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))

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")

View 5 RepliesWhile I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.
I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.
I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:
' Copy Product/Categories
For Each oneProdCategory In OriginalProduct.Categories
Dim relatedCategory = _productContext.GetObjectByKey(New EntityKey ("ProductInfoEntities.Categories", "RecordId", oneProdCategory.RecordId))
