C#軟體開發例項.私人訂製自己的螢幕截圖工具（六）新增配置管理功能
上一篇：C#軟體開發例項.私人訂製自己的螢幕截圖工具（五）針對拖拽時閃爍卡頓現象的優化
新增設定視窗
在解決方案資源管理器視窗中，右鍵單擊專案名稱，在彈出的選單中選擇：新增》Windows窗體：
輸入窗體名稱“frmSetup”：
設定窗體的Text屬性為“設定”，設定窗體的Size為“472, 276”，StartPosition屬性為“CenterScreen”。
新增設定標籤頁：
左側工具箱》窗器：雙擊“TabControl”
設定的Dock屬性為“Top”，Size屬性為“456, 200”；
新增標籤頁：
新增三個標籤頁，Text分別設定為“基本設定，自動上傳，自動儲存”
新增確定和取消按鈕；
基本設定標籤頁：
從工具箱中新增兩個GroupBox，分別為“熱鍵、截圖選項”；
新增兩個RadioButton，用於熱鍵選擇；
新增四個CheckBox用於截圖選項；
新增兩個TextBox用於設定放大鏡的尺寸；
新增兩個PictureBox用於顯示X和鎖的圖片；
新增圖片資源：
雙擊Properties中的“Resources.resx”
切換到影象檢視：
將圖片複製，貼上到這裡，分別命名為“Lock，X”；
設定PictureBox的Image屬性為對應的資源：
自動上傳標籤頁：
自動儲存標籤頁：
其中檔名稱需要使用兩個ComboBox，Items集合分別設定為：
編寫程式碼：
雙擊設定窗體，切換到程式碼檢視，新增私有變數：
/// <summary>
/// 儲存Form1的控制程式碼
/// </summary>
private IntPtr frm1Handle = IntPtr.Zero;修改建構函式：
/// <summary>
/// 建構函式
/// </summary>
/// <param name="frm1_Handle"></param>
public frmSetup(IntPtr frm1_Handle)
{
InitializeComponent();
this.frm1Handle = frm1_Handle;
}為托盤選單中的設定新增事件處理
開啟主窗體Form1的設計檢視，選中“contextMenuStrip1”
修改設定選單的Name為“tsmi_Set”，雙擊設定選單，新增程式碼：
/// <summary>
/// 托盤選單設定事件處理程式
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void tsmi_Set_Click(object sender, EventArgs e)
{
frmSetup frm = new frmSetup(this.Handle);
frm.ShowDialog();
}新增專案引用：
