Comments

The DTWAIN_SetAppInfo function sets the user application information that is used by the Source Manager. The strings can be used for any purpose that the Source Manager and any Sources sees fit. For example, the Source user interface may display the application version name and manufacturer. These strings are not mandatory, but it is always a good idea to set these values to whatever strings you feel are appropriate.

The application version, szVersion, is usually the version of your application. For example 'Version 2.1'. szManufacturer is usually the manufacturer or creator of your application, for example 'Dumbbell Software'. The szProdFamily maybe 'Lite Version' and szProdName is usually the name of the application ('Disk Defragger' for example).

Important Note: Only the first 31 characters of each string parameter are recognized.

If DTWAIN_SetAppInfo is not called, all of the information strings default to the character sequence '<?>'.

DTWAIN_SetAppInfo must be called before the TWAIN session is started with (done by calling or before a Source is initially selected), since a TWAIN session sends the application information to the TWAIN Source Manager.

TWAIN State Transitions

None.
