Hi Expert,


I am the fan of VB My.Application.Log. When I create a new project, it
works but after some times My.Application.Log.WriteEntry nno longer
work. Exception is enclosed:

Well, it's suggesting that you've got illegal characters in a path
somewhere. Could you post the code you're using?

MsgBox

But
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) do
not.
Strange.

Jon,

I got it, I modified <Assembly: AssemblyVersion("4.0.*.*")> in
AssemblyInfo.vb, * is the reason for illegal path characters. Then the
question is how 4.0.*.* does not work? Oh I found that this is a bug:

' Version information for an assembly consists of the following four
values:
'
' Major Version
' Minor Version
' Build Number
' Revision
'
' You can specify all the values or you can default the Build and
Revision Numbers
' by using the '*' as shown below:
' <Assembly: AssemblyVersion("1.0.*")>

<Assembly: AssemblyVersion("4.0.*.*")>
<Assembly: AssemblyFileVersion("4.0.*.*")>
