Tengo un Problema. por favor, ¿Puede alguien ayudarme?
He decompilado un programa en .Net y sólo quiero que funcione estas 2 lineas en el form_load.
ucVEarth1.HTMLLocation = "C:\?" + rec_path.Text + "VirtualEarth.html?"
xtraTabControl1.SelectedTabPageIndex = &HB
He intentado hacerlo pero siempre borro mas de lo necesario y me da error.
El cambio quiero realizarlo en el EXE, es decir, con un editor Hexadecimal cambiar los valores.
Este es el codigo VB .Net:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim flag1 As Boolean = False
Dim s1 As String = System.String.Empty
Dim flag2 As Boolean = Not license.ValidateLicenseAtStartup(System.String.Empty, ByRef flag1, ByRef s1)
If Not flag2 Then
GoTo label_0
End If
DisplayLicenseForm()
Close()
Try
Dim textReader1 As System.IO.TextReader = New System.IO.StreamReader("C:\?" + rec_path.Text + "monitor.XML?")
Dim i1 As Integer = 2
Dim sArr1 As String() = New string(i1) {}
Dim i2 As Integer = 1
While flag2
sArr1(i2) = textReader1.ReadLine()
i2 = i2 + 1
flag2 = i2 < i1
End While
textReader1.Close()
flag2 = (sArr1(1)) Is Nothing
If flag2 Then
GoTo label_0
End If
comboBoxEdit1.Text = sArr1(1)
Try
ucVEarth1.HTMLLocation = "C:\?" + rec_path.Text + "VirtualEarth.html?"
Catch
End Try
Catch
System.Windows.Forms.MessageBox.Show("Problem reading Monitor Number?", "Contact support@simtouch.eu?", System.Windows.Forms.MessageBoxButtons.OK, System.Windows.Forms.MessageBoxIcon.Hand)
End Try
xtraTabControl1.SelectedTabPageIndex = &HB
End Sub

Podrias poner un salto incondicional (jmp) a las instrucciones para asi ejecutar sólo lo que quieres.
Seria algo asi:
IL_0000 2B AC br.s IL_00ae
-- aqui va el codigo original
Creo que el valor AC es correcto (172 bytes) pero verifícalo por las dudas.
No he probado este código, pero es una idea... :P
Saludos!
Perfecto!!!!!
Me diste la Idea!!!!, con el salto voy directamente a donde quiero :)
Muchísimas gracias.
