I am trying to add a player registration form to a textfile. And i have a few problems.One of these is that when adding to the textfile, it isnt recognising the selected value in a checkbox (checkbox is used to distinguish between a goalkeeper and an outfield player). Can you tell me what should I be writing to make this happen, - "chkGoalkeeper.??? = "" "

View 3 RepliesHow would you store records in a textfile to an array, so you could display it on a series of textbox(ie. firstname, lastname employee number etc.)

I know that when I add a record to a table through a binding source using a binding navigator - it completely handles the IDENTITY PK (it's bound to a textbox and you can see it immediately).
Now I'm trying to do this differently in another part of the program - here I only have a BINDING SOURCE - that's bound to a DATAGRIDVIEW.
I put a new record into the DGV like this
Private Sub vendorfilesDGV_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles vendorfilesDGV.DragDrop
If e.Data.GetDataPresent(DataFormats.FileDrop) Then

I have a project that is used as management for a YouthFootball Team. Part of this is adding training fees and keeping track of who has, and has not paid.This part of the project is adding the fees to the relevant textfile.Textfile - Trainingfees.txt
Each line looks like - player name|number of sessions attended|amount paid I have a form with a DataGridView. Each row is populated with: Checkbox Column, Player name in textbox column, blank textbox coloumn The user then ticks who attended the training and how much money they paid in that session.
I then have this code to loop through the DataGridview and add call a separate function that adds the relevant information to textfiles.

I can retreive all items in my notepad but when I am adding them up in my listbox, and trying to print them in the console. I can only display two strings. I don't know why. My string is a combination of a name, space & score. ex: "luke 300". That is the pattern of all strings per line in my text file. I am separating the name and the score using space as the indicator. When ever a space is found, string before and after the space is retrieved and added to the listbox
Here is my

I have been trying for a month to get a row added to an Access database and can not do it. I have the databindings all set and can select different records, but can not add a new one. I have tried BindingSource.AddNew.row() but can't figure out how to add data to the new row, nor does it show in the database.
I have tried
Dim ds As New myDataSet '<---Change this to the dataset name on your form
Dim dr As DataRow
dr = ds.Tables("Students").NewRow
[Code].....
But that doesn't do anything at all. No data added, no errors. I have tried updating a datagrid to be told it can't be updated when bound. I look on google and nothing seems to relate to adding data to an access database when bound to the project through the datasource wizard.
having trouble adding records to an existing dataset, I tried the following code but it made a new connection which I don't want:
Dim inc As Integer
Dim con As New OleDb.OleDbConnection
Dim da As OleDb.OleDbDataAdapter
Dim sql As String
[code].....
I have the following code which I hoped added a row to my DataGridView and also a record to my database. It does the first part, but not the second.
Dim row As DataRow = Me.CCLogDataSet.tblLog.NewRow()
row("cc_log_contract") = Me.txt_Log_Add_Contract.Text
row("cc_log_registration") = Me.mtb_Log_Add_Registration.Text.ToUpper()
row("cc_log_milage") = Me.txt_Log_Add_Milage.Text
[Code] .....
It seems to be storing the data in memory? As the data in the DataGridView is persistant, even after a Relaunch of the application. However, why I query the database, there are no records in it.
I'm trying to add a record through access. Below is my code. My problem is that when I add a new record, it adds to the database fine, and goes back to the first record like it should, but when I then scroll through using the BtnNext (button), it replaces the last record with the first record for some reason. This is the UI of it [URL]. A bit of further explanation, I'll have 3 records, IDs 1,2,3 respectively. I go to add another (with its ID as 4). When it's added, the program displays ID 1 as it should. It then goes 2 then 3, but instead of 4 as the next one, it displays 1 again. So 1231.

View 1 RepliesProcessing an XML file with LINQ to add records into a table in a SQL Server database via a data context. As we are adding records we need to assign the parents in various other tables.

I was asked to create a program that inserts records into one parent table and multiple child tables. My question is, how do I know what the PK is for the parent table, so that I may add it as a FK in the child? The PK for the parent is an auto number.

I have records in my datagridview (from database(ms sql server 2008 r2)). What i want to do is to insert the records selected by my datagridview checkboxcolumn and IF POSSIBLE automatically delete a record if the records to be inserted are equal to the records inside the database. (Hoping you got what I want to say.) For example. I have an A,B,C(child) that is under XXX(parent) in my database and I'll be inserting the A,B(child) again but it will be under YYY(parent). The old record in XXX will be deleted except C. I just want a possible DELETE STATEMENT These are what I've done so Far :

View 3 RepliesI'm, using a SQL Server table in a DataGridView and I'm having trouble adding records. I'm new to vb.net but used vb6 for a lot of years so the transition is a little difficult.
