I'm using VC++ .NET, and I want to dinamicaly create a char * string.
I use the following code, but when I try to make the project, I have a error, exactly a link error not a build error!!!!!
char *c = new char [serialNumber->Length];
error LNK2001: unresolved external symbol "void * __cdecl operator new(unsigned int)" (??2@$$FYAPAXI@Z)
Help me please!!!
Best regards.

Hi,
Please clarify which is more efficient.
using string.Empty or "". If so please explain why is this.
Iam often getting confused on this.
Thanks.

If you are that concerned about performance, you really shouldn't be writing code in .NET. It might take a few nanoseconds more to execute one or the other and unless you've identified this to be bottleneck, I'd suggest you go with the one you feel is intuitive and readable.

Hi,
i am suresh

using string.empty inplace of "" is more efficient.
because it is .net's own function,

Maybe try the "Superior" UNIX way of doing things *sigh*..
Download the source code, try to compile (auto make is always so easy to pick up in just a couple of year for any beginners), fix make/autoconf bug, then fix eventual platform dependant bug...
then.. that's it!

I have developed window application using VS2005 and .NET 2.0 on
Windows XP machine.
I have made setup project and deployed my application to Windows
2000,Windows XP and Windows 98 machine. (All installations are
fresh)
Application works well in Windows XP & 2000 but it is not
working in Windows 98.
There are two errors
1 Error)
Retrieving the COM Class Factory for componen with CLSID failed
with HRESULT: 0x8004015 (Class not registered
(REGDB_E_CLASSNOTREG))
System.Runtime.Interopservices.COMException
This error happens when I use System.Management.Objectsearcher
to read processor serial number using Select * from
Win32_Processor.
2 Error)
Logon Failed
Error in file
CrystalDecisions.CrystalReports.Enging.LogonException:Logon
failed. Unable to connect: incorrect log on parameters
System.Runtime.Interopservices.COMException
This error happens when I use Crystal Report and load it. I am
not usding db connection. I am using typed dataset so need of
dbconnection.
I have noted one thing comman in the both error is that
Exception is of System.Runtime.Interopservices.COMException..
so is there any problem in windows 98 when we use .net
namespaces which wrappers COM??
Some one please sort out my errors
Thanks

This means that your trying to use WMI on a machine that either doesn't have it or the installation is screwed up. This has nothing to do with the .NET Framework though.
Windows 98 doesn't come with WMI installed. Download the core components here[^].
Also, keep in mind that not everything in the .NET Framework is supported on Windows 98. No, there is no list spelling out what works and what doesn't.

 Hi,
My application in vb.net calls its reports (CR) via the report viewer class. The report gets loaded but the time for calling the report is too much. Once in the cache it does not take much time. Is there anyway by which it is possible to load the reports faster? Thnx in advance for helping me out.
Bye TC

Hello,
I'm thinking of writing a program that contains a messaging system like MSN Messenger, with all communication going via a server on the internet. I went looking for examples and I did found some. However, I don't know which technique I should use. A webservice would be nice for the serverside, since I wouldn't need a dedicated server or something like that to run a 'standard' server application. But I didn't manage to determine if a webservice will fit all my needs, like events (an event fired on the server must trigger a function on the client side).
The most important thing is a speak function, so that two (maybe even more) connected clients can talk with each other (not P2P but also via the server). I really don't know if I can realize that with a webservice. Maybe someone could point me in the right direction? Also, I don't know yet how to realize such a 'speak' function. I didn't find anything on that subject (I only read something about an embedded feature in DirectX9 for sending audio over the web, but I prefer not to use DX).
Any help is much appreciated!
Thank you very much in advance.

Yes, you can install as many .NET frameworks as you like.

I read “Implement a Microsoft Word-like Object Model for Your .NET Framework Application” found at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/netwinforms.asp[^] and wondered if anyone has been able to create a .NET application that can act as an OLE Automation Server. By that I mean, I can insert an object, say an Excel worksheet, in my Word document and work with the spreadsheet inside Word. The spreadsheet is embedded in the Word document.
My question: Is it possible to create a .NET application that can be embedded in another application like Word? If so, does anyone have any code to show how this would be done?

Compile it with a managed c++ wrapper ( the amount of C that is not valid C++ is almost non-existant, unless it's C99 ). Or, write it into a COM object or plain DLL and interop that way.

I'm thinking about making a project in java because of portability but is there any evidence that the .net framework will be truly portable, like would anyone come out with a framework for other platforms, are there any attempts, i still haven't started the project that much and I would like to use c# better but if the supposed .net framework portability feature is just a theory then i will sadly have to use java

Mono runs on Linux, and Java is crap. What's the point of having a BAD UI on more than one platform ? Surely Lotus Notes taught us that ?
However, Mono does not have a UI component AFAIK. If I wanted to write a portable app, I'd write the business logic in C++ and recode the UI natively on each platform, so that it took advantage of the features of each platform.

True. But, I've used J2EE, and I found it to be crap. Sorry.
