View 15 RepliesI have a form with multiple tabs that allows the user to insert data into a customer table.The ID is an Identity column. After a row is inserted into the database I would like to retrieve the ID number for that row that was just inserted into the database. Can you tell me the best way to do this?When the user clicks on a Relatives tab the application inserts the customer to the database. If I can get the the newly inserted customer ID then I can use it for the CustomerID column of the Relatives table when inserting a Relative so the 2 tables are properly related. At present the program uses this code to do just that but this code will only be good for a single user system. It's possible that we may sell it as a multi-user system and I think the current way we are doing this will fail because there is not telling whose ID will be returned in that scenario.
Here's the query that we are using:
SqlStatement =
"SELECT Max(ID) " & _

I want to get last inserted @@identity in table on FormView1_ItemInserted
Protected Sub FormView1_ItemInserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewInsertedEventArgs) Handles FormView1.ItemInserted
End Sub My issue is that I want to redirect my FormView to readonly mode after FormView1_ItemInserted but for that I need to show the inserted record in readonly mode and that is only possible if I get my last inserted @@identity.

I currently have a JSTree all set up to do the creation and renaming of a new node:[code]The problem is that my success doesn't seem to get hit when I return an integer ID on the create node, thus I can't set it to a global variable. What exactly do I need to return in the function to get back the ID from the server? I'm simply returning a new integer right now.

Im curently writing an app for windows mobile (so its using the compact .net framework)It has a loop which finds out how many images are in a folder, makes a picturebox for each one, then sets the .image property to the appropriate image. It also adds the name, size, location etc.What I dont know how to do is add a mouseclick event to it?I probably would have a subroutine already written in the code which could be used, or would it have to be a new one made for each picturebox?

But thats not very professioanl in case the user wants the full picture information?

View 2 RepliesI'm trying to build a new customer data entry page for a db project. One of the features I would like to add is a way to check and see if there have been any new records that have been added that haven't been explicitly saved to the db. If so, when the form_closing events fires I want to evaluate whether or not new entries have been made that weren't saved, and then count the number of rows that haven't been saved.

How to make my program not to use the newly created file 'text.txt'? Notepad fails to open it, it says (The process cannot access the file because it is being used by another process).
I have a Private Sub that I execute whenever a user clicks one of two or three things, and in it I create a new tab in my TabControl. Once the new tab has been created, I select it then add a formatted textbox to it. However, it is not selecting the new tab and therefore only adding the rich text box into the already selected tab (not displayed, of course, because it has a dock style of Fill.) Here iis my code to select the new tab and format / edit the rich text box:
Try
tabMain.SelectedTab = tabMain.TabPages.Item(intTabIndex) 'Select the new tab
AddHandler rtbCode.TextChanged, AddressOf DisplayUpdate 'Add TextChanged event to handle updates

I've read about @@Identity. I've also read that it's no longer supported. I get lost in the mountains of data searching provides.I'd like to get the "ID" field, which is an AutoNumber Primary Key field, when I insert a new record. There's got to be a simple way.
View 1 RepliesI have encountered a wierd problem, and I'm unsure if this behaviour is caused by my code or by Windows itself... I can't make any sense of it! Basically, I have written an automated backup system for a text editor. It should save up to 5 backups for each filename, each in a 'AutoBackup<filename><filename>_<number>.bak' format. Here, <filename> is simply the name of the file my program is backing up, and <number> is the first 'free' number. So if the backups are "Test_1, Test_2, Test_4, Test_5", the next backup will be called "Test_3" (since 3 was 'missing'). When there are more than 5 backups, I want my code to delete the oldest files until there are again 5 backups left. I am using the following code for this:
vb.net
'Backup doc.SaveFile(path & "" & filename & "_" & newNum & ".bak") 'If more than max files, delete oldest Do While numOfFiles > maxBackups Dim d As Date Dim maxDate As Date = Date.MaxValue Dim oldestFile As String =
[code].....
Then, after another backup, Test_1.bak is again deleted!I thought this was pretty weird so I had a look at the files in windows explorer, taking a good notice of the creation date... That's when I saw that after Test_1.bak is created a second time (after a file named Test_1.bak was deleted), it carries the same creation date/time as the old (deleted) Test_1.bak..So my code still sees it as the oldest file (while it is actually the newest) and deletes it...
I wrote a program that writes to a new created file a line of text. Anytime I try to open the new created file, I see a dialog box titled "Inconsistent Line Ending". I do understand why I receive this message. I wrote this program in VB.NET.
View 1 RepliesI've created a database in Access 2007 and connected it to Visual Basic 2008. My database have tables Coachee and Coach. Details of Coachee are displayed in one form and there's a button that when clicked will show details of the Coach of that particular Coachee in a another form. If the Coach is not in database, user will be prompt to insert a new Coach record. Problem is, when saved, the newly inserted record will not be displayed and i have to exit and rerun the program, only then the record will be displayed.
