Moving on ...

My experience with blogspot has not been pleasant so far. I have found the interface and the final page rendered broken many times. If I write just paragraphs of text, maybe that works fine. But in a technical blog where there is code and links and various other formats, blogspot fails miserably. I find the themes and other user interface oriented stuff within blogger crappy. Yes, you can edit the template but neither do I have the time nor interest in that.

Google should have improved blogger to really compete with other platforms - WordPress, Ghost etc. Blogspot, obviously, is not of high interest for Google.

Overall, I am not happy with the product. I will be (have already!) no more writing here on this blog. Will be continue to post at http://vivekragunathan.wordpress.com. See you there!

Passing CComPtr By Value !!!

This is about a killer bug identified by our chief software engineer in our software. What was devised for ease of use and write smart code ended up in this killer defect due to improper perception. Ok, let us go!CComPtr is a template class in ATL designed to wrap the discrete functionality of COM object management - AddRef and Release. Technically it is a smart pointer for a COM object.void SomeMethod() { CComPtr siPtr; HRESULT hr = siPtr.CoCreateInstance(CLSID_SomeComponent); siPtr->MethodOne(20, L"Hello"); }Without CComPtr, the code wouldn't be as elegant as above. The code would be spilled with AddRef and Release. Besides, writing code to Release after use under any circumstance is either hard or ugly. CComPtr automatically takes care of releasing in its destructor just like std::auto_ptr. As a C++ programmer, we must be able to appreciate the inevitability of the destructor and its immense use in writing smart code. However there is a difference between …

out, ref and InvokeMember !!!

When I was working on the .NET reflection extravaganza thing that I explained in my previous column, i learnt one another interesting thing, that is about the Type.InvokeMember. How will pass out or ref parameters for the method invoked using Type.InvokeMember ? If you are going to invoke a method with the prototypeint DoSomething(string someString, int someInt);then you would use InvokeMember like this:-object obj = someType.InvokeMember("DoSomething",
BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance,
null,
this,
new object[] {"Largest Integer", 1});or use some variables in the new object[] {...}. But what do you with the args if DoSomething takes out or ref parameters ?int DoSomething(out string someString, ref int someInt);Something like this will not work string someText = string.Empty;
int someInt = 0;
object obj = someType.InvokeMember("DoSomething",
BindingFlags.Public | BindingFlags.NonPublic …

Offering __FILE__ and __LINE__ for C# !!!

THIS POST USES SYNTAXHIGHLIGHTER AND HAS ISSUES RENDERING CODE ONLY IN CHROME
Not the same way but we could say better.
Visual Studio 2012, another power packed release of Visual Studio, among a lot of other powerful fancy language features, offers the ability to deduce the method caller details at compile time.
C++ offered the compiler defined macros __FILE__ and __LINE__ (and __DATE__ and __TIME__), which are primarily intended for diagnostic purposes in a program, whereby the caller information is captured and logged. For instance, using __LINE__ would be replaced with the exact line number in the file where this macro has been used. That sometimes beats the purpose and doesn't gives us what we actually expect. Let's see.

For instance, suppose you wish to write a verbose Log method with an idea to print rich diagnostic details, it would look something like this.
void LogException(const std::string& logText, const std::string& fileName, …
