How to Open .Mdl Applications

Hi Karthik,

it cannot be done. You wrote you know C language, so why do you expect .ma file, which is the result of compilation process, could be opened and decompiled back to human readable form?

Under the name "MDL applications" two different options exist:

• MDL C language compiled into pseudocode. It could be decompiled potentially, but no such tool is available. But anyway, this option is obsolete and not supported anymore, despite of tools are still available in MicroStation SDK. And all this old technology will be removed in MicroStation CONNECT Edition, so no big reason to spend too much time wih it.
• Native C/C++ code using C MDL API and C++ MicroStationAPI compiled to dll, where .ma works as loader and store application resources.

If you want to start with MDL now, native C/C++ codde is the way to go. But be aware Visual Studio 2005 is required to produce correct dlls for MicroStation. Or you can jump to comming CONNECT Edition, which requires Visual Studio 2013 and offers more modern API in C++ style.

BTW If you wrote you know C, do you mean C, C++ or both?

With regards,
