Double click then load my prog

Blitz3D Forums/Blitz3D Beginners Area/Double click then load my prog

no, I don't want to do .bb files
I have my own file type. I have an editor for it.
I have to run the editor then, load the file.
If I double click on "my file". XP then tells me
that it isn't associated with any program. I chooose "my program". It then goes to load and closes out. I want "my program"to stay open with "my file" ready to edit.
