Open file and wait until the window closes

elwin68

Hello,

A table consists of records with a BLOB field. In the BLOB field a msg file is imported.
A form shows all records and the imported msg file must be shown again.
I added a button with some code behind it. First I export the BLOB field to a temporary file (msg).

Using Hyperlink is a possibility to open the MSG file, but this command doesn't wait until the MSG-window is closed so the temporary file can be deleted afterwards.
In the table Attachment a function ShowAttachment is used for this, but this function asks every time if the temporary file must be deleted. This is not user friendly.

Is there a possibility to open the MSG file in a modal window, so NAV waits until the MSG-window is closed. Afterwards the temporary file can be deleted without a question.

Thanks in advance.
