I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()

Since some of my users log on as non-administrators, (without administrator priveleges), where would you reccomend I store their programs data files. For example, the program Test Prog would store user data in: [code]The problems is permissions file access when they are not signed on as the administrator and they need read write access to their data files. Also is there a universal system directory name I could use so it would be the same on all users computers, like %Documents% or something?
View 2 RepliesI would like to develop a program to create a report after reviewing a facility's processes (Quality Issues). The reports are to be created using Microsoft Word 2010.
I'm OK with developing the forms and controls to access the form and the user inputs.
What I need guidance on is the best way to save the input information from the user forms (over 100 total) as it relates to that facility, and to retrieve the info in case clarification is needed. Also, each user may have several facilities to review.
I want to store some information of the form in such a way that if the user quit/exit the application it stores the information. When user runs the application next time the information should be available to him. It also involve the restart of the computer. The application is in vb.net 3.5 framework. The one way that i can think of using flat files and encrypted data, but i can not do this. I do not to store any kind of data on client side and I can not store this information on server side. The problem is of getting client machine information and storing it on server.

The company require an application that displays coffee usage information for the managers of CostaB Coffee. Sample data has been provided for last years (2011) monthly usage amounts in kilos and is as follows: 400.5, 450, 475.5, 336.5, 457, 325, 220.5, 276, 300, 320.5, 400.5 and 415.

Utilise appropriate formatting for input/output and include appropriate error trapping and data validation in the application.

View 4 RepliesI am trying to store confidential encrypted user information for my program on a single computer. I do not want the application to be copied on to another computer and be usable. So I was thinking about storing the information in the Registry but I read that that is a very unsafe location and is bad for more reasons then one. I started storing the information in the programs Settings.config file but I am not sure how to encrypt that information. The only thing I have gotten to work so far is storing the information in a XML file and encrypting that which has worked but I want the information to be more hidden and more secured.
View 9 RepliesIn the past I've used a Singleton Pattern to load the connection string when the application starts via the global.asa file.
I have a project now where each user has a unique connection string to the database. I would like to load this connection string once. The issue is that the singleton pattern will not work for me since each user has there own connection string. Basically the connection string is created dynamically.

I have an application that uses Dataset.WriteXML to create a small backup before data is syncronized to a data store (less than a meg).This application has worked well for 5 years now, and all of a sudden with the installation of XML 6.0 SP2 the XML document is not working correctly.I have multiple tables within a Dataset (Company, Contact, Notes, etc...)When WriteXML is called, the first table should be Company, however, the first table is being named Contact with the Company Data in it. The Notes table is being called Contact and so forth. In other words it's not giving the correct names to the tables in the XML File.This appears to be a bug, which is causing great distress on all the companies who have been using this program.

I need to have the ability to have a Global variable/class that stores some basic information about the currently logged in user including that user's preferences, security rights, UserID, etc. This information will be needed by any/every part of my application. In the past I have either used a Public variable/class in a vb.net module for this purpose. I'm trying to get away from my old ways of doing things and was curious what people currently do for this functionality.
I am thinking a singleton or 2 regarding preferences and security but am not sure if that is the best way to go.

I am creating a windows application using visual studio. I want somehow to insert an excel file into the application so the user will be able to download it from the program and save it to his computer. This means that the file will be a part of the program. There will be a button that will prompt the user to save the particular file somewhere so he can then view it.
What should I do in order to "embody" the excel file to the application? And what code should I write to link the file with the button?
