How can I check if a popup menu closed?
When I click with the right mouse button on my view I show a popup menu and mark something on the view (draw a rect where I clicked).
So, I want to know when the popup window is closed (switched off the screen) to redraw my view, so that my mark will be cleaned!
Is there any message the popup window send to the parent?

You could just send a message of your own before the window closes

I want my application to have maximized mdi childs and normal (or restored) mdi childs at the same time. Like seen in the Opera web browser.
Any ideas where I can start looking?
|

I can't comment on Opera, but with MDI this isn't possible. When one MDI Child is maximized they all are and vice-versa. My guess is that Opera isn't using MDI. You can check with Spy++ or Russ's WinSpector++ here on CP.

I have the following problem trying to pass a class as a parameter in a template function:
I am using a function like this:
pMainFrame->PlugNewModule(RobCtrlPage::IDD,RUNTIME_CLASS(RobCtrlPage));
the function looks like:
PlugNewModule(UINT nID, CRuntimeClass* pRTC)
{
UINT ID = nID;
CRuntimeClass* _pRTC = pRTC;
...
}
the question is, IDD belongs to RobCtrlPage, if we pass the class as a parameter we make the function easier. SOmething like:
template<typedef t=""> PlugNewModule()
{
UINT ID = T::IDD;
CRuntimeClass* _pRTC = RUNTIME_CLASS(T);
...
}
This way is easier because we just write
PlugNewModule<robctrlpage>();
instead of
PlugNewModule(RobCtrlPage::IDD,RUNTIME_CLASS(RobCtrlPage));
but i cannot compile  Why ????
I am using Visual Studio 6.0
Thanks !

Hi! Your post does not show <s and >s properly, next time you can check the "Display this message as-is (no HTML)" option (just above the edit area). Nevertheless, I've managed to read it through the source code of the page.
As for the problem, the correct syntax for calling the member function is
pMainFrame->template PlugNewModule<RobCtrlPage>(); Try it (if you please  ) and tell us if it worked. Even so, it's possible that you experience some problems (due to a bug in VC++) resulting in the function being called for a type different to what you specified! If so, please report it back, the thing could possibly be workarounded.

No, it doesn't.
I've got ...
warning C4042: 'identifier' : has bad storage class
error C2951: template declarations are only permitted at global or namespace scope

I would like some help. I need source code that will recursively search the registry and delete text found. It would need to work on 95/98/NT/XP/2000. Any ideas? Any help is appreciated.
Thank You,
Derek

I'm looking to return a list (perhaps in a list box) of all keys (ALL TEXT) that were found. If that Text appears anywhere in registry I want it added to my list. Then I can select/deselect what I wish and then delete the selected items. Allow someone to highlight and delete specific ones.

In my MFC application running on Win2k, the following code
fails in a worker thread, but succeeds in the main thread.
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
servaddr.sin_family = AF_INET;
servaddr.sin_port = htons(PORT);
servaddr.sin_addr.S_addr = IP;
int ret = connect(sockfd, (struct sockaddr *)
&servaddr, sizeof(servaddr));
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
In the worker thread, the error is always WSAETIMEDOUT,
never succeeds! But the same code in an applicaiton running
on WinCE works well! What's wrong with it?
Thanks a lot!

I believe you need to use a UI type thread instead of a worker thread because the worker thread doesn't have a message pump..

This is the array for the status bar:
static UINT nIndicators[] = { ID_SEPARATOR,
ID_INDICATOR_LINE,
ID_INDICATOR_CAPS,
ID_INDICATOR_NUM
};
==============================
and this is the function setting the indicators:
m_wndStatusBar.SetIndicators(nIndicators, 4);
==============================
Still, on the status bar, everything else shows up except "CAPS". Does anyone have any idea why?
Thanks! I appreciate it.

No need to reply to this concern. I've already found out the reason.

Sorry for the repost but after working with this almost all night I am still stuck --
I am having a problem using print and printpreview in a FormView.
If I build using MFC as a shared dll, all works as it should.
If I build using MFC as a static library, I get an error when the print function tries to create the dialog to show print status. Apparently when
Create(CPrintingDialog::IDD, pParent);
gets called in the CPrintingDialog contructor,
if (!_AfxCheckDialogTemplate(lpszTemplateName, FALSE))<br />
{<br />
ASSERT(FALSE);
PostNcDestroy();
return FALSE;<br />
}
in CDialog::Create fails because there isn't a valid document template name. Is this the document template name of my form view or one created by MFC for the print dialog? How do I make sure it gets set? I need to compile using MFC as a static library due to installation on other Windows versions.

Is it save to realloc a newed buffer, or do one have to use malloc?
<br />
LPBYTE pBuffer = new BYTE[1024];<br />
pBuffer = realloc(pBuffer,2048);<br />
delete[] pBuffer;<br />
<br />
|

I believe the result is undefined so you should try to avoid code like this. Might work until one day... probably the day when you are showing your project to a potential customer

It is undefined when you use realloc on a buffer that you allocated with new.
Probably the best way to do this type of operation is to use a vector instead:
<br />
std::vector<BYTE> myBuffer(1024);
myBuffer.resize(2048);
<br />
Best regards,
John

if you step into the new-handler, it actually calls malloc.
Do you consider that when stating that it's undefined?
Thank you for your answer.
The reason that I ask, is that I'm writing a specialized buffer, and thus cannot use std::vector.
I am using malloc, but just out of curiosity.

You can not mix and match new/delete with malloc/free/realloc. Just because version of the compiler implemented it using malloc means that the same will work for a different version.
The standard specifically states that delete can only be used with new.

Although the current compiler you are using calls malloc as part of its implementation of the new-handler, this is not specified by the C++ standard, and should not be relied on. Another compiler (or a more recent version of the compiler) can change the implementation so that malloc is not called. The result from calling realloc on a buffer allocated with new is undefined. While it may work with this version of the compiler when allocating a POD, it is not a good practice to rely upon an implementation detail that you have no control over. If you decide that realloc is the only way to go, don't use new for the original allocation - just use malloc.
You should be able to use a vector anywhere that you use a raw allocated buffer. What are you trying to do that you don't think will work with a vector?

Hi,
Looks like I'm having a brain fart this morning and can't remember how to cancel the closing of a property sheet.
I have two property pages, and I validate some settings in the CMyPropPage1::OnOk() handler. If the settings are invalid, I display a msgbox to the user and want to leave the property sheet displayed. However, it's closing after the user closes the msgbox! When the settings are invalid, I simply return from the handler (which appears to be wrong...). So, what do I have to do to keep it displayed??
Thanks!
Chris

Well when OnOK is called in the PropertySheet all the PropertyPageses that have been activated get their OnOK called. That means all the pages have been validated; therefor, no matter what the return is from OnOK on the Sheet it will close. Al least that is my experiance. It may be totally incorrect but it is what I tell myself to feel better.
So what do you do? In all my PropertySheets I validate at the Page level. That way if a page fails then I show message and return there.
Hope it helps.

I'm writing an application with heavy mt.
the app runs for about 20 seconds, and then crashes in a malloc call, either through new or CString operator <<
I HAVE used the mt runtime, and it doesn't help.
the linker complained about libc conflicts, so I exluded it with /NODEFAULTLIB
Is it dangerous to load an mfc dll, from an atl application?
Anyone with a hint?
|
|
|
|
|
No. But it is dangerous to have buggy code that trashes memory causing malloc to break.
You software is buggy. Look for buffer overruns or accessing memory that has been freed.
