Macro Function to Determine If Environment Is 32-bit

MORE INFORMATION

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.

Visual Basic Code Example

   Function is32Bit() As Boolean
      is32Bit = False 'Assume Failure
      If InStr(1, Application.OperatingSystem, "32", 1) > 1 Then
         is32Bit = True
      End If
   End Function
 
   Sub TestIT()
      msgbox is32bit
   End Sub
				

Using the Example

Microsoft Excel 97:

1. In Microsoft Excel, create a new workbook.
2. Press ALT+F11 to start the Visual Basic Editor.
3. On the Insert menu, click Module.
4. Type the sample macro in the code window of the module.
5. On the Tools menu, click Macros. Click TestIt and click Run.
   
   NOTE: When you run the macro, a message box appears. In the message box, True appears if you are using a 32-bit environment. False appears if you are using a 16-bit environment.

Microsoft Excel 5.0 and 7.0:

1. In Microsoft Excel, create a new workbook.
2. On the Insert menu, point to Macro, and then click Module.
3. On the new module sheet, type the sample code in this article.
4. On the Tools menu, click Macro. Click TestIt and click Run.
   
   NOTE: When you run Microsoft Excel version 5.0c (16-bit) under Windows 95 or Windows NT, this function returns False. This is by design because Microsoft Excel version 5.0c is a 16-bit application.

It may be possible to work around this situation by creating a macro that makes calls to the Windows application programming interface (API). This type of programming is supported by the Windows Software Development Kit (SDK) and the Visual Basic, Professional Edition, support groups. The level of support you can receive from these groups depends on the individual support policies of the group. (Microsoft Support professionals may not be able to assist in specific construction of macros that use API programming.) If you have limited programming experience, you may want to consult one of the Microsoft Solution Providers. Solution Providers offer a wide range of fee- based services, including creating custom macros.
