[comp.windows.ms.programmer] DLL creates invisible program...help!

g-man@flowzone.EBay.Sun.COM (Luis Navarro) (03/11/91)

I have been working on a windows program that communicates with a MIDI
interface via IRQ2 where all the main code is in C and the interrupt
handler related stuff is in assembly.  It was suggested that I stick
all the assembly code in a DLL, which I did.  However, when I run the
program now (in any mode) it runs "invisibly"--no application appears, 
although further attempts to run it bring up a message saying that an
instance is already running and that I cannot run another (I specified
a FIXED SINGLE code segment in the .DEF file).  Anyway, this application
also does not appear in Task Manager.

I have been fighting this thing all weekend and cannot seem to get my
previously working application back up.  Does anyone out there in netland
have any ideas as to what went wrong and/or where I should look in my code
for problems?

Thanks in advance,
