Architecture - Apply The Correct Data From The GUI To The Parameters For The Rule And Execute The Rule

Apr 6, 2011

I have a very simple Business Rules Engine that has only three methods. One gets all the rules for the current operation, one will retrieve a list of parameters for the rules, the last applies the rules. The rules are stored in the database as user defined functions using parameters. The client will call the BRE pass in the operation and a Lot Number and the BRE checks for any rules that apply to this operation for this Lot. The client gets a list of rules that apply (the names of the corresponding UDF's in the database) and at which step in the operation the rule applies. When the material gets to a step that has a rule, it calls BRE to get parameters for the UDF for that operation, fills in the parameters with data contained in the GUI and calls the BRE to apply the rule with this lot's specific data. Multiple lots can share the same rule that is why there are parameters for the UDF. This all works well. However, this is assuming we have a set number of rules for each lot at each operation. If the lot needs a new rule applied at this operation we have to add a new rule and corresponding UDF into the BRE database. This is not a problem, the client will now see two rules, however, it only knows how to apply the parameters for the first rule, and there is no code for applying the parameters for the second rule.

For example: Rule 1 states that only the same Lot number items can be put into a carton. So the UDF expects one parameter called LotID and one parameter called Carton ID. It runs the rule (UDF) with these parameters and checks to ensure the lots match. Now the Lot requires a second rule: Only 25 items can be packed in the carton. We create a new rule and corresponding UDF, but this rule has the CartonID and a quantity associated with it.

The GUI can handle Rule 1 because it knows how to apply the correct data from the GUI to the parameters for the Rule and execute the rule, so LotID from the GUI = LotID in the parameter name in the UDF and CartonID from the GUI = CartonID parameter name in the UDF. Now there is a new rule, the GUI sees this new rule, gets the parameters, but has no way to applying the quantity to the new parameter to execute the rule without having to change the GUI. We don't expect there to be many rule changes, however, when they do occur we don't want to have to recompile the GUI every time. Does anyone have any suggestions on how to create a class that could determine the how to apply set the correct parameters? We have thought about a table in a database that maps the parameter names in the UDF with parameter names in the GUI so when we add a new UDF we update the table with the corresponding data from the GUI. That could work but may get cumbersome and would require us to make sure that, that table is kept current. Another suggestion was to name the parameters in the UDF the same as the parameters in the GUI, but this too, would require us to maintain the names in two locations.

Asp.net - Create A LINQ Statement Where The Table Name (FROM) And Column Name Is Variable?

May 11, 2012

In my programming task I've gone down a dark alley and wished I hadn't, but there is no turning back now.

I'm building up a SQL statement where the table name, column name and id value are retrieved from query string parameters i.e. ("SELECT [{0}] FROM [{1}] WHERE [Id] = {2};", c, t, id)

But it isn't as bad as it looks, I'm protected: Only authenticated users (i.e. signed in users) can execute the Page_Load I'm checking that both the table and the column exists beforehand (using GetSchema etc.)I'm checking that the Id is an integer beforehand All my tables have Id columns The database connection is reasonably secure

Creating VB Code To Increment The Number Of Fields In An SQL Create Table Statement

May 8, 2012

I have an SQL statement which i need to code in vb:

CODE:

Notice the fields prodno1 and prodno2 in the table structure.. this is part of a number of sql statements i need to run and put inside a loop. my problem is i want to automatically use this same code such that on the next loop, this sql statement is going to be:

CODE:

Note that in this "2nd loop"

- the table name is now r3 from r2 in the first SQL statement
- there are now prodno1, prodno2 and prodno3 instead of just prodno1 and prodno2
- in the WHERE clause, the p.prodNo becomes p.prodNo2

And so on and so forth.. so for the 3rd loop

- there's going to be r4
- there's going to be prodno4
- in the WHERE clause i will use p.prodNo3

Using Integer.TryParse For Validation An If Statement?

Feb 12, 2012

this is for homework but I have 90% of the project done, I just need to finish the data validation portion of the code.This is what I have for the calculate click event:

Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Dim intInputA As Integer
Dim intInputB As Integer
Dim intInputC As Integer

[code]....

My Problem: I am using the Try parse to validate weather the inputA(B)(​C) is an integer or not, if it is an integer, i want it to move to the nested if and validate that it is a positive number, and show the error message in the label if it is not. If it is not a number at all i want it to show another message in the label. The problem that I am getting is that even if i put in a letter for the input it does not catch it and it continues on to the select case, which comes out 0.

Declarative - Enforce Type Alias In .NET?

Apr 6, 2012

How might one go about aliasing a type in VB.NET or C# such that when the alias is used as an argument type in a function, accidentally using the not aliased type is an error?

i.e.

Imports AccessSpecifier = System.String
Module Accessors
Delegate Function IoOper(ByRef strm As System.IO.Stream) As Action

[code]....

Overall, I'm wanting the IDE to force me to know what I'm doing if I'm throwing Ints around to mean Flags, or States and Strings around to mean Names, Propertys and Records.

Create FK To Model, From Aspnet Forms Validation Tables

Jan 17, 2012

I've recently created a MVC 3 ASP.net application (using VB). I have also created forms validation by running aspnet_regsql. I used this to create the table in the same database as my application uses. I am trying to work out how to create a new model, with a FK from the Users table. Do I have to reverse engineer the validation tables to create models in my application? right now, the tables only exist on the SQL 2008 database, as they were created by running the aspnet_regsql command, and do not exists as models in my ASP.net solution. Here is the code I have now, for a model I would like to add a FK to (as a one-to-many relationship):

Imports System.Data.Entity
Imports System.ComponentModel
Imports System.ComponentModel.DataAnnotations

Create Table Button Which When Clicked Creates A Table In Sql Server?

Sep 17, 2009

I am working with a Vb.net 2005 application. On the application I have a Create table button which when clicked creates a table in Sql server with the code shown below;

Code: Private Sub BtnCrtTable_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCrtTable.Click

[Code]...

This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.

Therefore, initially I created an open dialogue to browse for the text file and store the path such as E:Datafile est.txt, in a TextBox1 visible at run time. Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.

How To Merge Two DataSets On Specified Rule

Apr 13, 2010

I'm trying to merge two datasets based on these rules:
1. With ds1 and ds2, If the Unique Key from ds1 is not found in ds2, copy it to ds2 and move to next row in the table, else, goto the next part
2. If the unique key in ds2 is found in ds1, check the DateLastEdited row.
a. If DateLastEdited in ds2 is greater then in ds1, copy the row from ds2 to ds1, else , do nothing

I'm just having trouble with the loops. Here's what I have:
Dim ds1 As DataSet = fillNetwork() 'this function fills ds1 with the dataset from a table found on a network
Dim ds2 As DataSet = fillLocal() 'this function fills ds1 with the dataset from a table found on local drive
Dim returnRows() As System.Data.DataRow = Nothing
For Each dtDs1 In ds1.Tables
[Code] .....
This bit of code is just trying to segregate the one that are in both tables from the ones that are just in one table.

Applying A Rule Set To Different Lines Of Text?

Apr 27, 2012

The general purpose of my application simply reads a line of text for example:

1. I have a printer issue
2. I have a software issue

I have a rule set as follows:

'Define the class 'Printer' with 14 values as a string...
Dim Printer(13) As String
'The string 'Printer' gets assigned a value, this is repeated another 13 times...
Printer(0) = "Printing"

[code]....

The code simply uses a number of keywords to detect if the issue is a 'printer', 'software', 'telephone',. or 'password' problem.I want to apply this rule set to 10 issues within the same rich text box, with the results sent to a text file. The exporting to a text file I can do, however the main issue is, i cannot read the lines individually.
