问题 My SQL Server table is updated from outside of my program (from a SQL trigger, actually), so the DataSet doesn't realize that there are changes and my DataGrid doesn't update unless I explicitly call SqlDataAdapter.Fill() again (e.g. with a "Refresh" button or a timed event). Is there a way that ADO.NET can subscribe to change events or such so that it refreshes itself? 回答1: Yes, using Query Notifications. You get a callback when the dataset has changed and you run your query again. 来源： https

问题 I have an intranet I am building, and am learning web languages as I go. I have a basic html/php page that contains an iFrame, which most of my content is loaded into. I also have a login box that is a popup modal within the main page. When you fill in this popup and hit login, it refreshes the main page, so that it knows you are logged in, and can display your name etc etc. However, this means that the iframe SRC also resets to its default. Is there a way to retain whatever the current SRC

问题 In the codepen below I have a Element-UI datepicker set up to show a dynamic disabled dates based on a random number.

问题 I managed to programmatically change my desktop background via this one-liner: DllCall("user32.dll", "int", "SystemParametersInfo", "int", 20, "int", 0, "str", $CmdLine[1], "int", 0) … by drag and drop of the desired wallpaper onto the compiled script. I have another program that changes the desktop but for some reason fails to send the WM_SETTINGCHANGE message (I can see the key HKCU\Control Panel\Desktop\Wallpaper getting updated). How can I send this message to trigger a wallpaper refresh?

问题 This is what I am trying to do: _tableView.data[0].rows[selectedPosY].children[selectedPosX].imageId = tempImageId; _tableView.data[0].rows[selectedPosY].children[selectedPosX].image = tempImageUrl; Titanium.API.info("imageIdSelected:" + _tableView.data[0].rows[selectedPosY].children[selectedPosX].imageId + "imageSelected:" + _tableView.data[0].rows[selectedPosY].children[selectedPosX].image); The update is done on the data, but it doesn't reflect in UI table, what is missing?

问题 I have configured Xcode to use Subversion (hosted on a remote webserver - Beanstalk.com). In Xcode menu under SCM, I want to know the difference between two options 1. "Refresh Entire Project ..." and 2. "Update Entire Project ..." Please help. Thanks Dev. 回答1: Open the SCM Results window from the SCM menu item, click on the little 'text' button on the left-hand-side (might be at the bottom of the window to start with?), expand it so you can see a little more, and then run refresh and update

问题 I noticed that if I move my WPF window through code, I will only see that changes when the window refreshes (if I minimize and then maximize it). Is it possible to refresh the GUI of a WPF on demand? EDIT: I'm actually trying to make this window follow another window. So I'm hooking to the other window's events: m_wndParent = parent; this.Owner = m_wndParent; m_wndParent.SizeChanged += ParentSizeChanged; m_wndParent.LayoutUpdated += ParentLocationChanged; and then I change my window's

问题 I need to refresh my ListView every time the another control's IsChanged event is fired. I googled on how to do that, and I saw a stackoverflow link that led me here One of the answers worked: listView.ItemsSource = listView.ItemsSource Is that really the only way to refresh my ListView ? It feels kinda off. 回答1: Just invalidate it. listView.InvalidateProperty(ListView.ItemsSourceProperty) That ought to do it. As an aside, I would really suggest looking at MVVM. It tends to be much more

问题 I need to know when a user refreshs the page and when he switches to another tab. Does anyone has a clue how to capture this in a firefox extension? Best regards Christian 回答1: What you seem to want is knowing when the value in the location bar changes. This requires implementing nsIWebProgressListener interface. The only method you really need is onLocationChange , rest of them should be dummies. You can find the documentation along with code examples here: https://developer.mozilla.org/en
