How to rename sub main to function main

I made an console application with Visual Basic .net. Visual Basic will
automatically create the sub procedure main for you. I try to convert the
main procedure to a function.

During the compilation I will get an error message:

No accessible 'Main' method with an appropriate signature was found in
<application>.

I took a look at the following settings in Visual Basic dotnet:

Project, properties, common properties, general, start object

Here it's possible to define you startup project, but when I modify this
option, the startup object is automatically reset to Sub Main in stead of
Function Main.

Does someone know how to change this?

Thank in advance.

Kind regards,

Rody

Post the code you are using.
 
Hello, Rody:

The Main() method must have public access. If it is inside a class, it must also be shared:

\\\
module MyTestModule
public sub Main()
end sub
end module

class MyTestClass
public shared sub Main()
end sub
end class
///

Regards.

The problem is solved now.

The reason why it did work was because I did specify:

Function Main()
' Do something

Return <integer value>
End Function

in stead of

Function Main() as Integer
'Do something

Return <integer value>
End Function

As you can see I did not explicitly specify the returnvalue type from the
function.

Thanks for you help.

Kind regards,

Rody

Always do that! I would specify an access modifier explicitly too.

Herfried,

Having never used an access modifier in this situation myself,
which would you recommend and why?

'Public Sub Main'. If you don't specify a modifier, the sub will be
public too, but it's "good style" to always specify the modifier...

If Option Strict On was set, it should have flagged it as an error. Is
Option Strict On?
