PONavigating to selected ListViewItem on doubleclick

Body
copied!<p>I'm making a simple browser in Visual Studio.<br> To be able to save and delete bookmarks, I'm using these codes:</p> <p>When the frmFavorites is opened, it'll read an xml-file named Favorites.xml</p> <pre><code>private void frmFavorites_Load(object sender, EventArgs e) { System.Xml.XmlDocument loadDoc = new System.Xml.XmlDocument(); loadDoc.Load(Application.StartupPath + "\\Favorites.xml"); foreach (System.Xml.XmlNode favNode in loadDoc.SelectNodes("/Favorites/Item")) { listViewFavs.Items.Add(favNode.Attributes["url"].InnerText); } } </code></pre> <p>When the form is closed again, it'll overwrite the xml-file and save all remaining items in the xml-file</p> <pre><code>private void frmFavorites_FormClosing(object sender, FormClosingEventArgs e) { System.Xml.XmlTextWriter writer = new System.Xml.XmlTextWriter(Application.StartupPath + "\\Favorites.xml", null); writer.WriteStartElement("Favorites"); for (int i = 0 ; i < listViewFavs.Items.Count ; i++) { writer.WriteStartElement("Item"); writer.WriteAttributeString("url", listViewFavs.Items[i].Text); writer.WriteEndElement(); } writer.WriteEndElement(); writer.Close(); } </code></pre> <p>To add and delete a bookmark, I'm using this code:</p> <pre><code>private void btnAddFav_Click(object sender, EventArgs e) { ListViewItem item = new ListViewItem(txtURL.Text); listViewFavs.Items.Add(txtURL.Text); } private void btnDelFav_Click(object sender, EventArgs e) { try { listViewFavs.Items.RemoveAt(listViewFavs.SelectedIndices[0]); } catch { MessageBox.Show("Je moet een item selecteren", "Geen item geselecteerd", MessageBoxButtons.OK, MessageBoxIcon.Warning); } } </code></pre> <hr> <p>Now, my problem:<br> I'd like to give my users the ability to double click on an item so they can navigate to their saved fav. At least, that's what SHOULD happen.<br> For so far, I've tried some codes and ended up with this:</p> <pre><code>private void listViewFavs_DoubleClick(object sender, EventArgs e) { try { FrmMain Main = new FrmMain(); Main.navigate(listViewFavs.SelectedItems[0].Text); } catch { MessageBox.Show("Je moet een item selecteren", "Geen item geselecteerd", MessageBoxButtons.OK, MessageBoxIcon.Warning); } } </code></pre> <p>frmMain is my browser and navigate is a public method that I use to check the URL's and to navigate.</p> <p>To navigate, I use this code:</p> <pre><code>public void navigate(String URL) { if (String.IsNullOrEmpty(URL) || URL.Equals("about:blank")) { GetActiveBrowser().DocumentText = Properties.Resources.FirstTime; // this is a HTML-doc you also see when you open the browser for the 1st time txtURL.Text = "about:blank"; return; } else if (!URL.StartsWith("http://") && !URL.StartsWith("https://") && !URL.StartsWith("file://") && !URL.StartsWith("ftp://")) URL = "http://" + URL; try { GetActiveTab().Text = "... Loading ..."; this.Icon = Properties.Resources.loading1; GetActiveBrowser().Navigate(new Uri(URL)); } catch (System.UriFormatException) { MessageBox.Show("'" + URL + "' is geen geldige URL", "Ongeldige URL", MessageBoxButtons.OK, MessageBoxIcon.Error); } } // go to URL </code></pre> <p>As you can see, I use a GetActiveTab() and GetActiveBrowser:</p> <pre><code>private WebBrowser GetActiveBrowser() { return (WebBrowser)tabs.SelectedTab.Controls[0]; } private TabPage GetActiveTab() { return tabs.SelectedTab; } </code></pre> <p>What actually happens:<br> I double-click on the item<br> Nothing happens -.- No navigation, no error, no nothing</p> <p>Does anyone have an idea to fix this problem?<br> I appreciate any help given.</p>
