ParametersUsed Always Polulated after calling ReportingService.Ren

In SSRS 2000 SP2 the documentation for ReportingService.Render states that
the ParametersUsed output parameter should only be populated only if the
report being rendered is a report history snapshot. I'm invoking the Render
method with a null HistoryId as follows, so I would expect the ParametersUsed
output parameter not to get populated.
results = m_RptService.Render(m_RptCatalogItem.Path /*Report*/,
m_Format /*Format*/,
null /*HistoryID*/,
null /*DeviceInfo*/,
m_RptParameters /*Parameters*/,
null /*Credentials*/,
null /*ShowHideToggle*/,
out encoding /*Encoding*/,
out mimeType /*MimeType*/,
out historyParms /*ParametersUsed*/,
out warnings /*Warnings*/,
out streamIDs /*StreamIds*/);
The call generates the following HTTP traffic. As you can see the HistoryId
is not sent in the request yet ParametersUsed is populated in the result. If
I'm interpreting the documentation correctly this value should not be
populated in the response. I really don't what ParametersUsed to be
populated in the response. Is this the correct behavior?

application produces the following output "Length: 3" indicating that the
ParametersUsed output parameter was populated even though no histryid was

According to the following documentation this does not seem like the correct
behavior (http://msdn2.microsoft.com/en-us/library/aa258532(SQL.80).aspx).
Notice that the description for ParametersUsed states that the output
parameter is only populated of a history snapshot is being rendered. This
causes fairly significant performance issues for me because in some cases I
am passing large parameters. Instead of these parameters just being in the
request, they are in both the request and the response causing the response
to be much larger than I desire.

Parameters in url to make GIF question.

What parameter can I send from my app that will render the report and
then instantly convert it into a .GIF file?
thanks,
TrintTrint,
There isn't a parameter you can pass to get an exported parameter as a gif
file.
Take a look at the url below to view supported export formats:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rswork/htm/rwp_workingreports_v1_3nxt.asp
The below link shows the available URL access params:

for TIFF you supply
rsFormat=IMAGE along with other report parameters.

I figured out how to render .gif...here it is:
"The Image rendering extension renders a report to a bitmap or
metafile. By default, the Image rendering extension produces a TIFF
file of the report, which can be viewed in multiple pages. When the
client receives the image, it can be displayed in an image viewer and
printed.
The Image rendering extension can generate files in any of the formats
supported by GDI+: BMP, EMF, GIF, JPEG, PNG, and TIFF. For TIFF format,
the file name of the primary stream is ReportName.tif. For all other
formats, which render as a single page per file, the file name is
ReportName_Page.ext where ext is the file extension for the chosen
format.

Parameters ignored, Render report from VB .Net application

I seem to be unable to pass parameters from a VB .Net application to Reporting Services.

Before I added the parameters to the query, I got all the rows back. So I know the application is basically working. Now that I have added the parameters, I get nothing.

I thought the SetExecutionParameters function would help, but my syntax is wrong and it fails.

I would appreciate any hint as to what step I am missing.

Report setup:

Parameters

Name Value
@.Report =Parameters!Report.Value
@.Corp =Parameters!Corp.Value
@.Dept =Parameters!Dept.Value

Query conditions

WHERE Report = 'BudgetVarianceSummary'
AND PeriodEnd = CONVERT(DateTime,CONVERT(char,GETDATE()- DATEPART(day,GETDATE()),112))
AND Report = @.Report
AND Corp = @.Corp
AND Dept = @.Dept

VB Code snippet:

Dim reportPath As String = "/FinancialReports/BudgetVarianceSummary"
