Copying content to a DOM Textarea element in c#

Greeting,

I sometimes have a problem with the code below. Sometimes it returns a strange error depending on the content I want to pass to the Textarea element of a webpage.

Code:

---

HtmlDocument DOC = this.webBrowser1.Document; 
foreach (ListViewItem lvi in lvFieldsCopying.Items) 
{ 
    if (lvi.SubItems[2].Text != "") 
    { 
        HtmlElementCollection oHtmlElements = DOC.GetElementsByTagName("textarea"); 
        foreach (HtmlElement textarea in oHtmlElements) 
        { 
            if (textarea.Name == lvi.SubItems[2].Text) 
            { 
                //MessageBox.Show(lvi.SubItems[1].Text); 
                try { 
                    textarea.InnerHtml = lvi.SubItems[1].Text.ToString(); 
                } 
                catch (Exception exp) { 
                    MessageBox.Show("Could not copy your field to the site field: " + exp.Message); 
                } 
            } 
        } 
    } 
}

---

Sometimes, depending on the content of the SubItem, exp.Message is "Exception from HRESULT: 0x800A0259".

Did someone run into this already?

Hi, did you solve this problem?

I also have the same problem in my program, a little strange.

Can you give some suggestion? Thanks.
