Hi there, I would like to know how to click submit button on the HTML form in a webbrowser control.

HTML FORM:

<form method="POST" action="login.php">
					<table border="0" cellpadding="4" cellspacing="1" class="w12">
						<tr>
							<td>Login:</td>
							<td>
								<input type="text" name="username" class="b12">
							</td>
						</tr>
						<tr>
							<td>Password:</td>
							<td>
								<input type="password" name="password" class="b12">
							</td>
						</tr>
						<tr>
							<td colspan="2" align="right">
								<input type="submit" value="Login">
							</td>
						</tr>
					</table>
				</form>

Open in new window


PS: I have no access to the page, so I cannot change the source code, it has to work with the one above.

Thanks

You should be able to find the element by it's type and then use InvokeMember for the click:
For Each b As HtmlElement In WebBrowser1.Document.GetElementsByTagName("input")
    If b.GetAttribute("type") = "submit" Then
        b.InvokeMember("click")
    End If
Next

Open in new window


Note that if there are multiple forms with more than one submit, this would cause problems, in which case you can use a similar trick on the form itself (this is probably the better solution):

For Each b As HtmlElement In WebBrowser1.Document.GetElementsByTagName("form")
    If b.GetAttribute("action") = "login.php" Then
        b.InvokeMember("submit")
    End If
Next
