Loading GeckoWebBrowser Exceptions
- by Mostafa Mahdieh
I get a strange exception when a window containing a GeckoWebBrowser is loaded.
This is the exception message:
An unhandled exception of type System.Runtime.InteropServices.COMException occurred in Skybound.Gecko.dll Additional information: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
This is the windows code:
public partial class AddContents : Form
{
String path;
public AddContents(String path)
{
this.path = path;
InitializeComponent();
}
private void exitToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Close();
}
private void AddContents_Load(object sender, EventArgs e)
{
geckoWebBrowser1.Navigate(path);
}
private int selId = 1;
private bool updateMode = false;
private void timer1_Tick(object sender, EventArgs e)
{
if (updateMode)
update();
}
private void geckoWebBrowser1_DocumentCompleted(object sender, EventArgs e)
{
timer1.Enabled = true;
updateMode = true;
}
private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
geckoWebBrowser1.Navigate("javascript:scrollToBookmark(" + treeView1.SelectedNode.Tag + ")");
TreeNode selected = treeView1.SelectedNode;
TreeNode prev = selected.PrevNode;
TreeNode next = selected.PrevNode;
if (prev == null)
upButton.Enabled = false;
if (next == null)
downButton.Enabled = false;
}
private void update()
{
geckoWebBrowser1.Navigate("javascript:updateSelText()");
GeckoElement el = geckoWebBrowser1.Document.GetElementById("sel_result_991231");
if (el != null) {
textBox1.Text = el.InnerHtml;
addButton.Enabled = !textBox1.Text.Trim().Equals(String.Empty);
}
}
private void textBox1_Enter(object sender, EventArgs e)
{
updateMode = false;
}
private void geckoWebBrowser1_DomMouseDown(object sender, GeckoDomMouseEventArgs e)
{
updateMode = true;
update();
}
private void geckoWebBrowser1_DomMouseUp(object sender, GeckoDomMouseEventArgs e)
{

}

TreeNode t = new TreeNode(textBox1.Text);

}
}
