Hi!
Plz anybody can give me idea about using Different My-own-created Namespaces
in a single VC++.NET solution
And If these namspaces are in Different forms (MFC, ATL and .NET)....

Background: I m creating my academic project on Network Monitoring Control I
have done some phases of my project,
like Basic Server Informations, Server CPU Informations, Performance
monitoring of Memory and CPU. but if i merge them all in a single solution,
and calling one namespace in others. it doesn't recognize the calling
namespace.....

sum code chunk.... will explain u better
using namespace DevilServerInfo;

namespace DevilsoftNMC

{

public__gcclass frmServerPerformance : public System::Windows::Forms::Form

{

public:

frmServerPerformance(void)

{

InitializeComponent();

InitEvent(); // My own created Event Caller

}

public void InitServer(void ){
DevilServerInfo::CServerInfo *cf = new DevilServerInfo::CServerInfo();
}

};
}
What is wrong in this code..... plz tell me

Thanx fdor reading such a long Thread.... thanx...
