The TemplateResult, TemplateResultN, TemplateResultS property returns the result of the last Template call, as variant, numeric (double) or as string. The Template property takes a string called x-script, and executes it. For instance, you can use the TemplateDef, Template, TemplateResult or ExecuteTemplate to work with x-script. It is known that programming languages such as dBASE Plus, XBasic from AlphaFive, Wonderware, does not support setting a property with multiple parameters. In other words, these programming languages does not support something like Property(Parameters) = Value, so our controls provide an alternative using the TemplateDef method.

For instance, the Wonderware does not support parameters for events, or parameters of any event are not defined during the event, so in this case, you require an alternative in order to get the value for these parameters. Let's say the Select event, which has one parameter ID of long type, which indicates the identifier of the item being selected. The EventParam property gets the value for any parameter of a specified event. The same, the EventParam requires parameters so Wonderware won't support it, in this case, the Template and TemplateResult can be used to get the ID parameter of the Select event as follows:

DIM id As Message
#exMenu1.Template = "EventParam(0)";
id = #exMenu1.TemplateResultS;
MessageBox(id, "Identifier", 0);

This code must be called during the Select event, else the EventParam has no effect.

The Template script (x-script) is composed by lines of instructions. Instructions are separated by "\n\r" ( newline ) characters.

An instruction can be one of the following:

• Dim list of variables Declares the variables. Multiple variables are separated by commas. ( Sample: Dim h, h1, h2 )
• variable = property( list of arguments ) Assigns the result of the property to a variable. The "variable" is the name of a declared variable. The "property" is the property name of the object in the context. The "list or arguments" may include variables or values separated by commas.  ( Sample: h = InsertItem(0,"New Child") )
• property( list of arguments ) = value Changes the property. The value can be a variable, a string, a number, a boolean value or a RGB value.
• method( list of arguments ) Invokes the method. The "list or arguments" may include variables or values separated by commas.
• { Beginning the object's context. The properties or methods called between { and } are related to the last object returned by the property prior to { declaration.
• } Ending the object's context
• object. property( list of arguments ).property( list of arguments ).... The .(dot) character splits the object from its property. For instance, the Columns.Add("Column1").HeaderBackColor = RGB(255,0,0), adds a new column and changes the column's header back color.

The Template supports the following general functions:

• RGB(R,G,B) property retrieves an RGB value, where the R, G, B are byte values that indicates the R G B values for the color being specified. For instance, the following code changes the control's background color to red: BackColor = RGB(255,0,0)
• CreateObject(progID) property creates and retrieves a single uninitialized object of the class associated with a specified program identifier
