X2 crashes after storing note from Net Hook

[CaKiwi]

The following code to store a note works fine in X SP2 but X2 crashes shortly after the routine is exited

 

code:

---

{

ent entity;

int len;

int lev;

char txt[256];

char *cptr;

ulong mtid;

DB_LIST_ENT_PTR ptr;

attributes new_attrib;

MC_BOOL succf;

 

lev = 3987;

strcpy(txt, "Test Note");

len = strlen(txt) + 1;

 

InitNOTE(&entity);

 

cptr = (char *) mTableAlloc(len, &mtid); /* allocate table item */

entity.u.n.mtid = mtid; /* assign memory table */

strcpy(cptr, txt); /* copy string */

 

/* Create new note */

new_attrib.width = 0;

new_attrib.style = 0;

new_attrib.pen = 0;

new_attrib.pstyle = 0;

new_attrib.filler = 0;

 

store_ent (&entity, &ptr, 0, 0, lev, new_attrib, &succf);

}

---

A message window pops up with the error

 

"Mastercam X2 has encountered a problem and needs to close"

 

The Net Hook is written in C# and it calls this routine in a dll written in C. It was compiled in X and is being run under X2.

 

Any help greatly appreciated.

CaKiwi,

 

Calling your C++ routine (with no parameters, since you did not show those) via a P/Invoke call from a NETHook DLL (both build for X2, using VS2005) worked fine for me.

This could be the problem.

Q? The NETHOOK and/or CHook was "compiled for X" ?

[CaKiwi]

Thanks for the response, Roger.

 

By "compiled in X" I meant linked using the libraries from the X SDK. Do I need to download and use the X2 SDK? If it it linked with the X2 libraries will it run under X? Also, I am using VS2003. Do I need to use VS2005?

 

Thanks again for the help

CaKiwi, using "wrong" Mastercam SDK and compiler can cause unpredictable behaviour - look at this problem.

 

In short, with the mismatched Mastercam SDK, those functions may fail. With the mismatched compiler, C/C++ runtime calls may fail.

It depends, sometimes you can get away with it - but don't count on it.

For X2 development, you want VS2005

[CaKiwi]

Thanks again for the responses.

 

One more question: can I use VS2005 for X?

[markov]

Only if you want to assume the risk! See my post above, you may have problems with C/C++ runtime calls. See also the other thread (link is in the post) where I suggested a way to work around it (I have not tried the trick myself).

I am back working on this problem. I am now using the MasterCAM X2 SDK and VS 2005. MasterCAM no longer crashes when the store_note function is called but the note does not get stored. This code works fine in MasterCAM X using VS 2003. Any suggestions greatly appreciated.

CaKiwi,

Did you get my email about this?
