Change the style:
m_List.ModifyStyle(0,LVS_REPORT);
Insert a few columns:
m_List.InsertColumn(0,"abcd");<br />
m_List.InsertColumn(1,"efgh");
this is this.

I need to display some visualizations base on output sound from speaker.
How could I do that? (No DirectX)
|
|
|
|
|
Get a flipchart and a pen. Open the flipchart and pump up the sound. Then, each time you hear a drum, move your pen up and down, while, during the song, slowly moving your pen from one side of the chart to the next.
If you do not want to use DirectX, try using an A/D-converter to feed your data back to the PC (USB or Legacy Ports).
Cheers,
Sebastian

If I was you, I would try, lets say, the Audacity source. Audacity is an open-source sound/wave editor/filterset, which might save you a lot of work.
They should do something like that somewhere.
If I was to record my own sound on the computer, I would retrieve the input from "Stereo Mixer" (which should also contain every sound your computer currently is playin, because it remixes the output stream into the input stream.

I have created a charater pointer which points to
a string . I need to copy an existing string in the
char pointer i created so i did this
In my class the code is as
char *m_FileName;<br />
m_FileName=new char[strlen(FileName)]; <br />
strcpy(m_FileName,FileName);
In the destructor of the class
<br />
~Class_temp()<br />
{<br />
if(m_FileName!=NULL)<br />
delete []m_FileName;<br />
}
I get a error at the delete keyword ,

am i wrong some where

This won't work coz it's an array of memory.

When using new[] you MUST always use delete[], no matter if you allocate an array of char.
|
|
|
|
|
FileName is a zero-terminated string and strlen returns the number of charachters WITHOUT counting the '\0' char. When you allocate your new string, you need to allocate for one extra character otherwise when you make the copy, the ending zero will be written outside the boudaries of your allocated memory.
Instead of
m_FileName=new char[strlen(FileName)];
Write:
m_FileName=new char[strlen(FileName)+1];
|
|
|
|
|
You should allocate space for one more character than the length of the string:
m_FileName = new char[strlen(FileName)+1];
Also you should initialize m_FileName to NULL in the constructor:
m_FileName = NULL;
this is this.
|
|
|
|

Yeh i initialised
m_FileName = NULL;
but thanks for the suggestion that i should
add one more memory space for termination
charater .
But it dont work to solve my problem

Hello,
After the modification of the +1, your code should work. Are you modifying the string elsewhere?

Also either call
memset(m_FileName,0,(strlen(FileName)+1));
after the new,
or call
m_FileName[strlen(FileName)] = '/0';
after strcpy.
These sort of issues are commonly caused by the program not seeing the end of the string and it overruns it's buffer.
Another possible issue is if you are assigning a pointer to that string elsewhere that is still using it. Check the debugger to ensure anything that needs to reference the string stored in m_FileName after it's deleted has made it's own copy.
eg. code like this is BAD
class MyClass
{
private:
char* mystring;
public:
void SetMyString(const char* const newstring) { mystring = newstring; }
};
void somefunction()
{
MyClass mc;
const char* conststring = "test me"
char* addstring = new char*[strlen(conststring)+1];
memset(addstring, 0, strlen(conststring)+1); // strlen(conststring)+1 could be assigned to an integer
strcpy(addstring, conststring);
mc.SetMyString(addstring);
delete[] addstring; // BAD - because mc now contains an invalid pointer!!!!!
}

Nope. strcpy will copy the terminating zero so you don't need to do it yourself.

OK, I didn't think it did. I've been programming for about 20 years but not a lot of C until recently

Cedric, actual problem is that.. vikas is allocating memroy many time and deleting memory only one time... let me explain that by small example...
class MemLeak
{
char *pFile;
public:
void allocatemem()
{
pFile=new char[100];
}
~MemLeak()
{
if(pFile)
delete []pFile;
}
};
In this case it will work fine
MemLeak a;
a.allocatemem() ;
and on destruction 100 byte will deleted so no Memory leak, but let me consider a another case
MemLeak a;
a.allocatemem() ;
a.allocatemem() ;
so on destruction only 100 byte is freed so there is memory leak. i believe vikas can code something like this
class MemLeak
{
char *pFile;
public:
MemLeak()
{
pFile=NULL;
}
void allocatemem()
{
if(pFile)
delete [] pFile;
pFile=new char[100];
}
~MemLeak()
{
if(pFile)
delete []pFile;
}
};

We don't know if he allocates the memory several times or not. But something that is sure is that this is not the source of the crash: allocating several times memory without freeing it lead to memory leaks but it won't crashes for sure. So the problem must be somewhere else...
But still, your suggestion is good: memory leaks are a bad programming practice

You are Right (as Always).. But i believe original author never mention there is crash , here is original comment from vikas :-
I get a error at the delete keyword ,
Damage After normal Block 0x00000034
am i wrong some where
this type of error/message usually occur when there is memroy leak...
[ot] anyways... Hows your Xmas prepartion going on.... Marry Xmas
