Visual Basic If Statement That Makes The User Check At Least One Box And Radio Button Or They Cannot Continue
Oct 5, 2011
This is what I have so far for the following scenario: I want to have it so that if a users clicks submit without checking a check box from one section it throws up a dialog box that makes the process loop and give them a chance to check a box. The process wont continue until at least one check box is checked. The same thing above goes for my radio buttons as well. Here's my code:

trying to write a simple form for calculating professor's salaries depending on their degree and position.my problem is that the when i select a check box, the value is not being updated until i select a different radio button. it probably doesn't make much sense here,
Public Class frmMain
Private Sub optLecturer_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles optLecturer.CheckedChanged[code]....
the values being assigned to my salary label are correct, but are not being updated until i select a new radio button. im not entirely sure how to get around this so that the value is updated as soon as i select the check box.here's when the program looks like:

I need to perform a calculation based on the idea that the user will select the operation, which is in this label lblOperation. The two numbers, num1 and num2, come from lblNum1 and lblNum 2, which are randomly generated. How can I change the statement to say lblCorrect.Text = the value of num1 and num2 where the operation performed is whatever operation the user chooses from lblOperation.Text? This is what I have so far:
'btnSubmit instructions
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
[Code]....
Instead of always adding the num1 and num2 I want the operation to be between the two numbers and the answer to be printed in lblCorrect.

I have a project in which I have to display a picture box based on:
Which radio box is checked
and
if a checkbox to make the picture box visible is checked. As someone who values clean, good code this is my code and it horrifies me. My question, is there some way to condense the following using cases or some other construct I don't know in VB.net?
If CheckBox1.Checked = False Then
BooksPictureBox.Visible = False
MusicPictureBox.Visible = False
[Code]....
Note- all the images stack on one another, and all of them start without being visible.

Suppose I have 2 radio buttons r1 and r2, both the radio buttons ask for your gender, you can be a man or woman. So what I want: if user checks r1 but then realizes that she is a woman, she then wants to check r2 so the control on r2 gets checked while r1 gets unchecked.
<tr><td>
<asp:Label runat="server" text="Chooose Your Category" ID="lblcategory"></asp:Label>
</td><td>
<asp:RadioButton runat="server" Text="Male" ID="rbgold" />
</td><td>
<asp:RadioButton runat="server" Text="Female" ID="rbsilver" />
</td></tr>
What should I do next so as I can choose only one?

I'm curious if there is a "check all" kind of thing for a tablelayoutpanel? To explain, say I have TableLayoutPanel1 with 6 radio buttons and I'm doing an error check to make sure that at least one radio button has been selected during a click event. Do I have to do If / and with all 6 radio buttons? Or is there something like "If TableLayoutPanel1.checked(obviously not this) = false then".

I need to have 4 text boxes and three command buttons. One button should be used for exiting the program, one button should be used for clearing all of the text boxes, and the last button should be used for any calculations/conversions. You should also have a radio button group for the user to choose entry temperature type.
One text box should be used for the entry of an initial temperature. The radio button group will then allow the user to select the entry temperature. When the button is clicked for conversion, the other three text boxes will populate with answers to the conversion. and if I enter 37 degrees Fahrenheit, the Fahrenheit text box should read 37 after the conversion.)
