.net - Check Keyvaluepair Againt Existing Values In List Of Keyvaluepair
Aug 22, 2010
How can I check a new KeyValuePair against an existing list of KeyValuePair ? I want to compare for a condition to include or exclude the item. I am using vb.net 3.5
it is a nested For loop and I am deleting a datarow on the result of the condition
args = (existing list of KeyValuePAir)
For Each datarow As DataRow In ds.Tables(0).Rows
Dim args2 As KeyValuePair(Of Integer, Integer) = New KeyValuePair(Of Integer, Integer)(datarow.Item("Integer1"), datarow.Item("Integer2"))
what I want to do here is see if args2 is already contained in args if not I would delete the datarow , but I also need to search the datarow multiple times

I'm currently on a VB.NET project and wish to use a KeyValuePair to facilitate a reverse lookup. I've found a great example in C# here: [URL], however I am having a small problem converting to VB.NET (both manually and using a translator (online carlosag)). For example the syntax I would expect in the Add method is as follows:

To be able to sort a dictionary by value I'm using this code:
Dim idCurrentJobs As IDictionary(Of String, Int32) = New Dictionary(Of String, Int32)
'The string in the dictionary represents a jobname and the integer is a counter for how many jobs im currently are running in the application'
idCurrentJobs.Add("JobName1", 2)

This code:
vb Dim s As String = strContents '<a global variable) Dim currentPos As Int64 = 0 Dim endPos As Int64 = strContents.Length - 1 '// A dictionary, used to count the frequencies Dim characterCounter As New Dictionary(Of [String], Int64)() While currentPos <> endPos '//

Gives this error: Value of type 'System.Collections.Generic.KeyValuePair(Of String, Long)' cannot be converted to 'System.Collections.DictionaryEntry'.

I've never really used the Check List Box in the past, however, for the recent program I am developing, I am using this control rather than individual check boxes scattered across the form.Anyway, I want to be able to program through code which items get checked in this checked list box. Specifically, I have a variable that contains the text of each check box that I want checked.With a normal check box, I can simply say:
Dim strNames As String
strNames = "John Doe, Mark Johnson, Mike Brown, Cindy Smith"
If strNames.ToString.Contains("Mike Brown") Then[code]....

How can I get a new distinct list from an existing list using LINQ? This is what I have so far and it is not distinct but does give me a new list.
Dim tmpQryColumn = (From a In _allAudits
Select New CheckBoxListItem
With {.Id = a.AuditColumn, .Name = a.AuditColumn}
).Distinct()
_columnList = New List(Of CheckBoxListItem)(tmpQryColumn)

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

I am getting the check value correctly in the database using a Boolean.Here is one of the errors I am getting. Unable to cast object of type

I was working on a scenario where I have to add header to the Response Header.
I added a Response Header like this:- HttpContext.Current.Response.AddHeader("key1", "value1")
After some functional flow I required to add value to same "key1": HttpContext.Current.Reponse.AddHeader("key1, "value2")
thus value in Response Headers look like this:- key1 : value1, value2
I want to avoid the value2 addition to the same keyword key1.
I tried:-
If HttpContext.Current.Response.Headers("key1") Then
HttpContext.Current.Reponse.AddHeader("key1, "value2")
EndIf
But I got the error: This operation requires IIS integrated pipeline mode at HttpContext.Current.Response.Headers("key1")
I have IIS6 running. This [URL] says that it doestn't works if its not IIS7

I don't know if this is doable, maybe with Linq, but I have a List(Of MyType):
Public Class MyType
Property key As Char
Property description As String
End Class
And I want to create a Dictionary(Of Char, MyType) using the key field as the dictionary keys and the values in the List as the dictionary values, with something like:
New Dictionary(Of Char, MyType)(??)
Even if this is doable, internally it will loop through all the List items, I guess?

so i have this code which is trying to allow the user click the label (of which there are 26) and then decide whether the letter in the label matches the letter that has been generated in the radio button. I KNOW there is a more simplified to do this and much less code to write but i cant work it out. this is an image of what im trying to achieve but instead of buttons change those to radio buttons x 3.
