Well, what bothers me is that there is no good tool for GUI at all. MFC is not productive enough (just see what you need to do to change a color of a button, for instance  ), and VB and .NET are slow and dependent on huge runtime.

I am writing an application for the PPC and I have a question regarding CView::OnInitialUpdate(). On my desktop version this method is called and I have put my initializations here for my pages on my tab that is displayed on the main view. It works just fine on the desktop. In the ppc version the OnInitialUpdate is never getting called. Does anyone have any ideas as to why? Is there a windows message I can generate to get it called? If so where?
Thanks for the help,
-Eric

Hi there,
I have installed the NT Option pack over NT 4.0 sp 5, and use the personal web server to run ISAPI extensions of my development. The problem is, once a web page accesses a certain extension (DLL) and it is loaded into memory, I can't seem to unload it (stopping the web service doesn't help). This of course prohibits changing the code and trying again, since I can't replace the DLL in my SCRIPTS folder, unless I reboot. 
Any Ideas?

Do you only stop the webservice?
I't might help if you also stop the iisadmin service...

Yep, you need to reboot.
In .NET though, this has been fixed from what I've heard.

You can change the ISAPI caching option to prevent ISAPI DLLs remaining in address space:
Open Internet Service Manager, and view the Default Web Site properties. Select the Documents tab and press the Configuration... button. On the App Mappings tab, deselect the Cache ISAPI applications checkbox.

when i was writing a filter a while back, after each build i'd rename the dll eg filter002.dll. Install that, and remove the config for the old ones in IIS. it still has a file lock on the old ones, but doesn't process them.
Then, every now and again you can reboot and clean up all the old versions.
Sorry to dissapoint you all with my lack of a witty or poignant signature.

Is there any way i can make a CDialog based dialog fade in/out??? (under win98).
Or maybe even keep them partially transparent?

There is no API functions for doing that on Win98, you need Win2k or WinXP for doing that.
I guess you could do it by manually, by taking a "screenshot" of the dialog, using bitblt(), and then draw it transparently with GDI+...
But then the the controls on the dialog would not work when you draw it transparent, because it's only an image of the dialog, not the real dialog...

It should be possible though with the standard GDI functions. Get a CRect of the dialog's size and position, then take a screenshot of that area as it stands (before displaying the dialog). Now load a bitmap of the dialog's initial state. Then, manipulate a bitmap structure in a loop to gradually fade the screengrab and bitmap together. Ok, it would be slow as hell, but it could work

i want to close my app while some of the threads are using socket connection. how can i stop these threads and clean
the memory used in the threads?
i had tried to add the codes following in the DestoryWindow() of the MainFrame:
while (m_MailThreadManager.GetThreadNum()>0)
{
CMailThread* pMailThread = m_MailThreadManager.RemoveHead();
pMailThread->PostThreadMessage(WM_MSG_ACTION_STOP_THREAD,0,0);
if (WaitForSingleObject(pMailThread->m_hThread, INFINITE) == WAIT_OBJECT_0)
{
CloseHandle(pMailThread->m_hThread);
}
else
{
TerminateThread(pMailThread->m_hThread, -1);
CloseHandle(pMailThread->m_hThread);
}
delete pMailThread;
}
but i found that the threads will cause windows exception
after the SOCKET connection even if ExitThread had been execcuted.
i don't know why since i had executed the ExitThread, the thread still exist and caused that SOCKET exception. and how
can i terminat them safely?
please help me!

You need to pass the Socket handle to the thread that you want to
use to terminate the thread that is waiting on it.
Use the "Thread Parameter" or other way.
When you close the socket from a different thread, the thread
that was waiting on "accept(...)" will return INVALID_SOCKET, so you will
know that if fail.
Hope this information helps

If I understand well, you want a thread to tell a second thread to stop waiting on a socket, and you don't know how to do that because the second thread is blocking on the socket call?
If this is your problem, make the second thread use select() [See MSDN for complete description] to see if the socket is ready.
If i am right, and want more information, just tell me

Yeah, you are absolutely right! what you say is what i really mean.
i have checked the MSDN about select(), which is used to determine
the status of one or more sockets.
now would you mind telling me:
1. what should i do to terminate a thread which has been blocked on a socket saftly.
2. what should i do to terminate a thread which has a socket (no blocking) saftly.
thanks a lot. hoping more help.

Uh hello, i have to program an application which uses an access database. I started in Visual C++ but suddenly i remembered Visual Studio also offered Foxpro. Allthough i have no idea what you can use Foxpro for exactly i know it has something to do with databases... Should i use Foxpro for my application instead?

Stick with Access.
I think they've abandoned Foxpro now

I personally like Foxpro, but i'm not huge into DB programming but haven't heard much of Foxpro lately, so you should probably take the advice of Nish.

FoxPro is very good for writing applications that interact with databases, that is it's primary function. The latest version 7, (just out recently) is pretty impressive with support for COM and Active X and XML. There is no .NET support yet but it is promised.

Hi, all you happy coders
I Hope somebody can help me with this problem I am having:
In my program i try to allocate about 500KB (in smaller pieces) with the new operator,
but it hangs in some function called '__sbh_alloc_block'...
Is this because I can't get more memory from windows...?
Thanks in advance,
Erik Hammar

From that sentence I assume you have a loop of some kind where you repeatedly call new till you get 500 KB is several smaller blocks [or so we assume]
Now are you sure your loop is looping the right number of times. perhaps it's a sort of endless loop!

No it's not a loop...
I create instances of about 5 classes, which each allocate one or two blocks of memory...
