New blog address

Hi,

Please note that I have split my old blog argurosblog in two parts.
I have noticed that looking at some computer programming code with the next post being about a pasta or rice dish was not working very well.

This is my blog about computing

Matlab Excel Link from VBA configuration

To create macros that use Excel Link functions, you must first configure Excel to reference the functions from the Excel Link add-in. From the Visual Basic environment pull down the Insert menu and select Module.When the Module page opens, pull down the Tools menu and select References.... In the References window, check the box for EXCLLINK.XLA and click OK. You may have to use Browse to find the EXCLLINK.XLA file.

If you use MLGetMatrix in a macro subroutine, enter MatlabRequest on the line after MLGetMatrix. MatlabRequest initializes internal Excel Link variables and enables MLGetMatrix to function in a subroutine. For example,

Sub Get_RangeA()
  MLGetMatrix "A", "RangeA"
  MatlabRequest

End Sub

Do not include MatlabRequest in a macro function unless the function is called from a subroutine.

Excel how to show all value in a filtered table in vba

Hi,

If you want to show all value from a filter table, you need to check if there the table is filtered first, otherwise the Sheet1.ShowAllData will fail.
This is the solution

With  Sheet1
    If .AutoFilterMode Then
        If .FilterMode Then
            .ShowAllData
        End If
    End If
End With

How to Create a task or appointment using VBA Code in outlook

Hi,
I have changed the original code at this link to show you how to create either a task or an appointment from an e-mail item.
This is very handy when you want quickly create task/appointment without wasting your time to attach the original mail.
The only problem is that the item is attached at the end of the file. This is due to a bug in Outlook 2008/2010 for which the postion item does not work.
Just copy and paste the code below into an outlook module to make it work.

Sub CreateTaskFromMail()
  Const mailItem_c As String = "MailItem"
    Dim OE As Outlook.Explorer
    Dim MI As Outlook.MailItem
    Dim AI As Outlook.AppointmentItem
    Dim TI As Outlook.TaskItem
     
    Set OE = Application.ActiveExplorer
     
     'Abort sub if no item selected:
    If OE.Selection.Count < 1 Then
        MsgBox "Please select an already saved message before" & vbCrLf & _
        "attempting to create a task" & vbCrLf & _
        "with this button ...", vbInformation, "No message selected ..."
        Exit Sub
         'Abort sub if item selected is not a MailItem.
    ElseIf TypeName(OE.Selection(1)) <> mailItem_c Then

How to call a parametric stored procedure from Microsoft Excel Query

Hi,
This is a very nice trick to call a stored procedure with parameters from excel.

If you type for example

exec model.GetPrices (?,?,?,?)

or

CALL model.GetPrices (?,?,?,?)




you will get this message

"Parameters are not allowed in queries that can't be displayed graphically"

while instead if you put the second Call within {} like that


{CALL model.GetPrices (?,?,?,?)}

it will work!!!

How to use build a mail system framework in Excel using OOP: Example

I will explain how to use the framework to build a new mail object using the framework I have build

Let'us suppose we want to build a mail to trade a Total Return Swap to be send to a broker

 1) Interface Layer: We first create a ITrsMailDataProvider and define its interface

Option Explicit

Public Function RetrieveBody(irsId As String, fundId As String) As Parameters

'No Code Here
End Function

Public Function RetrieveHeader(irsId As String, fundId As String) As HeaderDTO
'No Code Here
End Function

 2) DAL:  We then create a TrsMailDataExcelProvider that implements teh ITrsMailDataProvider interface. You   can use some mock data for testing. If you are getting data from Access just go ahead and create your TRSMailDataAccessProvider that implements the same interface

2) Interface Layer: Then we need to Create a IProviderFactory. This will be the abstract factory that define the abstract methods that return our interface ITrsMailDataProvider or a  IIrsMailDataProvider. The idea is that the abstract providers will be produced by your abstract factory. The business layer will use only those interface and will know nothing about which concrete provider it is in use

   This class will look like
   Class IProviderFactory
       GetTrsMailDataProvider as ITrsMailDataProvider  //only method signature
       GetIrsMailDataProvider as  IIrsMailDataProvider  //only method signature
   End Class

3) DAL Layer: We then need a class that implement the IProviderFactory. For Example a ExcelProviderFactory will take care to create of the MailDataProvider that have Excel as source.

Option Explicit

Implements IProviderFactory

Private mTrsMailDataProvider As TrsMailDataExcelProvider
Private mIrsMailDataProvider As IrsMailDataExcelProvider

Private Function IProviderFactory_GetIrsMailDataProvider() As IIrsMailDataProvider
      If mIrsMailDataProvider Is Nothing Then
         Set mIrsMailDataProvider = New IrsMailDataExcelProvider
      Else
         'Do Nothing
      End If
      Set IProviderFactory_GetIrsMailDataProvider = mIrsMailDataProvider
      
End Function

Private Function IProviderFactory_GetTrsMailDataProvider() As ITrsMailDataProvider
     If mTrsMailDataProvider Is Nothing Then
         Set mTrsMailDataProvider = New TrsMailDataExcelProvider
      Else
         'Do Nothing
      End If
      
      Set IProviderFactory_GetTrsMailDataProvider = mTrsMailDataProvider
End Function

4) BLL: Finally we will have the client of the Abstract Factory, as for the Abstract factory Pattern. We will call this class the DataProvider (this can be a static class in c# ore moduel in VBA) and it will sit in the business Layer. This Class has the main objective to
use the IProviderFactory interface to produce our Trs and Irs MailDataProvider. The diffuclt part here is that this class should istantiate a Real istance of the abstract class IProviderFactory, but as we know we want the business Layer to be agnostic of the DAL. To get this result in C# we can use reflection. We can just write a method so that it loads a .dll specified in a config file as a string, and create an istance of a class from this dll.
This way to reference to the DAL Layer are necessary. In VB 6.0 this is can be done with CreateObject.

Option Explicit

Private mFactory As IProviderFactory

Public Function IrsMail() As IIrsMailDataProvider
  Set IrsMail = Factory.GetIrsMailDataProvider()
End Function

Public Function TrsMail() As ITrsMailDataProvider
  Set TrsMail = Factory.GetTrsMailDataProvider()
End Function

Private Function Factory() As IProviderFactory
'Insert Code here
'This cose should use a config file and reflection to choose
'which concrete factory instantiate. Createobject could be used in VB 6.0
'to make this class decouple with the DAL Layer
'We keep things ease here.

 If (mFactory Is Nothing) Then
     Set mFactory = New ExcelProviderFactory 'I really should be using CreateObject
                                             'to keep the class decoupled from the DAL
 End If
 Set Factory = mFactory
 
End Function

4) So fare we have done the following
    a) Business Layer -->  Interface Layer -->; DataBase Layer
    b) In the Interface Layer we have implemented the Model Provider Pattern and the Abstract Factory Pattern. Those class are just interface that define the methods that the business Layer can call to accesss the data
    c) In the DAL we have the real providers that just implement the provider interfaces and the real factory that just implement the factory methods.
    d) The transfer of the data between DAL and Business Layer is done using some object that are on the common layer such as MailDTO (data transfer object) or the Parameters collections (this is an utility object)
    e) The client of the abstract factory, the one we called DataProvider, is in the BLL and it stores in as a private field a reference to the IProviderFactory. This is where the magic happen: we can just switch the RealProvider withouth having to change any of the code that regards the BLL or Interface Layer.
