Abnormal Program Termination when executed from C:/Program Files

[m37h0d]

why might an application copied into a subfolder of Program Files terminate abnormally, when it executes fine from other locations? i got nothing.

[tabstop]

Is it looking for a file with a relative path?

Perhaps it handles spaces in pathnames badly.
Perhaps it ... nevermind, post actual code which shows the problem and lets cut to the chase instead of playing 20 questions.

yes! is that a nono?

i can't post all 200+ files of text that make up my app!

i can't tell the hell the problem is.

If you're using relative paths, and you move one thing, don't you think you would need to move the other so that the relative paths remain the same?

Whether relative paths+moving files or full paths+keeping the file in the same place always is the right choice we don't know, but you'll have to pick one.

Well you could begin by adding more rigorous error checking to everywhere you open a file for example.

Or is that any error checking?

i keep everything in the application directory so the relative path is always "/"

ok, actually i take that back. i now have an idea of where the problem is. it happens when i successfully connect to a USB device.

it doesn't happen if the device isn't plugged in. will post code shortly.

i am aware that i will be lambasted for this; it was written somewhat hastily and i haven't had time to rework it.

the derived object i'm using is S255_256

[tabstop]

i keep everything in the application directory so the relative path is always "/"

"/" sure as heck isn't the current working directory. However, I glanced through the code long enough to see that (at least once) you tacked "/stuff" on to the end of the cwd, and that is probably ok.

Anyway, are these two posts supposed to be different, and what is all this stuff, and I thought you had narrowed down the error but I didn't see, on a skim, you pointing anything out.

It's called the art of debugging. Use a debugger. Find out how to reproduce the problem, step through it in the debugger. Visual Studio has one very powerful and easy, visual debugger.

I prefer this - http://www.microsoft.com/whdc/devtoo...g/default.mspx
You can run and debug the program wherever it is, and not just inside your project.

Plus, there's lots of "power user" features in windbg.

i narrowed it down to something in these 4 files out of the 200 in my project...:\

i don't know where.

when i have the spectrometer unplugged, it doesn't crash. when it's plugged in and executed from the ...\Program Files\... directory, it does.
