Asp.net - Method For Attaching A Single Key/value Pair Attribute To An Enumeration?

May 4, 2012

I'm trying to figure out what the best method is for attaching a single key/value pair attribute to an enumeration where the key is my MerchantId and the value is the corresponding TransactionKey. What I currently do is put a comma delimited string into a StringValueAttribute class:

Public Enum Merchants
<StringValue("coke,faj80785hq+faf=-1=-jfa+">
Coke = 0
<StringValue("pepsi,adfji=-901jnas++fdj98ua")>
Pepsi = 1
<StringValue("drpepper,jk878-=+9kdkdja0=a=f--daj")>
DrPepper = 2

[Code]...

Is this the most efficient way to do this? Instead of StringValueAttribute, what about creating an attribute using a Dictionary(Of String, String) since it is a key/value pair list? Or String Array or List? Maybe something in LINQ?

Obtaining Name/value Pair Of Enumeration With LINQ [VB 2010]?

Jul 23, 2009

I'm trying to obtain name/value pair of enumeration typed into text box with LINQ. It's OK with name, but when LINQ reaches values, it throws error: "Conversion from string "Black" to type 'Integer' is not valid". I have read that if I want to obtain a value, then I gotta use conversion function.

Here's code (button's Click event):

Private Sub GetEnums(ByVal sender As Object, ByVal e As RoutedEventArgs)
lstEnums.Items.Clear()
Dim typeName = Type.GetType(txtEnum.Text)
Dim enums = From en In typeName.GetEnumNames

.net - Working With The ObjectQuery Single Enumeration Challenge In Linq-To-Entities Entity SQL?

Dec 30, 2011

I'm working on modifying this example:

Using advWorksContext As New AdventureWorksEntities
' Call the constructor that takes a command string and ObjectContext.
Dim productQuery1 As New ObjectQuery(Of Product)("Product", advWorksContext)

[code]....

An ObjectQuery can be enumberated only once. (Subsequent attempts at enumeration throw an exception.) The enumberation takes place in the for each statement. The problem is that if the query is empty attempting a For Each will throw an exception. But if I check for a count:If productQuery1.Count > 0 Then . . .

That eats up my one chance at enumeration. I could nest the For Each in a try/catch block and throw away the empty query exceptions, but that's ugly.

Method Not Intended For Code Attribute?

Feb 6, 2012

I have a couple of shared methods in my app which are intended to be used with ObjectDataSource's (and other reflection based objects). They handle a lot of automatic parameter checking, filtering, etc. They are, however, all one time use methods (they rebuild everything on every call). It would be much better for someone writing code directly to call the instance methods so that all the filtering, etc, is stored between calls.Is there an attribute I can add to my methods to indicate this? The best would be if it would prevent the method from being called without reflection. Second best would be to issue a warning that the method is being used wrong.[code]

Get The Next Item From A Value Pair?

Jun 18, 2009

The following code checks each sentence in the listbox and if certain conditions are matched it add a piece of data to the list new question. Each input from the user is checked against each sentance in the listbox and if a match is found (based on the conditions) only then the data is added to the list and the loop exits. My problem now is that for each itteration cycle In_dep_token_pair.Key and trigger_dependency_token_pair can not be Subject and DirectObject at the same time. Is there any way to test for the next item in the keyvaluepair within the same itteration cycle? Something like trigger_dependency_token_pair(current item).Key = "Subject" and trigger_dependency_token_pair.key = "DirectObject".

If (Input_pair.Key = predicate) And (In_dep_token_pair.Key = "Subject" And trigger_dependency_token_pair.Key = "Subject") And _

(In_dep_token_pair.Value = trigger_dependency_token_pair.Value) Then
If (In_dep_token_pair.Key = "DirectObject" And trigger_dependency_token_pair.Key = "DirectObject") Then
If (In_dep_token_pair.Value = trigger_dependency_token_pair.Value) Then

Multiple Name/value Pair Cookie?

Jun 22, 2011

In my VB.NET code behind, I've created a multiple name/value pair cookie like this:

Dim UserCookie As HttpCookie = New HttpCookie("UserInfo")
UserCookie.Values.Add("UserNumber", Me.UserNumber.Text)
UserCookie.Values.Add("Password", Me.Password.Text)
UserCookie.Values.Add("UserName", Me.UserName.ToString)
Response.Cookies.Add(UserCookie)

Now, what I need to do (somehow) is read that 'UserInfo' cookie in javascript and be able to extract those values at will. Most of what I'm finding out there doesn't quite do what I need to do.I'm trying to do something like this:

var MyValue = ReadCookie("UserInfo", "UserName")

And MyValue would equal whatever the user had typed into the textbox.

VS 2005 : Key-value Pair In Combobox?

Jan 27, 2011

Normally when I populate a combobox I do so by binding it to a datatable and assigning a display member and value member. I would like to do the same thing by adding pairs of items in code.I tried using a key-value pair, but that didn't work. The combobox displayed both the key and the value. I would like to have it just display one of the values and leave the other one invisible to the user, but available to me as a key.I thought about creating a custom class with two properties - one to use as the display member and the other to use as the value member. But before I re-invent the wheel I thought I'd check to see if there's already something there in the framework that I'm missing.

Save And Retrieve A Key / IV Pair Securely?

May 17, 2010

I'm using VB.Net's RijndaelManaged (RM) to encrypt files, using the RM.GenerateKey and RM.GenerateIV methods to generate the Key and IV and encrypting the file using the CryptoStream class. I'm planning on saving this Key and IV to a file and want to make sure I'm doing it the right way. I am combining the IV+Key, and encrypting that with my RSA Public key and writing it out to a file. Then, to decrypt I use the RSA Private key on this file to get the IV+Key, split them up and set RM.Key and RM.IV to these values and run the decryptor.

Is this the best method to accomplish this, or is there a preferred method for saving the IV & Key?

Take Each Pair Of File (the .mp4 And .srt Files) And Put Them In The HD Folder?

Mar 25, 2012

I have lots of TV Shows on my Hard Disk and every week I update that HD with the new episodes that have aired (I also download the .srt - subtitles - files) .

To do this, i have to take each pair of file (the .mp4 and .srt files) and put them in the HD folder (Ex: E:Tv ShowsDr HouseSeason 8). I have to do this lots of times and I waste several time to do this..

So, I was thinking, why not making a VS application to do this job?

I select all my .mp4 and .srt files from the week (witch are contained in a folder) and i drag them into my application witch should check the names of the files (they both have the same nome, Ex: House.S01E01.mp4 and House.S01E01.srt) and, by the first name ("House") search a hard drive witch I choose, and move my selected files to the "House" folder (where I have all the seasons of the Tv Show).
