Hi all,
I'm trying to create a report that displays all relevant information per record. However this includes displaying a screenshot for each record.
Images are uploaded and stored as BLOBS. I've used this method as many discussions say it is the best option, due to bloating and path issues with the other methods. However to write the code for this myself is a little outside my knowledge, so I've had to use some found on the internet and alter it accordingly.
Everything regarding uploading the file to the database is working, but my problem now is getting to files to display in a report. I've tried using everything from object frames to activeX image controls, but I fear I do not know enough about what I'm doing here to make use of them correctly. Can anyone please offer any help on how to display BLOB images in reports?
Thanks.
Adam.

Recognized Expert Expert @Adam - There also exists a 'DAO based' approach to writing Binary, BLOB Data to a Disk File. I'm not sure how it compares to the ADODB approach, but it may/may not be faster and more efficient. If you like, I'll Demo it for you, just let me know.
Sorry to bump an old thread, but I had one final question around this topic:
Regarding the temp folder that gets created for the blob files - if the database was split, with a front end on each user's machine instead of a network, would the temp folder be created in the location of the front end, or the location of the back end?
Only reason I ask is it would seem sensible if the folder was deleted once the database is closed - if it's created in the front end location then doing this shouldn't cause conflict if one user was accessing it while the other person deleted it, as they'll each have their own temp folders to use for generating pictures in the reports.

To the best of my knowledge, the TEMP Directory would be created on the Front End, unless specifically directed otherwise, via an Absolute PATH.
Ok thanks Adezii. I'll have to play around with it when I fix everything else! :)

I am trying to insert a .gif. file into an Access report - using
Insert Picture.
The original image is 8X11, but access changes the size to 4X6.5.
When I change the size of the image in access is puts white border
around it and does not change the actual image.
Is there a setting I need to change that would allow access to import
at the correct size, or do I need to use another file type besides

I have programatically saved a picture to a table as Blob format i.e long binary format. When I linked the field to a access report, it does not print. I tried using a third partysoftware like DBPix and embedded it into the report, but it says the picture is too small.
Is there any way to save a picture progmatically and display it on the report
