If i have printf("something"); in my DLL how do i make it appear to the screen?
Ideally I would like the execution screen to appear, i would watch the printf's, then dissappear once th execution is finished.
as of now i never see the execution screen
im using MSVC6
thanks for your help... this board is amazing.
The printf function cannot be the dll. It should be in the stdio.h.
Did you mean a different function such as user defined function which is named other than printf in the dll, which need to access in your main?

i have a function that does a bunch of stuff but print to the screen during the execution of my dll.
I want to see those prints to screen.
right now i cant see my dll executing at all.
Most likely cause your dll doesn't have a console associated with it. Just because you are calling your dll from your code doesn't mean it has your console with it.
Set the DLL's stdout and stdin handles (ie inherit them when you init the dll), to whatever and read it via a pipe. See MSDN
My guess is that you are using a DLL as part of a windows applicaiton, so there's no console attached to the application - is this correct? If so, you've got two choices:
- replace printf's with fprintf's (and open a log-file at DLL init, close at DLL exit)
- use AllocConsole() to create a console window (this does all the magic necessary to get printf working)
For many things, the first approach is probably better than the second, as you get a permanent result. But if you want to see the progress for example, then the console window is a workable solution (but using a windows style progress is probably better).

hmmm.. the AllocConsole() is exactly what i want but it doesnt seem to work
it brings up a console but it doesnt seem to write to it.
my program is like this:
there is nothing in the console just a black screen.Code:AllocConsole();
Printf("blh blh");
FreeConsole();
