  • onfocus with select box in scriptaculous

    - by Stacia
    I have some code like so: $('product_name').onfocus=function() { this.focused=true; }; $('product_name').onblur=function() { this.focused=false; } function getEnter(evt){ if (evt.keyCode == Event.KEY_RETURN) { if ($('product_name').focused ) { ... However, if I try to add this to a select box and change the function to an ||, it breaks. Do select boxes work differently since they can be continuously selected? .focus seemed to make a difference (brighter color when in focus). I am trying to do a search on enter if either the product_name or the select box is focused and do something else otherwise. I have it set up now so everything works except the select box. Thanks.

  • Draw polygon using mouse on google maps

    - by Kunal
    I need to draw polygon using mouse and mark a particular area on google maps. The purpose is to mark an area on google maps and then showing hotels and attractions on that area. The user will mark the hotels on google map while creating them so the db will have their latitude and longitudes. How can I draw the polygon and fill it with a color as background to mark the area in Google Maps? I have read the API Manual “how to draw polygons?” basically you would need to mark multiple points and then combine them into a polygon. But I will need to do this using mouse drag, just like drawing a shape. Kindly help me out how to achieve this. Thanks in advance.

  • Funniest code names for software projects

    - by furtelwart
    Developers are creative. Not as they create wonderfull GUIs or proof their sense for art with good color combinations, but with code names. Every project has a code name, sometimes official, sometimes private (with a good reason!). Here are my favourites: Android: 1.6 = Donut 2.0 = Eclaire (picture of Google's eclaire) grml (Live distribution based on Debian GNU/Linux, comes from Austria therefore in German) Hustenstopper (cough stopper) Eierspass (egg fun) Meilenschwein (mile pig, it's a pun with milestone) Lackdose-Allergie (lacquer can allergy, it's a pun with lactose allergy) Hello-Wien (pun with Halloween, Wien being German for Vienna) I really like to see the funniest code names you ever heard of. Aren't there any more funny project names?

  • Adjusting sql statement in a function based upon input

    - by Stefan
    Hey there, This is a bit urgent! I'm trying to make a simple filter search where-by you can choose from a series of 3 drop downs and then based upon this the results are then displayed, How would I go about adjusting the sql query for each and if you were to only choose to search from aone of the 3 rather than all 3 etc... example there could be the url with input such as: url.com?location=gb&color=3&hair=4 and still form the correct sql query for something like this: url.com?location=gb&hair=1 and not encounter problems with WHERE and AND etc etc and empty variables in the statement Would this not need to be a massive function to check using if to see how the data is set for all possibilities? Thanks, Stefan

  • Having trouble with Regular Expression and Ampersand

    - by ajax81
    Hi All, I'm having a bit of trouble with regex's (C#, ASP.NET), and I'm pretty sure I'm doing something fundamentally wrong. My task is to bind a dynamically created gridview to a datasource, and then iterate through a column in the grid, looking for the string "A&I". An example of what the data in the cell (in template column) looks like is: Name: John Doe Phone: 555-123-1234 Email: [email protected] Dept: DHS-A&I-MRB Here's the code I'm using to find the string value: foreach(GridViewRow gvrow in gv.Rows) { Match m = Regex.Match(gvrow.Cells[6].Text,"A&I"); if(m.Success) { gvrow.ForeColor = System.Drawing.Color.Red; } } I'm not having any luck with any of these variations: "A&I" "[A][&][I]" But when I strictly user "&", the row does turn red. Any suggestions? Thanks, Dan

  • How to compare 2 similar strings letter by letter and highlight the differences?

    - by PowerUser
    We have 2 databases that should have matching tables. I have an (In-Production) report that compares these fields and displays them to the user in an MS-Access form (continuous form style) for correction. This is all well and good except it can be difficult to find the differences. How can I format these fields to bold/italicize/color the differences? "The lazy dog jumped over a brown fox." "The lazy dog jumped over the brown fox." (It's easier to see the differences between 2 similiar text fields once they are highlighted in some way) "The lazy dog jumped over a brown fox." "The lazy dog jumped over the brown fox. " Since we're talking about a form in MS Access, I don't have high hopes. But I know I'm not the first person to have this problem. Suggestions?

  • mouseOver event-mapping on iPad Safari with webkit-user-select: none

    - by Tim
    I don't have an iPad yet to find this out; have had only a brief opportunity to look at one at the Apple store. Could someone please describe what, if anything, happens to the mouseOver event of an image-map area when the image-map|area has had user-select disabled with "webkit-user-select: none" in the CSS, as described here in section 5: http://developer.apple.com/safari/library/technotes/tn2010/tn2262/index.html When a finger tip is placed on the image-map area and held there (i.e.not a tap) is the mouseOver eventhandler invoked under those circumstances? Or does nothing happen other than the image-map area doesn't change color because it's now unselectable? In my brief experience with the iPad at the Apple store, when user-select is not disabled, and the image-map area has a mouseOver eventhandler, a tap fires the mouseOver event rather than the click event. Thanks

  • Table image not showing, "Pop an autorelease pool" error

    - by Graeme
    hi, I have a UITableView which uses the following code to display an image in a Table View cell: cell.imageView.layer.masksToBounds = YES; cell.imageView.layer.cornerRadius = 5.0; UIImage *image = [UIImage imageNamed:[[color types] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; if ( image ) { cell.imageView.image = [image imageScaledToSize:CGSizeMake(50, 50)]; } It works fine on the iPhone simulator, but when I try it on a real iPhone the iPhone doesn't show. Instead in the console in debugging mode, I get this error: attempt to pop an unknown autorelease pool (0x851e00) Any help would be great, thanks.

  • MinGW Doesn't Generate an Object File When Compiling

    - by Nathan Campos
    I've just bought a new laptop for me on the travel, then on my free time, I've started to test MinGW on it by trying to compile my own OS that is written in C++, then I've created all the files needed and the kernel.cpp: extern "C" void _main(struct multiboot_data* mbd, unsigned int magic); void _main( struct multiboot_data* mbd, unsigned int magic ) { char * boot_loader_name =(char*) ((long*)mbd)[16]; /* Print a letter to screen to see everything is working: */ unsigned char *videoram = (unsigned char *) 0xb8000; videoram[0] = 65; /* character 'A' */ videoram[1] = 0x07; /* forground, background color. */ } And tried to compile it with g++ G: g++ -o C:\kernel.o -c kernel.cpp -Wall -Wextra -Werror -nostdlib -nostartfiles -nodefaultlibs kernel.cpp: In function `void _main(multiboot_data*, unsigned int)': kernel.cpp:8: warning: unused variable 'boot_loader_name' kernel.cpp: At global scope: kernel.cpp:4: warning: unused parameter 'magic' G: But it don't create any binary file at C:/.

  • Using CSS gradient instead of images

    - by Wiika
    Using CSS for creating gradients instead of images, does it have any negativity? For example the following code: #gradient { color: #fff; height: 100px; padding: 10px; /* For WebKit (Safari, Google Chrome etc) */ background: -webkit-gradient(linear, left top, left bottom, from(#00f), to(#fff)); /* For Mozilla/Gecko (Firefox etc) */ background: -moz-linear-gradient(top, #00f, #fff); /* For Internet Explorer 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#FF0000FF, endColorstr=#FFFFFFFF); /* For Internet Explorer 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#FF0000FF, endColorstr=#FFFFFFFF)"; } Thanks.

  • Semi-transparent PNG Image on transparent Form

    - by Marco Bruggmann
    Hello, I have a problem dealing with transparent images on transparent Forms. I have been trying and looking for a solution but nothing useful came up. The problem is: I have a Form, this Form has a Panel and the Panel has a PictureBox. Form and Panel are transparent. Now, if the image of the PictureBox has no semi-transparent it works. But if there is a gradient transparency then the "transparent color" is shown. I need the Panel and the PictureBox, so the PerPixelAlpha does not apply for this case. The Form will also have more Controls that should be visible and non transparent (just the PNG image should be transparent). The image below shows: [Left] When the Panel is not transparent. [Center] When the Panel is transparent. [Right] Desired effect (done with PerPixelAlpha). http://www.freeimagehosting.net/uploads/3937fe974d.jpg THX Marco

  • Personalization in ASP.Net MVC -- friendly URLs, and skinning

    - by larryq
    Hi everyone, I haven't delved into custom generation of friendly URLs in ASP.Net MVC, and was wondering if anyone had suggestions. For example, if John Smith were to create an account on www.example.com, I'd like for his homepage to read www.example.com/JohnSmith -- along with the option for him to choose his URL. The ideal is for this to happen with no intervention on my part in the route maps. Also, does anyone have guidelines on good ways to go to customize an MVC site based on URL? Again, using example.com I'd like for John to choose a color theme and logo for his homepage, then apply it accordingly. Thanks for your tips and suggestions.

  • Form for Telerik RadRibbonBar?

    - by Cyclone
    I got the Telerik RadRibbonBar for free with the Express edition of vb a while back, but it did not come with any sort of form. It also, unfortunately, has the control buttons there automatically. How would I create a form which is resizable, and works like a standard winform, but doesn't have the top bar? I tried: FormBorderStyle = Sizable Text = Nothing ControlBox = False Unfortunately, when you maximize the window, it goes in front of the taskbar...and it has an ugly border when it isn't maximized. How can I: Change border color? Make it so it does not go in front of the taskbar? Thanks for the help! I'm surprised there is not some sort of form already made for this.

  • Java image conversion to RGB565

    I try to convert image to RGB565 format. I read this image: BufferedImage bufImg = ImageIO.read(imagePathFile); sendImg = new BufferedImage(CONTROLLER_LCD_WIDTH/*320*/, CONTROLLER_LCD_HEIGHT/*240*/, BufferedImage.TYPE_USHORT_565_RGB); sendImg .getGraphics().drawImage(bufImg, 0, 0, CONTROLLER_LCD_WIDTH/*320*/, CONTROLLER_LCD_HEIGHT/*240*/, null); Here is it: Then I convert it to RGB565: int numByte=0; byte[] OutputImageArray = new byte[CONTROLLER_LCD_WIDTH*CONTROLLER_LCD_HEIGHT*2]; int i=0; int j=0; int len = OutputImageArray.length; for (i=0;i<CONTROLLER_LCD_WIDTH;i++) { for (j=0;j<CONTROLLER_LCD_HEIGHT;j++) { Color c = new Color(sendImg.getRGB(i, j)); int aRGBpix = sendImg.getRGB(i, j); int alpha; int red = c.getRed(); int green = c.getGreen(); int blue = c.getBlue(); //RGB888 red = (aRGBpix >> 16) & 0x0FF; green = (aRGBpix >> 8) & 0x0FF; blue = (aRGBpix >> 0) & 0x0FF; alpha = (aRGBpix >> 24) & 0x0FF; //RGB565 red = red >> 3; green = green >> 2; blue = blue >> 3; //A pixel is represented by a 4-byte (32 bit) integer, like so: //00000000 00000000 00000000 11111111 //^ Alpha ^Red ^Green ^Blue //Converting to RGB565 short pixel_to_send = 0; int pixel_to_send_int = 0; pixel_to_send_int = (red << 11) | (green << 5) | (blue); pixel_to_send = (short) pixel_to_send_int; //dividing into bytes byte byteH=(byte)((pixel_to_send >> 8) & 0x0FF); byte byteL=(byte)(pixel_to_send & 0x0FF); //Writing it to array - High-byte is second OutputImageArray[numByte]=byteH; OutputImageArray[numByte+1]=byteL; numByte+=2; } } Then I try to restore this from resulting array OutputImageArray: i=0; j=0; numByte=0; BufferedImage NewImg = new BufferedImage(CONTROLLER_LCD_WIDTH, CONTROLLER_LCD_HEIGHT, BufferedImage.TYPE_USHORT_565_RGB); for (i=0;i<CONTROLLER_LCD_WIDTH;i++) { for (j=0;j<CONTROLLER_LCD_HEIGHT;j++) { int curPixel=0; int alpha=0x0FF; int red; int green; int blue; byte byteL=0; byte byteH=0; byteH = OutputImageArray[numByte]; byteL = OutputImageArray[numByte+1]; curPixel= (byteH << 8) | (byteL); //RGB565 red = (curPixel >> (6+5)) & 0x01F; green = (curPixel >> 5) & 0x03F; blue = (curPixel) & 0x01F; //RGB888 red = red << 3; green = green << 2; blue = blue << 3; //aRGB curPixel = 0; curPixel = (alpha << 24) | (red << 16) | (green << 8) | (blue); NewImg.setRGB(i, j, curPixel); numByte+=2; } } I output this restored image. But I see that it looks very poor. I expected the lost of pictures quality. But as I thought, this picture has to have almost the same quality as the previous picture. - Is it right? Is my code right?

  • Python "draw() must be called with Label instance as first argument (got _WindowMetaclass instance i

I'm pretty sure I know what I have to do (find how to get Label's instance) just not how to do it. Could someone help me understand how to make this work?

  • How to keep the highlight border of a JComponent, when custom border is set

    - by Frederik Wordenskjold
    I have a JTextField, where I've set some custom properties: nameField.setPreferredSize(new Dimension(275,40)); nameField.setBackground(bgColor); nameField.setForeground(txtColor); nameField.setFont(new Font("HelveticaNeue",Font.PLAIN,22)); nameField.setBorder(BorderFactory.createLineBorder(Color.WHITE, 2)); When the component has focus, there is no highlight shown around the field. On a Mac, it is usually a blue glowing rectangle, indicating that this component has focus. If I comment out the nameField.setBorder(...), the highlight reappears. How do I keep the highlight, but also my custom border!? Basically, I just want the highlight-border to show when the component has focus, and no border when the component is unfocused.

  • Using an NSButtonCell with template image in a NSTableView

    - by alloy
    In Interface Builder, I have set the dataCell of one of the columns of my NSTableView instance to be NSButtonCell. This works as expected, however, trying to use a ‘template’ image doesn't yield the expected visual result when clicking the button. How I configure the NSButtonCell: Image: NSRevealFreestandingTemplate Scaling: None Bezel: Bevel Type: Momentary Push In Bordered: false Expected result when clicking the button: Since the image is a ‘template’, the button should render its ‘on’ state. The background, ie the space surrounding the image, should not change. Actual result when clicking the button: No difference in the ‘state’ of the rendered image. The background color changes to white. Even-though I’ve tried my best to make the explanation of the problem as concise as possible, I’ve also made a simple screencast to visually illustrate the problem. And uploaded the demo app.

  • Viewing HTML inside Applet without using JEditorPane

    - by Tom
    Hello, I have a small (500kb) swing applet that displays very simple/limited set of small HTML page(s) inside it with JEditorPane, however this does not seem to work 100% fluently, some customers get a blank page displayed without any java exceptions. The page works OK from my machine. I need a more reliable way to show HTML page to all our users. Any ideas if there is a small + free class to use instead of JEditorPane OR is there an easy fix to make it more reliable (non blank) private JEditorPane m_editorPane = new JTextPane(); m_editorPane.setEditable( false); m_editorPane.setBackground(new Color(239 ,255, 215)); m_editorPane.setBounds(30,42,520,478 ); m_editorPane.setDoubleBuffered(true); m_editorPane.setBorder(null); m_editorPane.registerEditorKitForContentType("text/html", "com.xxxxx.SynchronousHTMLEditorKit"); m_editorPane.setPage(ResourceLoader.getURLforDataFile(param.trim()));
