How to get the Query String parameters, in a new tab, from the IEModule loaded into that tab?

Hi Guys,
Any thoughts on how to get the query string parameters of a url loaded in a new window/process?

Here is the flow of my IE Addon:

1.)Open IE for the first time and the first ADXIEModule instance is instantiated/loaded.
2.)The first ADXIEModule instance will call IEApp.Navigate(newUrlWithQueryStringParams, ref flags, target); //where object flags = null; object target = "_blank";
3.)Now a new tab opens, which instantiates a second ADXIEModule instance.

From the *second* ADXIEModule instance, how can I know the query string parameters?
BeforeNavigate2 event does not fire in the second instance..but only the first instance.

I'm looking for a way to identify from the second instance, that it was the one opened by original Navigate call.

Any thoughts on how to do this?

Hi Jonathan,

Please try the code below: 

        private string targetURL = String.Empty;

        public string GetTargetURL()
        {
            string _temp = this.targetURL;
            this.targetURL = String.Empty;

            return _temp;
        }

        private void adxieContextMenuCommandItem2_OnClick(object sender, object htmlElement)
        {
            object flags = null; object target = "_blank";
            this.targetURL = "//www.add-in-express.com/forum/read.php?FID=10&TID=11737&MID=59783#message59783";

            IEApp.Navigate("about:blank?threadID=" + this.ThreadID.ToString() + "&processID=" + this.ProcessID.ToString(), ref flags, target);
        }

        private void IEModule_DocumentComplete(object pDisp, string url)
        {
            if (!String.IsNullOrEmpty(url))
            {
                if (url.StartsWith("about:blank?threadID=", StringComparison.InvariantCultureIgnoreCase))
                {
                    int tabThreadID = 0;
                    int tabProcessID = 0;

                    try
                    {
                        string callerIDs = url.Replace("about:blank?", String.Empty);
                        string[] parts = callerIDs.Split('&');
                        tabThreadID = int.Parse(parts[0].Replace("threadID=", String.Empty));
                        tabProcessID = int.Parse(parts[1].Replace("processID=", String.Empty));
                    }
                    catch (Exception)
                    {
                    }

                    if (tabThreadID != 0 && tabProcessID != 0)
                    {
                        string newUrlWithQueryStringParams = String.Empty;

                        ArrayList modules = ADXIEModule.GetModulesByTypeName(this.GetType().FullName);
                        foreach (ADXIEModule m in modules)
                        {
                            if (m.ThreadID == tabThreadID && m.ProcessID == tabProcessID)
                            {
                                newUrlWithQueryStringParams = ((IEModule)m).GetTargetURL();
                                break;
                            }
                        }

                        if (!String.IsNullOrEmpty(url))
                        {
                            object flags = null; object target = "_self";
                            IEApp.Navigate(newUrlWithQueryStringParams, ref flags, target);
                        }
                    }
                }
            }
        }

Seems to be a typo:

this.targetURL = ";;

is that meant to be this.targetURL = ";;" ? or this.targetURL = ""; ?

Thanks Sergey, this will work perfectly!

The reason DocumentComplete never fired on the newly opened form, was because of the redirect that page is doing. Opening to about:blank first allows the load to finish..thereby firing DocumentComplete, which has all the query string parameters.

Thank you so much!
