[RESOLVED] [2008] How to add animated alert to a datetime ?!

[HOTFIX]

Hi everybody…

I’m newbie in vb.net…

I’ve created a vb.net form which contain two datetimepicker by the following format “ddd dd MMM yyyy HH:mm” , a button and three PictureBoxs.

Form Descriptions:
DateTimePicker1: stored datetime value using application setting
DateTimePicker2: current datetime value
Button1: send the value of current datetime to stored datetime
Green image (OK)
Yellow image (Attention)
Red image (Urgent)

I want to add animated alert related to the values in datetimepickers current and stored datetime by the following situations:-

Situation 1- When the current datetime value of datetimepicker is difference of two days and above of stored datetime value:
Green image (OK) steady visible=true
Yellow image (Attention) visible=false
Red image (Urgent) visible=false
*For example if the current datetime is “Tue 07 Oct 2008 17:15” and the stored datetime is “Fri 10 Oct 2008 17:15” the green image will be visible & steady , other images are hidden until the next situation.

Situation 2- When the current datetime value of datetimepicker reach two day before stored date at time 06:30
Green image (OK) visible=false
Yellow image (Attention) blinks visible=true
Red image (Urgent) visible=false
*For example if the current datetime is “Mon 07 Oct 2008 06:30” and the stored datetime is “Fri 10 Oct 2008 17:15” the Yellow image will be visible & blinks, other images are hidden until the next situation.

Situation 3- When the current datetime value of datetimepicker is equal of stored datetime value at time 06:30
Green image (OK) visible=false
Yellow image (Attention) visible=false
Red image (Urgent) blinks visible=true
*For example if the current datetime is “Fri 10 Oct 2008 06:30” and the stored datetime is “Fri 10 Oct 2008 17:15” the Red image will be visible & blinks, other images are hidden until the next situation.

Please any suggestions and ideas
Regards…

You should look at the ErrorProvider class. You can add one to your form and then associate it with one or more controls. It can display an Icon of your choosing, which you can set at design time or in code, and it can be set to blink or not. You can just handle the ValueChanged event of your DateTimePicker and then set the ErrorProvider properties accordingly.

Animated images cannot be used with ErrorProvider but may be you use animated icons.

From the first post it looks like the only "animation" that's required is blinking, which the ErrorProvider specifically does support.

Hi jmcilhinney...

Can please provide me the vb.net codes calculation of three situations alert using the ErrorProvider class because my programming knowledge level in vb.net is very low…

Just change the icon and blinkstyle of the error provider for each of the three possible situations.

Here's your chance to improve it. Have you read the documentation for the ErrorProvider class? Have you created a test project and experimented with it to see what effect each member has? THAT is how you learn. How do you suppose I know how to use an ErrorProvider?

Hi…
I found the codes for datetime alert…

Public Class Form1
    Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
        My.Settings.Save()
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.DateTimePicker1.DataBindings.Add(New System.Windows.Forms.Binding("Value", _
                                            Global.DateTimeAlert.My.MySettings.Default, "Date1", _
                                            True, System.Windows.Forms.DataSourceUpdateMode.OnPropertyChanged))
        ShowErrorIcon()
    End Sub

    Private Sub ShowErrorIcon()
        Try
            Me.ErrorProvider1.SetIconPadding(Me.DateTimePicker1, 5)
            Select Case DateDiff(DateInterval.Day, Now, Me.DateTimePicker1.Value)
                Case Is > 2
                    Me.ErrorProvider1.Icon = My.Resources.OK
                    Me.ErrorProvider1.SetError(Me.DateTimePicker1, "more than two days")
                    Me.ErrorProvider1.BlinkStyle = ErrorBlinkStyle.NeverBlink
                Case Is < 1
                    Me.ErrorProvider1.Icon = My.Resources.Urgent
                    Me.ErrorProvider1.SetError(Me.DateTimePicker1, "less than one day")
                    Me.ErrorProvider1.BlinkStyle = ErrorBlinkStyle.AlwaysBlink
                    Me.ErrorProvider1.BlinkRate = 100
                Case Else
                    Me.ErrorProvider1.Icon = My.Resources.Attention
                    Me.ErrorProvider1.SetError(Me.DateTimePicker1, "between one and two days")
                    Me.ErrorProvider1.BlinkStyle = ErrorBlinkStyle.AlwaysBlink
                    Me.ErrorProvider1.BlinkRate = 800
            End Select
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        ShowErrorIcon()
    End Sub
End Class

Unfortunately I couldn’t figure out how to make it work with more than one dateTimePickers (multi DateTimePickers)..

Please Help…

Delete the ErrorProvider1 control that you have added in design mode and use the code below. It creates the new instance of error provider control for each date time picker control at run-time. I have modified your code a little bit. See if that suits your requirements.

Private Sub Form1_Load( _
  ByVal sender As System.Object, _
  ByVal e As System.EventArgs _
) Handles MyBase.Load
 
  Me.DateTimePicker1.DataBindings.Add(New System.Windows.Forms.Binding("Value", _
                                      Global.DateTimeAlert.My.MySettings.Default, "Date1", _
                                      True, System.Windows.Forms.DataSourceUpdateMode.OnPropertyChanged))
  ShowErrorIcon(DateTimePicker1)
  ShowErrorIcon(DateTimePicker2)
  ShowErrorIcon(DateTimePicker3)
End Sub
 
Private Sub ShowErrorIcon(ByVal dtPicker As DateTimePicker)
  Dim errProvider As ErrorProvider
 
  Try
    errProvider = New ErrorProvider
    errProvider.SetIconPadding(dtPicker, 5)
 
    Select Case DateDiff(DateInterval.Day, Now, dtPicker.Value)
      Case Is > 2
        errProvider.Icon = My.Resources.OK
        errProvider.SetError(dtPicker, "more than two days")
        errProvider.BlinkStyle = ErrorBlinkStyle.NeverBlink
      Case Is < 1
        errProvider.Icon = My.Resources.Urgent
        errProvider.SetError(dtPicker, "less than one day")
        errProvider.BlinkStyle = ErrorBlinkStyle.AlwaysBlink
        errProvider.BlinkRate = 100
      Case Else
        errProvider.Icon = My.Resources.Attention
        errProvider.SetError(dtPicker, "between one and two days")
        errProvider.BlinkStyle = ErrorBlinkStyle.AlwaysBlink
        errProvider.BlinkRate = 800
    End Select
 
  Catch ex As Exception
    MessageBox.Show(ex.Message)
  End Try
End Sub
