How to write a code for creating line or curve charts in asp..

Classic ASP can not do this. You need to use a third party component, I use one from www.chestysoft.com called CSDrawGraph.dll - It works very well and is very cheap $50 approx

Thanks a lot.. can we write a program for creating line graph.. i got to know how to create bar graphs, but line graphs i am not getting any idea...

IME - You can create a 'whole lot of code' which appears to render, what look like graphs however I use the component I speak about above. For the sake of $50 I had better things to do with my time. I do hear the .net world has tools for this.

Nice work creating bar Graphs in classic ASP. Once again, IME, when a client wants things like horizontal X axis labels, numbers sitting on top of each bar, to control the max and min X and Y axis values etc........ the ones its possible to create yourself done my head in. These components I speak of have all this and much much more built in. Good luck

Ok.. I wanted to send automatic alarms or messages in a intranet based on some expiry dates... can u give me some idea..

.NET does have an entire set of classes devoted to on the fly image generation/manipulation/etc (System.Drawing) and its a fairly straight forward process however, as Matt pointed out, this ability does not exist in Classic. I agree that you would be better off spending the $50 to purchase a third party component and save yourself a great deal of headaches.

In so far as your alerts, you want these to be sent from a web page?
