While I retain the connection I always use a new command object. And yes I find the datatable more satisfactory to manipulate, although the overhead would be identical.

The Current Design:
You click on the shortcut and a window pops up asking you for the source directory and target directory. You provide this information and then the files in one directory get copied to another directory. When I schedule this to run as a automated task, the window always pops up asking for the source dir and target dir.

What I would like:
When you schedule the program to run as an automated task, it doesn't ask the user for the source and target directories. If the user needs to change the source and target, they double click on the shortcut and the interface pops up again asking them for the source and target info.

Question:
How do I do this in C#?

Hi,
I think your problem is more about design rather than any particular language. If I read you correctly your current design is interactive and prompts the user for source and target directories.

When running unattended what is your source of directory data? One solution would be to provide a command line interface. e.g.

FileCopier srcdir targetdir

Your code could then do the following:

1) If there are any command line arguments assume that this is an unattended run.
2) Validate the arguments to ensure that the directories exist.
3) Perform your actions on the src and dest directories.
4) Write a log file so that you can check what happened when you weren't there.

Hope that helps, ....Alan.

Welcome to CodeProject Beer | [beer]

I strongly urge you to use beginner based materials to start learning how to program rather than asking questions on internet forums. Things like books or tutorials found on the web. We have a large collection of Articles here at CodeProject some of which are targeting beginners. You can find those articles under the Chapters section of the site menu.

I believe most people will learn beginner level subjects much faster from coordinated material rather than using internet forums.

Check out msdn and look at the FileInfo, DirectoryInfo, StreamReader, and StreamWriter classes. MSDN gives some good examples as to how to use these classes.

As its been already said that you should first read the basic of c#(infact programming).
My suggestion is that even ebfroe posting the question try to Google its out. a simple serach would have yield this [^]result for you.

Getting application version numbers in C#

Matt Fishbeck5-Sep-08 3:53

5-Sep-08 3:53

Hello All.

I would like to know what api calls/functions are required to retrieve all the application version numbers that are currently installed on a windows platform.

What I want is to get all the version numbers as displayed when one goes to the Control Panel->Add/Remove Programs.

I want to get the application names and the versions so I can generate reports, forward in an email etc.

Does any body know how to do this?

Many thanks,
Matt

You need to enumerate the registry entries in this location
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

Try these:

Assembly Version:

Assembly.GetExecutingAssembly().GetName().Version

File Version:

System.Diagnostics.FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location)
