Damn, that is what I saw.
Maybe I should write an article on that.

Hi,
I am creating a Header control to fit across the top of a custom grid I am writing.
The problem is this: When I change the colour scheme of Windows, the header control does not repaint itself correctly - it still uses the old colour scheme.
Does anyone know an easy way to get the header control to update it's colours? (i.e. without destroying/creating it again). I know it must be possible, because Header controls created by other apps don't have this problem (and I checked with Spy++ to see if they get recreated, and they don't...)
Any ideas?
James.

Handle WM_SETTINGCHANGE in your main window, and forward it on to the header control.

Mike,
Thanks for the fast response.
Unfortunately, I still can't get it working..
I'm forwarding WM_SYSCOLORCHANGE and WM_SETTINGCHANGE
to the header control (checked with Spy again to make
sure it received them)..no luck I'm afraid.
The border colours (i.e. highlight and shadow) change
colour correctly, but the "face" part of the header
(i.e. the segments with the text on) do not...
Very strange!
Here's how I'm creating the header:
hwndHeader = CreateWindowEx(0, WC_HEADER, 0,
WS_VISIBLE|WS_CHILD|
HDS_BUTTONS | HDS_HORZ | CCS_TOP |
HDS_DRAGDROP |
HDS_FULLDRAG,
0,15,200,10,
hwndParent,
0,GetModuleHandle(0),0 );
Looks pretty normal to me..
There's got to be *some* way to do this!

uh, i downloaded the DirectX 8 SDK and installed it with the MSVC++ samples. When i opened a sample in VC and i set it to release and compiled i got something about 48kb. After that i followed this tutorial which explained how to build a basic DirectX project (http://www.openrpgs.com/dx_tutorial/dx_toc.html).
When i compiled this it was about 158kb in release. Now my question is:
how come its smaller?? i want to keep my apps as small as possible obviously and it seems that there's a difference in the projects somewhere, maybe in the options, linkage or whatever, i couldn't find out. Does anyone know what makes this rather large difference??

If your project have a couple of resoureces like bitmaps, the exe will be more large than the other....

Well you see, thats the odd thing about it. The directX SDK sample has a bitmap and an icon in it but the project i compiled following the tutorial doesn't have ANY resources so its supposed to be smaller!!! but its not!! its more than 3 times larger, it has to do something with the options or includes or something but i cant firgure out what...

Hi,
i have this problem I have declared an arrayLIst in Managed c++ and i have inserted all the values there but now i Cann't get the values out again . The Values that i have inserted are some objects. i used getEnumerator function to access the ArrayList but it's telling me that can not convert a type System::object to "my Object".
what am I doing wrong?
is there another list type structer in managed C++?
thank in advance for your help and time ,

Hi, I have a MDI MFC application and I would like to tell it to create a new empty document (basically the same as going to File->New). Can anyone tell me what the function call is to do this?
Thanks!

The Framework calls OnNewDocument() so unless calling this function directly asserts (I've never tried it) that should work.

If you can get a pointer to the document template you can call:
pDocTemplate->OpenDocumentFile(NULL) ;
Doc templates can be got through the m_pDocManager pointer of the CWinApp object. You need to iterate it using a POSITION object. Or, if you have an existing document object of the type you want to create, you can call GetDocTemplate() on your document object to get a pointer to it.

I am trying to color the square box of the check button control.
I have had no luck finding code to do it. I would appreciate any help.

You could use DrawFrameControl() or Draw3dRect().

Can you give me some sample code if you have it.
I wasn't succesful using DrawFrameControl function.
thanks.

Hi
I've often seen programs (in most cases c programs) that use one or more of the following operators:
<<, >>
It is called bit-shifting. I saw an ID3-tagger program that uses this commands as well.
Now my question:
What does "bit-shifting" actually do and what is it good for?
Any articles or explanation is greatly appreciated
regards
Gregor

it shifts the bits to the left (<< ) or the right (>>).
if you have a BYTE x equal to 4, it looks like this in binary: 00000100. if you shift this to the left 2 bits, you get 00010000 (16).
it's used when you need to get at the individual bits in a value. i use it all the time in image processing when the size of the pixels is not an even multiple of 8 (like in a 1 or 4 bits per pixel image).

It actually shifts the bits in the number. It is sometimes used for quick multiplication or division. Here are some examples :
<br />
<br />
int x = 5 << 3;<br />
<br />
in binary, 5 is 00000101<br />
shifted left 3 is 00101000<br />
<br />
This has the effect multiplying by 8.<br />
<br />
Another one :<br />
<br />
int y = 40 >> 3;<br />
<br />
in binary 40 is 00101000<br />
shifted right 2 is 00000101<br />
<br />
This is dividing by 8<br />
<br />

Erm, well, could you please explain what bit-shifting is used for in this case:
fprintf( outfile, "%d.%d.%d.%d:%hu\n",
(ipaddr>>24)&0xff, (ipaddr>>16)&0xff,
(ipaddr>>8)&0xff, ipaddr&0xff, port);
This is a code snippet of a tool that queries server and displays there IPs. This is actually what the above code does.
But I have no idea what it really does 
maybe you could explain to me
idaddr is declared as
unsigned int ipaddr= ntohl(server->ipaddr);
And one last question:
How do I make keywords appear in red color in this message board?

An unsigned int consists of 32 bits, so you can see it as a packed array of 8-bit values --precisely what one needs to store a numeric IP address a.b.c.d. ipaddr&0xFF (or-ing with the binary number 0000 0000 0000 1111) yields the value of d. Shifting the appropriate number of bits and repeating the or-ing trick yields th remaining values.

This will split your 4-byte number ipaddr into individual bytes and print them.
