Help Hiding Maximize Button on Form

I am trying to hide >> JUST << the Maximize button.
I want the Minimize and Close to still show up and work.

This is what I tried. The call to GetWindowLong() always
returns Zero as the value.

Thanks,
Dave


// ------------------------------------------

[DllImport("user32.dll")]
static extern long GetWindowLong(long hwnd, long nIndex);

[DllImport("user32.dll")]
static extern long SetWindowLong(long hwnd, long nIndex, long dwNewLong);

// ------------------------------------------

private void mainForm_Load(object sender, System.EventArgs e)
{
// Set up additional information
InitializeForm();
}

// ------------------------------------------
private void InitializeForm()
{
const int WS_MAXIMIZEBOX = 0x10000;
const long GWL_STYLE = -16;

long hWnd = this.Handle.ToInt32();
long style = GetWindowLong(hWnd, GWL_STYLE);

style = style & ~WS_MAXIMIZEBOX;
SetWindowLong(hWnd, GWL_STYLE, style);
this.Invalidate();
}

Click to expand...

There is no way to hide the button, but you can disable it by setting the
form's 'MaximizeBox' property to 'False'.
