No MDI borders?

[Jacob]

I'm trying to create an MDI form where the MDI area dosn't have the
traditional 3D borders. I thought at one point the code I had in the form
constructor was working, but now I'm getting an MDI without borders, but the
main menu on my form no longer appears. Anybody who has a little more
experience with this and is willing to help, I would appreciate it.

Thanks,
Jacob

// In MDI form constructor, after InitializeCompo nent.
for(int i = 0; i < this.Controls.C ount; i++)

{

mdiClient = Controls[i] as System.Windows. Forms.MdiClient ;

if(mdiClient != null)

{

// Get Styles using Win32 calls

int style = Win32.GetWindow Long(mdiClient. Handle, Win32.GWL_STYLE );

int exStyle = Win32.GetWindow Long(mdiClient. Handle, Win32.GWL_EXSTY LE);

// Remove any borders on the Mdi.

style &= ~Win32.WS_BORDE R;

exStyle &= ~Win32.WS_EX_CL IENTEDGE;
// Set Styles using Win32 calls

Win32.SetWindow Long(mdiClient. Handle, Win32.GWL_STYLE , style);

Win32.SetWindow Long(mdiClient. Handle, Win32.GWL_EXSTY LE, exStyle);

break;

}

}

Well, I think I got it figured out. When the code is placed in the
constructor it fails because the form and hence the MdiClient have not
gotten bounds yet. Without bounds, the function treats the whole form as the
mdi area, leaving no room for the menu, and that is what is causing the menu
to disappear.

Just put the code in the load event or other appropriate spot.

Oh ya, you'll need to force the MdiClient to be recreated. Placing this
directly after the first snippet is one way.


Win32.SetWindow Pos(mdiClient.H andle, IntPtr.Zero, 0, 0, 0, 0,

Win32.SWP_NOACT IVATE | Win32.SWP_NOMOV E | Win32.SWP_NOSIZ E |
Win32.SWP_NOZOR DER |

Win32.SWP_NOOWN ERZORDER | Win32.SWP_FRAME CHANGED);
