Copy / Duplicate child BO

ksavoie — Thu, 19 May 2011 13:24:31 GMT

I've been ask by my client to add a "duplicate" function to my windows form application in VB.NET 2005, using CSLA 2.

I'm looked into the copy of the object. I tried to use the following code, but it's not doing what I need.

Public Shared Function NewCost(ByVal oldCost As Customer) as Cost
Return CType(DataPortal.Create(New CopyCriteria(oldCost)), Cost)
End Function

<Serializable()>
Private Class CopyCriteria
   Public OldCost as Cost
   Public Sub New(ByVal oldCostas Cost)
        Me.OldCost = oldCost
   End Sub
End Class

I have a one Contract, with a list of Cost. I want to be able to duplicate the Contract Information and the first Cost, so CostID = 0.

How would I duplicate/copy only the information of the CostID = 0? I tried to find a solution online, but without success.

Can anybody help me with this one? Examples of code would be great.

SmartDate - I want textbox to be empty

ksavoie — Thu, 14 Apr 2011 16:17:09 GMT

I'm at the end of my options with the SmartDate.

This is my code.

Private _contrSdtDt As SmartDate = New SmartDate(True)

Public

Property ContrSdtDt() As DateTime
Get
CanReadProperty("ContrSdtDt", True)
Return _contrSdtDt.Date
End Get

Set(ByVal value As DateTime)
      CanWriteProperty("ContrSdtDt", True)
      If Not _contrSdtDt.Equals(value) Then
           _contrSdtDt.Date = value
           PropertyHasChanged("ContrSdtDt")
      End If
End Set
End Property

In my textbox, when creating a new record, I keep getting the "0001-01-01" value, because my date is empty, but that's not what I want. I actually want an empty string, so an empty textbox. I'm using a mask "9999-99-99" for that specific textbox in my window form. And I set the DataBindings.text to my ContrSdtDt.

Can anybody help me on how to get my empty value show up in my textbox in window form?

Thanks

Re: Localisation Rule descriptions

ksavoie — Tue, 29 Mar 2011 15:57:15 GMT

I know this is an old posting, but I'm looking into using the Localization in my custom Validation rules.

Would it be possible to get an example on how it would be done. I've created my custom Validation rules ok and they work fine. I using windows form (vb.net 2005 with CSLA 2.0), and my users have the option to change the language of the application. With this I need to be able to show the error message in the different language.

I've used the following code to access the resources files:

Dim mRS As New ResourceManager("frmMain", System.Reflection.Assembly.Load("frmMain"))

And in my custom rule this is the code I'm using:

e.Description = mRS.GetString("Invoice_Name")

When I do this, I get a Fetch failed (DataPortal.Fetch failed, Message: "Exception has been thrown by the target of an invocation."). I've tried a few things, and when I thought I had the right code, I was getting a Serialization exception on the save.

So do you think it would be possible to get an example on localization to help me out?

Thanks

Validation

ksavoie — Wed, 26 Jan 2011 15:50:58 GMT

We are using CSLA version 2.0 on .NET 2.0 VS2005. In my project, I'm using a datagridview, with child data. In the design, we add extra rows to the datagridview on the Fetch. We do this so that the user doesn't have to add additional rows; they are only allowed a certain number. Any ways that works great, I specify the mandatory fields (all the ID's that I need), and the rows are added to my Datagridview.

In the datagridview, we have a column which does the calculation of other columns. So I created a new property "Public ReadOnly Property TotalEstCost() As String". Here is the bit of code...

Private _totalEstCost As String = String.Empty

Public ReadOnly Property TotalEstCost() As String
Get
'Declare the variables
Dim decTaxAmount As Decimal
Dim decEstimCost As Decimal
Dim decTotalEstCost As Decimal
Dim strTotalEstCost As String

If GSTHSTAmount <> "" Then
decTaxAmount = Decimal.Parse(GSTHSTAmount)
Else
decTaxAmount = 0
End If

If CstAmtDlrsStr <> "" Then
decEstimCost = Decimal.Parse(CstAmtDlrsStr)
Else
decEstimCost = 0
End If

decTotalEstCost = decTaxAmount + decEstimCost

If decTotalEstCost = 0 Then
strTotalEstCost = String.Empty
Else
strTotalEstCost = decTotalEstCost
End If

_totalEstCost = "0.00"

Return strTotalEstCost

End Get

there might be some unnecessary coding... but I'm trying everything now... Like I said everything works fine, until I add the Validation rules.

These are my validation rule that's giving me problems...

' Total Cost
' Rule # 2008
ValidationRules.AddRule(AddressOf Csla.Validation.CommonRules.StringRequired, "TotalEstCost")

ValidationRules.AddRule(AddressOf Csla.Validation.CommonRules.RegExMatch, New Csla.Validation.CommonRules.RegExRuleArgs("TotalEstCost", "^\d{1,11}(?:\.\d\d)?$"))

ValidationRules.AddRule(AddressOf Csla.Validation.CommonRules.StringMaxLength, New Csla.Validation.CommonRules.MaxLengthRuleArgs("TotalEstCost", 13))

When I load my windows form, I keep getting the red warning on the empty rows and when I try to save it obviously doesn't save because of validation issue.

Can anybody help me with this one. Am I making a mistake i the way I created my property or my declaration of my variable. Any help would be greatly appreciated.

Thanks

Saving in windows form

ksavoie — Thu, 20 Jan 2011 15:20:03 GMT

We are using CSLA version 2.0 on .NET 2.0 VS2005. We notice something and we don't know if we are the only one that this happens to and if there's a fix for it. So here it is...

We build our Windows form no problem, we can fetch the information no problem. When we do a modification in a field, let's say a textbox, and we don't tab out of that field (i.e. the cursor is still in the textbox I just modified) and I click my save button, the modification I made in that particular textbox does not get save. But if I do tab out everything gets save.

This is getting a bit of a pain when I'm testing. I have to make sure that I tab out of the field or click out of the field for the changes to be saved.

Is there a work around for this issue?

We don't want to change to CSLA Version 3, because everything is working fine for now and we are too advanced in our project to switch now... We will be upgrading later on.

Thanks

Kat
