The problem is that stdlib.h does not define the std namespace, it is the standard C library header. You should include cstdlib for use of the std namespace features.

One of these days I'm going to think of a really clever signature.

Difficult to guess without more information; take a look at the header file to see how it is declared.

Throw VC6 in the bin, it's long past its useby date.

Thanks. Yes, That's right! we are slowly moving to VS2010. But at this point of time we are in a situation to use

std::abort();

in both VC6 and VS2010. This compiles well in VS2010 but my concern is why its not in VC6. Any idea would be helpful.

Why not just use abort()? Adding the namespace prefix buys you nothing.

Ok. Sorry for not explaining that the code piece 'std::abort()' is part of third party and we cannot modify it.

Then contact the third party and tell them to fix it. I assume that you have paid for this code in which case it is their responsibility to provide a fully working solution.

With the amount of information you have provided about this code it is difficult to make any better suggestions.

Thanks for your help.

I found a soultion to this problem.

#if _MSC_VER <=1200
namespace std
{
    using ::abort;
}
#endif

This way we can make 'std' namespace to refer global abort(). It doesn't require to modify 3rd party.

How to print file inclusion stack in VC6

Hi, Is there a way to print file inclusion stack/order in VC++6.0.

In VC10, we can print file inclusion stack in debug window using /showIncludes compiler switch. But same switch is not recognized in VC6.

hi every one this is my first post here in fact i'm confused little bit cause i got to finish a project that i haven't started yet i need to capture image with directshow
in fact i haven't understand directshow very well it's questions and pin ... difficult to grasp for the first time .
the second point if i need a window in which i have to put my components should i create it by hand (from scratch by code ) IVideoWindow ?? and what about list & button ??

let me know

DShow isn't as intimidating as it looks

You create an IFilterGraph, add the filters you want, then create a ICaptureGraphBuilder2, point it at the IFilterGraph, and ask it to RenderStream

You don't really have to worry about pins unless you intend to write your own source or transforms

As regards IVideoWindow, yes, create your own child window and point IVideoWindow at it

There are numerous examples kicking around

Take a look at GraphEdit tool, where you can drag and drop several filters and test it. Or you can just drag and drop a Avi file into graphedit, immediately it will show the filters and connections.

Also take a look at sample direct show filters (comes with dxsdk) . Start with simple BallFilter http://msdn.microsoft.com/en-us/library/windows/desktop/dd318194(v=vs.85).aspx[^]

It seems the mentioned forum is a better place for my question.

Isn't this possible?
Should I repost my question and delete this one?

C++/MFC solution Convert string to integer only such that if it is alphanumeric or float it should show as invalid values.

Hi All,

I want to covert a string to integer in MFC.Consider the string as char str[10]; and integer as int num; My case is as following:-
1) Suppose str = "10"
num should be = 10
2) Suppose str = "10.88"
num should be 0 or any invalid number so that we can identify that its not an integer but any other value.
3) Suppose str = "10ab"
num should be 0 or any invalid number so that we can identify that its not an integer but any other value.

Is there any direct API by which we can identify the above cases. I have tried atoi() but it returns the remaining integer value after removing the float or alphanumeric values.
Or
I have to try it by creating my own method.

You could use strtol()[^] and its variants, as it will give you a pointer to the character that stops the scan of the string. You can then check this character and decide what actions to take. I do not know of any MFC class that offers a more comprehensive solution, but a search of the MFC library should tell you.

Not sure if this is applicable to MFC, but the stringstream library will do this:

C++

#include <iostream>
#include <sstream>

int main( )
{
   std::string inString( "10.88" );
   int outNum;

   std::stringstream ss( inString );

   ss >> outNum;

   std::cout << "As Number [" << outNum << "]" << std::endl;
}

Sample output would be:

As Number [10]

This will not work, you cannot read a floating point variable and correctly store it in an integer variable.

You could simply use atoi() to convert to an integer, then format that value to a string and compare to your original string.

Since you are not asking for anything super efficient or elegant, this should do the trick.

C++

CString	str = "10.88";

int nValue = atoi(str);

CString strValue;
strValue.Format("%d", nValue);
if (strValue != str)
{
    nValue = 0;
}

CString str=10.27;
CString res = str.SpanIncluding(_T("0123456789"));

if(res == str)
{
int nValue = atoi(str);
}
else
{
MessageBox("string is not integer");
}

Visual Studio 10 Linker

I am working on a solution that has only 1 project. If I build the selection, all runs well. If I try to build the Solution (F7), I get an 1120 linker error.

I can see the names of previous functions/classes that have come and gone; I think that the linker is trying to find them to link to them. I have even done a character search of the machine but can't find these functions or the classes that used to contain them.

I am a newbee and this is above my pay grade, all the other hieroglyphics in the error message mean something to someone, but I am afraid that I am lost.

Anyone have any ideas on how to correct this situation? Is there a file(s) that I can "dump" and then just rebuild?

Thanks,

Barry
