Microsoft is attempting to keep C++/CLI close to the standard as possible. Thus, the concept behind the "partial" keyword goes against the current C++ standard, and Microsoft will not make any attempt to support the "partial" class concept. By the way, the upcoming C++ standard will not support this concept also.

I cannot see how ^ or finalizers are closer to C++ standard than the partial keyword would be. The influence of partial to the compiler is perhaps much smaller than this of already introduced keywords, isn't it?
BTW, you may want to take a look at "C++ divided by CLI"[^] by Dominic Connor.

The "^" and finalizers have a swallow impact on the overall behavior of C++. However, partial classes impact on how the compiler works and the behavior of OOP in general. The problem is how would you create partial classes following C++ rules. IMHO, combining partial classes is similar to public inheritance without a base or derived class. That concept is very alien to C++.

OK then, how about getting some control over the formatting of generated code? Any chance?
|
|

Unfortunately, I don't think we have any options unless you format the code afterwards, and, thus, breaking any hope of creating more generated code.

partial classes are an attempt to catch up with C++. You can split a class into multiple cpp files now, managed, or otherwise.

Yes, you can split a C++ class among multiple C++ files. However, a "partial" class in C# and VB acts more like a namespace since one or more partial classes combine fields and function members in one set. In contrast, you must a least declare a member function in a C++ class declaration, and define the member functions in the class declaration or someplace else.

The real difference is, the C++ has a header file, and C# and VB.NET do not. Once you have a header file, I don't see how the multiple C++ cpp files behave any different, except that in the absence of a header file, you can keep adding files to extend a partial class, without having to maintain a central interface definition.

That's the difference!

Well, .cpp is not an issue. The Designer smashes the one and only .h file of a control or a form. Maybe my coding standard is inconsistent with Microsoft's, but those intrusions make a real mess there. Either should they be placed in a separate file (using an extension similar to the C# partial keyword), or Designer should provide a powerful configuration facility for code generation, where I should define my preferred style in the form of some template. Adding such functionality shouldn't be a real problem.
May you have any XAML/C++ interop experience? Are these issues still present in Orcas? I haven't had a chance to play with it yet.

C++/CLI is not supported on an Unix OS. You will have better luck asking this question in the Visual C++ forum. However, please note that the Visual C++ forum is a Windows OS based forum.

Hi,
I'm pretty new to programming in C++ (got some PHP/MYSQL exp.).
But I'm trying to make a program now(not important), but I want to check if they registerd their version trough a mysql database.
This is (empty) function that i'm going to use
int user_check(string user_reg, string user_pass, string account_name)<br />
{<br />
if(var4 != "yes")<br />
{<br />
user_checked = 1;<br />
}<br />
return user_checked;<br />
}
So what I want to know is how to make a connection with a database, then get the results from a table(ex. members).
please help me out
(If you include files, give me (a) link(s) where I can get them all)
I'm using Dev-C++ to compile
Thanks in advance

Then you are, by definition, not using C++/CLI.
There is no database support in C++, it's all provided by external libraries. Any answers you get in the Visual C++ forum, are likely to be Microsoft Visual Studio centric. You could try there, it's better than asking here, but I'm not confident. Have you tried google ?

Yes and it brought me to this post
http://www.codeproject.com/database/mysqlwrap.asp but when I try to compile it always gives the error that mysql.h isn't included. Even when it is in the main program. I copied the whole include map of a mysqlserver (4.1) to the same map where mysqlplus.h is :-/

Hi everybody.
I wanna write an application which has a database created using SQL-Server2000.
In this app I need to have a beautiful graphical user interface and on the other hand have to be able to work with the data tables in an mfc application that is created with vc 2003.(not .net)
what do you suggest?
i think a web service would help if so, can i write it with .net2.0 using c# and asp.net and use the web service with mfc 1.1?
please help me!!!!!!

Yes, I can see how you may have chosen the C# forum, the C++ forum, the XML forum, the webdev forum or the SQL forum. The C++/CLI forum is about the only one that doesn't fit :P

Hello,
I am programing in c++ but I do not use any namespaces. I would like to learn and use it to be more effective. Where can I found some tutorial or information to begin to understand the real advantage to using name space.
Thank you

Hi all,
I need to read a file having rows like
DATA[DELIM]DATA[DELIM]DATA[END]
DATA[DELIM]DATA[DELIM]DATA[END]
DATA[DELIM]DATA[DELIM]DATA[END]
Is there any ANSI C compliant free source available which can read a text file and can read data between [DELIM] given the index?
thank you
Aamir

If there is, it won't be C++/CLI. You're in the wrong forum, even if you were asking for ANSI C++. ANSI C file handling is nasty, if you're doing C++, you should look for a C++ solution. Either way, this forum is for C++/CLI questions. Try the visual C++ forum

This is really a 2 in 1 question. Normally (read: never before) I don't handle this aspect of an application, being more involved in the mathematical routines, but this time I am responsible for some of the UI. This includes making an attractive UI (having a progress bar) and a responsive UI (having multiple threads).
I have a Windows form application built on (let's call it) Form1. On that form there is a progress bar, progressBar1. I also have a class (let's call it CMyBigCalculation). Inside this class there is a calculation whose time increases almost exponentially (but not quite). Thus I would like to report the progress of the calculation on the progressBar of Form1. But I am not sure how to expose the percentage progress of the calculation (it's deep within the class). The alternative to somehow exposing the progress (which would be difficult), I suppose, would be to create the progress bar from within the class, but I'm a little hazy on creating controls like this. For example, from within the class, how do I create the progress bar on Form1? If I'm out to lunch here, is there a better solution?
Secondly, I would also like to multi-thread this because during the long calculation the app could easily become unresponsive. Again, since this calculation is embedded within the class should I open the new thread from the class or from the main app (i.e. from the code contained in Form1)?
Any help would be greatly appreciated as I'm a little out of my range of expertise.
Windows with no internet connection is safe, but that's not what Windows was built for.
