Either that or maybe write a preprocessor-like app whose sole job is to inspect an environment variable and update a #define in a global header file. The advantage being that you would still be able to use the normal VS/VC make. I don't know how to inject a processor into the mix, but I'm sure that it can be done.

That sonud like a nicer soultion.
I'll will try and fine some pre-compile place where i can hook the thingy in.

Actually, thinking more about it now. You would think that writing an add-in that does what I'm proposing here (updating a global file's #define) and then using the VS object model to kick off the build. THat would give you the best of both worlds (an add-in vs a preproccesor) and would be a solution that is already documented (the writing of add-ins). I would think that that would be easier than finding dox on preprocessing. What do you think?

I agree that that sounds like the most elegant solution.
However for now im just looking for the fastest way to get it
working and that way would require me to dig in to DevStudio add-in writing.
I'll probably will do it the 'proper' way when i got some more time over.

I hear you, mate. Unfortunately deadlines often get in the way of the cool stuff we want to write

If you are using DevStudio I can see two possible ways:
1) VB Macro. They are simple to write but I don't know if VB has the methods needed to read the environment. There is an object to control the build, the BuildProject object.
2) Developer Studio Add-In. This is a compiled .dll so I you could do anything here that C/C++ allows you to do. Problem is they are more complex to write then a macro. But there are some nice examples on CodeProject.
Good luck,
David

That might be a way to do it.
If VB dont have the requried methods thay can easily be added trough a COM object
I'll ponder on the options for a while.

(smack forehead) DOH! Much better than my recommended way. An add-in or macro would be the best way to do it. Nice suggestion!

Do you mean :
int num = 3;
if(num == 5)
#define _A
#undef _B
{ }
else
#define _B
#undef _A
{ }
#if defined(_A)
cout << "_A defined.\n";
#endif
#if defined(_B)
cout << "_B defined.\n";
#endif
The result is :
_B defined.

Has anyone tried using this function? It wants seconds for the new timeout value but everything I throw at it fails. Or I should say returns "0", which is supposed to be failed. I even tried the default value of 120 without luck.
It does seem to do something to the timeout - makes it about 5 minutes regardeless of what value I set.
I'm testing on W2K Workstation Professional SP2.
Thanks,
David

Can someone help me with the code necessary to update the HKEY LOCAL MACHINE | SOFTWARE | Microsoft | Windows | CurrentVersion | RunOnce registry key?

There are seveal registry classes on CodeProject. Do they not do what you need?

I have been exploring this for hours. The one by PJ Naughter seems the most promising but I haven't been able to figure out how to get it to update any of the keys except the one he wrote for his company. What he wrote looks great. I'm just struggling because I can't get it to work for me. The problem is me and that is why I asked for help.

I have a much simpler CRegistry class that has always worked for me. If you want, I'll send it to you.

I want to overwrite the OnDraw of my ATL composite control, to prevent flickering when redrawing. I thought I could just overwrite the CComCompositeControl::OnDraw, but it seems this method is never called, instead the OnPaint of CAxHostWindow is called, which does not call the OnDraw as the OnPaint of the CCompositeControl does.
Anyone got an idea how to do this ???

Hello,
I have a little question!
I have a CEdit-derive class, we shall tell CMyEdit.
Inside it on pressing the left button of the mouse I create in-place edit, we shall name CInPlaceEdit
pEdit = new <code>CInPlaceEdit</code>;
pEdit->Create(WS_CHILD | WS_VISIBLE | ES_CENTER, rect, this, 100);
Then, when CInPlaceEdit loses focus, it needs to be removed.
Where and as it is better to remove him!?
Best regards,
Eugene Pustovoyt

DestroyWindows should do the trick

If I have correctly understood, I should in CInPlaceEdit in method OnKillFocus call DestroyWindow?
This same that in the parent to specify delete pEdit?
Or in DestrowWindow it is necessary to specify
delete this;
Best regards,
Eugene Pustovoyt

If you look at the CWnd d'tor, you'll see that it calls DestroyWindow for you (shown here) so you can do the "delete this" if you want and it will work.
CWnd:: ~CWnd()
{
if (m_hWnd != NULL &&
this != (CWnd*)&wndTop && this != (CWnd*)&wndBottom &&
this != (CWnd*)&wndTopMost && this != (CWnd*)&wndNoTopMost)
{
TRACE(traceAppMsg, 0, _T("Warning: calling DestroyWindow in CWnd:: ~CWnd; ")
_T("OnDestroy or PostNcDestroy in derived class will not be called.\n"));
DestroyWindow();
}
...
}

Thank you!
But I have some more questions, there can be you help to me, before I shall create a new theme!?
1. Why in-place edit I can't change the background color?
CInPlaceEdit::OnCtlColor()
{
HBRUSH hbr = (HBRUSH)m_brColorBk;
pDC->SetColorBk(m_crColorBk);
return hbr;
}
2. How to delete in-place edit, when the mouse clicked outside the parent window?
Best regards,
Eugene Pustovoyt

1) You're handling the wrong message. You need the following:
.h file
afx_msg HBRUSH CtlColor(CDC* pDC, UINT nCtlColor);
.cpp file
BEGIN_MESSAGE_MAP(CMyEdit, CEdit)
ON_WM_CTLCOLOR_REFLECT()
END_MESSAGE_MAP()
...
HBRUSH CMyEdit::CtlColor(CDC* pDC, UINT nCtlColor)
{
pDC->SetBkColor(RGB(255,0,0));
return m_Brush;
}
2) Do the "delete this" in the control class' OnKillFocus
