access to a property via string ?

[aschenk]

Hello Group,
is it possible to read/write a property value if the property-name is
in a string var ?

I know, this code don't work !!!:

Public Sub Change_Property(ByVal cn As Control, ByVal strProp As
String, ByVal Value As VariantType)

cn.<strProp> = value

End Sub

thanks, a.schenk

You can do it via reflection e.g.

cn.GetType().GetProperty("propName").SetValue(cn, newValue, Nothing)

If your property is non public you'll need to use the overload of
GetProperty which accepts a combination of BindingFlags

Try this:

Dim pi As System.Reflection.PropertyInfo
pi = cn.GetType().GetProperty(strProp,
BindingFlags.Public Or BindingFlags.NonPublic Or
BindingFlags.Static Or BindingFlags.Instance)
pi.SetValue(cn, Value, Nothing)
