Hmm, this works for me:

Dim assemblyToLoad As [Assembly]
' Load assembly from file
assemblyToLoad =
[Assembly].LoadFrom("D:\Projects\ClassLibrary\bin\ClassLibra ry.dll")

' Find the assembly module
Dim assemblyModule As [Module] =
assemblyToLoad.GetModule("ClassLibrary.dll")
' Find the Module type.
Dim moduleType As Type = _
assemblyModule.GetType("ClassLibrary.Module1")

' Get the public Company constant
Dim PublicField As FieldInfo
PublicField = moduleType.GetField("Company")
MsgBox(PublicField.Name.ToString)
MsgBox(PublicField.GetValue(PublicField).ToString)

ThatŽs what iŽve tried but it ends up with an exception that the object
type cant be converted to the target type.
Displaying the name of the constant is no problem...

My code in the module:
Public Const Company As String = "TestCompany"

My code in the main application:
Dim PublicField As FieldInfo
PublicField = FormType.GetField("Company")
MsgBox(PublicField.Name.ToString) <- that works perfectly,
displaying "Company"
MsgBox(PublicField.GetValue(PublicField).ToString) <- no way :-(


Any idea?

Thanks,
Andy

This is one way:

fi.GetValue(fi).ToString

Feel free to use a conversion function instead of the ToString method,
depedning on the type of constant you have, i.e. CInt for and Integer
etc:

Dim x As Integer = CInt(fi.GetValue(fi))

No way, it doesn't want to work here...
Maybe you can send a copy of the main project and the library project to
andy.mail (AT) zwickau-net (DOT) de?

Or can I call a function from the module library, which throws the
variables i would like to have?

Thank you,
Andy

Enjoy the weekend.

CT,

thanks for your very quick answer.
Is it possible to include forms in assemblies so the assembly can be a
complete program which is called from the main application?

Can you recommend an assembly tutorial to me?
You'll find one here :-)
