I am trying to do a dll call.
I am trying to follow the example listed on the web for doing it, and have setup a dli, and putting the code in the for trying to do it. When I follow the example I get errors.
The winmm.dll is used to play sound, and done as sndPlaySound and you pass a file name, and some flags. At this point I am not even trying to make the actual call, but just try and get it to compile with the dli, and the .cpp setup for it.
Any help with this?
I have included the code below.
The errors that I am getting are as follows:
C:\MyApps\t2/winmm.dli(2) : error C2061: syntax error : identifier 'sndPlaySound'
C:\MyApps\t2/winmm.dli(2) : error C2091: function returns function
C:\MyApps\t2/winmm.dli(2) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
C:\MyApps\t2/winmm.dli(2) : error C2143: syntax error : missing ';' before '*'
C:\MyApps\t2/winmm.dli(2) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
C:\MyApps\t2/winmm.dli(2) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
C:\MyApps\t2/winmm.dli(2) : error C2065: 'sndPlaySound' : undeclared identifier
I am not even at this point trying to execute the dll, but just get it listed.
Here is the code in the winmm.dli:
FN(STATUS, sndPlaySound, (String lpszSoundName, long uFlags))
In the t2.cpp I have the following
#include "t2.h"
#define DLLFILENAME "winmm.dll"
#define DLIMODULE winmm
#define DLIHEADER <t2/winmm.dli>
#define DLLCALL sndPlaySound
#include <Core/dli.h>
t2::t2()
{
CtrlLayout(*this, "This plays a file");
}
GUI_APP_MAIN
{
t2().Run();
}
