For some reason, I try to call AdjustWindowRect, or GetClientRect, and the parameters I provide are fine. I get around 30 errors, none of which relate to the call to the WinAPI function.
What could cause such a thing?
Thanks
For example:
The following code:
case WM_GETMINMAXINFO:
{
LPMINMAXINFO p_info = (LPMINMAXINFO)lParam;
RECT rc = {0,0,d->w,d->h};
DWORD dwStyle = GetWindowLongPtr( hWnd, GWL_STYLE ) ;
AdjustWindowRect(&rc,dwStyle,FALSE);
int total_border_width = 2 * GetSystemMetrics( SM_CXFRAME ) + 4;
int total_border_height = 2 * GetSystemMetrics( SM_CYFRAME ) +
GetSystemMetrics( SM_CYCAPTION ) - GetSystemMetrics( SM_CYBORDER ) + 5;
POINT min,max;
min.x = d->min_w > 0 ? d->min_w + total_border_width : p_info->ptMinTrackSize.x;
min.y = d->min_h > 0 ? d->min_h + total_border_height : p_info->ptMinTrackSize.y;
max.x = d->max_w > 0 ? d->max_w + total_border_width : p_info->ptMaxTrackSize.x;
max.y = d->max_h > 0 ? d->max_h + total_border_height : p_info->ptMaxTrackSize.y;
p_info->ptMinTrackSize = min;
p_info->ptMaxTrackSize = max;
}
Produces:

Visual C++ only supports C90 (not C99), so when compiling a C program, you must place all variable declarations at the top of the block, before any statements.
The declarations of
min,max,total_border_heightandtotal_border_widthall come after at least one statement in the block.
