[dba-VB] .net piddly warnings

I would change the code to read as...

        Dim str As New StringBuilder
        For Each lstcSysVar In Me.List
            str.Append(" " & lstcSysVar.pValue.ToString)
        Return str.ToString()

The StringBuilder class is more efficient than the old string concatenation
routines in classic VB.

I am getting a lot of warnings like 

Variable Umptiumpt used before it is assigned a value.  The following code
causes such a warning:

        Dim str As String
        For Each lstcSysVar In Me.List
            str = str & " " & lstcSysVar.pValue.ToString
        Return str

This is quite common methodology and would require the quite unnecessary 
	str = ""

After the dim statement to avoid the warning.

Is there any way to acknowledge the warning and cause it to go away,
preferably for specific instances (lines) of code?  It seems that unless you
just always do the variable initialization you are going to end up with
hundreds of useless warnings masking real warnings that you wish to be made
aware of.
