What kind of program, and what registry entries are you using?

hi harry,
i have had a similar problem with one of my programs called >Canary...it monitors computer use and internet access by keeping track of the title bars of open windows...my program runs great under win95/98/me...BUT it has a number of problems under xp...it runs but records nothing and some users have mentioned that their system became highly unstable after installing my program and were very eager to get rid of it
i never found out why my program did this...it was written in vds 4.5
sorry i don't have an answer but just letting you know that i came across the same thing
serge

If a program is not run as an adminstrative user then it will not be able to access certain folders nor write to parts of the registry. You really need to keep to HKCU registry keys, and for disk space create folders under <user>\Application Data.
Having said that, I have a problem with my program GetBack (written in VDS 5) that has me completely stumped. The user claims to be runing as an administrative user and has sent screenshots to show exactly what he is doing. But it shouldn't matter as GetBack runs perfectly as an ordinary user as well. The problems he is having indicate that my program is being prevented from creating *any* file, either the folder it needs to work in, or a shortcut in the user programs Startup group that ensures it is started automatically whenever he logs in. If anyone has any ideas what could cause this I'd like to hear them.

All I can think of Jules is to have him check his secruity policies. Also is the user on a Domain? If so then he may be logging into the domain as a different user than his local user account and the domain user may not have access to the local computer. Have the user login to the local machine and not a domain then try your program again and see what happens.

2 things
the program uses lots of math
1. I write number of uses (its a demo version)
in the registry under root.
2. i make a ini file on the fly as it has some info i don't want to share with just anybody as it is key to how the program calcs
the factors .its deleted at the end of each use.
thanks,
harry |

Like everyone is mentioning above, it might be permissions issue on the
XP machines.
If the user does not have permission to write to the registry, then your
program won't be able to write to the registry.

With math you've got to bear in mind that not all people use period as the decimal separator. If you've got any constants they may not be interpreted correctly. It's not an XP thing but a locale thing. You have to use OPTION DECIMALSEP. I've forgotten this so many times, it's why the VDS 5 compiler a displays warning if you've done any math and not used it.

And which compiler might that be???
I've forgotten the DECIMALSEP issue lotsa times but I'm yet to see any warning about that.

OPTION DECIMALSEP is set to "."
so i guess that it is the permission
i'll see if the user can change it. it is a single user and a at home box.
Can someone tell me what settings need to be changed ?
i only have win 95/98 and i'm in the dark about xp.
thanks
