Add Image To Crystal Report At Runtime

问题

I would like to add an image to a crystal report at runtime.

I am currently doing this using a second data table containing only a byte field and then a blob field on the report. However this feels like a hack and if there is no data in the first primary table then for some reason the image does not show.

Is it possible to add an image with code or another method?

I'm using crystal reports for visual studio 2010. Winforms project. Either C# or VB.

回答1:

If you want to store the logo on disk instead of in the database:

1. In Designer, insert a placeholder image.
2. Right-click the placeholder image, and click Format Graphic. On the Picture tab, next to Graphic Location, click the formula button. Enter the path there, or provide a formula which provides it.

At runtime, Crystal will substitute the image from the file.

If you want, you can use a parameter field in your formula. That way you can provide the path programmatically at runtime.
