That's simply not true!
Microsoft .NET Framework can be installed on the following OS (hence applications will run on these operating systems):
Microsoft Windows® 98
Microsoft Windows NT® 4.0 (SP 6a required)
Microsoft Windows Millennium Edition (Windows Me)
Microsoft Windows 2000 (SP2 Recommended)
Microsoft Windows XP Professional
Microsoft Windows XP Home Edition
HOWEVER! ASP.NET is NOT supported on anything below Windows 2000 ..... and the Visual Studio .NET 2003 will NOT install on anything below Windows 2000. But ALL compiled applications will run happily on anything above and including Windows 98

I can vouch for that; I've run a .NET program fine on a Win98SE computer.

I'm programming VB.NET and my application has an open ODBC connection to a remote database (MySQL) server. I'm using the .NET framework with data adapters, data sets etc.
Now, my application needs to some how be notified when the database has been changed (for example by another client running on another computer). Some kind of notification from the server to the client upon database change. There must be some way to do that, right?
I hope there is someone who can help me with this. Thanks!

I've never used MySQL so I don't know if it will work. Does MySQL support the concept of Triggers? If so, it may be possible to write one that will notify the client somehow.

Hi,
if i just buy a VC++.Net but not the whole Visual Studio.Net
package, can I still use it to develop software for Pocket PC 2003/Smartphone by using the compact framework extension ?
and can I develop software on PocketPC/Smartphone by using
C# ?
Thanks

Hi all,
I have three questions,
1. What are the limitation of C# compared to C++.net ?
2. will MFC in VC++ be obsolete in future ?
3. Do we need to obsfucate the code in C++.net as in C# for
protecting the reverse engineering of software code ?
Thanks

C#'s not C++, however both are compiled to MSIL which is JIT compiled to native code (See Compiling to MSIL.) C++, however enables you to use easily use the full power of native code, pointers, etc. within managed code. However, C# is also powerful in that it can leverage native code through calls to Unmanaged Code and also can access pointers with some caveats (see C# Language Specification Appendix A Unsafe code).) C++ also allows for templates and the STL for the "behind the scenes" code. C# won't have anything similar until Generics are officially released as part of the language specification.

No. MFC is quite mature [and so is ATL!] for robust, straight Win32 applications, and will be part of VC++ for the forseeable future.

For native C/C++, you can just strip out the symbols. But for C++.NET, since it is compiled to MSIL (as are any languages compiled to MSIL such as C#, VB.NET, COBOL.NET, et al.) you must obfuscate if you wish to hinder reverse-engineering.

Hello
I have a .Net Dll
MagicLibrary.dll
who can say how to use a badly named namespace
Crownwood.Magic.Controls
which is badly named
Crownwo╗$d.Magic.Library
I think it is locked but i have a software that uses this
component without anymore files in runtime
but i don't know anything about design time.
Is there anybody who can use or disassemble this library
for me?

The magic library used to be freely usable.
Now it is not. The runtime can be used by applications which were built using the licensed version, but the design time is locked to the end user without a license.
|
|
|
|
|
FYI: The license disallows dissasembly (it's illegal,) like in most other commercial software licenses.

I was looking through the docs for what type of sockets I can create with the System.Net.Sockets.Socket class and I saw "RDM" - Reliable Data Messaging. To me this seems like quite a nice swap-in alternative to UDP in some cases [when speed isnt terribly important, but there's no need to create a connection then destroy it like TCP would require]
I tried to create it with the address family InterNetwork [IP v4.. normal internet] and Undefined protocol-type... since there's nothing there that looks like it would be RDM.
When it tried to create the socket, it threw an exception that the address family doesnt support RDM.
Now... for one I'd like to have RDM for Internetwork..... but in any case.. does anyone know where I can find any info about the different socket-type/protocol combinations with their supporting address families.
Thanks.

I'd like to set a "Special Build" property/attribute in the Assembly of my project (or in a resource file) -- something that gets compiled in.
I've looked around the net for this and it's really not clear to me.
I'm using Visual Studio.NET 1.0 and my App is standard C#. I've actually got two flavors of the app (one command line and one GUI) and I need to set the "Special Build" string differently for each app (E.g., I don't want to do it in code, I just want to set the values differently in either resource files or in the AssemblyInfo.cs file).
Thanks for any tips!

I think you need to write an .rc file, compile it with rc.exe, then use the /win32res switch to compile it into the assembly.

I am running .NET remoting server hosted in IIS, the function is collecting all the logged in user account, but after it got the first one, I had "ChannelServices" is out of scope exception. Does any one know what caused it?

Greetings CodeProject Gurus. I have an interesting problem that I hope you can advise me on.
I need to design an assembly thatacts as a hardware interface for something. The assembly will attach to a single Comm port (I'm using JH.CommBase for that). The assembly must expose three different interfaces. Each interface may be accessed by a different application, through native .NET or perhaps via COM Interop at run-time.
So here is my problem: when the three different applications launch and create instances of the interfaces, three seperate copies of my assembly get loaded. Each instance tries to open the single Comm port and naturally only two of them succeed.
Clearly, I have an architectural design issue here. I wonder how you guys would deal with this issue? Is there a way to design an assembly that implements the Singleton pattern, but _systemwide_ not just _application wide_? Or maybe a radically different solution?
Regards,
Tim.

Could you design your system so that the access to the COM port was through a Windows Service. They you could have your three applications safely communicate with one windows service which, in-turn, commuicates with the one COM port.
Does this help?

This is an option I have considered, but I'm not sure how an application communicates with a service. I guess I could RTFM  Not sure how I would support W98 systems though.
Another idea I have considered is use of MSMQ, or maybe .NET Remoting. Both of these techniques might have other beneficial side-effects for my projects. I guess I was just hoping there is someone out there who has been in a similar situation and could tell me how they solved it.
Thanks for the suggestion,
Regards,
Tim

Yes, just create a service and expose an interface using .net remoting, that interface should not be the singleton.
i.e. you can create it as WellKnownObjectMode.Singleton but this will backfire. It is better to make the singleton a seperate class from the remoting object:
The reason for this is if your object has not been used for a long time then remoting may create a new instance, and since this is done by serialization you can end up with multiple instances!
alternativly see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemruntimeserializationiserializableclasstopic.asp[^] for info on how to handle this issue.
