How to cast integer values as an array of enum values?


Hello all!

I'm working with VS2010 Beta2, ASP.NET and Dynamic Data. I'm using VB but will certainly be happy to receive a C# example if necessary. Laughing

I used a few of Steve's examples (Writing Attributes and Extension Methods for Dynamic Data and Dynamic Data - Hiding Columns in selected PageTemplates) to create a custom property attribute to be applied to a dynamic data column and want it to accept an array of enum values (each value will represent a dynamic data page template where this column should not be displayed).  My new attribute works fine when I hardcode it like this, meaning the HideColumnIn attribute is properly populated with the array of enum values:

<HideColumnIn(PageTemplate.List, PageTemplate.Edit)> _
Public Property My_DD_Column As Object


However, I want to store the values to be used for the HideColumnIn in the DB as integer values that correspond to the

Unity - Inject array

   this.validators = validators;

...I call the following but the array is empty...


Any ideas?

Class which contains an array of objects of type "Class2"



1  Partial Class _Default

5    theClass.ReSize(0)

Converting a byte array to a gif


Hi there,

I am currently in the process of trying to convert a byte array into a gif format. So far I have done this:

                        byte[] gif = Convert.FromBase64String(myByteArray);
                        MemoryStream ms = new MemoryStream(gif);
                        Bitmap image = new Bitmap(ms);
                        string pathToSave = Server.MapPath("~/_temp/");
                        iconUrl = string.Format("{0}/{1}.gif", pathToSave, fileName);

When this code block executes, I get the following error:

A generic error occurred in GDI+.

I have made sure that I have the correct permissions for the _temp folder, but I am not sure if I am trying to convert "bad bytes". Could someone perhaps shed some light on this error?
