If I have this code:


void test(){
Map *m1 = new Map;
....
Map *m2 = new Map;

}

I am new to the .net programming. I am trying to create the .net project in my visual studio, but I can't seem to find it. Is it the CLR? If it is, why not just name it .net, instead to confuse...

I have updated my code.

Hi:

If I have code:


if(result != NULL && result.data != NULL){
...
}

If I have a class:


class test{

public:
test(){
...
}
};

This code is directly copied from msdn site, I did not write that

I read the documentation, the


map::end()

points to the past-the-end element, not the last element of the map.
The


map::begin()

I got some LNK4217 error message. I read a little documentation here: http://msdn.microsoft.com/en-us/library/aa3se25k%28VS.80%29.aspx
with example code:


// LNK4217.cpp
// compile with: /LD...

sorry, I am not allowed to do that. The function is written by another library. If I change the function, there are hundred of calls I need to update.

@laserlight
could you give me a code example?

Here is my code:


void func1(char * var1){
...
}

std::string str;

func1( str... /* question here */ );

yes, this is the question I want to ask actually.
if I change to:


std::string test(){
std::string var1;

var1 = "test";
return var1;
}

char * test(){
char var1[10];

var1 = "test";
return var1;
}


var1 is a local variable, so I was wondering if I return the pointer to var1. Could memory of var1 being freed when the...

so is there certain rule I should follow? I mean how do I know when I need static keyword, when I don't need? Can I ignore const keyword too?

also what does this method called? setter? what...

so even though we don't know where those strings are created, what's the reason not to change them? because some memory location could be read only?

I don't understand is that is npos returning a number?
What if I have several string here, does each string has its own npos? or npos only reflects the last call?

The documentation says if not found, npos is returned. How do I use that?


first = tempString.find_first_of(" ");
if(first == std::string::npos){
...
}


Is it something like this?

I read FAQ note from Gabriel Fleseriu here: http://www.codeguru.com/forum/showthread.php?t=231162

He explained this is a bad programming practice:


char* s = "Hello";
s[1] = 'a'; ...

Hi:

I have seen code like this:


class test{

const static string var1;

My code:


void func1() throw() {
...
}

void func2() throw(int) {
...
throw(1);

yes, but this works too:


testFunc( std::string( "cool" ) + "foo" );


The compiler knows to add a string with a pointer. How come?

Thanks, it works.

But why this one works:


testFunc( "cool" );

This one doesn't:

Thanks for your help.
But I tried, it doesn't work. It gives me 38 errors for that line.
I also tried:


testFunc( std::string a( "cool" ) + std::endl + std::string b( "foo" ) );

Also doesn't...

so how do I prevent it from calling the ABC destructor? I will need the ABC to be there for later usage.

This is part of my code:


void testFunc(std::string){
...
}

testFunc("cool" + std::endl + "foo");
