Topic: How can I edit a dll file - Page: 1

This part of topic is old and might contain outdated or incorrect information

Fist of all I will like to say that VDJ is an excellent and the best dj software out there. This is why I decided to purchase the program.
Anyway, I'm trying to make a dll file for effects but since this is very complicated to do, I need an existing file to visualize how this works. How can I open an existing file? What program do I need to do this?

Your help will be apreciated.

P.S; I have look already in other sections of the forum and also downloaded some examples like .h,.cpp and microsoft visual net but still I cant get it to save as Dll or even open one. Pardon my little programing skills.

Hi and welcome in this amazing community;

You're that's en excellent ... and probably the best PC-DJing software.

Editing a .dll is not the solution (nearly impossible).
You have to program a plugin.
If you have .net, try the Effect SDK: http://www.virtualdj.com/support/developers/effects.html
Can you program in C/C++ ?
 
 
Thanks Clax. I can do little programing if you can say that. I already got to those links you posted. My thinking of a dll file was trying to open it like an XML file in skins which I can do and was able to learn to work with them and I think I can probably make my own skin now(xml with bitmap). But I guess Dll is more complicated than that and either I'm going to have to learn to make them from scratch or I will leave it to the experts.

So you are saying that once a C++ project is saved as an dll it cannot be opened back and be edited?

P.S: All you programers/skinners can do some awesome work. I like the sampler manager, shaker beats and others. TX
 
No a .dll file (dynamic library linker) is a compilated file like an executable file (.exe)
c file (.c and .h) or c++ file (.cpp and .h) => compilator => .dll
 
So with .net you create a new project and choose virtualdj pkugin by using the SKD installed.
Then when treatment is done you create a solution which will be a .dll file.
 
This is going to take some time to get!!!.
I'll work on it and see what results I'll get.

Will post later if I need more help. Thanks for the tips....
 
You're welcome.
 
hi this is cool stuff
 
So please reya_dis, if you like this software... don't crack it!
 
Hey Clax:

Man I have been working on this for long time and still can't get this. My wife is starting to get upset, dedicating too much time to VDJ. Anyway, I believe I'm close to at least reproducing the existing flanger plug-in and that way I will know how this works better.

The problem I'm having is getting a .dll solution. As per previous posts/links, I opened an empty proj. then I saved the .h and .cpp files provided in there and try to compile to create a solution and I get an error message saying I'm missing windows.h files. I'm using Visual C++ 2005 express beta edition (Download trial). Also I tried to download a source code but I guess thats restricted for some users only. I still believe I can do a plug-in if I just get little more direction and help on this.

What ever you can think of that I can use in addition to the other info you already gave me I will apreciate this. For ex: Am I using the right program for C++? If not, where can I get one? Can I get a simple completed source code that I can use to do my .dll and learn from it? I know, this sounds like cheating, but thats the only way I think I can get this. This is the way I learned to work with skins, by editing an existing xml and bitmap file.

Anyway, see what you think and let me know if I got a chance.

P.S: If I could only make at least a simple plug-in!!!

Thanks, again.

well in the .cpp file you write:
#include < windows.h >

in fact windows.h is a library (an include) installed with your compilator (with others file in the same way) so visual c++ 2005 express should have it. I don't understand why
Verify your selected dll with windows standard inluded files or something like that. I didn't test visual c++ 2005 yet but i think soon
 
The "#include < windows.h >" is in the cpp file, But I still get the failed message. Let me look in the visual 2005 folder see if I find anything like you said.
 
In fact i have just noticed the software is not finished so that's the reason why you can't select a dll project directly

Look here to see if your project in visual C++ 2005 express is well:
http://www.virtualdj.com/blog/djcel/?category=2
=> "Project" => "Properties"

Especially verify:
* "Configuration Type: Dynamic Library (.dll)"
* "Use of MFC: Use Standard Windows Libraries"
 
Thanks Djcel for the config setup.

This is what I did: I created a new win32 proj from existing code. Then I pick the destination where vdjdsp2.h and flanger.cpp are located then proj is created, change config setting like what you have and then when I try to build a solution I get this:

1>Compiling...
1>Flanger.cpp
1>.Flanger.cpp(2) : fatal error C1083: Cannot open include file: 'windows.h': No such file or directory
1>Build log was saved at "file://c:Documents and SettingsOwnerDesktopJOSE'S FOLDERflangerBuildLog.htm"
1>flanger4 - 1 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Ok where is the windows.h and math.h in the flanger.cpp file? This is what it can't find.

What the heck I'm doing wrong?

Thanks again
Vnz
 
If possible, can you show me step by step on how to create proj/solution? You can call it Plug-in for Dummies.

Sorry for all the ?'s.
Once I get this I'll be ok.
 
In fact windows.h and math.h are standard windows libraries so they should be with Visual C++ 2005

I have Visual Studio .net 2003 with all the files usefull: windows.h calls others files and so on...

C:\\Program Files\\Microsoft Visual Studio .NET 2003\\Vc7\\PlatformSDK\\Include

These files aren't with visual c++ 2005 beta and i find this beta is not really well: it still lacks a lot of things

install dev-c++ , i's free and this compilator has these files
 
vnz161820:
be sure that you include < windows.h> and not "windows.h" (same for math.h)
 
Ok this is what I did.
Downloaded dev-cpp(Now I got windows.h and math.h), Created empty proj, included vdjdsp2.h and brake.cpp then compile it and I got different errors in different lines.

Djcel: I sent you a prt screen picture of the errors to your MSN e-mail if ok.

See if my proj is set ok. I'm using the files from the effect SDK plug-in page (did not change anything on them).
Do you have something else I can base my 1st proj on.

This is it, If I cant get this in the next day I'm done.

Thanks.

I have the same issue when compilating with Dev-C++ and i don't know why. Maybe the linker editor. I will have a look in the makefile: it doesn't accept or find VdjDsp2.h whereas there is no issue with visual c++ .net 2003
