The SetTemplateDef method was provided to let you use values/objects inside the next Template/Item call. For instance, let's say you have a date field in your form, and once the user fills it, you want a /NET Frameworks MonthCalendar object to select it. In order to do that you have to call a code like:

With NAVHost1
	.BackgroundColor = 16777215
	.Create "C:\Windows\assembly\GAC_MSIL\System.Windows.Forms\2.0.0.0__b77a5c561934e089\System.Windows.Forms.dll","System.Windows.Forms.MonthCalendar"
	With .Host
		.SetTemplateDef "Dim x"
		.SetTemplateDef #1/1/2001#
		.Template = "MaxSelectionCount = 1;SelectionStart = x"
	End With
End With

This sample defines the variable x  to be 1/1/2001 for the Template call, so the SelectionStart will be set on 1/1/2001.

The call of SetTemplateDef method consists in:

• First call of SetTemplateDef method should be on a form of SetTemplateDef( "Dim variable[,variable,...]"). This defines the name of the variable that follow to be defined.
• Next calls, must be exactly the same as with the number of variables you defined, which will define the variable one by one. For instance, if your first call was SetTemplateDef( "Dim h1,h2,h3"), it means that the next-three calls of SetTemplateDef defines the variable h1, h2 and h3

Once you defined the variables, they will be available for the next calls of Template/Item properties.
