davidek (3/3) Jan 17 2007 Yes, i included windows.h before casioio.h.

Bertel Brander (27/30) Jan 17 2007 Strange.

Hi!

Im a newbie to C++ and have a problem compiling with the DMC.
I included a header-file (.h) into an very simple cpp-programm.

In this file is e.g. a line like this:

int WINAPI CasioIO_RespondToReceive(HCASIOIO handle, BYTE rows, BYTE columns,
double * values);

DMC reports errors cause of an missing "," and errors cause the "*", but the
code should be correct.
Have i to change the lines for DMC? Or is this header-file-line wrong?

I don't think it is a standard one.

Do you include windows.h before casioio.h ?
If not, try it.

Do you have a .lib file for the dll?

Strange.

I wrote this:

#include <windows.h>
#include "casioio.h"
HCASIOIO Handle;
void SendFunc()
{
}
void RecvFunc()
{
    double X[] = {1, 2};
    CasioIO_RespondToReceive(Handle, 2, 3, X);
}
int main()
{
    CasioIO_Init(1, 0);
    Handle = CasioIO_Open(123, 321, SendFunc, RecvFunc);
}

It compiles without problems.
casioio.h is a file with the content you posted.

Can you post a complete example that show the problem?
Can I download casioio.h/.dll/.lib ?

Hi!

The background to my problem: I started to learn java-programming. Now i want to
call functions of this dll out of java. For that i use the JNI (Java Native
Interface), which allows to use DLLs in java.

I have to call the CasioIO.dll out of an new DLL, that i try to create
(Wrapper).
But i simply dont get the DLLs functions in the cpp-programm.

At he current state the Optlink reports "Error 42: Symbol Undefined" about the
CasioIO-methods.

Here is a link to the CasioIO-download:

You could do:
#include <windows.h>
#include <iostream>
#include "../SDK/vc/casioio.h"
#include "jni_test.h" //This includes the JNI. It is an header file 
created by a java-sdk-tool.

typedef int WINAPI (*CasioIO_UninitPtrT)();
CasioIO_UninitPtrT CasioIO_UninitPtr;
typedef int WINAPI (* CasioIO_InitPtrT)(BYTE comport, int iotype);
CasioIO_InitPtrT CasioIO_InitPtr;


JNIEXPORT jint JNICALL Java_jni_1test_Uninit(JNIEnv *env, jclass)
{
    return CasioIO_UninitPtr();
}

JNIEXPORT jint JNICALL Java_jni_1test_Init(JNIEnv *env, jclass cl, 
jshort comport, jint iotype)
{
    return CasioIO_InitPtr(comport, iotype);
}

void InitPointers()
{
    HINSTANCE Library = LoadLibrary("CasioIO.dll");
    CasioIO_UninitPtr = (CasioIO_UninitPtrT )GetProcAddress(Library, 
"CasioIO_Uninit");
    if(!CasioIO_UninitPtr)
    {
       std::cout << "Failed to find CasioIO_Uninit" << std::endl;
    }

    CasioIO_InitPtr = (CasioIO_InitPtrT )GetProcAddress(Library, 
"CasioIO_Init");
    if(!CasioIO_InitPtr)
    {
       std::cout << "Failed to find CasioIO_Init" << std::endl;
    }
}

__declspec(dllexport) BOOL APIENTRY DllMain(HANDLE hModule, DWORD 
ul_reason_for_call, LPVOID lpReserved)
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
       InitPointers();
       break;
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
       break;
    }
    return TRUE;
}

The above code compiles and creates a jni_test.DLL with this command line:
dmc -I\j2sdk1.4.2_10\include -I\j2sdk1.4.2_10\include\win32 -mn -WD 
jni_test.cpp kernel32.lib

You need to do something else than stc::cout << "..." in case of errors.

Hi!

Thank you very much! That solution works fine! I got an value back from the
