System To Calculate The Charges For Each Load That They Deliver?
Apr 15, 2012
The company needs a system to calculate the charges for each load that they deliver. The loads consist of up to 10 different types of goods. Each item has an associated delivery charge. The system will allow the user to select up to 10 lines of goods and a quantity for each line of goods. It should then calculate the total delivery charge. It must add 20% VAT to this net total and show the gross total as well. The system should show a total number of items as well as the delivery charge. It must recalculate in real time (i.e. as soon as a quantity is entered or changed the totals should recalculate). There should be a facility to enter the delivery date and address as well. The delivery date cannot be entered as a date that has already passed.

Is it possible to deliver an Excel Spreadsheet via an Web Service. I believe not as ASP.NET web services seem only to deal in Serializable elements which the excel binary format isn't (I think). If the Excel is saved in XML format will this work?
I have a number of reports that will be emailed, but the request has been put into allow these reports to be pulled via Web Services.

e to install small software (which i make for customer) but for installing that software, i have to install sql server 2005 as well on his system, while the customer system is not in a condition to support the sql server, because of low processing (mean to say that simply this is very heavy software and customer don't want to make his system slow).My question is that isn't there any way, through which he could use the software and he needs not to install sql server on his system or any other supporting software (its the demand of customer)..

I have finished coding an application which I designed for people working in my office. When I started to install the application to computers at the office, I realized that, in some machines, application doesn�t work properly. Although it worked for 15 computers perfectly, for 3 computers following error code is displayed:
System.IO.FileNotFoundException: Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.

I have this issue where for every 1% below a 95% threshold a charge of £67 is added. For instance if the percentage drops to 70% I would need a method of totalling the charge for every percent.
Would I need to use a Do....While loop then the if...then statements?

A parking garage charges a $2 min. fee to park for up to three hours.The garage charges an additional 50 cent per hour for each hour or part thereof in excess of three hours. The max charge for any given 24-hour period is $10. Assume that no car parks for longer than 24 hours at a time. Write a program that calculates and displays the parking charges for each customer who parkes a car in this garage yesterday. You should enter in a TextBox the hours parked for each customer. The program should display the charge for the current customer. THe program should ise the method CalculateCharges to determine the charge for each customer. Ise the techniques described in the chapter to read Double value fro a TextBox. [ You may need to use methods Convert.ToDouble and Convert.ToDecimal when doing calculations with the number of hours and charges]
Public Class ParkingGarageFeeCalculatorForm
Private Sub calculateButton_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles calculateButton.Click
Dim hoursParked As Double = Convert.ToDouble(hoursParkedTextBox.Text)

I am at a road block on how to print all of the items selected since last clear. A File menu should allow the user to print preview and print a document that contains the charges selected since the last clear including the total of all shipping charges selected When I click print preview I get the entire program screen, I need it to just show weight, zone and charges of everything I have selected.

I'm developing a small app to for a vehicle rental company. They require the app to print invoices for customers (fuel usage and etc) with charges. I was thinking of outputting row by row to a html (file) table and populating qty,amount,final amount etc programmatically. And letting the user view and print that html file.

I generate a print preview, the only thing is, if there is enough data to fill like 2-3 pages I don't know how to generate a new page. It only fills the first page and that's it....
Private Doc As New PrintDocument()
Private Sub btnPrint_Click(sender As System.Object, e As System.EventArgs) Handles btnPrint.Click[code].....
most of the code it's just pulling data from database and printing necessary charges to the invoice, but if the invoice is more than 1 page then I don't know what to do because it only generates 1 page.

It's a game that continues for a long time and isn't done in a hour, so it is pretty annoying that if the player re-opens the game he has to do everything over again. So, does anybody know how I can make a save/load system? Like that on the first form of the game there is a "Save" and "Load" button. If the player presses the "Save" button, the program automatically saves the progress of the player in a file somewhere on the harddisk of the player, and if the player presses "Load", the program automatically loads the file he saved, so the player doesn't have to start all over again.

I have a WPF application that has 3 projects in the solution. I have the main menu, which is the actual EXE, a reporting DLL and the application files DLL which both are a WPF Class Library. I'm getting the System.IO error when I'm trying to use a 3rd party reporting tool from in the application files DLL. I have the 3rd party DLLs referenced and are set to copy local in my application DLL. Everything works fine if i reference the 3rd party reporting tool in the EXE project but I don't want to do that. I want my DLL to be stand alone so someone else can reference my DLL without having to add anything but my DLL.

The way that reads to me, there is a problem with their .net framework? Am I correct, or is there a problem with my code? I can't reproduce the problem, and many other people use the application with no problems.

I created a SQL application that synchronises with a SQLCE database when loaded. Works fine on my Dev machine but produces the following error on user machines:
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Synchronization.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
File name: 'Microsoft.Synchronization.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91'
In my attempts to fix, I have:
1) Reinstalled SQL Compact Editon 3.5 on the client machines
2) Reinstalled .NET Framework 3.5
3) Installed Microsoft Sync Framework 1.0 (which puts the 'missing' DLL onto the machines).
This still fails with the same error.

We are using a web browser to show a pdf file located in a folder on the network. The code looks like this:
System.Windows.Forms.WebBrowser.Navigate(New Uri("\hostpath ofile.pdf"))
This works fine, but now I have to use a specific user to access this file and I don't know how to include the user name, password and domain in the URI. Is it posible to add user credentials to the URI? Can I use another variant of Navigate method to accomplish this?

I have an desktop application that references several dlls. All are targeted for .Net 3.5, x86. The applicaiton has been deployed for several years and was upgraded from visual studion 2008 to 2010 last year. I have made several changes to the app since then (as recently as last Thursday) with out any issues. Now, everything builds, but when I run the application, I get a type initialiazer error when one of the projects is loaded by the main application.
The error messsage is {"Could not load file or assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.":"System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"}.
There were no changes to this project since the last successfuly deployment last week, but today I am getting this error.

I've decided to learn Visual Basic .Net as this is what some of my colleagues work with, and this will allow me to work with them on projects.I have purchased Microsoft Visual Basic 2010 Step by Step and downloaded the sample files. When I am trying to debug the first sample application (a Windows form), it is telling me that it can't load System.Drawing V4.0.0.0. However, if I create a new Windows Form application (C# or VB.Net) this works fine.
I had a look at the References tab in the project settings and System.Windows.Forms is referenced, but the version referenced is 2.0.0.0. I have removed and re-added this reference and it stays at 2.0.0.0 and I still get the error.Does anybody have any ideas as to what may be going on?
