GetWindowLong(int hWnd, GWL_STYLE) return weird numbers in c#

c#

Solution

What is weird about those values? For example, `482344960` is equivalent to `0x1CC00000` which looks like something you might expect to see as a window style. Looking at the styles reference you linked to, that is `WS_VISIBLE | WS_CAPTION | 0xC000000`.

If you wanted to test for `WS_VISIBLE`, for example, you would do something like:

int result = GetWindowLong(theprocess.MainWindowHandle, GWL_STYLE);
bool isVisible = ((result & WS_VISIBLE) != 0);

Problem

I used GetWindowLong window api to get current window state of a window in c#. ``` [DllImport("user32.dll")] static extern int GetWindowLong(IntPtr hWnd, int nIndex); Process[] processList = Process.GetProcesses(); foreach (Process theprocess in processList) { long windowState = GetWindowLong(theprocess.MainWindowHandle, GWL_STYLE); MessageBox.Show(windowState.ToString()); } ``` I expected to get numbers on http://www.autohotkey.com/docs/misc/Styles.htm, but I get numbers like -482344960, -1803550644, and 382554704. Do I need to convert windowState variable?? if so, to what?
