File comes in over EDI as .today. I need to change it to .txt and move it to another folder. Everything works just fine for about 3-5 files, then starts throwing exceptions. I tried handling those, but that doesn't solve the problem. I'm also getting sporadic (filename cannot be null) exceptions as well. I just can't seem to figure this out.

Perhaps the files are still in use. The FileSystemWatcher event is raised when a file is created, but the creating process can still be writing to it. See here for a possible solution.

I am currently working on a windows forms app using c# that will be able to convert Pastel Partner trial balances to Pastel Evolution compatible balances.
I am trying to implement code that will skip all lines in the sheet that do not have account codes (col 2)
Please assist with a code example on how to do this, it would be highly appreciated!

To this (Evolution)...
This is my form and code so far...

If the account codes are in col 2, then you can check for empty values in the loop which you already have
string[] fields = lines[i].Split(',');
if (fields[1] != "") <-- check if account code is an empty string
{
if (recordMatches(searchTerm , fields , positionOfSearch))

I am a C # amateur I am not a professional developer and would like to ask my colleagues for help, I would like to make a C # program that connects to an SSH server. Then, depending on the selected value in combobox, the program downloads the appropriate string and I would like to send it to the ssh server to the specified path path and save the value from the string to the file;)
I tried to rewrite the code but something did not work out and I stopped in my place ;( Can anyone help me. Thanks in advance for your help.

I'm trying to make a windows form application to do the same thing that I have a console application doing. The design is just a box with two labels (going to try to add a progress bar later on) but for some reason the code is not working correctly.

}
}
private static void CopyAllFiles(string Source, string Destination)
{
try
{
// Get the subdirectories for the specified directory.
DirectoryInfo dir = new DirectoryInfo(Source);
DirectoryInfo[] dirs = dir.GetDirectories();
if (!dir.Exists)
{
Label infoBoxErr = new Label();
infoBoxErr.Text = "Directory could not be found.";
}
// If the destination directory doesn't exist, create it.
if (!Directory.Exists(Destination))
{
Directory.CreateDirectory(Destination);
}
// Get the files in the directory and copy them to the new location.
FileInfo[] files = dir.GetFiles();
foreach (FileInfo file in files)

file.CopyTo(temppath, true);
}

}
}
private void progressBar1_Click(object sender, EventArgs e)
{
}
}
}
The problem is that it outputs the text in the labels as expected as if it was successful. Yet it does not create a new folder or copy any of the files. I have no idea why and it's not giving me any errors!
First of all you catch exception within CopyAllFiles method. And its code
catch (Exception ex)
{
Label infoBoxErr = new Label();
infoBoxErr.Text = "Oh. Something didn't work, sorry. Might have been this: " + ex.Message + " lol!";
}
doesn't do anything because it creates label infoBoxErr in memory and doesn't display it at all.
So, the following code
try
{
CopyAllFiles(Source, Destination);
infoBox.Text = "Files backed up successfully.";
if (System.IO.Directory.Exists(#"D:\" + date + #"System Volume Information"))
{
Directory.Delete(#"D:\" + date + #"System Volume Information", true);
infoBox.Text = "Files backed up successfully.\n System Volume Information folder deleted.\n Backup successfull.";
}
else
{
infoBox.Text = "System Volume Information folder does not exist and therefore was not deleted.\n Backup successfull.";
}
}
catch (Exception ez)
{
infoBox.Text = "Umm, something didn't work. Oh maybe it was this? " + ez.Message;
}
never reaches the catch block (because of inner catch in CopyAllFiles method) and just displays success text.
So I'd suggest you to remove that inner catch and see what happens.
i am currently working on a Windows Forms App in c# which will allow the user to add or delete records. when i hit the button to display all the records written to the file the files appear, but when i try to delete by transact number i get an exception saying that "The process cannot access the the because it is being used somewhere else". i have tried putting it in a try-catch block to make sure the reader/writer will close and still not working code will be attached any help is greatly appreciated. p.s im not looking for code to finish this project just help getting by this exception and make it work like it is suppose.

Firstly, I would just like to add that I am an absolute beginner at C#, I'm doing my best to learn so I am sorry if this is a noob question, but I have hit a brick wall.
I am working on a program that when finished it will find .DBF files from a specified folder, read the file and insert into a mysql database. I am stuck pretty much at the first hurdle.
I am trying to make the program loop through each file it finds and read them.
I can't seem to be able to access the filename string from the GetFiles() Void.
Is there another way around passing the filename to the queryString rather than specifying it myself?
here is my code -
