Right Answer:
To save a Windows bitmap in VC++, you can use the `GetDIBits` function to retrieve the bitmap data and then write it to a file in the BMP format. Here’s a simple outline of the steps:
1. Create a `BITMAPINFO` structure to define the format of the bitmap.
2. Use `GetObject` to retrieve the bitmap information.
3. Call `GetDIBits` to get the pixel data.
4. Open a file and write the BMP header followed by the pixel data.
Here’s a code snippet:
```cpp
void SaveBitmap(HBITMAP hBitmap, const char* filename) {
BITMAP bmp;
GetObject(hBitmap, sizeof(BITMAP), &bmp);
BITMAPFILEHEADER bmfHeader;
BITMAPINFOHEADER bi;
bi.biSize = sizeof(BITMAPINFOHEADER);
bi.biWidth = bmp.bmWidth;
bi.biHeight = bmp.bmHeight;
