VC++: Cast operator not used?

by: A. W. Dunstan |last post by:

I'm porting some code to Visual C++ and have run into a problem - the compiler won't use a user-written cast operator. The code uses an envelope-letter approach to passing (potentially) large pieces of data around, and requires that certain methods return an Envelope with a specific kind of Letter as it's content. I have a cast operator that converts from what I've got to what should be returned, but it seems that the compiler only...

to cast or not to cast malloc ?

by: MSG |last post by:

The answer is neither. Use macros. #define ALLOC(size, type) ((type) *) malloc((size) * sizeof(type)) #define NEW(type, name, size) (type) * (name) = ALLOC((size), (type)) They are both type-safe and concise. Compare: NEW(int, x, 1000);

Why does this object need to be cast?

by: Hazz |last post by:

In this sample code of ownerdraw drawmode, why does the '(ComboBox) sender' line of code need to be there in this event handler? Isn't cboFont passed via the managed heap, not the stack, into this cboFont_DrawItem event handler?

The easy way to turn off automatic updates for Windows 10/11

by: Hystou |last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

AI Job Threat for Devs

by: agi2029 |last post by:

Let's talk about the concept of autonomous AI software engineers and no-code agents.

Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
