Summary: SQLSetEnvAttr sets attributes that govern aspects of environments.

!!!!C# Signature:
 [DllImport("odbc32.dll", SetLastError=true)]
 static extern short SQLSetEnvAttr ( 
	IntPtr envHandle, 
	int attribute, 
	IntPtr attrValue, 
	int stringLength );

!!!!Alternate C# Signature:
[DllImport("odbc32.dll", SetLastError=true)]
 static extern short SQLSetEnvAttr ( 
	IntPtr envHandle, 
	int attribute, 
	int    attrValue, 
	int stringLength );
 
!!!!VB Signature:
 Private Declare Auto Function SQLSetEnvAttr Lib "odbc32.dll" ( _
	ByVal henv As IntPtr, _
	ByVal attribute As Integer, _
	ByVal valuePtr As IntPtr, _
	ByVal strLength As Integer ) As Short

!!!!Notes:
Simple attributes are passed in the pointer itself, hence the overloaded signature.

!!!!Tips & Tricks:

We hit a bug with getting odbc data sources under 64 bit.  Oddly it only seemed to affect people with visual studio 2012 installed.  Maybe the problem is with .NET framework 4.5.  The c# signatures had "ushort attribute" and we changed it to "int attribute".  Then things seemed to work for people with Visual Studio 2010 or 2012.
