    Exclamation Passing info to website not working/waiting for it to be loaded

    I was hoping there might be someone out there that could help me out.
    The below code launches internet explorer and goes to the correct website, but won't pass info once loaded, or is passing it before it gets loaded (Done)

    Private mProcess As Process (Global)

    following is inside a sub:

    Dim myProcess As Process = New Process
    myProcess.StartInfo.FileName = "iexplore"
    myProcess.StartInfo.Arguments = ""
    myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Normal
    myProcess.EnableRaisingEvents = True

    Me.LaunchedProcess = myProcess
    If myProcess.Responding Then
    SendKeys.SendWait("text goes here")
    End If

    Private Property LaunchedProcess() As Process
    Return mProcess
    End Get
    Set(ByVal Value As Process)
    mProcess = Value
    End Set
    End Property

    Basically, what I am wanting to do, is Start the default brower with the "http" address and once it gets loaded, be able to pass it info...

    any help on getting it to pass the data, after the site has loaded, or a way to set the FileName to whatever that persons default browser is, would be greatly appreciated!!

    No, still not working. I edited out the issues that I fixed. Still have problems launching default browser by just using the http, and also being able to wait until website is loaded before passing it info.

    Why not use the Webbrowser control, hosted in your program's form, for this?

    There is a DocumentCompleted() event for the Webbrowser control. You would place the code that passes the information in that event.

    And you wouldn't have to worry about which browser the client is using!

    I am using Windows Forms in VB.

    I looked around for the WebBrowser stuff, but could only find info if I was using Web this something that can be done in Windows forms, if so, is there a link you can give me that will point me in the right direction.

    Thanks in advance.
