Hi,
i guess you were talking about a managed c++ dll and you would like to add it to a clr project in VS2005.
If so, then you'll have to do the following:
1. go to "Project->References", click on "Add Reference"
2. Browse to your dll and add it
3. reference the namespace of your dll
e.g.
<br />
using namespace MyDllNamespace;<br />
using namespace MyDllNamespace::Net;<br />
...<br />
regards Tobias

In addition to Tobias' info, you can also use #using instead of using "Add Reference" in the Project Properties:
Example:
#using <System.Data.dll>

Hi All
When a client using shared data from remote machine.It is very fast .But with server for same it is taking more time.
The packet transmission is 300 per share data and for server 1500 as per net stat result.
As my packet size is small i disable nagle algorithm also.but not satisfied result.So Please give some guidance.

This is the first time I write a program after learning C++ for 1 week ago.
I use Dev-C++ and I want my program to do function such as:
Ask person to type two number : 1st number ; 2nd number.
such as: 2 ; 5;
and I want my program to get me the sum : 2 + 3 + 4 + 5 = 14
but I try many times and it always gives me : 2 + 5 = 7
This is my code :
using namespace std;
#include <iostream>
long result(long d , long e)
{
if (d >= 1 , d < e)
{
return (result(d + 1,0));
}
else
return (0);
}
int main()
{
long a,b;
long c;
cout << "1st number : ";
cin >> a;
cout << "2nd number : ";
cin >> b;
c = a + result(a , b) + b;
cout << c;
return 0;
}
Can someone tell what 's wrong with my code, and give me a hint to do it.
Thankz.

The result() function is incorrect. Try this:
long result(long d , long e)
{
long r = 0;
int i;
if (d <= e)
{
for (i == d, i <= e, i++)
{
r += i;
}
}
return (r);
}Also change this line:
c = a + result(a , b) + b;
to
c = result(a , b);

By the way thankz for your "fish", hope next time to can show me how to fish.
Yeah!!!

Can anyone tell me how to output data and recieve from a com port on xp/nt in vs2005 managed C++ ?
I have done Parallel i/o before but only on win 9x and never serial.
Thx...

Hi,
if you are using .Net 2 then System::IO::Ports::SerialPort should be the way to go. However, i found this new serial port class quite unreliable (in terms of switching RTS) and used therefore recently the one from windows.h.
for example:
HANDLE _ComPort = CreateFile( ptrComName,....); // create a port
and use
WriteFile(_ComPort, ptrTxFrame, pTxFrameLength,&ulBytesWritten, 0);
ReadFile(_ComPort, ptrRxFrame, 256, &ulBytesWritten, NULL);
to read and write, but with this approach you'll always have to pinpoint your buffers.
pin_ptr<unsigned char> ptrTxFrame = &pTxFrame[0];
best regards Tobias

Thx Bee..
I think that was just what I needed.
I wonder tho, about the reliability.
I don't need rts or dts.. just to have them both stay high.
I am wondering if switching is a problem. Can you elaborate a bit on that part?
If I just set it high and forget it, will it stay?
I am hoping the problem you are talking about is the api not seeing the change state.
So if I set it then it will stay, not wanting to write a watchdog for it.
Thx for the reply..

Right, maybe it did sound a little negative. The reason for my statement was that my application really depends on a very accurate switching time between Request to Send enabled/disabled. For some reason this switching time differs for each switch, 5-15 ms while using the .Net class. Thus I need a constant switching time, which must be less than 10 ms, i'll sometimes run into trouble. With the windows.h method I have never discovered this problem. It displays all the time a continuous 5 ms switch time on my oscilloscope. Probably there is a way to close out this problem but by the time I faced this problem, it was quite critical to go ahead with my project. Therefore I decided to go for the unmanaged option for the time being.
However apart from this odd behaviour this new class is quite comfortable and very straight forward. I'll maybe give it another try after finishing my project.
best regards Tobias

Hi
I too have been looking for a way to access the comm ports using managed code. I'm pretty new to Visual C++ so I need a little more information regarding how to setup and access a com port connected to a USB-Serial adapter. My comm port shows up as COM7 in windows. I need baby steps for opening, configuring and sending and receiving data. I only need to send about 5 or 6 chars but can possibly receive 10 or up to 512 chars from the serial device I'm interfacing with. All the code I've come across on the web doesn't seem to work with Visual C++ 2005 expess Edition.

Looks like you will need to remove "winsock.h" or "winsock2.h" as an included header.

Can anyone tell me how do I display the selected Node name of a treeView in a text box.
I have treeView containing Nodes(e.g. strings), When the user clicks on a particular string in the treeView, that string should get displayed into a textBox. What code do I need to write in treeView_NodeMouseClick event.

Could anyone tell me what I'm doing wrong here:
<code>
// variables defined
private: array<String^>^ m_sAddressList = gcnew array<String^>{"localhost"};
private: int m_nCurrentAddress;
...
// attempting to make a property out of them
public: property array<String^>^ m_psAddressList{
String^ get(){ return array<m_sAddressList>(m_nCurrentAddress);}
}
</code>
I'm getting the following compiler error:
error C3901: 'get': must have return type 'cli::array<Type> ^' c:\documents and settings\john\my documents\programming\visual studio 2005\projects\winbot\winbot\ConnectionOperations.h 53
Any information would be greatly appreciated.
Thanks,
John

The 'get' must return an array to be consistent with how you've defined the property - e.g., return m_sAddressList. It's not clear what you are attempting to return.

Forgive my ingnorance but what is with the '^' chaacter?
The way you are using it is a syntax error in C++.

Hi,
It would be a syntax error in standard c++ but isn't this the (Managed) C++/CLI discussion board? Therefore i would like to point out: "The carat operator (^) (often called a "hat" by C++/CLI folks) indicates that a variable or parameter refers to a reference-type object." Or did i misread your point?

Nope! You told me exactly what I wanted to know. I had a feeling it was something like that, as if C++ did not have enough operators already.

Hi,
I am trying to write a very simple application that mixes MFC with C++ Managed. I have two questions:
1. Is it possible to build the mixed project with the MFC library statically linked. I get some errors of conflict which I don't get when building with dynamically linked.
2. I want to use .NET functions that ask for System::String^ str. When I supply these functions with CString I get error. I read every where that it suppose to work.
CString str = _T("Works");
CString str2 = _T("Doesn't Work");
String ^ stringEx = gcnew String( str ); // OK 
strinEx = str2; // Is not working 
Thanks.

Hi,
You cannot assign an CString object to a string. Every string assignment in .NET creates a new string on the garbage collector and recycles the old one. There is no global defined assignment operator for this available 
You could try to write:
strinEx = gcnew String(str);
This makes no difference to the other assignment.

Hi,
The answer to the first question is probably that it is impossible to do static linking since the code produced for managed application is not native binary code but MSIL.
For different string conversions check following article:
