In each programming environment, you can use methods and sometimes expressions to access the data and properties of a DataWindow object.
Data
Methods for single items of data
These include GetItemString for data and Describe and Modify for properties. These methods are available in all environments.
DataWindow data expressions
These let you access single items and blocks of data. You can access data in a single column, data in selected rows, and ranges of rows and columns.
Data expressions have a variety of syntaxes depending on the amount of data you want to access.
You can get and set data values using the following syntax:
dwcontrol.Object.Data [ startrownum, startcolnum, endrownum, endcolnum ]
For a list of syntaxes, see Syntaxes for DataWindow data expressions.
Properties
Methods for properties
These are Describe and Modify. These methods are available in all environments.
DataWindow property expressions
These let you get and set the values of properties of the DataWindow definition and of controls contained within the definition, such as columns and text labels.
Property expressions take this form:
dwcontrol.Object.columnname.columnproperty = value
Where to find information
This chapter discusses techniques for accessing data with emphasis on data expressions.
