Body
This could be cleaner, but it works: <pre><code>Dim fruits As New List(Of String) From { "apple", "orange", "pear", "banana" } Dim input As String = "a,p,l,e,r" dim inputLetters = from letter in input.Replace(",", "") group by letter into Group select group.first, Group.Count dim result = fruits.where( function(fruit) dim fruitcounts = from letter in fruit group by letter into Group select group.first, group.count dim res = from fc in fruitcounts, inputs in inputletters where fc.first = inputs.first andalso fc.count <= inputs.count select fc.first return res.count = fruit.count end function ) </code></pre> edit - I removed some unneeded order by clauses, and simplified the grouping edit again - after some more thinking, here's a version that has more lines, but is much clearer and better factored: <pre><code>Sub Main Dim fruits As New List(Of String) From { "apple", "orange", "pear", "banana" } Dim input As String = "a,p,l,e,r" dim matchingFruits = from fruit in fruits where CanBeMadeFrom(fruit, input) End Sub Function StringToFrequencyTable(input as string) as Dictionary(of Char, Integer) dim freqTable = from letter in input group by letter into Group select letter, Group.Count() return freqTable.ToDictionary(function(g) g.Letter, function(g) g.Count) end function Function CanBeMadeFrom(candidate as string, letters as string) as boolean dim inputLetters = StringToFrequencyTable(letters.replace(",", "")) dim IsCharInFrequencyTable = function(x) (from entry in inputLetters where entry.Key = x.Key andalso entry.Value >= x.Value).Any() return StringToFrequencyTable(candidate).All( IsCharInFrequencyTable ) end function </code></pre> If I did anything else to this, I would make CanBeMadeFrom and StringToFrequencyTable into extension methods.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
