Hello all,
I am searching on the net for 2 days and I am reading a lot about Hooking and Injecting your own dll's into another process, but I don't get clear what technique is usefull for me. Let me explain what I want to accomplish.
I want to monitor a 3rd party application what actions a user takes, like he opened an options window and on the close button click I want to get the values he entered. Or he opened a process that takes a while (like processing a document).
I looked into some things, but can get a clear view on this.. Can someone helps me out?
Many thanks in advance,
Derck
(P.S. I don't find many vb.net samples on hooking or subclassing

Hi,
Thanks for your reply.. I already looked into this article, but I need a way to monitor 3rd party applications where I don't have any source from.. I am looking for a couple days now and I don't get a clear picture where to start. I know it's not simple, but I need to know what technique is useful for me..
Thanks in advance!

Plain and simple, you can't without in-depth knkowledge of the 3rd party app. There are two ways:
1.) Use DDE
2.) Get the Window Handle and use some API like we did in VB6 to subclass that windows' WndProc event into your own window.
I'll tell you now, since every window, including controls, have their own WndProc, you're not going to be able to write a "Global" handler for some app's events. Unless this 3rd party app is supplying an API (like Adobe or MS Word, Outlook for example), you can't do it.

Many thanks! I will look into the options you gave me..
What I need is
1) Detects a user close the options form (like windows messenger)
2) Capture and save the values he entered..
I am not making a global spy util (maybe it is), but I want to monitor an application like Crystal Reports what actions the user did and what data he saw... Maybe there are some other options?
Thanks!

Firstly you have to put a dataGrid inside your form, than paste the code below inside your Form1.vb page
here is the simple datagrid code:
-----------------------------------
Imports System.Data.SqlClient
Public Class Form1
Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
'Form overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub
'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer
'NOTE: The following procedure is required by the Windows Form Designer
'It can be modified using the Windows Form Designer.
'Do not modify it using the code editor.
Friend WithEvents Button1 As System.Windows.Forms.Button
Friend WithEvents DataGrid1 As System.Windows.Forms.DataGrid
Friend WithEvents UserControl11 As maskedTextBox.MaskeliTextBox
Friend WithEvents reportDocument1 As CrystalDecisions.CrystalReports.Engine.ReportDocument
<system.diagnostics.debuggerstepthrough()> Private Sub InitializeComponent()
Me.Button1 = New System.Windows.Forms.Button
Me.DataGrid1 = New System.Windows.Forms.DataGrid
Me.reportDocument1 = New CrystalDecisions.CrystalReports.Engine.ReportDocument
CType(Me.DataGrid1, System.ComponentModel.ISupportInitialize).BeginInit()
Me.SuspendLayout()
'
'Button1
'
Me.Button1.Location = New System.Drawing.Point(480, 48)
Me.Button1.Name = "Button1"
Me.Button1.TabIndex = 0
Me.Button1.Text = "Sorgula"
'
'DataGrid1
'
Me.DataGrid1.DataMember = ""
Me.DataGrid1.HeaderForeColor = System.Drawing.SystemColors.ControlText
Me.DataGrid1.Location = New System.Drawing.Point(24, 184)
Me.DataGrid1.Name = "DataGrid1"
Me.DataGrid1.Size = New System.Drawing.Size(648, 224)
Me.DataGrid1.TabIndex = 1
'
'reportDocument1
'
Me.reportDocument1.PrintOptions.PaperOrientation = CrystalDecisions.Shared.PaperOrientation.DefaultPaperOrientation
Me.reportDocument1.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.DefaultPaperSize
Me.reportDocument1.PrintOptions.PaperSource = CrystalDecisions.Shared.PaperSource.Upper
Me.reportDocument1.PrintOptions.PrinterDuplex = CrystalDecisions.Shared.PrinterDuplex.Default
'
'Form1
'
Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
Me.ClientSize = New System.Drawing.Size(704, 430)
Me.Controls.Add(Me.DataGrid1)
Me.Controls.Add(Me.Button1)
Me.Name = "Form1"
Me.Text = "Form1"
CType(Me.DataGrid1, System.ComponentModel.ISupportInitialize).EndInit()
Me.ResumeLayout(False)
End Sub
#End Region
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim conn As New SqlConnection("Server=.;Database=pubs;uid=sa;pwd=;")
conn.Open()
Dim comm As New SqlCommand("Select * From Employee")
Dim adp As SqlDataAdapter = New SqlDataAdapter(comm.CommandText, conn)
Dim ds As New DataSet
adp.Fill(ds)
DataGrid1.DataSource = ds
End Sub
End Class

<configuration>
<system.runtime.remoting>
<application>
<service>
<wellknown

Hi everybody
Does anyone know how can I design my report in landscape mode. I don't know how can I enlarge the margins of my Report.
Thanks in Advance

If you're using it inside the .NET IDE, [right-click --> choose designer --> Printer setup --> change to landscape].

hi to you all,
i need to search group of objects in an arraylist and the only reference i have is their IDs,
is there a fast way to search those objects?
iterating through the arraylist again and again would be quite slow...
thanks in advance,

thanks anyway!

how can i create a relationship beween scanner and a form in vb
|
|
|
|
|
Buy them both movie tickets, I guess.....
What do you want to do - get the form to always show what's on the scanner ? There's no way for the code to know that the contents of the scanner have changed. Do you have TWAIN drivers in VB.NET already ?

Hi, in vb6 in the code windows if i want to delete a single line of code at a time, I could press the shortcut key Ctrl + Y
But in vb.net this method is not working. Does anyone know how to delete a single line of code at a time by using shortcut key in vb.net?
