Now that you ve got your Upcoming block, complete with API key, added to the design surface, it s time to configure the Virtual Earth block s properties. This block (see Figure 4-15) has four operations: addPushpin: Adds a pushpin to the map at a specific location setMapView: Sets the viewable area of the map drawLine: Draws a line from point to point on the map deleteAllPushpins: Removes all pushpins from the map

Note The Virtual Earth block is a presentation block. You can t have more than one presentation block on
the design surface. If you try to drag another Virtual Earth block onto the design surface, Popfly will display an error.

2. Connect the two blocks by clicking the right connector on the Upcoming block and
dragging the line over to the left connector on the Virtual Earth
3. Select addPushpin from the Operations drop-down menu. 4. Because you ve only connected the Upcoming block, the Source drop-down menus
are set to it by default. You should also see the two values automatically selected by looking at the properties passed by Upcoming: latitude is selected for the latitude field and longitude is selected for the longitude field. In the title field, select Upcoming as the source and name as the value . In the description field, select Upcoming as the source and description as the value.
5. Return to the design surface, and click Preview. The music events in Upcoming are
retrieved, and a pushpin is added for each event s location (see Figure 4-16). If you hover over the pushpin, the title and description are displayed.

Customizing the Virtual Earth Block
The Virtual Earth block focuses on the United States by default, so it s great if you want to see all of the events in the United States, but you re probably interested in events only in your local area. We are going to use some of the advanced capabilities of blocks to set the map to a particular location.
Setting the Location of the Virtual Earth Block
We will set the location to the San Francisco area:
1. Click Customize to return to the design surface. 2. Open the properties of the Virtual Earth block by clicking the wrench. 3. Click the Advanced View label to display the code in Listing 4-1. Listing 4-1. Default Code in the Virtual Earth Block Advanced View data["Virtual Earth"] = new Array(); pendingCalls["Virtual Earth"] = data["Upcoming"].length; for (var i=0; i<data["Upcoming"].length; i++) { try { data["Virtual Earth"][i] = virtualEarth.addPushpin(~CCC data["Upcoming"][i].latitude, data["Upcoming"][i].longitude, "", data["Upcoming"][i].name, ~CCC data["Upcoming"][i].description); pendingCalls["Virtual Earth"]--; if (pendingCalls["Virtual Earth"] == 0) environment.finish(); } catch (ex) { pendingCalls["Virtual Earth"]--; if (pendingCalls["Virtual Earth"] == 0) environment.finish(); environment.reportErrorInLoop(i, ex); } }
The code is generated automatically when the Upcoming block is connected to the Virtual Earth block. We don t want to change any of pregenerated JavaScript code, but we
C HA PTER 4 M ORE MAS HU P EXAMPLES
will add to it. The most important block of code is the JavaScript within the try block. The try block is a way to trap errors. The code after the word try, and enclosed in between the curly braces ({}) is the heart of the block execution and where we want to add our code. The catch block will be executed if an error occurs.
Configuring the Parameters of the Virtual Earth Block
We will be using the setMapView function. Though it has seven parameters, we will be using only two: latitude and longitude. In order to set the map to the correct location, we need the longitude and latitude of San Francisco. You can find the location on the Internet in various locations; see the Geoencoding Resources sidebar for more information.
