4.4. Controlling the WEBMCA Server via DLL
The WEBMCA server program provides - via a DLL („dynamic link library“) - access to all
functions, parameters and data. So the server can be completely controlled from the MCDWIN
software that provides all necessary graphic displays.
In the following some parts of the header and definition files of the DMCA.DLL are listed, that may
help an experienced programmer to use the DLL for own written applications. Please note that the
complete documented source code of the DLL including fundamental VI’s and an example VI for
LabVIEW and example program in Visual Basic is available as an option.
