MessageBox with YesNoCancel - No & Cancel triggers same event

此生再无相见时 提交于 2019-11-28 17:46:19
I have a message box with the YesNoCancel buttons... Pressing Yes will do some action and close the application - works fine Pressing No will do nothing and close the application - (see below) Pressing Cancel will do nothing and keep the application open - (see below). I'm using DialogResult.No for the No button and DialogResult.Cancel for the Cancel button. But pressing either of them triggers DialogResult.Cancel event. What's the problem? Darin Dimitrov This should work fine: Dim result As Integer = MessageBox.Show("message", "caption", MessageBoxButtons.YesNoCancel) If result = DialogResult

在CTreeCtrl控件点击事件中获取点击的项

守給你的承諾、 提交于 2019-11-28 14:59:24
网上搜了一下,有两种方法: 1、使用GetSelectedItem() HTREEITEM hItem = m_treeCtrl.GetSelectedItem(); CString strText = m_treeCtrl.GetItemText(hItem); MessageBox(strText); 2、使用HitTest() CPoint pt; GetCursorPos(&pt); m_treeCtrl.ScreenToClient(&pt); UINT uFlags; HTREEITEM hItem = m_treeCtrl.HitTest(pt, &uFlags); CString strText = m_treeCtrl.GetItemText(hItem); MessageBox(strText); 总结:方法没有达到要求,因为在点击事件使用GetSelectedItem()获取的项是CTreeCtrl控件选中的项,并不一定是点击的项,因为它只会返回上次点击的项,因为上次点击的项在这次事件中是出于选中状态的,因此使用方法2. 来源: http://www.cnblogs.com/lit10050528/p/4141852.html

Detecting creation of a MessageBox

妖精的绣舞 提交于 2019-11-28 12:49:54
问题 My application is loading 3rd party DLLs, and some of this DLLs open MessageBox windows. Is there a way for me to detect when such a window was being opened? 回答1: You'll need a CBT hook to receive a notification when a MessageBox window is displayed. You install this by calling the SetWindowsHookEx() function and specifying WH_CBT for the hook ID parameter. The hook callback function will provide you a handle to the MessageBox window, which you can then use to close it. If you know exactly

How to customize message box

情到浓时终转凉″ 提交于 2019-11-28 06:55:53
I am doing C# application, and I want to change the style of a message box. Is it possible or not? Example: change button style, fore color, etc. You can't restyle the default MessageBox as that's dependant on the current Windows OS theme, however you can easily create your own MessageBox. Just add a new form (i.e. MyNewMessageBox) to your project with these settings: FormBorderStyle FixedToolWindow ShowInTaskBar False StartPosition CenterScreen To show it use myNewMessageBoxInstance.ShowDialog(); . And add a label and buttons to your form, such as OK and Cancel and set their DialogResults

Produce “toast” messages like StackOverflow

One of the issues I think about every time I build my web application is how messages should appear to the end-users I tried message boxes like those in windows applications, but they look so bad and make problems when published on the server. I've tried an update panel containing a cool label at the top of bottom of my page..but still i feel it's not good enough at all. Sometimes I have problems in specific cases when using AJAX, and it still doesn't look good for the users... I want to ask about the StackOverFlow messages that appear for a while and then disappear, for example the message
