64-Bit Scrolling

[Guest Jonathan Wood]

I noticed that all documentation for the SCROLLINFO structure (used with

SetScrollInfo) just uses int or UINT for structure members as opposed to

INT_PTR.

 

Does this mean 64-bit Windows does not support 64-bit scroll values?

 

I have an application where the scroll range and position could exceed 32

bits. Has anyone already worked out the algorithm to make this work on

Win32?

 

Thanks.

Ahhh, I'm rusty, but on a 64bit system isn't the INT 64bit wide?

 

Also, this 'group' is mostly a GUI (General User Issues) forum, you might

search out a developer hangout.

No, I believe int will continue to be 32-bits. At least, why would MS come

up with all the INT_PTR, DWORD_PTR, etc. types?
