问题 Microsoft Access text boxes can be configured as "Rich Text", allowing the user to apply formatting such as bold text or different font sizes. Internally, this "rich text" is stored as HTML. Since the formatting options provided by Access are limited, it is obvious that only a subset of HTML is used for storing the formatted text. Is there a list somewhere describing which subset of HTML is used? Ideally, I'd like to have a list of tags that could be found in a text field formatted using this

问题 I have a list of words. The list contains about 100-200 text strings (it's names of metro stations actually). I want to make an auto-complete textbox. For an example, user press 'N' letter, then an (ending of) appropriate option appear (only one option). The ending must be selected. How to do that?

问题 I'd like to modify the spacing between characters in a WPF TextBox. Something like the letter-spacing: 5px thing that is available in CSS. I think it is possible in XAML; what's the simplest way? I found the "Introduction to the GlyphRun Object and Glyphs Element" document, and found it to be exceedingly unhelpful. This is a code example from that page: <!-- "Hello World!" with explicit character widths for proportional font --> <Glyphs FontUri = "C:\WINDOWS\Fonts\ARIAL.TTF"

问题 I'm writing a program where the user should be able to write text in a textbox. I'd like the textbox to resize itself, so it fit the content. I've tried the following: private void textBoxTitle_TextChanged(object sender, TextChangedEventArgs e) { System.Drawing.Font myFont = new System.Drawing.Font("Verdana", 8); System.Drawing.SizeF mySize = e.Graphics.MeasureString("This is a test", myFont); this.textBoxTitle.Width = (int)Math.Round(mySize.Width, 0); } I get an error saying that Graphics

问题 I'm trying to make a number input. I've made so my textbox only accepts numbers via this code: function isNumber(evt) { evt = (evt) ? evt : window.event; var charCode = (evt.which) ? evt.which : evt.keyCode; if (charCode > 31 && (charCode < 48 || charCode > 57)) { return false; } return true; } But now the question comes to, how would I create spaces as the user is typing in their number, much like the iPhone's telephone spacing thing, but with numbers so for example if they type in: 1000 it

问题 I'm fairly new to VB.net (self taught) and was just wondering if someone out there could help me out with some code. I'm not trying to do anything too involved, just have a TextBox that accepts a numeric value from 1 to 10. I don't want it to accept a string or any number above 10. If someone types a word or character an error message will appear, telling him to enter a valid number. This is what I have; obviously it's not great as I am having problems. Thanks again to anyone who can help. If

问题 In Visual C# when I click a button, I want to load another form. But before that form loads, I want to fill the textboxes with some text. I tried to put some commands to do this before showing the form, but I get an error saying the textbox is inaccessible due to its protection level.

问题 instead of using <input type="file"> , is it possible to use <input type="text"> and then script it using javascript or jquery such that when the text box is clicked, the file upload dialogue shows up.....(and have it actually uploaded when it's submitted into a form) 回答1: You mean something like this? http://jsfiddle.net/CSvjw/ $('input[type=text]').click(function() { $('input[type=file]').trigger('click'); }); $('input[type=file]').change(function() { $('input[type=text]').val($(this).val()
