fortran dll from VB and msdos "debugging"window

[mauri72]

Hi there, my research group has traditionally been working with lahey f90 fortran compiler, which in my humble opinion is the worst compiler I had the misfortune to work with, but it had a "nifty" feature (at least for our purpose).

During compilation of the fortran dll I could specify a -win flag, whichallowed meto use print statements in the fortran code, for example to print values of certain variables on a msdos screen in the backgroundduring the execution of the DLL from the visual basic main part of the program. This made much simpler our debugging process.

Now I have managed converting our dll so that compaq visual fortran compiles it correctly and the vb code runs smoothly with it....but is there any way i could get that msdos window (or something similar)back?

Thanks in advancefor your help

USE DFWIN

i = AllocConsole() !Creates a console

!Your code with print * here

i = FreeConsole() !Destroys the console

hey thanks a lot!! :)

and thanks to the console window I found out that the values of the variables passed by VB to the DLL do not match with the same DLL created with lahey....bummer...back to the drawing board!!
