问题 This is more of a PHP question than a WordPress question, but I am using it in a WP theme. In my options I am allowing users to show/hide breadcrumbs. However, when there are no preferences yet selected and saved (for example, if somebody were to install the theme) the breadcrumbs aren't displayed by default... and I would like them to be. Below is my code. I'm confident I'm just missing a very small piece of code here... Here is the array I am using: array( "name" => "Display breadcrumbs on

问题 I'm wondering if there is a way in silverlight to set a placeholder value for a combo box. The behavior I wish to achieve is such that when the combo box has no selection, a placeholder value is shown. This value shouldn't be displayed when the user clicks to open the list of values, and if the selected index is cleared, the placeholder value is shown again. Thanks! 回答1: Have a look at this How to display default text "--Select Team --" in combo box on pageload in WPF? and this Silverlight 4

问题 My question is similar to "Android Studio" debugging - display variables as hexadecimal, but I want to know how to make this the default setting. I know how to change the setting for individual values: but for checking the values of all the characters in long strings, this becomes tedious.

I looked in File > Settings > Debugger but I didn't see anything. 回答1: Right

问题 I have a web app that exports reports to Excel. It does this by sending the HTML of the report table to the clipboard, and then pasting it into Excel. Quick and dirty. And it comes through fairly well. Numbers are formatted as numbers, dates as dates, and so on. But the reports have negative numbers formatted to use parentheses rather than a minus sign, and when this is pasted into Excel, it changes to a minus sign. You can see this in action simply by typing (200) into Notepad, and then

问题 Is it possible to set an .ashx file as the starting (or default) page for a web application? If so, how is it done? Edit - Some good suggestions. I have added "Default.ashx" to the IIS Default Documents and "Enabled Default Document" on the website, however, it only displays a directory listing even though I have disabled directory browsing.

问题 I am following this tutorial on setting my app as the default SMS app, but for some reason, my app does not appear in the list of available options. I have tried to research this as much as possible, but everything points back to that same tutorial, or is outdated. Do I need a <receiver> as well? Can someone explain what I am doing wrong?
