In other words the values of the last row used are stored in every key, value dictionary combination. How do you prevent this from happening? It is clearly associated with the use of the temp variable, as the dictionary changed as the temp variable changes. Is there a way to only copy the values from the array rather then associate the dictionary with the changing values of the array?
I am developing a web mapping application intranet from our company. And I am creating add polygon function on the map. I use AspMap, Vb.net and sql server. So when user click a button for add new record therefor out the web form input data attribute. When i run the application I get trouble like this Incorrect syntax near '?' My code is:
Private Sub AddNewShape(ByVal checklist_id As String, ByVal type As String, ByVal shape As AspMap.Shape, ByVal address_area As String, ByVal dmz As String, ByVal customerid As String, ByVal source As String, ByVal area As String, ByVal instalatur As String, ByVal developer As String, ByVal data_received As DateTime, ByVal doc_data As DateTime, ByVal datereport As DateTime, ByVal remark As String)

I have a struct setup like the following[code]...
I then loop through a counter and add each PersonInfo object to the Dictionary. The Primary defaults to false if the Code is already in the Dictionary, but if it has not been inserted into the Dictionary, I want to set the Primary to True. It would be easy to check if the Code was the key, but I can't because the Code is not unique.
What I would like to do is be able to take a Dictionary of key value pairs and make the key the name of a variable and the value the value. From searching the net seems to be very vague on whether this is possible.

So I had a smart idea to make a dictionary with all my variables so I could save them easily in chunks. This includes String, Boolean and Integers. When I was in Framework 3.5 I only had a few warnings about stuff that I didn't have coded in, but now in Framework 4 I am maxing out all my warnings with Implicit conversions. Personally I don't want to go to every number and put quotes around it put quotes around "True" because then it may change the method.
Public Function loadGeneral(ByVal fName As String) As Boolean
Dim tempDict As New Dictionary(Of String, String)
For Each kvp As KeyValuePair(Of String, String) In GeneralSettings
Dim v1 As String = kvp.Key
Dim v2 As String = QuizZing.My.Settings.GetSetting(fName, v1)

I want to group items from a linq query under a header, so that for each header I have a list of objects that match the header title. I assumed the solution would be to use ToDictionary to convert the objects, but this allows only one object per "group" (or dictionary key). I assumed I could create the dictionary of type (String, List Of()), but I can't figure out how to write it. As an example I have written a simplified version below.

I have created a class with a function in it. I have a collection of data I want to pass back. I tried an arraylist first. Now I am trying to use a dictionary. My problem is that it creates the dictionary ok, but I am only get the last row of data from my

I have the following object:
countDictionary As Dictionary(of Category, Dictionary(of Date, Integer))
The Class has a Enumeration Property. For the purposes of demonstration, I'll call it MasterCategory.I have been trying to get out an object that looks like the following:
groupedCountDictionary As Dictionary(of MasterCategory, Dictionary(of Date, Integer)
The best result I could get was:
Lookup(of MasterCategory, Dictionary(of Date, Integer))
From:
countDictionary.ToLookup(Function(o) o.Key.MasterCategory, Function(o) o.Value)
Which results in a IEnumerable (Of Dictionary(of Date, Integer)) for each MasterCategory value.However, I need that IEnumerable of Dictionary flattened to one dictionary with all the integers summed (total counts) for each date. I then tried to use various selects and group bys (from numerous stackoverflow posts) to "flatten" it, but my efforts have fallen short.
Current Code
[Category Class]
- MasterCategory As Enum
- Name As String etc

I have a particular link that I'm trying to convert to an ASP:LinkButton place holder so that I can control it's visibility based on the user type:
<asp:LinkButton id="linkColumnsSelect" runat="server" Text="Select CSV Columns for Export" Href="javascript: void(0)" Visible="True" />
I was able to remove the PostBackUrl by adding "javascript: void(0)" to the Href property, but now I have the problem of getting a real ID that I can use in javascript. As it currently stands, this creates an ID for the item of ctl00_ContentPlaceHolder1_linkColumnsSelect, however I need that ID to be "linkColumnsSelect" on the client side and still work server side (for jQuery coding reasons that involve looping). Is that possible? Or do I just need to adjust my jQuery to account for the placeholder segments of IDs?
I have a page that includes javascript which I only want to run under certain conditions. To do this I have placed the scripts into an asp: placeholder.This actually seems to work but when I run a debug on the page I get the following warning.Element 'placeholder' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.If I move the placeholders into the body of the page the warning goes, but that means I'm left with scripts in the body which I also want to avoid. Does anyone have any hints on the best practice for this scenario? [code]

View 1 RepliesI have created a Dictionary class (MyDictionary for the example). I am currently trying to pass MyDictionary into a function, filter it into a new instance of MyDictionary and pass this new instance into another method.

I'm working with a website written in aspx.net over vb. I have a placeHolder, and I create a table of names inside this PlaceHolder, each name has an HtmlInputCheckBox next to it.

I've done asp.net exclusively so long, and now I have to convert a small web app to a desktop app.
At one point in the web app, I dynamically generate a table of data and add it to a placeholder control.
I'm not sure how that would be done on a desktop app. Can anyone suggest a control or 'windows' way of doing that.
I have a UserControl that has a simple repeater inside. It has a property called data which when passed into the control populates the repeater using the standard databinding.
