The FileOpenDialog component is used to organize the open file dialog box.
Various component properties can be used to determine which files can be selected in the dialog box. To initialize the dialog box, call the Execute method in the code. After selecting the folder and clicking the Save button the file is available in the FileName property. If more than one file is selected, the selected collection is available in the FileNames property.
After all dialog box parameters have been set, you can view results of the work without having to compile the main form. To do this, select the Check option in the context menu in the file open dialog box.
