I have been trying to apply a .txt file extension to my application .since I'm a new to this i had to choose the GUI way so i have already added in my project in File System and Even i have added my extension in File Types as extension .txt and my own icon . even build was successful. now the problem is when i double click to any text file it won load in my application .it just goes blank .but it did open text file via open file which i made in my application . so the question is what did i miss here , how do i open text file just double clicking it ?

thank you in advance

Custom file extension control[^]

You should not use the txt extension since it is already registered and commonly used for text files by many applications. Users expect a text file to open in an application such as notepad, not in some other app.
