hi Albert Holguin,
I created Pointer variable Seperately for all threads.I made a mistake of using timers,now i removed timer.But how to terminate thread and how to find wheather thread is terminated properly or not.While exiting my application i am suspending thread and terminating it but still its not terminating.Is there any other way to terminate thread.Here is the code what i used.

here m_iCamNo is camera number(I used 16 cameras).
if(m_ThRecieveImage[m_iCamNo]) m_ThRecieveImage[m_iCamNo]->SuspendThread();

::TerminateThread(m_ThRecieveImage[m_iCamNo],90);


Is there any thing wrong in that.


Thanks in advance.

hi SAKryukov,

I used AfxBeginThread to create thread.

CWinThread* m_ThRecieveImage;
m_ThRecieveImage = AfxBeginThread(RecieveImage,m_CamNo,THREAD_PRIORITY_NORMAL,0,0,NULL);

I am using 16 cameras for each camera i am creating one like this.And in timer also i am calling this continuosly.

Can you please help me out from this problem.

I developed my server using visual C++ by using CSocket

Actually I am able to stream like a video in my client program (i.e., in my application GUI) but in web browser i am not able to stream like video.If I enter ipaddress and port number in web browser it sending request only once again if i press refresh it sending request again,so how to send request continuously from web browser once i enter ipaddress and protnumber.

Regards,
RamyaRaj.

is there any way of finding from where request came.Means i am using accept function which gives the handle of the socket from where i got the request,so from that i can access my image continuosly if i got request from any web browser.Can you please help me out from this problem.

Can anyone help me out from this problem still i dint get any solution for this.Thanks to all in advance

Regards,
RamyaRaj.

yes your right

No ,It should stick to my window it should not pop up like a new window.If it stick to my window then the interface is like preview is on my main CWnd not on separate window.So when i click on any Video window i need to make that particular camera as active camera and i need to do further process based on that.

So when i use the following code i am able to stick the VideoWindow to my Main CWnd

pGraphList[CamNo]->QueryInterface( IID_IVideoWindow, (void**) &pVidWin[CamNo]); pVidWin[CamNo]->put_Owner((OAHWND)hWnd); pVidWin[CamNo]->put_WindowStyle(WS_CHILD | WS_CLIPSIBLINGS); pVidWin[CamNo]->put_MessageDrain( (OAHWND)hWnd ); pVidWin[CamNo]->put_Visible(OATRUE); pVidWin[CamNo]->SetWindowForeground(-1);


But I am getting problem at click events.

IT IS LIKE OPENING THE CAMERA PREVIEW IN A SEPERATE WINDOW NOT STICKING ON TO MY MAIN CWnd

hi barneyman,

Why these are opening in Active movie window how can I solve this problem.

Regards,
RamyaRaj.

hi barneyman,
I tried your solution but preview from all cameras are opening in activewindow when i tried to use WS_CLIPSIBLINGS its generating error

when i used
Create(WC_STATIC, "", ws_child | ws_visible, where, parent, id);
what you suggested me its providing error like create doesnot take 6 parameters so i did in the following way
CWnd* pWnd = new CWnd;
pWnd->Create(_T("STATIC"), "", WS_CHILD | WS_VISIBLE, where, parent, id);
wheather this may be a cause for opening in Active window mode

And also
when to call this
void OnLButton(UINT flags, Point where)

in our child window class
or it will automatically enters into it when we click on IVideoWindow because of message drain.Can you please help me out from this problem.Whether I am going wrong anywhere.Thanks in advance.

Regards,
RamyaRaj.

sorry really i dint get you how to pass that message can you send me once again clearly waht i have to do
I dint define any clickevents to my IVideoWindow
how can i define this
ChildWnd::OnLButtonDown( UINT nFlags, CPoint point) {
---------
}

Sorry to trouble you

Regards,
RamyaRaj

pVidWin[CamNo]->put_Owner((OAHWND)hWnd);
pVidWin[CamNo]->put_WindowStyle(WS_CHILD | WS_CLIPSIBLINGS);

ya i created seperate Window for each message but how to know which iVideoWindow is giving this event.When i click it is entering directly into ON_LbuttonDown Function Only i am getting coordinates of the point nothing other than that.

when i am using MapWindowPoints it is not accepting 4 parameters as argument even i included winuser.h windows.h user32.lib also linked anything else i have to add to use this MapWindowPoints


Regards,
RamyaRaj

yes even i used put_MessageDrain evevt to pass handle of my click events to main window but when i click on IVideoWindow the coordinates what i am getting are corresponding to that window but not to main Hwnd.

Hi Olivier Levrey,
I am calling this ClientToScreen function in LButtonDown function of my main Dialog.when i click IvideoWindow i am getting only the information about point where i clicked but not from which IvideoWindow i got this Click.I am Creating Seperate handles to all IVideoWindows.I am using put_MessageDrain event to pass message handlings from IvideoWindow to my main Dialog Message events like LButtonDown,OnMouseMove,RButtonDown etc.,so wen i left click on IvideoWindow it passes message to ON_LButtonDown Function of my MainDialog.Can you Help me out from this Problem Thanks in Advance.

RamyaRaj.

hi barneyman,
thanks for your solution,but here in MapWindowPoints we need to pass first two arguments as from which Window to which window we need to change the coordinates but here when i click the IvideoWindow i am getting only the information about point where i clicked but not from which IvideoWindow i got this Click
so how can i pass HWnd information to that function can you help me out from this problem.Thanks in Advance

Regards,
RamyaRaj

hi Olivier Levrey,
Thanks for your reply but my problem is when i click on the window means not not on the main window it is on IVideoWindow what i used for streaming video . If i convert the coordinates using Clienttoscreen method for all IvideoWindow's its giving same coordinates is there any method to convert that coordinates to screen coordinates.Thanks in Advance.
