The Global.asa file controls the variable properties of the on-line presentation. In Global.asa you define the presentation start and stop time, whether or not the presentation is multicast, the title of the event, and the IP address used to transfer slide images to your users.
How this file is configured differs depending on whether your presentation needs to support viewing by Netscape Navigator clients. The default location of the Global.asa file is SystemDrive\Program Files\Windows Media Components\Tools\Presenter. This path will differ if you choose a custom install location for Windows Media Tools.
The following table lists the variables defined in Global.asa and their functions in Presenter.
| Variable | Function |
|---|---|
| NS_PLAY | The path to a player compliant with Netscape Navigator. |
| NS_CORE | The path to install Windows Media Player if the client does not have it installed. |
| NS_FILE | The path to install the File Transfer Service control if the client does not have it installed. |
| MCSIControls | The path to install a timer control if not already installed. |
| VS_FTS_IP | The IP address for the high-bandwidth file transfer stream created to transfer slides while the user is at the initial Web page, prior to the presentation start time. Replace the IP address that is in quotation marks with your IP address. Used with multicast presentations. |
| VS_FTS_PORT | The port over which the images are sent during the high-bandwidth file transfer. Replace the port in quotation marks with your port. Used with multicast presentations. |
| LOW_FTS_IP | The IP address for the low-bandwidth file transfer stream created to transfer slides during the presentation. Replace the IP address in quotation marks with your IP address. Used with multicast presentations. |
| LOW_FTS_PORT | The port over which the images are sent during the low-bandwidth file transfer. Replace the port in quotation marks with your port. Used with multicast presentations. |
| SHOW_TIME | The date and time that your presentation is to start, specified in Greenwich Mean Time (GMT). For example, if your presentation is scheduled for July 8, 1998, at 1 P.M. in California, the setting would be: "07/08/1998 21:00:00". GMT is used to enable the presentation time and timer countdown to be translated correctly for users in different time zones. |
| SHOW_END_TIME | The date and time that your presentation is to end, specified in GMT. For example, if your presentation is scheduled to end July 8, 1998, at 3 P.M. in California, the setting would be "07/08/1998 23:00:00". GMT is used to enable the presentation time and timer countdown to be translated correctly for users in different time zones. |
| EVENT_TITLE | The title of your presentation that appears on the initial Web page and on the Presentation Web page. |
| ADMIN_NAME | The name of the person responsible for supporting the event. This name appears on the page that is displayed if an error occurs. Completion is optional. |
| ADMIN_EMAIL | The e-mail address of the person responsible for supporting the event. This address appears on the page that is displayed if an error occurs. Completion is optional. |
| VIDEO_WIDTH | The pixel width of the player object. This must correspond to the actual width of the player window as defined by Windows Media Encoder. |
| VIDEO_HEIGHT | The pixel height of the player object. This must correspond to the actual height of the player window as defined by Windows Media Encoder. |
| ASX | The path to the .asx file that is used for the presentation. For example, C:\Public\Presenter.asx. This .asx file is embedded in the Web page and is used to locate the presentation stream. |
| MULTICAST | This variable determines whether or not a Windows Media multicast is used. Enter "True" if you are using a Windows Media server to multicast the presentation and file transfer streams. Enter "False" if you are using another method. |
