I know that it's considered sloppy programming to declare a variable on a page if you aren't going to use it, but what happens if you do it? Does it end up costing more bandwidth the more variables that are declared or is it just that it's sloppy to do so? The reason that I ask is because I want to keep track of all of my variables on one common page instead of declaring them on each individual page. This will help me keep track of what variables I have on my site and what they are being used for. But if I do this all of the variables will be declared at once, even when they aren't needed. What are the consequences of this going to be? ------------- http://www.AnswerPlanet.info is coming soon. |

I think it is going to use bandwidth becuase bandwidth is calulated by file size, and when you open the file, it goes through the entire code and checks it out. So any extra declarations or anything in the file which increases it's file size will cost a lil bandwidth(depending on how much the extra declarations add up to in filesize.) lol. *takes breath*

Good point. I got to thinking about a different way that I could do it. I still want to declare all of my variables on one page but if I have a variable like this on every page:
Then on the variables page use
That may cut down on the bandwidth because I don't think it will read the portions of the variables that do not meet the If criteria. I know it sounds strange what I want to do, but I've done a lot of customization and am finding it difficult to keep track of all of my variables. This was the best way that I could think of to start organizing. ------------- http://www.AnswerPlanet.info is coming soon. |

except when an asp page is processed the file size does not determine the bandwidth used, the file output does. so declaring a useless variable would only use up memory on the server while the processing of the page is running (since all accumulated memory is released at termination of the processing) for example, this page would have a relatively small file size, but would consume a hell of a lot of bandwidth (and cpu cycles)... Dim myVar not only would that send millions of lines to the remote user, but would eventually kill your computer, causing it to use all it's memory...

Just a simple For i = 1 To 1000000 Response.Write("Hello" & vbCrlf) Next Will killl your server |

Yikes, and if I'm on a shared server that would really cause problems. Point well taken. ------------- http://www.AnswerPlanet.info is coming soon. |
