Hyperlink to local executable

Hi there,
Can anyone out there help with the following?
I have a list of documents that appear in a table for a user. The documents are imported from a database and an example is as follows:
Displayed:-----------------------------Field property:

Introuctory email to Client ----------/docs/1.msg

Initial document to Client------------/docs/2.doc

Update document to client-----------/docs/3.doc

Update email to 3rd party-----------/docs/4.msg
etc
The documents and emails could vary.
What I need is a hyperlink that links to an executable file followed by the relevant document so that nothing is downloaded to the user pc.
For example, for email 1.msg it would point to "/docs/emailview.exe 1.msg"
This is what i've tried:

1. Setting the database field value to "emailview.exe 1.msg"
   
   Result - doesn't work. Crashed because of the space between the exe and 1
   
2. Pointing to the exectuable
   
   Result: Launches the EXE but not the relevant msg
   
3. Pointing to the MSG file
   
   Open the MSG on the local pc (with Outlook). Not ideal. The EMAILVIEW program just gives them a view of the email without importing it to outlook.
   Any ideas would be much appreciated.
