Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

Hello safeena

Please post programming questions only. Nobody has time to research for you and even if some body do it for you, you wouldn't learn anything being a student.

I hope you understand. BTW the topic of your project is so depressing.

Re: How to check if extensions follows up in a list?

11-Mar-09 23:31

I've been brainstorming with this for a long time... and havent figured it out yet.

I'm just asking for a tip to point me in the right direction... because im going in circles.

The problem i have is this:

Example folder contains files .jpg and .tif. I want to check them if they follow up correctly.

So... this is an example of an OK folder:
Example Folder>
-1.jpg
-2.tif
-3.jpg
-4.tif
-5.jpg
-6.jpg
-7.tif
-8.tif
-9.jpg
-10.tif

You can see, that the files go - 1-1 or 2-2 (maybe also 3-3) in extension.

this is when an error would occcur:
Example Folder>
-1.jpg
-2.tif
-3.jpg
-4.jpg
-5.tif
-6.jpg
-7.tif
-8.jpg

the extensions dont follow up. the order of the next extension is not the same.

Any idea? Please?

Regards,
Matjaž

So you want your program to switch between jpg and tif for every other file while incrementing the file name?

Re: How to check if extensions follows up in a list?

11-Mar-09 23:40

ummm not incrementing.

let me rewrite... (ps: sorry for my bad english)

i select a folder. get files from that folder to and arraylist.
go with "for" loop through items in that arralist and check extensions (Path.GetExtension). Well... i would go like that.

The filenames are incremental... (8 digits type - 00000001 etc) but i really dont have an idea how to put everything in the code. Was trying with this but...

One of the ideas was to get extension. if its "tif" then increment int TIFS and if its an JPG, stop counting tifs and add +1 to jpg - then check if the Integer TIFS and JPGS match.. bah... i'm so lost.

Matjaž

I understand what your asking now, sorry for the confusion. I think you can solve this problem by counting the number of like files. Final Question are the files always going to be in chronological order?

Re: How to check if extensions follows up in a list?

Do you mean this?

If file 1 and 2 are jpg, then 3 and 4 must be tif. That is: 2-2

if 5 is jpg, then 6 must be tif. That is 1-1.

In short, number of consecutive jpf files must be equal to number of consecutive tif files. And these must be together.

And if the order is not like the one above, then show error.

Re: How to check if extensions follows up in a list?

AFAIK you just need to set up some loops wisely. Here is a bit of quick and dirty approach I could think of:

List <string> s = new List <string>();
       s.Add("jpg");
       s.Add("tif");
       s.Add("jpg");
       s.Add("tif");
       s.Add("jpg");
       s.Add("jpg");
       s.Add("tif");
       s.Add("tif");
       s.Add("jpg");
       s.Add("tif");

       bool breakFor = false;
       int togetherCount = 1;
       for (int i = 1;i < s.Count -1;i++) {

         if (s[i] == s[i - 1]) {
           togetherCount++;
           continue;
         }
         else {
           int count = 0;
           while (count < togetherCount) {
             if (!(s[i + 1] == s[i + count])) {
               if (togetherCount > 1) {
                 MessageBox.Show("error");
                 breakFor = true;
                 break;
               }
             }
             count++;
           }
           if (breakFor) {
             break;
           }
           else {
             i = i + togetherCount;
             togetherCount = 1;
           }
         }
       }</string></string>

It might not be correct but good to start off I guess.

I would say, debug the code and find where you are wrong. Get hold of the logic and you will be done.

Matjaž Grahek wrote:

One thing I can figure out is you need to remoe this + 1. I have not debugged the code just read it so I may go wrong.

In today's pseudo-language that would be:

filelist=getAllFilenames()
filelist.Sort
diff=0
foreach(file in filelist) {
  if (jpg) diff++
  else diff--
  if (diff<-1 or diff>1) error
}

Two remarks:

1. to get a natural sort order for the file names, same as Windows Explorer does, you would need to use Explorer's code, i.e. use P/Invoke and the prototype:

[DllImport("shlwapi.dll", CharSet=CharSet.Unicode, ExactSpelling=true)]
private static extern int StrCmpLogicalW(string s1, string s2);

Of course if the name part is just a number, you could use int.Parse and sort based on the outcome.

2. I cannot imagine where and how your requirement could ever have a useful application.

If its about Windows Explorer than I think its not possible. The sorting is simple as its string...
Why error occur, if you check the extension...or I might not get your question

Matjaz-xyz12-Mar-09 0:22

Re: How to check if extensions follows up in a list?

12-Mar-09 0:22

It doesnt concern explorer.

Basicly, the intention of this application would be to check if JPG files have their duplicate TIF files.

If it would be just 1-1, then i could do it... but i cant figure this one out.

And what i ment by an error was to put as an output - in which folder the files dont match.

Matjaž

Xmen Real 12-Mar-09 0:27

Re: How to check if extensions follows up in a list?

its simple then...

try this

bool Test(string dirPath)
{
    string[] filePaths = Directory.GetFiles(dirPath, "*.jpg");
    for (int a = 0; a < filePaths.Length; a++)
    {
        if (!File.Exists(Path.Combine(dirPath, Path.GetFileNameWithoutExtension(filePaths[a]) + ".tif")))
            return false;
    }
    return true;
}

Matjaz-xyz12-Mar-09 0:30

Re: How to check if extensions follows up in a list?

12-Mar-09 0:30

Umm not duplicates :/ sorry... just... the follow up files.
1.jpg has his own tif, but with a different name. example... 3.tif, because there is another 2.jpg before.

Re: How to check if extensions follows up in a list?

In that case, just get the count of files with JPG and count of files with TIF and they must be equal.

Dump the code I had posted.

I already thought of that - but it is definitly a no-go. Why? Well, maybe there are some files which dont have their tifs, but some tiffs dont have their jpgs - and the count may match.
