Report Props – select Code and drop this vbs function in. It is referenced in a cell via the prefix Code.
i.e. =Code.BlankZeroRow(Fields!FieldName.Value, “datasetName”),4)

Average & Min values can check for numbers less than reporting precision and not count them so as not to report zero values as minimum and skew average values by inflating the count with zero values collected:

=Min(iif(Fields!fieldName.Value > 0.009, Fields!fieldName.Value, Nothing))

=Sum(Fields!fieldName.Value) / IIf(Count(iif(Fields!fieldName.Value > 0.009, 1, Nothing)) = 0, 1, Count(iif(Fields!fieldName.Value > 0.009, 1, Nothing)))

The precision check is for both formatting decimal places and counting values less than the presented precision to be zero. The formatting can be set on the cell (Text Box Props) so may not be necessary. You can probably better use the MOD function for the minimal value check but I have not tested that out yet.

Function BlankZeroRow(VALUE as Double, Precision as Integer)
	Dim sRETURN  as string
	sRETURN = ""	' default blank

	Select Case Precision 	' Test Precision
	Case 0
		If (Value > 0.9) then
			sRETURN =  Format(VALUE,"##0")
		End If
	Case 1
		If (Value > 0.09) then
			sRETURN =  Format(VALUE,"##0.0")
		End If
	Case 2
		If (Value > 0.009) then
			sRETURN =  Format(VALUE,"##0.00")
		End If
	Case 3
		If (Value > 0.0009) then
			sRETURN =  Format(VALUE,"##0.000")
		End If
	Case 4
		If (Value > 0.00009) then
			sRETURN =  Format(VALUE,"##0.0000")
		End If
	Case Else
		If (Value > 0.009) then
			sRETURN =  Format(VALUE,"##0.00")
		End If
	End Select

	BlankZeroRow = sRETURN
End Function

Working with the default breadcrumb in SP2010 I found the following issues: If you have site pages and want to navigate from one to the other you may want to show a hierarchy that does not physically exist in SP (i.e. pages all in site pages).  In addition, certain directories in the path used by SP may lead the user to nowhere useful. Below I have code for a user control that I have added to the v4.masterpage. It is deployed as a feature to ControlTemplates (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\CONTROLTEMPLATES). In VS2010 add blank Sharepoint 2010 project and add new item: Usercontrol.

First the User Control.  This is based on an older project  http://www.codeproject.com/KB/aspnet/breadcrumbs.aspx. I use a simple switch statement to match URL and decide on how to present the node and target URL but hope to read a SPList or a SiteMap for a more manageable solution going forward.

The result of this is a breadcrumb looking like (& linked to) whatever you want. You can ignore a virtual directory, define the label & link or even define multiple ‘nodes’ on your breadcrumb for each directory in the path.

 int nNumDirs = strDirs.Length;

9/21/10 Note: By changing the visible=false attribute you can run into an odd error
“You must specify a value for this required field” See this link for details for a css workaround.

The Masterpage requires a User Control reference, placement of the actual control and visible=’false’ on existing breadcrumbs.

<%@ Register TagPrefix="wssuc" TagName="Breadcrumb" src="~/_controltemplates/SPBreadcrumb/BWBreadcrumb.ascx" %>

Place the control in the banner – use SPD in split mode to navigate and turn off visibility on standard controls until you see what you like.

<td class="s4-titletext"><wssuc:BreadCrumb ID="Test1" runat="server" />
...
<SharePoint:SPLinkButton  Visible="false"  ...
<SharePoint:ClusteredDirectionalSeparatorArrow   Visible="false"  runat="server"/>

Step One: Create HTML Redirection Page on a webserver. I use basic javascript but you probably can find some slick jQuery code out there.

redir.htm

<html>
<head>
<base target="_self" />
<script>

function launch() {

var resourceURL = getQueryVariable("r");

window.open(resourceURL);

}
// A U T O M A T I C A L L Y   C L O S E    P A G E
// js credit due: http://bytes.com/topic/javascript/answers/145577-self-close-window-without-dialog-close-yes-no
var howLong = 1000;      // one second
var t = null;
function closeMe(){
t = setTimeout("self.close()",howLong);
}

// G R A B  T A R G E T  U R L
// js credit due:  http://www.groupsrv.com/dotnet/post-428830.html
function getQueryVariable(variable)
{
var query = window.location.search.substring(1);
var vars = query.split("&");
for (var i=0;i<vars.length;i++)
{
var pair = vars[i].split("=");
if (pair[0] == variable)
{
return pair[1];
}
}
}
</script>
</head>
<body onload="launch();closeMe();">
  <!-- Link To Close But Page Should Close Within 1 second via closeMe() -->
  <a href="javascript:self.close()">click here to close</a>
</body>
</html>

STEP TWO: Add a Blue Help button on the target page.
Change the Help Text properties by Control-V paste
do not click on the ellipsis … and paste in the following
as a single line (no line breaks):

<script>javascript:popup_window=window.showModalDialog("http://MyWebserver/redir.htm?r=http://myHelpFile.pdf",'_parent', "dialogHeight: 100px;");</script>

The onclick event will launch 2 windows and then the target resource url in the ‘r’ querystring variable. The second page redir.htm should self close in a 1 second. I have not been successful automatically removing the base window that is launched – it remains to be manually closed by the user. Please post a comment if you have found a solution to that issue.
