This may be the wrong place to ask but where else should I go?
I'm new to .Net and WebServices. However, I'm old in programming MFC/C++ and Java.
I would like to write a WebService (Server) which is NOT running within a IIS (ASP). All I need is a normal managed Windows Service which is listening on a spec. port to publish it's WebService interface. However, there are lots of examples on how to write WebServices using ASP.Net but it seams tobe impossible to accomplish the same with a 'normal' EXE.
Please don't ignore me, let me know your opinion.... 
Cheers

It gave me junk value.....
Any help is appreciated....

Your first post you asked about "wstring to LPCTSTR"
Now you ask about "String to CString" then your code attempts to use a wstring function "c_str()" on a type "String". Assuming you posted your code correctly you should have received a compile error which you did not post.
Perhaps someone else can divine exactly what you are attempting to do and provide you with an answer. I however require accurate specific and complete information regarding this problem before I can begin to help.
Furthermore there is no shortage of articles on the net pertaining to the variety of string types in VC++ and matters of converting between types. If you care to see what I mean just Google [MSDN CString Strings LPCTSTR TCHAR]
I highly recommend studying this subject, it will payoff huge in terms of productivity and will ease your development efforts greatly.

Hi, I am using managed c++ to (try) and get a project that will go through a directory of files and copy them to two directories if the contents are right. Currently the sorting goes alright, but not if I insert the copy call, well, I get this runtime error:
System.IO.IOException: The target directory already exists.
First of all, I'm hoping the directory exists... I have the code write out what it's copying from and to using Console::WriteLine, and I can assure you it is valid and proper. I tried using the overload that includes the boolean and set the boolean to true to allow it to override the file, but it still insists the directory exists.
Has anyone else noticed this and/or got a solution?

I feel like an idiot now 
I changed the code BEFORE the call, but I didn't change the call itself to use the new variable. Now it works fine. PEBKAC right here, I'll tell ya.

Hi,
I have 3 projects:
"Managed C#" calling "C++ Managed Extension (mixed code)" calling "Unmanaged C++ code"
I am trying to debug them using .Net Visual Studio 2003, setting breakpoints on each project. Unfortunately, it is not able to trace down to unmanaged code.
There are some exceptions happening in unmanaged code - and I cant proceed further with the project unless I am able to debug them to know what's going on.
Has anyone come across this situation before??
cheers,
nics

Hi
I am in the process of upgrading an older program written using MCF.
Some parts of the new program use Managed C++ and Windows.Forms (external dll).
Is there an easy way of integrating the two - for example press a .NET button (e.g. of type System::Windows::Forms::ToolBarButton) to open a MFC dialog (of type CDialog)?
I don't want to rewrite everything as Windows.Forms (e.g. convert "CDialog" to "System::Windows::Forms::Form")

We are also trying to do the same and want to reuse the document view architure in one of the complex component. How do we do that? Can we make .NET form as Mainframe/ChildFrame for the views and document? Any pointers will be appreciated.
Thanks.

Have been trying without success to call an managed function from
within an unmanaged class. This would seem to be a basic requirement,
of the dotnet so I am obviously doing something wrong.
Given the class CMyManaged header as:
#pragma once
public __gc class CMyManaged
{
public:
CMyManaged(void);
~CMyManaged(void);
void MyFun(void);
};
and a standard MFC dialog class, I wish to call MyFun() from
within MyMFCDlg().
Now I went about this by declaring a CMyManaged variable m_MyManaged;
in the unmanaged MyMFCDlg() header file. Then in MyMFCDlg.OnInitDialog()
I try to call m_MyManaged.MyFun();
Have tried declaring the managed variable as
gcroot<cmymanaged*> m_MyManaged;
But various means to call MyFun() have all resulted in
compilation errors.
Any help would be appreciated, as the C# dialog box is to limited I
need to continue developing partially in Unmanaged C++.
Many thanks

Post the compiler error messages, otherwise we have to guess.
Obvious things to check:
Do you have properly configured "mixed mode" project settings?
Do you have required #include and import statements?
If you don't know what one or both of those are you need to use MSDN to read about "mixed mode" development.

Hi,
My current Project has the following Requirements:
1. Backup the entire contents of the hard disk including Operating System as a bootable Image.
2. In case of System Failure, user should be able to perform a full system-recovery operation using the Backed up Image of the Hard Disk.
I am new to this concept and request any sort of help on how to proceed with this.
Any help will be greatly appreciated..
Regards

That is generally considered too broad a subject or too vague of a question to receive a meaningful reply in a forum. You could probably write a book chapter or several on a subject of that scope. You might have to do some reading until you have broken down your problem into it's constituent parts. The post small specific questions to obtain help in a forum format.
But, that's just my opinion... I could be wrong.

Okay, I'm a little confused. So, the ANSI / ISO Standard C++ is
a stardard C++ lanugage that targets non .Net platform and
managed C++ is designed by Microsoft that targets .Net platform.
Code that generated by using the ANSI C++ is also called native code or unmanaged code
and code that generated by using Manage C++ is called managed code.
Is that right?

Mostly. However Non ANSI / ISO Win32 C++ code is also considered "native" in discussions of "managed" C++.

Hi all,
I got a problem with Return key in my C++/C# application.
On CView dilalog I put my C# control using managed extension. This C# control has couple
other controls nested. I have problem with RichTextBox control which
is at the bottom of my control hierarchy. It does not process
VK_RETURN key down. So I can not create new line. All other keys work
in RichTextBox. Of course I made it Multiline. I used Spy++ tool to
figure out what is going on. I managed to see that RichTextBox window
receives ON_KEYDOWN message with VK_RETURN. But there is no WM_CHAR message which normally should follow WM_KEYDOWN. As a result no new line is created in RichTextBox.
Tried to catch WM_KEYDOWN in WndProc and onkeydown. But they are hit for all keys except of RETURN
I would greatly appreciate any hints.
Thanks in advance,
Roman

So your C# control is not receiving the VK_RETURN event notification? Try asking in the C# forum.
