VS2008, C#
In several of my business objects, I'm lazily loading some data that requires a call to the DB. This presents a problem when trying to quick watch the parent object. When it hits that...

I'm curious as to why you can't use a label. I only use a textbox as a label for 2 circumstances:
1) I need to a readonly display that will still allow the user to copy the data from the control....

Hey thanks, I was wondering this myself a few days ago. :)

I don't have many specifics as I've yet to delve into this a lot yet, but research the VirtualMode property on the DataGridView and see how you can use it. VirtualMode only renders the rows the user...

Heya. :)
I've got a quirky thing happening with databinding in C#, .NET 2.0, CSLA 2.something, and my databinding.
The user hits a button, i popup a modal, populate some comboboxes on the...

You may want to explicitly tell your SqlCommand object that the CommandType is a StoredProcedure:
nonqueryCommand.CommandType = CommandType.StoredProcedure;
I'm not sure what the default is...

So I'm playing with a screen in our system. On the screen are a few comboboxes that we have databound to a list of stuff from a cache. Dictionary type stuff that we don't have to go to the database...

Replace the catch bit of my example with this:
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
This is also permissable:

Quick google search revealed this:
int i = 100;
string str = Convert.ToString(i, base); //base = 2, 8,10 or 16
You'll obviously want to use base 2 for binary.

In order to maximize the window of the .exe, you'd somehow have to match up the Process with the window handle. Unfortunately I'm not sure how to do this. :(

Are you trying to figure out what hash function the Hashtable uses? It's probably object.GetHashCode().

Perhaps you have to specify the owner of the modal?

Your other options include inheriting from System.Drawing.Image. Bitmap actually inherits from Image, anyway.
Or you could use what's called extension methods.

Yep, set the width of the ColumnHeader objects to -2. For instance:
foreach (ColumnHeader ch in lvList.Columns)
{
ch.Width = -2;
}
Try it!

You're going to want to take a look at the System.Diagnostics.Process class. Inside of it it has a StartInfo class that you can fill in with executable location data.

Yup, nested classes are instantiated the exact same way as all the others. For instance:
public class Class1
{
public class NestedClass1
{
}
}

@zdavis - I don't see any nested classes in your example. Maybe a misplaced bracket?
@JustSomeGuy - What I'd suggest here is to just try it out. Nested classes in C# are very useful for limiting...

You may want to provide a link to the example you're referring to. We don't know if you're talking about ASP or WinForms. I dunno if it'd matter much, but more context never hurts.
