Catch a wrong value

[Patrick C. Simonds]

I am looking for something that will catch if the user does not enter a
valid time. For example if they were to enter 0995 instead of 0955.

What I need is if they do enter a wrong value that a msgbox would pop up
telling them there value was not correct and then reselect the textbox so
that the value can be changed.


Below is my code as it stands now.

Private Sub TextBox11_AfterUpdate()

TextBox11.Value = Format(Application.Text(Replace(TextBox11.Value, ":",
""), "00\:00"), "hh:mm")

If TextBox12.Value > "" Then
If TextBox11.Value > "" Then

TextBox13.Value = (TimeValue(TextBox12.Value) -
TimeValue(TextBox11.Value)) * 24
TextBox13.Value = Format(TextBox13.Value, "0.0000")

TextBox1.Value = CDbl("0" & TextBox13.Value) + CDbl("0" &
TextBox23.Value) + CDbl("0" & TextBox33.Value) + CDbl("0" & TextBox43.Value)
+ CDbl("0" & TextBox53.Value) + CDbl("0" & TextBox63.Value) + CDbl("0" &
TextBox14.Value) + CDbl("0" & TextBox24.Value) + CDbl("0" & TextBox34.Value)
+ CDbl("0" & TextBox44.Value) + CDbl("0" & TextBox54.Value) + CDbl("0" &
TextBox64.Value)
TextBox1.Text = Format(TextBox1.Text, "0.0000")

End If
End If


'Test that to see if hours worked exceeds shift length

If TextBox12.Value > "" Then
If TextBox11.Value > "" Then

TextBox2 = TextBox4 - TextBox1

End If

If TextBox2.Value < 0 Then
TextBox2.Value = 0
GoTo Finished
End If

TextBox2 = TextBox4 - TextBox1
TextBox2.Text = Format(TextBox2.Text, "0.0000")

End If

Finished:

If TextBox12.Value = "" Then
TextBox13.Value = ""
End If

If TextBox11.Value = "" Then
TextBox13.Value = ""
End If

End Sub

One way:

Debug.Print IsDate("09:95"), IsDate("09:55")

or

Debug.Print IsDate(Format("0955","00\:00"))

TextBox11.Value = Format(Application.Text(Replace(TextBox11.Value, ":",

""), "00\:00"), "hh:mm")

First off, you don't need to use the worksheet's Text function to do the
above... VB's Format function can do it.

TextBox11.Value = Format(Format(Replace(TextBox11.Value, ":", ""),
"00\:00"), "hh:mm")

However, you need to break that line up into two lines in order to test if
the input is a valid time...

TestDateVariable = Format(Replace(TextBox11.Value, ":", ""), "00\:00")
If IsDate(TestDateVariable) Then
TextBox11.Value = Format(TestDateVariable, "hh:mm")
'
' Rest of your code goes here
'
Else
MsgBox "That is not a valid time value!!!"
'
' Not sure what you will want to do next
'
End If

After the msgbox is dismissed I need TextBox11 to be active.

 

[Rick Rothstein]

Try using this to activate the TextBox...

TextBox11.SetFocus

 

[Patrick C. Simonds]

That does not take you back to TextBox11

Try using this to activate the TextBox...

TextBox11.SetFocus

I just realized... you are using the AfterUpdate event. Why? What are you
doing that you think you need to use this event?

 

[Pats]

It causes some calculations to take place on the UserForm. I had originally
used an OnChange event but it was not working consistently when the user
clicked on the next cell. The AfterUpdate event has not failed no matter
where the user clicked next.

 

[Rick Rothstein]

I have not made use of the AfterUpdate event myself, but the help files for
it seems to suggest that using the BeforeUpdate event might work for you...
it has a Cancel argument that if set to True, will keep the focus on your
TextBox. Maybe moving the validation code there would be a way to go?
