A Windows DLL may optionally contain descriptive information that may be viewed in Windows Explorer. Right-click the DLL, select Properties and then the Details tab.
The file that contains this information is lansaver.h. The easiest way to edit this file is by adding it to your Project. You should change all the version numbers to your application's version numbers and replace LANSA with your own company's name.
Note that the Product Name is declared in the lansax property sheet in the Resources Preprocessor Definitions. It is supplied with VER_PROD_NAME = Visual LANSA.
The critical attribute for distributing a change in a Windows Installer patch is LANSA_FILE_VER. This number needs to be incremented in order for the DLL to be included in a patch and then installed on the deployed system.
