• Build turns partially transparent image pixels black

  - by Sean O'Hollaren

  I'm very new to C# and I've run into a problem and haven't been able to solve it. I have a row of buttons that have .png images assigned to them. The images are in .png format to allow transparency, and smoothing the edges in GIMP leaves some semi-transparent pixels. I've set the Image List Toolbar (imglToolbar)'s properties to recognize "Transparent" as the designated color to show up as transparent. I'm working in Visual Studio 2005. The strange thing is that everything looks great when I'm viewing the Visual C# form preview window. The icons look exactly as they should. However, once I actually build the project, the buttons treat every semi-transparent pixel near the edge of the image as if it's black. It seems like it can't handle one that's both transparent and has color. Image of it via the Visual C# form editor: Image of what it looks like when built: Any ideas as to why this is happening?

• String Encoding doesn't ouput all characters

  - by AndroidXTr3meN

  My client uses InputStreamReader/BufferedReader to fetch text from the Internet. However when I save the Text to a *.txt the text shows extra weird special symbols like 'Â'. I've tried Convert the String to ASCII but that mess upp å,ä,ö,Ø which I use. I've tried food = food.replace("Â", ""); and IndexOf(); But string won't find it. But it's there in HEX Editor. So summary: When I use text.setText(Android), the output looks fine with NO weird symbols, but when I save the text to *.txt I get about 4 of 'Â'. I do not want ASCII because I use other Non-ASCII character. The 'Â' is displayed as a Whitespace on my Android and in notepad. Thanks! Have A great Weekend! EDIT* found:   in Wordpad

• How to make CSS/HTML prototyping faster for engineers without strong CSS skills?

  - by rdeshpande

  I've been developing Ruby on Rails applications for some time, and have often found help to develop generate the templates of HTML with accompanying CSS. However, I'd like to make an attempt at doing this myself. Initial experiments leave me feeling like my process is really slow. I'm writing all my Rails code in VIM, which, with accompanying aliases to run the test suite, is pretty fast for me. However, the back-and-forth between browser/VIM to see new changes seems cumbersome - I'm guessing finding an editor with an embedded browser that constantly sees new changes is ideal for this (any suggestions?) So far I've experimented with Blueprint, which at the onset seems like it will save me a ton of time. However, what other tools have helped you do the PSD-HTML/CSS conversion as fast as you can?

• Convert a image to a monochrome byte array

  - by Scott Chamberlain

  I am writing a library to interface C# with the EPL2 printer language. One feature I would like to try to implement is printing images, the specification doc says p1 = Width of graphic Width of graphic in bytes. Eight (8) dots = one (1) byte of data. p2 = Length of graphic Length of graphic in dots (or print lines) Data = Raw binary data without graphic file formatting. Data must be in bytes. Multiply the width in bytes (p1) by the number of print lines (p2) for the total amount of graphic data. The printer automatically calculates the exact size of the data block based upon this formula. I plan on my source image being a 1 bit per pixel bmp file, already scaled to size. I just don't know how to get it from that format in to a byte[] for me to send off to the printer. I tried ImageConverter.ConvertTo(Object, Type) it succeeds but the array it outputs is not the correct size and the documentation is very lacking on how the output is formatted. My current test code. Bitmap i = (Bitmap)Bitmap.FromFile("test.bmp"); ImageConverter ic = new ImageConverter(); byte[] b = (byte[])ic.ConvertTo(i, typeof(byte[])); Any help is greatly appreciated even if it is in a totally different direction.

• ajax Post data missing with tinyMCE on Firefox

  - by Freeman

  I have a problem with my form when I try to submit with ajax. I am using Malsup Form plugin for Jquery but also using tinyMCE editor. When I submit the form and check the $_POST array, there is no data from the textarea. I have tried to use the triggerSave() function but to no avail. Everything is working well in IE. // These options are common and will be used for many form submissions var options = { target: '#notice', // target element(s) to be updated with server response dataType:'html', resetForm:true, beforeSubmit: function(){tinyMCE.triggerSave(false,true); }, success:function(msg){ $('#notice').html( msg) refresh(3) } }; //prepare form $('#savetext').ajaxForm(options);

• Version resource in DLL not visible with right-click

  - by abunetta

  I'm trying to do something which is very easy to do in the regular MSVC, but not supported easily in VC++ Express. There is no resource editor in VC++ Express. So I added a file named version.rc into my DLL project. The file has the below content, which is compiled by the resource compiler and added to the final DLL. This resource is viewable in the DLL using reshacker, though not when right-clicking the DLL in Windows Explorer. What is missing from my RC file to make it appear when right-clicking? VS_VERSION_INFO VERSIONINFO FILEVERSION 1,0,0,1 PRODUCTVERSION 1,0,0,1 FILEFLAGSMASK 0x17L #ifdef _DEBUG FILEFLAGS 0x1L #else FILEFLAGS 0x0L #endif FILEOS 0x4L FILETYPE 0x1L FILESUBTYPE 0x0L BEGIN BLOCK "StringFileInfo" BEGIN BLOCK "040904b0" BEGIN VALUE "FileDescription", "something Application" VALUE "FileVersion", "1, 0, 0, 1" VALUE "InternalName", "something" VALUE "LegalCopyright", "Copyright (C) 2008 Somebody" VALUE "OriginalFilename", "something.exe" VALUE "ProductName", "something Application" VALUE "ProductVersion", "1, 0, 0, 1" END END BLOCK "VarFileInfo" BEGIN VALUE "Translation", 0x409, 1200 END END

• Keeping Track of Dependant Third-party Library Releases

  - by Sonny

  I am building a web application that is dependent upon several third-party libraries. What is a good strategy for making sure that you're always using the most fully patched versions? A simple method would be to keep the versions written down and visit the websites at regular intervals, but I am looking for some way to get the information 'pushed' to me if possible. I figured that there might be others out there who have needed to do the same thing and have worked out a good solution. Here are a few libraries I am using: Zend Framework jQuery HTMLPurifier Markdownify InnovaStudio WYSIWYG Editor Fancybox MojoZoom

• Drawing rectangles on a grid in a web browser

  - by Dhruv

  I would like to create an online, simple WYSIWYG drawing editor allowing people to draw rectangular shapes. I'm thinking of a grid which the lines and points can snap on to, ensuring that the lines are strictly vertical or horizontal. I will be parsing the rectangular shapes to obtain some area calculations and compute certain things. How can I achieve the drawing ability? The new canvas tag is good but people have been telling me that IE does not support it. I found some Java applets but I have never programmed in Java before. Is there a way to do this using pure javascript or jquery? Does ASP.NET help at all? Thanks.

• 2D Histogram in R: Converting from Count to Frequency within a Column

  - by Jac

  Would appreciate help with generating a 2D histogram of frequencies, where frequencies are calculated within a column. My main issue: converting from counts to column based frequency. Here's my starting code: # expected packages library(ggplot2) library(plyr) # generate example data corresponding to expected data input x_data = sample(101:200,10000, replace = TRUE) y_data = sample(1:100,10000, replace = TRUE) my_set = data.frame(x_data,y_data) # define x and y interval cut points x_seq = seq(100,200,10) y_seq = seq(0,100,10) # label samples as belonging within x and y intervals my_set$x_interval = cut(my_set$x_data,x_seq) my_set$y_interval = cut(my_set$y_data,y_seq) # determine count for each x,y block xy_df = ddply(my_set, c("x_interval","y_interval"),"nrow") # still need to convert for use with dplyr # convert from count to frequency based on formula: freq = count/sum(count in given x interval) ################ TRYING TO FIGURE OUT ################# # plot results fig_count <- ggplot(xy_df, aes(x = x_interval, y = y_interval)) + geom_tile(aes(fill = nrow)) # count fig_freq <- ggplot(xy_df, aes(x = x_interval, y = y_interval)) + geom_tile(aes(fill = freq)) # frequency I would appreciate any help in how to calculate the frequency within a column. Thanks! jac EDIT: I think the solution will require the following steps 1) Calculate and store overall counts for each x-interval factor 2) Divide the individual bin count by its corresponding x-interval factor count to obtain frequency. Not sure how to carry this out though. .

• Show SVG files on Sharepoint 2007

  - by Nicolas Irisarri

  I'm building a WSS site which has to show SVG files stored on WSS. I'm trying to use <object> tag to show it and it doesn't show, however, if I use <embed> it works ok. Im'using IE8 and IE7 I've been reading and everyone tells IE prefers <Object> over <embed>, but in WSS it doesn't work this way. To display the file I'm using a web content editor webpart with this code: <object type="image/svg+xml" data="/samples/sample.svg" name="owMain" width="400" height="150"> </object> Any clue??

• SVN Export in Eclipse removes labels on tabs

  - by Sorcy

  I have a very strange effect when using subclipse with eclipse. Whenever I use Team-Export to export a file from the editor the export works fine, but the label of the tab of the file is removed. Effect can be seen here: http://www.daspferd.de/img/tabs.png Strangely enough it happens with php-files, css-files, html-files but NOT with javascript-files. So I'm assuming it's some kind of setting that I haven't found yet and not a bug in subclipse. Anyone know where I can shut down this behaviour?

• Prevent backspace button from navigating back in Sharepoint 2010 and IE

  - by Machinegon

  as a user requirement I have to disable the backspace button from navigating back in the history. I made the following piece of code //Bind back nutton to prevent escaping the page with backspace $j(document).unbind('keydown').bind('keydown', function (event) { var doPrevent = false; if (event.keyCode === 8) { if(event.target == document.body){ if(event.preventDefault()){ event.preventDefault(); } event.stopEvent(); event.returnValue = false; } } }); This is working perfectly in all the browsers except IE8/7. I cannot bind the input types as exceptions because the content editor in sharepoint allows to modify the text in div or paragraph elements etc. The solution is not working in IE8 because the event.target returns the element that is on mouseover when there's no controls that has the focus. All tips will be appreciated. Thanks!!

• What's the best way to set cursor/caret position?

  - by Daniel Bachhuber

  If I'm inserting content into a textarea that TinyMCE has co-opted, what's the best way to set the position of the cursor/caret? I'm using tinyMCE.execCommand("mceInsertRawHTML", false, content); to insert the content, and I'd like set the cursor position to the end of the content. Both document.selection and myField.selectionStart won't work for this, and I feel as though this is going to be supported by TinyMCE (through something I can't find on their forum) or it's going to be a really ugly hack. Later: It gets better; I just figured out that, when you load TinyMCE in WordPress, it loads the entire editor in an embedded iframe. Later (2): I can use document.getElementById('content_ifr').contentDocument.getSelection(); to get the selection as a string, but not a Selection Object that I can use getRangeAt(0) on. Making progress little by little.

• What is the code for a number sign in sharepoint?

  - by Robin

  I've created a link in Sharepoint using the Content Editor Web Part. My link uses html to open up an email with the fields to, cc, subject, and body filled out. However, in the cc section I need a number sign (#) for a mailbox. When I use the html code & #35;(minus the space) my entire code crumbles. Everything starting at the "&" disappears. However, just for kicks I tried & pound;(minus the space) and the code works for a european pound sign. Not sure what else to try. Any suggestions?

• Function Returning Negative Value

  - by Geowil

  I still have not run it through enough tests however for some reason, using certain non-negative values, this function will sometimes pass back a negative value. I have done a lot of manual testing in calculator with different values but I have yet to have it display this same behavior. I was wondering if someone would take a look at see if I am missing something. float calcPop(int popRand1, int popRand2, int popRand3, float pERand, float pSRand) { return ((((((23000 * popRand1) * popRand2) * pERand) * pSRand) * popRand3) / 8); } The variables are all contain randomly generated values: popRand1: between 1 and 30 popRand2: between 10 and 30 popRand3: between 50 and 100 pSRand: between 1 and 1000 pERand: between 1.0f and 5500.0f which is then multiplied by 0.001f before being passed to the function above Edit: Alright so after following the execution a bit more closely it is not the fault of this function directly. It produces an infinitely positive float which then flips negative when I use this code later on: pPMax = (int)pPStore; pPStore is a float that holds popCalc's return. So the question now is, how do I stop the formula from doing this? Testing even with very high values in Calculator has never displayed this behavior. Is there something in how the compiler processes the order of operations that is causing this or are my values simply just going too high? If the later I could just increase the division to 16 I think.

• Why can't I have static public fields in my managed beans?

  - by AlanObject

  I just started using the Netbeans 7.1 beta and it is calling out errors of a type which I have never seen before. Specifically: A managed bean with a public field should not declare any scope other than @Dependent. The fields it is complaining about are public static final. I can understand the restriction on non-static fields, but I can't think of a good reason this would not be allowed for a static field. Unfortunately I use a lot of them since I don't like having constants in my code. I note that even though I get the red dot in the margin in the editor, the maven-driven build still works and GlassFish still runs my application the way I would expect. So what is my denoument on this issue? Am I going to have to move my static fields elsewhere or is there another way of handling this?

  I have a HTML form that is sometimes submitted with accented characters: à, è, ì, ò, ù I have a PHP script that exports these form submissions into CSV format, when I look at the CSV format in a text editor (vim or notepad for example) the characters look fine, but when opened with Open Office or Word, I get some funky results: ????? I am also passing these submission to salesforce and am getting an error: "The entity "Atilde" was referenced, but not declared." What can I do to ensure portability of my CSV file?

• Collaborative kernel development

  - by Raffo

  Hi, I have to develop a patch for the linux kernel (2.6) for an university course I'm attending. I have to develop this patch with a friend of mine and we need to edit the same files on our computers (2-3 PCs). So, we want to use something like a collaborative editor and/or a version control system. The problem is that we never used something like that and that we cannot release our software as open source till we take the exam. Obviously, we're using linux. I'm here to ask you suggestions in order to manage our work in the best way. Thank you

• Best ways to reuse Java methods

  - by carillonator

  I'm learning Java and OOP, and have been doing the problems at Project Euler for practice (awesome site btw). I find myself doing many of the same things over and over, like: checking if an integer is prime/generating primes generating the Fibonacci series checking if a number is a palindrome What is the best way to store and call these methods? Should I write a utility class and then import it? If so, do I import a .class file or the .java source? I'm working from a plain text editor and the Mac terminal. Thanks!

• Bash: any command to replace strings in text files?

  - by mikez302

  I have a hierarchy of directories containing many text files. I would like to search for a particular text string every time it comes up in one of the files, and replace it with another string. For example, I may want to replace every occurrence of the string "Coke" with "Pepsi". Does anyone know how to do this? I am wondering if there is some sort of Bash command that can do this without having to load all these files in an editor, or come up with a more complex script to do it. I found this page explaining a trick using sed, but it doesn't seem to work in files in subdirectories.

• Listview icons show up blurry (C#)

  - by Balk

  I'm attempting to display a "LargeIcon" view in a listview control, however the images I specify are blurry. This is what I have so far: The .png files are 48x48 and that's what I have it set to display at in the ImageList properties. There's one thing that I've noticed (which is probably the cause) but I don't know how to change it. Inside the "Images Collection Editor" where you choose what images you want for the ImageList control, it looks like it's setting the wrong size for each image. As you can see the "PhysicalDimension" and the "Size" is set to 16x16 and not abled to be manipulated. Does anyone have any ideas? Many thanks!
