OK, What's going on here.
I have a C++/MFC application, and happily starts consuming memory slowly. Then when I hit the minimize box on the application, *poof*, all the memory that the application is consuming goes way down. Bring it back up, and it starts munching again slowly, minimize it, and the memory utilization goes down!
What's going on when I minimize an application?

That appears to be standard behaviour. I just tried it with Windows Task Manager where I watched the memory usage of various apps. Every one of them reduced the memory usage when they were minimized. I do not know what happens to the memory, maybe windows automatically writes it to the swap file, or Task Manager looses track of it?
Whatever it is, I wouldn't worry about it unless your app is somehow loosing data.

Ah, I'm too sleepy to be working today. Yes, it goes down, but the total commit stays the same. *Whew*

It's by design. Windows is trimming the working set of the application. See KB article 293215[^] for an explanantion (and some code to prevent it, should that be necessary).

Hello
I have a char * m_Str which is equal to "Test A"
I have another char* Str which is equal to " of"
I want m_Str to be equal to "Test of A"
So I need to put " of" into m_Str beginning in position 4
so my function could look like this:
bool Insert(char * Str, int Index)
where index = 4 and Str = " of"
thanks,
Lino

you should pass a parameter to the function to know the maximum number of characters the destination buffer can contain.
I submit another way, with CString, but you will be able (i hope) to adapt it to you problem.
<font color=#0000FF>void</font> myClass::Insert (CString Str, <font color=#0000FF>int</font> Index) {
CString strTmp = m_Str.Left(Index);
strTmp += Str;
strTmp += m_Str.Mid(Index);
m_str = strTmp;
}

it's a char* not a string...and I have to leave it a char* so I don't think you're solution will work.

|
|
you have to reconstruct a new char* string.

useloops to find the position where you want to "insert" the new string...
after that, use malloc, strcpy, strcat, ...

instead of asking me to adapt your solution to my problem just provide what I and other on the board are looking for if not then do not reply...keep your opinion to yourself.
don't reply to look like a hot shot...
get a life and in the future do not reply to any of my posts...your responses are not welcome nor needed.

no you were not helping...and wake up this is a message board you should only be responding if you genuinely want to help. NO ONE IS FORCING YOU SO IF YOU DON'T HAVE PATIENCE AND ARE FRUSTRATED AT WHAT MAY SEEM TO YOU AS ROUTINE CODING THEN YOU SHOULD OPT OUT OF RESPONDING.
This has nothing to do with homework IT IS A MESSAGE BOARD WHERE YOU COME TO GET HELP FOR ALL!!! (Homework, leisure, work...whatever it may be)
so shut it!

you cannot directly insert chars ( or sub string ) in an existing string, you need to rebuild the a string with the diffeernt parts.

One way would be:
char *m_Str = "Test A";
char *Str = " of";
char szResult[10] = {0};
strncpy(szResult, m_Str, 4);
strcat(szResult, Str);
strcat(szResult, &m_Str[4]);

Hi,
Does anyone know how to hide a window's title bar on a Win32 app?
Thanks in advance!

Use SetWindowLong API call and pass in a modified windows style. Look up the various WS_XXX window styles in MSDN. I *think* (off the top of my head) that you want to remove the WS_CAPTION style. But you may also have to remove others.
Once you have modified the style you need to call SetWindowPos like so:
::SetWindowPos( hwnd_, NULL, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED | SWP_NOACTIVATE );
SWP_FRAMECHANGED is the critical part that causes Win32 to refresh the window properly.
You can use GetWindowLong(GWL_STYLE) to get the orginal window style and then modify that accordingly.

Hi,
Thanks for the help but I cant make it work. I can remove other WS_*** styles but not WS_CAPTION. For some reason my window has a caption bar by default. Do you know any possible reasons why?
Thanks again!

You might have to remove other window styles that would also cause Windows to draw a caption bar. The ones that come to mind are WS_MAXIMIZEBOX, WS_MINIMIZEBOX, WS_OVERLAPPEDWINDOW and WS_SYSMENU, but there may be others as well.
