Put In The Text Box That The Database Will Accept?

Jul 8, 2009

BirthDate Data Column

DataType System.DateTime
DefaultValue <DBNull>
NullValue (Throw exception)

A text box is bound to the field.My question is: what (empty, nothing or null) value can I put in the text box that the database will accept.

Textbox - Text Box To Only Accept Numbers?

Apr 2, 2012

I'm fairly new to VB.net (self taught) and was just wondering if someone out there could help me out with some code. I'm not trying to do anything to invovled, just have a textbox that takes numeric value from 1 to 10. I don't want it to take a string or any number above 10. If some types a word or character an error message will appear, telling them to enter a valid number. This is what I have, obviously it's not great as I am having problems.

Create A Text Box That Will Accept Numbers In The Currency Format?

Aug 2, 2009

I need to create a control for input a currecncies to a field. I'm planning to use a Textbox.

This is the format of the text box for currencies:

"XXXXXXXX.XX"

the dot "." must be fixed in the textbox and it should be loaded with the textbox. Furthermroe i have plans to code eachtime a user enters a number it should print the numbers from Right ot left.

eg: When user enters Number 1234.34

When the user enter these number they should display them as:

when user enters 1

0000.01

when the user enters 2:

0000.12

when the user enter 3:0001.23

When the user enters 4:

0012.34

When the user enters 3:0123.43

When the user enters 4:(after entering all digits in the number)1234.34

Could any one give a couple of ideas how to creat these kind of boxes?

I was thinking about creating a custom control (a Textbox) but still i need to have a the above format in the textbox!

Loading Text (strings) From A Database Into A Label.text (so Text From Database Shows Up Into Label)

Apr 4, 2011

I have a form that I am loading text (strings) from a database into a label.text (so the text from the database shows up into the label) I have done this code in a class that keeps all my database stuff seperate.

Public Function getQuestions() As List(Of String)
Dim question As New List(Of String)
objConnection.Open()
objReader = objcommand.ExecuteReader

[CODE]...

Within the form that the label is in I have done this code

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text(db.getQuestions().ToArray)
End Sub

I am basically making a quiz, so that when the form loads, question 1 is on there is 4 possible answers. You then press next button and it goes to the next question.

VBA - How To Accept A Download

Oct 12, 2011

I have a VBA script that connects to a site.On that site, it puts in criteria to filter on a database. It then submits it.A pop up window appears asking to Open / Save / Cancel. I don't know how to interact with that window.It is possible to Save, and specify the download location without having to use Sendkeys?Note: There is no file to directly download. You have to run the report and it kicks back the file.I know this is VBA, but I think VB.NET has probably has the same result.
