Code Snippet of the Month
The following function demonstrates one technique for coding a Yes/No dropdown. It uses a for loop which can be expanded to handle more than the 3 states (Y, N, and blank).
Example of calling the function:
Do you fish? <%=YesNoDropDown("ynFish", "")%>
Function YesNoDropDown(strName, strSelected)
Dim i
Dim strSelectedString
Dim YesNoName
Dim YesNoCode
YesNoName = Array("Yes","No")
YesNoCode = Array("Y","N")
YesNoDropDown = "<select name='" & strName & "'>" & vbcrlf
YesNoDropDown = YesNoDropDown & "<option>" & "--" & "</option>"
For i = 0 To UBound(YesNoName)
If strSelected = YesNoCode(i) Then
strSelectedString = "Selected"
Else
strSelectedString = ""
End If
YesNoDropDown = YesNoDropDown & "<option value='" & YesNoCode(i) & "' " & _
strSelectedString & " >" & YesNoName(i) & "</option>" & vbcrlf
Next
YesNoDropDown = YesNoDropDown & "</select>" & vbcrlf
End Function

Cannot use generic Request collection
/_private/footer_content.inc, line 72
Cannot use the generic Request collection after calling BinaryRead.
Explanation: Although you can use the generic request collection, as in Request("SomeValue"), for either Request.Form("SomeValue") or Request.QueryString("SomeValue"), it's best to avoid the generic request collection until it's really needed. The generic request collection causes problems in some circumstances. For example, you cannot call the generic request collection after a BinaryRead.

Resource Link of the Month: VBScript Language Reference on Microsoft.com
The best resource for quickly looking up ASP Classic commands. Even better than having a reference book. Language Details Topic:
Question: What is the syntax in ASP Classic for using an associative array?
Answer: Use a dictionary:
Dim StateList
set StateList = Server.CreateObject("Scripting.Dictionary")
StateList.Add "CA", "California"
Response.Write "NV is " & StateList("NV")For more examples, refer to our ASP Classic Associative Array (Scripting.Dictionary) article.

Tip of the Month
Although you can use the generic request collection, as in Request("SomeValue"), for either Request.Form("SomeValue") or Request.QueryString("SomeValue"), it's best to avoid the generic request collection until it's really needed. Use a For Each loop to loop through elements. |
