File Constants

This section describes variables that provide file names, constants, and product information

File Names and Initialization Constants

These variables define file names and other constants.

Variable name	Description
HlpMax	This number should be set to one more than the maximum value of the context-sensitive Help identifiers.
HlpMin	This number should be set to one less than the minimum value of the context-sensitive Help identifiers.
ShellCode	This variable holds the error return code from all shell executions and is set by the Setup Engine itself. A value of zero represents success; all other values represent errors.
SubroutineInf	This .INF file contains some of the utility functions used by both SNA Server Setup and Windows NT Setup.
ThisFile	This variable should hold the name of this .INF file without the extension. Defining it here is the only way to access this information in the setup script.
ThisHlp	The full name of the WINHELP file for this setup script.
ThisInf	The full name of the setup script.
ThisSrl	The full name of the Setup Resource Library for this script.
UtilityInf	This .INF file contains all of the SNA Server Setup utility functions.

Product Information

This section contains all the information about a single component. There should be a section of this form for each of the options supported by this script.

Variable name	Description
FullInfName	The full path to this setup script (.INF file) after installation.
NetRulesClass	The class to which this product belongs for bindings determination by the NCPA.
ProductDepends	This variable holds the dependencies of this product. This value is only used in the creation of the product service key.
ProductDll	The dynamic-link library that should be linked to by the control APIs for this component. This variable is only necessary for link services and should be given a null value for all other cases.
ProductExclusive	This variable dictates the behavior of multiple attempts at installing this component. It can hold one of three values: FALSE: This product is not exclusive and can be installed as many times as the user chooses. TRUE: This product is exclusive and can only be installed once. NOTIFY: This product is exclusive, and the user should be informed of this fact. SNA Server Setup displays a message to inform the user.
ProductExtraParams	This variable holds the entries for the ExtraParameters subkey of the product service key. It is recommended that any modifications to the value of this parameter be done in the body of the setup script with the rest of the assignments. This line serves as the initialization for this variable.
ProductFullName	The actual value used to represent this product in the registry. It is a combination of the product name and version, separated by an underscore.
ProductImagePath	The file name of the executable image for this product. This can be an executable file or a system file. For a link service, this variable must always contain the value SNALINK.EXE.
ProductName	The name of this product. This name is used in conjunction with the version to provide the full name of the registry entry for this product.
ProductParams	This variable holds the entries for the Parameters subkey of the product service key. It is recommended that any modifications to the value of this parameter be done in the body of the setup script with the rest of the assignments. This line should not be deleted since it serves to initialize this variable.
ProductRegBase	The specific location for this product's registry entry under the SOFTWARE registry key. This variable should not be changed since all the SNA Server components should reside under SOFTWARE\Microsoft in the registry.
ProductServicePrefix	A prefix that is used to algorithmically decide the service name for this component. Service names for SNA Server are limited to no more than eight characters. Since SNA Server Setup attaches a single-character suffix based on the index, this prefix should be no longer than seven characters.
ProductType	An internal representation of the type of component this option belongs to. Currently, this variable can take on the values of Link and Driver. Note This value is currently unused in the SNA Server scripts; however, it should still be set since its usage will be implemented in the future.
ProductVersion	The version of this product (component). This number is used in creating the registry key for this product under the SOFTWARE key of the registry.
ServiceType	This variable is used to declare the type of this component for usage with the NCPA bindings.
SNAServiceType	A more specific description of the type of component this option represents. It should be set to one of the values specified in the SNAServiceTypes section of the UtiltyInf file.
