AutoCAD Visual LISP / AutoLISP :: Expire Date For A Function
Nov 27, 2012
I want to define en expiration date in registry, after that date the some LISP programs does not allow to run. I think that suitable commands are SetEnv and GetEnv.
define a ExpDt variable that contains Expiry Date as a string. And add some statements inside of the LISP program to call this variable and check it with today's date.
I should define once time in autocad:
(setenv "expdt" "130101"); YYMMDD date for validation period (2013.01.01)
and check this every time that a lisp program should be execeute:
(getenv "expdt") ; if today's date(with YYMMDD format) ">" expdt then lisp program doen not allow to run and should be halted.
for e.g. on 2013.02.28: "130228" > "130101" ==> so the lisp function should be halted and will not work!
(without any alert or message)
a sample list function: (how can implement on this lisp function?)
(defun c:3()
(setq w t)
(while w
(setq a (getpoint "
pick point:"))
(setq p1 (list (- (car a) 0.5)(- (cadr a) 0.5)))
(setq p2 (list (+(car a) 0.5)(+(cadr a) 0.5)))
(command "erase" "w" p1 p2 "")
(command "INSERT" "*3" a "" "" "0")
)
(if (= a nil)(setq w nil))
)
I'm trying to build a command to replace AutoCAD's "DI" command, to give distance and delta x, y, and z values in decimal and imperial, and keep the angles in XY plane and out of XY plane.
I have a attributed titleblock. Sometime in the future I will need to change the date attribute to another value, i.e.. 7-11 to 9-11.
I can't place a text string in the title block because this title block is used for multiple drawings and the date will be different for different sets. I can't have numerous title blocks because of the client's requirements.
Question:
Is there a way to write a script to open a drawing, look for the specific attribute, change the date value, save and close the drawing - across multiple sheets? Would a lisp routine called by the script be able to do this? Or a script file called by the original script file? CAn you even use a script file in this manner?
I posted a version of the Offset command that lets you Undo individual Offsets and change the offset distance/Through option, without getting out of the command, at Cadalyst CAD Tips: URL....
It's an upgraded version of an earlier concept by Gopal Ramesh. It's been downloaded almost three times every day since it went up, so I guess people expect it will be useful.
But the website's description includes: "this routine does not provide access to the Layer or Erase options of the built-in Offset command." The reason for that is that I'm working back in 2004, so those options are not present for me to emulate. [The Undo option in the routine is one that was added in some later version, but is a very useful enhancement for people using older versions, like me.]
I do also have an Offset-to-any-Layer [not just the source's or the current Layer] routine posted there: URL....
And I have a simple little routine to Offset something and Erase the source object. So I think I have all the "pieces" to include those options that newer versions have, but that I don't. I would like to combine the functionalities into the Offset-with-running-options routine. That way, if people want to use it to redefine the Offset command as I have done, in order to get the while-running distance change option, those working in newer versions won't be losing the Erase and Layer options in the process, and those in older versions will be gaining yet more options.
In the foreach function can you use math like (foreach pt1 (add 1) so that foreach one you pick it adds one the next one will be named pt2 then pt3 and so on.
how to append I’m assuming its not write-line but append line. And also I’m having trouble recording the date variable… I keep getting error bad argument type stringp nil
; Appends usage count by DATE long variable...(setq g(open "C:/ICT/AutoCAD_Architecture_suite_2012/CUSTOM/WOOD Clones/PEN/USSAGELOG.PEN" "w"))(setq MYDATE DATE)(write-line MYDATE g); AS ABSOLUTE LAST WE NEED TO CLOSE THE TEXTFILE...(close g)
I have the following code snippet I’m trying to append the file named USAGELOG.TXT to record the date of executions
The error below has appeared randomly when AutoCAD 2011 is started. There was not an error of this sort, but it suddenly appeared and some of the LISP routines will no longer work.

a compiled function definition. You may want to define it using defun-q:
I prepared a code to calculate number of days between two date.
I want to know how can I define negligible arguments for my lisp routins. It means if I omitted the arguments, lisp code can handle it without any errors ("; error: too few arguments")
In this case, my program defined as: (TotalDays 1st_date 2nd_date)
(TotalDays 1978 03 21 2013 06 25)
and I want to have flexibility: if I use this routine as (TotalDays 1978 03 21), the program should substitute today's date with second date.
I know if I put "nil" instead of date for 2nd_date, It will not be an error, because:
but that's not my favourite!, how can I omitted 2nd_date completely? as (TotalDays 1978 03 21)
Here is my lisp

There is no other mention of STRNUM in the whole of the lisp.
There is an accompanying setvars.dat, wherein apparently, the writer compiled a data file of all the system variables in AutoCAD2008, each variable being followed by an '=' and then a description of the variable.
If necessary I can post the whole lisp and dat file, but was hoping to discover the intention from the above extract and therfore where I might work out an alternative to this line.
Looking to turn a string to a real? If so, why are there two 'arguments' following the 'function' STRNUM?
I was able to find/update a LISP program that returns the dynamic block to its original state, overriding the anonymous name and make the actual block name the effective name. I am in the process of manipulating the LISP program so I can select multiple blocks rather than one at a time.
I have a simple lisp function to add a scale axis to a drawing by calling a script, renamed the drawing by appending "withScale" to the file name, and then closing the file. I placed a call to the function in the acad.lsp file in the startup suite. The idea was to batch process all files by simply opening them. Upon open the startup acad.lsp file runs, which calls my lisp function, which in turn calls the scale script. It should then execute the renaming, saving, and closing commands. The problem is that it is calling the script fine and renaming the file, but it does not save the changes before closing. Here is the lisp function
I have a list function that asks for the user to pick points when it is run. It looks something like this (foo arg1 arg2) When invoked it asks the user to pick points and press enter when done It.
Instead of getting the points from the user i want to pass it a list of pre-defined points. The code cannot be changed so I must use it as is.Is this possible, if so how can it be done?
I've got a subroutine that gets the centroid of a closed polygon (lwpoly). It appears to fail if the polygon has any zero length line segments. I've added a trap that catches the error and "highlights" the offending polygon, but it stops there and does not return to the main function that called the subroutine. Is there a way to get back to the main function from the trap?
Here's the subroutine (original function by _gile (Autodesk LISP Forum 9-18-2006):
(defun return-centroid (lwpoly space / obj Region Centroid) (setq *error* trap1) (setq obj (vlax-ename->vla-object lwpoly)) (setq Region (vlax-invoke space 'addRegion (list obj))) (setq Centroid (trans (vlax-get (car Region) 'Centroid) 1 0)) (vla-delete (car Region))
I am looking for a function to print out the entire entity list of the selected entity...
so... walking down through the entity data... print out what it finds... any time it encounters an entity name... then do an entget and print that out too.
I am aware of the plot stamp available in the Plot Dialog box, however, we are looking at ways to imbed this info in the dwg. I currently have the WD_TB with an attribute for FULLFILENAME, an attribute for PLOT DATE, and an attribute for PLOT TIME12. So I get the information on the dwg. I would like to be able to run all these attributes as a string. I have tried FULLFILENAME|PLOT DATE|PLOT TIME12 with spaces, commas, ( ), " ", etc. and I do not know the proper syntax to get this to work. I have also tried (getenv "FULLFILENAME") or the getvar, in the title descriptions box.
I have included both a text and a date as part of the photo caption on each of my photos. When I have attempted to search for a specific date or year, however, nothing comes up. For example, if I search for my photo on "Fido 1985", I can find Fido, but if I simply enter "1985", I get nothing.
Is there a lisp that will allow me to do a continuous dimension, but will alternate the dimension position from low, high, low and high? If there is no lisp already created, how to create one?
See Continuous dimension attachment for example.
I work at a glass and glazing company and this is how we dimension mullion width and DLO. See typical window dimensioning attachment for window elevation with dimensions.
I have a list ("temp.dwg" "temp2.dwg") and would like to add the string "insert text here" into each item in the list resulting in ("insert text heretemp.dwg" "insert textheretemp2.dwg"). how would i go about doing that using LISP?
Is there a way to programatically set a visual style before a drawing actually opens?
We have some huge models and people seem to forget to change their visual styles back to 2D wireframe before saving and exiting drawings. Some models will crash on some workstations when trying to open in a rendered mode.
I found a lisp with a function that looked to set viewport visual styles. But it does not seem to be supported anymore. --> (vla-put-VisualStyle vport 1)
I'm trying to write a lisp routine that, when I invoke the mleader command, osmode is set to "nearest" & orthomode is set off. I then would like the original settings to be returned.
Lisp that switches back on Selection Preview i.e. thickens and highlights lines when you hover over them?I don't know why, but they are always unticking the boxes.
Is it possible to execute a certain command based on multiple selections withinin a dcl? for example: two radio colums, one with selections A and B, and a second with selections 1 and 2. is it possible to program commands based on user selections from each column? ex: if A and 1- do a command. A 2- do a different command, etc...
I tried :
(action_tile "key1" "(setq A t") (action_tile "key2" "(setq B t")
I am trying to find a lisp that would get an attribute value (tag name = NBR_5) . I'm trying to run a simple routine that would let the user place the value from the titleblock attribute as text on a drawing. I see a ton of articles regarding getting attributes but I am not well versed in programming.
