you should refer to this book "Inside C#"

ok thanx ill try to consult the book

you now , there is a OLE/COM Object Viewer in MS visual c++, which can be used to view the type libaray.
I am viewing a huge type library and find it very dificult to locate a specified interface. is there a search tool or something like this to find it quickly?
Thank you very much!!!

I normally just copy the IDL into notepad and do a text search.

Hello!
On the graph display we have many overlapped text. Is there any good algorithms to resolve this problem, so that we have a readable layout ?
Thanks

if its a bar graph, draw the text vertical and not horizontal,

You can just cast it, because they are both the same size.

Gosh.
char * pChar;
unsigned char * pUnsigned = (unsigned char *) pChar;
If you didn't know how to do that, I recommend you read some resources on pointers.

Hi all, I want to use the STL library in my program. When I try to define the vector inside the header file, it gave me an error. Following is my program
// LMRectangle.h file //
#include <vector>
class LMRectangle
{
public:
...
private:
...
vector<vector> _vertexList;
};
The class Vector is a user-defined class. I really need this vector data structure and also other files will need the LMRectangle later, so the _vertexList has to be in the header file. Could somebody tell me a solution about this please??? Thanks very much!!!!

You need to specify the namespace and the template parameter type.
e.g. std::vector<int> _vertexList;

Hi
std::vector this notation solved the problem, but now there is another problem that because the Vector class is user-defined, in the header file, it complains that the Vector is undeclared identifier. I tried to include the Vector.h header file in this header file, but it complains that Vector class is redefined. How should I solve this problem then???
// LMRectangle.h file
#include "Vector.h"
class LMRectangle{
public:
...
private:
...
std::vector<Vector> _vertexList;
}
This is the code.
Thanks very much

What's there in Vector.h?
Regards,
Nish
|

Vector.h contains the definition of the Vector class which I want it to be stored in the
vector<Vector> _vertexList.
Thanks

Okay, you need to #include <vector> as well as your custom "Vector.h". I hope you are doing that.
Now if you are getting an error that Vector is not defined, it probably means, there's something wrong about the way it's defined in Vector.h.
Can you copy/paste the declaration of the class Vector from Vector.h?
Also copy/paste the compiler error message here.
Regards,
Nish

The Vector.h file is something like:
class Vector{
public:
...
private:
...
};
simple like that.
When I defined the LMRectangle.h file like this:
#include "Vector.h"
class LMRectangle{
public:
...
private:
...
std::vector<Vector> _vertexList;
}
I will get the compiler errors
e:\C++ Projects\Topology\Vector.h(3): error C2011: 'Vector' : 'class' type redefinition
e:\C++ Projects\Topology\LMRectangle.h(7): error C2011: 'LMRectangle' : 'class' type redefinition
Otherwise, if I comment out the first line of the LMRectangle.h file, it will generate the following errors;
e:\C++ Projects\Topology\LMRectangle.h(25): error C2065: 'Vector' : undeclared identifier
e:\C++ Projects\Topology\LMRectangle.h(25): error C2955: 'std::vector' : use of class template requires template argument list
e:\C++ Projects\Topology\LMRectangle.h(7): error C2011: 'LMRectangle' : 'class' type redefinition
e:\C++ Projects\Topology\Vector.h(3): error C2011: 'Vector' : 'class' type redefinition
e:\C++ Projects\Topology\Vector.cpp(30): error C2501: 'Vector' : missing storage-class or type specifiers
Thanks

Has "Vector.h" got include guards? The file should look something like this:
<br />
#ifndef __VECTOR_H__<br />
#define __VECTOR_H__<br />
<br />
<br />
#endif // !__VECTOR_H__<br />
The "'class' type redefinition" make we wonder if this is the problem.

Why are you creating a header file just to define a vector ? Does this mean this vector is global ? If so, you should declare it in your stdafx, if you have one ( or better yet, don't make it global ).

Does anyone recall the name of the professional product that maps out a running process and shows which routines are being hit and how frequently? Its on the tip of my tongue. :/ Googling for "process mapping" isn't very concise.
In any case, what I would ideally like to find ( it probably doesn't exist ) is software which identifies all the function calls in a running process, represents them on the screen as colored squares, and colors them accorded to a weighted value ( how frequently that code is hit ). Every time a function is hit its respective box will highlight green. Each box would show the functions address offset.
Dang I can't remember the name of that software....

It's called profiler.
