Visual C++ NOOB - Working with MFC DLL linking option in the project setting

Alright, must confess that I am indeed a NOOB when it comes to Visual C++ despite the fact that I learned C++ first and started to work with this language initially in my current work place (of 10 years++).

Had a chance again to work with C++ after so many years away from it, which I'm looking forward to because C++ is really the language that I'd really want to master.  So the current project is giving me quite a lot of headache considering it is an upgrade from the old Visual Studio 6.0 to the not-so-latest Visual Studio 2010, I would expect a lot of hurdles to overcome.  Thankfully my genius colleague who has previously worked on the upgrading provided me with his sample to look at, plus referring back to the old project in VS6, I finally able to get it up and running (without crashing, phew).

So here's what I've learned from this task.

1. Use of MFC setting
So the use of MFC setting has to be consistent throughout all projects within the solution.  If the main project is linked dynamically, then all dependent project has to be done so as well.  Otherwise there would be "unresolved external" issue throws at function that uses MFC classes or functions.

2. Wide Character
This is such a stranger to me last time, for I didn't know much about the differences in wide character and normal ANSI character.  After doing other projects, I've finally able to understand what are they.  Yet, in VS2010, the setting of the project: UNICODE, MULTIBYTE, or the standard ASCII would result in different handling of the wide character string.  So, this is something that I need to be careful about and to take note in future development.  Well, considering the trend now is multilingual, better start cracking to learn it.

3. External Dependencies
Again another thing that's so foreign to me last time, and again it is something after doing other project in other languages that I've finally able to at least grab hold of the concept.  In VS2010 for C++, there are a bunch of settings for external dependencies: include, lib, src, reference (all under the VC++ Directories setting), and then Additional Dependancies under Linker -> Input settings.  These are all so easily done in order language, but in C++, man that's...  Harder...

Alright, that's all to remember for now...

Yahoo! Messenger voice call & video call disabled, why?

Was trying to help my colleague to troubleshoot her laptop, where the Yahoo! Messenger voice chat & video chat are disabled even though the setup of the sound & video are all correctly configured.  Yet, it will still throw the error message "Your computer is not connected to the network", which is quite amazingly considered that the wireless network is working plus the Skype is able to make the call. After several finding on the Internet and on some help site, non of the solutions are able to solve the problem.  Then I recalled the other colleague is also using the same laptop and her Yahoo! Messenger is able to use video call & voice call.  I was guessing the whole time of what could be the possible cause that hers is working but not this one.  Then a thought came to my mind, could it be the firewall? The firewall is correctly configured, so what else inside there that is blocking the connection?  The other security software that's installed is the Trend

Sport's Injuries - Treatment for bruises

I have a knock on both my legs last Sunday during a Futsal session. I have a knock on my lower right shin, while sprain my left ankle. It is not a pleasant experience at all to have both legs injured. It is very painful and totally immobilized me. What's important right now is to get it treated. I have tried to elevate both my legs in order to not let the blood concentrated at the injured spot, plus put ice at the injured area. I have even consulted with a doctor regarding the injuries, and am thankful that there's nothing wrong with my right shin. Still, it's not healing that well because the swelling has not resided. Since I'm living alone, it will be hard for it to heal because I need to be mobilize all the time. With the help of the Internet, I'm trying to surf for information that could help to provide first-aid treatment. The following are my finding from the Internet and from family tradition treatment: Elevate the injured leg. Apply ice for about 30

Web Development: Disable, Validate, & Enable Buttons

I bounced into this problem during a Web UI development, of which I'd say it's quite a common issue. Whenever a button is clicked, ideally it would be good to disable it to avoid continuous clicking. Of course, it may not be the case in certain circumstances, i.e. loading of images, of which sometimes clicking the button again would surely making it load faster. However, in the latest development that I involved in, I need to make sure that the button as to be disabled to avoid continuous clicking that would cause some Javascript error that would cause the whole website to stop working. I've no idea why this is happening, and my only explanation should be because the execution time is short & it's AJAX, therefore the continuous clicking would cause some process not able to be executed timely and causing this issue. So after some research on the Internet, I found that in order to disable the button during a button click event that has a postback, the onclick event
