I'm writing a DLL that uses DirectShow to capture some video off a firewire (WDM) device, and I'm having a small problem.
We have an MFC app that creates the view in the EXE, and then passes a pointer to the view to the DLL so that we can put the preview window into the view. If the preview window consumes all of the client rectangle, I can't get the veiew to respond to mouse clicks. If I maximize the view window, I get a border of unused area around the preview window that responds to mouse clicks.
Can anyone provide any clues,documentation, books, magazines, help from aliens, anything?

Can you call SetCapture() in your view ? That's how I usually get around those sort of problems, although I often find it's tricky to get the code to a state where the mouse actually responds as you'd expect.

I basically can't change the exe. Anything I do has to be done in the DLL since we support many different DLL which perform similar functionality, using WDM instead of Video For Windows.

I've got myself a treeview (yeah!). When I select a node, the tvitem structure I get with the message doesn't contain the image (TVI_IMAGE) attribute. Is there a way of finding out what image the selection has? I'd like to use the image as a way of knowing what type of object was selected.
Thanks,
WAVK

You'll have to call CTreeCtrl::GetItem, passing HTREEITEM from NMTREEVIEW. Don't forget about TVIF_IMAGE flag.

I need to know when my parent gets WM_SIZE and WM_MOVE messages (i am a CButton derived control  )
any help?
|

Your parent must co-operate and call some method exposed by button. There's no built-in notification going from parent to child during move/size operations.

Hello, the codegurus around the world.;)
We can put the code likes SendMessage with the user-defined message or some Get function
from Dialog (or button) in WM_SIZE and WM_MOVE of the parent's message handler.
The only issue is how we get CWnd of the child dialog or the button of its dialog.
There are many ways to do this.
Have a nice day!

How can I force all buttons, edit- boxes and list-boxes to be resized when resize the application window ? Objects should be smaller but still at the same location within the application window.

If you're using MFC you may have a look at ResizableLib on this site.
If using plain Win32 APIs, that same article can give you some ideas.

this is the easiest way to place an icon on a button:
// Button = m_SafeButton
// Icon = IDI_FLOPPY
m_SafeButton.SetIcon(AfxGetApp()->LoadIcon(IDI_FLOPPY));
m_SafeButton.EnableWindow( true);
that´s all.

I want to control word through the interface the word provided. But I found some problems. I found not all the controls such as buttons, comboboxs are window control. They don't have the window handles. But I want to process some messages it sended. you can found this through spyxx.What can I do?
thanks to all the programmers who have helped me.

How on earth do you presume to have found that a button or combobox in Word does not have a HWND associated with it ? I believe Word does not use MFC, ( so no CWnd ), but I can't see how it could possibly show you a button without it being a window, with a handle.

He's probably thinking about Word toolbars - the comboboxes and buttons you can see there aren't real tax-paying, HWND-having windows.

I want to use my own dialog to control word. for example, I want to control the "insert -> index and content" dialog in my code. So I can send a message to set the checkboxes status. But i can't get the checkboxs' window handle now.

What are you trying to make Word do? Which controls/windows are you trying to control?
You seem to be approaching this from a strange angle. What do you want to achieve?

to be simple, I want to create a word document with my own format. And I will provide some dialogs to let people coustomize the format. so have to use some word's automation interface. But when a dialog of word do modaled, I can't get the status untile the dialog ended. for example, in the dialog "insert -> index and content" there are some check boxes, and i want to set the check boxes' status in my code. what can I do?
thanks to all the programmers who have helped me.

Hello, the codegurus around the world.;)
It seems that you want to use some functionality of Word.
We can use Word Automation to access all Word functionality in our application.
Have a nice day!

right! But when the dialogs of the word show modal, I can't use the interfaces, I have to waiting for the user to select an item. How can I do it automaticly?

I need in my application to resize at each step of a for loop 2 arrays. I have read that for reallocate memory, it's better to use <vector>, rather than use the definition of the usual pointer. But, as i'm a beginner in this kind of knowledges, i would like to know if someone could explain me how i could declare 2 arrays, with 2 differents size, so that at each step, as i use an iterative method, one of this array "becomes" the other.
thanks in advance

I presume you said it's better to use <vector> ? You can get vector to preallocate the memory so that push_back doesn't reallocate every time. If the two vectors are going to be different sizes, how will one 'become' the other ? You're going to copy some values across but not all ? The vector being copied to grows ? I'm confused....

As i said, i use an iterative method. In a for loop, for example consider: for(i=1;i<=n;i++)
At the beginning i would declare 2 pointers:
double *Qi1=new double [ni1]
double *Qi=new double[ni]
So, if you consider that i correspond to a date, Qi is a pointer on an array which contains ni+1 values at date i and Qi1 a pointer on an array which contains ni1+1 values at date i-1.
In fact, to calculate the value on the array pointed by Qi, we need to know the values at date i-1. After, we have calculated the values, we need to go to the next step, and calculate value at date i+1, so that Qi "becomes" the preceding array, so i have to consider that values in Qi have to be put in Qi1.

Your explanation and code fragment are a little confusing, perhaps posting a more detailed code fragment would make it clearer.
