IL DynamicMethod question - Boxing

Hey all I have dynamic method that get a type passed in. how do I use that param to box the object. So...

<br />
DynamicMethod dynamnicGet = new DynamicMethod("DynamicGet", typeof(object), new Type[] { typeof(object), typeof(Type) }, typeof(object));<br />
ILGenerator il = dynamnicGet.GetILGenerator();<br />
il.Emit(OpCodes.Ldarg_0); // load the source object onto the stack<br />
il.Emit(OpCodes.Callvirt, methodInfo); // call the method<br />
il.Emit(OpCodes.Ldarg_1); // load the type onto the stack<br />
// Now I want to box it the return type to the param type<br />
// Can not use il.Emit(OpCodes.Box, ) because I do not have the type in c#, it is in the IL<br />
il.Emit(OpCodes.Ret); // return<br />

Hope that makes sense. Any ideas anyone?

Thanks,
Luke

What's a PivotTable?

As it turns out, just a couple weeks ago I found I had the need to take a DataTable and pivot it, so I wrote a method to do it.

The shortcoming (and probably why it's not built-in) is that unless all the original columns hold the same datatype, you have to make the resultant columns hold object (or determine some other common ancestor).

At the time I was thinking of writing an article about it, maybe I should.

Ok simple problem

This is a simple problem that I cannot believe that I can't solve!!

I have a C# ASP.NET site.... Easy! In my HTML/ASP I have a datagrid declared and one of the columns in my datagrid pulls dates from the database (through a data set) and displays them on the page. My dates come up looking like this:

21/02/2006 12:00:00 AM

I want them to look like this:

21/02/06

I've tried to do this to the header DataFormatString="{0:dd/MM/yy}" but that doesn't work!

Any suggestions to this problem would be awesomely appreciated!!

Cheers everyone,

Michael!!

Why can't you query that format from the database itself?

set dateformat 'dmy'

select convert( varchar,cast(floor(cast(cast(dateColumn as datetime)as float)) as datetime),103) "Date"

Hope that helps you.

Well said. I can't believe the pompousness and insensitivity of the jerks who display dates as MM/dd/yyyy. I find it incredibly irritating and threw out Sunbird because of that. Too bad I can't throw out the corporate apps.

User control problem

I have a user control and I don't want some properties automatically generate value by the designer.
I search MSDN and just see that I can use DesignOnlyAttribute class but it is not suitable for my situation.
How could I do that?

Thank for your help.

Hello,

I think the "DefaultValue" Attribute is what you are looking for.
If it's equal to the designtime setting, it will not generate code for this property.
Be aware that the property has to be initialized correct.

Hope it helps!

All the best,

Martin

Your joking, right? If you have no idea how a purchasing system works, you have to get with the customer and find out, and very specifically. Your code is going to model the process of purchasing. Without knowing how one works, you're pretty much not going to be able to do this project at all.

I think u r making a project which is client specific not a generic software that everyone can use.. so it's better for u to arrange some meetings with your client and get a better understanding how the perform their tasks...

and then according to your understandings and with the acceptance of your client u can make your software using RAD process

hope i clear my point of view to u.
