## Getting Image Size

function GetBytes(flnm, offset, bytes)
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFTemp = objFSO.GetFile(flnm)
lngSize = objFTemp.Size
set objFTemp = nothing

Set objTextStream = objFSO.OpenTextFile(flnm,1)
objTextStream.Close
set objTextStream = nothing
set objFSO = nothing
end function

function lngConvert(strTemp)
lngConvert = clng(asc(left(strTemp, 1)) + ((asc(right(strTemp, 1)) * 256)))
end function
function lngConvert2(strTemp)
lngConvert2 = clng(asc(right(strTemp, 1)) + ((asc(left(strTemp, 1)) * 256)))
end function

function gfxSpex(flnm, width, height)
fileT=split(flnm,".")
if fileT(1)="gif" then
Width = lngConvert(GetBytes(flnm, 7, 2))
Height = lngConvert(GetBytes(flnm, 9, 2))
elseif fileT(1)="bmp" then
Width = lngConvert(GetBytes(flnm, 19, 2))
Height = lngConvert(GetBytes(flnm, 23, 2))
elseif fileT(1)="png" then
Width = lngConvert2(GetBytes(flnm, 19, 2))
Height = lngConvert2(GetBytes(flnm, 23, 2))
end if
gfxSpex=true
end function

if gfxSpex("images/urlogo.gif", w, h) = true then
response.write w & " x " & h
end if

Which is a little bit shorter, and seems to work ok so far, but isn't there anything easier, like php's "getimagesize(\$imgFile);"?

## Asp Get Image Size

i have a page that displays an image. the image path is a variable passed in the url link. eg. enlarge.asp?picture=http://www.hey/.com/you.jpg
and the window it opens works. but id like to try and get the enlarge as to get the height and width dimentions so i can call a new window to opena popup and ill dynamically have the images dimentions to scale the popup to fit.
and right after the javascript calls a new popup window itll use a close window function. and since it happens before the head tags it should be seamless as if i had a regular link calling a popup.

## How To Get The Size Of A Jpeg Image ?

How can I get the height and width of a jpeg image?

is it possible to have an asp script create a thumbnail of an image upon upload?

i want to create a rather small thumbnail and 65 x 83 and put it in a folder '/sized'

oh yeah, and one more quick thing.. i am pulling information from a database.. why is it that the symbol ' gets changed to a ? when pulling it from the field.. will this go away when i start adding information through forms instead of access?

## Displaying Image At A % Of It's Size

The pic in the DB is just a named reference, as all the pics are stored in 2 common folders. 1 for the normal size pics and 1 for the thumbnail equivalents.

As this particular page has to be tight on space, I wanted to set the image as a percentage of it's size so I set the following:

<IMG SRC="thumbs/<%=picname%>' WIDTH="30%" HEIGHT=30%> etc....

Problem I have with this is that the browser seems to set all pics to 1 common percentage size rather than each being say 30% of each individual pic's size. This results in some piccies being completely distorted.

I don't want to go down the route of storing the x and y of each pic in the DB, so could you please let me know if I am doing something really stupid with the above.

## Image Type And Size

My ASP app dynamically retrieves from db and sends JPG images using Response.BinaryWrite(). And it seems work. The script sets image type as "Response.ContentType = 'image/JPEG';"

How to set these properties properly?

## Reduce Image Size

Is there any routine I can call to reduce the size of an image file after
uploading a file from a client. I am looking to reduce file sizes
programmatically using C# in my web page after uploading. I know that
Photoshop can do it but I need to do it dynamically in my web page. I tried
doing it myself with some of the Bitmap thumbnail instructions but the
resulting image is very bad. I need a file reduction routine that creates a
good image that is smaller. I figured if Photoshop can do it then so can I
but how?

## Calculate Max Value Of Y Axis

I am using a javascript function to draw a graph on my page, which all works fine. One of the parameters that I pass to the javascript function is the maximum value of the x and y axes.

I have encountered a problem, in that if I hardcode the maximum value of the y axis to 1000, and the maximum value that I am plotting is very low, eg 10, the bar is so small it can hardly be seen. It would be better in this case if the maximum y value was something like 15 to ensure that the bar went almost to the top of the grid.

The code which is doing the count is a simple loop which is looping through each of the months in the financial year counting the number of meetins which have occured in each month. Code:

## Calculate Percentage

Our store software currently displays the total amount saved (the list price minus our price) for every product using the code below:

'Calculate "YouSave"
If Product_ListPrice > 0 Then
Product_YouSave = Product_ListPrice - Product_LowestPrice
End If

I, however, would like to also diplay the percentage saved next to the amount saved. I tried using the code below but it won't work. Can someone help me out?

'Calculate "YouSavePercent"
If Product_ListPrice > 0 Then
Product_YouSavePercent = ((1 - (Product_LowestPrice / Product_ListPrice) * 100)
End If

## Automatically Calculate

I am building a database that users will update.
I have a table named "products".
Every product has a shelf life of 3 years and expires exactely at the end of the 3rd year.
Here is my table:
Productid ---- int
productName ---- varchar
manufacture_date ----- datetime default (getdate)
Expire_date ----- datetime

What I want is this, whenever a product is entered, the defualt date is the date the entry
was made. (I am using the "getdate") to automatically grab this.
BUT I also want the "Expire_date" field automatically calculated and then filled in.
That is, a user enters a product "manufacture_date" as 05/22/2003,
Then I want the expire field to be filled with 05/22/2006.
My preference is to handle this on the DB site and not ASP.

## Calculate Values

How to take values from a query and add them together to get totals.The current setup I have:

User selects home they want and clicks on link that passes variable (model home #) that takes them to page 2.

Value in query string is taken and used to bring information about home such as base price amongst other things.

What I would like to do is start with home base price and then call upon options stored in database(each option has their own price)and user can go down a list and select the options(via checkboxes)they want and then at bottom they have a total button that totals base price of home and each option they chose.

Size, Material Grade, Module and Weight.

I wanted to be able to give the user the ability to calculate the
sum of weight according to a specific material grade and specific size in a specific module.
