  • Any way to get TStringList.CommaText to not escape commas with quotes?

    - by Mason Wheeler
    I'm doing some work with code generation, and one of the things I need to do is create a function call where one of the parameters is a function call, like so: result := Func1(x, y, Func2(a, b, c)); TStringList.CommaText is very useful for generating the parameter lists, but when I traverse the tree to build the outer function call, what I end up with looks like this: result := Func1(x, y, "Func2(a, b, c)"); It's quoting the third argument because it contains commas, and that produced invalid code. But I can't do something simplistic like StringReplace all double quotes with empty strings, because it's quite possible that a function argument could be a string with double quotes inside. Is there any way to make it just not escape the lines that contain commas?

  • Silverlight Line Graph with Gradient

    - by gav
    I have a series of points which I will turn into a line on a graph. What I want is to give the area under the graph a gradient fill. It would look somewhat similar to a Bloomberg graph like this; My question really has three parts; First, how should I fill only the area under the graph? Second, how do I fill that with a gradient? Finally, if I have multiple lines on the same graph any area under more than one line should have a greyscale gradient fill, how would you set this up? My biggest problem is deciding on the data structures to use, I could use many multiple sided shapes (One for each line/ data series) and then tell the brush to draw; Transparent if it's not in any shape The colour of one series if it's in one shape (Alpha relative to height to give grad) Black if it's in multiple shapes (Alpha relative to height to give grad) Then I'd draw the shapes' boundaries in white afterwards. Thanks, Gav

  • How can I store data in a table as a trie? (SQL Server)

    - by Matt
    Hi, To make things easier, the table contains all the words in the English dictionary. What I would like to do is be able to store the data as a trie. This way I can traverse the different branches of the trie and return the most relevant result. First, how do I store the data in the table as a trie? Second, how do I traverse the tree? If it helps at all, the suggestion in this previous question is where this question was sparked from. Please make sure it's SQL we're talking about. I understood the Mike Dunlavey's C implementation because of pointers but can't see how this part (The trie itself) works in SQL. Thanks, Matt

  • Jquery Live Validation

    - by sico87
    Hello Everyone, After having a search around I could not find exactly what I want, I am looking to validate a form client side using the Jquery library and some form of validation plugin. I was hoping that some one could advise me on whether there are any validation plugins out there that do not use generic error messages, as my form is laid out with no room for these errors, and I also I want the validator to to for correct content as well. Basically I want to be able to check the field on each key press and blur and if the fields validates for it to gain a green border, and if it does not validate for it to gain a red border, any one know of a plugin that can do this? Thanks sico87

  • How can I link glibc statically with qt

    - by yan bellavance
    I have built a static version of qt and download a static version of glibc. Now I would like to link glibc statically to my qt application. I know about going into the .pro and adding the line LIBS += -L path/to/static_lib but I am wondering if these that is enough? Will it still link glibc statically even though the OS I am building on has the dynamic libraries also? The reason I am doing this is to deploy the application in a standalone manner. (After installing and updating Red Hat 5.3 glibc_2.9 was not found on the target computer)

  • Form invalidate() in WinForms Application

    - by Pramodh
    i need to animate an object in c# windows application int l_nCircleXpos = 9, l_nCircleYpos = 0; private void Form1_Paint(object sender, PaintEventArgs e) { Graphics l_objGraphics = this.CreateGraphics(); Pen l_circlePen = new Pen(Color.Blue); SolidBrush l_circleBrush = new SolidBrush(Color.Blue); l_objGraphics.DrawEllipse(l_circlePen, l_nCircleXpos, l_nCircleYpos, 30, 30); l_objGraphics.FillEllipse(l_circleBrush, l_nCircleXpos, l_nCircleYpos, 30, 30); Pen l_rectPen = new Pen(Color.Red); } private void timer1_Tick(object sender, EventArgs e) { l_nCircleXpos++; l_nCircleYpos++; } private void timer2_Tick(object sender, EventArgs e) { Invalidate(); } but in timer2 its invalidating the entire form. i need to invalidate the specific circle area only. please help to do this in a better way

  • Resharper and var

    - by Refracted Paladin
    I have Resharper 4.5 and have found it invaluable so far but I have a concern; It seems to want to make every variable declaration implicit(var). As a relativly new developer how much should I trust ReSharper when it comes to this? Take the below code snippet from a method that Paints Tab Headers. TabPage currentTab = tabCaseNotes.TabPages[e.Index]; Rectangle itemRect = tabCaseNotes.GetTabRect(e.Index); SolidBrush fillBrush = new SolidBrush(Color.Linen); SolidBrush textBrush = new SolidBrush(Color.Black); StringFormat sf = new StringFormat { Alignment = StringAlignment.Center, LineAlignment = StringAlignment.Center }; Resharper wants me to change all 5 of those to var. I have read the following similar post,Use of var keyword in C#, but I would like to know from a Resharper standpoint. Thanks!

  • Double associative array or indexed + associative array

    - by clover
    I'm undecided what's the best-practice approach for what I'm trying to do. I'm trying to enter data into an array where the data will look like this: apple color: red price: 2 orange color: orange price: 3 banana color: yellow price: 2 pineapple color: yellow price: 5 When I get input, let's say green apple (notice it's a combo of color + name of fruit), I'm going to check if the name of fruit part exists in the array and display its data (if it exists). What's the right way to compose those arrays? How would I do an indexed array containing an associative array? (or would this be better as 2 nested associative arrays, I'm guessing not)

  • TreeView nodes always have .Checked=true on postback even when not checked in UI

    - by GISmatters
    I have a treeview in my .aspx: <asp:TreeView ID="tvDocCatAndType" runat="server" /> Not much else going on in the page -- two <asp:LinkButtons> and one <asp:Label>; the page is a child of a master page, so these controls are within a <asp:Content> control. I populate the treeview in code -- just 3 node levels, including the root node. All nodes have checkboxes, and I initialize all node.Checked to true. I have some Javascript to do the usual check/uncheck up and down the tree as parent and child node checkboxes are toggled. No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine. Thanks in advance for any helpful comments or questions, Chris

  • How to use ColorDrawable with ImageView?

    - by user246114
    Hi, I have a layout with an ImageView defined like: <ImageView android:layout_width="45dip" android:layout_height="45dip" android:scaleType="fitXY" /> now I just want to set the imageview to be a static color, like red or green. I'm trying: ColorDrawable cd = new ColorDrawable("FF0000"); cd.setAlpha(255); ImageView iv = ...; iv.setImageDrawable(cd); the imageview is just empty though, no color. The 45dip space is being used up though. What do I need to do to get the color to be rendered? Thanks

  • Java: Netbeans debugging session works faster than normal run

    - by Martijn Courteaux
    Hello, I'm making Braid in Netbeans 6.7.1. Computer Spec: Windows 7 Running processes: 46 Running threads: +/- 650 NVidia GeForce 9200M GS Intel Core 2 Duo CPU P8400 @ 2.26Ghz Game-spec with normal run: Memory: between 80 MB and 110 MB CPU: between 9% and 20% CPU when time rewinding: 90% The same values for the debugging session, except when I rewind the time: CPU: 20%. Is there any reason for? Is there a way to reach the same performance with a normal run. This is my repaint code: @Override public void repaint() { BufferStrategy bs = getBufferStrategy(); // numBuffers: 4 Graphics g = bs.getDrawGraphics(); g.setColor(Color.BLACK); g.fillRect(-1, -1, 2000, 2000); gamePanel.paint(g.create(x, y, gameDim.width, gameDim.height)); bs.show(); g.dispose(); Toolkit.getDefaultToolkit().sync(); update(g); } The game runs in fullscreen (undecorated + frame.size = screensize) Martijn

  • Displaying UserControls based on the type a TreeView selection is bound to

    - by Ray Wenderlich
    I am making an app in WPF in a style similar to Windows Explorer, with a TreeView on the left and a pane on the right. I want the contents of the right pane to change depending on the type of the selected element in the TreeView. For example, say the top level in the Tree View contains objects of class "A", and if you expand the "A" object you'll see a list of "B" objects as children of the "A" object. If the "A" object is selected, I want the right pane to show a user control for "A", and if "B" is selected I want the right pane to show a user control for "B". I've currently got this working by: setting up the TreeView with one HierarchialDataTemplate per type adding all the UserControls to the right pane, but collapsed implementing SelectedItemChanged on the TreeView, and setting the appropriate usercontrol to visible and the others to collapsed. However, I'm sure there's a better/more elegant way to switch out the views based on the type the selection is bound to, perhaps by making more use of data binding... any ideas?

  • What are your build and release steps? When to increment build numbers?

    - by Ed
    I am having trouble defining and automating my build process despite simple requirements: Every build should have a unique build number. Every tagged release should be reproducible What I have: A C++, Red Hat Enterprise Linux 5.x, Subversion development environment. A build machine ( actually a virtual machine ) A version.h file with #defines for major, minor, and buildnumber. A script for incrementing the version.h buildnumber. A rpmbuild spec file that exports the tagged Subversion source, builds, and makes the rpm installer packages. Questions: Assuming multiple developers per project, when should the build number be incremented and version.h file be checked-in? The build machine? Some sort of Subversion hook? Pre-build or post-build? Thanks in advance for those willing to take the time to share their experience with build processes. -Ed Linux newbie. Former Windows C++/.NET developer.

  • Is there a way to disable calls to Runtime.checkRestricted on the GAE Java development server under Eclipse?

    - by Thomas Becker
    I'm one of those guys who step through their code a lot during development. Beginning with version 1.6.4 of the GAE Java development server, the server has been instrumented with calls to a function named Runtime.checkRestricted. This causes two inconveniences when I step through my code: 1) Whenever I step into a function, the debugger goes into the function Runtime.checkRestricted (for which there is no source code) at least once, often multiple times. 2) Whenever I step over a function call which has a large call tree underneath it, then it takes a very long time for the debugger to come back. (That's always a problem in the Eclipse Java debugger, but now it's really bad.) For me, all this causes a serious drain on productivity. Is there any way to disable this instrumentation, or to prevent the debugger from stepping into it? I am using Eclipse with the GAE plugin.

  • How to implement filter system in SQL?

    - by sadvaw
    Right now I am planning to add a filter system to my site. Examples: (ID=apple, COLOR=red, TASTE=sweet, ORIGIN=US) (ID=mango, COLOR=yellow, TASTE=sweet, ORIGIN=MEXICO) (ID=banana, COLOR=yellow, TASTE=bitter-sweet, ORIGIN=US) so now I am interested in doing the following: SELECT ID FROM thisTable WHERE COLOR='yellow' AND TASTE='SWEET' But my problem is I am doing this for multiple categories in my site, and the columns are NOT consistent. (like if the table is for handphones, then it will be BRAND, 3G-ENABLED, PRICE, COLOR, WAVELENGTH, etc) how could I design a general schema that allows this? Right now I am planning on doing: table(ID, KEY, VALUE) This allows arbitary number of columns, but for the query, I am using SELECT ID FROM table WHERE (KEY=X1 AND VALUE=V1) AND (KEY=X2 AND VALUE=V2), .. which returns an empty set. Can someone recommend a good solution to this? Note that the number of columns WILL change regularly

  • Unreachable code detected by using const variables

    - by Anton Roth
    I have following code: private const FlyCapture2Managed.PixelFormat f7PF = FlyCapture2Managed.PixelFormat.PixelFormatMono16; public PGRCamera(ExamForm input, bool red, int flags, int drawWidth, int drawHeight) { if (f7PF == FlyCapture2Managed.PixelFormat.PixelFormatMono8) { bpp = 8; // unreachable warning } else if (f7PF == FlyCapture2Managed.PixelFormat.PixelFormatMono16){ bpp = 16; } else { MessageBox.Show("Camera misconfigured"); // unreachable warning } } I understand that this code is unreachable, but I don't want that message to appear, since it's a configuration on compilation which just needs a change in the constant to test different settings, and the bits per pixel (bpp) change depending on the pixel format. Is there a good way to have just one variable being constant, deriving the other from it, but not resulting in an unreachable code warning? Note that I need both values, on start of the camera it needs to be configured to the proper Pixel Format, and my image understanding code needs to know how many bits the image is in. So, is there a good workaround, or do I just live with this warning?

  • Changing the colour of Aero glass for my window?

    - by Roger Lipscombe
    I'm using DwmExtendFrameIntoClientArea in my WPF application to get the glass effect. This is working fine. What I'd like to do is change the colour used for the glass -- I'm writing a countdown timer, and I'd like the window to be the normal glass colour most of the time, and then to go red (but still with glass) when the time runs out. I found this question, which talks about how to apply a gradient glass, and that works fine when picking a different colour. Unfortunately, the borders are not coloured appropriately. When I turn off the borders by using ResizeMode="NoResize", then I end up with square corners. I'd like to keep the rounded corners. I looked at creating an irregularly-shaped window, by using AllowTransparency="True" and that works fine, but doesn't look like an Aero glass window. It looks a bit flat. So: my question: how do I create a window in WPF that looks like Aero glass transparency, but uses a different colour?

    - by PhOeNiX
    How can i validate a ComboBox for null entry? My combobox is in a model as i am generating it dynamically. Now what i want is that when the the columns are generated dynamically, the border of combobox should be red as no value is selected and once the value is selected the border shud become normal. The following is my combobox in model : DataGridTemplateColumn dataGridComboBoxTemplateColumnObj = new DataGridTemplateColumn(); dataGridComboBoxTemplateColumnObj.Header = column.Header; FrameworkElementFactory comboBoxFactory = new FrameworkElementFactory(typeof(ComboBox)); Binding bindingItemSourceObj = new Binding(column.ItemsSourcePropertyName); comboBoxFactory.SetValue(ComboBox.HorizontalAlignmentProperty, HorizontalAlignment.Stretch); comboBoxFactory.SetValue(ComboBox.ItemsSourceProperty, bindingItemSourceObj); comboBoxFactory.SetValue(ComboBox.SelectedValuePathProperty, column.ValuePropertyName); dataGridComboBoxTemplateColumnObj.CellTemplate = new DataTemplate(); dataGridComboBoxTemplateColumnObj.CellTemplate.VisualTree = comboBoxFactory;

  • Website Sitemaps and <priority>, is it working?

    - by Mike Gleason jr Couturier
    Hi, My "Privacy Policy" page is seen more important by Google than other really more important pages on my website. I'm currently creating a script to generate a sitemap, should I bother with the priority? How do you effectively assign priorities to pages? I consider one of my page important but the page have less content than another one less important to my eyes... but maybe Google bot will see it the other way around. If my degree of "importantness" differs from the one of Google, will I get penalized on the ranking for a particular page? Thank you for sharing your black art with us :P

  • How do I build mDNSResponder?

    - by Alex
    I have tried checking out the mDNSResponder source from Apple's SVN host, with the thought of compiling it and tweaking it. This failed miserably. Here is the last line of the output of cd trunk SRCROOT=. make I get the same error for several tags in the SVN tree, so I'm not sure if there is something on my end wrong?

  • What do the different columns (of letters) mean for the svn merge output?

    - by James
    The output of SVN merge has 4 columns of letters listed before the file name. I understand the meaning of the letters (mostly) but I can't find any information on the meanings of the columns and so only have a vague understanding based on context. Can anyone point me to the documentation on this? Based on context I've been able to infer that column: Is about text changes to a file Seems to be related to use of the svn ignore command on a folder (or maybe it's just properties of the file?) I've never seen a letter in the third column and hence I have no idea what it means. Might be tree conflicts? This is the one I'm mostly worried about because I don't know how to handle it yet.

  • Adding Java packages to GWT

    - by Organiccat
    I've tried searching but couldn't come up with a defined way on how to add your own packages to a GWT project. My tree structure looks like this: -com.mycompany -public MyApplication.html MyApplication.gwt.xml -com.mycompany.client MyApp.java -com.mycompany.gui TableLayout.java The answer I've seen out there says to add the packages relative to the root directory of the gwt.xml file, like so: <module> <inherits name="com.google.gwt.user.User" /> <entry-point class="com.mycompany.client.MyApp" /> <source path="client" /> <source path="gui" /> </module> It then complains: Unable to find type 'com.technicon.client.MyApp' Hint: Previous compiler errors may have made this type unavailable Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly Can anyone tell me what I'm doing wrong and how to fix this?

  • SICP making change

    - by RyanD
    So; I'm a hobbiest who's trying to work through SICP (it's free!) and there is an example procedure in the first chapter that is meant to count the possible ways to make change with american coins; (change-maker 100) = 292. It's implemented something like: (define (change-maker amount) (define (coin-value n) (cond ((= n 1) 1) ((= n 2) 5) ((= n 3) 10) ((= n 4) 25) ((= n 5) 50))) (define (iter amount coin-type) (cond ((= amount 0) 1) ((or (= coin-type 0) (< amount 0)) 0) (else (+ (iter amount (- coin-type 1)) (iter (- amount (coin-value coin-type)) coin-type))))) (iter amount 5)) Anyway; this is a tree-recursive procedure, and the author "leaves as a challenge" finding an iterative procedure to solve the same problem (ie fixed space). I have not had luck figuring this out or finding an answer after getting frustrated. I'm wondering if it's a brain fart on my part, or if the author's screwing with me.
