Crystal Reports is a professional report design tool with powerful design capability.The designers can create professional-looking reports quickly with it.By studying the push mode,a method to use dataset as the data source of report,and then inject data into data source by push mode is proposed to achieve the purpose of inserting images into Crystal Reports.The data injection process depends on the characteristics of supportting BOLB field in dataset to get the picture content from the medium and store it in a dataset in the byte array form.To insert pictures by this way reduces the coupling between Crystal Reports and data source,is applied to the occasions that data source is scattered and complex,or the occasion that the data needs for further processing after gained.
