I do not know whether this is possible or not but

We have a requirement to open an exe (My VB 2005 windows application on a local user's machine) through heyperlink in an email passing a parameter tothat exe)

I can create an HTML email with a link to my exe but not sure how can you pass a parameter to that exe?

<a href="file://C:/Myapppath/myexe.exe parameter1">Click to open this application</a>

what do you want to do ?Do you want to do some email bomb just like a

Honestly, I was trying to explore whether that could be possible or not. You are right it can be a huge security problem.

I apologize for such question.
