Send message is not used to send messages between classes but to send a message to a specific window. If your class is not managing a window, then you cannot send a message to it.

Use SendMessage() or PostMessage().

Hi,
I'm creating an ActiveX control which will function like a combobox but instead dropdown a treeview (ie. CComboTree:COleControl). For stage one, i will only suppport the Dropdown style. I like to know how i can work out and set the maximum height of the combobox (ie. the editbox and button) to the current font height in the PreCreateWindow() function, just like a standard windows combobox does.
Thanks,
Lee

Hello Geeks,
We have AdRotator Control that can be used on Web Forms to display an Advertisement (Ad).
Is there any other similar control that can help me to display Advertisement on Windows form or Dialog box.
What I am trying to accomplish is something like this....
I want to get some info about an Ad from Server and store that info on my PC and then display that info in the form of Ad on dialog box. Also the Ad should rotate.
Can AdRotator Control which is used on Web Form can be used on Dialog box.
Or is there any other similar control that can display information which will keep rotating.
Thanks in advance.

Hi all..
Well, as in the subject: how can I control the frame rate of a video in DirectShow?
I am using DirectShow to play a video and blend a rectangle that moves along the video, which positions are stored in an array. I use SetTimer() to change the rectangle's position, but it seems that the timepoint in the timer doesn't match the frame rate of the video. So I'm thinking of controlling the frame rate of the video instead..
Thank you in advance...

Hi,
I think you can use the FrameRate attribute to get the frame rate.

Hi
I know that function too... but it seems that it is not that easy to change the frame rate.
Perhaps I should change the question: how to control the frame rate using DirectShow?
thank you

Why change the framerate? Wouldn't that change the motion of the video?
Since you have a "clock" already because you're playing video you shouldn't need to use a timer.
You can base your motion on the timestamp of each frame.

Then, why you are creating it ?
You can use ShowWindow(SW_HIDE) though.

Hi,
I dont want to hide the entire window instead of that I have to hide a dialog control...
Siddharth

this is the same function to use... 
CButton* pButton = GetDlgItem(IDC_MY_BUTTON);
pButton->ShowWindow(SW_HIDE);
|

|
|

Thanks,
It's working but we have create instance for CWnd,
CWnd* pButton = GetDlgItem(IDC_MDGRPX1);
pButton->ShowWindow(SW_HIDE);

Toxxct was saying same thing,
CButton* pButton = dynamic_cast<CButton*> (GetDlgItem(IDC_MY_BUTTON)); pButton->ShowWindow(SW_HIDE);
As window returned will be of type CButton in this, you need to use cast operator.

actually, no. the GetDlgItem() function always returns a CWnd*, but thanks to polymorphism, every CWnd inherited classes, you don't need to cast explicitely.
however, and your code is good on this, I always prefer to explicitely type cast because the person who will re-read the code later can understand easily what we wanted to do there.

You are not getting my point. In Case of buttons, pointer returned will of of CButton type. Remember thats why down casting it to(dynamic_cast) CButton* is succesful. Otherwise it would have made it NULL
toxcct wrote: every CWnd inherited classes, you don't need to cast explicitely.
Unless you needed functions from CWnd class. To
To understand, what I wanted to say, see pointer returned by GetDlgItem in debugger window.

is it ?
does the CButton class overload the GetDlgItem() function ? i don't think so.
I still think all that is done here happens because of polymorphism (or i still don't get your point...  )
BTW, i don't have an IDE with me, so not able to test anything.
but what i think you see in the debugger is because you assign it to a CButton* pointer. what if you assign a CWnd* variable ?
