예제

다음 예제에서는 SetDesktopLocation, LoadActivate 멤버를 사용 하는 방법을 보여 줍니다.The following example demonstrates how to use the SetDesktopLocation, Load and Activate members. 예제를 실행 하려면 Button1 이라는 단추가 포함 된 Form1 이라는 폼과 Label1Label2 라는 두 개의 Label 컨트롤에 다음 코드를 붙여넣습니다.To run the example, paste the following code in a form called Form1 containing a button called Button1 and two Label controls called Label1 and Label2.

static int x = 200;
static int y = 200;
void Button1_Click( System::Object^ sender, System::EventArgs^ e )
{
   
   // Create a new Form1 and set its Visible property to true.
   Form1^ form2 = gcnew Form1;
   form2->Visible = true;
   
   // Set the new form's desktop location so it  
   // appears below and to the right of the current form.
   form2->SetDesktopLocation( x, y );
   x += 30;
   y += 30;
   
   // Keep the current form active by calling the Activate
   // method.
   this->Activate();
   this->Button1->Enabled = false;
}


// Updates the label text to reflect the current values of x 
// and y, which was were incremented in the Button1 control's 
// click event.
void Form1_Activated( Object^ sender, System::EventArgs^ e )
{
   Label1->Text = String::Format( "x: {0} y: {1}", x, y );
   Label2->Text = String::Format( "Number of forms currently open: {0}", count );
}

static int count = 0;
void Form1_Closed( Object^ sender, System::EventArgs^ e )
{
   count -= 1;
}

void Form1_Load( Object^ sender, System::EventArgs^ e )
{
   count += 1;
}
static int x = 200;
static int y = 200;

private void Button1_Click(System.Object sender, 
    System.EventArgs e)
{
    // Create a new Form1 and set its Visible property to true.
    Form1 form2 = new Form1();
    form2.Visible = true;

    // Set the new form's desktop location so it  
    // appears below and to the right of the current form.
    form2.SetDesktopLocation(x, y);
    x += 30;
    y += 30;

    // Keep the current form active by calling the Activate
    // method.
    this.Activate();
    this.Button1.Enabled = false;
}



// Updates the label text to reflect the current values of x 
// and y, which was were incremented in the Button1 control's 
// click event.
private void Form1_Activated(object sender, System.EventArgs e)

    ' Set the new form's desktop location so it appears below and 
    ' to the right of the current form.
    form2.SetDesktopLocation(x, y)
    x += 30

설명

폼을 활성화 하 앞으로 보냅니다 활성 애플리케이션 되었거나 활성 애플리케이션이 없는 경우 창 캡션을 깜박입니다.Activating a form brings it to the front if this is the active application, or it flashes the window caption if this is not the active application. 이 메서드가 효과를 적용 하려면 폼이 표시 되어야 합니다.The form must be visible for this method to have any effect. 애플리케이션에서 활성 폼을 확인 하려면 사용 합니다 ActiveForm 속성 또는 ActiveMdiChild 양식은 다중 문서 MDI (인터페이스) 애플리케이션의 경우 속성입니다.To determine the active form in an application, use the ActiveForm property or the ActiveMdiChild property if your forms are in a Multiple-document interface (MDI) application.
