Examples

The following code example demonstrates how to use the ISupportInitialize interface to initialize three TrackBar controls.

(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar1))->BeginInit();
(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar2))->BeginInit();
(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar3))->BeginInit();
this->SuspendLayout();

// 
// trackBar1
// 
this->trackBar1->Location = System::Drawing::Point( 160, 400 );
this->trackBar1->Name = "trackBar1";
this->trackBar1->TabIndex = 1;
this->trackBar1->Scroll += gcnew System::EventHandler( this, &Form1::trackBar_Scroll );

// 
// trackBar2
// 
this->trackBar2->Location = System::Drawing::Point( 608, 40 );
this->trackBar2->Name = "trackBar2";
this->trackBar2->TabIndex = 2;
this->trackBar2->Scroll += gcnew System::EventHandler( this, &Form1::trackBar_Scroll );

// 
// trackBar3
// 
this->trackBar3->Location = System::Drawing::Point( 56, 40 );
this->trackBar3->Name = "trackBar3";
this->trackBar3->TabIndex = 3;
this->trackBar3->Scroll += gcnew System::EventHandler( this, &Form1::trackBar_Scroll );
(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar1))->EndInit();
(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar2))->EndInit();
(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar3))->EndInit();

((System.ComponentModel.ISupportInitialize)(this.trackBar1)).BeginInit();
