I have worked with 2 automation projects. Where i have to test the API's, whether they are working correctly based on the input and check the output.
In that case, we wrote a COM DLL as the interface between the COM EXE and the test data.
where our input is passed from the VB scripts.
In another one, we used INI file to configure the input and the exe read the input from the INI file and pass it to the DLL that is to be tested, which holds some library.
Now tell me whether your case match any of these?

matched with none..
actually COM server testing not an issue..World has given some standards to extract information from COM environments like TLB's(we can extract every info methods,params and their types and nature, structures, modules, co classes) easily. As these are standards which 3rd party can use to extract info from this e.g ITypeLib .....All Correct!! and I have done this.
I have stored all TLB parsed info as INI or XML and its ready for input for other frameworks.
I have BIG PROBLEM about Win 32 DLL's. MS or others have not given any standards for Win32 dll's from every aspect(like how many functions contained by DLL, how many parameters as input for every function, how many structs ,modules,interfaces,imports & exports a dll have) ..So how can we parse these DLL's and can extract information (statted above) from DLL's.
e.g KERNEL32.dll (its Win32 DLL) contains how many functions, return types of these functions, input parameters and output parameters,types of these params, modules and structs it contain.
One way is PE Parsing..With this way we unable to get parameter types,names and return type of function(but we get fully decorated name of method..with some HEX stuff)
Finally header file remains(as suggested others), but dont know how much difficulties can produce in this way.
Moral is DLl's have no standards contrast with COM which have defined standards.

DLL are hard to reenginner. 
You need either the header or a documentation for it.
Else trail and error with some freaky methods

If your DLL has debug information then you can use DIA (Debug Interface Access) SDK, which will extract information from the pdb files.

OK..!!
As we know that we can extract information like imported/exported functions after parsing PE file programatically.
But we can only take the names (function names imported/exported) of methods. We cannot look up their parameters(in/out)names with their types and return type of method.(as these parts encoded as HEX)
Is there any way out to extract these as well..?

Hi All,
I want to develop an 3D Image rendering software using DIRECTX which can perform some 3D Operations.My customer wants the software developed on .Net Framework.
I have experience in coding in MFC in VC6.0.If i develop an application in MFC dialog based application in Visual Studio 2008,will it be built on .Net Framework?
Also,i have done some image processing coding in C++.Basically i have some classes defined in .h and .cpp files which i want to include in the .Net application which i am going to develop.
For the above requirements should i go for VC++.Net(Forms based developed in VS 2008) application or VC++(MFC based developed in VS 2008)?
Please advice.
Thanks ,
Ashwath.

I would use C#.

Well, why does the customer tell you what technology to use to build a software? Shouldn't you (the developer) be suggesting what's best for accomplishing a given task?
You could wrap your C++ image processing code into a COM dll and use it from C#, instead of writing the whole thing from scratch in C#.

Why bother with COM? It's simple enough to write DLLImport statements and use a native C++ DLL as is.

by writing functionalities in COM u'll be able to build it as server components and call them in any technology(e.g C#)as client and can perform out of process calling easily..
DLL's always not allow you out of process calling untill RPC which's tough to manage.
So I think writing COM dll in VC++ idea is better and integrating it with C# will blend things moore significant way..

Thank you very much for the advice.Well,if i develop the software using
VC++(MFC) in Visual Studio 2008 IDE, will it be built on .Net framework.Why i ask is because i have good experience in VC++(MFC).
Thanks,
Ashwath.

What are you talking about? Unless you target one of those versions of the .NET framework and write managed code, your application would remain native. Just because you use the VS 2008 IDE doesn't mean your application is built on .NET framework.

Thanks Rajesh for the answer.If i develop a VC++.Net application(Form type),will it be developed on .Net framework.
|
|
|
|
|
You mean a managed c++ (C++/CLI) application? Then yes, it would be using the .NET framework.

Yes, i have choosen the "windows forms application"(Managed c++/cli) type project in the "new project" menu.This is built on top of .Net framework right?
Please advice,
thanks,
Ashwath

Yes Ashwath, you're correct. If you choose the c++/cli type project, then that would be using the .NET framework.

definitely C#.net as suggest earlier
and surely OpenGL.
And if you use nvidia GPU then performance of 3D rendering will be very high, [^].
But surely difficult to write the programe with GPU

Hi
My application is such that I have a main dialog class which interacts with the User, at the same time another complete class that performs all background functions needs to be running simultaneously.
Please suggest a method of how that can be executed. On start of application both classes have to be initialised. The background class cannot be called by a button or any other user interface method.
Thanks a ton

Then you have to make two classes
one on main thread, and another on worker thread.
Where main thread should interact with the user actions, while the background processing is done by worker thread.
On the OnInitdialog of main dialog, you can start the worker thread.
Worker thread can be created using AfxbeginThread or CWinthread [^]

Thanks adam
can you also help me with the syntax of the thread function and how the class should be called from the thread function

Multithreading is a fairly complex subject. While you may get away writing multithreaded code by reading online articles, I strongly recommend that you read a book chapters devoted to this subject.

If a worker thread is what is needed, then AfxBeginThread() and a thread function is the ONLY correct way to go (as far as MFC usage is concerned).
Deriving from CWinThread is needed only when a message pump for the thread is needed (so called "UI thread").
