.
private void SubmitForm(String formName)
{
HtmlElementCollection elems = null;
HtmlElement elem = null;
if (webBrowser1.Document != null)
{
HtmlDocument doc = webBrowser1.Document;
elems = doc.All.GetElementsByName(formName);
if (elems != null && elems.Count > 0)
{
elem = elems[0];
if (elem.TagName.Equals("FORM"))
{
elem.InvokeMember("Submit");
}
}
}
}
Private Sub SubmitForm(ByVal FormName As String)
Dim Elems As HtmlElementCollection
Dim Elem As HtmlElement
If (WebBrowser1.Document IsNot Nothing) Then
With WebBrowser1.Document
Elems = .All.GetElementsByName(FormName)
If (Not Elems Is Nothing And Elems.Count > 0) Then
Elem = Elems(0)
If (Elem.TagName.Equals("FORM")) Then
Elem.InvokeMember("Submit")
End If
End If
