draw_txt_on_screen()

[wire123]

draw_txt_on_screen(p_3d pt, char txt[], byte color);

Anybody have any experience with the above function, pg. 9-3 of the chook manual.

When I run it, my system throws a nasty error from unknown module and wants to shut down Mastercam.

 

Thanks.

What is the error and how exactly are you using draw_txt_on_screen()? Maybe post a snippet of your code.

[wire123]

Sorry about that, here you are.

 

static void WR190( variables)

{

p_3d TxtLoc; //for draw_txt_on_screen() way below

char textOut[20] = {{'0'}};

strcpy ( textOut, "Flat: .562");

 

//many lines of working code

 

if( pt55[X]>0 )

{ TxtLoc[X] = pt55[X];

TxtLoc[Y] = pt55[Y] + 1.0;

TxtLoc[Z] = 0;

draw_txt_on_screen (TxtLoc, textOut, RED); //blows up

}

} //MyFunc() end

 

This program has performed and illegal operation and will be shut down.

I see you're in V8.

What are the date/time of the M_INIT.OBJ and M_PTRS.OBJ you're using? I think we found a problem in the V8 cycle with this function.

I'm not sure why it's crashing for you. Perhaps try using sprintf() to add data to your string instead of strcpy(). I try to avoid character arrays whenever possible (the STL rocks!) and I can't recall if strcat() appends the terminator to the end of the string or not. sprintf() does, though.

 

But I've found that draw_txt_on_screen() doesn't write to the DB. So if it creates text on the screen, the moment the graphics window updates itself, your newly created text vanishes. If you want it to stay on the screen, look into creating a note or a witness.

Sorry for the delay, I was pulled to other projects.

Here are my date time stamps.

With the char array I also tried:

char txtout[]="some text to print";

 

m_init.obj 01/25/01 3:16pm

m_ptrs.obj 01/25/01 3:16pm

 

I really don't need the text to say around past the initial screen.

Wire123,

We did indeed correct something in the C-Hook development kit related to draw_txt_on_screen() AFTER January 2001. Do you have a V8.1.1 CD? The correction is in the C-Hook kit on that CD (which is dated @ April 2001). Even better - do you have access to V9? If so, the fix is there too (and you'll get more help).

If you don't have anything beyond V8.1, e-mail me at [email protected] and I'll see what I can do for you

I have a v9 CD. I recompiled with those .OBJ files. It no longer blows up. And it prints!

 

Thanks all.
