CreateDialogInd irect() fires my Radio button click function without the radio
button having being clicked. I am using VC++ 2003.NET. I believe this is yet
another Microsoft bug. Have checked dialog resources and memory - both appear
to be in order. Can anyone comment on this? Should CreateDialogInd irect()
which is located in dlgcore.cpp ever fire a button click routine??

Hmm. Usually bugs in the o/s affect thousands of developers / users. And
when they do, there is usually a knowledge base article or other discussion
of it easiliy retrievable with a Google search. I just looked and found
nothing.
I'm not saying there isn't one (I don't have enough information to make that

You are mistaken to think the way you do. I have found hundreds of bugs in
Microsoft products and I am not so sure these affect thousands of developers.
Let's see if I can clarify this a bit more:

I have no interest in debugging Microsoft products. In fact I have already
found a workaround but I will prove to you that this is a bug. I am an expert
assembly language programmer.
Let's see if I can clarify this a bit more:
CreateDialogInd irect is really a macro that wraps the
CreateDialogInd irectParam() function.
When I set a break point and disassembled the code, the following is what I
got:
hWnd = ::CreateDialogI ndirect(hInst, lpDialogTemplat e,
pParentWnd->GetSafeHwnd( ), AfxDlgProc);
7C2364D0 mov ecx,dword ptr [pParentWnd]
7C2364D3 call CWnd::GetSafeHw nd (7C28E080h)
7C2364D8 mov dword ptr [ebp-94h],eax
7C2364DE push 0
7C2364E0 push offset AfxDlgProc (7C235B30h)
7C2364E5 mov edx,dword ptr [ebp-94h]
7C2364EB push edx
7C2364EC mov eax,dword ptr [lpDialogTemplat e]
7C2364EF push eax
7C2364F0 mov ecx,dword ptr [hInst]
7C2364F3 push ecx
7C2364F4 call dword ptr [__imp__CreateDi alogIndirectPar amA@20
(7C141A98h)]
7C2364FA mov dword ptr [hWnd],eax
Notice the call to CreateDialofInd irectParam - my radio button click
function is fired from this call. There is nothing to wonder about here my
friend. This function should not be firing any button click functions.
Incidentally, it only fires one radio button click function and there are
more on that dialog.

Information for you to try and replicate the problem:
I am using MDI to create a view with a tab control. One of the tabs is the
home of several radio check buttons. All the radio check buttons have
click-event routines.
The function I referred to below only fires the first in the series of these
dialog radio buttons.

I just checked an application of mine (~50K lines of Win32 C code) in which

I see no spurrious button clicks.

My first response is always to check my code for errors. I have been a
programmer over 20 years so I don't rush to conclusions and usually I am not
wrong. This is often perceived as arrogance but it is not - only quiet
confidence.
Look, this is not an assertion as you claim. Do you agree that the
CreateDialogInd irectParm() function should not fire click events? If you
answer yes to this, then there is a bug.
As I said, this function is called for a dialog box that is attached to a
Tab Control that is attached to 1 of 3 panes in a view. On this dialog box
there are only radio check buttons and all of them have a button click
routine.
I am using XP/SP1. But this makes no difference. I traced the call in
assembly right up to the point where my click routine is called. To me this
is solid proof that the CreateDialogInd irectParm function is firing my click
routine.

As I said, it does not prove your assertion. You say CreateDialogInd irect()
is buggy in your experience. I say it is not in mine. What does that prove?
Absolutely nothing.
Further, there are a number of things that happen as a result of the call to
CreateDialogInd irect() and indeed happen _before_ it returns. For example,
more than a couple of messages are directed at the window as a result of the
call. The application's handler for any of them, or a handler in a base
class if you are using MFC or some such could be the source of your problem.

Not sure it applies, but radio buttons are documented to fire a BN_CLICKED
notification when they get a WM_SETFOCUS.
