COM interoperability

[edit | edit source]

Exam objective: Expose COM components to the .NET Framework and .NET Framework components to COM

(Refer System.Runtime.InteropServices namespace)

Exposing COM Components to the .NET Framework

[edit | edit source]
First there is an article in the .NET developers guide that covers the first part of this section, see MSDN

Import a type library as an assembly - MSDN

Add references to type libraries
Same link as above, see second paragraph.
Type Library Importer (Tlbimp.exe) - MSDN
Generate interop assemblies from type libraries - MSDN
Imported Library Conversion - MSDN
Imported Module Conversion - MSDN
Imported Type Conversion - MSDN
Imported Member Conversion - MSDN
Imported Parameter Conversion - MSDN
TypeConverter class - MSDN

Create COM types in managed code - MSDN

Compile an interop project - MSDN

Deploy an interop application - MSDN

Exposing .NET Framework Components to COM

[edit | edit source]
The rest of the objectives of that section directly refers to MSDN

Qualify the .NET Framework types for interoperation - MSDN

Apply Interop attributes, such as the ComVisibleAttribute class - MSDN

Package an assembly for COM - MSDN

Deploy an application for COM access - MSDN

Call DLL functions

[edit | edit source]

Exam objective: Call unmanaged DLL functions in a .NET Framework application, and control the marshalling of data in a .NET Framework application.

(Refer System.Runtime.InteropServices namespace)

Platform Invoke - MSDN

Create a class to hold DLL functions - MSDN

Create prototypes in managed code - MSDN

DllImportAttribute class - MSND

Call a DLL function - MSDN

Look for "P/Invoke" on the internet.
A good reference is: http://www.pinvoke.net/
Some short hints:
  • For the DllAttribute "CharSet", Logically, CharSet.Auto is the most secure way as this will autodetect the Charset used. The CharSet can be ANSI(Win95/Win98/ME) or Unicode (Win2000/WinXP)
  • GetEntryPoint: There could be one tricky question as the EntryPoint states the method that should be called. In case the name of the method used differs from the method to be called, this flag is necessary.

Call a DLL function in special cases, such as passing structures and implementing callback functions

Same link as above
Passing structures - MSDN
Implementing callback functions - MSDN

Create a new Exception class and map it to an HRESULT - MSDN

Default marshaling behavior - MSDN

Marshal data with Platform Invoke - MSDN

Marshal data with COM Interop - MSDN

MarshalAsAttribute class and Marshal class

MarshalAsAttribute class - MSDN
Marshal class - MSDN

Implement Reflection

[edit | edit source]

Exam objective: Implement reflection functionality in a .NET Framework application (refer System.Reflection namespace), and create metadata, Microsoft intermediate language (MSIL), and a PE file by using the System.Reflection.Emit namespace.
