我正在开发可以优化我的工作的应用程序,它通过RDP到服务器的多个连接.到那时,我想做一个单一的Windows表单,向我显示所有服务器.据我所知-我想以编程方式在Windows窗体中添加AxMsRdpClient2或AxMsTscAxNotSafeForScripting控件.在开始时,我有一个Form1,我在其中保存我的凭据(IP,USER,PASS),并使用简单的FOR来将ActiveX Client添加到Form2中并连接到服务器.

这是我的问题.让我们在下面看我的代码.

从Form1()调用>

var btt = new RunRDP();
    for (int i = 0; i < 15; i++)
    {
        btt.PozitionMaster();
    } 

RunRDP类别：

private static int _count;
private static int _row = 4;
private static int _colum = 4;
private static int _objId;

public void PozitionMaster()
    {
        if (_count != 6)
        {
            UInitializer(_objId++, _row, _colum);
            _row += 196;
            _count++;

        }
        else
        {
            _colum += 196;
            _row = 4;
            _count = 0;
        }
    }

UInitializer函数：

public AxMsRdpClient2 rdpClient;

        public void UInitializer(int id, int x, int y)
        {
            Form2 ippo = new Form2();
            rdpClient = new AxMsRdpClient2();

            rdpClient.UserName = "username";
            rdpClient.Server = "192.168.0.100";
            rdpClient.Height = y;
            rdpClient.Width = x;

            rdpClient.BeginInit();
            rdpClient.CreateControl();


            if (ippo.InvokeRequired)
            {
                ippo.Invoke(new Action(() => ippo.Controls.Add(rdpClient)));
                ippo.Invoke(new Action(() => ippo.Update()));
            }
            else
            {
                ippo.Controls.Add(rdpClient);
            }

            //this.Controls.Add(rdpClient);

            rdpClient.AdvancedSettings2.RDPPort = 3389;
            rdpClient.AdvancedSettings2.ClearTextPassword = "hello_rdp";//     
            rdpClient.ColorDepth = 16;//     
            rdpClient.FullScreen = false;//     

            rdpClient.Connect();    
        }

得到那个错误：

    An unhandled exception of type 'System.Windows.Forms.AxHost.
InvalidActiveXStateException' occurred in AxInterop.MSTSCLib.dll

{"Exception of type 'System.Windows.Forms.AxHost+InvalidActiveXStateException' was thrown."}

解决方法:

当您在创建ActiveX控件的本机窗口之前开始使用它时,会引发InvalidActiveXStateException.直到您调用ippo.Show()之后,这种情况才会发生.在该语句之后移动关键属性分配和方法调用.
