问题 Ext JS base and widgets together offer me the solution I've been looking for. The Ext JS library is somewhat heavy w.r.t. conventional standards. There are several widgets in the library that I am not using. So I want to know if it is possible to remove the corresponding code (of widgets not being used) from the ext-all.js ? To put it in other words, is it possible to compose a master Java Script of Ext JS that comprises of only the widgets of my interest? If there is a way I'd love to know.

问题 I’m using two html canvas, the fronendCanvas is visible to the users and is part of the html DOM tree and is set to have 100% of the window width and height, the backendCanvas is created on the javascript code and is used to contain the huge diagram that I need to draw. /** FrontendCanvas */ // HTML <canvas id="canvas"></canvas> // JavaScript frontCanvas.width = window.innerWidth; frontCanvas.height = window.innerHeight; // CSS #canvas { display: block; background-color: #dddddd; } /**

问题 I've implemented file uploading using WCF's streaming. Everything works as expected, however i faced one issue: i'm allocating 4kb buffer to read from incoming stream, but WCF reads only 255 bytes. Here is my upload function: public UploadResponse UploadFile(FileDto fileDto) { using (var inStream = fileDto.FileStream) using (var outStream = new FileStream("OutFile.txt", FileMode.Create)) { var buffer = new byte[4096]; int count; while ((count = inStream.Read(buffer, 0, buffer.Length)) > 0) {

问题 I have one combo that allows user to select a font name. The 2nd is supposed to show available sizes of the font. The 3rd has to show available styles. Question: how can I retrieve the sizes and styles selected System.Drawing.Font supports? 回答1: You could use the InstalledFontCollection class to retrieve the available fonts and then enumerate them as shown in this MSDN article. InstalledFontCollection installedFontCollection = new InstalledFontCollection(); // Get the array of FontFamily

问题 Is there any extension or tool to check size of Dom. Like firebug have Dom panel, which shows all events and functions declared in a web page, can this show more like size of the object, and in how many millis it gets loaded? I'm looking for a tool to measure all (js)objects in a webpage. Thanks in advance. 回答1: Are you looking for a tool that you can simply run yourself (like Google Chrome's analytic tools) or something you can deploy on your website? If you just need the measurements, I'll

问题 I'm so confused. I don't have a status bar, and I don't know how to make my scroll view's dimensions. Is it 320 x 480, or 320 x 460? Because when I drag it out onto storyboard and it fills the entire screen it says it is 320 x 460, but then when I add subviews to it they get positioned strangely and so that it's like the views are 20 pixels short or something. EDIT: I'm just a little confused because when my status bar goes away, it doesn't re adjust the view size, it just makes the view 20

问题 I am trying to get the physical device size of a connected USB flash drive. I have tried using WMI. ManagementObjectSearcher mosDisks = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive WHERE Model = '" + cmbHdd.SelectedItem + "'"); foreach (ManagementObject moDisk in mosDisks.Get()) { lblCapacity.Text = "Capacity: " + moDisk["Size"]; } I have tried using imports to get the geometry: var geo = new DiskGeometry(); uint returnedBytes; DeviceIoControl(Handle, 0x70000, IntPtr.Zero, 0,

问题 I have an application I am developing in wxPython. Part of the application creates a large number of TextCtrls in a grid in order to enter four-letter codes for each day of the week for an arbitrarily large list of people. I've managed to make it work, but I'm having to do something kludgy. Specifically, I haven't found a good way to figure out how big (in pixels) a bit of text is, so I have to guess at sizing the TextCtrls in order to just fit the biggest (4 letter) code. My concern is that

问题 My application needs to capture some pictures of a given size (lets say WxH) in a portrait orientation mode. In a general case the size WxH I want is not supported by the camera therefore I will need to crop the captured picture in order to match my specifications. This apparently simple program is driving me crazy for the problem of "good" corrispondence among preview and picture sizes and format. Let me explain: I need a format (let's give some numbers: 800x600) for the output image, and I
