How to retrieve text from note/labels ?

[MCHulk]

Hi folks,

 

I'm trying to retrieve the text from the notes or labels of the actual loaded MC-Model via a chook. To get the notes/labels is easy, but how to convert the pointer mtid from the structure v8_note to the text.

code:

---

typedef struct              /* structure for notes */

{

byte type; /* 0=witness, 1=leader, 2=label, 3=note */

p_3d ref_pt; /* reference point (text in view) (Z=depth) */

short view; /* view number that note was created in */

real scale; /* internal scale for detail view */

font_attr params; /* font attributes */

ulong mtid; /* memory table index (allocated string) */

v8_wit_ldr ldr; /* leader/witness associated with entity */

eptr_type xptr; /* conversion pointer: note (always null_eptr) */

boolean assoc; /* this entity uses associativity */

p_3d txtpos; /* incremental position used to regenerate note */

short ldr_count; /* number of leaders */

byte pad[2]; /* pad to 8 bytes "none" */

} v8_note;

---

I dont know, how to convert back the memory table record to the desired text.

 

Does someone know how to do this.

 

Thanks in advance,

If you have the Note-Entity, you get the String with the function mTableFindData.

Try:

 

code:

---

ent NoteEnt // This is your note-entity

 

char *szNoteTxt // This should be the Note-Text

 

szNoteTxt=(char *)mTableFindData(NoteEnt.u.n.mtid); // Get the void-data-pointer and type-cast it to char-pointer

Thank you N.Dalhoff, work's fine.

No help with your question (looks like it is solved anyway) but it is great to see some action from our European brothers in mastercam.
