I have an application program to submit help tickets. The problem is the error messages are only supposed to pop up when someone doesn't format it correctly but it either don't or comes up after typing when there is no errors. The next issue is my msgbox for lblvalidate doesn't even show up when you hit submit. Can someone please help me?

Question

I have an application program to submit help tickets. The problem is the error messages are only supposed to pop up when someone doesn't format it correctly but it either don't or comes up after typing when there is no errors. The next issue is my msgbox for lblvalidate doesn't even show up when you hit submit. Can someone please help me?

Here's the code:
' Program Name: Help Desk Request
' Author: Corinne Hosington
' Date: February 22, 2017
' Purpose: This web application allows college staff to fill in a web form requesting help from a computer help desk.

Option Strict On

Partial Class _Default
Inherits Page

Protected Sub btnSubmit_Click(sender As Object, e As EventArgs) Handles btnSubmit.Click
' This btnSubmit_Click event will place a help ticket for users submitting requests.

' Declare and Initialize Variables
Dim strMessage As String
Dim strFName As String
Dim strLName As String
Dim strEmail As String
Dim intPhone As Integer
Dim intLabNum As Integer
Dim intCompStat As Integer

' Trim additional spaces that are entered by the user
strFName = txtFName.Text.Trim
strLName = txtLName.Text.Trim
strEmail = txtEmail.Text.Trim
lblValidate.Text = ""
If (strFName = "") Then
rfvFName.Visible = True
Else
rfvFName.Visible = False
If (strLName = "") Then
rfvLName.Visible = True
Else
rfvLName.Visible = False
End If
If (strEmail = "") Then
revEmail.Visible = True
Else
revEmail.Visible = False
End If
If (intPhone <= 9) Then
revPhone.Visible = True
Else
revPhone.Visible = False
End If
If (intLabNum >= 15) Then
rfvLabNum.Visible = True
Else
rfvLabNum.Visible = False
End If
If (intCompStat >= 30) Then
rfvCompStat.Visible = True
Else
rfvCompStat.Visible = False
End If
strMessage = "An order has been placed for " & " " _
& strFName & strLName & " "
strMessage = "Email address: " & strEmail & " " strMessage = "Phone: " & intPhone & " " strMessage = "Lab number " & intLabNum & " " & " and " & "station number " & intCompStat
lblValidate.Text = strMessage
End If
End Sub
End Class

Sorry its not formatted the way it is in VS but I tried to fix it and thats the best I could do.

Answer 1

Based on the code provided, there are a few issues that need to be addressed. Here are the steps to fix them:

Step 1: Fix the if-else statements' indentation issue
- Ensure that the if-else statements are indented correctly to avoid confusion and improve readability.
- Example:

```vb
If (strFName = "") Then
rfvFName.Visible = True
Else
rfvFName.Visible = False
If (strLName = "") Then
rfvLName.Visible = True
Else
rfvLName.Visible = False
End If
' ...
End If
```

Step 2: Check the conditions for error messages
- Review the conditions for displaying error messages and make sure they are correct.
- Example:

```vb
If (intPhone <= 9) Then ' Check if the integer value of intPhone is less than or equal to 9
revPhone.Visible = True
Else
revPhone.Visible = False
End If
```

Step 3: Concatenate string values correctly
- When concatenating strings, use the "&" operator to connect them.
- Example:

```vb
strMessage = "Email address: " & strEmail & " "
strMessage = "Phone: " & intPhone & " "
```

Step 4: Update the assignment of strMessage
- Currently, the strMessage variable is overwritten multiple times.
- Update the assignments to concatenate the values properly.
- Example:

```vb
strMessage = "An order has been placed for " & " " & strFName & strLName & " "
strMessage &= "Email address: " & strEmail & " "
strMessage &= "Phone: " & intPhone & " "
strMessage &= "Lab number " & intLabNum & " "
strMessage &= " and " & "station number " & intCompStat
```

Step 5: Update the validation label
- Assign the final value of strMessage to lblValidate.Text to display the formatted message.
- Example:

```vb
lblValidate.Text = strMessage
```

After making these changes, test the code again and verify that the error messages pop up correctly and the lblvalidate messagebox appears when submitting the form.

Answer 2

Based on the provided code, I can see a few issues that may be causing the problems you mentioned. Let's go through each issue:

1. Error messages not displaying correctly:
In your code, the error messages are being displayed for each validation case. However, the logic for hiding these error messages seems to be incomplete. You need to set the visibility of the error messages appropriately based on the validation results. Here's an example of how you can modify the code to correctly handle the error messages:

```vb
lblValidate.Text = ""
if (strFName = "") Then
rfvFName.Visible = True
lblValidate.Text = "First Name is required."
else
rfvFName.Visible = False
end if
' ... repeat the same for other fields
```

You need to repeat this logic for each validation check and update the error messages accordingly.

2. lblvalidate not showing:
I noticed that you are updating `lblValidate.Text` variable multiple times without concatenating the values. This means that the previous values will be overridden, and only the last assignment will be displayed. To fix this, you can use string concatenation to build the message progressively:

```vb
strMessage = "An order has been placed for " & " " & strFName & strLName & " "
strMessage = "Email address: " & strEmail & " "
strMessage = "Phone: " & intPhone & " "
strMessage = "Lab number " & intLabNum & " " & " and " & "station number " & intCompStat

lblValidate.Text = strMessage
```

In the above code, I've used the `&` operator to concatenate the strings, so that each line of information is appended to the `strMessage`.

Please apply these modifications to your code and see if it resolves the issues you mentioned.
