I'm a bit of a newbie and am trying to delete the current record on a form. next record, previous record is easy. i just write the following Me.CustomerBindingSource.MoveNext()
How come there is no "Delete" method available? such as:Me.CustomerBindingSource.Delete()
code available? I have my form binding to a database table called Customer and am wanting to write code for my own record navigator buttons.
How do I force users to save the current record (if current record has changed) and not let user go to the next record unless the save button is pressed?

I am returning to programming after a long absence (last real work done in VB5.0). I'm trying to do a small customer management project. I'm starting off with a DataGridView on one form showing a reduced number of fields. When the customer is selected a second form gives the full details. I struggling to find a clean way of passing the selected record to the second form. Both forms are using the same dataset.

View 2 RepliesVisual basic 2010. I am having a problem with updating on a DataGridView that has me confused.
I have a DataGridView on the first tab page that is displaying data in a DataTable.
On the second tab I am updating the current record on the DataGridView.
The text fields on the second tab are bound to the DataTable in the following manner
rnameTxt.DataBindings.Add(New Binding("Text", TableData, "rname", True))
When I move to the second tab the correct data appears in the text fields.
When I modify a field on the second tab the modified data appears in the DataGridView, on the first tab page. But when I check for changes in the DataTable in the following manner
Dim ModifiedRows As DataTable = TableData.GetChanges() I do not see the modified row - i.e. ModifiedRows = Nothing? Why is the modification not being identified???
How would I print the current record, ie the one that shows on the active form. App is VS 2005. DB is Sql 2005.

View 22 RepliesI have a ListBox populated with records and an insert button that activates an InputBox which prompts for the record name. What I would like is instead of an OK or Cancel button, I'd like a Insert Above, Insert Below, or Cancel button. My current workaround is using a second InputBox so after receiving the record name, this box asks to place it above or below. It would be much easier for the user having a single InputBox that takes the record number and having the three options, above, below or cancel.

View 8 RepliesI am a ASP Classic Programmer, professionally for a little over a year, I have developed some rather nice sites, including the one in my signature (Still a work in progress).
I have been forced to use ASP.NET (VB) for a FileUpload control, as it offers a self controlled way of creating Thumbnails, without the use of 3rd party controls, which is great, as my hosting server does not allow for 3rd party installs on their servers.
So.
The code below is what I have so far for connecting to the database and displaying a record is the "cookie" exist on the users computer.
Unfortunantly, this is not working, and to be honest with you, their is not a whole lot of resources available to show how to do this correctly.
So I am stuck with a lot of post and hoping that someone can actually assist me with this and tell me what I am doing wrong and maybe correct my code.
I am getting an error about the "Connection is closed"
If you want to re-write my code, I prefer something simple and basic, as the only thing that I am doing to checking rather the user is logged in, and if so, display a record from the database. I am NOT in the need for the DataGrid, so please do not suggest it, as I am only needing to check this one thing.
I would like to also add, that I have successfully contect to my database with the FileUpload control and save file names of the images uploaded, so I know that my connection string is done properly> But, for some reason the "SELECT" statement is causing a HUGE issue. (It was easier to insert, than to select, I am not use to that)

View 6 RepliesI have a database app where on a button click, I export the current record to crystal report which in turns converts it to a PDF file. Upon application startup, I export one record into PDF just fine but when I move ahead to the next record and I click the export button, the new PDF file that was exported is now blank. If I restart the app, I can then export the one record again but any subsequent record will export to PDF as a blank PDF file.
To sum up:I can export one record once using the below code snippet but when I try it for a second time on another record, I get a blank PDF file (only the crystal report formatting is in the PDF).
