Are you by any chance explicitly adding any C/C++ standard libraries (C Run-Time Library or Standard C++ Library) to your link settings?

I write an app that record single keystrocke and can lately retrieve and send this keystrocke on another computer.
I need also to retrieve its name (ex: "home" for scancode 71)
Even I searched a lot about this I'm still not sure how to store this keystrocke in a file to avoid international issue.
Recording Wparam and Lparam (wm_keydown) seem interesting while I can latetely retrieve the name of the key on user computer in his hown language with:
GetKeyNameText(pMsg->lParam,lpString,4);
and retrieve the scancode with MapVirtualKey( pMsg->wParam,0);
1-will this work ?
2-are the virtual key the same on each computer or should I directly store the scancode. (and so how to retrieve the name?)
I'm somewhat lost while there is so much ways to code a key.
Thanks

Hi,
Is it possible to make an ActiveX-control draw itself to a memory DC rather than to the current DC?
What I would like to do is to extract a single frame from an animation (avi, mpeg, ...) rendered by the windows media player ActiveX control, and get the bitmap bits from it without having to actually draw the frame on screen.
Do I maybe have to use a raw multimedia API and not use the ActiveX at all?
I glanced through the media player SDK v7.0, but it seems to be focusing on how to manipulate skins rater than content.
Can I trick it into drawing itself into memory?

How can I prevent the size of the checkboxes in a CListCtrl to be dependent on the size of the titlebar?
Check out these two shots to see exactly what I mean:

(The default size is 18)

The COMCTL32 implementation of checkboxes uses item state images. Basically, you can mimic this behavior by setting your own state image list with CListCtrl::SetImageList and handling WM_LBUTTONDOWN to flip checkmarks. As a bonus, your app will run on plain Win95 without any COMCTL32 updates coming from IE, Office or other MS products.

Could you please be a little more specific?
I'm trying to learn MFC, and this is the first CListCtrl i've ever created :]

In this case, stick with default checkboxes. This is not a beginner-level issue.

Hi,
I have a nice subclassed CEDit class that controls input to exactly the characters I allow. And I have a CTreeCtrl with Edit labels style. I'd like to be able to use my subclassed CEdit to control what the user can enter in the edit part of the treeview.
It says that this can be done in the help:
During label editing, typically in response to the TVN_BEGINLABELEDIT notification message, you can get a pointer to the edit control used for label ....[you can]...subclass the edit control to intercept and discard invalid characters. Note, however, that the edit control is displayed only after TVN_BEGINLABELEDIT is sent.
I know what it's saying, and I know how to get this CEdit pointer. But I have no idea how to implement this as a CMyEdit. Is it as simple as just casting the pointer into a CMyEdit?
ie:
CMyEdit *p_MyEdit;
p_MyEdit = (CMyEdit *) m_MyTreeCtrl.GetEditControl();
or am i barking up the wrong tree totally?
I'm certainly getting in at the deep end, but learning a lot as I do it. So thanks everyone who's helpmed me in the last few weeks!

The cast will not work. You have two possibilities:
1) use API instead of CTreeCtrl methods. Send TVM_GETEDITCONTROL to get the HWND of the edit control. Pass the HWND to CYourEdit::Attach.
2) I'm not quite sure about this one: you can try to use CWnd::SubclassWindow on CEdit pointer returned from CTreeCtrl::GetEditControl.

SUperb, thanks Thomas.
I followed (ish) method 1, turns out to be a one-liner.
I added a CMyEdit member to my dialog class, and handled TVM_GETEDITCONTROL for the treeview.
Then:
m_PhoneEdit.SubclassWindow((m_Tree.GetEditControl())->m_hWnd);
That did the trick!

Subclassing a window requires that you create a CMyEdit object (such as a member variable in the C++ class that contains the tree), then after the code you posted, do
m_wndMyEdit.SubclassWindow ( p_MyEdit->GetSafeHwnd() ); m_wndMyEdit is the CMyEdit object I mentioned. Window messages sent to the edit control will then pass thru CMyEdit first.

Hello,
I hav a situation where i need to detect any changes in a specified directory. Changes here include new files comming in and updated files.
I have managed to use FindFirstChangeNotification functions to detect any changes in the directory. However the problem comes when i want to know which file is the affected ones.
Any ideas or hint would be great. Thanks

If you are running on NT, use ReadDirectoryChangesW() instead.

Thanks,
I have test run on ReadDirectoryChangesW() but I can't get it running. It keeps giving me a link error and that my ReadDirectoryChangesW() was not defined. I have included all the necessary header files but to no avail.
