Hi,

We wide use Bitmap() dw function in the computed fields of our data-driven DWs. The display images can be stored as external files or as internal resources in PBD(s). In special case I want to display a specific image if the given source file is not accessible. For the external files I can check it with FileExists() global function. But how can I check such a case if it is not a valid resource was specified for the function?

Thanks in advance

P.S.:

If you call a global function from the bitmap function you can do more complex calculations including fileexist. Just don't try inline SQL.

Like this:

bitmap(f_determinebitmap)
