Need Help

i have a textbox and when the user key in 1000000

it will change the format to 10,000.00

and when user key in 1000050 it will help me to change the format to 10,000.50

can i know how to change the format ???? without click any button

===========================================
Private Sub gross_TextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles gross_TextBox.TextChanged

gross_TextBox.Text = Format(Val(gross_TextBox.Text), "#,###.##")

taxable_TextBox.Text = Val(gross_TextBox.Text) + Val(bonus_TextBox.Text) - Val(children_TextBox.Text) - Val(personal_TextBox.Text) - Val(parent_TextBox.Text) - Val(epf_TextBox.Text)

End Sub
===========================================

I think the problem is, you are providing optional characters for the end of your format string, try this:

VB Code:

Private Sub TextBox1_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
        Dim GIDollars As Double = Val(Me.TextBox1.Text)
 
        Me.TextBox1.Text = Format(GIDollars, "#,###.00")
    End Sub

if i add in the coding above i get a problem is that the textbox event will get a problem that all the textbox cannot be sum up

coz every textbox i have an event that is sum it up

if i change the format of the text box it will give me the wrong answer

example if i enter 1000

at the textbox show me 1,000.00

but the textbox that show me the sum of it just display 1

and give me an idea how to do ?

well, my first guess would be that there is no text in your other textboxes so you are trying to perform calculations with values of nothing.

What you should do is have form level variables that hold adjustments to your calculations, then in each text box you should implement a handler that captures the changed value and assigns it to the module level variable and then performs the calculation on those variables.

Try this:

VB Code:

Private GIDollars As Decimal = 0
    Private Deductions As Int16 = 0
    Private Parents As Int16 = 0
    Private Bonus As Decimal = 0
    Private Personal As Decimal = 0
    Private EPF As Decimal = 0
 
 
    Private Sub gross_TextBox_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles gross_TextBox.Leave
        GIDollars = Val(Me.gross_TextBox.Text)
        Me.gross_TextBox.Text = Format(GIDollars, "#,###.00")
        Me.taxable_TextBox.Text = Format(GIDollars + Bonus - Deductions - Personal - Parents - EPF, "#,###.00")
    End Sub
 
    Private Sub bonus_TextBox_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles bonus_TextBox.Leave
        Bonus = Val(Me.bonus_TextBox.Text)
        Me.bonus_TextBox.Text = Format(Bonus, "#,###.00")
        Me.taxable_TextBox.Text = Format(GIDollars + Bonus - Deductions - Personal - Parents - EPF, "#,###.00")
    End Sub

sorry, i got a new problem after i change the coding below the gross textbox only can enter not more than 5 value

example 100.00 is the maximum number

when i add in one more 0 it change become 1.00

not 1,000.00 what is the problem is that ??

and i only can enter the 0 between the 1 and the .00 what make it happen ??

Private Sub gross_TextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles gross_TextBox.TextChanged

TempGIDollars = Val(Me.gross_TextBox.Text)
TempBonus = Val(Me.bonus_TextBox.Text)
TempChildren = Val(Me.children_TextBox.Text)
TempPersonal = Val(Me.personal_TextBox.Text)
TempParents = Val(Me.parent_TextBox.Text)
TempEPF = Val(Me.epf_TextBox.Text)

Me.gross_TextBox.Text = Format(TempGIDollars, "#,###.00")
Me.taxable_TextBox.Text = Format(TempGIDollars + TempBonus - TempChildren - TempPersonal - TempParents - TempEPF, "#,###.00")


End Sub

The TextChanged event fires with every keystroke, so everytime you press a key, this event fires. I would recommend against using this event for the purpose specified. Use the Leave event.

thanx i will try first

thanx the code is working

if i really wanna use the TextChanged format is there any solution ????

Not without overriding the event's default behavior. The event is self describing and so it should be obvious that any time the text is changed (eg. pressing a key while the control has focus) the event will fire.

ok ~
thanx for helping me

:D

I found some significant errors with the code I provided you earlier. I would suggest trying this in your project, it's much simpler and more easily extensible.

VB Code:

'Form level variables
    Private WithEvents ctl As Control
    Private refCtl As New TextBox
    Private GIDollars As Double = 0
    Private Deductions As Double = 0
    Private Parents As Double = 0
    Private Bonus As Double = 0
    Private Personal As Double = 0
    Private EPF As Double = 0
 
    'Sets the initial reference for ctl to the forms active control
    Private Sub frmComboExample_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Activated
        Me.ctl = Me.ActiveControl
    End Sub
 
    'Single event handler for all controls on the form, can be extended...
    Private Sub ctl_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles ctl.Leave
        'If the length of the text in the text box is 0, an error occurs...
        'Probably better if a try block were here...
        If ctl.GetType.Equals(refCtl.GetType) And ctl.Text.Length < 1 Then Exit Sub
        Select Case ctl.Name
            Case Me.gross_TextBox.Name
                GIDollars = Convert.ToDouble(Me.gross_TextBox.Text)
                ctl.Text = Format(GIDollars, "#,###.00")
            Case Me.bonus_TextBox.Name
                Bonus = Convert.ToDouble(Me.bonus_TextBox.Text)
                ctl.Text = Format(Bonus, "#,###.00")
        End Select
        Me.ctl = Me.ActiveControl
        Me.taxable_TextBox.Text = Format(GIDollars + Bonus - Deductions - Personal - Parents - EPF, "#,###.00")
    End Sub

ok ~
thanx for the helping
this will make me learn more

thanx for your help ~
