Request.Form & Arrays

[James Baker]

I'm trying to use Request.Form to gather information in an array and I keep
getting a type mismatch...not sure if it's even possible. Basically, Page 1
posts to Page 2...and Page 1 contains a variable declared as:

Dim mLic(50)

....which is then populated. When I try:

Request.Form("m Lic()") or
Request.Form("m Lic") or
Request.Form("m Lic(50)")

I get a type mismatch every time. Is there a better/right way to do this?

Thanks!

Re: Request.Form & Arrays

How are you sending an "array" via post? Get and Post handle strings
only... you't can pass an array like this and retrieve it via the request
collection.

Re: Request.Form &amp; Arrays

Fair enough...(forgi ve me, I'm trying to learn ASP again). Can a Session
variable handle this? What's the ideal method for "sharing" an array
between pages?

Re: Request.Form &amp; Arrays

Page 1:

dim myArray(1)
myArray(0) = "a"
myArray(1) = "b"
session("myArra y") = myArray

Page 2:

myArray = session("myArra y")
response.write myArray(0)

However, unless this is a complex array, you are likely better off to avoid
session variable and pass a comma-delimited string around. IMHO.

Does this occur in client-side or server-side code?

Re: Request.Form &amp; Arrays

Server side...I realized the error of my ways when trying to "POST" the
array. Now I'm searching for a better approach.

Re: Request.Form &amp; Arrays

Well, I'm toying with the idea of just written out hidden tags/values and
using request.form that way, as opposed to the array. In order to pass a
comma delimited string, I'd have to parse/concatenate the entire array,
right? I'm trying to see the benefit I guess.

No. You can use the Join function to return a delimited string from an
array. You can then response.write the string into a hidden form element.

Re: Request.Form &amp; Arrays

Thanks for your help...I think I'm good to go now. With every passing
moment, I appreciate ASP.NET that much more.
