I want to put the image captured by the camera into a picture control.

The code I used is this : errno_t memcpy_s(void *dest,size_t destSize,const void *src,size_t count);

I guess I need to define dest, destSize, src, and count separately here.

so I’d like to know how to do that.

this is whole context :

#include "stdafx.h"
#include "BaslerCode.h"
#include <pylon/PylonIncludes.h>
#include <iostream>
#include "resource.h"
#include "CImageEventHandler.h" 

void BaslerCode::OnImageGrabbed(CInstantCamera& camera, const CGrabResultPtr& ptrGrabResult)
{
     if (ptrGrabResult->GrabSucceeded())
    {
        formatConverter.OutputPixelFormat = PixelType_Mono8;
        formatConverter.Convert(imageRGB, ptrGrabResult);
    
        CImage img;
        img.Create(imageRGB.GetWidth(),imageRGB.GetHeight(), 8); 
        
        errno_t memcpy_s (void *dest,size_t destSize,const void *src,size_t count);

        // dest = 
        // destSize =
        // src = 
        // count = 

        CWnd* pPictureBox = AfxGetApp()->GetMainWnd();
        CDC* pDC = pPictureBox->GetDC();

        CRect rect;                        

        pPictureBox->GetClientRect(&rect); 
    
        img.StretchBlt(pDC->m_hDC,0,0,rect.Width(),rect.Height(),SRCCOPY);

        pPictureBox->ReleaseDC(pDC);
    }

When debugging with this code, the entire screen goes black beyond the picture control.

Any help would be appreciated.
