Hepl! No accessible 'Main' method with an appropriate signature was found ...

[Paulers]

Hello vb.net experts :)

I am trying to program an app that resides in the system tray and I am
trying to put all my main code in sub Main(). I am getting this
errormessage at compile:

Performing main compilation...
vbc : error BC30737: No accessible 'Main' method with an appropriate
signature was found in

I have done some post searching that has mentioned setting the project
properties entry point to sub main() and I have tried that with no
luck. I have tried placing my sub just about everywhere with hopes that
the error would go away. Right now it resides right under the "Windows
Form Designer generated code" section. Here is my sub, any help is
greatly appreciated.

Public Sub Main(ByVal cmdArgs() As String)
Dim RegEntry = GetNzbDirFromReg()
Dim Verified = VerifyDir(RegEntry)

If Verified = False Then
MessageBox.Show("Can not locate your config. Please make
sure the application is installed. Exiting.", "Blah",
MessageBoxButtons.OK)
Application.Exit()
End If
' GetPaths()
If ComPath.Length < 1 Then
MenuItem16.Enabled = False
End If
If InComPath.Length < 1 Then
MenuItem17.Enabled = False
End If
foxCheck()
AddHandler t.Elapsed, AddressOf TimerFired
End Sub

Thank you for such a quick reply! I added the shared and I am now
getting more errors of a OOP nature.

Cannot refer to an instance member of a class from within a shared
method or shared member initializer without an explicit instance of the
class. I am searching for some posts regarding this topic but so far I
have not been able to get anything to work. here are some of my
functions it has a problem with.

Public Function SetNzbPath() As String
FolderBrowserDialog1.Description = "Please select the directory
containing SABnzbd.exe"
If FolderBrowserDialog1.ShowDialog() = DialogResult.OK Then
NZBfolder = FolderBrowserDialog1.SelectedPath
Return NZBfolder
End If
End Function

Public Function VerifyDir(ByVal NZBfolder) As Boolean
If Not System.IO.File.Exists(NZBfolder + "\SABnzbd.ini") Then
If Not System.IO.File.Exists(SetNzbPath() + "\SABnzbd.ini")
Then
Return False
Else
Return True
End If
End If
End Function

Public Function GetNzbDirFromReg() As String
Dim regKey As RegistryKey
regKey = Registry.LocalMachine.OpenSubKey("Software\Paulers
Software Works\", True)
Return regKey.GetValue("NZBfolder")
End Function

Cut the code which is currently placed in your 'Sub Main' and add it to the
form's constructor right after the call to 'InitializeComponent'. Then
either remove 'Sub Main' completely and set the form as startup object or
add the code below to 'Sub Main':

\\\
Application.Run(New MainForm())
///

Thanks so much for all your help. that seemed to do the trick however
there is one small issue. I am doing an Application.Exit() and the
program skips passed it like it was not there. I also tried a me.Close
and the same thing happened. Are there any other ways to terminate the
application?

'Me.Close()' should be sufficient. 'Application.ExitThread' should work
too. I suggest to set a breakpoint on the call to 'Me.Close()' and check if
it gets called. If this doesn't solve the problem, you could post relevant
parts of the source code.

I set a breakpoint on me.close and the application did not break. Could
it be because I am trying to exit the application previous to the form
designer completing its work? Here is the code. Thanks!

#Region " Windows Form Designer generated code "

Public Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
Dim regKey As RegistryKey
Dim ChosenPath As String
NotifyIcon1.Text = "WinSABnzb"
regKey = Registry.LocalMachine.OpenSubKey("Software\Paulers
Software Works\", True)
If System.IO.File.Exists((Trim(regKey.GetValue("NZBfo lder"))) +
"\SABnzbd.ini") = False Then
FolderBrowserDialog1.Description = "Please select the
directory containing SABnzbd.exe"
If FolderBrowserDialog1.ShowDialog() = DialogResult.OK Then
ChosenPath = FolderBrowserDialog1.SelectedPath
End If
If System.IO.File.Exists(Trim(ChosenPath) & "\SABnzbd.ini")
= False Then
MessageBox.Show("WinSABnzb can not locate your
SABnzbd.ini. Please make sure SABnzbd is installedin the directory
specified. Exiting.", "About WinSABnzb", MessageBoxButtons.OK)
Application.Exit()
Me.Close()
Application.ExitThread()
Else
NZBfolder = Trim(ChosenPath)
regKey.SetValue("NZBfolder", NZBfolder)
End If

NZBfolder = Trim(regKey.GetValue("NZBfolder"))
regKey.SetValue("NZBfolder", NZBfolder)

I suggest to decouple startup code from the form code by moving it to 'Sub
Main':

\\\
If <did some startup stuff successfully> Then
Application.Run(New MainForm())
End If
///

You won't need to close any forms and the application will exit
automatically if startup was not successful.

hi again Herfried,

I am in the process of moving my checks to main() and one thing I
noticed is the functions that I called previously do not work anymore.
they appear highlighted with the explicit error message that I
mentioned in previous posts "Cannot refer to an instance member of a
class from within a shared method or shared member initializer without
an explicit instance of the class." I also noticed that the variables I
had declared globaly (at the very top) are no longer visable. Can you
show me an example of how I would create an explicit instance of a
function? Thanks :)
