Hello everyone,

I have never written a DLL before and I thought I would start learning how to write one from the bottom up. Hence, I chose to use FASM.

I have examined the DLL example in the FASM EXAMPLES directory and noticed that it uses the: format PE GUI 4.0 DLL directive. I wondered if anybody could tell me if format PE console 4.0 DLL makes sense?

Thanks!

No, it doesn't make sense. A DLL would be very unlikely to ever (maybe never?) to need a console window.

So what do the CONSOLE and GUI directives do, then?

From Revolution's reply, I gather that the CONSOLE directive creates a console window when the program runs. Does this then mean that the GUI directive might create a GUI?

I don't understand how his might be.

For GUI programs the OS will do nothing.
For CONSOLE programs the OS will create a default console.

Both types can create a GUI if they wish to.

Also both can create additional consoles if they wish to.

Thank you, again, Revolution.

The minimal DLL that I have been attempting to write (using format PE console 4.0 DLL) is not been working. I will change the source to use GUI instead of CONSOLE and see if that works.

The problem which I have been blaming on my mis-application of the CONSOLE directive, has not been fixed by using GUI, instead.

I have started a new thread explaining the error I am getting:
