I've used VB to connect to Excel and get the titles of the different columns in a spreadsheet. These then display in a drop down combo box for the user to choose from. I'm getting lots of empty values in my combo box because not all the columns in Excel have titles. How would I go about telling it not to display them?
Excuse the easy question but I've only started learning to code a week ago.
Running: Win7Pro, VS2010Pro
Try this:
New project (WindowsApplication1), new form (Form1) with one DateTimePicker (DateTimePicker1), one TextBox (TextBox1) and one Button (Button1).
The DateTimePicker's properties changed are: ShowCheckBox: True, Checked: False
The code on the form is:
Public Class Form1
Public Sub New()
' This call is required by the designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call.
Me.DateTimePicker1.Value = DateSerial(2011, 1, 31)

This combo box is databound to a SQL backend, so when it is filled it has a blank at the top of the list. I am assuming this is added because of the NULL at the bottom of the SQL table. Is there a way to remove this entry?
I have tried the following:
.items.remove("") ' does not work, i added this after the population command
.items.removeAt(0) ' This gave me an exception stating that it could not be used because the datasource was used This is the code i use to fill the combobox on form load:
With ManufacturerComboBox
.DisplayMember = "Manufacturer"
.ValueMember = "ManufacturerID"

Problem 2: Why does an additional field from my access database disappear even after I manually created the field?? (access database 2003 version, extension is .mdb) I'm using visual studio 2008
I have searched all over the forums and not found an answer to my question. My question is how do i write to an access database at runtime. The database is also created at runtime. I have a dataset loaded with a table that i needs to be written to the database. how would i write each row of my dataset to my database? Sorry if this sounds a little jumbled together it is late and i am tired. If it is unclear you can ask me and i will answer any questions you have about my question.

Does anyone know what is the best way to check has datetimepicker been clicked and value selected before saving and updating database. I am working on a database app and database field for "Date" does not allow null so in order for app to work properly i would like before saving to check if the date is selected and if not to create warning for user. I have created that for "Name" and other columns, but those are text boxes so I had no problem with that. I could change the database field for "Date" to allow null, but that the easyer way and not what I really want. If someone has solution for problem
