Copying content to a DOM Textarea element in c#

[davidc2p]

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.

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?
