DB/Reporting :: Adding New Record On Form Load - Show Correct Row ID

May 5, 2008

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)
[Code] .....

Textbox - Copy/paste Program - Particular Field To Show When Paste It

Nov 20, 2011

I have a small copy/paste type of program. You put text in the boxes, click copy and it copies it to the clipboard. I have a text file attached to format the text when it is copied. what I want to accomplish is...If I don't fill in every single textbox with text, I don't want that particular field to show when I paste it. Example, I have the layout like below on the text document.

textbox1.
textbox2.
textbox3.

No matter what, when I click copy, the text document is going to copy textbox1,2,and 3. If I only put text in textbox 1 and 3, I don't want it to copy textbox2 if its empty.

Oct 30, 2008

This error has me completely baffled. There is no indication (that I ca FinD as to what field won't handle the information. Heres the situation:I am using an Accees query to insert a new record in a table with 49 fields. Of these fields, 1 is an integer, 7 are booleans and the other 41 are text fields. The text fields represent either Time of Day or a Timespan.

My field sizes are:

For time of day 8 digits(example 08:00 AM)
For a time span 5 digits(example 03:30) I will never exceed 2 digits for
hours

I have checked every field in the dtatbase and they are all as noted. I am at a loss as to how to proceed.

SQL Record Search But Field Is Sometimes NULL?

Mar 2, 2010

I am trying to do a SQL query to see if an Address already exists in my database. My addresses are structure like this:

line1
line2
line3
city
state
zipcode
country

Sometimes line2 and line3 are NULL values in my database.I am using .NET TableAdapter and DataTable to make my query. When I try to pass in my line2 parameter (@line2) it is equal to a string with value = nothing. My database does not interpret this as NULL and says the records don't match, but I know they do? How do I pass in a string = nothing and have it compare to a NULL value in the database as being equal? I have tried string = DBNULL.value but won't compile.I have done similar comparisons with integers etc. using integer = Nullable (of integer) but this does not exist for strings.

DB/Reporting :: Simple Database Field Editing?

I know this sounds simple to the majority of the database gurus out there but I am finding it difficult to find anything related.I am using Visual Studio 2008 VB.net winforms application.I have a form which contains a datagridview. what I want to do by push of a button is set the field "OnHand" either to default or 0. The 'either or' is really for you guys. Which ever one works the best in terms of reducing code or functionality is obviouls prefered.Once the 'OnHand' Fields in every record has changed then I would like to save all the data back to the database'This is more than likely very simple I just cannot find anything that discusses this kind of thing.

DB / Reporting - Create The XML That A Record Set Can Load

Mar 7, 2010

I have a dataset; I want to create an equivalent record set. What I really want to do is create the XML that a record set can load; I have no other use for the record set per se. I want to be able to load recordsets on other machines (which use VB6 ins of vb.net) with this data. I found some code that loops through the columns in the dataset and creates the fields in the record set; that's executing. However, the code given to open the record set fails with "incompatible or incorrect parameters" or some such. [Code] I can see that a recordset is a construct meant to bridge between running code and a data store of some sort, but in this case the data is "stored" in the dataset, not anywhere else. I want to put that data in the XML form that the recordset uses, so that other code that can only use recordsets (ins of datasets) will be able to read it.

I just want to add a value from a textbox/variable and save it as a new record in a MS Access Database after a button click.

I've set up the database, set up the tables required.

From what I gather, I need to first link declare 'Imports System.Data' outside all the code. And also define a variable as a connection (Dim con As New OleDb.OleDbConnection) then access the database with "con.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = PathName").
