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")

View 11 Repliesi 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))

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 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

View 5 RepliesI have a datagridview which I populate in data real time. I want to be able to scroll the DGV via code so that the user can actually see the row that is being populated. This is obviosly not an issue if the # of total rows are visible in the DGV. However, if the # rows are greater than that which is visible to the user, a scroll needs to occur. The next question is how much do you scroll the DGV.
