u could try the following
CFont font;
font.CreateFont(0,0,0,0,FW_NORMAL,FALSE,FALSE,0,ANSI_CHARSET,OUT_DEFAULT_PRECIS,
CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH | FF_SWISS,"MS Shell Dlg");
((CEdit*)GetDlgItem(IDC_EDIT1))->SetFont(&font);
this will change the font in that particular edit box

There's a child windows for which I want to record its visibility after the main program exits. But the value IsWindowVisible() in OnDestroy() returns always zero, where else can I record its visivility before it gets destroyed?

OnDestroy() is called after the CWnd object is removed from the screen.

Try OnClose().

You can handle the LVN_ENDLABELEDIT message in the CListCtrl, and in the message handler, post a custom Windows message to the parent:
void CMyListCtrl::OnEndLabelEdit(NMHDR* pNMHDR, LRESULT* pResult)
{
...
GetParent()->SendMessage(WM_LISTWASMODIFIED);
...
}
There's a great article on custom windows messages somewhere on CodeProject. I don'w remember who wrote it, but if you google, "custom windows messages codeproject", you should find it.
Hope this helps.

This message will not be sent, when i use SetItemText to change the item
text.
I want the parent to be notified when SetItemText is called, because I don't call SetItemText in CListCtrl's parent.

|
|
When an item is changed, the control will send a LVN_ITEMCHANGED notification to its parent.

Hi,
I have a VB6 application with a listview control in it. I have written an app in VC++ to
get the handle of the ListView control of the VB6 app.Then I used Jeff Ritcher's suggestion
from http://www.microsoft.com/msj/0997/win320997.aspx and according read the items from the
listview.Then I have to select the item. The problem comes here.When I select an item in the
listview, it gets selected ,but the previously selected item is still hilighted.The multiple
selection property of the listview is set to false.I have also tried to deselct the items.But
it didnot work.I am pasting the code below:
void CListtestDlg::OnButton1()

By "flat" do you mean without the 3D style?

The only way I can think of is to not load the 3D library (CTL3D32.DLL). I'm sure there's a way to do it on a control-by-control basis but I've never been inclined to find out.
Another option is to play around with the other styles for that control and see if any of them render it non-3D.

What steps should I do to read struct data in one application from another?
I'm trying to read a data structure in one application from another. I have the window handle of the application with me. And I also know the struct.
I need to get the structure pointer through USERDATA param of the window. In the application which owns the struct data places the address of struct data member in the window's USERDATA param by using SetWindowLong(*this,GWL_USERDATA,LONG(&st)) fn.
If a simple integer value is stored as USERDATA, I can read it by GetWindowLong(*pWnd,GWL_USERDATA) fn.
But if address of the structure data member is stored in it, I cannot read it in my application.
Should I use GlobalAlloc function for this purpose?
If so what are the necessary steps that I should do?
Please guide me!

Are you writing both apps, or trying to hack into one ? If the former, then the WM_COPYDATA message is your best bet.

Yes. Both the applications are mine. But there will be more than one instances of the first one.
Your suggestion is good, no doubt. But if I can read the struct directly, it will be most suitable for me.
Can you suggest an idea?
Thank you.

Well, definately not the hack you're pursuing now.

In general, you can not pass pointers between applications.
Each process has its own address space, the operating system maps the process specific address to a physical memory address. So process A address 0x00123456 may map to physical address 0x11111111, and process B address 0x00123456 may map to physical address 0x22222222. Don't even think about trying to get/pass physical address'.
You must pass the data.
As Christian said you can use WM_COPYDATA.
There are a number of other ways as well e.g. pipes, memory mapped files, ...
