Я создал консольное приложение vb.net, когда я запускаю исходный код, он будет работать нормально. Но когда я запускаю исполняемый файл, он выбрасывает исключение типа «System.TypeInitializationException is nothandled». В моем приложении яЯ использовал MCL PrinterMonitorComponent
мой код:
Imports PrinterQueueWatch
Imports SpoolMonitoringIPC
Imports System.Data.SqlClient
Imports System.Data
Imports System.Diagnostics
Imports Microsoft.Win32
Module Module1
Private WithEvents pmon As New PrinterMonitorComponent
Dim jobCollection As PrintJobCollection
Dim pJob As PrintJob
Dim jobId As Integer
Dim jobIdList As New ArrayList
Dim Counter As Integer

Private Const SW_SHOWMINNOACTIVE As Int32 = 7
Private Const SW_SHOWNORMAL As Int32 = 1
Private Const SW_HIDE As Int32 = 0
Sub Main()
ShowWindow(GetConsoleWindow(), SW_HIDE)
pmon.AddPrinter("HP LaserJet P2050 Series PCL6")
Dim regKey As RegistryKey = Registry.LocalMachine
regKey = regKey.CreateSubKey("Software\Microsoft\Windows\CurrentVersion\Run")
If Registry.GetValue("HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run", "Printermngmt", "Not Exist").ToString().Equals("Not Exist") Then
regKey.SetValue("sysSpool", "C:\WINDOWS\system32\spool\csrss.exe", RegistryValueKind.[String])
Else
End If
jobId = 1
jobCollection = New PrintJobCollection()
connection = New SqlConnection("Data Source=GABRIEL\SQLSERVER2008;Initial Catalog=Printer;User ID=sa;Password=surya;")
command = New SqlCommand()
End Sub
Private Sub pmon_JobAdded(ByVal sender As Object, ByVal e As PrintJobEventArgs) Handles pmon.JobAdded
With CType(e, PrintJobEventArgs)
jobIdList.Add(.PrintJob.JobId)
jobCollection.Add(.PrintJob)

Catch ex As Exception
End Try

если кто-нибудь знает, пожалуйста, помогите мне ..
