Customizing the converter in Java

Painting Code 39 Extended in Java Customizing the converter

Now, this is one fine service as is But you can customize it, too XEcom will change practically anything about the currency converter for a fee, but the company has also built plenty of options into it that you can use on your own

If you know the country from which most of your foreign customers come, you may want to set the converter so it s ready to convert from your customers currency to yours right away Say, for example, that you re in the United States and you know that almost every one of your overseas customers is from the United Kingdom You d probably do well to set the conversion to default values of dollars to pounds in that case This won t prevent anyone from another country from using the converter in the normal way All it does is set which currencies are selected at the start; visitors can still choose other currencies if they want This is what you need to do to set the default currencies in the converter: 1 Go into the HTML source code and find the SELECT elements The one whose name attribute has a value of From is you guessed it the currency to convert from The one whose name attribute has a value of To is the currency to convert to One of the OPTION elements in each has the selected attribute In the original version, the default From currency is the euro, and the default To currency is the US dollar 2 To change the default, just delete the word selected from the OPTION elements for the current currency and add it to the ones you want to use Simple, ain t it

Now, what if you have only one product, or what if all your products are the same price For example, suppose you have a price of USD $4995 that most people will want to convert to some other currency Having already set the From currency to US dollars, you can now set the default amount to 4995 This default makes it really easy on your customers all they have to do is pick their native currency, and they re off and running To set the default amount, look for the following code line near the beginning of the form: <INPUT type= text name= Amount value= 1 SIZE=10><BR> Just change the value of the value attribute To set it to 4995, change the code to this: <INPUT type= text name= Amount value= 4995 SIZE=10><BR> Users can still change the default value to anything they want by simply typing over it, just as they can select different currencies by selecting something other than the default selections

If you want to change the order of the currency choices from alphabetical to some other method such as placing the most likely currencies on the top of the list all you have to do is to cut and paste the OPTION elements that reflect the currency values in the listings Remove them from their current positions and paste them into their new positions That s all there is to it If, for some reason, you don t want to give your users any choice in these things, UCC accommodates your wishes through the use of hidden variables To do this, you add some INPUT type= hidden elements right after the <FORM> tag and just before the <TABLE> tag To set the From currency so it can t be changed, use the following code: <INPUT type= hidden name= From value= xyz > Replace the placeholder xyz with the three-digit code for the currency such as USD for US dollars or GBP for United Kingdom (or Great Britain) pounds To set the To currency, you do the same thing, but the line reads as follows: <INPUT type= hidden name= To value= xyz > To set the value so it can t be altered (which prevents people from using your version of the UCC for test purposes unrelated to your site), add the following line of code: <INPUT type= hidden name= Amount value= xyz > Replace the placeholder xyz with the amount to be converted (for example, 4995)
