get_user_type

[rm_titus]

Hello guys,

 

Does somebody knows in which DLL the entry point get_user_type is located ?

 

Thanks a lot !

In your CHook you can just do this to get access to this function ->

 

#include chksim_CH.h // This .h is part of the CHook SDK

Thanks Roger !

 

I'm actually doing a C# application and I need to import that function.

Hi guys,

 

I'm using finally

code:

---

[DllImport("SimAccess.dll", EntryPoint = "?get_hasp_info@@YAXDPAUmcSimInfo@@@Z")]

public extern static void get_hasp_info(sbyte countLicenses, mcSimInfo* sim);

 

with

 

[structLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]

public struct mcSimInfo

{

public sbyte netHasp;

public sbyte netHaspNetwork;

public long serialNumber;

public short timeLimitOK;

public sbyte timed;

public short daysLeft;

public ushort timedStartDate;

public ushort timedEndDate;

public short userType;

public int nMillSeatsLicensed;

public int nMillSeatsLeft;

public int nLatheSeatsLicensed;

public int nLatheSeatsLeft;

public int nWireSeatsLicensed;

public int nWireSeatsLeft;

public int nDesignSeatsLicensed;

public int nDesignSeatsLeft;

public int nRouterSeatsLicensed;

public int nRouterSeatsLeft;

public sbyte maintenance;

public short maintDaysLeft;

public short maintDateOK;

public ushort maintExpirationDate;

}

You want just the user 'type'

-or-

More detailed SIM info?

 

BTW...

get_user_type()

Is in the mastercam.exe

Thanks a lot Roger !

 

Well, initially, I wanted just userType but having more details is better

 

Now I'm trying to implement get_user_type() into a standalone application, with this declaration

code:

---

[DllImport("mastercam.exe", EntryPoint = "?get_user_type@@YAFXZ")]

public extern static short get_user_type();

---

but I'm getting an AccessViolationException when calling.

 

Anything wrong in my declaration ?

 

Thanks

I created a simple (C#) Windows Forms Application (with a textbox and an OK button) and this appeared to work for me ->

 

code:

---

  System.Runtime.InteropServices.DllImport("mastercam.exe", EntryPoint = "?get_user_type@@YAFXZ")]        

public static extern short get_user_type();

 

private void buttonOK_Click(object sender, EventArgs e)

{

short utype = get_user_type();

this.textBox1.Text = utype.ToString();

}

---

Of course the App's .EXE must be in the same folder as mastercam.exe using the DllImport declaration shown above.

Thanks Roger for your assistance but still getting AccessViolationException and don't understand why.

 

My mastercam's file version is 11.2.3.22

If I'm using Mastercam.EXE located into sdkdebug directory, everything works great.

 

Hopping this help to understand my meaning...

You can get AccessViolationException if you're mixing Release & Debug code.

If seen this happen if my NETHook) app is a Debug build and Mastercam is a Release build.

 

If you could explain in detail exactly what you're trying to do, that may help.

 

'Stand-alone' application.

Are you trying to get this info without having Mastercam running?

I would not be surprised if that did not work.

[rm_titus]

Thanks Roger !!

 

I'm not mixing Release and Debug code, it was just a quick test to see what's happening when the library mastercam.exe is the one in sdkdebug folder.

 

I'm doing a C# Windows Form Application straightforward, having a textbox and a button on it so it's not a NET-Hook and Mastercam is not running. I need to know the type of the user without having to open Mastercam.

 

I keep getting that exception whenever McamX2-MR2mastercam.exe is used.

 

Thanks,

Using a simple (standalone) C# Windows Form Application that has a textbox and a button on it.

Mastercam is not running...

 

To read the data on the HASP we can call the exported GetSimInfo function in SimAccess.dll.

 

Of course SimAccess.dll is 'unmanaged' code.

So we use P/Invoke Interop to do the calling from our 'managed' (C#) App to the 'unmanaged' SimAccess.dll

 

code:

---

       using System.Runtime.InteropServices; 

 

// Must layout the data structure that ‘GetSimInfo’ is expecting

// (This must add up to ‘112’ bytes)

[structLayout(LayoutKind.Sequential)]

public struct mcSimInfo

{

[MarshalAs(UnmanagedType.Bool)]

public byte netHasp; // bool

public byte netHaspNetwork; // bool

public int serialNumber;

public int timeLimitOK;

public byte timed; // bool

public int daysLeft;

 

[MarshalAs(System.Runtime.InteropServices.UnmanagedType.ByValArray, SizeConst = 12)]

public byte[] timedStartDate; // char

 

[MarshalAs(System.Runtime.InteropServices.UnmanagedType.ByValArray, SizeConst = 12)]

public byte[] timedEndDate; // char

 

public int userType;

public int nMillSeatsLicensed;

public int nMillSeatsLeft;

public int nLatheSeatsLicensed;

public int nLatheSeatsLeft;

public int nWireSeatsLicensed;

public int nWireSeatsLeft;

public int nDesignSeatsLicensed;

public int nDesignSeatsLeft;

public int nRouterSeatsLicensed;

public int nRouterSeatsLeft;

public byte maintenance; // bool

public int maintDaysLeft;

public byte maintDateOK; // bool

 

[MarshalAs(System.Runtime.InteropServices.UnmanagedType.ByValArray, SizeConst = 12)]

public byte[] maintExpirationDate; // char

}

 

 

// Declare the DllImport for the function we wish to call in the external DLL

[DllImport("simaccess.dll", EntryPoint = "GetSimInfo")]

public extern static void GetSimInfo(bool countLicenses,

[MarshalAs(UnmanagedType.Struct)]

ref mcSimInfo simInfo);

 

 

/// <summary>

/// Read the HASP

/// via the 'GetSimInfo' function in SimAccess.dll

/// and return the ‘usertype’ data

/// </summary>

private int ReadSimInfo()

{

bool countLicenses = false;

mcSimInfo simInfo = new mcSimInfo();

// int size = Marshal.SizeOf(simInfo); // Diagnostics - to check the struct size

GetSimInfo(countLicenses, ref simInfo);

return simInfo.userType;

}

 

 

private void buttonOK_Click(object sender, EventArgs e)

{

int userType = ReadSimInfo();

this.textBox1.Text = userType.ToString();

}

That's GREAT!!

 

I was using get_hasp_info() function but your code is MUCH better !!

 

Thanks a lot Roger
