如何在 Access 表单和报表标题中使用表格中的附件图像？

Question

I have an Access database used by many projects and each project have its logo and information stored in table called company_info_tb .

I stored the logo in Attachment field type; each project can modify its info and logo to be used in its printed reports.

How I can call the project logo to be shown in the headers of Access forms and reports using a Bound Object Frame or another way?

I tried using dlookup in the Control Source of the Bound Object Frame:

Dlookup("LOGO","company_info_tb")

And using LOGO that was shown in mainform, by putting this code in the Control Source:

=forms!main_frm!LOGO

But it doesnt work.

Answer 1

Options:

1. include logo attachment field table in report RecordSource, without a join clause the logo record will associate with each record of data table/query (Cartesian relationship), place bound control only in header section - not appropriate for data entry/edit form because the resulting query is not updatable

2. save the logo image externally and store path in text field then use DLookup expression or Cartesian query

3. subform/subreport in header

Recommend using Image control and set its ControlSource property either by binding to attachment field or text field or expression to construct external path. A BoundObjectFrame control must be bound to an OLEObject field and options 1 or 3 would work.
