In VB Win-forms Application a NumericUpDown Control is used for only to scroll numbers. Its definition is:
The Windows Forms NumericUpDown control looks like a combination of a text box and a pair of arrows that the user can click to adjust a value. The control displays and sets a single numeric value from a list of choices. As Shown here.
I want to use strings instead of numeric values. For example, Grades: "A","B","C", etc. I think I will need to use UserContorl to code another custom "StringUpDown" Control.
You can't add String values to Numeric Drop down. instead for this you can use DomainUpDown here is the code to place a DomainUpDown in your form that contains A - Z characters
Dim domainUpDown1 As DomainUpDown
domainUpDown1 = New System.Windows.Forms.DomainUpDown()
For i As Integer = 65 To 90
domainUpDown1.Items.Add(Chr(i))
Next
Controls.Add(domainUpDown1)
Note : This control is available in Tool box also
You can change values using the ByRef=""
e.g. RefValues="Red;Blue;Green;Brown"
Hope this is what you were looking for

I am trying to put a number picker in a form in MS Access 2007. Here's an example of what I am trying to make:
I cannot find this in the default form controls, and have tried to make one myself using a listbox. Listboxes can be modified to look just like the number picker above, however the arrows only change the view, of the list, and not the actual selection (that is the value). For example, with the list box, if I have it range from 1 to 3, and default at 1 - when I change it to 2 via the arrows, the value of the listbox does not change, and is still one.
Does anyone know how to get a number picker in Access?
So you want to create a list of numbers and allow users to change the value displayed (AND stored as the control's value) using up and down arrows, such that they select the next or previous in the list.
I would suggest creating a text box and two buttons. Populate an array with the list of values. When a button is clicked it would:
A. Find the position in the array of any value already entered into the text box (eg loaded from a database)
B. Get the next or previous item from the array.
The array is populated as required (probably when the form is opened).
If you just need to allow the user to enter a whole integer number (ie a number spinner) you would do as follows:
Create one using a (locked) textbox and two buttons. Just add a textbox (name it something like txtValue) and two buttons (btnUp and btnDown), then add code like this to the Click event of those buttons:
Private Sub btnUp_Click()
Me.txtValue = Nz(Me.txtValue, 0) + 1
End Sub
Private Sub btnDown_Click()
Me.txtValue = Nz(Me.txtValue, 0) - 1
End Sub
You could add if statements to limit the data being entered
Or you can use a 3rd party control.

There are probably more, but be aware that using these sorts of controls in Access is unsupported, and there is no guarantee moving forward that they will work in Access. You're far better off using the native methods described earlier.
I want to set minValue and maxValue of text boxes to define a range of acceptable values for validation purposes.
In VB 6 this is straight forward and can be done under text box properties, however in visual studio vb .net 2010 this is not the case or it may be the case that i am missing something.

In WinForms, there is a NumericUpDown control that you can use, and it has properties for Minimum and Maximum.
What you need is a numeric text box control with according properties. AFAIK MS does not provide one, but there are free solutions available like this one:
http://www.codeproject.com/KB/edit/HDNumericTextBox.aspx
make a customized textbox - thats checks the ascii of the entered value and - restrict the value to numeric., like - try with KeyDown or keypress events of text box and catch the keycode or event sender..
Try using the RangeValidator.
I have a two column list in my combobox and when I choose one of the items in it using the drop down list, it stores (what I see in the textbox part of the combobox) only the value I selected (wether it's the one on the right or left column according to boundcolumn)
My question is: Is there a way to store(or present-that is my goal) in the textbox part of the combobox, both of the columns of one row selected?
For example: [column1] Daniel [column2] Smith. And in the textbox I want: Daniel Smith (and not just Daniel, or Smith on they're own)
What you describe is theoretically possible, but with restrictions.
Even when you didn't ask for that, here comes my idea:
Like described here you can change your ComboBox's text without changing its value. This allows you to 'store' the underlying value while displaying both columns in one.
Listen on the SelectedIndexChanged Event and change the text property as follows:
Sub ComboBox1_SelectedIndexChanged()
ComboBox1.Text = ComboBox1.Column(0) & "-" & ComboBox1.Column(1)
End Sub
(This is only a basic example.) Can't test it right now, but in .Net you can use CType to explicitly convert the sender argument to a ComboBox variable and access it this way.
The Boundcolumn property can't be changed to multiple values. You can try to use VbTab as a delimiter in the text field but i'm not sure how it will appear.
Edit:
Don't forget the default values. I think your Text field should show both columns before the user clicked on the list the first time, too.
You can set a combobox text field to use data from multiple columns but you may need to write some code to do it.

I have a form with a large number of buttons on it, each named btn1 through btn25. I have another button that is generating a random number and saving it to an integer variable intDrawn.
I'd like to know if there's a simple way to alter a particular button based on the result in intDrawn; if intDrawn = 5, then I want to change the font in btn5, for example.
Is there a way to alter a control programmatically like this? I'm using Visual Basic Express 2008.
It sounds like you'd be better to use a control array. Give your buttons the same name and then use the integer result to change the font for that particular control number in the array.
http://msdn.microsoft.com/en-us/library/kxt4418a%28VS.80%29.aspx - VB6
http://msdn.microsoft.com/en-us/library/aa289500%28VS.71%29.aspx - VB.Net
Create a control array of buttons, and then use the index into this array to alter a particular button.
Control Arrays
There is also a "stupid" way to do this. Add an invisible textbox and after getting your random number you can just text1.text = "btn" + randomnumber, and then change the color or whatever you wish using text1.text.
Control Array is the better choice, but you could also achieve it with reflection.
is it possible in design mode to set the textbox text property to the text property of a textbox in a different form in vb.net?
You could use the ApplicationSettings.PropertyBinding property of the text box to accomplish what you want. If you sort the text box properties A-Z, it should be the first one in the list in parenthesis. Just create a shared application value and it will apply to each control that binds to the value.
