VS的Service Pack4可更正这个老问题!这是MS的support里Microsoft Knowledge Base Article - 253555 的原文:
FIX: Error Message "Report Width Is Larger Than the Paper Width" on Exporting Data Report
Report width is larger than the paper width.
This error usually occurs when the report you are trying to export is laid out for Landscape orientation printing.
CAUSE
The DataReport designer expects a page size of 8.5 x 11 inches laid out in a Portrait orientation. Exporting the report to a text file or an HTML file in Landscape orientation does not work properly because of this limitation.
RESOLUTION
There is currently no workaround for this problem in releases prior to Visual Studio 6.0 Service Pack 4.
This behavior no longer occurs with the version of the DataReport that ships with the latest service pack for Visual Studio 6.0.
