Please don't cross post...
Just add the library under project properties/linker/additional libraries.
Slep.....1
* C:\Program Files\OpenCV\cv\include
* C:\Program Files\OpenCV\cxcore\include
* C:\Program Files\OpenCV\otherlibs\highgui
Give project properties/(C/C++)/General/aditional include Directories
Step2:
cxcore.lib
cv.lib
highgui.lib
Give project properties/linker/Input/additional dependence
Step3:
"C:\Program Files\OpenCV\lib"
Give project properties/linker/General/additional library directories
step4:
#include "cv.h"
#include "cxcore.h"
#include "highgui.h"
(OR)

I know this forum doesnt discuss about errors encountered while using opencv libraries in vs, but I am unable to find any related forum. It would be helpful if someone helps me out.
#include "stdafx.h"
#include <cv.h>
#include <cxcore.h>
#include <highgui.h>
int hsw = 0, hi = 0, lsw = 0, li = 0;
void swh(int p)
{
hi = p;
}
void swl(int p)
{
li = p;
}
int _tmain(int argc, _TCHAR* argv[])
{
int n = 7;
IplImage* img = cvLoadImage( "img1.jpeg", 0 );
IplImage* img_b = cvCreateImage( cvSize(img->width+n-1,img->height+n-1), img->depth, img->nChannels );
IplImage* out = cvCreateImage( cvGetSize(img_b), IPL_DEPTH_8U, img_b->nChannels );
CvPoint off = cvPoint((n-1)/2,(n-1)/2);
cvCopyMakeBorder(img,img_b,off,IPL_BORDER_REPLICATE,cvScalarAll(0));
cvNamedWindow("Canny Edge Detection",1);
int as = n;
double lt = 20;
double ht = 40;
cvCreateTrackbar( "High", "Canny Edge Detection", &hsw, 4, swh );
cvCreateTrackbar( "Low", "Canny Edge Detection", &lsw, 4, swl );
while( 1 ) {
switch( hi ){
case 0:
ht = 200;
break;
case 1:
ht = 400;
break;
case 2:
ht = 600;
break;
case 3:
ht = 800;
break;
case 4:
ht = 1000;
break;
}
switch( li ){
case 0:
lt = 0;
break;
case 1:
lt = 100;
break;
case 2:
lt = 200;
break;
case 3:
lt = 400;
break;
case 4:
lt = 600;
break;
}
// Edge Detection
cvCanny( img_b, out, lt*n*n, ht*n*n, as );
cvShowImage("Canny Edge Detection", out);
if( cvWaitKey( 15 ) == 27 )
break;
}
cvReleaseImage( &img );
cvReleaseImage( &img_b );
cvReleaseImage( &out );
cvDestroyWindow( "Canny Edge Detection" );
return 0;
}
This is my code. When I run it, I get the following error :
The procedure entry point cvCreateTrackbar could not be located in the dynamic link library libcv200.dll.
Where am I going wrong? How should I correct it

This program helps to find out list of members/Nodes under each node.
For example: Tree Chart
A
B C D
E F G
H I
J
Answer:
The Total No. of Nodes under A is: 9
The Total No. of Nodes under B is: 5
The Total No. of Nodes under C is: 0
The Total No. of Nodes under D is: 1
The Total No. of Nodes under E is: 3
The Total No. of Nodes under F is: 0
The Total No. of Nodes under G is: 0
The Total No. of Nodes under H is: 0
The Total No. of Nodes under I is: 1
The Total No. of Nodes under J is: 0

Many of the companies in business today are still following the traditional ins-outs system on paper. And this can create some problems for employees. You don’t need to note down your in time or out time if you implement employee time tracking software. This is software that can help you in maintaining the records of projects and employees’ working hours in an effective manner.
For more information about , visit on link: http://www.project-drive.net/
Our telephone and web-based employee time clock system is totally optimized for the web (unlike typical client/server technology). As a result, our system is fast and very easy to use.

Thanks for sharing these codding, PHP Development India I have tired to find that finally I got it.Quote:
