The [findstring](http://www.gnu.org/software/make/manual/make.html#Text-Functions) function is what your heart desires:

&gt; ```
&gt; $(findstring find,in)
&gt; ```

&gt; Searches *in* for an occurrence of *find*. If it occurs, the value is *find*; otherwise, the value is empty. You can use this function in a conditional to test for the presence of a specific substring in a given string. Thus, the two examples,

&gt;     $(findstring a,a b c)
&gt;     $(findstring a,b c)
     
&gt; produce the values `&quot;a&quot;` and `&quot;&quot;` (the empty string), respectively. See [Testing Flags](http://www.gnu.org/software/make/manual/make.html#Testing-Flags), for a practical application of `findstring`.

Something like:

    ifneq (,$(findstring NT-5.1,$(VARIABLE)))
        # Found
    else
        # Not found
    endif

&gt; What is the comma here for `ifneq (,$(...`?

Parse it as `ifneq(A,B)` where *A* is the empty string and *B* is `$(findstring...)`. It looks odd because you don&#39;t quote strings in Makefiles.

    VARIABLE=NT-5.1_Can_be_any_string
    ifeq ($(findstring NT-5.1,$(VARIABLE)),NT-5.1)
        # Found
        RESULT=found
    else
        # Not found
        RESULT=notfound
    endif
    
    all:
        @echo &quot;RESULT=${RESULT} , output=$(findstring NT-5.1,$(VARIABLE))&quot;

It matches the given string and returns

There are two basic ways to subscribe to an event:

    SomeEvent += new EventHandler&lt;ArgType&gt; (MyHandlerMethod);
    SomeEvent += MyHandlerMethod;

What is the difference, and when should I chose one over the other?

Edit: If it is the same, then why does VS default to the long version, cluttering the code? That makes no sense at all to me.

&lt;!-- End of automatically inserted text --&gt;

So I am relatively new to Python and I am having trouble working with 2D Lists.

Here&#39;s my code:

    data = [[None]*5]*5
    data[0][0] = &#39;Cell A1&#39;
    print data

and here is the output (formatted for readability):

    [[&#39;Cell A1&#39;, None, None, None, None],
     [&#39;Cell A1&#39;, None, None, None, None],
     [&#39;Cell A1&#39;, None, None, None, None],
     [&#39;Cell A1&#39;, None, None, None, None],
     [&#39;Cell A1&#39;, None, None, None, None]]

Why does every row get assigned the value?

A variable returns `MINGW32_NT-5.1` or `CYGWIN_NT-5.1.` (yea, dot at the end)

Need to compare that given var contains `NT-5.1` positioned anywhere.

Using cygwin and would like to be compatible with pretty much any *nix.

Makefile : contains string

A variable returns <code>MINGW32_NT-5.1</code> or <code>CYGWIN_NT-5.1.</code> (yea, dot at the end)
Need to compare that given var contains <code>NT-5.1</code> positioned anywhere.
Using cygwin and would like to be compatible with pretty much any *nix.

Which would be better code:

or

    int index = fileName.LastIndexOf(&quot;.&quot;, StringComparison.OrdinalIgnoreCase);

How can I check if a string (`NSString`) contains another smaller string?

I was hoping for something like:

    NSString *string = @&quot;hello bla bla&quot;;
    NSLog(@&quot;%d&quot;,[string containsSubstring:@&quot;hello&quot;]);

But the closest I could find was:

    if ([string rangeOfString:@&quot;hello&quot;] == 0) {
        NSLog(@&quot;sub string doesnt exist&quot;);
    } 
    else {
        NSLog(@&quot;exists&quot;);
    }

Anyway, is that the best way to find if a string contains another string?




How do I check if a string contains another string in Objective-C?

What I am trying to do is read a .java file, and pick out all of the identifiers and store them in a list.  My problem is with the .split() method.  If you run this code the way it is, you will get ArrayOutOfBounds, but if you change the delimiter from &quot;.&quot; to anything else, the code works.  But I need to lines parsed by &quot;.&quot; so is there another way I could accomplish this?

I understand that CFLAGS (or CXXFLAGS for C++) are for the compiler, whereas CPPFLAGS is used by the preprocessor.

But I still don&#39;t understand the difference.

I need to specify an include path for a header file that is included with #include -- because #include is a preprocessor directive, is the preprocessor (CPPFLAGS) the only thing I care about?

Under what circumstances do I need to give the compiler an extra include path?

In general, if the preprocessor finds and includes needed header files, why does it ever need to be told about extra include directories?  What use is CFLAGS at all?  

(In my case, I actually found that **BOTH** of these allow me to compile my program, which adds to the confusion... I can use CFLAGS ***OR*** CPPFLAGS to accomplish my goal (in autoconf context at least).  What gives?)

Can I pass variables to a GNU Makefile as command line arguments? In other words, I want to pass some arguments which will eventually become variables in the Makefile.

Passing additional variables from command line to make

My project directory looks like this:

    /project
        Makefile
        main
        /src
            main.cpp
            foo.cpp
            foo.h
            bar.cpp
            bar.h
        /obj
            main.o
            foo.o
            bar.o

What I would like my makefile to do would be to compile all `.cpp` files in the `/src` folder to `.o` files in the `/obj` folder, then link all the `.o` files in `/obj` into the output binary in the top-level folder `/project`.

I have next to no experience with Makefiles, and am not really sure what to search for to accomplish this.

Also, is this a &quot;good&quot; way to do this, or is there a more standard approach to what I&#39;m trying to do?

I&#39;m learning JavaScript using W3C and I didn&#39;t find an answer to this question.

I&#39;m trying to make some manipulations on array elements which fulfill some condition.

Is there a way to do it other than running on the array elements in for loop?
Maybe something like (in other languages):

    foreach (object t in tArray)
       if (t follows some condition...) t++;

another thing, sometimes I want to use the element&#39;s value and sometimes I want to use it as a reference. what is the syntactical difference?

As well, I&#39;ll be happy for recommendations on more extensive sites to learn JavaScript from.
thanks
