I'm writing a vb.net client that will navigate a web site by populating the controls. One of the pages accepts both text box data AND requires a file to be uploaded.

It is a state judicial web site whihc allows electronic filing of documents. I am at a roadblock at the actual upload filing page. It has a multipart form (created via java scriptlets) containg several file controls and several other controls (text, check box). all wich need to be populated.

So I need to populate the text and check  boxes as well as upload the file. Ideas?

I have used a WebBrowser control to pull up the page, get references to the controls, fill in data, click buttons.

Hi Bob,

Are you refering to the old INET control or old web browser control or is  there anything new in .net that is available?

Can you provide an example of the code which will do this?

1) .NET version?

2) Yes, the WebBrowser is still a bigger player in the .NET arena.

3) It depends on the web page, as to whether you can interact with it using the WebBrowser control.

4) 2005 has the WebBrowser control as a managed control, but with 2003 you have to add an unmanaged COM control to the project.

Here is a previous question that should highlight what I mean with 2003:

Bob,

Sorry for the delay in getting back to you, I had another crisis to resolve. Thanks for the help, we are on the right track.

This is .NET 1.1.


I used the WebBroswer control only to discover that the FILE control is a READONLY object. However, I did some further searching and found that giving focus to the control and using the SENDKEYS.SEND method, I can bypass the READONLY nature of the control.

I created a class to do this and the code is as follows:

Public Class FCNET
    Public strErrorMsg As String = ""

    Public ReadOnly Property ErrMsg() As String
        Get
            Return strErrorMsg
        End Get
    End Property

    Public Function SetInputValueNET(ByRef vInPut As mshtml.HTMLInputElement, ByVal newValue As String) As Boolean
        vInPut.focus()
        Try
            System.Windows.Forms.SendKeys.Send(newValue)
            System.Windows.Forms.Application.DoEvents()
        Catch ex As Exception
            strErrorMsg = "SendKeys.Send error: " & ex.Message
            Return False
        End Try
        Return True
    End Function
End Class

Seems to do the trick....

Again thanks....

Lee
