X NC Path (C-Hook Question)

[Bullines]

How would I be able to programatically determine the path of the NC directory? In previous versions, that was handled by the nc_prefix variable. That doesn't appear to be available in X.

 

The closest thing I've seen is the szNcPath in the file_ctrl structure? But obviously I can't create a new file_ctrl variable since its szNCPath will be empty (or some random memory address). Perhaps something else has a pointer to an existing file_ctrl structure?

 

Do I need to create a new CCNCControl object to use GetNcPath()?

 

If worse comes to worse, I can assemble the path myself based on the install directory and whether the user is running Mill/Lathe/Router but I haven't found a way in that big CHM to determine even that, yet.

Chris,

 

There may be other ways (even simpler ways), but this works for me ->

 

Here is a seriously snipped code sample.

 

GetData() loops thru all the operations in the Toolpath Manager and calls GrpData() to gather up data on each Machine Group.

---------------------------------------------

 

 

// Gather data about the operation

bool GrpData(op_list *opl)

{

 

if (opl == NULL) { return false; }

 

char ncSuffix[_MAX_EXT] = "";

char ncPrefix[_MAX_PATH] = "";

 

group_list *gpl = OMgetOpMachineGroup(opl->op.op_idn, FALSE);

if (gpl == NULL) { return false; }

 

// if (gpl->name) has changed from last time, we're into a NEW Machine Group

 

CCNCMachine *pMachine = new CCNCMachine(gpl, FALSE, FALSE);

if (pMachine == NULL) { return false; } // Oops!

 

strcpy (ncPrefix, pMachine->NCPrefix()); // save for later

strcpy (ncSuffix, pMachine->NCSuffix()); // save for later

 

// -- snip --

 

return true;

}

 

 

// Loop thru all the operations

bool GetData()

{

 

op_list *opl = op_list_ptr;

 

while (opl != NULL)

{

bOK = GrpData(opl);

if (!bOK) { break; }

opl = opl->next_ptr;

}

 

return bOK;

}
