What is a dword?

[Vikki]

I've got all my errors solved but I may have miss converted the wparam and lparam of SendMessage.

What is the Aurora equivalent of a dword?  I used int but maybe it should be unsigned int?

[Bruce Peaslee]

This is how I declare it:

Code Select Expand


declare import,SendMessage alias SendMessageA(
hwnd as unsigned int, // handle to receiving window
uMsg as unsigned int, // the message
wParam as unsigned int,       // additional info depending on message
lParam as unsigned int         // additional info depending on message
), unsigned int;   // result depending on message

Thanks Bruce!

A DWORD is an unsigned int.

If you get confused with Window's types (and i think we all do at some stage) you can use these handy typedefs:

Basically, you include the file presented in the thread above and declare the Win32API commands as you see them on MSDN.com. So for example your code would be:

Code Select Expand


#include "WindowsTypes.inc"

declare import, SendMessage alias SendMessageA(
HWND hWnd,
UINT Msg,
WPARAM wParam,
LPARAM lParam
), LRESULT;


To implement your 'SendMessage' function:

Got the file in my include folder now. Your work is much appreciated.
