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.

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..
I 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.
Is it possible to have a single class reside within two name-spaces and how can I do this?
To clarify: We have a class library (let say root namespace is classLib1), which has grown over time (more classes) and I want to logically group classes into different namespaces. However some of the older classes need to be grouped into these new namespaces (e.g classLib1.section1) and doing so will break legacy code in other assemblys that use this class library. So I want to be able to refer to a class using both name-spaces until we can phase the old ones out.
I can't find any information on this, which suggests there is a reason that people would not want to do this!?!
I have a VB.NET solution (call it S1) which produces a .vb file (say File1.vb) to be compiled and then included in another solution (S2). S2 is a console app which I want to run from a cmd prompt, not VS. My plan is to shell out from S1 to run a batch file to do the compile and then copy the .dll file, overwriting the old one in S2 (then I can run S2 in a separate operation). Here's the batch file for the compile:
I'm doing a project for my beginners programming,logic, and design class. The project is a Sales Solution/Bonus Calculator. I really just want to know if I actually coded the array correctly. I've found the same project on here but I wasn't even really sure if what they had up was correct. I have a pretty solid idea of how to get through this I'm just feeling a bit overwhelmed. If you notice any other errors please point them out. I'm not looking for the answer I'm just looking for the path to get there on my own merit. Here's what I have so far:
Public Class Form1 Private Sub Report_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CreateReport.Click
So websites can tell what browser you are using: [URL]. How do I fool it to think I am using a different one? For my project Iam using the web browser component but using something else is fine. And also how to fool what os I am using? Another point is I want to make these variables that I can change them. How to use VPN or an other program, I want to make it in vb.net!
I have Single VB Class inside website project and I need to generate XML Documentation for this class. is there any tool that can generate this documentation?
I have a USB gadget that appears to Windows as a USB serial port, there is no special driver.I know the USB Vendor ID, and the USB Product ID, I need 1 or 2 functions:
I am trying to write a program where a user logs on to the system and then enters predictions for the world cup matches. I have created the login screen which searches the 'users' database for the inputted username and password - it works (kind of) in the fact that users are granted or denied access. After a successful login, however, the system seems to forget who's logged in, therefore any predictions entered cannot be related the the userID of the 'users' table.
Here's the code I have in the 'login' button of the login screen: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim connection As New SqlClient.SqlConnection Dim command As New SqlClient.SqlCommand Dim adaptor As New SqlClient.SqlDataAdapter [Code] .....
My question is whether Text Classification, Categorization and identification is one and same thing or there is difference between them, if it is not the same so what is the difference. and is it possible to make a such a program in Visual Basic? that identify text i think it is type of machine learning? am i right?
In a number of my projects, I find myself declaring a rather boring class:
[Code]...
to e.g. allow an object to give information to another object in such a way that the information can be mutated later wherever it goes. For example, in a Dictionary(Of String, Holder(Of SomeImmutableType)) it's possible to update the thing of SomeImmutableType without having to change the Dictionary itself (since the Dictionary's entry for a given key will always contain the same Holder object, that Holder object may be used as a lock).
I'm trying to identify if the input of a textbox is non numerical, which cannot be converted to an integer/double for calculation. I do this by converting the input1.text to ascii, and looking at the value to determine the type of input. My question is whether there is any way I can analyze the whole input character by character? Asc() only gives the ascii value of the first character, but what if the input is "9W" etc? Such inputs will pass my character test, but cannot be converted to an integer.
The "named pipe" seems rediculous to pass data between processes (exe's). Is it possible to run a single instance of a VB.NET Class Libary (dll) such that two programs can access the same memory resident dll, thereby passing data via functions and or subs?When I try to make the class library as single instance, the "Enable Application Framework" is greyed out, and thus the option to "Make Application Single Instance" is also greyed out.When I try to call the dll from two processes, I simply just create two instances, so storing data in a module doesn't work
I'm having a problem with a class issue in VB 2005. The error message reads "The class Tellerform can be designed, but is not the first class in the file. Visual Studio requires that you use the first class in the file. Move the class code so that it is the first class in the file and try reloading the designer again."
Dim find_id = From p In dbContext.Residents _ Where p.person_name = occupant _ Select p
I then pull the first returned ID like so:
Dim building_id As String = find_building_id.FirstOrDefault.id
This works fine, except with the person has a ' in their last name, like M'arta. In this case I get a NullReferenceException.
Okay, the problem appears to be that when I am capturing the name initially from a GridView it is inserting into the value a #39 instead of ' and then LINQ is keeping things correct, so I end up with a non-match since it is attempting to match:
I have a vector class...and the magnitude is single precision...Now the problem is this, when I run this with option strict on, it gives me the going from double to a single error...Why? Does multiplication imply double precision?
So with option strict on, can you not multiply single precision numbers together and assign them to another single precision variable without first convert.tosingle?
What is the point of this? I am currently changing hundreds of lines of code in a project that runs perfectly...
How can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:
Public Class MyInterface Public Economic as EconomicClass Public Sub New() MyBase.New()
[code].....
So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:
This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.
The error it has is that when one of the text boxes is changed the code changes all of them triggering every single function to activate. Is there a simpler solution other then recoding it from the start? also each different Private Sub is identical basically.
Public Class Form1 Private Sub K_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles K.TextChanged Dim T As Double[code]...
I know the code is very brute forced & sloppy but its the only way i really know how to do it.
