Creating Digital Signature for VBA Project (Outlook VBA / Excel VBA/ Word VBA)

How to digitally sign a VBA Project

To create a code-signing certificate, follow these steps:

From Programs menu, choose Microsoft Office -> Microsoft Office Tools -> Digital Certificate for VBA Projects

(or)

Navigate to the folder where your Office applications are installed, usually C:\Program
Files\Microsoft Office\Office12 for Office 2007 and run the Selfcert.exe program.

<>

SelfCert.exe is provided with Office 2000 and later. If it is not installed on your system, run Office Setup and install Office Tools  Digital Signature for VBA Projects.

Type a name for your certificate – just use your own name or product name and click OK to create your personal code-signing certificate.

<>

Now open the VBA project using Alt+F11 and select Tools ➪ Digital Signature
to open the dialog shown below. In this dialog, click the Choose button and select the
certificate and click OK twice to choose your certificate and
sign your code project with that certificate.

Save your VBA project; then exit and restart Application (Excel / Word / Outlook).
When you open your VBA project next time, you will be prompted to enable your macros in
the dialog shown below

You can use this dialog to trust your certificate by selecting the option to “Always trust macros from this publisher”, which prevents this dialog from appearing again, or you can just enable the macros for that session.

Click the Trust All Documents from This Publisher button to trust your code-signing certificate
and add it to the trusted publishers list. If you open the Trust Center dialog shown
again and click the Trusted Publishers area, you will now see your code-signing certificate listed
as a trusted publisher.

The same certificate can be used for multiple projects.

How to use .Net Array.Sort Function in VBA

Using Vb.Net Function in VBA

How to use a VB.Net DLL/TLB in Excel VBA

Here is an example for using the customized .NET Function in Excel VBA. Unfortunately EXcel VBA doesn’t have a Array.Sort function. To overcome the shortcomings, we create our own function here in .Net and use the same in Excel VBA

Here are the steps:

1. Create a class library project in Visual Studio
2. Add a COM Class item (DND_SortArray in this example)
3. In the assembly information edit the title, company and provide a meaningful description. This would be seen in the References dialog in Excel
4. Add the code shown below:

_

1. Public Class DotNetDud_SortArray

   #Region “COM GUIDs”

   ‘ These GUIDs provide the COM identity for this class

   ‘ and its COM interfaces. If you change them, existing

   ‘ clients will no longer be able to access the class.

   Public Const ClassId As String = “93534c94-9fc1-4a54-b022-338fa7d454c1″

   Public Const InterfaceId As String = “03787ed3-bc65-41a1-9053-d37f390ff94b”

   Public Const EventsId As String = “34d12c14-8afd-44b7-a987-fc2f909724b6″

   #End Region

   ‘ A creatable COM class must have a Public Sub New()

   ‘ with no parameters, otherwise, the class will not be

   ‘ registered in the COM registry and cannot be created

   ‘ via CreateObject.

   Public Sub New()

   MyBase.New()

   End Sub

   Public Sub SortArray(ByRef arTemp() As String)

   Array.Sort(arTemp)

   End Sub

   End Class

Compile the Project. You will get a DLL and a TLB.

Now open the Excel VBA Editor and add the TLB file to References.

The following code will now use the SortArray .NET Function created

Sub Use_DotNet_Sort()

Dim Cls1 As DotNetDud_SortArray.DotNetDud_SortArray

Set Cls1 = New DotNetDud_SortArray.DotNetDud_SortArray

Dim arTemp(0 To 2) As String

arTemp(0) = “Bottle”

arTemp(1) = “Apple”

arTemp(2) = “Aaron”

Cls1.SortArray arTemp

Set Cls1 = Nothing

End Sub

Validate Date between Ranges using VBA

Validate Dates

Validate Date between Ranges

Sub Feed_Check_Date_Function()

‘ Date is within the Valid Range
Check_Date “2007-05-01″, “2007-05-10″, “2007-05-01″

‘ Date is NOT within the Valid Range
Check_Date “2007-05-01″, “2007-05-10″, “2007-05-21″

End Sub

Function Check_Date(ByVal StartDate As Date, ByVal EndDate As Date, ByVal DateTobeChecked As Date)

If DateDiff(“d”, StartDate, DateTobeChecked) <> 0 Then
MsgBox “Enter a correct date!!!”
End If

End Function

Check Workbook Attributes

Get File Attributes – GetAttr

Sub Check_Workbook_Attributes()

Dim oXL As Excel.Application
Dim oWB As Workbook

Set oXL = Excel.Application

oXL.DisplayAlerts = False

‘ Check if the Workbook is Read-Only. If it is then close the workbbok

Set oWB = oXL.Workbooks.Open(Filename:=”c:\MyBook.xls”, ReadOnly:=False)

If oWB.ReadOnly = True Then
MsgBox “The Workbook is Read-Only!!”, vbInformation
oWB.Close False
End If

oXL.DisplayAlerts = True

‘ Using the GetAttr Function, WE can check if the file is read-only
If (GetAttr(“c:\MyBook.xls”) And vbReadOnly) Then
MsgBox “The Workbook is Read-Only!!”, vbInformation
End If

End Sub

The GetAttr function will work if the file has read-only attributes. If the file is locked and hence it is available as read only this will not be useful

Resizing Text Boxes Automatically

Automaticaly Resize Text Boxes

Resizing Text Boxes

Sub Initialize_TextBox()

‘ To automatically resize the text box set the AutoSize to True. This will resize the text box as the user types text

TextBox1.AutoSize = True

‘ The sizing can be limited by providing the maximum length using MaxLength property

TextBox1.MaxLength = 20

‘ You can inform the user of resing with the Tooltip.

TextBox1.ControlTipText = “Maximum Length is 20″

End Sub

ControlTipText is the VBA variant for Visual Basic ToolTipText

If Data.GetFormat(vbCFFiles) = True Then

End If
End If

‘ ——————————————

This will be used to show the file name in the Text Box if a file is dragged and dropped into it
