Getting Image Size
I only need to know the height and width of the image.

It doesn't seem to be as easy as php's "getimagesize($imgFile);" method.

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

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.

Size Image Upon Upload
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';"

But viewing image properties in IE returns Type and Size as 'Not available'.

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)

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.

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.

How would I go about creating an asp script that will allow me to do so?
There has to be an option in which the user can select from a combo box the module, and then select material grade and size, also from a combobox if possible (getting the data from tblsheets).
