The BitBlt function performs a bit-block transfer of the color data corresponding to a rectangle of pixels from the specified source device context into a destination device context.

If a rotation or shear transformation is in effect in the source device context, BitBlt returns an error. If other transformations exist in the source device context (and a matching transformation is not in effect in the destination device context), the rectangle in the destination device context is stretched, compressed, or rotated, as necessary.

Summary
The CreateDIBSection function creates a Device Independent Bitmap (DIB) that applications can write to directly. The function gives you a pointer to the location of the bitmap bit values. You can supply a handle to a file-mapping object that the function will use to create the bitmap, or you can let the system allocate the memory for the bitmap.

SQLInstallerError does not post error values for itself. SQLInstallerError returns SQL_NO_DATA when it is unable to retrieve any error information (in which case pfErrorCode is undefined). If SQLInstallerError cannot access error values for any reason that would normally return SQL_ERROR, SQLInstallerError returns SQL_ERROR but does not post any error values. If either the lpszErrorMsg argument is NULL or the cbErrorMsgMax is less than or equal to 0, this function returns SQL_ERROR. If the buffer for the error message is too short, SQLInstallerError returns SQL_SUCCESS_WITH_INFO and returns the correct pfErrorCode value for SQLInstallerError.

        string exportedEventLogFileName = Path.Combine(destinationDirectory, eventLogName + ".evt");

.

As explained [here], memory for the returned unmanaged string must be freed by calling LocalFree. Therefore, you must define the string as an IntPtr in managed code and call LocalFree yourself. Otherwise, the marshaler would call CoTaskMemFree which is not correct in this case.

The CryptSignHash function signs data. Because all signature algorithms are asymmetric and thus slow, the CryptoAPI does not allow data to be signed directly. Instead, data is first hashed and CryptSignHash is used to sign the hash.
