Hi RhetTbull? I am new to perling. I am using Active perl to do some excel related stuff later it does some make under cygwin. I am calling cygwin, from a batch file from the actual perl script. I could do everything under Cygwin itself, since win32 modules are not seen to cygwin, I had to do all this. Now, I want it to be working under cygwin, using transparency you are speaking about , could you please let me know, If I can proceed. I am sure, My question is not properly conveyed. Please let me know, just if we can use win32 modules from cygwin, using the transparency you were speakign about with only Active perl installed in my computer?
