calling unmanged code from j#

Yeha, instead of C#, use MC++ with your MFC code.

Not really a problem I would say. You can have an assembly written with MC++ that mixes unmanaged and managed code. And then you just reference that assembly in your main project where the usual C# Windows forms code lives.

Tom Archer and Nish have written a book about MFC and .NET. May be it's out by now. (Google is your friend.)

I am looking at using CBO's to intercept all method calls made on local objects, to queue these calls and later replicate them on remote objects. Obviously, there is quite a performance hit with this approach, but the number and frequency of method calls are both low. Has anyone here had enough experience with CBO's to share some implementation caveats?

i have an unmanaged dll that exports a function that takes a TCHAR* parameter. i need to call this function from j#. in my j# file, i tried to set the marshal attribute like so,

public static native void testStringFunction(/** @attribute MarshalAs(UnmanagedType.LPTStr)*/String s);

when i call that function, my string is not marshaled to a TCHAR*. i tried all the different string types in the UnmanagedType enumeration. anyone have any ideas??

thanks.

Did you attribute it with the DllImportAttribute, specifying the right native DLL? You should also specify in that attribute CharSet=CharSet.Auto. Other than that, your code looks fine.

In my app I want to create some tool windows, which can be auto-hide and docking like that tool windows of VS.net, with VC++.net. But I looked the MSDN and some samples, the tool window is like only to be created as addin to be used by other app. Please tell me how to do, thank you very much.

If you have some samples , could you send to me?

Including .net framework in project

I was wondering if someone could direct me to some documentation on how to include the .net framework redistributable in my deployment project.

It can't be done.

Deployment machine have to have .NET framework pre-installed before installing .NET application. I am assuming you are talking about .NET Windows application.

For the case of Web Application, you need to install .NET framework only on the web server.

Hope this helps.

Yes it can be done. Read below

Look up the following words on MSDN online and the MSDN library
- dotnetfx.exe
- dotnetfx.msm (which is by the way available in the VS.NET cds)
- merge module
- bootstrapper

Could you please send the link to where it says how we can build the Windows Application setup, so that it reduces the burden of installing .NET framework on client's machine before deploying/installing .NET windows application.

If this is really true, it will save me some of work I do for Application deployment.

I didn't quite understand what needs to be done for such deployment from your reply.

Any help is appreciated.

Thanks

Here is an entry-point[^]. (watch out for the links)

And don't forget to check out what's in your VS.NET cds.

[update] Yet another bootstrapper[^].

You must also distribute MDAC 2.7 or higher

Heyas all,

I'm comming from the *nix dev, attempting to learn some Windows now. My question is, Is there a particular reason a programmer would choose say VB.NET over X#.NET or vice versa? Do all the languages get to the same place and it's just a matter of which langugage the programmer likes better or is each language used for a different purpose.

Thanks all!!

Well, for the most part, they're the same as far as what they can do. I find C# to be more concise and readable. Also, you can use pointers - although they aren't necessary for that much. I use them for image processing, and that's about all.

Really, it all comes down to syntax and personal preferences.

Programs that are written in C# or VB.NET all compile down to the same MSIL. Typically it breaks down to your comfort level with the language. In fact the only differences you should see in the MSIL of a C# vs. VB.NET should be compiler optimization.

So if a programmer (well ok me) were comming from a unix environment and knows C/C++ like the back of his(my) hand, it would generally make sense to choose C# as his(my) language of choice. Unless he(I) wanted to learn VB.

Yes. BTW, one more thing I forgot to say - VB.NET is much less optimized than C#, so it runs slower.
