Im developing a MDI application in BCB and I wish the user could save his projects as a file with a characteristic extension. Just like WinWord documents have a .doc extension and a BCB project has a .bpr extension.
Then I have two problems.
1) Files with unknown extensions to the system (Id like to use .tcx) get a standard Windows icon. Id like to know how to add my own Icon to the saved file.
2) How can I call my main application and load the data from the file when the user double-clicks the file?
