I've just bought 'COM+ Programming, A Practical Guide using Visual C++ and ATL'; I'm only a couple of chapters in but I'd recommened it.
It's on Hewlett-Packard Professional Books if you want to check it out

Thanks!

It's because there is something wrong with your code.

Probably the same cause.
(HINT: Try to be a bit more specific)

...if the code is wrong it should not run under win'98, right?

It just might. I used a ON_NOTIFY_EX macro where I should have used a ON_NOTIFY the other day. Worked like a charm on ME in both Debug and Release build. It also worked fine on w2k in Debug build, but created access violations in Release. So, there is one example. There are probably thousends of others.

Yes, you are right. But this one look strange to me. I don't know what to do.
Just now i tried to implement something from,
http://www.codeproject.com/w2k/access_api.asp
//////////////////////////
#define _WIN32_WINNT 0x0500 // allow Win2000 specific calls
#define VC_EXTRALEAN // Exclude rarely-used stuff from Windows headers
#include <afxwin.h> // MFC core and standard components
#undef _WIN32_WINNT // allow CFileDialog to build with
///////////////////////////
this stuff too not working...
anyway i try to fix the problem. thank you very much for responding.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

For my opinion it's compiled wrong ... you try compile for 32platform and unicode format; because i guess that your pc(with win2000) ... it's disabled a option for loading your bilt format(for win98).

Hi,
I would like to make an Active Document Server with Active Document Container capebilities.
In short I have tried to modifiy the Microsoft MFCBIND (http://msdn.microsoft.com/code/default.asp?URL=/code/sample.asp?url=/MSDN-FILES/026/001/803/msdncompositedoc.xml) sample to be a Server also. I want the MFCBIND to be running in a container (Word, Excel or myown) and still be able to use MFCBIND as a container for other Active Document Servers.
Have you tried something like that - nested Active Documents? I am really lost and I am about to think it is not possible..... but even the Visual Studio Wizard lets you define such projects but they dosen't seem to work correct....
Any help will be highly appreciated...
Best regards
Nyrup

A lot depends on how you are creating the temp file.
Have a look at DeleteFile on MSDN.

i would like to know if there is a predefined window class or control (or a free implementation) similar to iexplorer´s "mail" toolbar button, that is, it has a bitmap, an arrow on it´s right and it shows a context menu when clicked.
Thanks

I was try to incorporate this cool TabCrtl software
... http://www.codeproject.com/useritems/mditabs.asp
into my project.
I followed the instructions and try to
build my project and I get that C1010 error?
I didn't change any code but merely added
the .h and .cpp to my project.
What am I doing wrong?

You need to make sure that the cpp file has the "stdafx.h" file included in it. this is the precompiled header file.

1/ Open a CP account
2/ Post this question on the article in question.
Because you have opened an account, the author will get an email letting them know you asked the question.
BTW in this case, the problem is that the original article must have used automatic inclusion of precompiled headers, so go to the project settings and set them to automatically use stdafx as a precompiled header, instead of always doing so. Or #include "stdafx.h" at the top of the cpp file, but I presume he had a reason for not doing so in the first instance.

Hi.
Is it possible to enable/disable a message from the message for a time interval?
For example, let say I have a program that plays AVI files. For the first ten seconds, I want to disable the open button. I can disable a button. However, I found that if the user clicks on it while it is disabled, the framework keeps the message and class the message handler after I enable the button.
Is it possible to disable a button *completely*, or even better, ignore/unignore a specific message?
Thanks,
Kuphryn

m, the button is either disabled or not disabled. Possibly what is happening is the button is not even getting the mouse message until after it is re-enabled; ensure you are processing messages at an acceptable rate.

Well actually they are sort of interesting Nish, on Nudes

You could remove all the WM_LBUTTONDOWN messages from the message queue before reenabling the button.
Sorry to dissapoint you all with my lack of a witty or poignant signature.

I want to be able to automate my stock buying and selling, so I can go to work and not worry that I my stock will go down while I'm a way.
I want my computer to enter the stock symbol of my stock into for example msn, and then be able to parse the price from the site. It would then connect to my financial site and then be able to push the submit button to make the transaction.
What are the technologies that will enable me to do this? The sites are not XML enabled. Your help will greatly be appricated! What Functions do I need to call to do this? THanks in advance!!!

Is this a bug in MS's stl string code?
In this case _E would be sizeof(char). Why then would you make _MIN_SIZE 31 for a char but 7 for some data type that's larger than 31 bytes?
XSTRING line 519:
enum {_MIN_SIZE = sizeof (_E) <= 32 ? 31 : 7};

This is just an internal optimization trick. _MIN_SIZE is the minimum capacity a basic_string<E> can have. The purpose of this boundary is- to avoid memory fragmentation due to huge amounts of tiny blocks being reserved
- and to provide a reasonable starting size that a significant portion of strings will fit in without further reallocations.
So for small-sized types (like char), the minimum capacity is no less than 31 bytes, while for larger types we moderate our first reservation to 7*sizeof(E) bytes.

What's the best way to optimize this min size? Hack the code and redefine the min size?
I've been trying to use the swap trick to minimize memory usage but the little sucker wont budge beyond 31 bytes. I don't want to switch to vectors since I use a lot of the string functions.
I was trying to use stlport but the current version doens't like having VC6, .NET and the Platform SDK on the same computer. It refuses to compile.
