Using Multiple Namespaces within same VC++.NET Solution

[kash_VCDotNET]

Hi!
How U Allz?

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
namespace DevilServerInfo {
public __gc class Form1 : public System::Windows::Forms::Form
{
//// some code here........

}
}
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();
}

};
}

Thanx fdor reading such a long Thread.... thanx...
plz reply me soon
