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.
Thanks,

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.

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

When I enter a non-numeric value into a numeric field, vb auto validates the field and the system does not allow me to proceed to fill the next text box.
How can I work around this? I want to write code to perform the validation on the numeric.
This is what happened as shown in picture. I cannot continue to input other fields.
field
There is probably an event handler that is limiting the input to numeric fields and possibly setting the focus on the textbox. This could be in Keydown, Leave, TextChanged, or some other events. You can replace this validation code with your own.
I am working on a MS Word form for a client where they want the ability to count the number of words, check spelling, have a character limit, and have the rest of the form locked down so that the end user cannot change anything they are not supposed to. I have attempted to convince them that word count and character limit are redundant if we have proper instructions, however, this is what they want. They also want the form to be able to "work" even if the user does not enable macros, meaning, they want it locked and a character limit first and foremost.
I know that if we just rich text content controls and put the form into a group spell check and word count word while also "locking" the remainder of the form, except user content controls do not allow for character limits and using legacy/activex controls in a grouped form locks those controls as well.
So, for now, I have settled on using the ActiveX Textbox (this is negotiable if I have a reason to use the legacy textbox) and have achieved the minimum "workability" (if that's even a word). The only way I have figured out to check the spelling is below:
Sub chkSpelling()
Activedocument.Tables(1).Rows(26).Cells(1).Range.Text = txtRole.Text
Activedocument.Tables(1).Rows(26).Cells(1).Range.checkSpelling
txtRole.Text = Activedocument.Tables(1).Rows(26).Cells(1).Range.Text
'... so on and so forth throughout each text box
End Sub
The issue is that this is not good enough for my standards. Printing the text of each textbox (up to 1700 characters) at the bottom of the screen each time I need to check the Spelling is unacceptable. Does anyone else have any ideas?
Thank you for your assistance.
Answer with help from #bibadia
Dim doc As Document
Set doc = Documents.Add(, , wdNewBlankDocument, False)
doc.Paragraphs(1).Range.Text = txtRole.Text
doc.Paragraphs(1).Range.CheckSpelling
txtRole.Text = Replace(doc.Paragraphs(1).Range.Text, Chr(13), "")
Use CreateObject to create a new word instance
Ensure .Visible = False (I think that is the default)
Create a new document in that instance.
Copy the text to be checked into that
Spell check.
Remove the document and the Word instance.
If I understand your question correctly then,
I need to check the Spelling is unacceptable. Does anyone else have any ideas?
If text boxes are named with numbers, you might be able to use loop, and save your coding lines with time.
want the form to be able to "work" even if the user does not enable macros
If user did not enable macros, he would not be able to see form (is it User Form, you want to say) and no background macro code would run. (Tested on Ms-Excel 2007), ultimately failing all.
regarding text box control on user form
yes that can be set to character limit from properties menu, and spell check can be done using your method.
Set range2 = Documents("MyDocument.doc").Sections(2).Range
range2.CheckSpelling IgnoreUpperCase:=False, _
CustomDictionary:="MyWork.Dic", _
CustomDictionary2:="MyTechnical.Dic"
is there a method of setting up my datagridview to show me textboxcolumns until editmode is entered? At which time I will swap some textboxcolumns for bound comboboxcolumns. And at the end of validation/exit edit mode I can swap back?
If there's a method of doing this please share some links to examples.
I wouldn't try to switch DataGridView ColumnTypes like that. Sounds like a bad time.
Is your goal to have a DataGridViewComboBoxColumn that does not display the ComboBox dropdown button when it's not being edited? If so, there are two options:
Set the column's DataGridViewComboBoxColumn.DisplayStyleForCurrentCellOnly property to True.
Create your own DGV column based on the ComboBox by extending DataGridViewTextBoxCell. MSDN has a great article for doing this with the Calendar control here.
Of course you can. In the properties of the datagridview you can drill down to the column proprieties and switch the datatype to combo box. Very straight forward and easy.
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.

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.
