  • Format table header

    - by Ryan Erb
    I have a table with slanted text in the header row, the only problem is that the text still makes the width of the columns way to large. Is there any way to squish together the table columns so that they are about the width of the select boxes? Or is there a way to place the text there without it in the header and maybe just use a <div> or <p>? Here is the fiddle I am working with: http://jsfiddle.net/t9Krg/1/ .slanted { -webkit-transform: rotate(-45deg); -moz-transform: rotate(-45deg); -ms-transform: rotate(-45deg); -o-transform: rotate(-45deg); transform: rotate(-45deg); white-space:nowrap; /* display:noblock; */ } The boarders around the header is just to see the extra spacing and will be removed later.

  • Convert a complicated string into an array in php

    - by Patrick Beardmore
    I have a php variable that comes from a form that needs tidying up. I hope you can help. The variable contains a list of items (possibly two or three word items with a space in between words). I want to convert it to a comma separated list with no superfluous white space. I want the divisions to fall only at commas, semi-colons or new-lines. Blank cannot be an item. Here's a comprehensive example (with a deliberately messy input): Variable In: "dog, cat ,car,tea pot,, ,,, ;;(++NEW LINE++)fly, cake" Variable Out "dog,cat,car,tea pot,fly,cake" Can anyone help?

  • How to use a delay in a swing application

    - by M.R.
    I am building a swing application. At some point, I have to start an "animation": ... jpanel1.setBackground(Color.Black); Delay(milli) jpanel1.setBackground(Color.White); ... and so on. The gui itself and all the logic behind it work.It is just this time depended color-changing that does not. I have read, that swing is not thread safe, but all the examples I found showed me how to start another thread (for example in the background) but never how to stop the current swing-gui thread.

  • IOS SDK : first advices for beginners

    - by VdesmedT
    I too often answer the same kind of questions regarding basic topics like memory management, UITableView, Interface Orientation, MVC, etc... I understand very well that everyone starting with that SDK is too exited about getting its hand on it but a few reading would save them hours of debugging and the frustration that come along with the feeling that "We miss something here". I'd like experience users to share the few small articles, white papers, docs, book chapters that helps other save their time and avoid frustration. My first vote would be for : IOS Memory Management Guide View Controller Programming Guide Table View Guide And as a General recommendation, read the Overview section that come along with every class documention in the reference library, they contains most of what you need to know to avoid big traps !

  • Using variables for colors in table cells

    - by Mark Robinson
    Using the variables extension, I want to change the background color of a cell in a table. So far I've done this: {{#vardefine:green|<span style="background:Green; color:White">text</span>}} The problem is that, when I add {{#var:green}} to the cell, only the text itself has a green background. Ideally, I want the whole cell to have a background color, like it does if I use this: | bgcolor="#ff00ff" | test or this | style="background:silver" |silver in the cell. Does anyone know how to solve this?

  • How can I draw a hollow rectangle using CreatePen?

    - by LarsTech
    Since using the DrawArc function in GDI+ isn't very accurate when drawing a small rounded rectangle, I am using RoundRect instead. Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs) Dim hDC As IntPtr = e.Graphics.GetHdc Dim rc As New Rectangle(10, 10, 64, 24) Dim hPen As IntPtr = Win32.CreatePen(Win32.PenStyle.PS_SOLID, 0, _ ColorTranslator.ToWin32(Color.Green)) Dim hOldPen As IntPtr = Win32.SelectObject(hDC, hPen) Call Win32.RoundRect(hDC, rc.Left, rc.Top, rc.Right, rc.Bottom, 10, 10) Win32.SelectObject(hDC, hOldPen) Win32.DeleteObject(hPen) e.Graphics.ReleaseHdc(hDC) MyBase.OnPaint(e) End Sub This will draw a nice rounded rectangle, but it will also fill it with a white brush, erasing what I don't want to have erased. How can I draw this without erasing the inside of the rectangle?

  • Sql Server XML-type column duplicate entry detection

    - by aaaa bbbb
    In Sql Server I am using an XML type column to store a message. I do not want to store duplicate messages. I only will have a few messages per user. I am currently querying the table for these messages, converting the XML to string in my C# code. I then compare the strings with what I am about to insert. Unfortunately, Sql Server pretty-prints the data in the XML typed fields. What you store into the database is not necessarily exactly the same string as what you get back out later. It is functionally equivalent, but may have white space removed, etc. Is there an efficient way to compare an XML string that I am considering inserting with those that are already in the database? As an aside, if I detect a duplicate I need to delete the older message then insert the replacement.

  • UITextField placeholder looks strange when UITableViewCellSelectionStyleGray

    - by mongeta
    Hello, I've set the background color of my UITableViewCells to Gray. But if there's a UITextField in the cell, the placeholder doesn't change their color to white/black and it's almost impossible to read it, and look stranges. The UILabel from the cell changes their color when it's selected or not, but the placeholder remains always the same. There's a simple solution ? I don't want to add some UILabel and use it as a placeholder, etc. etc. Thanks, r.

  • Adding on touch event to images inside gridview

    - by Steve
    I have a gridview where each item has a image and a textview (an app), i added the onItemClick to the gridview in order to launch the app, i also removed the orange selection and made selector in xml so when pressed the text would change to grey and on release it would return to white. My problem is that i need the image to apply an alpha value when pressed and restore the previous alpha on release i tested a lot of ways and none did worked correctly. I came close with the updated answer from the autor of the question: How to set alpha value for drawable in a StateListDrawable?, but some how the state pressed never gets called, i don´t know if this is because i am using the onitemClick to launch the app or not. Also i since i can´t define the alpha on imageview xml i don´t know what else to do Any help will be appreciated

  • C# GDI - How to check if a Pixel is opaque or not?

    - by rkawano
    I am using a method to get a pixel of the image to check if this point is transparent or not. I am using GetPixel that returns a System.Drawing.Color with a 32bit color info. This struct have the "A" property where I can get the alpha value of pixel, according to this MSDN topic. Code: using (Bitmap bmp = new Bitmap(path)) { Color pixel = bmp.GetPixel(0, 0); if (pixel.A == 0) // This is a fully transparent pixel else // This is not a fully transparent pixel } When I use this method with a fully transparent PNG images it returns 0. When I run with a white semi-transparent images, it will give me other values starting on 1 and up to 86, where 86 are given for images with a 100% alfa (full opaque). But with opaque JPEG images, the "A" property are giving me all sort of values like 56, 71, 86, 129, and others, depending on image. But these pixels are fully opaques! How are the correct way to check if a pixel is opaque or not?

  • efficient video format/codec for sparse & binary blob tracking

    - by user391339
    I am working on a blob tracking project and have many high-definition videos that I would like to reduce in size for storage and downstream tracking/shape-analysis. I want to use a lossless method that takes advantage of the black and white nature of the video as well as the fact that not much is moving between individual frames. The videos are quite sparse, with 5 to 10 b&w blobs per frame occupying <30% of the space in total, with each blob moving <5-10% of the field of view between frames and not changing shape too much between 2-3 frames. I will work in Python, Matlab, or LabView for this project, and could use a batch utility if available. It may be worthwhile to export the files as compressed image stacks if a proper video format can't be found. What are the pros and cons of this? A video codec uses correlations between neighboring frames, so it should be more efficient, but not if the wrong one is chosen or if it is improperly configured.

  • jQuery $.post & $.append & IE6

    - by Jim
    I'm having a weird problem with jQuery and IE6. Script works on IE7+ and with all other browsers I have tried it. I can't post the full script, but what it does is this: $.post("file.php",{'foo':'bar'},function(data){ $('#target').append(data) }) When I run the code in IE6, #target just shows ? and a white char with a hole in the middle. I have no idea what this second char is. My initial thought was that this was some sort of content-type problem because the file.php just echoes answer without any header information. I added Content-type: text/html with header() but didn't help. Any suggestions?

  • Using CSS to positon text after an image

    - by Charles L
    I've trying to do something that I'm sure is simple, but I can't do it. All I want to do is have an image and then some text after that image, and be able to control accurately the amount of space between the image and the text. Here's my code: http://pastebin.com/fx17XUaR I couldn't work out how to paste it in here directly. In my style sheet, wrap has these attributes: .wrap { //text-align: left; width: 1100px; height: 870px; background-color: white; color: black; padding: 10px; margin: auto; I want my text to look like this directly below the image: Username Age Location Currently, I just add loads of break tags to control where I have the text, but that's messy and there must be a better way. Thanks in advance for any help.

  • Searching for simple variable names like 'c' or 'x' in Emacs.

    - by wpeters
    I often wish to search for variables that are simply called 'c' or 'count'. For example int c, count; Unfortunately when I use an incremental search for 'c' or 'count' I get a lot of unnecessary hits like the 'c' in 'choice', or the 'count' in 'wordcount' which do not interest me. I know Emacs can do i-searches with regular expressions but I don't know the correct regular expression needed to match just 'c' and 'count'. These words are often surrounded by any number of white spaces. Anyone know the regex I can use to narrow my search?

  • Html how to make a part on iframe, unvisible and unclickable externally? (my idea)

    - by ozan
    I have a page (A) including a BUTTON with a function close_window() , however when I embed A to my main page (B) using iframe, the close_window() can't work as expected since there is no more window anymore, and I am not able to remove the button from the iframe since A is on another domain (Security issues prevents). What I want to do is make this button label invisible. And the only way I think is to put a white image just to the place where that button exists on my iframe, externally. is Smthing like that possible? I want the image to be on the top of iframe? Or do you have any other idea ? Thanks for helps.

  • WPF Labels look fine in XP, but are cut off at the bottom in Vista and Windows 7.

    - by juharr
    The following xaml looks fine in XP, but the bottom of the text gets cut off in Vista and Windows 7. <Grid> <Border Height="86" Margin="10,54,10,0" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="1"/> <Label Height="22" Width="100" Margin="15,43,0,0" VerticalAlignment="Top" HorizontalAlignment="Left" Background="White">Text Over Border</Label> </Grid> I realize that I could just increase the Height of the label, but I'm guessing I'll have problems with systems that have different resolution settings, or large text settings. Is there a better way to lay this out?

  • Converting a Matrix to a grid of colors

    - by Zach
    I'm currently making a console application in C# (will be going to a Windows Form application in the future. Sooner if needed). My current objective is to have a matrix (current size 52x42) be exported as an image (bitmap, jpeg, png, I'm flexible) where each value in the matrix (0, 1, 2, 3) is portrayed as a white, black, blue, or red square of size 20px x 20px with a grid 1px wide seperating each 'cell'. Can this even be done in a console application, and if so how? If not, what would I need to get it working in a Windows Form application?

  • Changing type of object in a conditional

    - by David Doria
    I'm having a bit of trouble with dynamic_casting. I need to determine at runtime the type of an object. Here is a demo: include include class PersonClass { public: std::string Name; virtual void test(){}; //it is annoying that this has to be here... }; class LawyerClass : public PersonClass { public: void GoToCourt(){}; }; class DoctorClass : public PersonClass { public: void GoToSurgery(){}; }; int main(int argc, char *argv[]) { PersonClass* person = new PersonClass; if(true) { person = dynamic_cast(person); } else { person = dynamic_cast(person); } person-GoToCourt(); return 0; } I would like to do the above. The only legal way I found to do it is to define all of the objects before hand: PersonClass* person = new PersonClass; LawyerClass* lawyer; DoctorClass* doctor; if(true) { lawyer = dynamic_cast(person); } else { doctor = dynamic_cast(person); } if(true) { lawyer-GoToCourt(); } The main problem with this (besides having to define a bunch of objects that won't be use) is that I have to change the name of the 'person' variable. Is there a better way? (I am not allowed to change any of the classes (Person, Lawyer, or Doctor) because they are part of a library that people who will use my code have and won't want to change). Thanks, Dave

  • C++: How do I correctly register and unregister file type associations for our application (programa

    - by Mordachai
    Time was when you set file associations in: HEY_CLASSES_ROOT\<.ext However, that seems to be possible, but an incomplete solution anymore. There are additional associations throughout the registry. For example: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\KindMap HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Extensions And all of the above, but by HKEY_USERS\ And Microsoft added their Set Default Associations control panel applet, which controls... what? I'm looking for a white paper, or discussions on: "How is a modern, Windows XP-Windows 7 compatible application written in C/C++ supposed to register and manipulate its file associations without interfering with Explorer, User-Settings, or the Default Associations cpl"

  • Non-deprecated replacement for NSCalibratedBlackColorSpace?

    - by uliwitness
    I'm implementing my own NSBitmapImageRep (to draw PBM image files). To draw them, I'm using NSDrawBitmap() and passing it the NSCalibratedBlackColorSpace (as the bits are 1 for black, 0 for white). Trouble is, I get the following warning: warning: 'NSCalibratedBlackColorSpace' is deprecated However, I couldn't find a good replacement for it. NSCalibratedWhiteColorSpace gives me an inverted image, and there seems to be no way to get NSDrawBitmap() to use a CGColorSpaceRef or NSColorSpace that I could create as a custom equivalent to NSCalibratedBlackColorSpace. I've found a (hacky) way to shut up the warning (so I can still build warning-free until a replacement becomes available) by just passing @"NSCalibratedBlackColorSpace" instead of the symbolic constant, but I'd rather apply a correct fix. Anybody have an idea?
