How do you copy one of the values in a structure to another structure..

I know about duplicate(), but wanted to ask if there is a way to just copy 1 value from the structure...

My first thought woudl be to copy it to local variable scope, and the move it into structure I want???

Please let me know if possible.

Thanks

Hi Westside2004,

The following code shows how this function copies a structure that contains a string field, a number field, and a two-dimensional array at the top level:

<cfoutput>
   <cfset assignedCopy = StructNew()>
  <cfset assignedCopy.string = #struct.string#>
   <cfset assignedCopy.number = #struct.number#>
   <cfset assignedCopy.array = ArrayNew(2)>
   <cfset assignedCopy.array[1][1] = #struct.array[1][1]#>
   <cfset assignedCopy.array[1][2] = #sruct.array[1][2]#>
</cfoutput>

The following code shows how StructCopy copies a nested structure:

<cfoutput>
  <cfset assignedCopy.nestedStruct = struct.nestedStruct>
</cfoutput>

To copy a structure entirely by value, use Duplicate.

I just need to copy one value from within the structure ideally..

The structure holds a bunch of other info, but I just want one specific key/value pair...

Can that be done?

Thanks

Hi Westside2004,

i think so we can do it.
<CFSET structone.var = structtwo.var2>
I do not see any problem with that.
