Yeah, I think next year I'll plan to go a month early, if Maiden do Ozzfest again. Now that Ozzy won't do it, I reckon they'll need Maiden AND Priest to make it worthwhile.

It's not that unusual really. I think that's the mother of invention.
If you worked for me and I paid you $37 an hour to work for me regardless of what you did and I said Christian, "See if you can write a program that will all a MAC user to execute Win32 code in a runtime simulated enironment on MAC's."
You would probably say, "WTF! I've got more questions." You'd get a few more answers but since your pay is the same regardless you'd probably go out and dig away right? I know I would. Give me a job to do something I've never done before you and just got my complete attention. I hate doing things I know how to do it's boring.
Having said all of this I'm probably a bit farther along than the person in this post but hey... I was more making a remark to your question and I think I at least am glad that supervisors do this. It's probably how I got a 3.4 gig hyperthreading processor on my desktop that runs cool enough to not burn down my house or fry eggs in 11 minutes.

Sure - but that's a long way from giving people with obviously very little experience in general that sort of opportunity. There's some basic coding skill that needs to be taught, or at least learned.

I'm glad that it happens at my level of experience. But when people ask questions on a more basic level, it worries me.

You are completely right of course. I was being a lot more general. When you narrow the scope like that you are exactly right in that context.
The major flaw in all my arguments is that known genius's tend to be the inventors and everyone else just winds up with a head ache and a pay-cut. Or they got smart and learned to use Google and communities.

Hi, is there a function or message that is sent to a Childframe or view when it becomes active? In other words, I have a few MDI documents open and would like to be notified when the user selects one (it becomes the view that gets focus), or if one of the child's views becomes the active one. I need to know when the user selects between these views when they are selected, but not simply which one is the active view at any given time.
Thanks!

Too freaking simple!  Thank you for the direction. I needed to tweak it a bit, but it is perfect!
LRESULT CWinCTestFrame::OnActivate(WPARAM wParam, LPARAM lParam)<br />
{<br />
<br />
if(((HANDLE) wParam == this->m_hWnd) && (IsWindowVisible()))<br />
TRACE("ChildFrame - I'm Activated!\n");<br />
<br />
return 0L;<br />
}<br />

Hmm... Since you are using MFC, a simpler approach would be as follows:
In your class declaration :
afx_msg void OnMDIActivate(BOOL bActivate, CWnd* pActivateWnd, CWnd* pDeactivateWnd);
In your class implementation file:
BEGIN_MESSAGE_MAP(CWinCTestFrame, [baseClass])
ON_WM_MDIACTIVATE()
.
.
.
END_MESSAGE_MAP()
void CWinCTestFrame::OnMDIActivate(BOOL bActivate, CWnd* pActivateWnd, CWnd* pDeactivateWnd)
{
CMultiFrame_base::OnMDIActivate(bActivate, pActivateWnd, pDeactivateWnd);
if (bActivate)
TRACE("ChildFrame - I'm Activated!\n");();
}
bActivate will be TRUE or FALSE, depending on whether the child is being activated or deactivated, while pActivateWnd and pDeactivateWnd will point to the child being activated or deactivated, respectively.
More details at MSDN[^]
BTW, I don't think the call to IsWindowVisible() in your code is making any difference; 'visible' is not the same as 'active'.

Thanks again! Your suggestion also looks cleaner and I'll do it the way you suggested.

Yes, that's true, but in my application, when the view becomes 'active' it sends a message to the mainframe to trigger further action (it's a long story  ). The IsVisible call prevents the childframe from sending that message to the mainframe when the child is being closed.
Once again, thank you for your help and responses!

Hi, all
I need to Put a Break Point in MFC source file DLGDATA.CPP, but while I am in my own application, how could I do that?
the reason I need set breakpoint is I have those warning:
Warning: skipping non-radio button in group.
thanks
|

Hi,
just open the DLGDATA.CPP in your \Microsoft Visual Studio\VC98\MFC\SRC\ folder
and set your breakpoint by using the context menu.
I tried it in
HWND CDataExchange::PrepareCtrl(int nIDC)
and it worked, but I think this code shouldn't be too buggy...
Regards

To eliminate the warning, you need to do the following:
1) Edit your dialog template and make sure every radio button group has all its individual radio buttons in consecutive tab order
2) Make sure the first radio button in each radio button group has the group style
3) Make sure every other radio button in the same group has not the group style
4) The first control after (in tab order) the last radio button in a group has the group style (if the last radio button in a group is also the last control in the dialog, set the group style to the first control)
After doing this, you'll have not only eliminated the warning, but also made sure your buttons will behave as expected (i.e.: you can navigate them in proper order using the tab key, and clicking one of them will deselect whichever one was selected in that group).
Hope that helps,

it was the #4, I check the group for the "The first control after (in tab order) the last radio button"...
okay, the last radio button is 13, the 14 is also in the group with 13, means I need to check 15 for the group, right? is 15 "The first control after (in tab order) the last radio button"?
after this, I still have a "Warning: dialog data checkbox value (40) out of range.".......you must know this one, too.....
thank you very much!

Assuming 13, 14 and 15 is the tab order, then yes, that's right.

That's a different problem.
This is the code in MFC's dlgdata.cpp (VC 6.0):
void AFXAPI DDX_Check(CDataExchange* pDX, int nIDC, int& value)
{
HWND hWndCtrl = pDX->PrepareCtrl(nIDC);
if (pDX->m_bSaveAndValidate)
{
value = (int)::SendMessage(hWndCtrl, BM_GETCHECK, 0, 0L);
ASSERT(value >= 0 && value <= 2);
}
else
{
if (value < 0 || value > 2)
{
TRACE1("Warning: dialog data checkbox value (%d) out of range.\n",
value);
value = 0;
}
::SendMessage(hWndCtrl, BM_SETCHECK, (WPARAM)value, 0L);
}
}
As you can see, the warning is shown because the variable associated with a checkbox control has a value (40), which is not in the expected range (0..2) for a checkbox.

Dear Experts,
I need to compile an old project (built with VC++) in Visual Studio .Net
2003.
The project is going to build a DLL. When i try to compile the project, i
got the following errors:
c:\thepath\aaa.cpp(890): error C2065: 'm_nBackStyle' : undeclared identifier
c:\thepath\aaa.cpp(890): error C3861: 'm_nBackStyle': identifier not found,
even with argument-dependent lookup
c:\thepath\aaa.cpp(891): error C3861: 'm_nBackStyle': identifier not found,
even with argument-dependent lookup
c:\thepath\aaa.cpp(892): error C3861: 'm_nBackStyle': identifier not found,
even with argument-dependent lookup
in aaa.cpp, 'm_nBackStyle' are used as the following:
// Set up background mode.
890: if(m_nBackStyle != 1 && m_nBackStyle != 2)
891: m_nBackStyle = 2;
892: SetBkMode(di.hdcDraw, m_nBackStyle);
in aaa.h, i have:
#include <atlctl.h>
and aaa.h is already included in aaa.cpp.
I found the following declaration in ddd.h, which is in another project (the
solution has sevreal projects):
LONG m_nBackStyle;
Is it because my project is not set correctly? When i tried to open it in
Visual Studio .Net 2003, i was asked to transfer the project, i wonder if
after the transfer, the dependence relationship of the projects was lost.
I found some info about m_nBackStyle at:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceatl/htm/cccontrl_72.asp
Could you please help me fix the problem.
Thanks!

You're joking right ? Your files are called aaa.h and ddd.h ?
If you check 'Do not treat <'s as HTML tags' then we can see what your include was.
That link refers to the pocket PC sdk's, is this a pocket PC app ?

Hi Christian,
Thanks for your note.
I just wanted to explain my problem clearly, so i used a simple note for my files (as used aaa.h and ddd.h), it did not mean my file was exactly named in that way.
i am working on a Desktop computer.
Hope you can give me some suggestion to solve the problem.
Your help is highly appreciated!!!
Thanks!

Interestingly, when I search the include folder on VC2003, I can't find m_nBackStyle. The VC6 atlctl.h contains it. However, unless your class is derived from CComControlBase, it doesn't matter, it wouldn't be able to see it. Is this your base class ? I guess so, from the include in your header file. It looks to me like this base class has changed a lot, so I reckon you've got your work cut out for you.

--------------------------------
Hi Christian,
Thanks a lot!
You are right, m_nBackStyle is in atlctl.h.
Please see the info about m_nBackStyle at:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceatl/htm/cccontrl_72.asp
m_nBackStyle is defined in ddd.h, in another class, in another project, in the same solution. There are several projects in the same solution.
If it is because the projects dependence info was lost after i transfer the projects to VS .NET, how can i figure out the dependence relationship between the projects and recover that quickly?
Thanks for your valuable suggestion!
Vic
