CT OPEN DOCUMENT

version 1

CT OPEN DOCUMENT (area; document{; mode})

The CT OPEN DOCUMENT command opens document and places its contents into area.

If document is an empty string, CT OPEN DOCUMENT displays a standard open-file dialog box, enabling the user to choose the document.

Otherwise, it attempts to open the specified document. If document does not exist, the contents of area remain unchanged and CT Error returns a system error code.

4D Chart expects to find document in the directory that contains the database structure. If you want to open a document outside this directory, specify a complete pathname. See the 4th Dimension Language Reference manual for a brief description of pathnames. If document is already open, CT Error returns a system error.

The optional mode parameter controls how the document is opened. mode is used only when document is not an empty string and is not a 4D Chart document. If mode equals 0 or is not specified, document replaces the contents of area. If mode equals 1, document is combined with the current contents of area.

This example opens a different document based on the value of the Client Type field.
