VS 2010 With A Button Amend And Delete?
Jul 18, 2011
I am having difficulty on the below code in understanding what is missing for the program to accomplish the below:Highlighted in red are the codes for Amend and Delete buttons:
1. The amend button was created to amend names, price and qty, with the code below it does amend the RentalRate(price) and intNoof Bike (Qty) however it does not change the Bike Name,
2. Delete Button code is as follows, when this is done i get an error "Index was outside the bounds of the array." at following bold red line
Private Sub lstBikeType_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstBikeType.SelectedIndexChanged

I'm trying to delete a number of records in a table from the last and forward. My idea is to use sql like this: delete top " & variable & " * from table where ID = something It gives me a general sytax error. Is it at all possible? Fuga. Edit: I also have the order by statement there. I just forgot to put it in the question.

i have been trying to work out how to modify a list box at run time ( i.e add in the detail when some presses a button ).I found some code in a sample program, which I thought I understood, but when a cut and pasted this code into my program, it didn't work as expected.The code which I cut and pasted was
Me.resultsView.Columns.Add("Match", CType(Me.resultsView.Width / 2, Integer))
Me.resultsView.Columns.Add("Position", CType(Me.resultsView.Width / 4, Integer))
Me.resultsView.Columns.Add("Length", CType(Me.resultsView.Width / 4, Integer))
[code]....
Obviously the top few line are meant to be column headers. Seem simple enough but they don't work in my program, I get no column headers.
When I run the program and pressed the command button, the only thing that appeared in the listview box was the word "This". When i pressed the command button again there was another instance of the word "This" appearing next to the original. The same thing happened the next time I pressed the command button.

Alright, simple as can be. I am stuck back doing my project again this year in college since i failed.So my question is if anyone can help me with the coding as to how i can restrict a member from the database, Also i wanna know if i am doing it right in terms of code for Amend.Try to explain it nice and simple.Sorry but unfortunately my college has blocked every single image host so i can't show ya all a screenshot but i can show ya the coding i have.
so far i have it laid out so user can input details of a member.I have 4 buttons on the form, one is Add, Amend, Delete and Cancel.I have the coding right for Add, Delete and Cancel.So i have a checkbox where if a member is restricted the change is placed on checkbox.

My.Computer.FileSystem.MoveFile to move logs of a command line application to the directory that I want.The problem I'm having is that, if the file already exists, the program errors out. Which makes since.I could just use conditional logic to replace or rename the file if it exists. The problem with the former is that I need to keep all of the logs and the problem with the latter is that, without knowing how many files could exist, I wouldn't know when to stop renaming files.If I knew that there were only going to be 5 files, then I could work with it. But since there probably won't be a finite amount of files, I need something automatically amend the new log to another name. For example, if I had "Test", then the log would amend the next file Test1 and so on.

I am trying to create a sign in program for my members. They come to the computer, input their birthday (already in the database), and up pops a Form with DataGrid that shows all the members with that birthday. Here is where im getting stuck. I want the user to select their name (row) from the DataGrid, click the button Sign In, and have the database be updated in the "Attendances" column to previous+1.
I first approached using the DataGrid1.SelectedRows.CopyTo method but had no luck. If someone could please help me to read which row the user selected, and then search the database for that persons name (which the row contains), and add 1 to a column in the database.
'Begin Code
DataGrid1.DataSource = Nothing
DataGrid1.Columns.Add("first", "First Name")

I have ModalPopupExtenders that show associations that are NOT tied to a specific product. The associations that ARE tied to the product are shown in a tabcontainer with delete imagebuttons next to them. When I was testing earlier I noticed that the associations that I delete from the tabcontainer don't show up in the modal unless I click on the refresh button in my browser. Is there some code I could use that would make it so that when I click on the delete button, it will automatically refresh my Modal so that I won't have that extra step? [code]

I'm trying to code the delete button in my binding navigator and I keep running into errors. This is what I have:Dim msg As String = "Are you sure you want to delete the current record? " If MessageBox.Show(msg, "Confirm Delete", _ MessageBoxButtons.YesNo) = DialogResult.Yes Then _CustomersBindingSource.Remove(DataGridView1.CurrentRow)
End If
Me.TableAdapterManager.UpdateAll(Me.DatabaseDataSet1)
Even when I change it to _CustomersBindingSource.CancelEdit and I debug it, the Delete button in the binding navigator looks like it set to enabled = false, but in the properites it's set to true.Even if I add enabled = true at the top

I have a main form (Form 1) with a menu strip and navigation bar. I use the main form to launch other forms (Form 2) as children of the main form.
All of the children forms contain SQL data sets /grids. I would like (if possible) to use the save button on the main form, to save data changes of the children form to the SQL database.

well, i am working on a project using tables by simply dragging and dropping them on a form.
from a single data set, i dragged 9 tables into 9 forms.. the fill method of tableadapter works whenever the form loads
now my problem here is, there's a problem with my binding navigator that the save and delete buttons aren't working..
this is actually my alternative method. since this morning.. i couldn't make my binding navigator work for my tables (i was surprised to see that there's only one working binding navigator from a single dataset, and because of that, i thought i could just use it to work for my 9 tables instead). still it doesn't work.. and i thought of using different forms for different tables so i could get the binding navigators work perfectly..
and yet, it doesn't make any change at all. still there is problems
is there any way to make this work?
how about adding codes into the delete button event in the binding navigator?

I have a block of code below that allows the user to create new buttons at runtime at the click of the right button at runtime.But i am wondering how to detect the selected button on the main form and then the user can delete the selected button at runtime.
The other thing the user can do is also to drag the button around the win form when in runtime. Cause i'm new in VB and i am exploring this part. the code that i have is here and it is created by one of the member in msdn.
