sorting files retrieved by OpenFileDialogI'm not happy with the order in which OpenFileDialog retrieves multiple
selected files. I want them in Date order, oldest to newest, but by default they come in by filename, last to first. The only property that seems relevant is Sort, and all that does is invert the filename order. I need Date order. I've searched for an answer but nothing has come up. Any ideas? See if the following helps
NOTE: Havent compiled it, so might have typo or syntax errors ' Comparer Class Public Class CompareFileDates Implements IComparer Function IComparer.Compare(ByVal a As Object, ByVal b As Object) As Integer Return DateTime.Compare( System.Io.File.GetLastWriteTime(DirectCast(a, String)) , System.Io.File.GetLastWriteTime(DirectCast(b, String)) ) End Function End Class ' Code to sort the files by date Array.Sort(files, new CompareFileDates()); HTH rawCoder Show quoteHide quote "Randall Arnold" <RandallArn***@discussions.microsoft.com> wrote in message news:A12E5406-9F66-42D1-80B2-F726EC92EFEC@microsoft.com... > I'm not happy with the order in which OpenFileDialog retrieves multiple > selected files.

That's foreign functionality to me and I received a number of errors after inserting the code so I'm obviously going to have to play with it a bit. I appreciate you getting me started!

Any ideas? to one array as FileInfo(path) and the other array add FileInfo (path).DateCreated for each item returned, then do [Array].Sort (dateArray,fileInfoArray), the resulting fileInfoArray will be sorted by dateArray. More on this here:http://msdn.microsoft.com/library/default.asp? url=/library/en-us/cpref/html/frlrfsystemarrayclasssorttopic.asp The other way would be to implement IComparer in a class (which is only one function) throw all the selected files in an array as FileInfo's and then [Array].Sort(fileInfoArray,ComparerClass) More info here:http://msdn.microsoft.com/library/default.asp?url=/library/en- us/cpref/html/frlrfsystemcollectionsicomparerclasstopic.asp Thanks, I'll try that as well.
Boggles my mind that MS didn't include a property for this on the FileOpenDialog.

could ever think of even if it hasn't been thought of yet.". The purpose of the FileOpenDialog has been well established for many years. It is to return 1 or more filenames. It is not to return 1 or more objects representing information about file(s). The whole concept of a framework is a foundation upon which you build. MS have provided the foundation and it's up to you to build upon it to achieve the desired results. In a nutshell, that's what programming is.

No, my question
was NOT in the manner you allege; I simply asked about ONE property, whch in no way leads to your hyperbolic sarcasm. And while the functionality of the dialog control may have remained static for many years, that's not a reason for it to always remain that way. I note that the .NET framework both added to and took away from many controls. Obviously MS doesn't consider the property set to be cast in stone. In my *opinion* (which is just as valid as yours, by the way), the functionality I wished for would be easy enough for MS to implement and would simplify what is obviously a cumbersome workaround; note that none of the suggestions mentioned here has worked for my purposes. If you don't have anything productive to contribute to my queries or comments, I ask you just not add anything at all. Thanks.
