May 11, 2012I'm using Entity Framework code first and pulling some data back from our database. In the table I'm accessing is 13 columns that store the number of a items a customer purchased per week for the last 13 weeks as a char field. I have no control over how this data is stored. I need to total the 13 weeks results together to get a combined total, so take week1 + week2 + week3.... = Total Items Purchased over 13 weeks.In SQL I'd just Cast the char to an Integer and add the values together.

Oct 6, 2011Im working on an Asp.net / VB.net website and coming from a C# / WPF background things are still a little new to me.

However in another method i need to be able to access this DataTable, yet whenever I do it always appears as nothing. Do I need to be storing this value elsewhere like in the session etc?
Best Method For Storing Values?
Feb 6, 2010Basically, I want to have a database that's lightweight and I won't need to install amillion other things on my clients computers for them to access this.I just need a simple method of reading and writing values so that they're not hardcoded into the program. I could do MySQL (which is what I'm very familiar with), but it doesn't need to be making calls remotely.

View 2 Replies.net - Storing An Object To Use In Multiple Classes?
Mar 23, 2010I am wondering the best way to store an object in memory that is used in a lot of classes throughout an application. We have multiple databases, 1 per customer. We also have a master table and each row is detailed information about the databases such as database name, server IP it's located and a few config settings.
I have an application that loops through those multiple databases and runs some updates on them. The settings I mentioned above are updated each loop iteration into memory. The application then runs through series of processes that include multiple classes using this data. The data never changes during the processes, only during the loop iteration.
The variables are related to a customer, so I have them stored in a customer class. I suppose I could make all of the members shared or should I use a singleton for the customer class? I've never actually used a singleton, only read they are good in this type of situation. Are there better solutions to this type of scenario? Also, I could have plans for this application to be multithreaded later.
Storing Multiple Arrays Into A List
May 11, 2011The scenario is:
1)A large 2 dimensional array (400,20)
2)The program needs to access particular chunks(for example (0,20) to (50,20)
3)The program will open multiple files and process each into it's own 2D array (400,20)
What I have right now is code capable of creating the array, but no way to store the array so that I can open a new file and process that data into another large array. Someone mentioned the generics List(of T) might be a good way to store each new array as you could use the Add function. I have done some research on the List(of T) class but I'm not totally convinced that is the way to go. I'm just looking for some direction as I've just started on .net this year.

Storing UserID And Password Values From MainString To Variables
Mar 10, 2009I have this string
mainString="/MyApp/ViewPage.aspx?userId=admin&password=1&id=975"
I am getting value in mainString using this code
Dim mainString As String = Request.QueryString("dest")
And I have two sting variables
1)strTempUsername
2)strTempPassword
In these variables I want to store userId and password values from mainString.
So for this requirement how I write logic in code
Dim arrArray() As String
'/MyApp/ViewPage.aspx?userId=admin&password=1&id=975"
strIndexq = mainString.IndexOf("?") ' Check QuestionMark Exist or not in mainString
If strIndexq > 0 Then
Dim strTemp As String
[Code] .....
Here I am getting userId and password but in this code I will get problem when after ? if userId and password starts wit capital letters and password maybe contain characters like "1&a"
And after getting userid and password. I want to remove userid and password from mainstring. So I want mainstring look like:

View 3 RepliesStarting Multiple Instances And Storing The Settings?
Jul 11, 2011I have a VB2010 application that must run as multiple instances on the same PC (it is a controlling/monitoring program of several devices, each instance of the program control one device)
Of course, the same application must save its own setting in different place, one for each device. For example, if I start the application for the device 3, I have to save the setting in a place marked as "3", in this way, when I start the application for device 4 it will load the settings for device 4 and not 3.
Of course all labels and similar stuffs must refer the starting device: i.e. the mdi caption must report "device 4", and so on...
In vb6 I created a shortcut with a command line and made my application accepting command line parameters.
In this way I could start the application passing the device number too. For example "myapp.exe 3" start my application for the device 3.
I stored all settings in several INI file, each one for a device: setting1.ini, setting2.ini, setting3.ini, ....
I was wondering if in vb2010 would be a better way to do that.
1. How could I start multiple instances?
2. How could I store the settings?

Storing An Object That Implements Multiple Interfaces And Derives From A Certain Base (.net)
Dec 7, 2010In .net, it's possible to use generics so that a function can accept arguments which support one or more interfaces and derive from a base type, even if there does not exist any single type from which all valid argument types derive. For example, one could say: Sub Foo(Of T As {IInterface1, IInterface2, SomeBaseType})(Param as T) And be allowed to pass any derivative of SomeBaseType which implements both IInterface1 and IInterface2. This will work even if SomeBaseType does not support Interface1 and Interface2, and classes which do implement those interfaces don't share any common ancestor that also implements them. This can be very convenient if one won't need to keep the parameter anywhere after the function has exited. Unfortunately, I can't figure out a way to persist the passed-in parameter in such a way that it can later be passed to a similar function, except perhaps by using Reflection. Is there any nice way of doing that?
The closest I've been able to come up with is to define an interface INest (perhaps not the best name-- thus:
Interface INest(Of Out T)
Function Nest() As T
End Interface
And for any interface that will be used in combination with others or with base-class "constraint", define a generic version as illustrated below:
Interface IFun1
' Any members of the interface go here, e.g. ...'
Sub DoFun1()
[CODE]...
A class which will support multiple interfaces should declare itself as implementing the generic ones, with itself as the type argument.
Class test123a
Inherits sampleBase
Implements IFun1(Of test123a), IFun2(Of test123a), IFun3(Of test123a)
End Class
If that is done, one can define a function argument or class variable that supports multiple constraints thusly: Dim SomeField as IFun1(Of IFun2(Of IFun3(Of sampleBase)))
And then assign to it any class derived from sampleBase, which implements those interfaces. SomeField will implement IFun1; SomeField.Nest will implement IFun2; SomeField.Nest.Nest will implement IFun3. Note that there's no requirement that IFun1, IFun2, IFun3, or sampleBase share any common derivation other than the generic interfaces inheriting from INest(Of T). Note also that, no matter how many INest-derived interfaces a class implements, it only needs to define one implementation of INest(Of T).Nest. Not exactly beautiful, but there are two nice things about it: (1) any concrete class which in fact implements the necessary interfaces can be assigned directly to a field declared as above, without a typecast; (2) while fields which chain the types in a different order are not assignment compatible, they may be typecast to each other. Is there any better way to store something in such a way that it's "known" to support multiple interfaces and derive from a certain base type? Given that one can write such code in a type-safe manner, it would seem like the .net 2.0 CLR could probably support such a thing quite nicely if compilers offered a little assistance.

Exclude Multiple Values In Sum Depending On Values In 2 Columns In SSRS 2005?
Apr 21, 2009I have simple columns and their respective sums. However, I exclude 1 particular value from each sum, like so [code]...
Now I need to exclude another value ("Awaiting Progression") from a second column called "PROGRESSION".
Since I already exclude value based on 1 column called CATEGORY, how do I change my =Sum(Code.ExcludeOthers(Fields!CATEGORY.Value,Fields!ACTION_PLAN_NEW.Value)) to exclude a value from the PROGRESSION column if it's = ("Awaiting Progression") ?

VS 2010 : Finding And Storing A String?
Jan 8, 2010I'm obtaining data from a StreamReader.My StreamReader is called "reader" and I'm reading the stream with "responseOutput" like this "responseOutput = reader.ReadToEnd()" And in that bunch of text that I receive I want to FIND and EXTRACT a piece of text and then STORE that extraction in a variable of String type.Here is part of the code I'm referring to:
Dim response = request.GetResponse
Dim responseOutput As String
Dim reader As StreamReader
reader = New StreamReader(response.GetResponseStream())
responseOutput = reader.ReadToEnd()
And here is the text or data that I'm receiving (what I'm about to show you is the result of a "MessageBox.Show(responseOutput)":

And all I want to do, is to extract a specific part of that text, which is the "PhotoId" value (I highlighted it in red), in this case the value is "8262715", and then store it in a variable (I know how to do that I just need the value).The text or data I'm receiving changes only the PhotoId everytime it's requested.
