#include cv.h #include highgui.h #include <stdio.h> int main(int argc, char* argv[]){ cvNamedWindow(Window1, CV_WINDOW_AUTOSIZE); IplImage*

#include 'cv.h' #include 'highgui.h' #include <stdio.h>   int main(int argc, char* argv[]){     cvNamedWindow('Window1', CV_WINDOW_AUTOSIZE);     IplImage* image = 0;     ->->image = cvLoadImage(argv[1]);<-<-     if(!image) printf('Unable to load image!');     cvShowImage('Window1', image);     char c = cvWaitKey(0);     cvReleaseImage(&image);     cvDestroyWindow('Window1');     return 0; }

If I replace the indicated line with cvLoadImage('247.png') I get a blank window and image remains equal to zero

If I run the exe and give it 247.png as an argument, it’s just dandy. If I put the ‘247.png’ right into the code and build and run it Visual Studio 2008, it fails. If I build and run from the command prompt, it works.

Why is this? I’m a little bit weary of moving forwards without getting this down.

  1. Under Project->Properties->Configuration Properties->Debugging there is a field ‘Working Directory’. Set that to the directory you want to execute in and that should fix the problem.
