<How can i insert a C++ file with a .h file in matlab? I have no experience in writing codes. I want to acces a .dll file from a programm to get data from. There's an example, where c++ builder is used to show the data. I need a main.cpp and the .h file to get data into the workspace. But how can I do this?

Hi Friedrich,
First, thankyou for your answer. It's not a source code. The software use a .dll file which you can acces to get data. To do this, a .h file and a .cpp file is written to give an example of how you can acces data from the .dll file.
This is the .cpp file:
#include "sflib32.h"
DAC740* Dac740 = NULL; /****************************************************************************** DAC740 constructor will initialize this class for use. This routine will call the Windows function LoadLibrary to load the dll into memory, then all of the needed function address will be obtained via GetProcAddress. If an address is unobtainable, a message will be displayed, FreeLibrary will be called, and the module instance handle will be set to NULL. ****************************************************************************/ DAC740::DAC740(void) { register int i; LPVOID lpMsgBuf; char szWorkBuff[300]; typedef struct { void** pFunc; char* szFuncName; }PROC_TYPE;

I think i need to say in the .cpp file to get the data and to write it to the workspace so that i can use it in matlab. Any idea how to do this?

try to use the loadlibrary command in MATLAB to load the DLL into MATLAB:
If this shouldn't work, write a mex file in which you call the DLL like in the example given above.

I tried to use the loadlibrary command using:
loadlibrary('sflib32.dll','sflib32.h','addheader','regdef.h','addheader','nge.h','addheader','SFC_Numericdefines.hpp') The header files are included in the sflib32.h file as #include.
But i get the following errors:
Warning: Message from C preprocessor: lcc preprocessor error: C:\WINDOWS\sflib.h:8 C:\WINDOWS\sflib32.h:20 Syntax error in #ifdef/#ifndef lcc preprocessor warning: C:\WINDOWS\SFC_NumericDefines.hpp:44 C:\WINDOWS\sflib32.h:22 No newline at end of file
