Load Image via Code

rbuser

hello,

When loading an image by RAP, if it does not exist shows an exception.

I would treat this by placing before the load if a filexists (....

I could not, is it possible?

Hi Gustavo,

RAP does not have the FileExists routine built in however it would be
very easy to create a pass-thru function that does so. Take a look at
the main RAP demo located in the \Demos\0. RAP\... directory for
examples of how to create and use pass-thru functions.

The TppDBImage can optionally be connected to a string field that contains
an image file name. It will internally check whether the file exists and
load the image.

I don't know whether this would be an option for you, but thought I would
mention it.

Can that be achieved via the editor or do you need Delphi code?

This would be a useful function for our end users - is there any
documentation anywhere?

You just need to set the DBImage DataPipeline and DataField properties to
bind to a datafield of type string.

The RBuilder help topic for TppDBImage needs to be updated - this will be
included in the next maintenance release.
