For the few forms that slip through the cracks, I don't want the generic "hey look, he made this in visual studio" icon. One solution is to tediously check every one of my forms to make sure they either have a custom icon set or have ShowIcon set to False. Another solution is to have every one of my forms inherit from a base class that sets a custom icon in the constructor. Aside from those solutions, what other options do I have?

I know there is a Form_Load() event, but I do not see a Form_Loaded() event, or the % as a property / attribute anywhere. 回答1: all you need to create one form as splash screen and show it before you main start showing the

Is it possible? Thanks. Maybe this code help u to understand my purpose: private void btnCreateReport_Click(object sender, EventArgs e) {

1.添加一个类class AutoSizeFormClass { //(1).声明结构,只记录窗体和其控件的初始位置和大小。 public struct controlRect { public int Left; public int Top; public int Width; public int Height; } //(2).声明 1个对象 //注意这里不能使用控件列表记录 List nCtrl;，因为控件的关联性，记录的始终是当前的大小。 // public List oldCtrl= new List();//这里将西文的大于小于号都过滤掉了，只能改为中文的，使用中要改回西文 public List<controlRect> oldCtrl = new List<controlRect>(); int ctrlNo = 0;//1; //(3). 创建两个函数 //(3.1)记录窗体和其控件的初始位置和大小, public void controllInitializeSize(Control mForm) { controlRect cR; cR.Left = mForm.Left; cR.Top = mForm.Top; cR.Width = mForm.Width; cR.Height = mForm.Height; oldCtrl.Add(cR);//第一个为

初学 Winform 时，相信很多人都遇到过自己的程序在运行中出现了没有捕获的异常，导致程序退出的问题，在这种情况下，程序往往会弹出一个很不友好的信息框，然后强行退出。 程序出现了未捕获的异常，系统便认为它无法再继续工作了，所以强行结束了程序，这也是很正常的行为。但如果我们想要给用户显示一个比较友好的信息框，或者记录上传错误日志等等，那么就需要添加全局异常处理程序。 要为 Winform 程序添加全局异常处理程序，需要对 UI 线程和其他线程分别处理，代码如下： static class Program { /// /// 应用程序的主入口点。 /// [STAThread] static void Main() { Application.EnableVisualStyles(); // 设置 UI 线程异常处理程序，必须在 Application.Run() 方法之前添加 Application.ThreadException += OnThreadException; // 要捕获其他线程的异常，必须先调用 SetUnhandledExceptionMode() 方法指示程序如何处理异常 Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException); // 设置其他线程异常处理程序

Winform知识点1 1. 窗体组成 1. using System; //系统生成的命名空间 2. using System.Collections.Generic; 3. using System.ComponentModel; 4. using System.Data; 5. using System.Drawing; 6. using System.Text; 7. using System.Windows.Forms; 8. namespace Title //命名空间 9. { 10. public partial class Form1 : Form //Form 类在 System.Windows.Forms 命名空间中 11. { 12. public Form1() //构造方法 13. { 14. InitializeComponent(); //初始化方法 15. } 16. } 17. } 从第1行到第7行是系统自动生成的命名空间，在本例中用到 using System.Windows.Forms。第10行定义的Form1 类是本程序的窗体类，从Form 类继承。类名由窗体的Name属性决定，如果不指定则默认为Form1。 构造方法中惟一的方法―― InitializeComponent()方法。从名字上可以看出，这个方法起到初始化作用。右击

编写WinowsForm应用程序时，实现两个窗体之间相互传递值的方法其实很简单。以下用一个例子说明：在名为FormMain主窗体运行过程中利用名为FormInfo窗体，获取用户输入信息，并将这些信息返回给FormMain 1. FormMain和FormInfo 点击“修改...”按钮，显示FormInfo 2. 设置FormInfo中buttonOK和buttonCancal的属性 3. FormMain代码 public partial class FormMain : Form { public FormMain() { InitializeComponent(); } private void buttonInfo_Click( object sender, EventArgs e) { // 实例化FormInfo，并传入待修改初值 var formInfo = new FormInfo(labelInfo.Text); // 以对话框方式显示FormInfo if (formInfo.ShowDialog() == DialogResult.OK) { // 如果点击了FromInfo的“确定”按钮，获取修改后的信息并显示 labelInfo.Text = formInfo.Information; } } } 4. FormInfo代码 public partial
