That's it. So, as each instance of MyClass has a separate instance of objectMutex, you can access different instances of MyClass concurrently on separate threads, but not the same instance (because the mutex will stop you).

Hello,
Does anyone know of a way to disable the "What's This?" menu (appears after right-clicking on certain items)? I would like to disable it on my "Save As" dialog. I've created a class for the dialog and it is inherited from the CFileDialog class. I have looked at many places on the internet, but I'm unable to find what I need. Any ideas on this would be appreciated.
Regards,
Mike

Sounds like you need to remove the WS_EX_CONTEXTHELP style.

In the OnInitDialog function of my class derived from CFileDialog, I have the following:
GetParent ()->ModifyStyleEx(WS_EX_CONTEXTHELP, 0);
The only difference I noticed was that the question mark button, which is normally located to the left of the close button (the X), disappeared. The What's This? is still showing.

I guess I misunderstood what you were after. I do not know of a way of removing that little context menu. I guess you could try hooking the Save As dialog and then intercepting the right-click message.

Just out of curiosity, why derive a class from CFileDialog rather than just create an instance of it?
UINT_PTR CALLBACK OFNHookProc( HWND hdlg, UINT uiMsg, WPARAM wParam, LPARAM lParam )
{
return 0 or 1;
}
CFileDialog fd(FALSE, 0, 0,
OFN_ENABLEHOOK | OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_LONGNAMES | OFN_OVERWRITEPROMPT | OFN_CREATEPROMPT);
fd.m_ofn.lpfnHook = OFNHookProc;
fd.DoModal();

The application I'm working with uses a CFileDialog format, except for 2 buttons that have been added to the dialog. This is the reason for deriving from CFileDialog.
Anyway, after trying your code, I'm still seeing the "What's This?" menu. When I debug your code, and set a breakpoint in OFNHookProc, the breakpoint is reached several times, but is never reached when I click on a button using the secondary mouse button. When I click on a button using the secondary mouse button, the "What's This?" menu appears. I tried both return values (0 and 1 from function OFNHookProc) with no success.
Regards,
Mike

I simply provided you a starting point. You'll need to do some research in order to fill in the blanks. There are no guarantees that this will work, but at least you'll have found one more way that doesn't. You can use Spy++ to see the relationships of that dialog. The hook procedure is actually for the child dialog of the main dialog. You can even customize the child dialog by providing your own template.

OK, thank you for your time and effort. Hopefully, I'll be able to figure out how Spy++ works by doing my own research.

Hello.
First of all, have you read this[^] yet? If no, do it now, if yes, you should know by now that if you don't ask specific questions then you are not likely to get usefull answers. Noone will tell you here how to write an application that will perform what you want. Try to do it and when you get stuck with it, come here and ask, "i did this and that and this and that happens, any ideas why and how to do it right?" instead of "Hey, i want to write a program, so tell me how.". Good luck with your project.

I use a window with horicontal+vertical ruler from COXRuler and COXRulerOrganizer class (Ultimate Toolbox).
Both start in the left upper corner with the origin. The values on the horicontal ruler grows from left to right. I need a possiblity to change the origin from the horicontal ruler to the right side, so that the values grows from right to left.
It would be a great help for me, if there is somebody with more experience or an idea for a workaround.

I'm trying to take an existing class and add a member function to it. Something like this:
class baseclass {
public:
baseclass();
baseclass(int i);
~baseclass();
public:
int a() {
int b() {
}
class derived : public baseclass {
public:
derived() : base();
derived(int i) : base(i);
public:
int sum() { return baseclass->a() + baseclass->b(); };
}I know I have to explicitly declare the constructors, but I'm under the impression that a() and b() are inherited without further effort. Which means if I create an object derived d, then int i = d.a(); is a valid expression.
Do I have to "explicitly inherit" a() and b() in order to use them in sum() ?
I've been all over the documentation and the articles here, but can't seem to track this down.
More nooB questions, I know - any help is appreciated.

no need to any further steps. as you've publically inherited from base class, the public and protected attributes and functions are part of derived class.
<blockquote class="FQ"><div class="FQA">Mike the Red wrote:</div>int sum() { return baseclass->a() + baseclass->b(); }; // I DO know it's not done like this...</blockquote>
It should be
int sum() { return baseclass::a() + baseclass::b(); };
is it really not possible for you to call d.a()? what's the problem you're facing?

What's wrong with:
class baseclass
{
public:
baseclass(){}
baseclass(int i){}
~baseclass(){}
public:
int a() {return 1;}
int b() {return 2;}
};
class derived : public baseclass
{
public:
derived(){}
derived(int i):baseclass(i){}
public:
int sum()
{
return a() + b();
}
};

Hi
I created a CWnd derived class.
pPreviewWindow = new CMyWindow(this, bitmap);
CRect rc;
pStatic->GetWindowRect(rc);
pPreviewWindow->Create("", "", WS_CHILD| WS_VISIBLE, CRect(rc.left,rc.top,rc.bottom,rc.right), this, 1234);
....
pPreviewWindow->Invalidate();
The "Invalidate" (and other functions) will cause ASSERT(::IsWindow(m_hWnd))" fails.
How can I resolve it?
Best regards,

Have you checked that Create() was successful?

Hi
I just checked the Create return value. It is "0". Why would this happen?
I created this class using VS2005 class creation wizard. It looks like:
class CBitmapWindow : public CWnd
{
DECLARE_DYNAMIC(CBitmapWindow)
public:
CBitmapWindow();
CBitmapWindow(CWnd* pParent, HBITMAP hBitmapIn);
virtual ~CBitmapWindow();
protected:
DECLARE_MESSAGE_MAP()
public:
afx_msg void OnPaint();
};
pPreviewWindow = new CBitmapWindow(this, pCompatDev->GetBitmap());
BOOL ret = pPreviewWindow->Create("wert", "wert", WS_CHILD| WS_VISIBLE, CRect(rc.left,rc.top,rc.bottom,rc.right), this, 1234);
---------------------------------------
I just checked create format:
virtual BOOL Create(
LPCTSTR lpszClassName,
LPCTSTR lpszWindowName,
DWORD dwStyle,
const RECT& rect,
CWnd* pParentWnd,
UINT nID,
CCreateContext* pContext = NULL
);
Must I give "UINT nID" a number or not? If I have no ID number, what should I input here?
Best regards,

You've to pass a valid class name to the Create function.
Either you can pass some standard window class[^] names
or register your own class name using AfxRegisterWndClass function and pass the name to the Create function

Where can I find them ? I want to go back in time and have on my hand those tools even if I can get them on a virtual machine.
Can you help me fulfill that wish ?
