If you want it

I need to sort the scandir(); results to be sorted by modification date. I've tried a few solutions I found here and some other solutions from different websites, but none worked for me, so I think it's reasonable for me to post here. What I've tried so far is this: function scan_dir($dir) { $files_array = scandir($dir); $img_array = array(); $img_dsort = array(); $final_array = array(); foreach($files_array as $file

Now I'd like the user to be able to sort by any column displayed in the grid. There is a way described on MSDN online which shows how to implement a custom collection based on BindingList<T> which allows sorting. But isn't there a Sort-event or something that could be caught in the DataGridView (or, even nicer, on the BindingSource) to sort the underlying collection using custom code? I don't really like the way described by MSDN.

Example: Integers are received/sent via network. There is a sufficient space on local disk for intermediate results. 回答1: Split the problem into pieces small enough to fit into available memory, then use merge sort to combine them. 回答2: Sorting a million 32-bit integers in 2MB of RAM using Python by Guido van Rossum 回答3: 1 million 32-bit integers = 4 MB of memory. You should sort them using some algorithm that uses external storage.

List<T> docs = GetDocsFromDb(...) I need to keep the same order in both collections, so that the items in List<T> must be in the same position than in the first one (due to search engine scoring reasons). And this process cannot be done in the GetDocsFromDb() function. If necessary, it's possible to change the second list into some other structure (
