Question

Using OLEObject of access programatically

Asked by: tlangent

I created in access a column of type OLEobject in order to store pictures.
From my VB code:
1) How can I create filter to check if the field is null?   (namoOfField <> null does'nt work)
2) Given a path of the image how do I insert it to the column?

Are you using ADO or DAO to connect to the Access Database from your VB program?

Are you applying the NULL filter in an Access Query, or are you issuing a query from your VB program?

Normally, if you are creating the SQL to submit to Access, then the syntax would look like:

SELECT * FROM MYTABLE WHERE MYFIELD IS NOT NULL

If you are typing in the filter in the Query grid in Access, then you should probably just type NOT NULL in the field value column.

This expression will do it (in an Access query):

SELECT tblCategories.CategoryID, tblCategories.CategoryName, tblCategories.Description, tblCategories.Picture
FROM tblCategories
WHERE tblCategories.Picture Is Not Null;
