Devc++ to Visual c++ codes not working ??

// Clear TAG
cleartag()
{
#define MSNMusicString L"\\0Music\\0%d\\0%s\\0%s\\0%s\\0%s\\0%s\\0"
#define MSNFormat L"{0} - {1}"
HWND msnui = NULL;
COPYDATASTRUCT msndata;
CHAR buffer[500];
wsprintfW(buffer, MSNMusicString,0, L"", L"", L"", L"", L"");
msndata.dwData = 0x547;
msndata.lpData = &buffer;
msndata.cbData = (lstrlenW(buffer)*2)+2;
while (msnui = FindWindowEx(NULL, msnui, "MsnMsgrUIManager", NULL))
{
SendMessage(msnui, WM_COPYDATA, (WPARAM)NULL, (LPARAM)&msndata);
}
}

this code is successfully compiled in devc++ but i couldt compile it with visual c++, does any one knows why? it gives tons off error first error given in HWND line

[Joel]

Are you sure this is correct:

PHP Code:

msnui = FindWindowEx(NULL, msnui, "MsnMsgrUIManager", NULL) 


[DrO]

and those errors would be...? without knowing the error you can't really expect an answer since that code looks ok from what i can tell. did you make sure you included all relevant header files, etc

error is like that.. i can compile the same project with dev-c++, but i want to use resource files so that i click new dynamic dll on visual c++ 6.0 and then i add my header and c file, but when i try to compile it, it gives this error

note: my headers #include <windows.h>
#include "myim.h"

[Joel]

Try this:

PHP Code:

HWND msnui;
//...
msnui = NULL;

i am too stupid, i find the error my source code name is myim.c not myim.cpp :P thanks for your helps

[mydiz]

when i changed the source file's extension .c to cpp my code is working but winamp couldnt recognize the plugin, does any one have suggestion?

Hard to say without seeing your code...

[mydiz]

i search in the form and i learn that i had to put extern "C", i have another question is there any way to make smaller files.. same code when i compile with dev-c++ it become 21 kb, when i compile the same code with visual c++ 2005 code size become 40 kb, how can i reduce the file size?

well there are some things you can do to decrease filesize...I've attached AggressiveOptimize.h. read the instructions...though VC++ usually gives larger files...that's the price you pay

hehehe thanks alot, my dll now 10.5 kb :P

Np

Btw I see you're running Visual Studio 2005. I tried it but found it so damn slow...took like several minutes to compile anything...and everything is deprecated (eh...dunno spelling) and thus gives warnings. So, nah I didn't like it. But you do?

[Joel]

I use Libctiny.lib.... google-it

[mydiz]

i prefer visual studio for resource editing :P after that i compile it with dev-c++ :P much better and small file size i am a newbie in visual c++ enviroment.. i am a student and i am just geting ansi c++ lesson, my coding is hobby and improving my knowledge.. at that why i dont have lots of lines to compile but one day there will be i guess (sorry for my bad english)

[mydiz]

vs2005 optimized plugins couldnt detected by winamp in some computers does any one have idea about that? libtiny wanted libc.lib.. in visual studio 2005

[Joel]

Libctiny, void some crt... basically I use Multithreaded DLL, with it... maybe you need to add some old and fusy msvcrt.lib

[DrO]

most likely vs2005 is linking to the newer msvc dlls (msvcr71.dll) which isn't a default on most OSes.

check out the dll dependancies of your compiled plugin with this

[mydiz]

i send the compiled dll files.. they have the same code and nearly same resource.. can u check them for me and give me some suggestions?

Multithreaded DLL -> when i select that winamp doesnt detect the plugin, i use Multithreaded. and i add "msvcrt.lib" tothe additional libraries and a friend of mine test it.. it is 9.5 kb.. and it is working in his computer now.. i will check it with a win98 computer tomorrow (being a newbie is really a hardthing )

[DrO]

GEN_IM(NOT WORKING ON SOME COMPUTERS OPTIMIZED VS2005).DLL - missing MSVCR80.DLL which is why that's failing. when you distribute the plugin you'd either need to bundle that dll with it and install it into the root winamp folder or you build the plugin dll statically (which would up the dll size but it'll work on any system that way).

the other two builds check out fine on the dll dependancy count.

[Joel]

But that would be increasing installation size
I like Visual Studio 6.0, because the compiler is so dump <- that we can change its behaviour

Although, you still needing msvcrt.dll (which comes BTW since Win95 OS2)

[DrO]

true but that's what happens when using the crt/any related functions to it. this is another reason i won't mess around with msvc above v6.

with the msvcrt.dll, it's safe to assume that it'll be present in all cases since if that's not present you're unlikely even to have winamp let alone the rest of windows working correctly

Is easier to create your own src code for those functions, like killing lstrlen, lstrcpy, etc...

[DrO]

true, which is what i do for atoi, strnicmp, etc

[mydiz]

newbie solution i finish coding and i compile my dll file with dev-c++ :P would u like to check my newbie plugin? all config files are working.. maybe coding own strlen function is better for msvcrt

[mydiz]

i forgot to attach my file, it can swap title-song name, have show on pause feauture and dont show video files titles on msn, sometimes its not good to see video files by others especially when i forgot nowplaying open in msn

vc2005 uses alot more than just msvcr80.dll even tho depeneds.exe says thats all it needs.

vc2005 creates WinSxS bianrys (not totaly sure what it means, but its something to do with x86 binarys working on x86, x86_64, and itanium versions of windows, without having to use the slow assed emulation layer).

most people who keep fully upto date on windows xp updates (sp2 and everything after it) should already have WinSxS dll's. for those who dont click here for the installer for the package to install most of them (all the needed ones)
