Why can't you increment ushort or byte variables (+1)??

Posted By:      Posted Date: September 25, 2010    Points: 0   Category :ASP.Net

According to the C# built-in types table at http://msdn.microsoft.com/en-us/library/ya5y69ds.aspx,

the ushort is a 16-bit unsigned integer.  The byte is an 8-bit unsigned integer.

So when I declare:

public byte x;

ushort y;

Neither of those, I can not do the following:

x = x+1;


i get an error: "Cannot implicitly convert type "int" to "ushort" or to "byte".

Why is this?  They are both integer-grade data types?  I don't want to use the "int" type because that is a 32-bit signed integer, requiring more memory than I need.

Temporary tables in SQL Server vs. table variables

When writing T-SQL code, you often need a table in which to store data temporarily when it comes time to execute that code.

Defining session variables...



This is a pretty basic question.

I have some code where I need to define a session variable  however it's coming back as Nothing when the code is executed. Here's the code:

' Default Currency

REQCURR = Request.Querystring("p_DCURR")
'If not explicitly specified, try to get it from session

If (REQCURR = "") Then

     If (Session("REQCURR") <> "") Then
          REQCURR = Session("REQCURR")

          'Here is the session variable I'm trying to define:
          Session("REQCAD") = 0
          REQCURR = ""
     End If

End If


So, for some reason that Session("REQCAD") = 0 has no value instead of having a value of 0.

Any thoughts?


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?
