Hi! i want to use directinput, but it doesn''t seem to work. everytime i call ''directinputcreate'' the compiler gives me a linker error: unresolved external ''directinputcreatea'' referenced from blablabla i really wonder why this message shows up. it only shows up on the ''directinputcreate'' and ''directinputcreateex''. how would the code look if i used cocreateinstance? Thanks!

It is easy:

YOu have to include the "dinput.h"!!!
And there are also 2 LIBS:

dxguid.lib
dinput.lib

if you link these 2 lib it should work!!!

Yes, I included the header and the libs, but it doesn''t work. I already implemented DirectDraw and it works fine...

That''s the problem I''m having. When I first wrote the DirectDraw routine. I included the ''ddraw.h'', the ''ddraw.lib'' and the ''dxguid.lib''. I wrote the routines in a dxdraw.cpp

Then I started working on the DirectInput routines. I started the same way as with ddraw, but...

Well, at least DirectDraw works fine, it might be a bad lib (DirectInput), though I don''t think that''s the problem. I''ve been fuzzing around with that problem for a couple of hours, but it still doesn''t work. Quite strange...

Try using the ''directinputcreateex'' instead of directinputcreate

Saisoft - I also tried that one. The error showed up anyway. I will keep on looking.

Thanks anyway!

I have never done any directx programming, but does the directinputcreate function take any structures as parameters and if it does, is there and extended structure that you were using

Saisoft - directinputcreate does take some parameters, but that''s not the point. you see, I''ve come to the point where I typed in the example in the SDK and it still won''t work.

furby - I use BCB5.0 Enterprise Edition and yes, I use the Borland libs (I''ve been checking on that about a thousand times) ;-)

But, I''ve been investigating on that problem: Every time I recompile the whole thing (not only the editet parts) I get the following error:

Error processing module

It''s another linker error, and the bad thing is that it seems to be the dinput.lib...

Now, when I recompile only the editet parts I get the ''unresolved external...'' (see above).

I just don''t get it. :-(

Ah, the wonders of DInput.lib. The Microsoft version AND the new ''borland'' version libs have a error in them that makes BCB - VERSION 5 ONLY!! - complain of an ''error processing module''. What you must do, is to implib DInput.dll, then dump the cdfi_*** constants into a file for reading. I struggled with this problem before, luckily I had version 3 that allowed me to access the M$ version of Dinput.lib and dump the data. I can give you it if you like w/ the function to read it. And, an implib''ed dinput.lib, so everything will work.

C++ freak - It would be way cool if you could send me those files! Finally I have an answer to my question! Thanks!!

run Implib to make an import library of dinput.dll in c:\windows\system. Then put this library with all your other libs and delete your old one. Unfortunately you will no longer have c_dfDIKeyboard and the rest so you will need to link in dxextra.lib which is in your main lib directory.


Please state the nature of the debugging emergency.

I have made a Direct Input Tutorial --->

at : "www.jankeytec.com"

At the Basics Section: Sorry but it is German (I am an Austrian)



perhaps there is an Error with DDraw --> Write A Programm "only" with DInput. If it doesnt owrk: I dont know!

Why would anything happen to your 2D code if you don''t use anything new?

Thanks,

Sometimes I think I know what I really don''t, but then again usually I do know what I don''t, but just don''t realize it, maybe its because I am so young, but then again it could be because I am insane.
