  • VB.net Need Text Box to Only Accept Numbers

    - by Rico Jackson
    I'm fairly new to VB.net (self taught) and was just wondering if someone out there could help me out with some code. I'm not trying to do anything to invovled, just have a textbox that takes numeric value from 1 to 10. I don't want it to take a string or any number above 10. If some types a word or character an error message will appear, telling them to enter a valid number. This is what I have, obviously it's not great as I am having problems. Thanks again to anyone who can help. If TxtBox.Text > 10 Then MessageBox.Show("Please Enter a Number from 1 to 10") TxtBox.Focus() ElseIf TxtBox.Text < 10 Then MessageBox.Show("Thank You, your rating was " & TxtBox.Text) Total = Total + 1 ElseIf IsNumeric(TxtBox.Text) Then MessageBox.Show("Thank you, your rating was " & ValueTxtBox.Text) End If ValueTxtBox.Clear() ValueTxtBox.Focus()

    - by Sami
    Hi, i need a little help i have a method which gets value such as 50, it then assigns that value to trackDuration, so NSNumber *trackDuration = 50, i want the method to every second minus 1 from the value of trackDuration and update a label, the label being called duration. Here's what i have so far; - (void) countDown { iTunesApplication *iTunes = [SBApplication applicationWithBundleIdentifier:@"com.apple.iTunes"]; NSNumber *trackDuration = [NSNumber numberWithDouble:[[iTunes currentTrack] duration]]; while (trackDuration > 0) { trackDuration - 1; int inputSeconds = [trackDuration intValue]; int hours = inputSeconds / 3600; int minutes = ( inputSeconds - hours * 3600 ) / 60; int seconds = inputSeconds - hours * 3600 - minutes * 60; NSString *trackDurationString = [NSString stringWithFormat:@"%.2d:%.2d:%.2d", hours, minutes, seconds]; [duration setStringValue:trackDurationString]; sleep(1); }} Any help would be much appreciated, thanks in advanced, Sami.

  • creating a JQuery function

    - by Russell Parrott
    Sorry to bother you guys & girls again on Christmas eve, but I need help creating a reusable JQuery function. I have "badly crafted" this set of code that all works. But I would really like to put it as a function so I don't have to keep repeating everything for each form. I am not too sure about how all the if statements can be combined etc. that is why I wrote it as it is. Any help much appreciated - Oh I suppose it could also be some kind of plugin but that might be the next step if I can understand how the function works. $(':input:visible').live('blur',function(){ if($(this).attr('required')) { if($(this).val() == '' ) { $(this).css({'background-color':'#FFEEEE' }); $(this).parent('form').children('input[type=submit]').hide(); $(this).next('.errormsg').html('OOPs ... '+$(this).prev('label').html()+' is required'); $(this).focus(); $(this).attr('placeholder').hide(); } else { $(this).css({'background-color':'#FFF' , 'border-color':'#999999'}); $(this).next('.errormsg').empty(); $(this).parent('form').children('input[type=submit]').show(); } } return false; }); $(':input[max]').live('blur',function(){ if($(this).attr('max') < parseInt($(this).val()) ){ $(this).next('.errormsg').html( 'OOPs ... the maximum value is '+$(this).attr('max') ); $(this).parent('form').children('input[type=submit]').hide(); $(this).focus(); } else {} return false; }); $(':input[min]').live('blur',function(){ if($(this).attr('min') > parseInt($(this).val()) ){ $(this).next('.errormsg').html( 'OOPs ... the minimum value is '+$(this).attr('min') ); $(this).parent('form').children('input[type=submit]').hide(); $(this).focus(); } else {} return false; }); $(':input[maxlength]').live('keyup',function(){ if($(this).val()==''){ } else { $(this).next('.errormsg').html( $(this).attr('maxlength')- $(this).val().length +' chars remaining'); } return false; }); As said, help much appreciated with one small (I hope) thing, how can I break out of any function IF there are no error messages to actually submit the form?

  • Determining Connections between data in a single table

    - by user1689749
    Hi I'm a BA / programmer type doing data analysis on a legacy system. I've been teaching myself SQL to help, but I've appeared to hit upon a problem bigger than my abilities. I have two tables (generalized for simplicity): Table Objects Object_PK Table Components Component_PK Object_FK Component_Type There are 100+ distinct values in Component_Type_Code. Given that any object can have N number of Components, how can I see which Component_Type(s) appear with other Component_Type(s)? For example, the following query tells me what component_types appear with the component_type 'Component_type_1': select component_type_code, count(*) from components where object_fk in ( select object_fk from components where component_type_code = 'component_type_1' ) group by component_type_code I'd like to get a query to show me all connections My apologies for the formatting. Any help is appreciated. I've looked at cube and rollup, but didn't know how to apply to this situtation.

  • Google Web Optimizer -- How long until winning combination?

    - by Django Reinhardt
    I've had an A/B Test running in Google Web Optimizer for six weeks now, and there's still no end in sight. Google is still saying: "We have not gathered enough data yet to show any significant results. When we collect more data we should be able to show you a winning combination." Is there any way of telling how close Google is to making up its mind? (Does anyone know what algorithm does it use to decide if there's been any "high confidence winners"?) According to the Google help documentation: Sometimes we simply need more data to be able to reach a level of high confidence. A tested combination typically needs around 200 conversions for us to judge its performance with certainty. But all of our conversions have over 200 conversations at the moment: 230 / 4061 (Original) 223 / 3937 (Variation 1) 205 / 3984 (Variation 2) 205 / 4007 (Variation 3) How much longer is it going to have to run?? Thanks for any help.

  • Shell Script - comparing lines of text, deleting matches

    - by SirRatty
    Hi all, I've done some searching for this but cannot find what I'm after, specifically. I have two files: "a.txt", "b.txt". Each contains a list of email addresses, separated by newlines. For all lines in "a.txt", I need to check for a match anywhere in "b.txt". If so, the email address in "a.txt" needs to be removed. (Alternatively, a new file "c.txt" could be created with the output if that is easier.) I'm using Mac OS X, so am looking for a shell script that could help, or pointers to how I'd go about constructing the script. Thanks for any help.

  • DDE Server Windows:orcascr9.exe: Application Error

    - by Critical Skill
    Hello I've looked at the queries on SO that pertain to similar errors - but haven't found anything so far, to help with this particular problem I am having with an orcascript which I am running under Powerbuilder9.0. The orca script connects to an SCC service provider, does a full target refresh, and then is supposed to build the exe. It never gets to the last step though. The log is not very informative and simply says this at the point of failure: PBORCA_SccRefreshTarget. Full Rebuild Calling cm_rebuild_application(CM_REBUILD_FULL) While the script is at some way into this above step, it exits and throws up the DDE server error. Can someone help me figure this one out? I just barely know the basics of PB, and the intent of this exercise is to convert an IDE-based build that I inherited, into an orcascript build so that i can run the build unmonitored. Thanks in advance!

  • non-servlet JSP

    - by h2g2java
    I realise there are EL and near EL frameworks like StringTemplate, JUEL, Velocity, etc. However, I am not asking for list of alternatives to JSTL/EL. I came across a package more than a year ago, someone who wrote a util that emulates the functionality of JSP for non-servlet env, i.e., JSP composition which does not need a "servlet container" to function. I ignored it and now I think it would be helpful to me and I need help to recall what it is. My actual motivation is similar to what StringTemplate, JUEL, Velocity would offer to help me compose SQL blocks, HTML blocks but I am thinking that JSPs are precompiled into bytecode and JSPs are more run-time efficient since run-time parsing is done no more than once. So actually, recommendation for alternatives would be acceptable as long as the templates are precompiled into bytecode. But I still prefer the JSP emulator.

  • Retain Count Question: Some Guidance, Please

    - by yar
    [I'm sure this is not odd at all, but I need just a bit of help] I have two retain properties @property (nonatomic, retain) NSArray *listContent; @property (nonatomic, retain) NSArray *filteredListContent; and in the viewDidLoad method I set the second equal to the first (so now the retainCount is two, I think): self.filteredListContent = self.listContent; and then on every search I do this self.filteredListContent = [listContent filteredArrayUsingPredicate:predicate]; I thought I should do a release right above this assignment -- since the property should cause an extra retain, right? -- but that causes the program to explode the second time I run the search method. The retain counts (without the extra release) are 2 the first time I come into the search method, and 1 each subsequent time (which is what I expected, unfortunately). Some guidance would help, thanks! Is it correct to not release?

  • Faster forking of large processes on Linux ?

    - by timday
    What's the fastest, best way on modern Linux of achieving the same effect as a fork-execve combo from a large process ? My problem is that the process forking is ~500MByte big, and a simple benchmarking test achieves only about 50 forks/s from the process (c.f ~1600 forks/s from a minimally sized process) which is too slow for the intended application. Some googling turns up vfork as having being invented as the solution to this problem... but also warnings about not to use it. Modern Linux seems to have acquired related clone and posix_spawn calls; are these likely to help ? What's the modern replacement for vfork ? I'm using 64bit Debian Lenny on an i7 (the project could move to Squeeze if posix_spawn would help).

  • How to get started with testing(jMock)

    - by London
    Hello, I'm trying to learn how to write tests. I'm also learning Java, I was told I should learn/use/practice jMock, I've found some articles online that help to certain extend like : http://www.theserverside.com/news/1365050/Using-JMock-in-Test-Driven-Development http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock And most articles I found was about test driven development, write tests first then write code to make the test pass. I'm not looking for that at the moment, I'm trying to write tests for already existing code with jMock. The official documentation is vague to say the least and just too hard for me. Does anybody have better way to learn this. Good books/links/tutorials would help me a lot. thank you EDIT - more concrete question : http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock - from this article Tried this to mock this simple class : import java.util.Map; public class Cache { private Map<Integer, String> underlyingStorage; public Cache(Map<Integer, String> underlyingStorage) { this.underlyingStorage = underlyingStorage; } public String get(int key) { return underlyingStorage.get(key); } public void add(int key, String value) { underlyingStorage.put(key, value); } public void remove(int key) { underlyingStorage.remove(key); } public int size() { return underlyingStorage.size(); } public void clear() { underlyingStorage.clear(); } } Here is how I tried to create a test/mock : public class CacheTest extends TestCase { private Mockery context; private Map mockMap; private Cache cache; @Override @Before public void setUp() { context = new Mockery() { { setImposteriser(ClassImposteriser.INSTANCE); } }; mockMap = context.mock(Map.class); cache = new Cache(mockMap); } public void testCache() { context.checking(new Expectations() {{ atLeast(1).of(mockMap).size(); will(returnValue(int.class)); }}); } } It passes the test and basically does nothing, what I wanted is to create a map and check its size, and you know work some variations try to get a grip on this. Understand better trough examples, what else could I test here or any other exercises would help me a lot. tnx

  • How to manage end user documentation for a project under continuous integration?

    - by mcdon
    I have a project under continuous integration and would like to add end user documentation to the project. The end user documentation is a user manual, not API documentation. In our environment we use windows, c#, msbuild, cruisecontrol.net and subversion. We are currently using DocToHelp to create our help file, which is based on an msword document. I'm looking for some guidance on how to manage the end user documentation. What documentation tools should I use? Should any of the documentation tools be part of the build script? Should the output files from the documentation tool be stored in subversion? What type of help files would be best to use?

    - by obikodi
    I have spent the last few hours attempting to do this on my own, and using Google to find a solution but to no avail. So if you can help out i would super appreciate it! Basically I have a page which has 3 separate biographies in 'preview mode', which shows only the first paragraph of each bio. When you click on 'read more' for one bio it opens up the 'full mode'. What is happening at the moment, is if i click on one 'read more' link, it opens up the full mode on all 3 bio's. How do i edit the following code so; It only opens the full mode bio of the link i click on Make it reusable so i don't have to duplicate the code 3 times for each bio $("a#btnReadMore").click(function(){ $('.readMoreSlider').slideToggle("fast"); $(this).toggleClass("readMoreSliderActive"); return false; }); Thanks for your help!
