Create the menu, open dialog template in the resource editor and select menu from dropdown list on 'General' page.

or you can create the menu manually and call SetMenu() from within the dialogs OnInitDialog() handler.
this is useful if you intend to dynamically modify the top level menu items.
ps. whenever you call SetMenu(), msdn says you must follow up with a call to DrawMenuBar()

I use internet sdk function to write a multi-threads program.
But I find only two or three threads can download http data,other threads is waitting.I want to know what limit the max download threads?The server or the client?
Hi
|
|
|

To the best of my knowledge, it is the bandwidth of your connection that is limiting the number of threads that are able to download data (actually, all of them are trying, so you can expect all the threads to complete their operations as the first ones stop consuming bandwidth). To prove this point, try using a server in your own LAN (which will provide much more bandwidth) or even within your local machine.

I am writting some code to add new buttons in a toolbar at runtime.
My problem:
When i create a new button, the toolbar is not big enough and the last one is no visible anymore. If i move the toolbar to another position in the window (manually, with the mouse), it resize itself automatically and all the buttons become visible again.
How to get the toolbar with the right size automatically , just after adding a new button ?
I try adding Invalidate() and AutoResize(), but it doesn't work.
void CMyAppView::OnAddNewModule()
{
CToolBarCtrl* pToolBarCtrl;
pToolBarCtrl = &(((CMainFrame*)GetParentFrame())->GetToolbar())->GetToolBarCtrl();
TBBUTTON tbButton;
tbButton.iBitmap = pToolBarCtrl->AddBitmap(1, IDB_MY_RUNTIME_ID);
tbButton.idCommand = MY_NEW_COMMAND;
tbButton.fsState = TBSTATE_ENABLED;
tbButton.fsStyle = TBSTYLE_BUTTON;
tbButton.dwData = NULL;
tbButton.iString = NULL;
if (tbButton.iBitmap==-1)
TRACE("I couldn't load the button image");
if (!pToolBarCtrl->InsertButton(1, &tbButton))
TRACE("I couldn't create the new button");
pToolBarCtrl->AutoSize();
}Thanks !
PD: I use ON_COMMAND_RANGE handler, to catch the new event with my predefined ID, thanks Saurwein

try calling ((CMainFrame*)GetParentFrame())->RecalcLayout();
i'm not sure that it _will_ work but CFrameWnd uses it alot internally when positioning controlbars.

If we create a shared memory zone with CreateFileMapping(...), we have to close it with UnMapViewOfFile(...) and CloseHandle(...).
My question is this: Is the memory released properly doing just that? Or do I have to take some further action before closing the memory handle?
[VISUAL STUDIO 6.0] [MFC] [WIN98/2]
 Bluute tette!

From MSDN docs on CreateFileMapping:
To fully close a file-mapping object, an application must unmap all mapped views of the file-mapping object by calling UnmapViewOfFile, and close the file-mapping object handle by calling CloseHandle. The order in which these functions are called does not matter. The call to UnmapViewOfFile is necessary because mapped views of a file-mapping object maintain internal open handles to the object, and a file-mapping object will not close until all open handles to it are closed.

Use the OpenService() function of NT.
Use its related functions to manipulate services.
Hope this helps.

Hi,
Can you be a bit more specific.I din't get how to use this OpenService() function of NT for disabling a user account.Please explain it in detail
Thanks,
Abhishek.

In that case, take some time to learn how to use the function 
Look for OpenService documentation in the MSDN - it is not very hard to use.
You are particularly interested in the ChangeServiceConfig.
Hope this helps.

Somebody PLEASE help me!!! 
http://support.microsoft.com/default.aspx?scid=KB;EN-US;q261003&
I found this article but it's incomplete on how to fully implement in my
application. In the example, is "CMyBrowser" an instance of "CHtmlView"?
Because :Exec is not a method of CHtmlView. Can someone
enlighten me on how to implement this code please?
Any assistance would be greatly appreciated.
Best Regards

hello,
i Derived a Class from CWnd named CStarter
and in my Application Class i add the code
CStarter *pStarter ;
pStarter = new CStarter ;
bool bRet = pStarter->Create(NULL,NULL,WS_VISIBLE,CRect(0,0,0,0),NULL,10000) ;
and then there is an asertion popups..!!
and then i changed the argument 5 (HandleTo parent window)
to (CWnd*)GetDesktopWindow() ,then there is no assertion,but the return value is 0..
What is the reason,How i can solve it and create a CWnd here...

I've run across a bit of a problem using exceptions and references. Here is
some test code:
class B<br />
{<br />
public:<br />
virtual void fn() { cout << "in B" << endl ; }<br />
} ;<br />
<br />
class D : public B<br />
{<br />
public:<br />
virtual void fn() { cout << "in D" << endl ; }<br />
} ;<br />
<br />
B&<br />
foo( D& d )<br />
{<br />
return d ; <br />
}<br />
<br />
<br />
<br />
void<br />
main( int argc , char* argv[] )<br />
{<br />
try<br />
{<br />
throw foo( D() ) ; <br />
}<br />
catch( D& x )<br />
{<br />
cout << "Caught D: " << typeid(x).name() << endl ; <br />
x.fn() ; <br />
cout << "- b=" << dynamic_cast<B*>(&x) << endl ; <br />
cout << "- d=" << dynamic_cast<D*>(&x) << endl ; <br />
}<br />
catch( B& x )<br />
{<br />
cout << "Caught B: " << typeid(x).name() << endl ; <br />
x.fn() ; <br />
cout << "- b=" << dynamic_cast<B*>(&x) << endl ; <br />
cout << "- d=" << dynamic_cast<D*>(&x) << endl ; <br />
}<br />
}
And the output:
Caught B: class B<br />
in B<br />
- b=0012FF64<br />
- d=00000000
I would have expected that either 1) the D& catch handler would be invoked
since we are throwing an object of type D (even if we are using a B reference)
or 2) the B& catch handler would be invoked but the call to x.fn() would print
"in D"
My reasoning goes like this:
- I create a temporary object of type D and pass it into foo().
- foo() returns that same object via a B reference. But the *actual* type of the
object being returned is still D.
- While I could understand the compiler using the static type of the exception object
being thrown (in this case, B) to figure out which catch handler to use, since
the actual type of the exception object is D, surely D::fn() should be being called,
not B::fn().
GCC is doing the same thing so for once, it appears that MSVC is not in the wrong.
What's going on here and where's my misteak?

Well, first off you're not using pointers, you're using references. The virtual-ness of fn() is irrelevant because polymorphic calls only happen when dereferencing a pointer.
Second, foo() returns a B&. Since a B& object cannot be implicitly converted to a D& object, the D& catch is not invoked. That would be a downcast, which is not an implicit conversion. It doesn't matter what the "real" type of the object is. The return type of foo() is B&, end of story.

>>> Well, first off you're not using pointers, you're using references. The virtual-ness of fn() is irrelevant because polymorphic calls only happen when dereferencing a pointer.
Not true. Polymorphism still works even if you're using references. For example:
<br />
D d ; <br />
B& x = d ; <br />
x.fn() ; <br />
prints "in D" i.e. even though we are using a B reference, the program knows that we really have a D object and calls the appropriate virtual function.
>>> Second, foo() returns a B&. Since a B& object cannot be implicitly converted to a D& object, the D& catch is not invoked.
As I said, I could understand if this was the case i.e. the compiler uses the *static* type of the exception to determine which catch handler to invoke. What I don't get is why, given that the actual object being thrown is a D, the virtual function mechanism doesn't seem to be working properly. Or at least, as I would expect 
One of the guys at work here suggested that the object was being sliced, but since nothing is ever being *copied*, no slicing could possibly be taking place!
