Hi, I'm still new in this OpenCV, may I know why my above program cannot run properly? This is some of the error I get...thanks...

[Moschops]

blobs = CBlobResult( img, NULL, 10 0, NULL ); //store detected objects

And what is blobs? Is it an int? A double? A float? A string? You have to create objects before you can use them. How is the compiler supposed to know what kind of object this is?

Likewise img and dfont.

Thanks...

Got any library for CBlobResult, CBlobGetXCenter, blob_current, blobs, final_blobs? TQ

[Moschops]

A library won't help. You need to create them. Here is how you would create an int:
int x;

Whatever this blobs thing is meant to be, you'll have to create it. Time to read the manual.
