You should not execute any code of yours if the nCode parameter passed to your hook procedure is less than zero (actually it should be equal to HC_ACTION, which is defined as zero in WinUser.h).

int main(int argc, char** argv) is better than int main(), because with the former one, your program can analyse the command line parameters passed to it. The number of argument passed is available in the argc parameter, and the arguments themselves can be accessed by the accessing the argv parameter. …

If you're using MFC, then the window handle is already stored in a data member of the CWnd class known as m_hWnd. So, m_hWnd is all you need: [url]http://msdn.microsoft.com/en-us/library/zwdbkfhc%28VS.80%29.aspx[/url]

What array in MFC? MFC has many array types (string array, word array, etc.,). See the MFC collections here: [URL="http://msdn.microsoft.com/en-us/library/942860sh%28v=VS.80%29.aspx"]http://msdn.microsoft.com/en-us/library/942860sh%28v=VS.80%29.aspx[/URL]

If your code doesn't work within the IDE, there's no question of shipping it ever. The debugger does you a huge favour by watching what you're doing with the memory and tells you when your code does something insane (like stomping on memory that it doesn't own). Single stepping should …

I don't see what can you save by squeezing out anything from that tiny bit of code shown. Take a look at this: [URL="http://www.flounder.com/optimization.htm"]Optimization: your worst enemy[/URL], which might clear up a few things for you.

The name of an already running process cannot be changed dynamically. You cannot "hide" your process from the list of processes shown in task manager. Something highly esoteric like kernel patching can be done, but if you didn't know even that much, chances are that you aren't going to do …

If you were hosting the website on a Windows server, you could have the core of your application written with c++ as an ISAPI DLL, and it could be loaded by IIS. Please search google for ISAPI filter.

Just include the precompiled header (stdafx.h) in all the source files before including any other headers. The precompiled header option can come very handy if you've a boatload of headers that you aren't going to change, so that it won't need to be built with every compilation!

Use the _T macro, which will automatically convert literal strings to the appropriate type (Unicode or MBCS), based on the build type. In short, a good thing to do: Always enclose literal strings in the program within the _T macro. For example: [CODE]SomeAPICall(_T("Some literal string"));[/CODE] See [URL="http://msdn.microsoft.com/en-us/library/dybsewaf(VS.80).aspx"]Unicode Programming Summary[/URL].

Cast the void pointer to the appropriate type and use it. See [URL="http://www.cplusplus.com/doc/tutorial/typecasting/"]Type Casting[/URL].

There's no one such best c++ compiler. "Best" depends on what you're looking for in the compiler. I do a whole lot of c++ programming on Windows, and for me, the Visual C++ compiler is the best.

You could use one of those open source compression libraries. Last time I needed compression, I used the [URL="http://www.7-zip.org/sdk.html"]LZMA SDK[/URL].
