Miraplacid Text Driver SDK Installer Component Reference
Miraplacid Text Driver Installer Component
Miraplacid Text Driver SDK Edition can be installed from special Installer Component.
This is self-extracting DLL file which can be used from external setup utility.
This file is not present in the package; it could be generated with special utility,
Setup Maker.
Installer component exposes two kind of interfaces: DLL exported funstions (API) and COM interface.
COM interface allows extenal program to have detailed information about installation process.
COM parameters are: coclass MTDSsetup (Miraplacid.MTDSetup {8BB15E2B-71EC-4c7d-BA6B-3C913DC3E1A7}).
It contains two interfaces: IMTDSetup {CD78360C-D3BA-4b0b-BC53-F008ECBF4F0F}, the main interface, and
connection point interface _IMTDSetupEvents {EA50BBB8-9FF4-4731-A670-28BCBA417BCC} for installation events from Installer component
to external software.
Examples of setup utility are located at examples.vb\setupui and examples.net\MTD_SE_Setup folders at this package.
Important note: If you will use installer component from your
.Net setup program, please, do not forget to build it as a 32-bit executable,
if your installation application will register dll server itself. Or, it may call system application "regsvr32 mtd.dll" to register mtd.dll server.
