There could be any number of reasons someone would want to reset a string, which only means putting it back to its original value. If the string is used as a global variable that must default to a certain value, but utilized to temporarily hold a new value that is referenced somewhere else, then you would want to reset it after it is referenced. But, as Cor so eloquently pointed out, the example code is total nonsense. Is this a true representation of the code in question?

Thanks for the sanity check. The
assignment of s = sOriginal seems superfluous because it is superfluous. Don't know if this code was perhaps cut and pasted from inside a for loop? Doesn't matter. It is still superfluous. -- Show quoteHide quoteRegards, -Ron "tomb" wrote: > Ron, > There could be any number of reasons someone would want to reset a > string, which only means putting it back to its original value. > If the string is used as a global variable that must default to a > certain value, but utilized to temporarily hold a new value that is > referenced somewhere else, then you would want to reset it after it is > referenced. > But, as Cor so eloquently pointed out, the example code is total > nonsense.

I suggest to remove 'sOriginal'. -- M S Herfried K. Wagner M V P <URL:http://dotnet.mvps.org/> V B <URL:http://dotnet.mvps.org/dotnet/faqs/> RNEELY wrote:

If the Sub's /original/ declaration were Public Sub SetTheStringToSomething(ByRef OutStr) Then (in VB) it would return a Variant /containing/ a String (and in VB.Net an /Object/ containing a String). Since sOriginal$ is explicitly Typed as a $tring, this may be an attempt to /remove/ the Variant wrapper and get the value back in to a proper String variable. Regards, Phill W.
