I'm using a NameValueCollection that I'd like to sort the keys on, just not sure how. The keys are basically a 24hr time stamp.
Dim matched As New NameValueCollection
matched.Add("0010","string1")
matched.Add("1545","string2")
[Code].....
Instead of:
NameValueCollection nvc=new NameValueCollection();
nvc.Add("A","Alpha");
I want to do:
nvc.Add(somevar, "Alpha")
Is there hashing going on against the key?
I have tried.... somevar = """ & myvar & """ and every other thing I can think of...
When adding to a NameValueCollection you normally would do this:
nvc.Add("SOME LITERAL STRING", "MY VALUE")
but if you dont know the first parameter until you read it in from a file then you would want this:
nvc.Add(myVar, "MY VALUE")
this does not work! The NameValueCollection parameters SAY they want a string, but they really don't, they want a "Literal" sting.
So, the question is: How do I pass a variable string to the first parameter?

View 4 RepliesI'm trying to sort a range in excel 2007, copy it and export it to another workbook. I can get as far as selecting the range but, I get lost after that...I have searched a lot of threads but, just can't seem to find one that give me an exact answer.
View 4 Repliesto something that sure is really simple. If i have two textboxes. Textbox1 is where you type in the text and textbox2 sorts out the text. Lets say i type in a bunch of letters and numbers "random2random1random3" then sorts it out, so textbox2 only shows the numbers
View 6 RepliesI am trying to sort an array of ListViewItems, here is my code for setting is up:
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Apps(), Owners() As String
Apps = {"App2", "App1", "App4", "App3", "App5"}
Owners = {"AOwner2", "BOwner1", "COwner4", "DOwner3", "Owner5"}
Dim ListViewItemArray(Apps.Count - 1) As ListViewItem

I know I can have the ListView be sorted but I want the item "All" to stay at the top. I have tried sorting the array with:
vb.net
Array.Sort(ListViewItemArray)
But I get this error: "Failed to compare two elements in the array.".
I also tried:
vb.net
ListViewItemArray.Sort()
But it says there is invalid number of arguments. Is it possible to sort this array or is there an easier way to accomplish what I am trying to do?

I have data in a DataSet and want to extract 3 fields from each row in the DataSet.
Field1 = String
Field2 = Date
Field3 = Time
I then want to add all the Field1 strings to a combo list box, sorted by the dates and times in Field2 and Field3.
Is there an easy way to get the data from the DataSet in a Sorted order?
i.e. Equivalant to saying "SELECT [Field1] From [Table] ORDER BY [Field2], [Field3]" in SQL.

I've got a datatable with a DateTime field that I want to sort using a DataView. I only need the Time part of the column though, and not the date. I can't get it to show just the time and not the date as long as its a DateTime column. I know I could convert it to a string to get the time, but then it wont sort correctly.

I have a WPF ObservableCollection which is bound to a ListBox and I have a Sort() method which when called will convert the ObservableCollection to a List(Of T), and undertakes a sort based on a date/time column within the collection.
The data is sorted, even when new items are added to the ObservableCollection, however the date/time isn't being correctly sorted. The data is sorting based on the date however it is very much random when it comes to the time portion. The following is an example of the outcomes I am experiencing:
[Code]...
Is there anything that I am doing incorrectly in this method that would cause the time portion not be included in the sort? Is there a better way of doing a sort?
I have a DataTable in a DataGridView, one of the columns has data that I want sorted. I can click on the column header to sort it and it's fine. The problem is that I don't want that column sorted automatically when some of the data changes in it. I want it sorted only when I click on the header.
View 3 RepliesI have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.The code that I am using for the Device response capture, etc is :-

I am currently writing a bit of software for myself and need guidance.
I have a datagridview on a form with a date column. (column0)
I am trying to sort this by date desending but it will only sort by the day (dd) and not the whole date (dd/mm/yyyy) which leaves the months unsorted.

I have a Datetimepicker, when i select a date it brings up in a listbox all the files created on that day but in no particular order. So i wanted it sorted by when they were created (not to fussed either ascending or descending). i tried using the code below with no luck, This adds multiple of blocks of the same files on the selected date

I am performing some filescans in a directory where I always neither get ascending or descending order of filenames. What I currently have is a logical order, but what I want to make of it is an ascending order.
[Code]...
I have a program which is made with 12 labels, the first set of six are randomly generated and the second set are values obtained from the first set and the user has to choose in ascending order the numbers on the first set.The values chosen will be trasferred to the second set and then with a "check" button that set of labels have to be rearranged and compared to the user input.If the user for example manage to choose the right order, he will obtained a 6 of 6 and he will recieve a message.My problem is on the rearrage and compare part.
The code I made is very simple but is not working, basically it only check if the next value is smaller that the previous and changed its back color according to the case.
Here the code:

In the following code all goes well until the .Sort line. Then I get an error which says, "The sort method is not valid.

The Range is Selected ok and the Excel data are pasted from the clip board ok. Then I get the error and no sort occurs.
