using acedCommand to redefine a block insert

Anonymous — Thu, 14 Jul 2005 17:08:14 GMT

In my code, Im checking to see if a particular block exists before atteming to insert a new one.
If if does exist, I want to redefine it, but when I put a "yes" in the command string at the point
where the insert command would ask for it, it doesnt seem to work. I still get the old block inserted.
Can someone tell me what I have done wrong here, or if this is even possible this way?
Thanks
Perry

code snippet---------------------------------------------------------------------------------------
if (blockExists)
acedCommand(RTSTR, "INSERT",
RTSTR, windInfo.sTitleBlockToInsert, //blockname,
RTSTR, "YES", //answer redefinition prompt
RTSTR, "0,0", //insertion point,
RTSHORT, 1, //xscale,
RTSHORT, 1, //yscale,
RTSHORT, 0, //rotation angle
RTNONE);
else
acedCommand(RTSTR, "INSERT",
RTSTR, windInfo.sTitleBlockToInsert, //blockname,
RTSTR, "0,0", //insertion point,
RTSHORT, 1, //xscale,
RTSHORT, 1, //yscale,
RTSHORT, 0, //rotation angle
RTNONE);

You show code that calls acedCommand, and
passes variables as params, but you do not
show what the actual value(s) of the variable(s)
are, which means that it is difficult to help you,
since we don't know what you're actually passing
to acedCommand().

I will take a guess, that your variable contains
the name of the block, which isn't going to tell
AutoCAD to redefine it.

To redefine an existing block, you need to use
blockname=filename (or blockname= if the block
and filename are the same, and the file is in the
search path).

Yes Tony Im passing in a variable for the block name. In this case it evaluates to:
"C:\Documents and Settings\perry\My Documents\My code\C++\Acad\tblocker 2002\Debug\title blocks\title-b2.dwg"
So I thought this would redefine the block existing in the drawing by the name of "title-b2".
Apparently, Im wrong about this.

No comment about what?

I already mentioned that to redefine a block from a DWG
file, you must use "blockname=filename" with INSERT, not
just the filename.

So, your parameter for the blockname with INSERT would
be something like

"TITLE-B2=C:\...\title blocks\title-b2.dwg".

Ok, I was not aware of the need for the "dwg=..." part in front of the path name.
