Hi,

Try using

b.GetType()

instead of

b.getType().GetType().

The latter returns the type of the ActiveItem enumeration, which does not have a Style property. The former returns the type of the Box class.

It seems VB.NET is case insensitive and hides the "Object.GetType' method when there is a "getType" defined in a class. Try the following

       Dim obj As Object
       obj = b
       Dim t As System.Type = obj.GetType()

Hi,

Probably type conversion does not work when setting a value using reflection. Try passing some value from the BoxStyle enumeration instead of "3".

Stoyan, the next problem:

It's all now dynamicly but the value:

[code] Dim mi As MethodInfo = fc.GetType.GetMethod("CreateBox")
       Dim args() As Object = {10, 10, 90, 40}
       obj = mi.Invoke(fc, args)

       Dim t As Type = obj.GetType()
       Dim p As System.Reflection.PropertyInfo
       p = t.GetProperty("Style")
       Const mystyle As MindFusion.WebChart.BoxStyle = 3
       p.SetValue(obj, mystyle, Nothing)[/code]

If I try to set the mystyle dynamicly, I get a Null-Reference-Exception.

My code for that try:

[code]Dim str_class As String = "MindFusion.WebChart.BoxStyle"
       Dim str_value As String = "2"
       Dim theType As Type = Type.GetType(str_class)
       Dim o As Object = (CType(str_value, IConvertible)).ToType(theType, System.Globalization.CultureInfo.InvariantCulture)
       Dim b As Box = fc.CreateBox(10, 10, 100, 50)
       b.Style = o[/code]


But If I try that with a standard .net class e.g. "System.Int32" it works without any problems.
Here an example where I create an Int32 with the value 47:

[code]Dim str_class As String = "System.Int32"
Dim str_value As String = "47"
Dim theType As Type = Type.GetType(str_class)
Dim o As Object = (CType(str_value, IConvertible)).ToType(theType, System.Globalization.CultureInfo.InvariantCulture)
[/code]


thanks for your help in advance,

best regards, Daniel.
