Dll Import with entry point

[Mito0602]

Heyy,

i know that using google.de helps with many problems. Unfortunately i am not able to get this one solved:

I have a .dll and a C# source File, nothing else.

My problem is that i can't transform the C# code in an executable

Following is the C# Code:

[DllImport("SomeonesApi.dll", EntryPoint="RegisterUser")]
    public static extern uint RegisterMe(
            byte   hUsernumber,                // Requested Usernumber (in hex)
            string  Username);                    // Name of the user

[DllImport("SomeonesApi.dll", EntryPoint="RegisterUser")]
    public static extern uint RegisterMe(
            byte   hUsernumber,                // Requested Usernumber (in hex)
            string  Username);                    // Name of the user

To copy to clipboard, switch view to plain text mode 

The solution i've seen is via QLibrary.

QLibrary lib("C:/Windows/system32/SomeonesApi.dll");
    lib.load();
    bool successfully_loaded =lib.isLoaded();
    typedef unsigned int (*RegisterMe) (unsigned char,std::string);
    RegisterMe newUser = new RegisterMe(0x01,"User1");
    RegisterMe returnvalue = (newUser )lib.resolve("RegisterUser");

QLibrary lib("C:/Windows/system32/SomeonesApi.dll");
    lib.load();
    bool successfully_loaded =lib.isLoaded();
    typedef unsigned int (*RegisterMe) (unsigned char,std::string);
    RegisterMe newUser = new RegisterMe(0x01,"User1");
    RegisterMe returnvalue = (newUser )lib.resolve("RegisterUser");

Can someone tell me what i've done wrong? Is there another (better) way to get this c# function transformed?

Thanks in advance

I think i got it working ... :

QLibrary lib("C:/Windows/system32/SomeonesApi.dll");
lib.load();
bool successfully_loaded =lib.isLoaded();
typedef unsigned int (*RegisterMe) (unsigned char,std::string);
//RegisterMe newUser = new RegisterMe(0x01,"User1"); this line was the wrong one
RegisterMe newUser = (RegisterMe )lib.resolve("RegisterUser");
if (newUser) 
{
     newUser(0x01,"User1");
     return 0;
}
else return -1;

QLibrary lib("C:/Windows/system32/SomeonesApi.dll");
lib.load();
bool successfully_loaded =lib.isLoaded();
typedef unsigned int (*RegisterMe) (unsigned char,std::string);
//RegisterMe newUser = new RegisterMe(0x01,"User1"); this line was the wrong one
RegisterMe newUser = (RegisterMe )lib.resolve("RegisterUser");
if (newUser) 
{
     newUser(0x01,"User1");
     return 0;
}
else return -1;
