FWIW - when following exactly the recipe you provided, mine worked OK. Three small changes though:
You had this in your VB form: Private Declare Function doit Lib "bar.dll" (ByVal ... However, since the function's name in MyTest.c is testit (not doit), I added Alias "testit", like: Private Declare Function doit Lib "bar.dll" Alias "testit" (ByVal ... Second: your script builds "MyTest.dll", not "bar.dll", so I changed again: Private Declare Function doit Lib "MyTest.dll" Alias "testit" (ByVal ... Third - you called your test function from within Form_Load. This will only (normally) run once for any particular form. So, I added a button to your form, and moved "i = doit(100)" into the new Button1_Click function. Works perfectly for me... You might try compiling to an .EXE and running that, instead of running inside the VB debugger... --Kevin -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
