Return Value
For EntitySets, relationships, and application directories, the value returned is the number associated with the disk file that contains the specified object.
For application documents, the value returned is the number associated with the disk file that contains the application directory in which the application document was created.
Comments
Use $filebrowse to display the File Open common dialog box and select a file.
The value returned by the function depends on the application user’s interaction with the dialog box:
- If the application user activates the Cancel push button, $Null is returned.
- If the application user makes a selection (multiple selections not enabled), the function returns the directory path concatenated with the file name.
- If the application user makes a selection (multiple selections enabled), the function returns the directory path and a list of one or more file names separated by semicolons.
Example
A properly constructed pattern appears as shown below:
‘All files |*.*|ZIM files|*.zim;zim0*’
In the following code fragment, the variable vIconFileSel is assigned the results of the user’s interaction with the File Open dialog box:
let vIconFileSel= $filebrowse ($concat($DBPath, “\Icons”),
“Icon files|*.ico|All files|*.*”,
cFileMustExist + cPathMustExist,
“Icon File Selection”)
