Anything in Windows that there's not a documented interface for, you can usually accomplish through Windows subclassing.
In your case, to sketch out a solution, you would subclass the list control window, and then handle in all liklihood WM_PAINT. On that message, you would send LVM_GETITEMRECT to the list control window, and get the bounding rect of the list control cell you were interested in. Then just BitBlt whatever color you want to the hdc of the window, using the dimensions of the rect you retrieved (possibly using PATBLT for a ROP code, first setting the hdc brush to the appropriate color.) So that's the basic idea.
Actually, although I'm not sure I entirely understood you, the above solution might not work if you BitBlt to the cell and then the original WinProc writes text over it, as the textbackground color may be wrong, unless its being drawn transparent. Of course, there's SetBkMode to make the text background transparent, but I don't know how you get this to work for the hdc the original WndProc is writing to. It looks like you've got some work to do on your own, but its certainly not impossible. Also there's LVM_SETTEXTBKCOLOR, FWIW.

LVS_OWNERDRAWFIXED the list-view control sends a WM_DRAWITEM message to paint eachitem

do an article search for lvs_ownerdrawfixed. there are two that look particularly interesting to solve your dilemma, one by Muhammad Azam[^] and one by Piotr Szewczyk[^]

If you mean with color the item-selection and that only the current listtrl has a selection... you can play with the KillFocus to unselect the item/subitem when changing of ListCtrl. You should have no colors on any unselected ListCtrl.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you

I am familiar with win32 app development, c, masm, and some kernel knowledge(mainly from the book "programming applications for ms windows" by Jeffrey Richtie).
Who could give me some suggestions? Thanks a lot.

Finding a good single resource for learning drivers is very tough. It can be a complex subject, and requires a lot more knowledge of how the OS works than app level programming.
Here's the usual list that is given on other forums when the question arises.
The WDK itself - documentation andthe samples are improving but it assumes you already have a good knowledge of the OS
"Programming the Windows Driver Model" 2nd ed by Walter Oney - make sure it is the 2nd edition
"Microsoft Windows Internals, Fourth Edition: Microsoft Windows
Server(TM) 2003, Windows XP, and Windows 2000" by Mark Russinovich and David Solomon
"Windows NT Device Driver Development" by Peter Viscarola and Tony Mason - dated but the stuff they discuss hasn't changed and it's a good foundation.
"Developing Drivers with the Windows® Driver Foundation" by Penny Orwick and Guy Smith - this one is from Microsoft Press and is the only book currently published with a good description of KMDF
This one should be excellent (if they ever get it published) "Introduction to the Windows Driver Foundation Kernel Mode Driver Framework " by Peter Viscarola, Tony Mason, Mark Cariddi, Brenda Ryan, Scott Noone, and OSR

But some times I faced very unusual problem,
I installed my application then rebooted my system After rebooting my all MFC exes of my application get deleted from my hard disk.
Please help me for solving this issue.

Viruses!, because Windows didn't delete anything,till it instructed too.. you can also check Installer, might be somebody have play a prank on you.. MoveFileEx is famouse for playing prank with people. as it delete the file at reboot, if you use proper flags!

Hello,
I have a question about callback function.
My code is waveInOpen(&hWav,0, &wfx,WaveInCallback ,0, CALLBACK_FUNCTION);
But it comes some problems, the error message is
error C3867: 'p2p::Form1::WaveInCallback': function call missing argument list; use '&p2p::Form1::WaveInCallback' to create a pointer to member
I dont realize what happened.
Can anybody solve this question for me?

This error happens when you tried to take the address of a member function without qualifying the member function with its class name and the address-of operator.
Can you show the callback function declaration?
- NS -
|
|
|
|

OK.
void CALLBACK WaveInCallback(HWAVEIN hw, UINT uMsg,
DWORD_PTR dwInstance, DWORD_PTR dwParam1, DWORD dwParam2)
{
waveInAddBuffer(hw, (WAVEHDR*)dwParam1, sizeof(WAVEHDR));
}
I create it in the From.h.
But I don't know where to allocate it.

Isn't it a static function? AFAIK it should be static function.
Also I found a mismatch with the documentation in MSDN. See...
void CALLBACK waveInProc(
HWAVEIN hwi,
UINT uMsg,
DWORD dwInstance,
DWORD dwParam1,
DWORD dwParam2
);
You are using DWORD_PTR instead of DWORD. But I am not sure about this

Appreciate for ur reply.
But it's still same.

Try to cast like
waveInOpen(&hWav,0, &wfx,(DWORD_PTR)WaveInCallback ,0, CALLBACK_FUNCTION);

|

It comes other errors.@@
1.error C3374: can't take address of 'p2p::Form1::WaveInCallback' unless creating delegate instance
2.error C2440: 'type cast' : cannot convert from 'void (__clrcall p2p::Form1::* )(HWAVEIN,UINT,DWORD_PTR,DWORD_PTR,DWORD)' to 'DWORD_PTR'

Please show me the declaration of the callback function. Not in the cpp but inside the class in header file.

It's declared in mmsystem.h:
void CALLBACK waveInProc(
HWAVEIN hwi,
UINT uMsg,
DWORD dwInstance,
DWORD dwParam1,
DWORD dwParam2
);

public ref class Form1 : public System::Windows::Forms::Form

int call_id;

I put in the class form1

You very certainly wanted to ask that in the "Managed C++"-Forum?!?
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

I agree ask on the correct forum.

I am not sure about this coding.
In C++, it should be static declaration. Try to make it static function.
