VS .NET and Images - Solved

After having a conversation with Jamie, we were able to figure out a way to get the project directory at runtime. I’ve updated the code example (I even updated the class names - I was so happy!) - it basically comes down to doing three things. First, get the location of the assembly in the constructor for a default directory value.

public DrumPicture()
{
  this.InitializeComponent();

  Assembly targetAssembly = (Assembly.GetEntryAssembly() != null ?
    Assembly.GetEntryAssembly() : Assembly.GetCallingAssembly());

  this.loadingDirectory = 
    Path.GetDirectoryName(targetAssembly.Location);
}

Next, override the Site property to determine if the control is in design-mode and, if it is, get the location of the project through the DTE:

public override ISite Site
{
  get
  {
    return base.Site;
  }
  set
  {
    base.Site = value;

    if(base.Site != null)
    {
      ProjectItem projectItem = 
        (ProjectItem)this.Site.GetService(
          typeof(EnvDTE.ProjectItem));

      if(projectItem != null)
      {
        this.loadingDirectory = 
          Path.GetDirectoryName(
            projectItem.ContainingProject.FullName);
      }
    }
  }
}

Finally, override OnLoad() and load the image there:

protected override void OnLoad(EventArgs e)
{
  base.OnLoad (e);
  this.drumPictureBox.Image = Image.FromFile(
    Path.Combine(this.loadingDirectory, "DrumsFront.jpg"));
  this.locationLabel.Text = this.loadingDirectory;
}

That’s essentially it. Thanks again to Jamie for helping me out on this.
