Many To Many DB And Inserting
Jun 25, 2011
I'm trying to do an Insert into a couple tables on one form with data controls. The problem is I don't know the approach. You see, the client has books to sell. He has catagories and he wants to add many catagories for each book. One or more catagories. It would seem to me that this is a many to many normalization. Being that one or more catagories can belong to one or more books? If this is incorrect, please tell me, as I thought it was a one to many earlier with one book having one or more catagories? Anyway, I need to be able to allow the client to enter one book, and then assign one or more catagories? He wants the potential buyers to be able to query books by catagories obviously. Wondering what approach to use? What data controls, and is it possible with just the controls, or do I need to write a stored procedure to grab the ID from the book using the @@Identity SQL statment?

My problem is when I try adding a new appointment I get an error that says ""Column 'AppID' does not allow nulls."" Editing existing appointments is fine and it updates the DB no problem. I don't have an INSERT statement right now (which might be the issue) so I was thinking of doing this: INSERT INTO [tablename] ( [column1], [column2], ... ) VALUES ( [value1], [value2], ...) Only problem with that is I would need to use the textbox names for the VALUES, and that form that pops up to gather appointment info is from a third party, and I can't find the names of any text boxes

I have the following code:
Code:
Imports System.Data.SqlClient
Public Class Form1
Dim ReturnValue As Object = Nothing
[Code].....
which should return back the next available sunday to me from the database. What I'm getting back is 01/01/0001 - 01/08/0001.
I've tried a couple of versions of this but they all produce the same date.

Basically I am trying to insert some data about a user into a database for a test that they complete. If it's their first time completing the test then I want their results to be automatically stored. If not then I want their results to only be overwritten if they agree to it.
Here's my code so far:
Dim sqlx As OleDbCommand = New OleDbCommand

I've written the following code to add a new record to a database:
Public Shared Sub AddTopicUser(ByVal UserID As Integer, ByVal TopicCode As String)
Dim RowsAffected As Integer
Dim ATUDCONN As New OleDbConnection
ATUDCONN.ConnectionString = DBCONNSTR
Dim ATUDCMD As New OleDbCommand("INSERT INTO tblSubscriptions (UserID, TopicCode, Completed) Values (@UserID, @TopicCode, @Completed)", ATUDCONN)
[Code]...
I recieve no errors from the code, but when i open the database after - the record has not been added.
I have checked that the values being passed as parameters to the function are valid. I was curious as to whether I was formatting the OleDbCmd correctly, which is why i added a message box function to show be the value of the connection string which at runtime is: when they're not being added to the db?

I am having problems with inserting into my sql database my program is as follows:[code]So when I enter my data, into my program, it goes perfectly until it gets to "dim num as integer = cmd.ExecuteNonQuery" and then it comes up with an error saying "Syntax error in INSERT INTO statement.".i am also doing an update function which is pretty much exactly like this, except for the sql command of course, and that works perfectly with this code.[code]I have noted that instead of"replace" it should be "insert" but am now getting another error where it says "Conversion from string "#PlayerNo#" to type 'Integer' is not valid."

I have a SQL Compact Database that I've added in my Data Sources. I then have a DataGridView which is filled with all the records in a particular Data Set.There's a button on the same form as the DataGridView that opens another form, which allows the user to add a new row (record) to the DataSet. Currently however, the fields on this form are not related to the columns in the Data Source in any way.

I have recently created a disk catalog program for myself, it is working fine. The problem is, when i try to index my 2 TB HDD, the time taken to write 66K rows into sql table is taking a lot of time nearing 30min.
I am using sql client (sdf is the file extension).
Also, i am using two threads to insert data simultaneous saving 50% of time.
I am using vb generated table adapters only.

I have a button called btnUpdate and when I click on update I want the program to check to see if the ID number already exists within the database but I cant seem to figure out how to do that.

Im prting a values to my Database which will later be pulled to make HTML Reports. So Im needing to insert "<br>" Every 50 characters so the values isnt displayed as one big long string.I do have it to do it at the first 50 chars. But since Im writing it to a Database My code looks like so:
cmd.Parameters.Add(New OleDbParameter("@Notes", txtcustnotes.Text.Insert(50, "<br>")))
And it works for the first 50, but not for the next 50. Any tips to make it do every 50 chars and still write properly to the DB?

So I have the following that seems to work fine in MS SQL Server management Studio and seems (but isn't) to be working as its doing a re-direct to another page after the insertion of data...Basically, I pull in all the data from the text boxes and hidden fields, convert that info to strings and do my insert statement. Now in MS SQL SMS The following insert statement works:
insert into [Contacts].[dbo].[contactInformation] values ('Adam', 'john', '16', '' , '' , 'm', '', '');
You can tell from the above which are allowed and which are not allowed to be null. any ways. Why is this not inserting data into my database? is it because of
cmd.CommandText = SqlDataSourceCommandType.Text

Im brand new to programming. Apart from doing a few digital dashboards in excel i have zero experience with vb or creating code. You may need to be patient.What i am trying to do is from my form, browse to a pic in a folder and insert it into a picture box in the program. the pic should insert itself into the program after it has been selected, and the picture should resize itself to fit the pic box (or viceversa if need be)
I have looked at some similar threads on this issue but none of the code in those solutions is working for me.

I am pulling data from one SQL Server database, formating the data and then inserting it into another SQL Server Database. I am looking for a faster way to do this than the one I am currently using. The data pull is about 37,000 rows, so formating it and inserting it one row at a time is very time consuming. I was hoping I could format it into a datatable and insert the datatable into second database essentially inserting all rows at the same time as if they wre within the same databse, but I have not found a way to do this.
Essentially the code (I have simplified it) that I am using...

cn1 As New SqlClient.SqlConnection

How can I insert a hyphen after each 3 characters in a textbox? For example, if in the text box there are: ABCDEFGHIJKLMNOP. how can I insert a hyphen between each 3 letters automatically? The result would then be ABC-DEF-GHI-JKL-MNO-P. I have come to a way but it's not a practical one, i.e I used Insert(,"-") but then lines are filled with conditions slowing down the application.

having problems getting one of 2 pictures displayed when I run the program. In a whole, this is a coin tossing program that, after the toss button is pushed, is supposed to show either a coin heads or tails image while also displaying True or False for heads or tails respectively. Additionally, a running tally of how many times heads and tails is displayed.The main issue right now is that when I press the toss button, no image is displayed, but True or False is displayed as well as the running number. After checking, running numbers correspond with the T/F results. The secondary issue is that a running tally is displayed, but instead of it being in a single or double digit increasing format, it shows up as 0011122223345666 as you keep pushing the toss button. I've researched books and the web to find out where I'm going wrong and to get more clarification on why it's not showing, but I haven't been able to decisive.

Dim randomObject As New Random()
Dim headscount As Integer
