My bet is that you need to do a rebuild-all. The line added just adds an extra 4 -bytes (a pointer) to the size of your object. If its declared before the m_Params member, then m_Params is now offset by an additional 4 bytes. If your .cpp file(s) have not been completely rebuilt since this declaration change, you may find that one file is using the old declaration and another the new one. This will cause assignnments etc to change the wrong members of m_Params.
To check this, move the declaration of m_pGFx... to after m_Params
Or just force a rebuild all

Hello-
I would like to use a very simple XML description to layout some customizable dialogs in an application. I was hoping I could find a relatively simple XML parser available as open source.
I looked at Xerces and although it would certainly do the job, it is far more complicated than necessary. Any suggestions?

or try searching for
CMarkup (Here on CP For Developers version, from FirstObject)
pugXML (Here on CP)
both are 'tiny' and do great job

for all c++ coders out there...
i need to write a program that determines dependencies between c++ source files. Besides parsing and scanning for "#includes" and "::'s" what else would do? I need to parse and find ALL calling dependencies (ie. function calls). How would yo go about it to try to encompass all of them (if possible)?
btw, I am most definitely not asking anyone to write code for me. I would like to hear your approaches and sugestions regarding such a problem. What patterns should I look for? Thank you.

Well, I've written a small part of what you are talking about here:
http://www.codeproject.com/useritems/includefinder.asp[^]
However, I've undertaken projects to do what you are talking about, and if I were you, I'd start with the source of a proven compiler like g++ to do this. If you are trying to do it from a "this would be cool to write" perspective, then start by getting yourself a good book on compiler architecture, like the Dragon Book (Compiler Principles, Techniques, and Tools[^]), or some such other book (there are probably other good books out there).
Good luck with it anyways

How to do that? I have a directory filled with *.gif images (but if it'd be more useful, I can convert them to *.bmp) and I want to have them displayed in a Picture box. How to do that?
I only have to know how to open an image file (*.gif or *.bmp or whatever) and display it in a picture box. I can manage all the other steps (Well, I guess I can...)
Tnx.

use the CBitmap class from the MFC to load *.bmp files. but then, you have to draw it with GDI
a Picture Box aequivalent is maybe the CPictureHolder class

"use the CBitmap class from the MFC to load *.bmp files"
But how exactly? I see no functions in that class or any parent classes that could do that...

Hi, I'm doing a simple packet filtering firewall as my final year project. I'm at the early stages of my project and I've already studied about the types of internet firewall out there and other security overview information.
So, I need detailed information on how to build a firewall. Can you guys point me to good tutorials/information that might help? I'm using Visual C++ to code and MFC to create the GUI. Also, since I'm doing it in a Windows platform, I've heard that I need some sort of a driver, can you help explain this part as well?
Thx,

For the winsock part of the design, I recommend this book.
Network Programming for Microsoft Windows, Second Edition by Anthony Jones and Jim Ohmund.

(this was a one minute search @ google )
another tip:
don't use the MFC Socket Class for Socket Programming, because under the hood, there are Win16 Functions(in version 4.x, i don't know, if this is in version 7 also so)

hmm..bout dat link to "Firewalls and Internet Security: Repelling the Wily Hacker" book.
i think i've read a similar book by Elizabeth D. Zwicky entitled "Building Internet Firewalls". do you think there's any difference between the two?
i've pretty much covered the necessary basics of firewall. so u know wat i should read for really complex stuff bout firewall?
thx,

Is there any way where one can migrate a process / thread from one computer to another connected computer and have the results returned to the first computer for load balancing?
Take for example I run two extreme memory-intensive program, minesweeper and solitair, and the program will migrate one of the processes to the other computer (which is running nothing) for better performance.
If this is not possible on pre-programmed applications like those stated above, then is there a way where new applications can be written such that this is possible?
thanks in advance

Therre are some tools that watch files and can get if the file change or not(I know how to do it),I want to know is that possible to get the changes for the file too? For example what is written to the file or the location of it or what is read from it?
I want to write a lock for my software and want to keep some information in a file,and now want to know if it is possible to spy it in this way?

Hi,
I made an atl server and added few interfaces, accidently my friend added an interface which is MTA, now i know MTA will fail in this design. Hence i want to convert it to STA. Is there any way to convert the existing interface from MTA to STA with minimum effort?
Thank you very much.

I assume you're talking about an implementation here, not interfaces. Interfaces are just a collection of methods.
In the inheritance list of the C++ class implementing the interface, change any occurence of CComMultiThreadModel to CComSingleThreadModel. In the RGS file, change the ThreadingModel value to Apartment.
