SaveDialog1.InitialDir := 'C:\MyProjects' įS := TFileStream.Create(SaveDialog1. For example: procedure TForm1.Button5Click(Sender: TObject) Or, you can design your own custom file format to suit your particular needs. And there are plenty of documentation and tutorials floating around for them all, so I will omit code examples of them here. Set FileEdit to an edit control that displays the selected file from the file list box, as is commonly done in Open and Save dialog boxes. What is most important is that the structure of the file needs to allow you to differentiate which strings belong to which ListBox.įor instance, you can use a format like INI, XML, JSON, etc, of which there are plenty of useful classes available to work with them, both native to Delphi itself, as well as 3rd party. Which means, you have to first decide which format you want the file to be in, and only then can you code for that format. You will have to get more involved in handling the file I/O in your own code. SaveToFile() overwrites an existing file, and LoadFromFile() loads an entire file as-is, so there is no possibility of storing multiple ListBoxes to a single file with them. An exception is raised when trying to open. Clicking the Open/Save button executes the open/save dialog. When the application runs, the open dialog and save dialog filters are initialized, so that you can open and save.
LoadFromFile ('c:\DelphiLa\Acron02\Acron.dat') Of course, this assumes that you have a text file named Acron.dat in the directory c:\delphila\acron02. You can load the listbow items from a text file with the procedure LoadFromFile, for example: ListBox1.Items. The SaveToFile() and LoadFromFile() methods of TListBox.Items do not support what you are looking for. This example uses a memo box, two buttons, an open dialog, and a save dialog on a form. Loading the Items of a ListBox from a file.
