Hello,
In C# you cannot do everything that you can do with C++. Multiple inheritance is one thing and template meta programming is another. Not that these things are used on a daily basis...
It all comes down to the right tool for the right job. C++ for example is good for writing core parts of an OS due to it's nature in C. C# on the contrary is fantastic for writing pluggable architectures, database applications and web apps due to its simplicity and rich framework that is shipped with the compiler.
IMO C++ is good and C# is good. None is best, but one solves a particular problem better than the other. In short: the righ tool for the right job.

Hello,
1) I have a C# console application that currently is compiled and linked to an external C++ DLL file that contains unmanaged C++ code. This compiles and executes fine.
2) I would like to compile the C# application so that the C++ DLL is compiled into a single C# EXE application so that I no longer need to deliver the C++ DLL separately.
NOTE: My current files separately compiled files are:
C# EXE: POST2STK_Console.exe (size=20 KB)
C++ DLL: POST2STK_LIB.dll (size=41 KB)
I am trying to merge these together using ILMerge, but I keep running into the following issue:
If I compile with the following "Post-build Event Command Line" parameter set in my project's build properties as:
ilmerge /target:winexe /out:TEST.exe POST2STK_Console.exe POST2STK_LIB.dll /zeroPeKind
I do NOT get any compiler errors and get output of TEST.exe as a 25 KB size file. This makes no sense when the sum of orginal EXE and DLL files noted above = 61 KB. More importantly, if I try to run TEST.exe, I also get a runtime Exception "System.TypeLoadException" has occurred in TEST. Which from what I can tell is a result of the fact that the DLL was actually NOT compiled into the TEST executeable when ILMerge was run, even though there were no errors shown when this was done.
Anyone that can offer any assistance on how to get this to work, it would be greatly appreciated.
Thanks!

Quick answer: you can't. ILMerge will only merge .NET assemblies.
Long answer: yes or maybe. One method is to embed the dll as a resource and extract and load it at runtime. This method works as I've done it before. Another method is to extract the resource into memory and directly call the C++ functions. I know its possible to do it from unmanaged, but haven't attempted it from managed yet.

There is a catch though! Mixed mode assemblies must be loaded from file, it cant be loaded as a byte[].

Hello Joel / All,
Thank you for your responses.
My C++ DLL POST2STK_LIB.dll is a .NET Assembly. It was created and compiled in Visual Studio .NET as a C++ project. The only real difference between it and my C# executable is the DLL contains unmanaged C++ code. But it is still a .NET Assy as best as I can tell. So it would seem there should be a way to use ILMerge to create the single executeable.
For what it's worth, since my dll contains unmanaged code, you can see in my "call" to run ILMerge, I had added the /zeroPeKind switch as my understanding is this is required to attempt to merge the unmanaged code DLL into the executeable. And, if this switch is not used, you get the following compiler error during the ILMerge process stating:
"Performing Post-Build Event...
An exception occurred during merging:
ILMerge.Merge: The assembly 'POST2STK_LIB' is not marked as containing only managed code.
(Consider using the /zeroPeKind option -- but read the documentation first!)"
Thanks again.
Mike

And did it work? AFAIK there is now way to do this, if you however find an answer, be kind enough to share  Thanks

Hi Leppie,
It compiles and ILMerge "works" in so much as it does not give any errors during compile and build of the merged EXE. BUT... what does not "work" is the actual EXE created does not contain the DLL's code embedded within it as described in my original post above. As you say, there may be no way to do this, that is what I'm trying to understand.
Thx.
Mike

Hi,
How can I do to generate a treeview that contains all the Menus (including MenuItems too) of my MDI Form ?
Thanks.
|
|
|
|

There is no way to do it, but manually. You have to enumerate all MenuItems and their children and add them as nodes.

I want to display messagebox to the users in the asp.net webpage. These message box should have the Yes,No,Cancel button in them which returns values for what they click. eg if they click yes then return like 1.

The UI of ASP.NET is handled by the browser most of the time. The window object of the DOM has an alert method: alert("Hello, World"); It has a single button that lets the user close the dialog.

I need to display the confirmation message box not alert. I am using:
Response.Write("window.confirm('Moving next will result in loss of unsaved data!')");
but this doesnt give results. here either you click Ok or Cancel on the massage it does the same operation it does not check what the user clicked.

Ok well you have two choices here - either put up with using Window.Confirm in javascript - which gives you an Ok or Cancel property
or
You can create a web page which you open as a Modal web page (showModalDialog in Javascript) and have that present the information to the user with the three choices - you can then have that return the information to you.

Response.Write("alert('hello world')");

I would like to have a designer property which is a collection of a complex object, a little like the Columns property for the ListView control.
I have looked for articles but to no avail.

I am attempting to add plugin support to a program I wrote.
I have found many articles on Code Project, each showing how you can create objects from an assembly loaded at runtime. This is great, however, my original design made extensive use of inheritance.
Now I'm trying to figure out how I can expose a "parent class" to a plugin.
For example: Button inherits from Surface. Surface needs to be something that can be re-written by plugin developers, so that Button will now inherit the version of Surface in the plugin.
Can this even be done?
-Mike.

I don't think you can do that (or even want to do that; plugins should have very limited set of functionality avalible to them; inserting them into the core of a aplication is not the best choice...)...
But please correct me if I am wrong.

Hello,
This can be done, although it is not an easy road you want to travel.. Here late binding is not enough, but you also need to create code at runtime. I don't know exactly how to do this. Also several problems arise: what if more than one replacement for the surface class is found? What to do with errors that the plugin might cause? Etc.
But I wonder, why do you want to give complete control over your application to some third party?

FillEllipse and FillRectangle don't seem to work with a height or width of 1. That's too bad. I need it to draw a line or pixel when one or both are 1. It seems I have to put extra code in there just for that.
