Which makes little sense since the HIWORD() macro already casts its result to a WORD . The int that the compiler is complaining about is on the left of the += operator, not the right.

I don't understand why, since the expression on the left IS a WORD. And we have no knowledge of this HIWORD macro; it maybe does not cast to a WORD.

I have reduced warning level to 3, and this warning does not appear.
Thanks for help!

Which does nothing but mask this and other potential problems. Leave the compiler warning level at 4 and fix the problem correctly. The compiler generates warnings/errors for a reason. If something wasn't suspect, there'd be no reason to warn you.

How refreshing! It's not just me that works that way, then

Hi, newbie here,
I was wondering what's the best way to use the CMemoryState object to check for memory leaks in a MFC program.
I want to set a checkpoint at the very beginning of the program and the very end, so in what functions should I call
oldState.Checkpoint() and newState.Checkpoint()?
|
|
|
|
|
Call the CheckPoint() method of a CMemoryState object where you want to start tracking. At the point where you want to stop tracking, call the CheckPoint() method of a second CMemoryState object. Then, call the Difference() method of a third CMemoryState object, passing to it the other two CMemoryState objects.

I know how to use the functions, I want to know where is the best place to call them in the App.
I was calling the oldState.Checkpoint() in the App() and
newState.Checkpoint() in App::ExitInstance() but it returned a difference.
When I called oldState.Checkpoint() it listed (I think) a CDocTemplateManager object and a CSingleDoctemplate object.......
So this is obviously not the best place to call oldState.DumpAllObjectsSince() to check overall memory usage.
Is there a function after App::ExitInstance to do the difference check in?
|

Generally speaking, in a DEBUG build you'll get this behaviour anyway providing your CPP files have the '#define new ....' stuff in them.
Are you calling CheckPoint before or after calling the base ExitInstance()?

I don't know what you mean by '#define new..."
I'm overriding the MFCApp::ExitInstance() function and calling the base ExitInstance(). Then I do the object dump, so I can't see why a few objects are still allocated.
BTW I am extremely paranoid about memory leaks after having lots of trouble with my last PC (crashing.......sloooowdown etc..)

I need to link to this lib ws2_32.lib, and would like to know how to do this in the project->settings->link tab.
What exactly do I type in, and where in the project->options text box in the link tab?
Thanks,

Enter ws2_32.lib in the Object/library modules box.

#pragma comment(lib, "ws2_32.lib") also does the trick

Hi
I am creating a project (base in a single document), I modified the initial class *View(at the end of the wizard) to be based in CFormView, so that the project is like one based on dialogs (but with other classes and format).
I set up a tabcontrol in the window, and I want to get the other frames because nothing appears in the tab.
I made some other examples but as this one is based on other classes, I have no idea how to get the information.
Can anybody help?
Thanks

I see that given an ftp site, you can use CInternetSession, CFTPConnection with
char* ftpserver = "ftp.microsoft.com" for e.g.
So if I have instead an IP adress for a computer, how do I get the CString for the fptserver.
Basically I need to download some data files off a given IP adress programmatically. Any suggestions appreciated.
Thanks,
ns

hello everybody,
I want create a listbox dynamically on the click of a button in a dialog box.
i had used the following code then also it is not visible when ever i click a button
CListBox clb;
clb.Create(LBS_SORT,CRect(10,10,100,150),this,123);
this->Invalidate(TRUE);
even i had commented the last line then also it was not visible.
thank you.

You need more styles than just LBS_SORT, like, for instance WS_CHILD and WS_VISIBLE, although the latter can be done by clb.ShowWindow(SW_SHOWNA).

You need more styles than just LBS_SORT . Add to that:
WS_CHILDWINDOW<br />
WS_VISIBLE
While not required, you might also need:
WS_TABSTOP<br />
LBS_NOTIFY<br />
LBS_SORT<br />
LBS_NOINTEGRALHEIGHT

I presume the problem is not with window styles. You are creating the CListBox control object within the local scope. The object will get deleted once the program control exits the function. So try something like this:
CListBox m_pclb; //In header ( .h file )
In .CPP
m_pclb->Create(WS_VISIBLE | LBS_SORT,CRect(10,10,100,150),this,123);
this->Invalidate(TRUE);
This should work!!!
