$ E% g9 a6 N, u9 \+ S' LAnswer: - Z: Q2 P' T x% X* JYou can create a form with a client edge overriding the CreateParams function and adding the WS_EX_CLIENTEDGE style to Params.ExStyle.

/ Y# _; l! E2 d0 |% r; {

Step 1: Add the CreateParams prototype to the form class.

Step 2: Code the function.

void __fastcall TForm1::CreateParams(TCreateParams &arams) 0 E( w5 `% G9 Q( B { 0 ?2 g4 E& N0 C" S+ \0 C2 b TForm::CreateParams(Params); // call base class first ! @9 @' B1 `# i' w9 W6 U Params.ExStyle |= WS_EX_CLIENTEDGE; // then add the style }

If you would rather not bother with CreateParams, you can achieve identical results by placing a panel on your form. Set the Aligment property of the panel to alClient, set both BevelInner and BevelOuter to bvNone, and set the panel's BorderStyle property to bsSingle.
