VBA / Excel - " __doPostBack "

[Estevam Guilherme]

I'm trying to submit a form on a old asp classic page.

Here some script:

[ ******** type="text/javascript">
	//<=!=[=C=D=A=T=A=[
	var theForm = document.forms['aspnetForm'];
	if (!theForm) {
	theForm = document.aspnetForm;
	}
	function __doPostBack(eventTarget, eventArgument) {
	if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
	theForm.__EVENTTARGET.value = eventTarget;
	theForm.__EVENTARGUMENT.value = eventArgument;
	theForm.submit();
	}
	}
	//]=]=>
	*********>

<tbody>
</tbody>

]

Using Fiddler and navegating manually I got this:

And when I navegates using my code:

<dim sformlogin="" as="" string

sFormParameters = Join(Array( _
"__EVENTTARGET=", _
"__EVENTARGUMENT=", _
"__VIEWSTATE=", _
"__EVENTVALIDATION=", _
"ctl00$ContentPlaceHolder1$acc_Calendario1$myCalendario1$ctl22=17", _
"ctl00$ContentPlaceHolder1$acc_Calendario1$HiddenField1=", _
"__VIEWSTATEGENERATOR=C2EE9ABB", _
"__VIEWSTATEENCRYPTED"), "&")

Call IE.document.parentWindow.execScript("javascript: __doPostBack('sFormParameters')", "JavaScript")>

I have this: But it's not working.

How can set the parameters to get this working</dim>
