Reloading User Entered Data At First Run Logic

Aug 20, 2011

Ok so I have designed a program to figure out commissions for phone sales at my company. Since the devices we sell and their associated prices change over time, I had to make that data within my program dynamic. I have a form within my program (frmprice) that has 160 textboxes - 80 for the devices and 80 for the associated prices. Now I hard coded the .text members with default values for our current stock of phones and prices.

I also added code so whenever that form with the phones and prices (frmprice) closes it saves any changes that have been made to either the phones or prices and when the form loads it overwrites the default data with any data that the user had entered at last run.

HERE is my logic problem. At the very first run the program is overwriting the default hard coded values with "" because no user data has ever been entered before. So when the form with the prices loads, it passes the user entered data from last run which is null because it has never run before. If I test to see if default value <> the user entered data before it executes the code to pass the user entered values it will always test to be true because the user entered data is null at first run. If I test to see if the default value is = to the user data it will always at first run test to be false because there is no user data yet.

HOWEVER once the user entered data is initialized (anytime after the first run) I need the program to pass the user data from the previous runs back in. Just NOT at the first run. Here is the code i am using: (in the code below the variables ending in "val" are the ones that are of the type string and are saved in the application settings) The frmprice_Load Event:

Textbox Will Not Let User Leave Unless Data Is Entered

Jan 10, 2012

I've got a (hopefully) quick question. I've got textboxes attached to a binding source on one of my forms, and when I add, then clear, the data for the next entry to be added a small problem arises. If the user has previously entered something into, for example, Textbox3 and the user does not have the data for Textbox3 the user cannot move to the next field unless something is entered into the box.

Build And Display A Simple Diagram That Is Built From Data Entered By The User?

Aug 22, 2011

I wish to build and display a simple diagram that is built from data entered by the user. Because I can't post a picture of the types of diagrams here I'll use the following example. Image a picture of a house as a child might draw it a large square, with a triangle for a roof, a rectangle for a door, and two smaller squares for windows. Now I want to build an application that lets the user enter data and change that drawing according. For example, by entering the length and height of the house the size changes, change the number of windows, size of the door or height of the roof.

Now this may seem like a useless application but keep in mind the house is just an example the real purpose is different but should be as simply drawn. I'm looking for suggestions on make this work. Should I use a paint? or is something like this better done with a tie into the Visio references?

VS 2010 Allow The User To Merge Data From A Database Onto A Document And Print It?

May 5, 2011

I am trying to essentially allow the user to merge data from a database onto a document and print it. I am new to working with the PrintDocument, but I believe this would be the way to accomplish this. I know how to print the text onto the PrintDocument at a certain position, but what I am trying to figure out is how to deal with the coordinates of the text I am drawing on the PrintDocument. Ideally, I would love to click on the PrintDocument in a PrintPreviewControl and capture the coordinates of the PrintDocument.

Multi-user Application - Updating All Clients When A User Updates Data (push Vs Pull)?

Aug 26, 2009

I am designing a fairly small application to manage a waiting area for a clinical department. There will be a receptionist who books appointments and updates exisiting appointments to say that a patient has "Arrived". In seperate rooms will be nurses who call patients who have "Arrived" and update the appointment as "In Session" and finally as "Discharged". The appointments are viewed in a flexgrid with nurses across the top and time down the left, patient names are displayed at the relevant times and the cells are shaded a colour to represent the current appointment status ("Booked", "Arrived", "In Session" and "Discharged").

I am using SQL Server as the back-end and Visual Basic 6 (I know) as my front-end.I have been told that there will be 2 or 3 nurses plus the receptionist logged in to the system but I would like to cater for growth.My question is what is the best mechanism to use in order to reflect the status change made by one user on the screens of the other users currently logged in?

I have been thinking about using a timer to refresh the data at a set interval but I do not want to keep hitting the server excessively (although what is considered excessive? we would be talking about a call for data every 60 secs per user). Plus the server could be serving data for many other applications so this is another consideration.Alternatively I have been thinking about sending some kind of message via Winsock to the other users notifying them of data changes as they happen. I don't have a lot of experience with this and am concerned about clients not receiving messages and users seeing old data. It also seems strange to me that once the days appointments have been retrieved from the database that "in theory" a client could go the whole day without having to query the database again to pick up changes - kind of scary.Some information on the data:We would probably be looking at around 100 appointments per day We capture patient name, date of birth, date and time of appointment and appointment status.What is the standard approach / best practice for this kind of scenario?

Write Code That Will Control And Read Data From Applications?

Mar 22, 2010

I'm having difficulty figuring out how to run different programs with my VB program. Using Excel and other MS office programs is easy enough since I just add in the relevant COMs, but I can't for the life of me find out how to run other programs. I promise I spent many hours searching before bothering you kind folks here! I'd think this is a common issue so maybe I haven't been searching for the right thing.how to write code that will control and read data from applications.I know you can do "Process.Start" to open any application, and it looks like there are ways to determine the controls available on an open application, but I can't figure out how to do it. Is this possible? Or do I have to import a .dll file for every program I want to control? Or are both possible?

Write Some Code Which Parses Data And Then Populates A Listbox

Oct 24, 2009

I'm trying to write some code which parses data and then populates a listbox. I'm using the IPWorks IPPort component which basically does the reading of port 30003. The ipport1_OnDataIn event is where all the action is. I parse the data, which works great.. however when I try and do something simple such as add text to a listbox, I get the dreaded error "Cross-thread operation not valid: Control 'lstListBox1' accessed from a thread other than the thread it was created on".I've googled the error and tried copy and pasting some workarounds but nothing seems to fix the issue.

If anyone can offer help, it would be greatly appreciated. If you could possibly show the code already implemented into mine, it would be even better so I can see how it works. It would make more sense to me. My code is below. The part i'm trying to get working is the lstlistbox1.items.add("Test") in Case "2". This is to just get it working.. I'll be adding listbox items in the other cases as well, and they'll be parsed values instead of "Test". This is just to simplify things at the moment.

Application Displaying Sum Of All Integers Entered By User

Jun 21, 2010

I Create an application that when a user enters a positive integer value in a input box(the default number is 10) when the OK button is clicked, the application should display a message box with the sum of all the integers form 1 through the value entered by the user. If the user enters a negative value, the application should display an error message. I believe I have to use a loop condition but I have no idea what to do.

EX: User enters 10 in the input box once OK button is pressed a message box pops up and says "The sum of the numbers 1 through 10 is 55". Use the following test data to determine if the application is calculating properly
VALUE SUM
5 15
10 55
20 210
100 5050
