I got 100+ textboxes that display record values. Most of the textboxes display correct values but several textboxes doesn't. These are the same textboxes. And they only display wrong values if I edit a record for the first time. After correcting the wrong values in the textboxes the first time, they display correct values in succeeding editing of records. Tried to compare their properties and all but they are the same with textboxes that worked...

I've been struggling with this for hours. I'm making a vb program to track volunteer hours. I have some fields that a user can fill in and then click update and it should add the volunteer info to the database. To confirm that it was added I'm using a datagridview that can be updated to show the volunteers in the database. My success msg says that the insert worked, and the information is showing up in the datagridview but when I close the application and go to 'show table data' for the volunteers table there is nothing there. I've tried adding .Update() to my VolunteersTableAdaptor and I've tried resetting my SqlCeCommand after the ExecuteNonQuery() call, but these haven't worked. When I hover over the last word 'Volunteers' in this code:
Me.VolunteersTableAdapter.Update(Me.AddVolunteers.Volunteers)

CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)

In an attempt to learn VB I'm trying to build a database project for a friend's business. This db will be used to track customer information, predominantly for targeted marketing purposes. So far, the development has been slow (I'm still trying to adapt from VBA to VB), but its all starting to make sense now. I'm using two different forms for adding new customers and reviewing the information of existing customers, mainly because the database will grow by about 2,500 customers per year and we wanted to be able to search the records without returning every record when the forms load. Most of this works so far, but I'm having trouble with two issues.
When I open the new customer entry form, I want the form to automatically begin entering data without clicking the "Add New" button. The second problem involves the row ID from the database. It keep showing up as "-1", "-2" etc. The row ID records properly in the table, so no big deal. I have read that this problem is a bug in VB and that its nothing to worry about. However, down the road I will need to access the correct row ID from this same form in order to print out a report for the customer (as needed).
For what its worth here is the code I have so far:
Code:
'Update current record when the form closes
Private Sub frmNewCustomer_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Me.TblCustomersBindingSource.EndEdit()
Me.TblCustomersTableAdapter.Update(Me.dsNewCustomer.tblCustomers)

The following works:
string connectionString = "Provider=Microsoft.Jet.OleDb.4.0;Data Source=" + str_excelFileOnLocalMachineInReports + ";";
connectionString += "Extended Properties=Excel 8.0;";
OleDbCommand myCommand = new OleDbCommand("Select * from [pFACTData$];");
[Code]..
But as soon as I change any of the numbers to doubles (e.g. 23.32457) I get a crash (it doesnt crash on the insert, it crashes on the next one:)The INSERT INTO statement contains the following unknown field name: '23#2345'. Make sure you have typed the name correctly, and try the operation again.

Ok here goes my stab in the dark again: I would like to be able to insert a number in to a list box in the correct order, at the moment the number gets put at the end, but the list box starts negative and then gets larger and the values that will be added are within the range already there, My guess would be some sort of sort function?
listbox1.items.add"inorder"(textbox1.text)orlistbox1.items.sort.add(textbox1.text)
i have seen addrange as a function. can you also tell me if i am starting to think like a VB ((novice) programmer?

I am having some trouble getting the correct syntax for a bit if code. I am using vb to insert data into a db and outputting the data as XML, here is the code
<WebMethod()> _
Public Function addTrack(ByVal tTitle As String, ByVal tAlbum As String, ByVal tGenre As String) As String
Dim conn As New SqlConnection("Data Source=MARTIN-LAPTOPSQLEXPRESS;Initial Catalog=mp3_playlists;Integrated Security=True")
Dim sql As String = "INSERT INTO Tracks (trackTitle, trackAlbum, trackGenre) VALUES ('" & tTitle & "', '" & tAlbum & "', '" & tGenre & "') FOR XML AUTO, ELEMENTS"
[code]....
The code is for a ASP.NET web service, when I click invoke on the website i get the error Incorrect syntax near the keyword 'FOR'. If I remove FOR XML AUTO, ELEMENTS everything works find, db updates but I dont get the data to output as XML. I think the issue is with the brackets required for the insert values because this issue does not occur if the SQL statement is a SELECT statement which has no brackets but i just cant figure out the correct syntax?

I 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)

I have this form that acts as a patient history form, so when I click the "New record" button I want the form to be ready for new input and for it to save the data when I'm done. I also need a button to delete records, but I am completely terrible with databases so I have no idea what I need to do to add records. I assume I can just have the form clear to be ready for the input but I don't know how to get it to save the data.
The whole thing works in Access but I guess that's older VB or something, they were using the acRecord to be able to cycle through all the records of the database. What is VB.net's equivalent?

I am learning MS Access by reading books and i have no formal education on computers. I am trying to insert one record from a form (not bound to any table) by using VBA - Class Module. When following codes are run, the dialogue for parameter value of A and B are opened instead of using the value of variable A and B which is the value of txtbox1 and txtbox2 respectively .
Dim MySql as string Dim A as string
Dim B As String A = me.txtbox1.value B = me.txtbox2.value
MySql = "INSERT INTO tblcom (fieldA,fieldtB) VALUE (A,B)"

I made a window for the purpose of managing "profile" records
while the navigation and updating is working
i cannot seem to get insertion working, as well[code]...
when i press add, i get a new empty record, when i fill it in, i see that the collection sees it, as there is an onform listbox showing the profiles, and it gets listed there, so its actually attached to the list, but the savechanges command does not insert it into the db
there may be some validation errors upon insert, but then i would get some indication, right? now its just silently failing. as if i never tied to commit changes

I am using VB.Net in Visual Studio 2008 with a connected SQL Server Compact Database but for some reason I can not get a record to insert into my Database from my Windows Form.I have used the data connection on the form already to populate a couple of combo boxes but when it comes to commiting the data the sub runs through but there is no additional data in my database.my code is as follows
Private Sub cmdAddQuote_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddQuote.Click
Dim cnData As New SqlCeConnection
Dim cdData As SqlCeCommand[code]......
Teh table only contains these 4 fields and another field which is an automatically generated number called nbrQuoteID .All of the fields are number fields but I have tried sending them as text to see if it made a difference (Threw up an error) but it didn't.
