The pointer arriving in the thread function is correct. But the structure it points to has a pointer member (probably a CDialog *) which is not allocated on the heap! That one is the pain, and it doesn't appear in his posting.

Each thread has its own message map. As a result, you can't pass MFC objects that refer to windows between threads. The best you can do is pass the window handle between threads.

hello @all,
i have a mdi program. in the mainframe you have for example:
File -> Close
i would like to hide 'Close' to the users until the correct password entered.
enter password:
View -> Password
the 'Close' should not be gray or something like that. the user should not see that there is something like the 'Close', until he enter the right password.
i hope you can help me.
thank you very much

Off the top of my head, you could have a ON_COMMAND_UPDATE for the mdi child (which is where the
close command ends up) and use pCmdUI->SetText (m_bCanClose ? "Close" : "Password") to change the
text. You would also need a command handler to change the behaviour between password entry and the
normal closing.
For a "proper" app, you should load the menu strings from a resource rather than hardwired as above,
but you get the idea?
Iain.

I'd like to insert a checkbox in the dialog created by SHBrowseForFolder. Any hint, please ?
Thanks in advance

Straight from MSDN:
If you implement a callback function, you will receive a handle to the dialog box. One use of this window handle is to modify the layout or contents of the dialog box. Because it is not resizable, modifying the old-style dialog box is relatively straightforward. Modifying the new-style dialog box is much more difficult, and not recommended. Not only does it have a different size and layout than the old style, but its dimensions and the positions of its controls change every time it is resized by the user.

Hi !
Somebody knows about a software (or an option in VC++) which would only display the code contained in precompiler instructions ?
I mean:
#ifdef hello
int i=9;
#else
int j=10;
#endif
would only be displayed as
int i=9; if hello is defined. Otherwise, it would dispaly
int j=9; of course.
Reason is, in my new job, i have to do with realtime applications, and the code is full of precompiler instructions, so it is quite unreadable  .
Thankxx

See /E, /P and /EP compiler switches. This is not exactly what you need, but can help. You can also use Go to Definition function to see what precompiler value is defined.

When running a debug build using "Go"(F5), the debug output window shows memory leaks after the termination of the app.
Commercial products are considerably more sophisticated, but tend to be expensive and complicated.
|
|
|
|

In debug mode you can see the memory leaks only if you have created your application using the wizard and MFC.
Not everybody uses MFC and/or the built-in wizards.
What you have to do is either something like:
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
Which is done automatically in MFC and WIZARDS.
Or you could overide the new/delete (and their array versions) and provide your own memory leak checks.

But everybody who has to ask such a basic question definitly should.
Please get me right:
I am not attacking the question on memory leak detection, but the implication in the answer that beginners should not be using the Wizard. We can discuss about MFC, but the Wizard is definitely a good thing to get your Project going: Setting up the whole mess is very error prone.

We had a long discussion about that on the forum in June 2002, and it came out that one of the best software with a free demoversion was Glowcode. You may take a look at it.

Use something like Boundschecker.
Or write a wrapper that reference counts memory allocation and memory freeing.

I want to write a Internet Logger that logs all visited websites during a dail up session. I have 2 questions:
1. How do i know the URLs of the websites being visited
2. How do I hide my program from the ctrl+alt+del list?
(I am allowed to show an icon in the system tray, but i have to prevent the user from terminationg the app- I already know how to prevent the user from exiting the application in the normal way- but what if he/she uses ctrl+alt+del?)
Thank u.
Satya Kiran.

You could always takes screenshots at regular intervals, pass them back to your spy server, and then use ocr to capture the urls lol
