Typical Example
TFile = SelectFile()
The ‘File Open’ dialog will be displayed, showing all files in the current working directory. The
users choice will be stored in tFile.
TFile = SelectFile(“Text Files (*.txt)|*.txt||”)
The ‘File Open’ dialog will be displayed, showing just files with a .txt extension in the current
working directory.
TFile = SelectFile(“Text Files (*.txt; * . csv)|*.txt;*.csv||”)
The ‘File Open’ dialog will be displayed, showing files with either a .txt or .csv extension in the
current working directory.

files), and one to show document files (just .doc files).
TFile = SelectFile(“”, “C:\WINDOWS”)
The ‘File Open’ dialog will be displayed, showing all files in the “C:\WINDOWS” directory.
