I wrote a program, for example, ABC. EXE, with ABC. EXE generates a binary mydefine. Lob1 (your custom extensions lob1), I want to do is
1. The double-click mydefine. Lob1, the computer will use the EXE open this file
2. Open the ABC. EXE program. Read the mydefine lob1 content,
I know that the first step in to the registry can realize
But the second step is how to open the application reads mydefine. Lob1 content?
