• ReportViewer Cell Formatting

  - by firedrawndagger

  I need to change the color of a cell in ReportViewer based on its value. 1) I got the first part down - I'm comparing the difference between two numbers like so: =IIf(Fields!variance.Value > 0) 2) Now how do I actually change the visual formatting of the cell? A web standards way would be to add a class - since then you can format the class to whatever you like, e.g. changing borders, typography, bacgkround color etc. Since ReportViewer sucks and doesn't have that functionality what should I use instead? Any hacks I could use?

• Building a webserver, client doesn't acknowledge HTTP 200 OK frame.

  - by Evert

  Hi there, I'm building my own webserver based on a tutorial. I have found a simple way to initiate a TCP connection and send one segment of http data (the webserver will run on a microcontroller, so it will be very small) Anyway, the following is the sequence I need to go through: receive SYN send SYN,ACK receive ACK (the connection is now established) receive ACK with HTTP GET command send ACK send FIN,ACK with HTTP data (e.g 200 OK) receive FIN,ACK <- I don't recieve this packet! send ACK Everything works fine until I send my acknowledgement and HTTP 200 OK message. The client won't send an acknowledgement to those two packages and thus no webpage is being displayed. I've added a pcap file of the sequence how I recorded it with wireshark. Pcap file: http://cl.ly/5f5 (now it's the right data) All sequence and acknowledgement numbers are correct, checksum are ok. Flags are also right. I have no idea what is going wrong.

• Lua Programming for PSP: Sending a string, then spliting that string

  - by Trey Andrews

  How do I send a string between 2 PSPs? Here is a test script: Script A Adhoc.init() Adhoc.connect() data1 = "Trey777" data2 = "This is a test!!..."

• .net c# text box date with mask - setup

  - by flavour404

  I have a c# .net project and want an input text box for a date value. I want it to display a default value of mm/dd/yyyy and then allow users to enter valid dates. I have tried using a masked text box but it doesn't like having the above format. If i try and use //__ looks naff and so does 00/00/0000 and of course if you put in '0' like 03/11/2009 you get 3/11/29 because the 0's are deleted as part of the mask - so what is the best way to set up an input box like this, effectively with a mask, only allowing numbers, and validation (though at this point I am not so worried about that). This seems so simple and isn't. Thanks, R.

• Subversion has --record-only for merges, how do I do the same in Git ?

  - by Paul Hammant

  I have a repo where 'master' is going in a certain direction, and a second branch 'foo' is going to be divergent for a couple of commits, then track all subsequent changes to 'master' after that. This is all by choice of course. In Subversion you could do a --record-only merge to mark things as "merge has happened" even though no actual changes were committed. i.e. this change the merge-tracking numbers in properties attached to directories in the target branch. I have had a play with.. git merge --no-commit master .. as something I may be able to tinker with before I do the commit, but it is making a hell of a mess of the target branch for part of the change in question (rename followed by delete). There must be an easier way.. ? Paul

• Using jQuery to rapidly scroll through a countdown

  - by CaptainAwesomePants

  I have a webpage that displays the number 0, and when the user presses "start", the number should rapidly increasing until it reaches a target number (maybe 10,000 or so) a few seconds later. I'd like the numbers to scroll by as if they're on a slot machine wheel. I've managed to mostly hack something together using the ScrollTo plugin, but it's slow and choppy. It always stops briefly at certain divs along the way. Perhaps I'm using it wrong. Is there a better way to accomplish such an effect?

• What is the purpose of Java's unary plus operator?

  - by Syntactic

  Java's unary plus operator appears to have come over from C, via C++. As near as I can tell, it has the following effects: promotes its operand to int, if it's not already an int or wider unboxes its operand, if it's a wrapper object complicates slightly the parsing of evil expressions containing large numbers of consecutive plus signs It seems to me that there are better (or, at least, clearer) ways to do all of these things. In this SO question, concerning the counterpart operator in C#, someone said that "It's there to be overloaded if you feel the need." But in Java, one cannot overload any operator. So does this operator exist in Java just because it existed in C++?

• Automatically determining the size of a UITableViewCell

  - by hanno

  I am trying to determine the size of a UITableCellView. The reason being that I am using one class for different orientations and devices. The cell contains one subview that is supposed to fill the entire cell. Right know I'm doing this in the UITableViewCell's init method: if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad){ //iPad subv = [[OrbitView alloc] initWithFrame:CGRectMake(52, 5, 660, 420) ]; }else{ //iPhone subv = [[OrbitView alloc] initWithFrame:CGRectMake(15, 5, 290, 200) ]; } Clearly, there must be a better way of doing this, without the magic numbers. How/Where should I set the frame of the subview in the UITableViewCell so that it fills the entire UITableViewCell?

• How to avoid piracy in iPhone apps by server side validation?

  - by prathumca

  As par my app requirement, there is a couple of scenarios that I need to handle. Scenario 1: To avoid piracy, I want to include some piece of code, whose job is sending both IMEI and Serial number of IPhone. Scenario 2: At server side, I've a database, which has a list of both IMEI and Serial No info. Here I wanna validate both IMEI and Serial numbers. If both are not matched then I can make sure that the app is pirated. Idea seems good. But I don't know how to handle these two scenarios in my app. Any help is greatly appreciated.

• Stack trace for C++ using gcc

  - by dimba

  We use stack traces in proprietary assert like macro to catch developer mistakes - when error is caught, stack trace is printed. I find gcc's pair backtrace()/backtrace_symbols() methods insufficient: Names are mangled No line information 1st problem can be resolved by abi::__cxa_demangle. However 2nd problem s more tough. I found replacement for backtrace_symbols(). This is better than gcc's backtrace_symbols(), since it can retrieve line numbers (if compiled with -g) and you don't need to compile with -rdynamic. Hoverer the code is GNU licenced, so IMHO I can't use it in commercial code. Any proposals?

• Parallel Assignment operator in Ruby

  - by Bragaadeesh

  Hi, I was going through an example from Programming in Ruby book. This is that example def fib_up_to(max) i1, i2 = 1, 1 # parallel assignment (i1 = 1 and i2 = 1) while i1 <= max yield i1 i1, i2 = i2, i1+i2 end end fib_up_to(100) {|f| print f, " " } The above program simply prints the fibonacci numbers upto 100. Thats fine. My question here is when i replace the parallel assignment with something like this, i1 = i2 i2 = i1+i2 I am not getting the desired output. My question here is, is it advisable to use parallel assignments? (I come from Java background and it feels really wierd to see this type of assignment) One more doubt is : Is parallel assignment an operator?? Thanks

• How Do I Pull Info from String

  - by Russ Bradberry

  I am trying to pull dynamics from a load that I run using bash. I have gotten to a point where I get the string I want, now from this I want to pull certain information that can vary. The string that gets returned is as follows: Records: 2910 Deleted: 0 Skipped: 0 Warnings: 0 Each of the number can and will vary in length, but the overall structure will remain the same. What I want to do is be able to get these numbers and load them into some bash variables ie: RECORDS=?? DELETED=?? SKIPPED=?? WARNING=?? In regex I would do it like this: Records: (\d*?) Deleted: (\d*?) Skipped (\d*?) Warnings (\d*?) and use the 4 groups in my variables.

• Centralizing a floating element :(

  - by 2x2p1p

  Hi guys :| My "div" element have a relative width, it isn't absolute so I can't use exact numbers to centralize. A nice solution is to use "display: inline-block": body { text-align: center; } #myDiv { border: 1px solid black; display: inline-block; padding: 50px; } But this element NEEDS to float, I tried this: #myDiv { border: 1px solid black; display: inline-block; float: left; padding: 50px; } And this: #myDiv { border: 1px solid black; display: inline-block; padding: 50px; position: absolute; } Without any success, can somebody help me ? Thanks

• MySQL storing negative and positive decimals

  - by Shishant

  Hello, I want to be able to store -11.99 and +11.99 kind of values in mysql db I am thinking of decimals instead of varchar. But reading mysql site I found out that its incompatible with older versions of mysql As a result of the change from string to numeric format for DECIMAL storage, DECIMAL columns no longer store a leading + or - character or leading 0 digits. Before MySQL 5.0.3, if you inserted +0003.1 into a DECIMAL(5,1) column, it was stored as +0003.1. As of MySQL 5.0.3, it is stored as 3.1. For negative numbers, a literal - character is no longer stored. Applications that rely on the older behavior must be modified to account for this change. So what should be the data type, If I have to give up varchar and make it compatible with older versions too?

• Php is stripping one letter "g" from my rtrim function but not other chars

  - by Chase

  I'm trying to trim some youtube URLs that I am reading in from a playlist. The first 3 work fine and all their URLs either end in caps or numbers but this one that ends in a lower case g is getting trimmed one character shorter than the rest. for ($z=0; $z <= 3; $z++) { $ythref2 = rtrim($tubeArray["feed"]["entry"][$z]["link"][0]["href"], '&feature=youtube_gdata'); The URL is http://www.youtube.com/watch?v=CuE88oVCVjg&feature=youtube_gdata .. and it should get trimmed down to .. http://www.youtube.com/watch?v=CuE88oVCVjg but instead it is coming out as http://www.youtube.com/watch?v=CuE88oVCVj. I think it may be the ampersand symbol but I am not sure.

• How to set Chrome's user script version number.

  - by Atli

  Hey. I've been wondering how I might set the version number displayed for user-scripts in Chrome's extension tab So far the obvious methods have failed: // ==UserScript== // @version 1.1.5 // @uso:version 1.1.5 // ==/UserScript== I know Greasemonkey for Firefox doesn't use a version value, but since Chrome actually displays a version number, I thought it might. Perhaps this is a feature that has not been implemented? Or maybe it was never intended to be there, but it is there because extensions have version numbers, and user-scripts are currently installed as extensions? (I'm using the Linux beta, version: 4.0.249.43, by the way) Thanks. Edit: Seems this is listed as an unconfirmed bug in the Chromium bug database (Issue 30760)

• Why does DataInputStream not support integers?

  - by Jason

  I need to read in a list of numbers from a file, none of which are larger than 32767. Originally I was going to use the Scanner class to pull in the data, then I read about DataInputStream. This would work well for me, except that according to the API, it supports all primitive variables EXCEPT ints! Listed are longs, shorts, bytes, chars, booleans, ect, but no ints. I have no need for double precision from the incoming data. Is this a deliberate or unintentional oversight?

• How do I get Git's latest stable release version number?

  - by MattDiPasquale

  I'm writing a git-install.sh script: http://gist.github.com/419201 To get Git's latest stable release version number, I do: LSR_NUM=$(curl -silent http://git-scm.com/ | sed -n '/id="ver"/ s/.*v\([0-9].*\)<.*/\1/p') 2 Questions: Refactor my code: Is there a better way programmatically to do this? This works now, but it's brittle: if the web page at http://git-scm.com/ changes, the line above may stop working. PHP has a reliable URL for getting the latest release version: http://stackoverflow.com/questions/288206/is-there-a-site-which-simply-outputs-the-latest-stable-version-numbers-of-php-and Is there something like this for Git?

• AJAX response inside jqplot not working

  - by JuanGesino

  I'm trying to render data from an AJAX response as a bar chart with jqplot. To render this bar chart I use two variables: s1 which contains the numbers ex: s1 = [22,67,32,89] ticks which contains the name corresponding to a number inside s1 ex: ticks = ["Jack", "Mary", "Paul", "John"] So my AJAX returns two variables, data1 and data2. When I console.log(data1) I get 22,67,32,89 When I console.log(data2) I get "Jack", "Mary", "Paul", "John" I then add the square brackets and change variable: s1 = [data1] ticks = [data2] When I console.log(s1) I get ["22,67,32,89"] When I console.log(ticks) I get "Jack", "Mary", "Paul", "John" And the graph does not render, this is my code: s1 = [data]; ticks = [data]; plot4 = $.jqplot('chartdiv4', [s1], { animate: !$.jqplot.use_excanvas, series:[{color:'#5FAB78'}], seriesDefaults:{ renderer:$.jqplot.BarRenderer, pointLabels: { show: true } }, axes: { xaxis: { renderer: $.jqplot.CategoryAxisRenderer, ticks: ticks }, yaxis:{min:0, max:100, label:'%',labelRenderer: $.jqplot.CanvasAxisLabelRenderer} }, highlighter: { show: false } }); });

• Unix: millionth number in the serie 2 3 4 6 9 13 19 28 42 63 ... ?

  - by HH

  It takes about minute to achieve 3000 in my comp but I need to know the millionth number in the serie. The definition is recursive so I cannot see any shortcuts except to calculate everything before the millionth number. How can you fast calculate millionth number in the serie? Serie Def n_{i+1} = \floor{ 3/2 * n_{i} } and n_{0}=2. Interestingly, only one site list the serie according to Goolge: this one. Too slow Bash code #!/bin/bash function serie { n=$( echo "3/2*$n" | bc -l | tr '\n' ' ' | sed -e 's@\\@@g' -e 's@ @@g' ); # bc gives \ at very large numbers, sed-tr for it n=$( echo $n/1 | bc ) #DUMMY FLOOR func } n=2 nth=1 while [ true ]; #$nth -lt 500 ]; do serie $n # n gets new value in the function throught global value echo $nth $n nth=$( echo $nth + 1 | bc ) #n++ done

• Source code annotation tool

  - by RoToRa

  I'm looking for a tool with which I can annotate source code. I have some 3rd party source code (JavaScript) I need to understand and I don't want to change it (add inline comments) so that line numbers can stay intact (for communication with others), I can avoid accidentally changing something and my annotations stand out compared to the authors comments. Normally I would print the whole thing out an scribble on it, but the code is too long for that and I need to share it per email. I would be great if one could do some like that including being able to create "links" between so places in the code, possibly even visually with a lines or arrows.

• Chaning coding style due to Android GC performance, how far is too far?

  - by Benju

  I keep hearing that Android applications should try to limit the number of objects created in order to reduce the workload on the garbage collector. It makes sense that you may not want to created massive numbers of objects to track on a limited memory footprint, for example on a traditional server application created 100,000 objects within a few seconds would not be unheard of. The problem is how far should I take this? I've seen tons of examples of Android applications relying on static state in order supposedly "speed things up". Does increasing the number of instances that need to be garbage collected from dozens to hundreds really make that big of a difference? I can imagine changing my coding style to now created hundreds of thousands of objects like you might have on a full-blown Java-EE server but relying on a bunch of static state to (supposedly) reduce the number of objects to be garbage collected seems odd. How much is it really necessary to change your coding style in order to create performance Android apps?

• A specific string format with a number and character together represeting a certain item

  - by sil3nt

  Hello there, I have a string which looks like this "a 3e,6s,1d,3g,22r,7c 3g,5r,9c 19.3", how do I go through it and extract the integers and assign them to its corresponding letter variable?. (i have integer variables d,r,e,g,s and c). The first letter in the string represents a function, "3e,6s,1d,3g,22r,7c" and "3g,5r,9c" are two separate containers . And the last decimal value represents a number which needs to be broken down into those variable numbers. my problem is extracting those integers with the letters after it and assigning them into there corresponding letter. and any number with a negative sign or a space in between the number and the letter is invalid. How on earth do i do this?

• How to file split at a line number

  I want to split a 400k line long log file from a particular line number. For this question, lets make this an arbitrary number 300k. Is there a linux function that allows me to do this? I know split lets me split the file in equal parts either by size or line numbers but that's not what I want. I want to the first 300k in one file and the last 100k in the second file. Any help would be appreciated. Thanks!
