Two quick questions...

1. I'm using ComboBox with enumerated lists.  How do I override the enumeration text in the ComboBox dropdownlist ?

2. I'm trying to work with a BO entirely from code (C#) - creation, calling a method on the BO and finally disposing.  I am getting blind onto the correct way of doing this.  HELP......

Looking forward to hear from you all ;-)

Regards
Ulrik

For this you can use the < EnumDispayValue() > from the MicroFour.StrataFrame.Tools, here is sample in VB:





Imports MicroFour.StrataFrame.Tools



Public Enum eMailSendFormat As Integer

< EnumDisplayValue("Acrobat (PDF)") > _

Acrobat_PDF = 1



< EnumDisplayValue("Comma Separated Values (Windows-CSV)") > _

CSV = 2

End Enum

I am not sure I totaly understand your request here, but here is sample in VB of how to use a SF BO:



Using bo As bizItems = New bizItems

bo.FillByPrimaryKey(pPK_Items)

If bo.Count = 1 Then

Return bo.ItemName

Else

Return String.Empty

End If

End Using

C# versions:



To change text displayed in an SF combo that is loaded from an enum, set an attribute on each item within the enum:



using MicroFour.StrataFrame.Tools



public enum eMailSendFormat {

  // This will now display "Acrobat (PDF)" in combo

  [EnumDisplayValue("Acrobat (PDF)")]

  Acrobat_PDF = 1;



  // This will now display "Comma Separated Values (Windows-CSV)" in combo

  [EnumDisplayValue("Comma Separated Values (Windows-CSV)")]

  CSV = 2;

}




The 'using' statement in C# (Using in VB.NET) are used to ensure that disposable objects get disposed. I.e. when the using block is exited, the item is disposed. This occurs whether the code runs it course, you break out of it or an exception occurs within the block.



using CustomerBO customers = new CustomerBO() {

  customers.FillByCity("Munich");

} // calls customers.Dispose() automatically when this block exits

Greg, thanks for the C# translation Hehe
