Need help with a clicking button

[11panos04]

It is nice to find you,my english is not my main language,so sometimes i ll run into mistakes etc not intentionally.

So,i have a mini form as my main one with many buttons.One of them when clicked opens a new form.In that form i have reference pics and below each pic another button.Now,what i tried to do is that,since i m completely useless when it comes to coding etc.I made a table with an attachment field, so i can have the attachments bound to the accdb file wherever i take it(not a path to it in my pc).I want,whenever i click a specific button in that form,to open that specific attachment,for example a pdf file.I don t want all the field,but i need i.e. for pic 1-attachment 1, for pic 2-attachment 2 etc. I d like it to be with click on button functionality.If not,clickable pics would work for me as well.

Thanks

Using attachments could cause your db to fill past the maximum, which is why you should store the PATH to the document.
then it can be opened via click.
As an attachment, it is a recordset.
so you must create a recordset to extract another recordset,then open the result.

Can you direct me into doing that?

[ranman256]

paste this code into a module. (Alt-F11, insert , module)
Then it will open ANY file via its extension....
.pdf files will open in acrobat,
.doc files in word
etc

Couldn t do it.Obviously i ve done something wrong.

[11panos04]

Any further help?

"Couldn't do it" means what - error message, wrong result, nothing happens?

If you want to open attachment field item in another application, will have to first extract to a folder location then use Ranman code to open file.

Extracting file from attachment field requires more code. https://accessjitsu.com/2015/10/03/v...ent-data-type/

OP appears to be using 64bit access, so the declarations need to be changed
