In order to create a program that uses the API, you must #include jcam_dll.h in your source code and link to the jcam_dll.lib file in your project. In Visual C++, this is accomplished by going to:

Project > Properties > Linker > Input > Additional Dependencies

From there, enter the location of the jcam_dll.lib file. We suggest that you put it in your project directory.

Static Linking

If you statically link the API functions into your own application, you won't need to distribute jcam_dll.dll with your application. However, you do need to do five things:

• Link jcam_dll.lib with your project. 
• #define JCAM_STATIC_LIB
• #include jcam_dll.h
• Use the joescan namespace. 
• Call jsInitialize() before calling any other Joescan API functions. 

#define JCAM_STATIC_LIB
 #include "jcam_dll.h"
using namespace joescan;

main(int argc, char ** argv)
{
    if(jsInitialize() == FALSE)
        exit(0);

    //Your code goes here...
}

If you dynamically link the API functions to your own application, you will need to distribute jcam_dll.dll with your application. jsInitialize() will be automatically called by the Windows dynamic library loader. That leaves you with five things you must do:

• Link jcam_dll.lib with your project. 
• Distribute jcam_dll.dll with your application. 
• #define JCAM_DYNAMIC_LIB
• #include jcam_dll.h
• Use the joescan namespace. 

You should put the jcam_dll.dll file in your project's Debug and Release directories so your program runs when you test it. When you distribute your application, the jcam_dll.dll file must be in the search path for the program, probably the install directory.

#define JCAM_DYNAMIC_LIB
#include "jcam_dll.h"
using namespace joescan;

All the symbolic constants used in this manual are defined in the file jcam_dll.h.

The joescan Namespace

If you're using C++, you can either use the joescan namespace as above and in the examples, or you can fully qualify its members. For example:

joescan::JCONNECTION jc = joescan::jsOpenConnection("192.168.1.105");
