VBA / Excel - " __doPostBack "

[Estevam Guilherme]

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

Here some script:

<tbody>
[TD="class: line-content"][ ******** type="text/javascript">[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"]//<=!=[=C=D=A=T=A=[[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"]var theForm = document.forms['aspnetForm'];[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"]if (!theForm) {[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"] theForm = document.aspnetForm;[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"]}[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"]function __doPostBack(eventTarget, eventArgument) {[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"] if (!theForm.onsubmit || (theForm.onsubmit() != false)) {[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"] theForm.__EVENTTARGET.value = eventTarget;[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"] theForm.__EVENTARGUMENT.value = eventArgument;[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"] theForm.submit();[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"] }[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"]}[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"]//]=]=>[/TD]

[TD="class: line-number"][/TD]
[TD="class: line-content"]*********>[/TD]

</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>
