As I discussed in my last post, we created a TimeSpinner control based on the Extended WPF Toolkit’s ButtonSpinner.
Now, the toolkit has a DateTimeUpDown control that will display a date or time and allow the user to click the spinners for each time part, but I needed a little more. I needed the raw text to be editable and I wanted the spinners to just modify the minutes portion. I also wanted to have special parsing based on the number of characters entered.
4 chars:
Parse as military time.
3 chars:
Parse as modified military time, but only assume waking hours.
So 933 becomes 9:33 AM
345 becomes 3:45 PM
We put the cut-off at 7. Anything before 7 assumes PM anything 7 or after assumes AM.
2 chars:
Assuming shortened military time.
12 = 12:00 PM
15 = 3:00 PM
1 char:
Parses as shortened military time, but assumes waking hours like 3 chars.
1 = 1:00 PM
8 = 8:00 AM
The TimeSpinnerControl exposes one bindable property, Time. So it would be consumed like:
1: <runtime:TimeSpinnerControl Time="{Binding Path=ReturnTime}" 2: x:Name="spinnerReturnTime"/>
So, here is what we did:
TimeSpinnerControl.xaml:

Our software will automatically generate pick up and drop off times based on distance of trip, how many other people are on the bus, how long it takes to drop them off, etc. We display these times in our custom TimeSpinner control based on WPF Extended Toolkit’s button spinner.
Since the computer is generating the time, they are often not human-friendly. 6:00 AM is a lot easier to remember than 6:03 AM. So we give the users the option to modify these times. Using the spinners, they can adjust the time 5 minutes up or 5 minutes down. However, 6:08 is still difficult to remember, so what we really need is to be able to round up (or down) to the nearest 5 minutes, then adjust in 5 minute increments after that.
So 6:03 AM to 6:05 AM to 6:10 AM to 6:15 AM and likewise, round down from 6:03 AM to 6:00 AM to 5:55 AM to 5:50 AM.
We used an extension method to accomplish this. Note that it accepts increments other than 5 minutes, that’s just what we use.
1: /// <summary>
2: /// Adds or subtracts a value to a date time rounding it to
3: /// multiples of the entered value

7: /// <returns>Adjusted DateTime</returns>
8: public static DateTime AddMinutesRoundUp(this DateTime dt, int value)
9: {
10: int delta = dt.Minute % value;
11: int subtractDeltaFrom = 0;
12: //if value to add is negative, we want to round down
13: //to nearest delta value
14: if (value < 0)
15: {
16: //but only if delta is more than 0. If delta is 0,
17: //then we are already rounded down
18: if (delta > 0)
19: {
20: subtractDeltaFrom = Math.Abs(value);
21: }
22:
23: }
24: return dt.AddMinutes(subtractDeltaFrom - delta).AddMinutes(value);

Sometimes it handy to force the user’s attention to a specific screen. We can do this with a dialog, but sometimes the user doesn’t know that window is on top. To draw the user’s eye to the window, I like to place a backdrop between the rest of the application and the dialog window. I use the following code to make that happen.
1: public bool? ShowDialogWithBackdrop(Window win)
2: {
3: //create backgroup
4: Window backgroundWindow = new Window();
5: backgroundWindow.Top = 0;
6: backgroundWindow.Left = 0;
7: backgroundWindow.Height = SystemParameters.WorkArea.Height;
8: backgroundWindow.Width = SystemParameters.WorkArea.Width;
9: backgroundWindow.AllowsTransparency = true;
10: backgroundWindow.Background = Brushes.Transparent;
11: backgroundWindow.WindowStyle = WindowStyle.None;
12: backgroundWindow.ShowInTaskbar = false;
13: Rectangle rect = new Rectangle() { Fill = Brushes.Silver, Opacity = 0.5 };
14: backgroundWindow.Content = rect;
15: backgroundWindow.Show();
16: //set the owner so if the user clicks on the backdrop,
17: //the window will flash
18: win.Owner = backgroundWindow;
19: bool? rv = win.ShowDialog();
20: //dialog has returned. Close backdrop.
21: backgroundWindow.Close();
22: return rv;
23: }

The most common use for Preprocessor Directives is to intelligently group your code using the #region … #endregion tag (sidenote: Ctrl + M, M is a great keyboard shortcut to expand and contract your regions). Preprocessor Directives can also be used to tell the compiler which code should or should not be compiled based on the configuration environment. Wrapping code in an #if DEBUG … #endif block will only execute if the environment is in debug mode.
This proved to be a handy way to debug a situation this morning in a multi-threaded scenario where breakpoints and Console.WriteLine were not giving me enough information. I added a new tab with initial visibility as collapsed, set it to visible in an #if DEBUG … #endif block, and wrote events to it also in a debug block.
For situations where you want code to execute only in a production environment, use #if !DEBUG … #endif.
View MSDN’s page on Preprocessor Directives for more information.

There is a sales technique where the strategy is to get the customer to say “No deal” as soon as possible. The idea being that by establishing terms that your customer is not comfortable with with, the sooner you can figure out what they will be willing to agree to. The same principal can be applied to code design. Instead of nested if…then statements, a code block should quickly eliminate the cases it is not equipped to handle and just focus on what it is meant to handle.
This is code that will quickly become unmaintainable as requirements change:
private void SaveClient(Client c)
{
if (c != null)
{
if (c.BirthDate != DateTime.MinValue)
{
foreach (Sale s in c.Sales)
{
if (s.IsProcessed)
{
SaveSaleToDatabase(s);
}
}
SaveClientToDatabase(c);
}
}
}
If an additional requirement comes along that requires the Client to have Manager approval or for a Sale to be under $20K, this code will get messy and unreadable.
A better way to meet the same requirements would be:
private void SaveClient(Client c)
{
if (c == null)
{
return;
}
if (c.BirthDate == DateTime.MinValue)
{
return;
}
foreach (Sale s in c.Sales)
{
if (!s.IsProcessed)
{
continue;
}
SaveSaleToDatabase(s);
}
SaveClientToDatabase(c);
}
This technique moves on quickly when it finds something it doesn’t like. This makes it much easier to add a Manager approval constraint. We would just insert the new requirement before the action takes place.

A lot of reports work on data from last month. It is a nice touch to have these dates pre-populated for your users. Using extension methods, the code can look cleaner too.
Extension Methods:
public static class DateHelper
{
public static DateTime FirstOfTheMonth(this DateTime dt)
{
return new DateTime(dt.Year, dt.Month, 1);
}
public static DateTime LastOfTheMonth(this DateTime dt)
{
return dt.FirstOfTheMonth().AddMonths(1).AddDays(-1);
}
}
Consuming Code:
void Prepopulate()
{
startDateBox.CurrentlySelectedDate = DateTime.Now.AddMonths(-1).FirstOfTheMonth();
endDateBox.CurrentlySelectedDate = DateTime.Now.AddMonths(-1).LastOfTheMonth();
}

I would like to blog more about the problems I encounter on a daily basis. I find that taking 10 minutes or so to write a simple solution to my problems helps me retain that information.
I always forget the specific syntax to declaring variables in T-SQL.
declare @startdate datetime;
declare @enddate datetime;
set @startdate = '04/01/2010';
set @enddate = '04/30/2010';
select count(id) from triphistory where tripdate between @startdate and @enddate

We recently added OAuth to MentionNotifier so that users can quickly view and edit their subscriptions without needed an additional login. This is enabled by default for new users, but existing users will need to do the following steps to associate their subscriptions with OAuth:
1) Go to http://software.engraph.com/ManageMentionNotifier
2) Click “Sign in with Twitter”
3) Verify that your twittername and email are correct
4) Click "Associate with OAuth"
This will also allow you to reply to notification emails and MentionNotifier will tweet on your behalf. This is made possible by @sidePop written by @ferventcoder
Note that the reply by email is new and buggy, so make sure that what was tweeted is correct and as expected.
If you run into any issues, sent me a reply to @timhibbard.
You can also join the MentionNotifier fan page on facebook, or follow @MentionNotifier on twitter.

If you want to specify that a virtual server starts up automatically when the host server starts up:
1) On host server, browse to “C:\Users\Public\Documents”
2) Right click “Shared Virtual Machines”, select Properties
3) Browse to security tab, add yourself as having full control over this folder
4) Repeat steps 2-3 for “Shared Virtual Networks”
5) In Virtual Server web interface, shut down the virtual machine you wish to auto-start
6) Navigate to Edit Configuration –> General Properties
7) Check “Run virtual machine under the following user account”
8) Enter the credentials from step 3
9) Select desired startup action and delay, then start virtual machine.
Now when your host machine reboots, your virtual machines will start up automatically. Step 4 is very important as my wasted morning can attest to.

Last weekend I ran the Shoreline Shuffle trail 5K. It was my first trail race and also my first first place finish. As a bonus, I also broke 20 minutes, which I didn’t think was possible for me on a trail run. I’ve posted a full race report (with way too many pics) on my running blog.

TwitApps was a great tool, it would email you when somebody @mentioned you on twitter. But, alas, they are shutting down and leaving what I think is a huge hole.
So I built my own service that does the exact same thing.
To use the service, visit MentionNotifier, and subscribe to your @mentions. To get notified of updates, follow @MentionNotifier or @timhibbard on twitter.
Here are some of the FAQ’s:
Q: What is this?
A: It is a service to notify you by email when somebody has mentioned you in a tweet.
Q: Who do the emails come from?
A: MentionNotifier@gmail.com
Q: How quickly will I be notified of a new tweet?
A: Currently, it checks every minute.
Q: How does it work?
A: It uses the search API of twitter to check for your twitter username.
Q: Isn't that just a glorified RSS reader?
A: Yes.
Q: Will it work with hashtags?
A: Yes. Put in the search string you want to be notified on (#KUbball) and the email address to send new tweets to.
Q: Will I receive multiple emails if I get multiple mentions?
A: It will group the mentions into a single email each checking cycle.
Q: Will it work if I get a mention from somebody that protects their tweets?
A: No, because protected tweets are not part of the public timeline.

I use Gmail for my personal email, and as an archive for my EnGraph email, but haven’t been able to use it as my main email client as it appends a “On Behalf of” to messages sent from Gmail using a non-gmail address.
Google has recently released an update to Gmail allowing you to use an SMTP server of your choosing, which removes the “On Behalf Of”.
Now I can email my clients from Gmail and they don’t know the difference!

This is a great tool for those circumstances where ordinary sarcasm isn’t quite enough to get the point across.

Since my Dell D610 is three years old, I decided it was time for a new lappy. I finally decided on a E6400 from Dell.
Finally a machine that can actually run Vista. Here is my score:
So far I love it. I can have VS 2008 plus a couple virtual machines open and it doesn’t even blink.

I asked my first question on stackoverflow today. I want to make sure I’m unsubscribing from PropertyChanged events properly. Please head over and put in your two cents.

In ParaPlan 4.0, we use twitter to maintain a change log. I wanted to display this information to our users, so I wrote a little class that calls the RSS feed and uses LINQ to parse the data. All I need is the message and the date, so that is all it pulls out.
Here is the class:
public class Twitter
{
public string Message { get; set; }
public DateTime PubDate { get; set; }
public static List<Twitter> Parse(string User)
{
var rv = new List<Twitter>();
var url = "http://twitter.com/statuses/user_timeline/" + User + ".rss";
var element = XElement.Load(url);
foreach (var node in element.Element("channel").Elements("item"))
{
var twit = new Twitter();
var message = node.Element("description").Value;
//remove username information
twit.Message = message.Replace(User + ": ", string.Empty);
twit.PubDate = DateTime.Parse(node.Element("pubDate").Value);
rv.Add(twit);
}
return rv;
}
}
Our calling code looks like this:
var changes = new List<string>();
var fromTwitter = Twitter.Parse("ParaPlan");
fromTwitter.ForEach(t =>
changes.Add(t.PubDate.ToString("MM/dd/yy") + " - " + t.Message));
var list = new ListBox();
list.ItemsSource = changes;

On 12-20-2008, my wife Chelsea, gave birth to our beautiful baby boy Benjamin. It’s been a crazy exciting and busy couple of weeks so far. I’ve tried to respond to all the many people that have congratulated us on twitter and facebook, but if I forgot, thank you so much. All of your kind words and well wishes have been very appreciated!!
Many more pictures here.
