自定义MessageBox
我想创建一个自定义消息框，但我想在显示消息框中使用自定义图标和自定义声音如何创建此消息框？ 我不想使用shell32.dll和user32.dll
与Windows XP的Windows 7相同的消息框
我使用了一个带有静态方法ShowCustomButtonsDialog的简单对话框。 我在左上角放置了一个文本标签，并将边框样式更改为Dialog。 方法只返回按钮索引或-1。
public partial class CustomButtonsDialog : Form { private const int ButtonHeight = 24; private const int ButtonPadding = 6; private const int ButtonInnerPadding = 5; private const int MaxFormWidth = 700; private int buttonIndex = -1; public int ButtonIndex { get { return buttonIndex; } private set { buttonIndex = value; } } public static int ShowCustomButtonsDialog(string text, string title, params string[] buttonsText) { var dlg = new CustomButtonsDialog(text, title, buttonsText.ToList()); dlg.ShowDialog(); return dlg.ButtonIndex; } public static int ShowCustomButtonsDialog(string text, string title, List buttonsText) { var dlg = new CustomButtonsDialog(text, title, buttonsText); dlg.ShowDialog(); return dlg.ButtonIndex; } public CustomButtonsDialog() { InitializeComponent(); } private CustomButtonsDialog(string text, string title, List buttonsText) { InitializeComponent(); Text = title; labelText.Text = text; // добавить кнопки var formWidth = ClientSize.Width; List buttonWidths; using (var gr = CreateGraphics()) { buttonWidths = buttonsText.Select(b => (int)gr.MeasureString(b, Font).Width + 2 * ButtonInnerPadding).ToList(); } var totalButtonWd = buttonWidths.Sum() + (buttonWidths.Count - 1) * ButtonPadding; if (totalButtonWd > formWidth) { if (totalButtonWd <= MaxFormWidth) Width = Width - ClientSize.Width + totalButtonWd + ButtonPadding * 2; else {// trim some buttons Width = Width - ClientSize.Width + MaxFormWidth; totalButtonWd = ClientSize.Width - ButtonPadding * 2; var avgWidth = (totalButtonWd - (buttonsText.Count - 1) * ButtonPadding) / buttonsText.Count; var sumThins = buttonWidths.Sum(w => w <= avgWidth ? w : 0); var countThins = buttonWidths.Count(w => w <= avgWidth); var countFat = buttonsText.Count - countThins; var spareRoom = totalButtonWd - sumThins; var fatWidth = (countThins == 0) || (countFat == 0) ? avgWidth : (spareRoom - (countThins - 1)*ButtonPadding)/countFat; for (var i = 0; i < buttonWidths.Count; i++) if (buttonWidths[i] > avgWidth) buttonWidths[i] = fatWidth; } } // buttons' Y-coords and height labelText.MaximumSize = new Size(totalButtonWd, labelText.MaximumSize.Height); var buttonTop = labelText.Bottom + ButtonPadding; var formHeight = buttonTop + ButtonHeight + ButtonPadding; Height = Height - ClientSize.Height + formHeight; // do make buttons var buttonLeft = ButtonPadding; var tag = 0; for (var i = 0; i < buttonWidths.Count; i++) { var button = new Button { Parent = this, Width = buttonWidths[i], Height = ButtonHeight, Left = buttonLeft, Top = buttonTop, Text = buttonsText[i], Tag = tag++ }; button.Click += ButtonClick; buttonLeft = button.Right + ButtonPadding; Controls.Add(button); } } private void ButtonClick(object sender, EventArgs e) { ButtonIndex = (int) ((Button) sender).Tag; Close(); } } 最简单的方法是从头开始创建自己的MessageBox窗口。 如果您正在寻找默认窗口MessageBox的钩子，您需要考虑以后可能会遇到与其他Windows操作系统兼容的问题。
