Flash 2004 and C++ interactivity

Within the flash documentation it says it has the ability to communicate with C++ using the fscommand action. It also says that this can be accomplished with the use of ActiveX controls. Say I have a simple button and textarea in flash. I want to be able to pass a value from within the textarea to a C++ dll file when the button is clicked. The button code could be the following:
on (click) {
fscommand("messagebox", "This is a message from a box called from within Flash.");
}
How then do I set up activeX controls to be able to handle this fscommand and what code is also needed in C++ to be able to accept this string? Could this process also work in reverse sending a string from C++ to the Flash document?

Hope that helps!

Try this. First of all , you have to add the "Shockwave Flash Object" control in the Toolbox . If you right click on the toolbox and then select "add/remove item" you will be able to add the "Shockwave Flash Object" COM component . After that, create a control in your dialog. Associate it to a member variable.

void CMYDIALOG:oDataExchange(CDataExchange* pDX)
{
CDialog:oDataExchange(pDX);
......
DDX_Control(pDX, IDC_FLASHID, m_flash);
......
}

in CMYDIALOG.h

CShockwaveflash2 m_myFlash;

if you want to load a swf into the control, you can use this function:

CString swfFileName;
swfFileName("C:\\myswffile.swf");
m_myFlash.put_Movie((char*)(LPCSTR)swfFileName);

if you want to process the fscommand from the flash

in the .cpp

BEGIN_EVENTSINK_MAP(CMYDIALOG, CDialog)
ON_EVENT(CMYDIALOG, IDC_FLASHID, 150, FSCommand, VTS_BSTR VTS_BSTR)
END_EVENTSINK_MAP()

void CMYDIALOG::FSCommand(LPCTSTR command, LPCTSTR args)
{
//// fscommand from the flash will be received by this function
CString valor,comando;
valor.Format(args);
valor.MakeLower();
comando.Format(command);
comando.MakeLower();
// you can pass them to a CString variable and then use CString Compare method
.....
}


in the .h
DECLARE_EVENTSINK_MAP()
void FSCommand(LPCTSTR command, LPCTSTR args);

if you want to communicate with the swf from vc++ you can use a variable in the flash as a communication way. You should add a watch function that will be activated when someone writes the variable.
For example , in the first frame of the flash you can write:

var R; // this will be the variable for the communication

function init()
{

/// assign the watch to the variable R
this.watch("R", onRChanges);

}

function onRChanges(prop,oldval,newVal)
{
/// this function will be activated when the content of the variable R changes.

/// the format of the R variable will be VarName=valor&VarName1=valor1...

lvR = new LoadVars();
lvR.decode(newVal);
trace(prop);
trace(newVal);
for(var p in lvR)
{
trace(p);
trace(lvR[p]);
}

}

init();


and to write the R variable from vc++, you can use this:
CString valueForR="name=Odiseo&surname=DeItaca&school=athens";
m_myFlash.SetVariable("_root.R",(char*)(LPCSTR)valueForR);

well, i hope this helps.
sorry for my english.

Hi

I have to communicate with the flash file (i.e) .SWF file to my vc++ dialog. I have writen the same code but not working can u give some guide lines.
