Porting from unmanaged to managed

[=?Utf-8?B?RGlwZXNoX1NoYXJtYQ==?=]

Hi all,
I have a Dll code written in VC++ having lots of structures, classes etc and
exporting 100s of APIs.
I have to port it to VC.Net to make it managed. How can i port the whole
code to make it managed. I have heard of IJW & wrapper. But please guide me
how can i migrate to VC.Net.

Thanks,
Dipesh

You may want to look the Native and .NET Interoperabilit y section in Visual

Re: Porting from unmanaged to managed

Hi sheng thanks for this link. I am now trying to import my unmanaged dll &
creating a managed wrapper on it as shown below:

[DllImport("C:\\ New Folder\\unmanag ed.dll", EntryPoint = "testfuncti on"
,CallingConvent ion= CallingConventi on::Cdecl)]
String * LonString( const teststructure& v, String * s, uint nb );

public:
String * LonNeuronIdStri ng( const TLonNeuronId& v, String * s, uint nb )
{
return ::NaCppLibLib:: LonNeuronIdStri ng( v, s, nb ); //passing to unmanaged
}
First of all can you please point out the mistake in it. I am no able to
access the structure in VB.Net application. I have included the structure in
namespace.

Thanks.
