Hello everybody,
i have a problem with the OnEnable method : once it is used, the normal
display of the CWnd item doesn't work well (not fully grayed if disabled). A
possible workaround is the call the CWnd::RedrawWindow() inside the OnEnable
method, but it works only with VC++8, and i developp with VC++7.
Does anyone of you have a fix for this problem with VC++7 ?
Thanks

What is that "CWnd item" which "doesn't work well"? A control?
Did you call the base class OnEnable method, like for example:
void CMyButton::OnEnable(BOOL bEnable)
{
CButton::OnEnable(bEnable);
}

Hello,
you are right, to get the default enabling/disabling behavior of the CWnd, i have to call the base class method. I thought that the OnEnable method was just an empty shell provided by the MFC framework to put some extra code, but i was wrong. It really does some process.
So thank you for your help, my problem is solved

It just calls the default window procedure which does its job:
_AFXWIN_INLINE void CWnd::OnEnable(BOOL)
{ Default(); }
LRESULT CWnd::Default()
{
_AFX_THREAD_STATE* pThreadState = _afxThreadState.GetData();
return DefWindowProc(pThreadState->m_lastSentMsg.message,
pThreadState->m_lastSentMsg.wParam, pThreadState->m_lastSentMsg.lParam);
}
You are welcome!

it's a colorful icon or say it's 256 colors;
I want to load this icon to be a gray one!
is it existing a way to load ?
or it's impossible, on the other hand ,we shall prepare a gray one !
can it to be a gray one?
if it will do, how I load it?
waiting for answers!
Just my interest for these common things

If you want a monochrome icon then no sweat.
Call ::LoadImage and pass LR_MONOCHROME as load option.
HICON hIcon = (HICON)::LoadImage(AfxGetResourceHandle(),
MAKEINTRESOURCE(IDI_ICO_256COLOR),
IMAGE_ICON,
0, 0,
LR_MONOCHROME);
If you want a grayscale one, better is to "prepare" it yourself. There are tools that convert color icons to grayscale and Irfan View[^]is a free one.
Import the gray icon in your project resources, then load it like any others.

Hello !
Who can tell me how to distinguish the following case:
case1: Prog.exe is started by double click.
case2: Prog.exe is started by operating system.
case3: prog.exe is started by other program.(for example： ShellExecute())
Distinguish means in the prog, to distinguish.
Thanks!

It's a very interesting question, but I'm not sure there is a way. Just for curiosity, why do you want to distinguish them?
Best,

, the requirement is that:
There is a program (let's name it A.exe), if user double click the A.exe, it doesn't reponse, by other words, user can't start it by double click.
But the A.exe can be started by another program B.exe, and
after user setting, the A.exe can start when the user log in the system(XP or vista).
Best Regards,

I'm not quite clear about this requirement:

If you require prog.exe to be started with a parameter, you'll foil all double click attempts. For instance, "prog.exe" just terminates, but "prog.exe /run" makes it run.

Hi guys, I've got a quick question.
I have the Borland 5.5 C++ compiler and in order to compile standard C++ code, you type 'BCC32 filename.cpp' in the command screen to compile "filename".
In order to compile a Visual C++ application, you need to add a parameter or setting to that command.
My question is which one is it? I've done it before so I know how it's done, but I've forgotten the exact line and I can't seem to find it on the huge place we call the internet.
Thanks for answering such a stupid question in advance!

cl /EHsc sample.cpp

Hmm
That doesn't seem to work.
"cl" is not recognised as being an application, command or batchfile and I'm positive that what I'm referring to was this:
<br />
"BCC32" line "sample.cpp"<br />
with "line" being the extra line which I have forgotten. I think there was a "-" preceding the line, but I'm not sure.
QUite frustrating to have forgotten the line, but my copmiler won't compile a Visual C++ app without the little line.
Thanks for your help anyways!

You have to run vcvars32.bat to initialize those environment settings before your invoking CL.exe command.
From MSDN Library:
The vcvars32.bat file sets the appropriate environment variables to enable 32-bit command-line builds.

Usually, when you have an image or object embedded in a richtext document you can interact with it like editing or resizing.  Is there anyone who knows how to disable user interaction with these objects?
Thanks,

Have you seen MS KB article 178893 ("HOWTO: Terminate an pplication "Cleanly" in Win32")?

Thank you for your replay, please tell me where can I get the article,"MS KB" means what?

Microsoft has recently changed the way to do that, or at least it has been changed temporarily.
So the way to do it at the moment is to go to the Advanced Search and put the article id in the "For" box and select "Article Id" in the "Search Type" box.
