我是2天的.NET C#编码器试图从 ProjectB - C#控制台应用程序控制 ProjectA - WinForm 。
基本上我正在使用WatiN在ProjectA中的WebBrowser控件中自动执行测试。
当我运行执行winformWithWebBrowserTest.exe的ProjectB时,带有webbrowser的winform显示出来。但后来它无法访问form1。如何从ProjectB ???
访问webbrowser控件错误:
System.Runtime.IteropServices.InvalidComObjectException
COM
object that has been separated from its underlying RCW cannot be used
ProjectA WinForm:(winformWithWebBrowserTest.exe)
namespace WindowsFormsApplication1
{
public partial class Form1 : System.Windows.Forms.Form
{
public Form1()
{
InitializeComponent();
}
}//end class
}//end namespace
项目B控制台应用:(WatinConsoleExample.cs)
namespace ConsoleApplication1
{
class WatinConsoleExample
{
[STAThread]
static void Main(string[] args)
{
//run ProjectA exe
System.Diagnostics.Process Proc = new System.Diagnostics.Process();
Proc.StartInfo.FileName = "C:\\Users\\m-takayashiki\\Documents\\Visual Studio 2010\\Projects\\winformWithWebBrowserTest\\winformWithWebBrowserTest\\bin\\Release\\winformWithWebBrowserTest.exe";
Proc.Start();
WindowsFormsApplication1.Form1 form1 = new Form1();
var t = new Thread(() =>
{
Settings.AutoStartDialogWatcher = false;
//exception occurs below ..........
var ie = new IE(form1.webBrowser1.ActiveXInstance);
ie.GoTo("http://www.google.com");
ie.TextField(Find.ByClass("lst")).TypeText("this is awesome!!");
ie.Button(Find.ByName("btnG")).Click();
});
t.SetApartmentState(ApartmentState.STA);
t.Start();
}
}
}

你不能这样做,因为这两个进程都在它们各自的进程空间中运行。你需要重新进行2天内不建议的进程间通信:)。
