User To Be Able To Add/remove An Employee Record And Update The Input File Before The Program Is Closed?
Apr 25, 2011
I'm trying to create a program, that upon opening, will read an input file containing a delimited employee record. The record will contain the name of the employee, their salary and the number of years they have been employed.I'm looking to display only the name of the employees in sorted order(alphabetically) and then when the user of the program selects a particular employee, I want to display the salary and number of years for that employee.I would like the user to be able to edit the recors for the employee and I would also like to have a way for the user to be able to add/remove an employee record and update the input file before the program is closed.

You need to design and create a program that accepts input of employee name, employee type, and the number of hours worked each week for two weeks.
You must be able to select an employee type. An employee of type Trainee makes $10 per hour. An employee of type Regular makes $15 per hour. An employee of type Manager makes $20 per hour.
The program should calculate the employee pay for the week. The employee should receive 1 times the regular pay for any hours worked over the prescribed 40 hours in a week. The program should output the following information:
-The employees name without trailing or leading spaces
-Regular hours worked
-Regular pay
-Overtime hours worked
-Overtime pay
-Total pay
The Problem that i am having right now is "Displaying " the overtime hours on my "FORM VIEW" i mean i did the math right its just when i type (lblOverHrs.Text = CDec(CDec(OvrHrsWrkWeek1.Text) + CDec(txtOvrHrsWrkWeek2.Text))
Its says the "OvrHrsWrkWeek1 and 2" are not Declared which are..im not really sure where i went wrong..
Heres my code

I have a VB project with a form where user adds/modifies the data, data are stored in SQL. On the form there are 2 tables that are linked by employee ID. When I test the process and insert a new employee record and add new comment for this new employee in DataGridView - when I save it I get an error that "Object reference is not set to an instance of an object". During more detailed debug it says that CurrentCell is set to Nothing - even that I do have values in all fields.I do set employee ID in the related table in the Grid to the value from the employee record - so all primary keys do have value and the comment is saved after all but I get an error and saved comment dissapears from the screen right after saving. When I pull the same new record again - everything is saved. What am I missing and how to avoid the error and dissapearing of the saved comment?
Also - I tried to save the new employee data in the first table first and then add comments - it didn't solve the problem. But if I add first part of information in the main table, save and close the form, then go back and add comment - it works fine. The problem is - it's not convenient for the user - they'd like to enter everything at once.
Private Sub TblCommentsBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TblCommentsBindingNavigatorSaveItem.Click

I am handling many of the BindingNavigator tasks (MoveFirst, MoveNext, etc.)in code to ensure that I always ask the User to save his changes.
The one area I am have a problem is PositionItem. I would like to sense that the User has changed the Record Number in the BindingNavigatorPositionItem, handle my record Update, and move to the Record Number the User entered I have looked all over and have not found any way to do this.

i've added new item called service- based database. after that, i've created doctor table, course table, exam table, and an empty table called exam_report to allow program selects randomly from the other tables.
how it works: first the user will get a form with many buttons: courses, doctors, exams, and exam report. second if the user click over exam report, a new form will appear with many columns. this form should has exam course - exam day - exam time - 3 doctors name who will observe the students.
behind code: the doctors shouldn't be the instructors of the course - the doctor has no appoinment in this day - the doctor has no hloiday and so on..
okay my code is the following :
Public Class Form6
Dim j, a As Integer
Dim d, f, h As Integer

It's been a good few years since I dabbled in VB and I'm very very rusty so any help would be great! What I'm looking to do is search an access database with user input and display the relevant record.I have a single table set up in an access database called school_info with the following fields and data:
Tres________DfE________Name_________Type
001________1234________School 1________Primary
002________4321________School 2________Secondary
[code]...
I've linked the database to my new project, connected the database and added the 4 fields to my form. When I run it, the data shows in the boxes fine.The Tres and DfE fields are show in text boxes on the VB form, and the school and Type are show in labels. What I really want to do is be able to manually type in either a Tres or DfE number into the relevant text field and have the other labels auto populate with the relevant data that's stored in the database table.

im currently designing a system that enables the user to input a customer record. the customer record is broken down into 11 fields: customer id, title, forename, surname, house no, town, city, county, postal code, contact number, date of registration. Problems - i need to be able to insert the new record into a file and for them to be organized into surname order (for a binary search to work) at this moment it will only sort by first field (which is unnecessary as the customer id number is generated automatically and is all ready created in order). Also, im having trouble with sorting the array that contains all the variables from the text file.

I am trying to create a function to remove dirty words from user input text and want to replace those dirty words with four ****. In my scenario , i have list of dirty words where i would iterate the input user text and want to replace. Say for example.,
Dim InputTxt As String = "hi bush how are you.... $hit and @ss"
Dim OutPut As String = " hi **** how are you... **** and ****";
Problem: It works fine to replace some word like " bush" however fails in the below function doesn't replace "$hit" and "@ss".
Note: I do not want to use string.Replace because it doesn't have word boundary in the sentence..
Public Function pReplaceWords(ByVal dirtyWord As String, ByVal inputText As String, ByVal options As RegexOptions) As String

On my website I have user records. For the user records page I have three options you can do with each user record. Delete, Update and Email are my checkboxs's that I am trying to use.
<Input Type=CheckBox Name=Delete OnClick="False" Value=<=rs("num")%>><br>
<Input Type=CheckBox Name=Update OnClick="False" Value=<%=rs("num")%>><br>
<Input Type=CheckBox Name=Email OnClick="False" Value=<%=rs("num")%>>
What I want to be able to do with these check box's is when one of these slections are made, I want to be able to pass the value of the selected checkbox by pressing a button over to another page where I have a IF statement. Then value of the selected checkbox runs though the IF statement and matchs with the option in the IF statement.
[Code]...
So I guess what I am looking for is how do I get the value of the checkbox to pass over to another page and run through my IF to match with an option in my IF statement.

I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

I created 2 forms in Access 2003 (Form1 & Form2) for the purpose of creating a 'smartform' of sorts for my company. In essence they can click on a search feature in the top cell and input an employee ID # which automatically fills in about 10 to 15 fields.
- There is only 1 table attached to the forms.
- The group I created this for is uncomfortable using Access.
What I would like to do with VB.net:
- I thought I would create an internal webpage using VB.net so they wouldn't need to log into Access [the DB would be stored on a separate server.]
- I would need a clean & simple interface that has 2 buttons, one for each form.
-When the form is called up I would need a search feature "EMPLID _________" which would connect to the Access DB table and retrieve the correct information.
-Id also need to have the form printable & have the ability to search again or return to the front page.

I am new to VB.Net and programming all together. I am trying to make a program that will take 2 numbers input by the user, Add them together and display the sum. Then take the sum and divide it individually by each number to give you what percent of the sum the numbers are. I'm working on making it a program that will calculate the Hardy-Weinberg equilibrium for my Anthro Class. I'm just doing this for practice for my VB.Net Class. But i will move onto that at a later time. I just want to finish this first.
So.. Here is my code so far. It's not complete yet but this is should be enough to make it function.

I am trying to write a program that allows user input information and plot a bifurcation diagram that looks like this:I haven't program in 2 years:sick: so I am all rusty and such. Here is what I have got so far and more information about what I am doing.
Bifurcation:
f(x) = kx(1-x)
and k = xL + i * (xR-xL) / 500
when i runs from 0 to 500, it plots (i, f(seed)), (i, f(f(seed)), .... up to the boundary number.Here is what I have got so far. Everything seems normal, however, I am really confused when it comes to plotting.

i want to make a program in which the user can input a mathematical function so the program can then work with it. So the user would input something like x^4+x+2 and then an x and the program would calculate f(x). What i don't know is how to let the user input the function.

I have a program written in VB 2010 express under windows xp which does some heavy number crunching combined with serial communication. When it "gets too busy" it does not update the screen anymore (done simply with Textbox.text = "any text") and it does not respond to user input in any text box. Not even to a click on any text box. Is there a way I can get the program to do screen update and respond to user input while it is busy?

which works fine but if i exit the program by the x mark in the top right corner it closes the app but the apps name is still in task manager and if i re run it there is 2 instances of my app running so basically it closes the app but it leaves in in the memory i believe can anyone explain why this is happening and a solution because it makes no sense to me because that it part of windows itself not my programming so i don't understand it at all.

how do I handle the errors that may appear from the user of my program. For example, I have an triangle area program in wich I ask the user of the program to insert the length of the base and height of the triangle in a textbox. But what if he inserts a letter or something else, like a sign....my program will crash...
I know that one method would be to use On Error GoTo but I don't know how. If maybe you can direct me to some link or you could explain how do I handle errors, I would be grateful. Maybe you can even show me other ways to avoid errors from the user input.
This is my small program so far:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
Handles Button1.Click
Dim , Height, ARIA As Integer
