[Agrestic]

i am using AxWebBrowser in C# project. i add and on click event handler on the document on Document Completed event. code is given below

mshtml.HTMLDocument doc1=(mshtml.HTMLDocument)axWebBrowser1.Document;
mshtml.HTMLDocumentEvents2_Event eve=(mshtml.HTMLDocumentEvents2_Event)doc1;
eve.onclick+=new HTMLDocumentEvents2_onclickEventHandler(eve_onclic k);

its firing ok but the problem is this that if i click a text box, it doesnt get the focus and i cannot type in it.

i will be very thankfull if anyone can help me out here.

What does this onclick event do?

[Agrestic]

it gets the element clicked, then search in the Treeview created from html returned and returns wether its the same one or not.



i removed this handler DocumentComplete event handler and all the things returned to normal. i mean to say that text boxes got their focus.i then put the same code in NavigateComplete2 event and it seized to work again.

[kenobewan]

Please post the code for the event, I assume that you mean ceased.

[Agrestic]

yes i meant cease. and the code u asked for. its given below

private void axWebBrowser1_DocumentComplete(object sender, System.EventArgs e)
        {
            progressBar1.Increment(progressBar1.Minimum+=15);
            string url=axWebBrowser1.LocationURL;
            prurl=url;
 
            this.comboBox1.Items.Add(axWebBrowser1.LocationURL);
            ImageList ls=new ImageList();
            ls.Images.Add(Image.FromFile("exxp.gif"));
            ls.Images.Add(Image.FromFile("txt.gif"));
            treeView.ImageList=ls;
            if(newproject)
            {
                newproject=false;
                TreeNode tnod=new TreeNode("Sequence ");
                tnod.Nodes.Add(new TreeNode(url,1,1));
                treeView.Nodes.Add(tnod);
            }
            else
            {
                treeView.Nodes[0].Nodes.Add(new TreeNode(url,1,1));
            }
 
            mshtml.HTMLDocument doc1=(mshtml.HTMLDocument)axWebBrowser1.Document;
            mshtml.HTMLDocumentEvents2_Event eve=(mshtml.HTMLDocumentEvents2_Event)doc1;
            eve.onclick+=new HTMLDocumentEvents2_onclickEventHandler(eve_onclick);
 
            status="Done";
            sbstatus.Text="Done";
            string code=this.LoadFile();
            if(!code.Equals(""))
            {
                IHTMLDocument2 doc = (IHTMLDocument2) this.axWebBrowser1.Document;
                if (doc != null)
                {
                    IHTMLWindow2 parentWindow = doc.parentWindow;
                    if (parentWindow != null)
                        parentWindow.execScript(code, "javascript");
                }
            }
            Cursor.Current = Cursors.Default;
            progressBar1.Increment(progressBar1.Minimum+=20);
            string a=this.axWebBrowser1.LocationURL.ToString();        
            this.sbstatus.Text="Loading..."+a;
            this.comboBox1.SelectedItem=a;
            show_html_code(a);
            this.ProcessHTML(htmlCode);                    
            count++;    
 
        }

Please post the eve_onclick event code. Thanks.

[Agrestic]

sorry i misunderstood. here is the code for onclick event

private bool eve_onclick(IHTMLEventObj pEvtObj)
        {
 
            if(RecOn)
            {
 
                //DataRow dr=dtrob.NewRow();
                if(rdbdload.Checked)
                {
                    //dr[0]=act;
                }
                else if(rdbfrmsmt.Checked)
                {
                    //dr[0]=act;
                }
                else if(rbnav.Checked)
                {
                    //dr[0]=act;
                }
                else if(rdbtxtext.Checked)
                {
                    //dr[0]=act;
                }
                else
                {    
                    MessageBox.Show("Please select an action from the given options","Info Message",MessageBoxButtons.RetryCancel,MessageBoxIcon.Information);
                    return false;
                }
 
                HtmlParser parser=new HtmlParser();
                mshtml.IHTMLElement ele=pEvtObj.srcElement;            
                string strrr=ele.outerHTML;
                HtmlDocument ddoc=HtmlDocument.Create(strrr,false);
                TreeNode tnod=tvwDOM.Nodes[0];
                HtmlNodeCollection hnod=ddoc.Nodes;
                //If HtmlDocument contains only one parent node for such nodes which can be converted to DOM otherwise all nodes are given 
 
                builder.Clear();
                if(hnod.Count>1)
                {
                    for(int n=0;n<hnod.Count;n++)
                    {
                        HtmlNode nn=hnod[n];
                        builder.Add(nn.ToString());    
                    }
                }
                else
                {                        
                    Builder(ddoc.Nodes[0],true,"nor");
                }
                builder.TrimToSize();
                URList.Add(prurl);
                tnod=check(tnod,builder,true);/// this function searches a tree and return the node of the tree being searched
                if(tnod!=null)
                {    
                    string str=tnod.FullPath;
                    drrob[2]=str;
                    URList.Add(str);
                }
                else
                {
                            /// Node not found    
                            URList.Add(null);
                }    
                //System.Xml.XmlTextWriter twriter=new XmlTextWriter(
                drrob[3]=axWebBrowser1.LocationURL;
                dtrob.Rows.Add(drrob);
            }    
 
            return true;
        }

i removed this handler DocumentComplete event handler and all the things returned to normal. i mean to say that text boxes got their focus.i then put the same code in NavigateComplete2 event and it seized to work again.

I can't see the NavigateComplete2 event in your code, did you take it out to show the rest of the code?

[Agrestic]

iam sending all the events i defined on the axsebbrowser

private void axWebBrowser1_NavigateComplete2(object sender, AxSHDocVw.DWebBrowserEvents2_NavigateComplete2Even t e)
{
status=sbstatus.Text;
string a=this.axWebBrowser1.LocationURL.ToString();
//show_html_code(a);
progressBar1.Increment(progressBar1.Minimum+=15);

}

private void axWebBrowser1_BeforeNavigate2(object sender, AxSHDocVw.DWebBrowserEvents2_BeforeNavigate2Event e)
{
string urlsrt=e.uRL.ToString();
progressBar1.Increment(progressBar1.Minimum+=15);
}


rest u already have.

[kenobewan]

I believe that NavigateComplete2 is not the right event to use here. If navigation to a site is successful, the NavigateComplete2 handler is called, if available. Here is an article that may help:
Component-Based Development with Visual C#

[Agrestic]

actually i am using navigate event to increment the status bar.
All three of the events fire.
the link u sent me is very helpful. i am trying to sort out the problem but still not a solution yet.
