I have to question your use of a date value in a string format...

Agreed. But consider this nuance. If I return a DateTime for use in a "between" clause in SQL, I have to serialize it to a string anyways because I can't use parameters. That's another oddity in itself. Can you say "SQL injection attack"? So, instead, I could write the SQL code to strip off the time when I pass in the string. Yuck. I just want something that's a G.D. date! And then you have the mixup between XSD date and time types, time zones, and, oh god, let's not go there today. X| Marc

...I rag on the .NET framework. Here's two lovely examples. The DateTimePicker. Utterly useless as a control that's bound to a nullable field. Utterly useless for creating a "between" query that just needs the dates because when it's converted to a string, it includes the time component unless you do special stuff, even after setting the control to just providing a date picker. Workaround: a new nullable property:
public object NullableValue
{
get
{
// We just want the date with basically a default (but constant) value for the time.
// Get the short date string, as we don't want any time component,
// which hoses up SQL Server's "between" clause if there's a time component.
return Value.ToShortDateString();
}
set
{
if ( (value == null) || (value==DBNull.Value) )
{
Value = DateTime.Now;
}
else
{
Value = Convert.ToDateTime(value);
}
}
}The DataGridView. Select a row and delete it. OK, the "selection list" selects the next available row. Unless you delete the last row. Then the selection list Clears even though the current position has updated to the now last row. Workaround? This inane code to reset to binding source position which forces the selection list on the DataGridView:
protected void OnDeleteRow(object sender, EventArgs e)
{
IXDataGrid grid = (IXDataGrid)IXControl.GetControlByName(dataGridName, (IXForm)
IXControl.FindForm(this));
BindingSource bs = (BindingSource)grid.DataSource;
bs.RemoveCurrent();
UpdateButtonState(grid);if ( (grid.SelectedRows.Count == 0) && (bs.Count != 0) ) { bs.Position = 0; bs.Position = bs.Count - 1; }}
In both cases (well, if I can find the solution to the grid problem), not a total rewrite of these controls, but requiring a derived control to work around the bugs. Oh, excuse me. Features. And this was not a programming question in the lounge. Talk to the hand. :| Marc

Nullable types came along much later, and I guess they have not updated the control yet ( or ever, I admit )

Touche. In other words, it's reasonable to assume that Microsoft puts out junk for its .NET control library. Hmmm. Now exactly why shouldn't that reasoning be extended to other aspects of the framework then? Like WPF? Like communications? Hmmm? Marc

No, in other words, much of the framework targets people who can't code and want to see something for free. Half of it, I would never use in a serious app, but I know what it's there for.

But before we had to write code that used magic numbers, at least we can bridge the two null concepts for value types now.

I just use DateTime and pull out the part I want, I've never seen that as a huge issue.

Agreed. But sadly, a lot of this stuff falls apart when its used in conjunction with other gloriosky techniques, like data binding, automatic parameterization, validation, serialization, and so on. Taken one at a time, it's ok, but you start stringing these technologies together to form what you think should be a highly automatable process and *bang* it implodes on you. Marc

DataBinding works fine, you can format your data in the binding statements I don't use any of the stuff that automatically binds to a SQL source via SQL in the presentation layer, that's an example of nastiness not fit for real world code. Validators are another story again, but are a toolkit of simple common usages, and the ability to write your own if needed. I don't think you're wrong, I just don't think it's surprising.

I honestly think that they've decided that bug fixes are not as important as pushing out the next set of features. I've worked for many a small company that used this tactic in the short run to prevent competitors from gaining market share. But, It is still makes no sense to me in this instance since they (MS) effectively have no real competition in the windows developer space.
