C-hook and operation groups

[markov]

How do I access operation groups from a C-hook? Namely, I want to rename existing groups and create new groups.

 

Thanks

see m_db.h

list_grp_add_empty - adds empty group.

list_grp_delete_name - deletes group by name.

 

You can't access groups directly since CNC software doesn't make the group list pointer directly available in the chook developement kit. One of several usefull items that seem to be absent.

 

You can read group_list structures from a file using the grplib_list function. You can then match up the grp_idn in the group_list structure and the operation structure.

Thanks, I shall check it again when I get to the right computer. But don't those functions need a list of groups as an input argument? I may be wrong here, I do not remember what exactly I saw when I was browsing through the header files the other day.

oops my bad.

 

use delete_group_and_subs instead, it looks like it only needs a name.

 

list_grp_add_empty doesn't need a list so its fine.

Hi,

 

there is an undocumented variable called group_list_ptr

 

You can get the address with GetModuleHandle() and GetProcAddress().

 

Hope this helps.

 

code:

---

.data

szGroupListPtr db "group_list_ptr",0

 

 

.data?

GrpListPtr dd ?

hModule dd ?

 

 

.code

invoke GetModuleHandle, NULL

mov hModule, eax

 

;get group_list_ptr

invoke GetProcAddress, hModule, addr szGroupListPtr

mov GrpListPtr, eax

Markov,

 

I had the same issue as yours with Groups one year ago. Unfortunatly MasterCAM API doesn't help so much on that. I soled my problem using the STL (Vector , Deque ...)

 

Bryan,

How are you doing ?
