WR OPEN DOCUMENT (area; document{; type})
| Parameter | Type | Description | |
| area | Longint |  | 4D Write area |
| document | String | | Path of document to open |
 | Path of the open document | ||
| type | String | | Type of the document to open (4 characters) |
| Type of the open document (4 characters) |
Description
The WR OPEN DOCUMENT command opens the document specified by document and places it in the 4D Write area referenced by area.
document is the name or the complete access path of the document file.
Examples:
• On Windows, you must include the "\" character between directories:
"D:\directory1\directory2\file.4W7".
• On Mac OS, you must include the ":" character between folders:
"MacintoshHD:Folder:Document".
If the document does not have an extension (Macintosh document), 4D Write will try whatever is best to open it.
If document contains only the name of the file, WR OPEN DOCUMENT will look for the document in the folder of the database's structure file.
If document is an empty string, WR OPEN DOCUMENT displays the standard Open file dialog box.
When the Open button of the Open file dialog box is clicked, the OK system variable is set to 1, and the document variable will be assigned the complete access path of the file the user selects.
If the user clicks the Cancel button, document returns an empty string and the OK system variable is set to 0.
The optional type parameter allows you to filter the document types displayed by default in the standard Open file dialog box— except for HTML documents. For HTML documents, the type parameter is used for displaying either the HTML source code (if type "TEXT" is passed) or the HTML page (if type contains "HTML" or is omitted).
In all cases, after the command is executed, the type variable returns the type of the actual open document.
The file formats supported by this command are:
| Type | Files |
| 4WR7 | 4D Write |
| 4WR6 | 4D Write version 6.0 |
| 4WT7 | Template 4D Write |
| RTF | RTF file |
| DOC6 | Word document |
| ASCW | Windows text file |
| ASCM | Mac OS text file |
| ASCU | Unicode text file |
| HTML | HTML text file |
Example
The following example opens a file located in the database's directory.
