After you have written several XMod applications, it seems you look for better ways to make your XMod code library more reusable.

Here is a tip on using parameters.

There are certain values that most forms have in common. Instead of entering these values throughout your code, use parameters.

Here is an example:

You begin by adding parameters to your form.

<parameters>
     <parameter name="iDir" alias="imageDir" default="LinkImages/"></parameter>
     <parameter name="dURL" alias="domainURL" default="http://yourdomain.com"></parameter>
     <parameter name="sEmail" alias="SiteEmail" default="someone@yourdomain.com"></parameter>
     <parameter name="smtpServ" alias="smtpMailServer" default="mail.yourdomain.com"></parameter>
     <parameter name="sSubject" alias="EmailSubject" default="Your Directory Listing"></parameter>
      <parameter name="redir" alias="RedirectUrl" default="Your redirect URL"></parameter>
</parameters>

By using parameters, if you have a certain chunk of code that you want to reuse on another form, you can simply grab a section like this:

<email target="{ContactEmail}" from="{SiteEmail}" subject="{EmailSubject}" smtpserver="{smtpMailServer}" sendrule="add">

or

<redirect target="{RedirectUrl}" />

Here is another example of passing values to a form:

By placing parameters in the called form, you can then accept values that are passed from a template.

<parameters>
    <parameter name="CName" alias="CName" default=""></parameter>
    <parameter name="CCode" alias="CCode" default=""></parameter>
    <parameter name="VEID" alias="VEID" default=""></parameter>
    <parameter name="VID" alias="VID" default=""></parameter>
    <parameter name="LID" alias="LID" default=""></parameter>
</parameters>

The code in a template may look something like this:

a target="_blank" href="/Default.aspx?tabid=1&amp;CName=<xmod:field name="Company"/>&amp;VEID=<xmod:field name="ContactEmail"/>&amp;VID=<xmod:field name="UserID"/>&amp;CCode=<xmod:field name="PromoCode"/>&amp;LID=<xmod:field name="ListingID"/>" target="_blank"

Using parameters to create reusable code will save you a lot of time.
