Homework 2 is up (and WebCT news) January 24, 2007

Posted by Ron in 3790 Administrivia.

Homework 2 is now up on the homework page. Because of the complexity of the assignment, the due date is now February 7. Again, please try out the PERMAP software early to make sure it works on your system — if you have trouble installing it you don’t want to find out at the last minute.

Also, your current grades should be available on WebCT.



1. Jamie Meyers - January 25, 2007

For permap to work, print spooler (via services.msc) must be on, for those of us who don’t have a printer.

2. Ron - January 25, 2007

I have not run into this problem. Could you be more specific?

3. Ron - January 25, 2007

I talked with Jamie, and here’s the problem: if you’ve turned off the print spooler on your Windows box to save memory, PERMAP will give you the error: “Run-time error 482. Printer Error.”

If this happens, simply turn the print spooler back on to run PERMAP.

For many people this will not be an issue because the print spooler is on by default in Windows.

I’m getting the following error: “Run-time error “380′: Invalid property value”…. Please, help?

Thanks in advance,


5. Ron - January 28, 2007

Can you tell me a bit more about your installation. Did you install using the standard installation routine, and do you have administrator rights on your machine?

6. Patrick Bonaparte - January 28, 2007

Ok, so I tried the Print Spooler fix to no avail. I stopped and started the service under management controls but I still get the same Printer Error.

I installed it on a Mac, w/ boot camp, but that shouldn’t really be the problem. I used both the standard installation routine and I tried unzipping the .cab file. I will have to try on a friends computer soon.

7. Ron - January 28, 2007

Very good. Please let us know how it goes. Good luck.

8. John Kelly - January 30, 2007

I am also getting the runtime error 380 invalid property value, I have installed it on my windows machine following the intructions, and I have tried to install it several times. How would I fix this?

9. Ron - January 30, 2007

We’re still working on it. In the meantime, you might try it out on a lab machine. Can you list your current OS (e.g., “Windows XP”, etc), and the exact error message? Thanks.

10. Jimmy M. Espana - January 30, 2007

The error = “Run-time error “380′: Invalid property value”

O.S. = Windows XP (Professionl) Service Pack 2 [ Version 2002 ]

Hardware = Dell 700m Laptop

P.S. I am the administrator (and I am logged-in as the administrator)

11. Patrick Bonaparte - January 31, 2007

Well…I have been trying on lab computers but instead of getting the Printer Error, I’m getting the Invalid property value that everyone else has been getting.

“Run-time error “380′: Invalid property value”

They are the standard, Windows XP installs with administrator priveleges. Do I have to keep trying different computers until I finally find one that it will run on?

12. Ron - January 31, 2007

I’ve sent a note to Ron Heady, the professor who wrote the code, to see if we can get some help. More soon.

13. Stephen Tyler - January 31, 2007

I am also getting the error:
“Run-time error “380′: Invalid property value”

I am running windows xp pro service pack 2.

14. Justin - February 3, 2007

Here’s a summary of what the author, Ron Heady, said:

Error 380 is an error that they have known about for years. It usually occurs on laptops (most often on Sony Vaio) but also occurs occasionally on older desktops. This is an “invalid Property Value” error which means the operating system is requesting a resource that isn’t available. They (he with input from other users) have tried to solve this problem for some time, but can’t determine the root. If any of you guys can figure it out, the author would be quite grateful.

Error 482 is a newly encountered problem. Since the error is occuring at startup, it may be that Permap’s default settings are calling for a printer that is not connected to your system. A spooler could do that. If you would, please check the following… Click File and let us know if “Redirect HiRes Printer …” is checked, and then select “Change Printer Settings” and see if there is any funny business there. That is, does it show a printer that is not connected to your computer, or does the default printer have some strage property setting. If Permap is trying to set up a nonexistent printer, the author thinks he might be able to fix it.

15. Justin - February 3, 2007

A couple more items…

Has anyone gotten Permap to work on a lab machine? If so, please let us know (by email: jang/amator/rwf at cc) which lab, which machine(s), and any other relevant information on getting it to work.

If you’re having problems running Permap, using the Event Viewer in Windows may be able to provide more debugging information. To open Event Viewer, click Start, click Control Panel, click Performance and Maintenance, click Administrative Tools, and then double-click Event Viewer.

16. Phillip - February 3, 2007

I’ve started print services using the computer management utility and I still get 482 errors. Do I need to also have a printer installed in order for it to work?

OS: XP Pro SP2

17. Courtland - February 6, 2007

Just to help some people out with printing from Permap, you can click the option print output to file (which is located under the normal print stuff). Then afterwards you select the High Quality Print option (ctrl+q, i think) and this will make an image in the permap folder which you can print as you would a normal image.
