I wrote:

CImage image;
image.Load(str_path); // just change extension to load jpg
CBitmap bitmap;
bitmap.Attach(image.Detach());
m_Btn1.SetBitmap(bitmap);
m_Btn1.ShowWindow(SW_SHOW);

str_path is the path of the file jpg

What I have tried:

The image isn't loaded..I searched on internet and I found the code that I wrote

I would guess it is because the image is not accessible to your program. Either give the image file name an explicit path or run your program in the directory where the image file is located.

Actually, the first thing you should do is check the return of the Load method to verify whether the image was actually loaded or not. It is possible that it was loaded but other logic is prohibiting the button from being displayed.

Yes, I know. I read the documentation on the class. https://learn.microsoft.com/en-us/cpp/atl-mfc-shared/reference/cimage-class?view=msvc-170

I loaded image:

CBitmap bitmap;

bitmap.Attach(image.Detach());

HBITMAP hBitmap6 = (HBITMAP)bitmap.GetSafeHandle();

m_Btn1.SetBitmap(hBitmap6);

but image isn't proportionate to size of button

Your code seems to be correct for loading an image and setting it as the bitmap for your button button. As Rick stated, first check if the path you use is correct and if it is returning something,

Add error handling and debugging statements to your code to check if your 'Load' and 'Attach' functions are returning any error codes -

C++

HRESULT hr = image.Load(str_path);
if (FAILED(hr))
{
    //Display a message or log the error code...
    CString errorMessage;
    image.GetLastErrorDescription(errorMessage);
    AfxMessageBox(errorMessage);
}

if (!bitmap.Attach(image.Detach()))
{
    AfxMessageBox(_T("Failed to attach the bitmap."));
}
