check attachment name before saving the form

Hi There,

 

Can I check attachment name while attaching?

I want to avoid the Special characters of attachment file name.

Hi @Sachin2 ,

If you are using an Attachment Control, you cannot rename an attachment either while storing it or afterwards. You can however right-click on the file in the Windows dialogue and rename it before selecting for attaching.
You could however reject it if it contained these characters - first make a Collection (screen OnVisible would be a good place (refer this blog of mine using this modified version for another purpose)

ClearCollect(
   colChar,
   ForAll(
      Sequence(13),
      {FieldNo: Char(32 + Value)}
   ),
   {FieldNo: Char(47)},
   ForAll(
      Sequence(7),
      {FieldNo: Char(57 + Value)}
   ),
   ForAll(
      Sequence(4),
      {FieldNo: Char(90 + Value)}
   ),
   ForAll(
      Sequence(4),
      {FieldNo: Char(122 + Value)}
   )
)

Then on the OnAddFile action of the attachment control

ForAll(
   colChar,
   If(
      FieldNo in Last(Self.Attachments).Name,
      Notify(
         "Special Characters not alllowed",
         Error
      );
      Reset(Self)
   )
)

NOTE: This will delete any other unsaved files you have added before this as well.
