uLanguage

The primary language for your Source or application. Use the constants for the CAP_LANGUAGE capability found in the Twain Specification.  i.e. TWLG_ENGLISH_USA, TWLG_GERMAN, etc.  See www.twain.org for a link to the Twain Specification.

uCountry

The primary country where your Source or application is intended to be distributed. i.e. TWCY_USA, TWCY_GERMANY, etc.  For a list of possible values, see "Data Types and Data Structures" section under "Constants" in the Twain Specification.

Comments

pAPPLICATIONDATA is a pointer to a APPLICATIONDATA structure. Where the function parameter type is pAPPLICATIONDATA, you can declare an APPLICATIONDATA variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pAPPLICATIONDATA variable is necessary only if your program requires a pointer.

APPLICATIONDATA is used with the LTwain::InitSession function.
