sition初始窗口位置CancelButton按下esc键后执行那个按钮。ControlBox确定系统是否
有图标和最大最小关闭按钮。FormBorderStyle指定边框和标题栏的外观和行为。HelpButton确定窗体
的标题栏上是否有帮助按钮。KeyPreview确定窗体键盘事件是否已经向窗体注册。MainMenuStrip
确定键盘激活和多文档合并。ShowInTaskbar确定窗体是否出现在任务栏中。WindowState
确定窗体的初始可视状态。1.1.5窗体的常用方法和事件方法Activate当窗体被激活时候发生M
diChildActivate当MDI子窗体被激活时候发生事件ActivatedClosedClosin
gLoad示例：显示另一窗体示例：显示另一窗体[被调用的窗体类][窗体实例]=new[被调用的窗体类]();[窗
体实例].Show();下面，在菜单的单击事件中写下如下的事件。privatevoidmenuItem3_Click(obj
ectsender,EventArgse){Form2Mdichild=n
ewForm2();Mdichild.MdiParent=this;Md
ichild.Show();}当然，需要再建立两个窗体对象，form2和form3窗体示例1：在form2窗
体中进行如下操作单击“发送”按钮应用程序示例首先，将form2的comboBox1下拉框填充完毕后，增加load事件pr
ivatevoidForm2_Load(objectsender,EventArgse){
comboBox1.SelectedIndex=0;textBox3.Text="
";textBox1.Focus();}其次，添加form2的发送信息事件publ
icvoidbutton1_Click(objectsender,EventArgse){
if(textBox1.Text==""||textBox2.Text==""||comboBox
1.Text==""){MessageBox.Show("姓名，或
者邮件，或者提交，信息禁止为空！","信息提示");}else
{this.Hide();Form3childf
orm3=newForm3(this.textBox1.Text,this.textBox2.Text,this.combo
Box1.SelectedItem.ToString(),this.textBox3.Text);
childform3.Show();}}最后关闭窗体
事件：privatevoidbutton2_Click(objectsender,EventArgse)
{this.Close();}应用程序示例对于form3窗体而言，在系统初始事
件填写如下代码：publicpartialclassForm3:Form{private
string_name;privatestring_emailId;privatest
ring_subject;privatestring_feedBack;public
Form3(stringvarName,stringvarEmail,stringvarSubject,string
varFeedBack){InitializeComponent();
//在private变量中存储值this._name=varName;
this._emailId=varEmail;this._subject=varS
ubject;this._feedBack=varFeedBack;//
在列表框中放置值listBox1.Items.Add("姓名："+this._name);
listBox1.Items.Add("邮件地址："+this._emailId);
listBox1.Items.Add("信息主题："+this._subject);listBox
1.Items.Add("反馈意见："+this._feedBack);}private
voidbutton1_Click(objectsender,EventArgse){
MessageBox.Show("感谢您输入的反馈！");this.Close();
}}示例2：在MDI父窗口中，子窗口如何彼此之间传递信息？代码见下示例3：如何防止重复打开子窗体啊？
方法：直接检测是否已经打开此MDI窗体//是否已经打开了？（用循环来判断）foreach(Formchi
ldrenForminthis.MdiChildren){//检测是不是当前子窗体名称if(childre
nForm.Name=="子窗体名称"){//是的话就是把他显示childrenForm.Visible=
true;//并激活该窗体childrenForm.Activate();return;}}
//下面是打开子窗体Form1childrenForm=newForm1();childrenForm.Mdi
Parent=this;childrenForm.Show();childrenForm.WindowState
=FormWindowState.Maximized;示例4：另一种窗体之间的传值技巧（一）——传单个值1、先在For
m2中定义一个成员变量和一个属性如下：privatestringform2zhi=null;publicstri
ngForm2ChuanZhi{get{returnform2zhi;}}2、再在Form3中定义
一个成员变量和一个属性如下：privatestringform3zhi=null;publicstringFo
rm3ChuanZhi{set{form3zhi=value;}get{returnform
3zhi;}}3、双击btn_ChuanZhi在这个事件中写入以下代码（主要是显示Form3窗体和将Form2中的值
传过去）：Form3form3=newForm3();form3.Form3ChuanZhi=form2zhi
;//将值传过去form3.Show();代码见下示例5：另一种窗体之间的传值技巧（二）——类保存任意值代码见下
Winform界面美化技巧1、从附件资料中确认有第三方动态链接库文件DotNetSkin.dll或者IrisSkin2.dl
l，这两个文件是第三方开发设计的Winform界面美化的主要文件2、打开VS2005，展开工具箱，右键点击界面选择“添加选项卡
”，新建选项卡“皮肤”Winform界面美化技巧4、在工具箱项窗口点击“浏览”，导入第三方动态链接库文件DotNetSkin
.dll或者IrisSkin2.dll，两个dll都是一样的用，不同的是DotNetSkin.dll用的皮肤文件是.skn,Ir
isSkin2.dll是用的.ssk3、在工具箱的新建选项卡“皮肤”里面单击右键，选择“选择项”，将展开选择工具箱项Winf
orm界面美化技巧5、则在工具箱的皮肤选项卡内将出现皮肤控件。5、皮肤文件的基本用法是：拖拽任何一个皮肤控件到某个窗体上面，
进行如下的编码：namespaceporjectname{publicpartialclassForm1
:Form{publicForm1(){Initia
lizeComponent();this.skinEngine1.SkinFile=".ssk";
或是this.skinUI1.SkinFile=".skn";
}
}}Winform界面美化技巧namespaceWindowsApplication1{publicpa
rtialclassForm7:Form{publicForm7(){
InitializeComponent();//this.skinEngine1.
SkinFile=".ssk";//stringpath=Envi
ronment.CurrentDirectory+"\\skn皮肤\\LE4-DEFAULT.skn";
this.skinUI1.SkinFile=path;}}有关ssk文件和skn文件库，请参见附件文件
