Properties C# 2.0 - Not Elegant Enough !!!

Prior to .NET 2.0, there wasn't the facility in C# to opt the visibility level for the get and set property or indexers. And i take my comment in my previous post that C# does not provide the facility of having different visibility levels for the get and set accessors. While that is partly correct, it is no more in C# 2.0.

And obviously it isn't in the easy and elegant way. Take a look at this code snippet:-

public bool LogToStdError
{
get
{
return _log2StdError;
}
protected set
{
_log2StdError = value;
}
}
I do not have to explain the code except there are some restrictions while having different visibility levels for the get/set accessors of a property.

1. You can provide an explicit visibility either for get or set. Hence the following code will throw an error:-

public bool LogToStdError
{
protected get
{
return _log2StdError;
}
protected set
{
_log2StdError = value;
}
}

2. The visibility thus explicitly specified must be a subset [restrictive than] of the property declaration.
For example, if the property declaration is protected, then the get/set accessor cannot be like say public. So the following code throws an error:-


protected bool LogToStdError
{
get
{
return _log2StdError;
}
public set
{
_log2StdError = value;
}
}

I feel that these restrictions are stupid, and this resulted because of the syntax. I just thought of some ideas for a bit elegant syntax for the property definition.

1. The get and set accessors individually have to specify the visibility level.

bool LogToStdError
{
public get
{
return _log2StdError;
}
property set
{
_log2StdError = value;
}
}

2. The property declaration syntax must not bear any visibility level unless the associated get/set accessors do not bear any. For example, in the property definition below, the get/set accessors are public:-

public bool LogToStdError
{
get
{
return _log2StdError;
}
set
{
_log2StdError = value;
}
}

and as per this property definition, the get/set accessors are protected:-

protected bool LogToStdError
{
get
{
return _log2StdError;
}
set
{
_log2StdError = value;
}
}

3. If there are visibility levels specified neither in the property definition nor in the accessors, then the default visibility level as specified for C# [I guess internal] will be applied for the property accessors. Hence the get/set accessors are internal for the following property:-

bool LogToStdError
{
get
{
return _log2StdError;
}
set
{
_log2StdError = value;
}
}

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 …

jqGrid: Handling array data !!!

This post is primarily a personal reference. I also consider this a tribute to Oleg, who was fundamental in improving my understanding of the jqGrid internals - the way it handles source data types, which if I may say led him in discovering a bug in jqGrid.

If you are working with local array data as the source for jqGrid, meaning you will get the data from the server but want the jqGrid not to talk to the server anymore, and want to have custom handling of the edit functionality/form and delete functionality, it is not going to be straightforward - you need to have a decent understanding of how jqGrid works, and you should be aware of the bug Oleg pointed in our discussion. I repeat this is all about using jqGrid to manage array data locally, no posting to server when you edit or delete, which is where the bug is.

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, …
