Get stock-setup infos from a MachineGroup

[TNunes]

Hi,

i need help,

 

i use NetHook (NETHook2_0.dll) with MicrosoftVisual C# 2008

and the MasterCam X3.

 

i would like get infos about stock-setup in a MachineGroup

i can get "JobSetupMaterial", "JobSetupStockOrigin", "JobSetupStockSize"

but i don't find how to get : the type of shape,

if the shape is file ,the path of the "stl" file, ...

 

thanks,

Thomas

TNunes,

 

Not everything is available via a NETHook.

You could get more details using CHook methods.

*You could create a CHook just to retrieve this specific information and pass it back to your NETHook. (using P/Invoke Interop)

It's not that difficult to utilize a 'CHook' type DLL functions via a NETHook.

Matter of fact, the Zip2Go utility in Mastercam -

All the UI is a NETHook (Zip2Go.DLL), but all the data gathering is done via calls into a Chook (Z2GData.DLL).

 

PInvoke Interop - Mastercam

Thanks Roger,

 

In fact i would like to get the infos in the struct "group_pg3"

which is in "op_group_info",

which is in "op_group",

 

And in the MCCore.dll i found the function :

op_group* TpGrpList::GroupByName(char *Name)

With the EntryPoint =

"?GroupByName@TpGrpList@@QAEPAU_op_group@@PAD@Z".

 

So i try that in my C# code :

code:

---

[DllImport("MCCore.dll", EntryPoint ="?GroupByName@TpGrpList@@QAEPAU_op_group@@PAD@Z")]

private extern static IntPtr GroupByName(ref string Name);

---

I'M NOT SURE OF THE PARAMATER(ref string Name) AND THE RETURN(IntPtr) //////////////

code:

---

private int GetStockInfo(string NameMachine)

{

IntPtr iIntPtr = IntPtr.Zero;

try

{

MessageBox.Show(NameMachine, "NameMachine"); //for DEBUG

iIntPtr = GroupByName(ref NameMachine);

MessageBox.Show(NameMachine, "NameMachine"); //for DEBUG

MessageBox.Show(iIntPtr.ToString(),"IntPtr"); //for DEBUG

...

...

}

catch (Exception e)

{

(...)

}

finally

{

//clean up memory

if (iIntPtr != IntPtr.Zero)

Marshal.FreeHGlobal(iIntPtr);

}

}

---

But finally i get the three messages box :

DMU_50_EVOLUTION //It's my Machine : OK

DMU_50_EVOLUTION //It's my Machine : OK

0 //Null Pointer (i don't understand)

 

Can you please give more informations about my problems ?

Does the EntryPoint change with the version of the dll ?

And to get the infos in group_pg3 with the "Pointer" ?

do i must define the structure like this :

code:

---

[structLayout(LayoutKind.Sequential)]

public struct _op_group

{

public int grp_idn;

[MarshalAs(UnmanagedType.ByValArray, SizeConst = MAX_GROUP_NAME + 1)]

public char[] name;

public int parent_grp_idn;

(...)

public op_group_info ogi;

}

---

AND

code:

---

public struct op_group_info

{

(...)

[MarshalAs(UnmanagedType.Struct)]

public group_pg3 pg3;

[MarshalAs(UnmanagedType.Struct)]

public group_pg4 pg4;

} ;

---

AND ETC... ?

 

Thanks for your answers!

I try to create a CHook wich retrieve this specific information and pass it back to my NETHook as well.

It's may be easier.

 

thanks !

Finaly,

 

Create a CHook,which is managed by a NETHook it's the best way to get more information about the MasterCam's object.

 

Thanks to Roger Martin for his help.
