Example Of A Customer Binary Serializer In .Net?
Apr 14, 2011So, I want to implement my own binary serialization. I'm looking for some examples to head me in the right direction.

View 2 RepliesI am creating a class that searches a binary file for a specific customer number. I am using a binary search that keeps on slicing the file in half until I find the customer number while is sorted. Once it finds it I am positioning it at the first instance of that Customer number as there can be multiple records with the same Cus Number.
Now here is my question. I now need to loop through this Customers records and do some data base searches. Since I want to make my class as generic as possible what should I pass back to the calling class? An Array with all their records. If I do this I have to loop twice, once in the class and once when it passes the array bac to the original calling class?

I have the following problem: I select a customer from a dropdownlist and then the gridview should load all items of all orders of that customer. I have the following query:
Dim allorders = From ord In db.Orders
Where ord.CustomerID = Convert.ToInt32(CustomerDropDownList.SelectedValue)
[CODE]..............
I also tried to modify the query as follows:
Dim orderitems = From oi In db.OrderItems
Where oi.OrderNumber = (From From ord In db.Orders
[CODE]...........
But this does not work. I just started using LINQ.

I have been googling this and have not come along a working solution for an entire day. I don't know anything about binary data types (as I've never knowingly used them) and I'm trying to write a binary value that I see in the registry, to the registry. Now, all I see is the following [shown below]... and if I try to pass that as a string to the RegSetValueEx in the WinAPI and of course it errors out...
I do not know what 'numbers' I need to pass into the lpData As Any, argument of RegSetValueEx (i tried a bit array) in order for it to come out as the following [shown below] in the regedit. I really have no idea, and my tests to place random numbers in the bit array just produce corresponding random "figures" as visible in regedit that I do not understand how to 'tie' them together logically. here is the culprit!

[code]A customer can not exceed a debt load of 36% of their gross monthly income including house rent or a mortgage.[code]I basically know how to code this. I get the information from the user (income, rent, and other monthly payments) and then ask if they have good, ok, or bad credit (this will be the percentage part) and I know mostly what to do, but the hardest part is the actuall coding part, basically the calculations part, im always confused on what to do, my example shows basically what to do and I know how to get the users info, but how to program the calculations, is where im also stuck at My example is (the money for the income, rent, and other monthly payments the user entered already)
1. If there monthly Income is:$2,000.00
2. Monthly Home Rent/Mortgage:$500.00
3. Other Monthly Payments (alimony, child support, student loans):$100.00
4. Then there allowable Monthly Car Payment:( 36% of 2,000 (income) = 720)( now I subtract debts 720 - 500 (rent) - 100 (other) = 120) :$120.00
5. Display Maximum Car Value (interest rate based on credit):Present Value Function (16% per year (this is where I check one of the boxes for the credit, which in this case its an ok credit), 6 years (I have to keep it at 6 years), 120 (this is the allowable monthly car payment) per month)So basically PV((0.16 / 12), (6 * 12), 120) : $5532.03.

It's a basic Access database driven e-commerce site. I have a home page, a products page, an orders page, an order confirm page, a shopping cart page and a view current orders page. The site uses an Access database with three tables. A Customer table, with all of the customer details, (FirstName, LastName, EmailAdd, CardNo, CardEx, SortCode, DeliveryAdd, Postcode)A Products table, with all the product information, (ProductID, ProductName, Price, ProductType, Images, ProductDescription). And an Orders table which contains CustomerID and ProductID.I've managed to get the orders page to work, this leads to the order confirmation page which displays the details the customer just placed.Here is what I have in the order confirmation page load event so far. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

This returns this error "Syntax error in FROM clause." I'm guessing my SQL code is wrong. I noticed when I placed the order in the order page it added an entry in the Access database where the generated CustomerID was 12 on the customers table and 4 in the orders table. Shouldn't these numbers be the same when they are generated?

View 9 RepliesI'm currently in the middle of attempting to create a query that will be used so that the application user will be able to search the a customers id number. I'm completely new to adding queries using the query builder so I've become slightly stuck on trying to get this to work corrently.
I have a database which is set up and in this case the table is called 'cid' which defines the customers id column in the database, this is a primary key and the column has a data type 'AutoNumber'. I've become stuck as I'm not sure what I would have to put into the filter to make this query work.

I have to calculate the maximum mortgage possible for a customer. If it is a single application, the customer can borrow up to three times their salary plus any savings and investments they may have.
If it is a joint application, the customer can borrow 3 times larger salary and 2 times the smallest, also borrowing against any savings and investments. In either case, the applicant is not allowed to borrow in excess of 90% of the purchase value of the property (including stamp duty and legal fees).
I have declared everything and done out the code, yet every time I calculate the max amount they can borrow, it comes up as 0. My code is below if anyone can spot problems.Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _

I working on a program that I am trying to create a customer data form.Along with the form I have their vehicles related to that record.Now I have setup a dataset in the form.I am pulling data from the database, however when I enter a new record on the customer part the customerID is in the running order, everything seems to be working on in this table.But when I create a vehicle for this customer I have a running vehicle id.Example: I have in the database 4 customers.IDs 1,2,3,4 customer 1 has vehicle ID1,2.customer 5 has a car there 1st car but the database gives is a ID of 3.I want this customer to ID 1 for car one.My problem might be because it was set in the database as Unique Identifier.Maybe I should make the license plate the unique identifier.
View 4 RepliesI am sure some of you have seen this project before. I need to create an application that queries customer name (first and last) and there addresses. I need more than that but once I figure what i am doing wrong with that, I should be able to figure out the rest on my own. I am using VS 2010. I can not figure out the proper syntax for String.Format. I can only get it to display the first and last names of the customers.This is the code I have so far:Public Class Form1
