Good People,

I have attempted to use File.Copy to copy from a source file to a new file. However, even after I get the apps running directory (usine AppDomain.CurrentDomain.BaseDirectory + @"UserImages\") it still does not work. It throws an exception claiming it can't find part of the directory of the destination file. What I don't understand is that using AppDomain.CurrentDomain.BaseDirectory + @"Database\AppDatabase.vdb3" to find my database for the application works as expected.

Do I have to create the new file first before writing to it? Doesn't File.Copy create the new file? Any ideas?

Thanks,
Blitz

Hi,

Windows does not create the directory if it does not already exist.
Windows Explorer will create directories for you, the programming interfaces don't.
So you have to take care of that yourself using Directory.CreateDirectory.

BTW: there is no need to test, creating a directory that already exists is harmless.

Thanks for your reply.

The directory exists, but the file doesn't. Do I need to create the file? The examples in msdn didn't indicate I need to create the file. Plus, how would I create an empty jpg file?

Thanks again.

You'd better make sure the destination directory exist while coping file.Hope such code can help:

string strPath = AppDomain.CurrentDomain.BaseDirectory + @"UserImages\";
// check the directory existence
if(!Directory.Exists(strPath))
	Directory.CreateDirectory(strPath);
//...your file copy code here...
// eg. 
//   File.Copy("d:\\a.txt", strPath + "b.txt");

Instead of concatenating the path variable together, use System.IO.Path.Combine. That will automatically handle the backslashes. For your problem: as the other replies have stated, the path to the destination folder doesn't exist. You need to create it

Thank you for all of your replies.

What I don't understand, however, is that the folder does exist. In fact, the path it shows as not being able to find is, in fact, the correct path to the folder. I need it to place the new file in the folder - which already exists. So the directory already exists.

I apologize for my confusion, but what am I missing?

Thanks,
Blitz

OMG!!! You all are so right! Thanks. Indeed, it did not exist. See, my error was that I added the "UserImages" folder to my project. However, it was not in my output directory. I failed to realize the difference. Now I know, and knowing is half the battle Smile | :)

Thanks so much for your help.

I think you'd better create a control(label, textbox,etc..)first associated with that item you clicked, then add to it to your TableLayoutPanel's controls.
Hope can help you.

Create an event for the change in DateTimePicker 1. In that event, increment DateTimePicker 2.

How to extract a list of substrings from a string which match specified format using Regex

For exemple, i have a string = "%alan#23%12:34:50#ab %regular#]r";

Extract string which enclosed by '%' and '#'

The substring result should be

substr[0] = "alan";<br />
substr[1] = "12:34:50";<br />
substr[2] = "regular";

How to do it in Regex?

Read up on grouping in regex. You can do exactly this by specifying which parts of your match to return.

i tried this code..

string str = "%alan#23%12:34:50#ab %regular#]r";

Regex RE = new Regex(@"(\%+)\#");
MatchCollection MC = RE.Matches(str);

if (MC.Count == 0) MessageBox.Show("No match");
foreach (Match M in MC)
{
    MessageBox.Show(M.ToString());
}

But when execute it, i only got "No match" message box. Frown | :(

Why Not.....

I solved it as i add COM reference Microsoft word 12.0 Object Library.

Then i code this..

try
{
string Msfilename = System.Windows.Forms.Application.StartupPath;
Msfilename = Msfilename + "\\File\\Test.doc";
System.Diagnostics.Process.Start(Msfilename);
}
catch (Win32Exception ex)
{
MessageBox.Show(ex.Message);
}

I got the solution.

Reading a file under vista

I have a file that I want to read, it's an RTF. I do this:

System.IO.FileStream fStream = new System.IO.FileStream(fileName, System.IO.FileMode.Open);

( I need a stream to pass to the WPF Rich Text control ). This fails with a permissions error, no matter where in the file system the file is. Any suggestions on how to make Vista work ?

This is real pain. Is it possible to put the file under users folder (users\user name\application data)? I am able to reproduce your issue on my Vista Business and it got solved when I moved the file to the above said directory. Environment.GetFolderPath can be used to get the path.

I have heard about creating manifest files. I haven't tried it yet. Here[^] is the MSDN article for that.

We have 750 MB of data, I don't want that to be stored per user.

What I found was that File.ReadAllBytes works fine for the same files, and then I can put the bytes into a memory stream. Which, I'm sure you'll agree, is not buggy at all.....

Hi Christian,

from the statement System.IO.FileStream fStream = new System.IO.FileStream(fileName, System.IO.FileMode.Open); Windows does not know whether you will want to read and/or write, hence you may get a File Access Denied situation depending on exact file location.

Try adding System.IO.FileAccess.Read as an extra parameter.

Perhaps you need to reword your question so that it might perhaps indicate something that is physically possible. What do you want to achieve ?
