What I'm trying to do here is access a Windows server using Windows API function wnetaddconnection. I got my program to use the function but it kept getting the error 487 when connecting. Which is "Attempt to access invalid address." Now, I'm pretty sure I got the address correct. The same parameters were used with another Program written in powerbuilder and also uses the Windows API.

This is how the function looks like:

DWORD WNetAddConnection2( __in LPNETRESOURCE lpNetResource, __in LPCTSTR lpPassword, __in LPCTSTR lpUsername, __in DWORD dwFlags );

So I created my own Structure in Java:

public class NETRESOURCE extends Structure{ public long dwScope; public long dwType; public long dwDisplayType; public long dwUsage; public String lpLocalName; public String lpRemoteName; public String lpComment; public String lpProvider; }

The C looked like this:

typedef struct _NETRESOURCE { DWORD dwScope; DWORD dwType; DWORD dwDisplayType; DWORD dwUsage; LPTSTR lpLocalName; LPTSTR lpRemoteName; LPTSTR lpComment; LPTSTR lpProvider; } NETRESOURCE;

Then I called the function like this:

MPR mpr = MPR.INSTANCE; NETRESOURCE lp = new NETRESOURCE(); lp.dwType=0; lp.lpLocalName=null; lp.lpProvider=null; lp.lpRemoteName="\\\\valid\\address\\pramis"; int i = mpr.WNetAddConnection2A(lp, "password", "username", 0);

Any help would be appreciated. Please.
