External Interface Fails in MFC Unicode Application

[Bikram Thapa]

Hi Support,
I am having a MFC application in Unicode.

My following call is failing

Code: Select all

LRESULT CMainFrame::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{   
   if (WM_NOTIFY == message)
    {
        LPNMHDR lpNMHDR = (LPNMHDR)lParam;
      switch (lpNMHDR->code) {
         case FPCN_FLASHCALL: {
            SFPCFlashCallInfoStruct* pInfo = (SFPCFlashCallInfoStruct*)lParam;
            CString xmlStrResult,xmlStrReturned;
            xmlStrResult = pInfo->request;
            ....

            xmlStrReturned = _T("<invoke name='SetPath' returntype='xml'><arguments><string>C:\Documents and Settings\cipl\Application Data\APP\data\ccc\content\df731222-57a8-49b7-a9a1-8f3b2f17e47c.flv</string></arguments></invoke>");
            FPCSetReturnValue(myflashMap[i].m_hwndFlashPlayerControl,xmlStrReturned.GetBuffer(xmlStrReturned.GetLength()));

                  break;
               }
            }
            return CFrameWnd::WindowProc(message, wParam, lParam);                                                         
         } // case flashcall
      } // switch ends
   }
   return CFrameWnd::WindowProc(message, wParam, lParam);
}



The xml string sent to flash fails.

Thank you for your question.

What if you change character settings to ANSI?

Thank you.

[Softanics]

BTW, you should replace each '\' with '\\' of xmlStrReturned...

[Bikram Thapa]

Hi Support,
I did put extra '\' in the above code, but still no luck. The same xml string works in .net edition. I did to run the MFC Sample provided for external interface in Unicode and it works.
Do I need to do any thing differently.
Please guide.

Thanks and Regards
Bikram

What if to change:

Code: Select all

FPCSetReturnValue(myflashMap[i].m_hwndFlashPlayerControl,xmlStrReturned.GetBuffer(xmlStrReturned.GetLength()));

into

Code: Select all

FPCSetReturnValue(myflashMap[i].m_hwndFlashPlayerControl, (LPCWSTR)xmlStrReturned);

?

Thank you.[/quote]

Hi Support,
No luck with following change either,

FPCSetReturnValue(myflashMap[i].m_hwndFlashPlayerControl, (LPCWSTR)xmlStrReturned);

I tried to extend MFC Sample sample4 this way

Code: Select all

//MemberAdded To TransparentFlashPlayerControlWnd.h
public:   
   HWND m_hwndFlashPlayerControl;


Changes in Sample04_Translucency.cpp

Code: Select all

pFlashProjectorWnd->hwndFlashPlayerControl = hwndFlashPlayerControl;
.....................
FPC_LoadMovie(hwndFlashPlayerControl,0,_T("c:\\main.swf"));


Changes in TransparentFlashPlayerControlWnd.cpp

Code: Select all

LRESULT CTransparentFlashPlayerControlWnd::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
   switch (message)
   {
      case WM_NOTIFY:
      {
         LPNMHDR lpNMHDR = (LPNMHDR)lParam;
         if (hwndFlashPlayerControl == lpNMHDR->hwndFrom)
         {
            switch (lpNMHDR->code)
            {
               case FPCN_FLASHCALL:
                  SFPCFlashCallInfoStruct* pInfo = (SFPCFlashCallInfoStruct*)lParam;
                  CString xmlStrResult,xmlStrReturned,romName;
                  xmlStrResult = pInfo->request;                     
                  FPCSetReturnValue(hwndFlashPlayerControl,_T("<invoke name=\"SetPath\" returntype=\"xml\"><arguments><string>C:\\b1fd4eb0-6db9-4810-a3cb-0063700cd0af.flv</string></arguments></invoke>"));
                  break;
            }
         }
         break;
      }

The Application does not enter the WM_NOTIFY section.
I can provide you the main.swf file. this file first makes an external api request and then simply shows back the data send through FPCSetReturnValue(), in message box.
To which email ID should I send the testing main.swf file.[/code]

The Application does not enter the WM_NOTIFY section.

WM_NOTIFY is sending to a parent window of a f-in-box control, not to the f-in-box window.

Thank you.

[Bikram Thapa]

I have sent an email attaching the test swf file.
Thanks

[Bikram Thapa]

Hi Support,
I had emailed, the test swf file. Where you able to run the fs external interface.

Sorry for the delay.

What I can't undestand is why do you use "<invoke>...</invoke>" as a return value (btw, I've just tried it and FPCSetReturnValue returns S_OK). Usually, if you want return, for example, a string you use something like that:

Code: Select all

FPCSetReturnValue(m_hwndFlashPlayerControl, _T("<string>tratata</string>"))


Can it be a problem?

What does FPCSetReturnValue return in your test?

Thank you.

[Bikram Thapa]

Hi,

Sorry for the delay in replying; had been busy with other issues. I did try to do what you suggested, but no success. Though the function returns S_OK, no movie is played nor any response from flash movie.(the dot net code works fine.) I will email you the screen shot of what is shown, when a successful request is made.

Regards
Bikram.

[Bikram Thapa]

Hi Support,
I had emailed the main.swf file, and then a screen shot of what main.swf shows as output. Where you able to run it successfully?

Thanks and Regards
Bikram...

[Softanics]

I've just emailed you.

Thank you.

Hi Artem,
I have sent the mfc test project, please try at your end.
Thanks and Regards
Bikram

[Bikram Thapa]

Hi Artem,
Any luck with the mfc test project, I had sent earlier?
Thank you
Bikram
