不定时上论坛解答问题。
定时部分用Timmer就不说了，发送部分
1：用异步下载方式
Dim oADL As AsyncDownload
oADL.Download URL, , , "Post", , "UserName=uname&PWD=password"
2：用WebBrowser控件
'赋值
WebBrowser1.Document.All.UserName.Value = "uname"
WebBrowser1.Document.All.PWD.Value = "password"
'提交
Private Sub cmd点击注册帐号提交_Click()
On Error Resume Next
'对于没有Name的没找到好方法，只能用这种笨方法，你有如好的方法可告诉我：）
Dim i As Integer
Dim j As Integer
For i = 0 To Val(WebBrowser1.Document.All.length - 1)
If WebBrowser1.Document.All.Item(i).Name <> "login" Then
Else
j = i
Exit For
End If
Next
WebBrowser1.Document.All.Item(i).Click
End Sub

我写了一个定时向所有IE窗口写时间的程序，LZ可在此基础上进一步发挥。
类模块：clsIE.cls
Option Explicit

Public Event NewWindow(Cancel As Boolean)
Public Event Quit()
Public Event BeforeNavigate(ByVal pDisp As Object, URL As Variant, Flags As Variant, TargetFrameName As Variant, PostData As Variant, Headers As Variant, Cancel As Boolean)
Public Event DocumentComplete(ByVal pDisp As Object, URL As Variant)

Public WithEvents IE As InternetExplorer

Dim WithEvents MyTimer As Timer
Dim m_lCookie As Long

Private Sub Class_Terminate()
On Error Resume Next
MyTimer.Enabled = False
Form1.Controls.Remove ("VB.Timer" & CStr(lCookie))
Set IE = Nothing
End Sub

Public Property Let lCookie(ByVal lNewCookie As Long)
m_lCookie = lNewCookie
Set MyTimer = Form1.Controls.Add("VB.Timer", "MyTimer" & CStr(m_lCookie))
MyTimer.Interval = 1000
MyTimer.Enabled = True
End Property

Public Property Get lCookie() As Long
lCookie = m_lCookie
End Property

Public Sub IE_BeforeNavigate2(ByVal pDisp As Object, URL As Variant, Flags As Variant, TargetFrameName As Variant, PostData As Variant, Headers As Variant, Cancel As Boolean)
RaiseEvent BeforeNavigate(pDisp, URL, Flags, TargetFrameName, PostData, Headers, Cancel)
MyTimer.Enabled = False
End Sub

Public Sub IE_DocumentComplete(ByVal pDisp As Object, URL As Variant)
RaiseEvent DocumentComplete(pDisp, URL)
If IE.Busy = False Then
MyTimer.Enabled = True
End If
End Sub

Public Sub IE_NewWindow2(ppDisp As Object, Cancel As Boolean)
Dim m_Cancel As Boolean
RaiseEvent NewWindow(m_Cancel)
cancle = m_Cancel
End Sub

Public Sub IE_OnQuit()
RaiseEvent Quit
End Sub

Private Sub MyTimer_Timer()
Dim i As Integer
Dim Body As Object
Dim MyElement As Object

On Error Resume Next
Set Body = IE.document.Body
Set MyElement = IE.document.getElementById("MyTimeLable")
If TypeName(MyElement) <> "Nothing" Then
MyElement.innerHTML = "当前时间：" & Time() & ""
ElseIf TypeName(Body) <> "Nothing" Then
Body.innerHTML = "当前时间：" & Time() & "" & Body.innerHTML
End If
Err.Clear
End Sub
窗口模块：Form1.frm
Option Explicit

Dim WithEvents Shl As ShellWindows

Set IEMonitor(IE_Count).IE = Shl.Item(i)
IEMonitor(IE_Count).lCookie = i
IE_Count = IE_Count + 1
End If
Next
End Sub

Private Sub Form_Unload(Cancel As Integer)
Dim i As Integer
For i = 0 To IE_Count - 1
Set IEMonitor(i) = Nothing
Next
Set Shl = Nothing
End Sub

Private Sub Shl_WindowRegistered(ByVal lCookie As Long)

ReDim Preserve IEMonitor(IE_Count)

Set IEMonitor(IE_Count).IE = Shl.Item(Shl.Count - 1)
IEMonitor(IE_Count).lCookie = lCookie
IE_Count = IE_Count + 1
End If
End Sub
