Messagebox

Hello!! VB.NET 2003
I am so new at this it isn't funny. I am right now programming a fun little test that people take in order to find out their life expectancy. Any how it is a 3 page application and before the user clicks the "Next Page" button I want the program to catch any questions that haven't been answered.

The questions are asked and then the user fills in 1 of 2 radio buttons that are grouped together by the panel control.

What I want is instead of having multiple boxes pop up when the user forgets to answer more than one question, I want only one box that states "You have not answered Question#: 1, 5, and 10. You need to answer these before moving on to the next page" And I don't want the user to be able to go to the next page until these fields have been filled in. Down below I will put what I have if someone could help me out I would be so greatful Thanks!!! PS... as it stands my code won't even let me get to the second page anyways....This can be awfully frustrating


PrivateSub btnNext_Click(ByVal sender AsObject, ByVal e As System.EventArgs) Handles btnNext.Click
If mypart1.rdoYes01.Checked = FalseAnd mypart1.rdoNo01.Checked = FalseThen
MessageBox.Show("Hey!! You need to answer number 1!")
EndIf
If mypart1.rdoYes02.Checked = FalseAnd mypart1.rdoNo02.Checked = FalseThen
MessageBox.Show("Hey!! You need to answer number 2!")
EndIf
If mypart1.rdoYes03.Checked = FalseAnd mypart1.rdoNo03.Checked = FalseThen
MessageBox.Show("Hey!! You need to answer number 3!")
EndIf
If mypart1.rdoYes04.Checked = FalseAnd mypart1.rdoNo04.Checked = FalseThen
MessageBox.Show("Hey!! You need to answer number 4!")
EndIf
If mypart1.rdoYes05.Checked = FalseAnd mypart1.rdoNo05.Checked = FalseThen
MessageBox.Show("Hey!! You need to answer number 5!")
EndIf
If mypart1.rdoYes06.Checked = FalseAnd mypart1.rdoNo06.Checked = FalseThen
MessageBox.Show("Hey!! You need to answer number 6!")
EndIf
If mypart1.rdoYes07.Checked = FalseAnd mypart1.rdoNo07.Checked = FalseThen
MessageBox.Show("Hey!! You need to answer number 7!")
EndIf
If mypart1.rdoYes08.Checked = FalseAnd mypart1.rdoNo08.Checked = FalseThen
MessageBox.Show("Hey!! You need to answer number 8!")
EndIf
If mypart1.rdoYes09.Checked = FalseAnd mypart1.rdoNo09.Checked = FalseThen
MessageBox.Show("Hey!! You need to answer number 9!")
EndIf
If mypart1.rdoYes10.Checked = FalseAnd mypart1.rdoNo10.Checked = FalseThen
MessageBox.Show("Hey!! You need to answer number 10!")
EndIf
ExitSub
mypart2 = New part2
mypart2.Show()
mypart1.Hide()
EndSub

It really depends how customised you want the message to be. The simplest way would be to just start with an empty string an append the numbers of any unanswered questions, separated by commas. You would then append that string to another string that says "Hey!! You need to answer numbers " and show that in a message box. You can then customise that so that the last number has "and' before it instead of a comma, and also to use "number" instead of "numbers" if there is only one.

You might want to also check out the error provider control as well.

Thank you so much for your help. All of you. A beginners class/book can only get you so far. It is neat being able to have this out here to learn beyond the scope of the book.

Crush,
Those articles are very useful, I read them about a week or more ago and was able to put my knowledge to use with them. The problem is and I did a quick second glance to be sure and I don't think it covered if you were validating. Meaning first you want to complete validation on page one before it lets you get to page two. The problem I am having is, it stops you from going to the next page so the user can complete the validation but it won't let you pass to the second page now at all even if the validation is complete.
