dbghelp header file is not supporting into Win32 or SDK Application.

Any one have any idea , how to achieve for "MiniDumpWriteDump" API in Win32 Application.

Can you please describe about scaniro 3 , why its error?

still i am getting the same warning message.

compiler: Visual Studio 2010

SecondLine,which i mention

void *p = operator new[1024];

it gives the following compile time error.

1)void *' differs in levels of indirection from 'std::auto_ptr<_Ty>
2)initializing' : cannot convert from 'overloaded-function' to 'void *
etc...

so what is the proper declaration for operator new?.

ok,

If i create a modal dialog using DoModal(), what are the functions are called internally.

using windbg , i can load dmp file and watch in which place exe is crashed. in DebugDiag ?

pls suggest some other tool apart from windbg, because windbg not able to install in my machine.

I need a tool, which can load the crashdump file and it shows the line number of exe is crashing.

Is there anyway to measure time in microseconds precision in windows

i have small query on that like will DateTime.Now.ToString(). Should print the current timestamp value.

i am getting proper value . format like
DateTime.Now.ToString("HH:mm:ss.fff.ffffff");

not getting proper value while dumping into file

you are not understanding my question.

I need a current time with format like= hour:minute:second:milliseconnds:microseconds.
and not find the difference between two processing time.

ok and apart from logging any other way to find out crashing line?

good question.

currently application is running on production , i can not touch the code to do any changes

yes, i can do that way, but while i put the code in debug mode and cursor is cross this line(sprintf_s(l_Title_ca,"Version %d.%02d [MemberId :- %s]",Ver,Rel,MemID);) .I am gettting the "Assertion Debug Failed!".

message: "buffer too small".

that is correct, actually without any changes in the code, i need to handle the exception.

hello, i could not find the proper answer in Google as per my search.

Base(const Base& obj)
{
m = new int(*obj.m);
}



Here while creating copy constructor , why should i pass reference and why can not value?
and what is the necessary of const in copy constructor?

which scenario should i use Base a = b;

NoI have a query on that, that's why i asked

How? can you explain more about it?

yes

I am able to receive the data

thanks

different process

Dll and exe are running on different process.
No, example exe is running one thread and dll is running another thread. Dll is providing some data/information to exe and at certain point dll needs to intimate to the exe my work is completed.
how to achieve this problem.

thanks man

Do we have any predefined API , which can add currentTime + seconds.

Example: Currnet Time : 10:23:45
here i am adding 60 seconds = 10:24:45

thanks........

ok,anyway thanks for your video for boost library configuration

Could you send me the screen shot for that BOOST LIBRARY configuration.its very helpful for me.

Thanks man...

Could you provide some realtime example in Mutex and Criticalsection.

the Mutex object allows synchronizing objects across the process.

http://www.codeproject.com/Articles/7953/Thread-Synchronization-for-Beginners

for example:
declare int count variable in global;
open the file
if(file Handle != NULL)
do
{
read the line from file
add lines into CString array
count++;

if(count == 11)
add the lines(data) into another array
else if(count == 21)
add the lines(data) into another array
else if(count == 31)
add the lines(data) into another array
else
add the lines(data) into another array.

}while(fileHandle != EOF)


You may try this method....

Have you created modal dialog or modless dialog?
paste the pice of code here.

my self

Yes, I understood your description and where can i use dymanic_cast?, and why i need to do dynamic_cast?

please explain.

ok,

class Test
{
public:
virtual void function()
{
}
};

what is the size of Test class in 32bit machine and 64bit machine?

My question is not related to 64 bit machine and 32 bit machine?

for example:

class Base{
public:
int a;
};


void main()
{
printf("Size of class %d",sizeof(Base));

}

its print 4. because int ocoupy 4 bytes in memory likewise ,i am asking about the VTABLE.

thanks for your comments........

#include<iostream>


using namespace std;

class empty{
public:

virtual void function()
{
}

};

int main()
{

printf ("Size of empty is= %d\n", sizeof(empty));
return 0;
}

I am getting size of empty class is one byte and in a class contain one virtual function ,the size is 8 bytes.how?
any one can explain?

Hi there,
I saw the example, but still the async socket with multithreading should be happen.

give some example
