unable to get FSCommand to work

[firegod]

Hi All,

My code looks this below, and my problem is when I call FSCommand from my .swf movie it doesn't work properly. The listener gets called and the switch detects the FPCN_FSCOMMAND correctly but the lparam is zero causing an exception due to pInfo being null.

I'm using the latest f in box demo, on Windows XP SP2 all compiled using VS2005.


Any ideas what I'm doing wrong?

Code: Select all

#include <atlbase.h>
#include <atlwin.h>

#include "f_in_box.h"
#pragma comment(lib, "f_in_box.lib")


LRESULT CALLBACK MyWindowProc(HWND,UINT,WPARAM,LPARAM);
void WINAPI Listener(HWND hwndFlashPlayerControl, LPARAM lParam, NMHDR* pNMHDR);

Thank you for your question.

/******************************************************************************************
* FUNCTION : Listener
* ACTION :
* PARAMETERS :
*******************************************************************************************/
void WINAPI Listener(HWND hwndFlashPlayerControl, LPARAM lParam, NMHDR* pNMHDR)
{
switch (pNMHDR->code)
{
case FPCN_FSCOMMAND:
{
SFPCFSCommandInfoStruct* pInfo = (SFPCFSCommandInfoStruct*)lParam;

MessageBox(hWnd, pInfo->command, _T("FSCommand(): command"), MB_OK | MB_ICONINFORMATION);
MessageBox(hWnd, pInfo->args, _T("FSCommand(): args"), MB_OK | MB_ICONINFORMATION);

break;
}
}
}

lParam of the Listener is a lParam that is passed to the FPCSetListener, use it to provide additional information to the Listener (for example, you can cast passed lParam to an object pointer). To retrieve SFPCFSCommandInfoStruct* use the following code:

Code: Select all

SFPCFSCommandInfoStruct* pInfo = (SFPCFSCommandInfoStruct*)pNMHDR; // don't cast lParam, cast pNMHDR

Thanks Artem,

A super speedy reply and it fixed my problem. Thanks and if I can get
communications going the other way into my flash movie I will be buying your product.
