Thank you so much for your advice! I'll try this way and tell you if it works or not.

2020-03-13 05:55:11 -0500 marked best answer How to compile Opencv 3.4.1 program in VS 2019 with Opencv 4.1.1?

I've a program written for Opencv 3.4.1 in order to capture image by basler camera and store it in "IplImage*" type of image then show it in Opencv window. I'm using Visual Studio 2019 with Opencv 4.1.1 and when i compiled it it had some errors:

At "static IplImage* s_pCvSrcImg = NULL;" : Missing type specifier-assumed int.Note: C++ does not support the default -int

memcpy(s_pCvSrcImg->imageData, ptrGrabResult->GetBuffer(), ptrGrabResult->GetImageSize());: Identifier " memcpy" cannot be found

And the same errors for cvCanny ,cvShowImage, cvWaitKey in the below Lines Here is the program:

#define OPENCV
#if defined OPENCV
#include "opencv2/opencv.hpp"
#endif  //#if defined OPENCV
#include <conio.h>
// Include files to use the PYLON API.
#include <pylon/PylonIncludes.h>
#ifdef PYLON_WIN_BUILD
#    include <pylon/PylonGUI.h>
#endif

// Namespace for using pylon objects.
using namespace Pylon;

// Namespace for using cout.
using namespace std;

using namespace GenApi;

// Number of images to be grabbed.

#if defined OPENCV
static char s_szCvWindowNameSrc[64] = "Source";
static char s_szCvWindowNameProc[64] = "Processed";
static IplImage* s_pCvSrcImg = NULL;    //Source image
static IplImage* s_pCvProcImg = NULL;   // Destination image
#endif  //#if defined OPENCV

 int main(int argc, char* argv[])
{
// The exit code of the sample application.
int exitCode = 0;

// Before using any pylon methods, the pylon runtime must be initialized. 
PylonInitialize();

try
{

// Create an instant camera object with the camera device found first.
    CInstantCamera camera( CTlFactory::GetInstance().CreateFirstDevice());
   // Print the model name of the camera.
    cout << "Using device " << camera.GetDeviceInfo().GetModelName() << endl;

    // The parameter MaxNumBuffer can be used to control the count of buffers
    // allocated for grabbing. The default value of this parameter is 10.
    camera.MaxNumBuffer = 5;

    // Start the grabbing of c_countOfImagesToGrab images.
    // The camera device is parameterized with a default configuration which
    // sets up free-running continuous acquisition.
    // camera.StartGrabbing( c_countOfImagesToGrab);
    camera.StartGrabbing(-1);

#if defined OPENCV
    INodeMap& nodemap = camera.GetNodeMap();

    CIntegerPtr width(nodemap.GetNode("Width"));
    unsigned int uiWidth = (unsigned int)width->GetValue();

    CIntegerPtr height(nodemap.GetNode("Height"));
    unsigned int uiHeight = (unsigned int)height->GetValue();

    // Create OpenCV window for mono8
    s_pCvSrcImg = cvCreateImage(cvSize(uiWidth, uiHeight), IPL_DEPTH_8U, 1);
    s_pCvProcImg = cvCreateImage(cvSize(uiWidth, uiHeight), IPL_DEPTH_8U, 1);

    // for change fps automatically 
    CBooleanPtr AcquisitionFrameRateEnable(nodemap.GetNode("AcquisitionFrameRateEnable"));
    AcquisitionFrameRateEnable->SetValue(true);

    CGrabResultPtr ptrGrabResult;

    // Camera.StopGrabbing() is called automatically by the RetrieveResult() method
    // when c_countOfImagesToGrab images have been retrieved.
    int iCount = 0;
    bool bQuit = false;

    while ( false == bQuit )
    {
        // Wait for an image and then retrieve it. A timeout of 5000 ms is used.
        camera.RetrieveResult( 5000, ptrGrabResult, TimeoutHandling_ThrowException);

        //cout << iCount << ", " << endl;
        // Image grabbed successfully?
        if (ptrGrabResult->GrabSucceeded())
        {
#if defined OPENCV
