UserDataSet and Graphics

ic70

I am trying to use a TfrxUserDataSet to feed my Report.
The report is able to obtain values of text fields, but I am unable to get the report to read Graphics fields.
The problem is that even though a Graphic on the report is set to the correct DataSet and DataField, it never queries the UserDataSet for the Graphics field! [img]style_emoticons/<#EMO_DIR#>/blink.gif" style="vertical-align:middle" emoid=":blink:" border="0" alt="blink.gif" /> I am using FastReport 4.5. Thanks![/img]

IIRC the user dataset does not read the blob you will need to use the obp event of the image view
and write a handler to read the blob stream and load the stream into the pictureviews picture property.

Hi Gordk,

I won't start a new thread since my question is similar.
Could you be more specific please?

I have an img in a file. And in my database I have a field for "vectors" (a text array of commands that allow me to recreate the drawing of a user).
I should mix the img and the vectors, and show it on the report.

I can create a TBitmap, but how can I use it in my report? I cannot use blob calculated field [img]style_emoticons/<#EMO_DIR#>/sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> Thank you very much[/img]
