Hi all,
Im kinda new to MFC programming, and I was wondering if anyone knew of a place where I can find some source code or at least a tutorial to show me how to implement one into my Dialog based prog.
Ive made one for a Windowed view program, but am having trouble with the dialog version one heh!!
If you can help, id appreciate it!!
Thanks
Ashman

Merry Christmas to all members from Simi, I m lkn for a script which can help me to retrieve directory information and root folder of a ip address or a url. i made in vb but it only searches my local drive of computer but not on the net. plz let me know if you have any part of the code and then i can try to develop more . i think i read it somwhere most of the developers have used c++ for this script but i not sure. i guess this is the code which most of the robot spiders are using. i came across asptear but they don't provde source for their .dll, it doesnt work properly. if you come across any articles pleez let me know.
Merry Christams

Good Afternoon,
I've been writing code for about two years, C++, VB, Java in a box ( no coder guru over the shoulder stuff ). Am self taught, through books, and powerful( kiss up, kiss up )websites like this one. But I am sensing something is missing. All the examples/books/source code is kinda written in isolation to prove a single point, and not "this is how to write good software". I realize it is improbable to expect a standard way of writing code that is consistently expected... ASSERTs always go here... or are there things that most good coders do consistently? Sounds like I'm confused, doesn't it?
Here is my point( finally )...
would it be possible to have a complete sound commercial application written by a respected coder posted, chopped up by other good coders, and realize some sort of Best practices with reasons. Ie. I've read Newcomer's stuff about having if( DebugLevel ) do these things, then a novice could change the application debug level, and inform him of specific wrongs, but I've read other docs that say use lots and lots of ASSERTs and when problems... debug.
I realize this is an overwhelming task, but if done, would speed the process of novice coders, like me, becoming efficient with good practices as a foundation. Not to mention how it could affect the industry...
Maybe there is something out there like this already. If so, I'd love to see it an participate with questions and an open mind.
Thanks!
Scott!

Hi,
There are some good books on this topic: Writing solid code, Code complete, etc. They are trying to cover a topic of how to write a good software. I strongly recommend to start with them (check also Extreme Programming), although I agree that there is a space for a good book, covering maybe one big project and revealing some code techniques. But there will be always a place for small articles, covering in more details, how to do this or that, e.g. how to implement trace, logging, assert, etc.

There's no one best way, you can start an argument about any coding technique you could name.
Still, I think that "Code Complete" by Steve McConnell (Microsoft Press) is about the best book on the overall process of actually writing computer code. If you haven't read his book, I strongly suggest you do so. This book is written by a person who's written a lot of commercial code. He's not a pointy headed academic spouting theory, he's speaking from real experience.

Writing good code is more art than science in many ways.
There are no silver bullets. Everyone's style is different, and everyone works best in different ways. The trick to writing good code is to be consistent in whatever methods you choose, and always follow them.
Having said that, I'll third the recomendations for the MS Press books "Code Complete" and "Writing Solid Code", however I should also point out that these books are getting rather long on the tooth and are showing their age. Don't take them as gospel, but rather as advice. If the advice works for you, use it. If it doesn't, don't.
Also, these books are big on a few techniques which many find of questionable use. Hungarian notation is almost universally hated by people with lots of experience (although a few things such as m_ seem to still be popular, even among people that normally hate hungarian notation). Also, at least one of those books recommends placing constants first in equality tests (ie: if (10 == variable) since this will generate an error if you only use one = instead of 2. I don't agree with this practice, since it makes the logic much harder to read. Instead, I recommend devloping a near manic compulsive double-checking of your code everytime you type the = character. It's more error prone in development, but it doesn't screw up everyone that has to read your code for the rest of it's life.
Another book i'd recommend is "The Pragmatic Programmer" by Andrew Hunt and David Thomas (Addison-Wesley press). This book is a little more about process and management, but it includes some good gems of programming advice.

> Hungarian notation is almost universally hated by people with lots of experience
Make sure we do not confuse *experience* with *age*. Lots of the "older" crowd that I know, that were coding before the advent of (reverse) hungarian notation, or other common naming conventions, tend to not like it. The same goes for most of the Unix-heads that I know and have worked with. The ones that were "raised" on it, however, tend to like it.
Personally, I can speak from (bad) experience that nothing is worse than having to go through someone else's code who thinks that all variables should start with an "_", and then just have no naming convention whatsoever. Can you tell me anything about the following variables (besides their names)?
_Id
_RetValue
_StatusValue
_BookObject
What types are they? Pointers? Objects? Basic Types? Member Variables?
How about these?
m_iId
_dwRetValue
m_bStatusValue
_pBookObject
Even without knowing exactly what convention is in use, you know more about these identifiers than you did with the ones above. When dealing with smaller projects, it is not such a big deal. When dealing with megabytes of production-server-quality code, that little bit of knowledge can save LOTS of time (and money).
But I agree with the fact that using a naming convention does not make one a great coder. There are still people out there that may know all of the naming conventions, use them all the time, but still do stupid stuff like writing functions that take complex, or memory-intensive objects by value instead of by reference, or taking a _bstr_t as a parameter when a BSTR would do fine (and not require the allocation and deallocation of memory).
You have to learn the right thing to do, and then do it. Practice does not make perfect. Practice makes habit (age reference). *Perfect* practice makes perfect.
Good coders are concerned about both stability/robustness and speed. Good code is fast. Good code is robust. A few things (most) good coders do (by no means a complete list):
o Comment their code *well*
o *Always* initialize
o *Always* check any pointers before use
o *Always* check any return codes/values
o Never confuse NULL with NUL
o Know when to use a temporary (and when NOT to)
o Never use "catch( ... ) { /* Do Nothing */ }"
o Know how to read a crash-dump (or at least how to read the registers to know if you dereferenced a NULL, or had garbage data, etc.)
o If accepting a pointer to a buffer, accept the length of that buffer, too
o Do not use ::printf(...) when ::puts(...) will do (and similar)
o Do not take wrapper objects (or string objects) as parameters when the actual type (or a char/TCHAR pointer) will do (e.g., do not accept a _bstr_t when a BSTR will work)
o Do not use a dynamically-allocated string class when a stack-allocated buffer will do
o Always use the "length-specified" versions of string manipulation functions (like ::snprintf, ::strncat, etc.)
o Be aware of platform-specific (like the processor you are targeting) concerns/optimizations, alignment issues, etc., and code accordingly
o Know the "cost" of anything that you use (like STL container classes, COM, DCOM, etc.) and know how they do and do not work
o Use dynamic memory allocation only when necessary (esp. when doing multithreaded development and targeting a multiple-CPU system)
That is a good start...

Does anyone knows of a window DLL which can help to detect wm_message of an active window? I need this dll urgently.

Alright I was going to try and solve this problem on my own, but with school I just don't have the time and its really starting to bug me. Here it is. I want to have a menu item that when selected will change the dimensions of the main dialog. I'd like it to be able to resize the dialog to fit the screen. I'd also like to have a 640x480, 800x600, and a 1024x768 item that when selected will change the dialog to these sizes. I've tried using MoveWindow(), but this only seems to work in the dialogs initialization. I'd like to solve this myself, but it's gotten to the point that not having the answer is too annoying. Thank you.

Use SetWindowPos() to set the position and size of the dialog at the same time:
SetWindowPos ( hwndDialog, NULL, 0, 0, nWidth, nHeight, SWP_NOZORDER );

How would I go about building a custom font application?
E.g. In an Indian language.

How can I implement an application with the web view of a file like in Windows Explorer? Any ideas?

The Win32 console API has a lot of functions to change
a console window's size, color, scroll range and whatsoever.
It is even possible to change the window's code page.
(Normally, it is 437 on US english systems and 850 on german systems).
The font normally used by console windows is not capable of displaying any other codepage than the system's default code page; if for instance I try to display text using the ANSI codepage (1252), some characters are not displayed properly.
If I change the console window's font to a non-bitmap font (such as "Lucida Console" or "Andale Mono"), text can be displayed in any codepage whatsoever.
However, the only way to change the console window's font seems to be using the console window's property menu or the control panel applet 'Console'.
I would like to change the font *programmatically*, that is, without user intervention.
Any clues?
