Checks for the Cancel button clicks and takes no action.
Sub GetValue2()
UserEntry = InputBox("Enter the value")
If UserEntry <> "" Then range("A1").value = UserEntry
End Sub
Combine InputBox and Do Loop to read user input
Sub GetValue3()
MinVal = 1
MaxVal = 12
Msg = "Enter a value between 1 and 12"
ValidEntry = False
Do
UserEntry = InputBox(Msg)
If IsNumeric(UserEntry) Then
If UserEntry >= 1 And UserEntry <= 12 Then
ValidEntry = True
Else
Msg = "Your previous entry was INVALID. Enter a value between 1 and 12"
End If
End If
If UserEntry = "" Then Exit Sub
Loop Until ValidEntry
ActiveSheet.Range("A1").Value = Val(UserEntry)
End Sub
Get the Password
Sub GetPassword()
Dim sPassWord As String, i As Integer
i = 0
Do
i = i + 1
If i > 3 Then
MsgBox "Sorry, Only three tries"
Exit Sub
End If
sPassWord = InputBox("Enter Password")
Loop Until sPassWord = "XXX"
MsgBox "Welcome"
End Sub
Get the return value from InputBox
Sub InputBoxDemo()
Dim myValue
myValue = InputBox("Please enter number of hours worked", "Hours Worked")
MsgBox myValue
End Sub
How to handle error caused by value from InputBox
Public Sub ErrorHandling()
On Error GoTo ErrorHandling_Err
Dim dblResult As Double " holds the result of the division
dblResult = 10 / InputBox("Enter a number:")
MsgBox "The result is " & dblResult
ErrorHandling_Exit:
Exit Sub
ErrorHandling_Err:
Select Case Err.Number
Case 13 " type mismatch - empty entry
Resume
Case 11 " division by 0
dblResult = 0
Resume Next
Case Else
MsgBox "Oops: " & Err.Description & " - " & Err.Number
Resume ErrorHandling_Exit
End Select
End Sub
It is a good idea to include the title and default arguments to provide the user with a little help in knowing what to enter.
Sub GetRes()
Dim retValue As String
retValue = InputBox("Enter your name.", "Name", "First, Last")
End Sub
Provide help file for InputBox
Sub inputDemo()
Dim strWhichOffice As String
strWhichOffice = InputBox("Enter the name of the office that you visited:", _
"Expense Assistant", "defaultValue", , , _
"c:\Help.chm", 0)
End Sub
Read data from dialog box and fill it into the cell
Sub GetData()
Sales = InputBox(Prompt:="Enter Target Sales")
If Sales = "" Then Exit Sub
Range("B2").Value = Sales
End Sub
Read password from InputBox
Sub GetPassword()
Dim PassWord As String, i As Integer
i = 0
Do
i = i + 1
If i > 3 Then
MsgBox "Sorry, Only three tries"
Exit Sub
End If
PassWord = InputBox("Enter Password")
Loop Until PassWord = "XXX"
MsgBox "Welcome"
End Sub
Reference InputBox from Application
Public Sub InputBoxTest()
Dim Answer As Range
Set Answer = Application.InputBox(prompt:="Enter range", Type:=8)
End Sub
Return a number from InputBox
Sub AddTwoNums()
Dim myPrompt As String
Dim value1 As String
Dim mySum As Single
Const myTitle = "Enter data"
myPrompt = "Enter a number:"
value1 = InputBox(myPrompt, myTitle, 0)
mySum = value1 + 2
MsgBox mySum & "(" & value1 & "+2)"
End Sub
The InputBox function displays a dialog box containing a simple text box
Sub InputBoxExample()
Dim strName As String
strName = InputBox("What is Your Name?", "This is the Title", "This is the Default")
msgBox "You Entered " & strName
End Sub
To make sure that the user has chosen the OK button, check that the input box hasn"t returned a zero-length string
Sub res()
Dim strWhichOffice
strWhichOffice = InputBox("Enter the name of the office:", _
"Expense Assistant 2000", "default", , , _
"c:\Help.chm", 0)
If strWhichOffice = "" Then End
End Sub
To retrieve input from an input box, declare the numeric variable or String variable that will contain it
Sub help()
Dim strWhichOffice
strWhichOffice = _
InputBox("Enter the name of the office:", _
"Expense Assistant 2000", "default", , , _
"c:\Help.chm", 0)
End Sub
Use If and IsNumeric function to check user input
Sub macro_if()
Dim number
number = InputBox("Type in a number, please!")
If Not IsNumeric(number) Then
MsgBox "This is no number!"
ElseIf number > 10 Then
MsgBox "The number is larger than 10."
Else
MsgBox "The number is smaller then or equal 10."
End If
End Sub
Use InputBox to read value for an array
"Option Compare Database
Option Explicit
Public Sub ArrayExample()
Dim i As Integer
Dim intNum(1 To 10) As Integer
For i = 1 To 10
intNum(i) = InputBox("Please enter guess " & i, "Guess!")
Next i
For i = 1 To 10
Debug.Print "Guess number " & i & " = " & intNum(i)
Next i
End Sub
Use parameter name in InputBox function
Sub GetRange()
Dim Rng As Range
On Error Resume Next
Set Rng = Application.InputBox(prompt:="Specify a range:", Type:=8)
If Rng Is Nothing Then Exit Sub
MsgBox "You selected range " & Rng.Address
End Sub
Using the InputBox Function: InputBox(prompt [, title] [, default] [, xpos] [, ypos] [, helpfile, context])
Sub Informant()
InputBox prompt:="Enter your place of birth:" & Chr(13) & " (e.g., Boston, Great Falls, etc.) "
End Sub
Validate the user"s entry.
Sub GetValue3()
MinVal = 1
MaxVal = 12
msg = "Enter a value between 1 and 12"
ValidEntry = False
Do
UserEntry = InputBox(msg)
If IsNumeric(UserEntry) Then
If UserEntry >= 1 And UserEntry <= 12 Then
ValidEntry = True
Else
msg = "Your previous entry was INVALID."
msg = msg & "Enter a value between 1 and 12"
End If
End If
If UserEntry = "" Then Exit Sub
Loop Until ValidEntry
ActiveSheet.range("A1").value = UserEntry
End Sub
Validation with the InputBox() Function
Sub Use()
Dim userName As String
Dim userBirthday As Date
Dim nameOk As Boolean
nameOk = True
Do
userName = InputBox("What is your first and last name?", "Name")
If (userName <> "") Then nameOk = ValidateName(userName)
Loop While (nameOk = False) Or (userName <> "")
End Sub
Function ValidateName(userName As String) As Boolean
Dim strLength As Integer
Dim I As Integer
Dim numSpaces As Integer
Dim tempString As String
Dim msb As Integer
userName = Trim(userName)
strLength = Len(userName)
For I = 1 To strLength
If Left(userName, 1) = " " Then
numSpaces = numSpaces + 1
End If
userName = Right(userName, Len(userName) - 1)
Next I
If (numSpaces <> 1) Then
ValidateName = False
msb = MsgBox("Please enter just two names separated by one space", vbCritical, "Error")
Else
ValidateName = True
End If
End Function
