DataGridView Saving - Set Employee ID In The Related Table In The Grid to The Value From The Employee Record?
Sep 15, 2009I 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.

PayRoll Calculator On Vb - Program That Accepts Input Of Employee Name, Employee Type, And Number Of Hours Worked
Sep 30, 2009You 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 want the list to be showing all results and then the details secion giving only information on the selected employee. Do I need two dataset for this?

Why Can't A Government Employee Be A Microsoft Community Contributor
Jul 14, 2011On Tuesday, 28th June 2011, I received an email from Nestor Portillo, Director Community and Online Support, Microsoft informing me that I have been awarded the Microsoft Community Contributor (MCC) Award for 2011. It was a cheering news for me in more ways than one. I am a Chartered Accountant (or CPA) with no formal training in IT. I am a government employee in Nigeria where most people are barely IT literate. I am into programming out of personnal interest and because I see a great potential for future benefits in that field.
But my joy was cut short because as I followed the steps towards printing my Certificate and redeeming my token, I was informed that government employees are not eligible for MCC award! For once, I regretted the honesty of admitting that I'm a government employee in the radiobutton provided for that. I find it too hard to understand why I am being denied this award just because I'm a government employee. If being a government employee does not disqualify one from participating in this forum, why should it disqualify one from benefitting from the token recognition of being here and sharing ideas and knowledge with others? Shouldn't Microsoft be encouraging government employees to take part in this forum knowing that public servants are the least interested in IT? For those of us in Africa, shouldn't my recognition serve as an incentive for others in government to show interest in IT? Or is Microsoft not interested in IT education and development of government employees especially in Africa?
I forwarded a protest letter to Portillo on the 30th of June 2011 but have not received any reply two weeks later. I am using this medium to appeal to Microsoft to kindly reconsider the exclussion of government employees from its awards. I am not in any way involed with any activity that may create conflict of interest if that is the issue. I am also appealling to other forum members to join this debate with a view to reversing this patently discriminatory and obnoxious rule.

Write An Application That Evaluates Weekly Pay For An Employee
Oct 28, 2011I needed to make an application that calculates weekly pay of employees at an hourly rate. The overtime schema is that: hours less than or equal to cutoff1 are paid regular rate. hours over cutoff1 but not exceeding cutoff2 are paid 1.5 times regular rate. hours over cutoff2 are paid double time or 2 times regular rate. [Code] The employee must choose Category A, B or C depending on the amount they have worked. I am completly new to visual basic, I am not sure how to continue with my if and then statements. I must also create the application with 3 radio buttons, where the user clicks either Category a b or c and then buttons which say calculate and clear. [Code]

Load Up A Text File Which Has Employee Info Separated With Commas?
Apr 13, 2009I'm new to Comma Delimited values. What I'm trying to do is load up a text file which has employee info separated with commas
like 1/1/09, John Smith, (555) 555-5555, 101 S 1st Street and has numerous rows of info like this
so what I want it to do is just write this info to 4 different textboxes
like txtdate would just have all the dates of employees listed in rows or multilines
then another text box for names and so on.. Right now I just have it all being written to one text box.
I'm not sure how to separate all the information accordingly.

Class Collection Property - Method - Allow For An Employee To Be Assigned More Than One Work Location
Jun 17, 2011I am experimenting with a transition from my application built in VB6 to vb.net. I know, about time. At the same time, i am making changes and improving upon the original. One area that I am working on is within my employee class. very standard class, nothing fancy. One change I want to make though is allow for an employee to be assigned more than one work location. Employee has (is assigned) Stores. In reading about collections, it appears they are different in .net (as they should be), but I don't know what the sytax changes will be to implement my changes.
View 6 RepliesCreating A 'smartform' - Click On A Search Feature In The Top Cell And Input An Employee ID #
May 17, 2010I 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.
Using A Collection : Store 3 Pieces Of Information For Each Employee In The Company On A Daily Basis?
Feb 27, 2006I am trying to come up with a way to store 3 pieces of information for each employee in the company on a daily basis. So for instance

Day 2: Sam, 10, 90
Day 3: Bill, 5, 40
Day 4: Bob, 8, 40
Day 5: Sue, 2, 50
most of the applications that I build are Create, Read, Update and Delete type applications that don't really need arrays so I have almost no experience with either.
