Any windoze .net c# types out there

[timwilky]

OK. to you. I am the anti christ. 10+ years of cutting Java code. You can say what you want about the pros and cons of a language I ai'nt listening . Nuff said on that. I know where there is butter on my bread.

I started off writing APL hieroglyphics in 1977 (Bit like latin, dead language. no need to resurrect). So a code monkey in any language can translate with a bit of time/effort to another.

Well I have a little problem. It turns out that a number of (internal to the parent company) clients have been using a particular package to process salary information and for 12 years have not effectively managed the data they generate.

First issue to their management they want control. Last week I got my hands on a copy of the application. I now know they need to back up a certain directory structure. But because ii is a full time job to run this particular application. they need to easily revert back to a certain date etc.

I therefore had to provide my customer with a tool that will allow them in a (cough spit and wretch) environment to copy workstation (read what you want) windows directory structure to a server which would be robocopied into our corporate all seeing monolith.

So don't laugh. I haven't actively cut any code for some years and never before of windows .net framework.

Those of you Gates brainwash techy wise, please point out my errors. It is supposed to be a simple programme designed to be installed as a desktop icon. To copy a local directory (with a default location) to a network server, where the destination would be date stamped.What have I missed, what have I done wrong? bearing in mind this is my first finger in the windoze cherry

Please give me your comments/feedback etc. Like I say. It is a new audience for me.

Have you tried turning it off and on again? Ctrl Alt Del?

(Sorry)

Just gone up and down simultaneously in my opinon o you Tim - down for putting that evil on the web, up because, well looking at it, it seems fine.

But I dont write that stuff, so not 100%.

Will email to a friend who does tho - just give me the nod that you dont mind that and I will get it over to him.

I would rather ask here where there are a couple of Windows type and get friendly advice, than find a c# forum and get lambasted for not knowing the obvious.

Please ask your friend
