I am building a C# ActiveX DLL... do I use REGASM or REGSVR32 to register it?
How do I register the 64-bit interface vs the 32-bit interface?
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr.
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
What is C? C is a general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972. It is a very popular language, despite being old. C is strongly associated with UNIX, as it was developed to write the UNIX operating system.
You need to use regasm.exe
to register both the 32 bit and 64 bit interfaces I believe you need to run each of the regasm.exe
's in:
C:\Windows\Microsoft.NET\Framework\v2.0.50727
and
C:\Windows\Microsoft.NET\Framework64\v2.0.50727
So... in your case you need to run the regasm.exe
in the Framework64\v2.0.50727
folder.
Here's an example we use to register a COM interop DLL for one of our legacy ASP apps:
regasm.exe Hosting.DeviceManager.Power.dll /register /codebase /tlb
If the DLL is build in format of "Any CPU", no matter if you choose regasm in
C:\Windows\Microsoft.NET\Framework\v2.0.50727
or
C:\Windows\Microsoft.NET\Framework64\v2.0.50727
DLL would be registered as 32-bit.
