND);
