Actually it's been quite a while since I had such problems. Mostly because I'm a) vigilant, and b) I use proven classes which handle all low level operations such as memory allocation and stuff.
Most of the troubles I've had recently have been reference counting on COM-interfaces. Actually, the last such a problem was not introduced by me, but by a colleague. I guess I'll fix that tomorrow, so that the damn out-of-proc server may terminate properly

No, not intentional. I just take some screen caps as the show plays, then I go back after the show's done and pick out the nicest-looking ones.

Ok... so I gotta get in on this. When, Where? So I don't have to be a beggar to your screencaps. ;P

It's not magic or anything. I use WMP 9 and turn off video acceleration (otherwise a screen cap wouldn't capture the video window). Then I set up Paint Shop Pro to do multiple screen captures with a hotkey (F11 or something like that). Then I watch the show

Pinky, are you pondering what I'm pondering?

You could use _stricmp() instead. That way you don't have to allocate a new string.
for(int i = 0; i < m_nCount; ++i) {
if(_stricmp(keyword, m_pStack[i]) == 0) {
ret = i;
break;
}
}

While applying SP5 to Visual Studio 6 I repeatedly received an error, to the effect of "C:\Windows\System32\MSVCP60.dll could not be opened" yet when the installation was complete it reported that SP5 had been successfully installed. Since this is the updated (for VS6) C++ Runtime Library, should I be concerned? Searching shows that there are 4 copies of this dll on the C: drive, all of the same version, but none exists in ...\System32\. Should I ignore it, or make a copy and drop it in the System32 folder? Or is this just an error on the part of the installer program, looking for a file on C: even though I specified a different installation location? The correct version does exist in ...\vc98\redist. Thoughts, anyone?

Sounds like some other application had the file locked. I'd be tempted to go ahead and try replacing it manually, probably with a reboot beforehand. Good luck.

Why can't I remove the window style WS_CLIPSIBLINGS? If I remove this style using ModifyStyle, it will be there again afterwards. Why?
|
|
|
|
|
According to the MSDN, WS_CLIPSIBLINGS can be specified when the window is created, but not modified.
Software Zen: delete this;
|
|
|
|
|
So, if I want to create a WS_CLIPSIBLINGS-less dialog, I must use CDialog::Create or something like that.
But Create is not called in the sourcecode generated by VC++, or is it?
|
|
|
|
|
You can specify WS_CLIPSIBLINGS in the resource for the dialog; it should be one of the options in the dialog's properties.
My point was that you can't turn WS_CLIPSIBLINGS on and off dynamically.
Software Zen: delete this;
|
|
|
|
|
The resource editor indicates that WS_CLIPSIBLINGS is NOT activated (Properties, Tab Styles, Check button "Clip Siblings" is not checked).
Then why does Spy++ (my code too) indicate that the dialog has WS_CLIPSIBLINGS?
The only way to set/reset that style is the resource editor, or I should create it using Create(...) with or without that style. Is that correct?

If I have an array of pointers to objects (class objects created using "new"), are the state of those objects preserved? IOW, if certain values existed in an object at the time it was placed in the array, will those values still exist when next the object is accessed from the array?
Several of those objects are created at various times and places in the program, and are subsequently accessed at various times and places as well.
Some of the items in the objects include STL container objects, pointers and other arrays with data in them.
In case someone might think that the array of objects to which I'm referring is an array of objects of the same type, that is not the case. I am referring to an array of pointers to objects (i.e. pointers to various objects of different types which inhabit the array). This, however, is besides the topic of my question which seeks to determine if object state persist.
Thanks for any insight in this matter.

So long as the array hasn't gone out of scope, then yes your objects have been preserved. If they have gone out of scope you have a memory leak, and the memory you are writing / reading to or from may or may not contain your objects - you should assume it doesn't! Sometimes running in debug mode can hide things like that.

Scope shouldn't be an issue, because the objects were created using "new", which means you are responsible for deleting them in the end.
Memory leaks are more what I fear.

Since the individual objects pointed to by the array elements are allocated from the heap, they persist until they are deleted. If the array destructor doesn't delete the objects pointed to by its entries, then the objects will survive the array's destruction. (Sounds dramatic, doesn't it  ).
Software Zen: delete this;

The question is not whether the objects themselves persist, it is whether the "state" of the objects persist.
I know it's my responsibility to call the destructor of each object in the end. So I know the objects are going to persist until I delete them individually. My real concerns are with the state of the objects with regards to the values they contain.
IOW, it is pointless to think every member variable of an object will be "const", or created on the heap, or of 'static' storage type. But when you're dealing with other aspects of C++ like STL, they have their own modus operandi.

Because you've created the objects on the heap, they will continue to exist and be valid until destructed, regardless of the disposition of the array containing pointers to them.

Hi, i'm trying to write a winsock layered service provider that filters some UDP traffic and logs it to a file with the ip. The problem is i don't know how to get the ip from in there. I wrote this code but it always gives me 0.0.0.0 as the ip address:
struct sockaddr_in sin;
int err;
int inlen = sizeof(struct sockaddr_in);
if(WSPGetSockName(s, (SOCKADDR *)&sin, &inlen, &err)!=0)
MessageBox(NULL,"Error","lsp",MB_ICONERROR);
char* address;
address = inet_ntoa(sin.sin_addr);
It does not give me an error, it just logs it as 0.0.0.0 
The definition of WSPRecvFrom is as follows:
INT
WSPAPI
WSPRecvFrom(
IN SOCKET s,
IN LPWSABUF lpBuffers,
IN DWORD dwBufferCount,
IN LPDWORD lpNumberOfBytesRecvd,
IN OUT LPDWORD lpFlags,
OUT struct sockaddr FAR * lpFrom,
IN LPINT lpFromlen,
IN LPWSAOVERLAPPED lpOverlapped,
IN LPWSAOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine,
IN LPWSATHREADID lpThreadId,
OUT INT FAR *lpErrno
)
Any ideas?
Thanks
