Anxious, how to perform single-step execution in vc to watch the line

107028255

I made a vc display image program, but at the end I couldn't draw a picture. When I stepped through the debugging, I found that there was a problem in obtaining the initial address of the data. The first few lines went, and the execution went to the gaze line.Why?
I have a headache because I just learned. Which one can help?

Maybe you updated the code and executed it without compiling

Rebuild it and try again.
