This tutorial shows you how to create a "dataset" just like the one in VB.Net
In VB.Net you would create a dataset with "edit" button in an extra column.
Once you click "edit", you get an option to "update", "delete" or "cancel edit mode"
This is just like a cfgrid tag. Although a cfgrid tag lets you bulk insert, bulk update or bulk delete, the dataset object does it one by one. But cfgrid is slower, and may give users Java errors, depending on their browser settings.

This search function is just slightly better than a normal search as it adds the ability to separate two keywords with a + symbol. Lets start with the search form.
I have seen quite a few people looking for prebuilt calendar apps but the people I wrote this for are the people who wanted a headstart in building their OWN custom calendar app.
It is very basic and does nothing more than display the currently selected month/year's calendar and give links to the PREVIOUS the NEXT month's calendars by using The DateAdd() function. Basically the backbone of any calendar app.

If have online store or you are planning to have one; then you must give estimate or real number of shipping charge(I am only talking about FedEx). There are few ways to do this. Like using FedEx ship API writing some script(or using XML injection ) to request rates from FedEx servers. But there is big handicap; FedEx shipAPI is slowing down your application and sometimes their servers are down. Which all doesnt sound good for e-commerce business. This little code is calculating 100% accurately all kind of FedEx services. and there is no handicap because it is running from your server. The only thing you need to is you should call fedex and ask for zone list for your zip code. I have attached database file which is for my location.
