Couple of things...

Ok guys,
1) Anyone know of the location i add things in the registry to have my icon and my text appear as an option, then run my program with parms when a certain type of file is right clicked in explorer and also set it so when a file type is double clicked it calls my program with certain parms?

2) I want to read from a file, one byte at a time to avoid HUGE variables when reading large files.. i need to open it using the binary access method, so i can read any EOF markers that are located in the file and as such i cannot use simple Do Until EOF()

3) The MSCOMM control doesnt seem to support standard port speeds?

Thanks

2. Read until Loc(FileNumber) = FileLen(FileName)
Haven't tried this before but it might work.

3. The default for mscomm is 9600. Change the settings of the control to change the speed of the port

Ok, i have created the default item for MY file extension, now i want to add to the context menu shown for ALL other file extensions EXCEPT mine, also does anyone know how to put an icon beside the text in the context menu?

hmm.... when you add a key to HKEY_CLASSES_ROOT\*\Shellex\ContextMenuHandler\

you can get it to display at all extensions, but I don't know if you can exclude them...

I think it's possible to add it to every extension except your's but that'll be rediculous because you don't know when a new extension gets added :(

Hi, what format do i put things in under this key?
Thanks
