I have to create an application that sorts a list of pdf files from oldest to newest.

I can retrieve the info from one file easily, but how will I retrieve it from all the files in a specific directory, so that I can add their LastWriteTimeUTC property to an arraylist so I can sort them??? 8O

language?

do you have access to some form of Collection? if not you will need to:
1) Acquire the total number of files
2) Remove those without .pdf extension
3) initialise an array to the desired length
4) acquire an index into the array
5) loop through the files, adding each into the newly initialised array..

when you get this far we can discuss sorting algorithms.. bubble sort anything below 50 only... thereafter your trade-off in using a quick or quick+insertion sort combination is the better option...

language?

C#.Net in Visual Studio 2003

then you already have access to dynamic, typed, collections, as well as all the static sort methods that go with them...

what have you done so far?

I don't know how this is gonna look...
It gives me an error : The given path's format is not supported


string filePath = "C:/pdf/";
ArrayList fileLst = new ArrayList();

Directory fDir;
string [] fFile = Directory.GetFiles(filePath);
int x = 0;
foreach (string DirFile in fFile)
{
FileInfo infoF = new FileInfo(filePath + DirFile.ToString() + ".pdf");
fileLst.Add(infoF.LastWriteTimeUtc);
fileLstBox.Items.Add(x.ToString()+ ". " + fileLst[x]);
x++;
}

MessageBox.Show("Time :" + fileLst[0] + " Time 2 : " + fileLst[1]);

Hi, try this

private void Form1_Load(object sender, System.EventArgs e)
{
DirectoryInfo theDir = new DirectoryInfo("c:\\pdf");
FileInfo[] theFiles = theDir.GetFiles();

int intCount = 0;
if (theFiles.Length > 0)
{
// Do sorting
if (theFiles.Length > 1)
{
FileInfo tmpFile;
int intPass = (theFiles.Length - 1);
bool blnDone = true;

while (intPass >= 0 & blnDone == false)
{
blnDone = true;
for(intCount = 0; intCount <= (intPass - 1); intCount++)
{
if (theFiles[intCount].LastWriteTimeUtc > theFiles[intCount + 1].LastWriteTimeUtc)
{
blnDone = false;
tmpFile = theFiles[intCount + 1];
theFiles[intCount + 1] = theFiles[intCount];
theFiles[intCount] = tmpFile;
}
}
intPass -= 1;
}
}

//Show files
for(intCount = 0; intCount <= (theFiles.Length - 1); intCount++)
{
fileLstBox.Items.Add(intCount.ToString() + " - " + theFiles[intCount].FullName + " : " + theFiles[intCount].LastWriteTimeUtc);
}
}
}

Edit: crap! stupid indenting

never mind the indenting...you helped me a lot

the FileInfo[] part was what I needed

Tx

I have to forms for this application --- mainForm and configForm

I do not want the configForm to appear in the windows taksbar when I activate it from within the mainForm.

I also want the app to minimize to the system tray when I click minimize

Any help....I'm busy googling

You'll need a NotifyIcon, and a Context menu. Declared in code, in your case.

Right, this app is close to finished...

I want to write the contents of a richTextBox to a text file, in exactly the same context as I view it in my app. In other words, where there is a line break, I want it to to be shown in the text file as well

I use this,
StreamWriter wLog = new StreamWriter({file details});
wLog.WriteLine(detailsTxtBox.Text);
wLog.Flush();
wLog.Close();

however, this writes all the lines in my textbox side by side, with a '□' showing where the line breaks should be...any ideas...

what are you opeming the file with?

Well, seeing that it's a textfile, with a *.log extension, i'd like to open it with notepad...

Shoul I rather just use a multiline Textbox instead of a richTextBox???

notepad does not support some rich text. try opening it in wordpad and see what happens??
