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.
View 3 RepliesI 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.
We have a rather large VB.NET accounting application that crashes occasionally for some customers. I have now been able to reproduce this particular almost 100% in my test nvironment using certain data. The crash happens when clicking a list box after printing a report. The form involved has a list box listing available reports. You select one or more reports from the list box and click the print button. After printing, if you click the list box again, the program crashes, with an exception that does not seem like one VB.NET should even be able to produce.The exception message is: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."The call stack is:
1. System.Windows.Forms.UnsafeNativeMethods.CallWindowProc(IntPtr wndProc, IntPtr hWnd, Int32 msg, IntPtr wParam, IntPtr lParam)
2. System.Windows.Forms.NativeWindow.DefWndProc(Message& m) [IL offset: 0x3e]

View 5 RepliesI made a program a month ago and i gave it to the customers.recently they report some bugs and i fixed them. when i send the new version installer to them, they have some problems running it.i used vs 2008 to write it, but i removed vs 2008 and installed vs 2010 last week. when i opened my project to start fixing program bugs it asked for convert wizard so i did it.i made changes and build it. i use installshield and i add framework 3.5 Sp1 as prerequisites.
note : i was using inno setup first time. so i changed the installer too.so i tried installing the program on my machine.i just noticed that i have only .net framework 4 installed my own system. so i have no idea how the program runs without any problems on my own system. i have even tried installing it on another machine who had framework 3.5. it it work on that too.the error shown on customers machines is related to framework version. everytime i send them a new version they have some problem installing/running it.
I have a class called FileInfo. It has properties for stuff like FileNumber, Vessel, OpenedDate etc.

I am using a Crystal Report in my application to display an Invoice. For this, I take the 'Invoice No' as input from the user. I was wondering if I could display multiple invoices on different pages of the report by taking 'From Invoice No' & 'To Invoice No' as input form the user.

View 7 RepliesI am using Microsoft VB 2010. I am to calculate the charges for a parking garage. I was to use to a method to do the calculations and output the parking charges. My problem is that everything displays except for the charge... What am I doing wrong? Here is my code:
[Code]...
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.
Public Class Form1

After several hours of searching the internet I could not find any Report Viewer tutorials that show a project that contains a parent/child report. I'm using rdlc report files.I can create a single report but we want to create a report that shows shows invoice header information followed by the invoice details followed by the next invoice header and details and so on.
If a sample project is not available, do you know of an online tutorial that shows how to do it?I saw something that might help on gotreportviewer.com about subreports, but it's in C# and not VB.Net so I could not figure out how it works.
So i have a program that is supposed to display charges for snowboard fees with and without boots. The charges are 20 for without and 30 with, and i have already declared them as constants. I have inputs for how many boards the user has.
My question is how do i create a summary to indicate the total number of snowboards w/ and w/o boots, total charges and average per customer.
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.
View 1 RepliesI'm trying to add charges to the account, specified from a textbox and change the results of the balance.It works to a point, that it adds a number (1) and then when it comes to adding another number. it kinda remembers the previous one in addition to the next one Im adding to it.I'm working with class instances too, so if there is a problem with that, please point it out.

View 5 RepliesThis question appears to have died, so I've decided to offer a bounty.What I'm most interested in knowing is if my scenario in the ETA1 below is viable and is used. If it isn't, then a good explanation of why not would be a good answer. Another good answer would be an alternative (but not including the internalsvisibleto attribute).
The best answer would be, yes, it's viable, everyone does it and customers love it!ETA2: I think I've thought of a good solution. I provide the customer with a distributable edition that is as functional as their edition but is unlicensed and has the classes and members hidden, using attributes.
I can do this with compiler directives, on every single important member, but I wondered if there was some global way to hide all members of a class?
A simplified scenario I have a class that extends a control in someway and I want to sell my class under two licenses;
(1) Standard - The customer gets x number of controls that use my class but can't instantiate the class (its internal).
(2) Developer - The same as Standard except they can create their own controls that use my class.
My problem is that when the developer customer comes to sell their controls, they can't help but expose my class to all their customers.
The only way around it, in my scrambled mind, would be for the developer to somehow integrate my assembly into theirs, and in that way I can keep the constructor internal. Or, use the internals visible to attribute.
ETA1: I'm thinking aloud here, but, I could have a list of permissable calling assembly names which the customer could add to. When they ship their product, their customers' assemblies would not be in the list and therefore they wouldn't be able to instantiate certain classes. (The list could obviously be hashed).
I am using crystal report for displaying reports. I want to display group by customers in report that i am displaying using group by funtion but i also want subtotal of that group by customers. I want to display received amt date, received amt and balance amout between given two dates.

But before displaying second customers list i want to display subtotal of received and balance amt. and in last in page footer i am displaying grand total of received and balance amt.
All data are displayed instead of subtotal of all customers. how to display subtotal of all customers received and balance amt?
In this program I am suppose to use data to compute a customers electric bill. My code works correctly for the most part except for two things. I cant get the loop correct I want it to ask the customer to enter readings but once it does it outputs the same information from the original time so I am wondering what I have to do to have it recalculate when new values are entered by the customer. My other issues is it is suppose to continue to ask the customer for additional readings till the value entered by the customer is -99999, when I run my program and enter -99999 it does not stop.

View 2 RepliesI have an application I am creating that displays pump information based on customers in a database. I am using VB2008 .NET3.5.I have a combobox that has a selection for a unit of measure. What I want to happen is when that is changes the labels that have a unit of measure change to reflect the change. There are 15 labels total that need to be changed and all there names are the only ones in the project that start with a X if that helps at all.

I need stop printing and paper feeding in the middle of printing in dot matrix printer.(Like a POS Printer - When wrote 'End Doc' on POS printer can stop paper feeding)
View 4 RepliesI am using VB 2008 & Access Databases for creating WinForm Applications. Also i am using Crystal Reports for Report solution. my question is How do i created reports such a way that they can be printed in faster Ascii Format on any DotMatrix printer. The default true type fonts make printing very slower.
I tried to use "Draft 10 cpi" font which come to available me after i installed a correct driver for my Epson printer. which also helped me overcome this problem. however it wont be the scenario with all my clients i.e. they might have different printers having different Make with different drivers installed. i have tried to open such project on there PC but the printing wont come in Draft instead the fonts get expanded too much & the print wont come right.
I basically have an application that generates reports in a .html file, I use a .html file for the ease of making tables and formatting text.Now I would like to introduce a way of printing the reports from my program. Because I use a .html file, the formatting would not the correct if I was to print it directly from my application (as far as I know). For this reason, I would like to print it just like my web browser would have in order to keep the tabular data intact and the text formatting.
