CreateThread and ExitThread

Code Snippet: (Sorry if there are errors, because im typing it from scratch)

Code:

void FreezeValue( HWND hWnd )
{
while ( IsDlgButtonChecked( hWnd, ID_CHECKBOX1 ) == BST_CHECKED )
{
DWORD dwWeight = (DWORD)(GetDlgItemInt( hWnd, WEIGHT_EDIT, NULL, FALSE ) );
// You should probably declare your Weight variable globally so you can just do:
// *(DWORD*)dwWeight = ...
Sleep( 50 );
}
ExitThread( 0 );
}

LRESULT CALLBACK WndProc( HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam )
{
//...
case WM_COMMAND:
switch ( LOWORD(wParam) )
{
case ID_CHECKBOX1:
if ( IsDlgButtonChecked( hWnd, ID_CHECKBOX1 ) == BST_CHECKED )
CreateThread( 0, 0, (LPTHREAD_START_ROUTINE)FreezeValue, hWnd, 0, 0 );
break;
}
break;
//...
}

Sorry, I was originally lead to your source to see how the pointer reads values (didn't realize you had that) I don't play maplestory, so I didn't really use it Sad

Thanks for the code snippet lurc. Is IsDlgButtonChecked faster than doing SendMessage? Also, it probably takes up a lot of CPU if I'm doing like 5 threads at once, is there a more efficient way?

I'm pretty sure IsDlgButtonChecked just looks like this:

Code:

UINT IsDlgButtonChecked( HWND hWnd, int nIDButton )
{
return (UINT)SendDlgItemMessage( hWnd, nIDButton, BM_GETCHECK, 0, 0 );
}

I just used it because i didn't feel like adding anything else or typing out SendMessage lol.

What i usually do is just make a macro using #define like so:

Code:

#define GetCheck(hWnd,Id) SendDlgItemMessage( (HWND)(hWnd), (int)(Id), BM_GETCHECK, 0, 0 );

So you could just do:

Code:

if ( GetCheck( hWnd, ID_CHECKBOX1 ) == BST_CHECKED )

And Threads are probably the only safe way. So you'll have to sacrifice your CPU for a couple threads.
