Code:

// If there is only one button, you can do something like:

WebBrowser1.OleObject.Document.forms.item(0).elements.item(0).click;

// This will do a click on the first element of the first <FORM>, where an

// element is either <INPUT>, <SELECT> or <TEXTAREA>.

// If there is more than one button, you can do something like:

procedure TForm1.Button1Click(Sender: TObject);

var

ovElements: OleVariant; 

i: Integer; 

begin

ovElements := WebBrowser1.OleObject.Document.forms.item(0).elements; 

for i := 0 to (ovElements.Length - 1) do

   if (ovElements.item(i).tagName = 'INPUT') and

     (ovElements.item(i).type = 'SUBMIT') and

     (ovElements.item(i).Value = 'Recent Charges') then

     ovElements.item(i).Click;
