Adding Custom Operation to Operation Manager

[Zoffen]

is it possible to add a custom operation into the operation manager?

one that mimiks the looks of the mastercam operations but displays the stuff i want in the treeview.

Also, is there a way to modify the treeview contents for each operation. Could i add custom properties in there?

thanks!

Yes it is. It's called a CHook Operation that has it's own "ID"

operation->opcode = TP_CHOOK

When an operation has this opcode, you can now give Mastercam custom(exported) callback functions in your DLL to call

when the operation's tree branches are selected.

 

See the prm_chook structure in AssocTyp_ch.h ->

/// chook operation
typedef struct
{
char opmgr_txt[60];    ///< operation description to display in the operation mgr
char chook_name[40];   ///< source chook name (no prefix path).  If "" (null string), call as dll's
char opmgr_prm[20];    ///< chook's function or dll to call when op's parameters are selected in the Operation Manager
char opmgr_tool[20];   ///< chook's function or dll to call when op's tool is selected in the Operation Manager
char opmgr_geom[20];   ///< chook's function or dll to call when op's geometry is selected in the Operation Manager
char opmgr_nciL[20];   ///< chook's function or dll to call when op's nci is selected in the Operation Manager with the left mouse button
char regen_nci[20];    ///< chook's function or dll to call to regenerate op's nci section
MC_BYTE params[470];   ///< chook operations parameters
char opmgr_nciR[20];   ///< chook's function or dll to call when op's nci is selected in the Operation Manager with the right mouse button
MC_BOOL OkFilter;      ///< TRUE - operation ok to be filtered
MC_BOOL OkTpEditor;    ///< TRUE - operation ok to be toolpath edited
MC_BYTE more_params[147]; ///< even more parameters, in case 470 bytes is not enough
MC_BYTE pad[297];	///< Memory padding
} prm_chook;

thanks!

 

not that this is a mastercam question but can you call .net code from a chook?

basically have the operation in c++ but have all my GUI stuff in c#.

can you call .net code from a chook?

Calling from "unmanaged" code to "managed" code is possible.

 

Either via COM (yuck!) ->

Or using C++/CLI were you can coexist C++/MFC with "managed" .NET in the same assembly.

*Note ->

.NET is this case is not "directly" C# (or VB),

but of course once you're on the .NET side of the fence, it is possible to call methods in other (C# or VB) .NET assemblies.

Though it may not be worth the hassle of doing the .NET side in C#, as you can do basically everything needed .NET in C++/CLI.

(e.g. WinForms UI)

thanks for the info. i code c# stronger but i guess its off to the C++ races!

[Zoffen]

is there going to be any future support to writing to the nci and custom operation with a nethook?
