SDI CTreeView question...

Hello,
I have SDI app of type CTreeView.. My question is, is there a way of moving the tree over x number of pixels and down y number of pixels?? I'm using the OnPaint function to paint a border around the outside of the tree, the only problem is that the tree is so close to the top and left side of the window that my border covers part of the tree...

Any ideas??

If you inherit from the TreeView, you could override the WM_NCCALCSIZE / OnNcCalcSize message
to give yourself some non-client area to put a fancy border in using WM_NCPAINT / OnNcPaint.

Thanks for the quick reply.. I have been trying the following... The only problem I am having is I can't seem to paint on the non-client area.. I can see a 5px gap all the way around the tree, even when I paint my border.. Here is what im trying on my WM_NCCALCSIZE msg..

LRESULT CMyTreeView::WindowProc(UINT message, WPARAM wParam, LPARAM lParam) 
{
	if(message == WM_NCCALCSIZE)
	{
		if(wParam == TRUE)
		{
			RECT* prect = (RECT*)lParam;

			// Create a 5px gap around the client area..
			prect->right = prect->right - 5;
			prect->left = prect->left + 5;
			prect->top = prect->top + 5;
			prect->bottom = prect->bottom -5;
   
			return 0;
		}
	}
	
	return CTreeView::WindowProc(message, wParam, lParam);
}

Any ideas? Am I doing this all wrong?

I actually had CTreeCtrl in mind when I replied earlier! Doh...

Having a quick look at the DSK for calcsize, when wParam == TRUE,
lParam = (NCCALCSIZE *), not (RECT *). But you are getting away
with it! A five pixel gap is what you asked for.

How are you trying to paint? You need to be using OnNcPaint.

Iain.

NM I figured it out... THANKS!

DEBUG / RELEASE PROBLEM

Hi
I have developed a client server program with RTP/RTCP and IPV6 communication. The RTP Library is given as both debug and release mode. When the application changes from debug mode to release mode the data sending is not happening. I am using WS2_32.dll for socket operations. Could anybody suggest the reason or any clues to get it resolved and make it running in release mode. Any suggestions are appreciable.

Regards,
Sankaran Cry | :((

How to automatically split a big header file

My main header file is bloated to the max, now reaching 6000 lines with many classes. I started editing it by hand riping out classes and creating their respective header/source files, but it is taking forever.

It would be GREAT if someone has or knows of a utility which will do this, ideally this utility would create class.h and class.cpp files for every class in a header file.

Just write a macro to do it. Should take you about 1/2 hour to make the macro, searching for "class" and what not, then it'll take the macro about 30 seconds to run.

Sorry, i already finded out that i can set property of dialog: control & center. But i don't see the titlebar (and the option 'titlebar' is checked)

Thanks

Exporting registry key programatically?

Abin13-Mar-03 1:49

13-Mar-03 1:49

Is there any way in C++/MFC that we can export a registry key and all its subkeys/values and save the contents to a file, like we do using "regedit.exe"? "RegSaveKey" will not work since it can only save all contents of a root key.

Read the documentation for RegSaveKey once again :

hKey <br />
[in] Specifies a handle to the key where the save operation is to begin, or any of the following predefined reserved handle values: <br />

From MSDN:

RegSaveKey
The RegSaveKey function saves the specified key and all of its subkeys and values to a new file.

Specifies a handle to the key where the save operation is to begin, or any of the following predefined reserved handle values...

So RegSaveKey also saves non-root keys.

Port 0x64 is the keyboard command port. 0xAD is the command that disables the keyboard. (0xAE renables it.) This is usually one of the first steps in enabling the A20 line in the old IBM AT and its clones to get access to memory above 1MB. Wink | ;)

Use GetIconInfo() to get the HBITMAP corresponding to the icon, then add that bitmap to the images available for the toolbar with TB_ADDBITMAP.

SOCKETS - break the blocking "listen" command?

Daniel Strigl13-Mar-03 0:25

Daniel Strigl

13-Mar-03 0:25

Ok, when I am using the send and recv commands
in the blocking mode I can break the blocking wait with the shutdown
command, but how can I break the blocking listen command?

I use the socket functions (listen, bind, recv...) in a single thread and
waiting with the listen function for some clients. If the user ends the application I
want to end the thread and for that I want to break the listen command!
