Hi!
I've added a CommandItem to Internet Explorer 8, and when I click that CommandItem, I'm asking IE to navigate to a certain URL. However, the fails with the following information:
Exception Source: Interop.SHDocVw
Exception Type: System.Runtime.InteropServices.COMException
Exception Message: The requested resource is in use. (Exception from HRESULT: 0x800700AA)
Exception Target Site: Navigate
Even though the IEApp object has the property busy == true, the browser isn't doing anything, and the URL is about:blank.
This used to work in IE6 and IE7, but here it fails in IE8. Do I need to do something in particular when dealing with IE8, compared to IE7 and 6?
Best regards,
Christian |

Hi Christian.
I have just tested the IEApp.Navigate method. It works fine on my PC.
Please provide the code of the OnClick event handler. I will test it. |

This is the code of the onClick-handler:
private void adxieCommandItem1_OnClick(object sender, object e)
{
string sURL;
System.Object one = null;
System.Object two = null;
System.Object three = null;
System.Object four = null;
MessageBox.Show("Test");
sURL = "http://www.google.dk";
IEApp.Navigate(sURL, ref one, ref two, ref three, ref four);

Hi Christian.
Please try to open a url in the OnSendMessage event handler:
private void adxieCommandItem1_OnClick(object sender, object htmlDoc)
{
this.SendMessage(0x400 + 1000, IntPtr.Zero, IntPtr.Zero);
}
private void IEModule_OnSendMessage(AddinExpress.IE.ADXIESendMessageEventArgs e)
{
if (e.Message == 0x400 + 1000)
{
object dummy = Type.Missing;
try
{
IEApp.Navigate("//www.add-in-express.com", ref dummy, ref dummy, ref dummy, ref dummy);
}
catch (Exception err)
{
MessageBox.Show(err.Message);
}
}
} |

Hi Sergey,
That worked! Now I have another question (actually two):
1. Why does it work? Why is that different from just navigating from the OnClick event?
2. It looks like I'll have to select the values around "0x400 + 1000" with care. What do I need to be aware of here? Is there a valid space in e.Message I must stay within?
Best regards,
Christian |

Hi Christian.
1. When you run the code from the OnClick event, IE executes a jscript which in its turn runs your code.
I am not sure but probably the SendMessage method allows you to postpone the request until IE is available.
2. 0x400 is the WM_USER constant reserved in Win32 API for custom messages.
You should define your messages as WM_USER + <an integer value>. |
