It is not.  MCI does not support playing anything from resources directly.

Thanks Remy :-)

i will save the mp3 file from resouce and than use the mciSendString...
but only one more thing: What should i do if i want to load the required DLL
"WinMM.dll" via LoadLibrary( ) can u show me how to call the DLL-Entry address...?

What about it?  What exactly do you want to do?  Why are you trying to load
WinMM.DLL manually anyway?

> can u show me how to call the DLL-Entry address...?

You never call a DLL's entry point yourself.  It is called automatically by
the DLL loader.  In the case above, by LoadLibrary().

Because i don't want my programm to be depend directly to the "WinMM.DLL"
if it's existing, otherwise my programm would be directly "linked" to the DLL...
Only if the DLL is there, than the programm should use its function: "mciSendDtring",

sorry, no "entry point"...my mistake.....i mean: GetProcAddress( ) ....

how should i call:

        GetProcAddress((HMODULE)hInstance, "Name_Of_Dll_Function");


i remember, i've used something similar in the past....


in header...
-------------------------------------------------------------------------
private:
   typedef int (DLLFUNCTION)(int, int);

   DLLFUNCTION   *WinMM_DllFunction;

public:
    TDLLTest();
    void CallDllFunction(int iTest1, int iTest2);
}

// in cpp....


TDLLTest::TDLLTest( )
{
   HINSTANCE hInstance;

   hInstance = ::LoadLibrary("DelphiDLL.dll");
   WinMM_DllFunction  = (DLLFUNCTION*)::GetProcAddress((HMODULE)hInstance, "Name_Of_Dll_Function");
}

void TDLLTest::CallDllFunction(int iTest1, int iTest2)
{
    int iResult;

    if (WinMM_DllFunction)  iResult = (*WinMM_DllFunction)(iTest1, iTest2);
}
-------------------------------------------------------------------------

Why not?  That is a Microsoft DLL that is on all Windows systems.  Since you
are using the Windows Multimedia system anyway, you are better off
statically linking to it.  There is no point in dynamically loading it in
your code.

As it should be.  That DLL is always available.

> Only if the DLL is there

The DLL is part of the Windows OS, and has been since the days of Windows 95
and NT 3.1.  It is been available on all Sindows systems ever since.

That is how to dynamically load a DLL function.  So what exactly are you
having a problem with?  Please be more specific.

>    typedef int (DLLFUNCTION)(int, int);

Use a pointer in the typedef, not in the variable declarations:

    typedef int (*DLLFUNCTION)(int, int);

    DLLFUNCTION WinMM_DllFunction;

    WinMM_DllFunction  = (DLLFUNCTION) ::GetProcAddress(hInstance,
"Name_Of_Dll_Function");

    iResult = WinMM_DllFunction(iTest1, iTest2);

Well, actually you've answered my question :-)

i'll link my program staticly without LoadLibrary(...)

if the DLL is installed by default, i really don't need to call
it dynamicly at all....


thanks Remy !!!
