Question:

I need to know how to fill in form on webpage I need to log into the following Yahoo login page:
http://login.yahoo.com/config/login?.intl=us&.src=ygrp&.done=http://groups.yahoo.com%2Fgroup%2Fbrainm%2Fmessage%2F4001

Answer:

Hmmm. Ok, what you seem to be doing is trying to pre-stage a Browser window for a real user. And the window has some awful Javascript on it. I recommend OLE to control MSIE. For an example see...

And a user posted the following WinInet Example:

Here's some code from a Yahoo Groups application I've written.

AddExtender("WWINT34i.DLL")
host="login.yahoo.com"
mainurl="/config/login"
;Technically, you should ask for the username and password
login="myyahooid"
PW_password="mypassword"
;Format form data. First define the formdata variable as a null string
formdata=""
;Then add the required form fields one value=pair at a time.
;All these extra formdata are fields that are not required, but used on the Yahoo Groups login form
;formdata=iContentUrl(formdata,".src","ygrp")
;formdata=iContentUrl(formdata,".tries","1")
;formdata=iContentUrl(formdata,".last","")
;formdata=iContentUrl(formdata,"promo","")
;formdata=iContentUrl(formdata,".bypass","")
;formdata=iContentUrl(formdata,".partner","")
;formdata=iContentUrl(formdata,".v","0")
;formdata=iContentUrl(formdata,".emailCode","")
;formdata=iContentUrl(formdata,"hasMsgr","")
;formdata=iContentUrl(formdata,".chkP","Y")
;formdata=iContentUrl(formdata,".intl","us")
;formdata=iContentUrl(formdata,".done","http://groups.yahoo.com/mygroups/")
formdata=iContentUrl(formdata,"login",login)
formdata=iContentUrl(formdata,"passwd",PW_password)
;formdata=iContentUrl(formdata,".persistent","y")
formdata=iContentUrl(formdata,".save","Sign In")
tophandle=iBegin(0,"","")
connecthandle=iHostConnect(tophandle, host, @HTTPS, "", "")
datahandle=iHttpInit(connecthandle,"POST",mainurl,"", 0)
rslt = iHttpOpen(datahandle, 0, formdata, -1)
if rslt!=200
headers=iHttpHeaders(datahandle)
AskItemList("Login Result=%rslt%",headers,@tab,@unsorted,@single)
endif
xx=iReadDataBuf(datahandle,bufaddr,20000)
InvalidPwd = BinaryIndexEx(outbuf, 0, "Invalid Password", @FWDSCAN,0)
If InvalidPwd > 0 Then 
Message("Invalid Password","You entered the wrong password for this account. %@crlf%Please reenter your password on the
Preferences screen.")
FileClose(loghandle)
EndIf
DoesNotExist=BinaryIndexEx(outbuf, 0, "does not exist", @FWDSCAN,0)
If DoesNotExist > 0 Then
Message("The Yahoo ID does not exist","You entered a Yahoo ID that does not exist. %@crlf%Please reenter your Yahoo ID on the
Preferences screen.")
FileClose(loghandle)
EndIf
