Newbee - Project with single module.

Guest

Hi Guys,
I writing a project with just one module in it (the reason for this is to
debug code before it becomes a service) and am getting an error which I do
not understand:

No accessible 'Main' method with an appropriate signature was found in
'FTP_Log_Watcher'.

I have set the properties of FTP_Log_Watcher to Startup with 'Sub Main'.

I used to use VB6 about 3-4 years ago, but only as an amatuer. I have only
been using Visual Basic for 2 months - please go easy if it is obvious to you.

Below is the module:

Imports System.IO
Imports System.Data

Public Class EDI_Watcher

Dim gSQLCommandBuilder As System.Data.SqlClient.SqlCommandBuilder
Dim gDataAdapter As System.Data.SqlClient.SqlDataAdapter
Dim gCurrentExample As Integer

Private sDatabase As String
Private sServer As String
Private sUserID As String
Private sPassword As String
Private sConnectionString As String
Private cnn As System.Data.SqlClient.SqlConnection
Private cmd As System.Data.SqlClient.SqlCommand

Public WriteOnly Property Database()
Set(ByVal Value)
sDatabase = Value
End Set
End Property

Public WriteOnly Property Server()
Set(ByVal Value)
sServer = Value
End Set
End Property

Public WriteOnly Property UserID()
Set(ByVal Value)
sUserID = Value
End Set
End Property

Public WriteOnly Property Password()
Set(ByVal Value)
sPassword = Value
End Set
End Property

Public Sub Main(ByVal args() As String)
Call Watcher()
End Sub

Public Sub Watcher()

Const ForReading = 1, ForWriting = 2

Dim MyFileObject
Dim ScriptTimeout
Dim DebugFlag As Boolean
Dim MyFolder
Dim SubFolder
Dim Folder
Dim Date_Comps
Dim Log_Dir

Dim CurrentFolder
Dim FileColl

Dim objFile

Dim strDbInfo As String

Dim Source_Dir
Dim NI_FTP_Dir
Dim Tradanet_Dir
Dim RASCAL_Dir

MyFileObject = CreateObject("Scripting.FileSystemObject")

ScriptTimeout = 9999


'##### DEBUGGING SWITCH #####
DebugFlag =
System.Configuration.ConfigurationSettings.AppSettings("Debug")
Dim strDebug As String
If DebugFlag = True Then strDebug = "Debug_"


'###########################

'################## Change Path HERE ##########################

'#### Path is read from app.config file. ####
Source_Dir =
System.Configuration.ConfigurationSettings.AppSettings(strDebug &
"SourcePath")


'################## Change Path HERE ##########################

MyFolder = MyFileObject.GetFolder(Source_Dir)
Folder = MyFileObject.getfolder(MyFolder)


FileColl = CurrentFolder.Files

Dim dFolder As DirectoryInfo = New DirectoryInfo(Folder.path)
Dim fFileArray() As FileInfo = dFolder.GetFiles
' 'FILEARRAY' NOW HOLDS ALL THE FILES IN THE SELECTED FOLDER

Dim fFile As FileInfo

' LOOP THROUGH ARRAY, LISTING ALL FILES IN LISTVIEW
For Each fFile In fFileArray

'Pass filename, filedate, filelastmodified and filesize to SP
'to check if file has changed since last program execution.

Try taking the parameter list out of the main signature - VB doesn't use
that. For capturing the command line arguments use
Microsoft.VisualBasic.Command() and parse the resulting string.

John,

We do not know what version you are using and the way you change this is
different.

However you have to set in your Project Properties in solution explorer your
Startup point.

Mostly is this Sub Main, however in a form that is integrated and you start
with Form.
Probably have you removed that Form from your class and do you have to
change the startup point.

This is always difficult to describe, moreover because it is in the two
versions different. In 2005 you have to change the form for a concole
application to let it go.

I hope this helps,

Cor

1. VB.NEt 2003.
2. Project Properties have been set.
3. No Forms - Module Only Project!
4. Again No Forms!

All but the first one was covered in my original posting - Did u read it

I did not see it in this thread, do you mean that you are multiple times
putting this in this newsgroup?
Than put your questions about those in the original thread, than we can see
the answers from others, in this way it takes to much time.
