• How do I find Microsoft APIs?

  - by Stephen

  I'm a java programmer, and if I see something that: I don't know about or just want to find a method description without opening an ide or am on support I type java [classname] into google, and there it is. If I try this crazy stunt for C# I'll come up with a whole heap of tutorials (how do I use it etc). If I manage to get to MSDN, I have to wade through a page describing every .net technology to see how their syntax references the same object, and then I have to find the appropriate page from there ([class name] Constructor) for example. This is even more pronounced, because I don't have Visual Studio, so I've got nothing to make it easier. There must be something I'm missing or don't know... how does this situation work for Microsoft developers? how can I make my life easier/searches better? are there techniques that work no matter what computer I'm on (e.g. require no computer setup/downloads) Notes It could be thought that java is just "java", but it's just that the java apis are only referenced/defined in the core language. For all the other languages on the JVM, it's assumed that you will just learn the correct syntax to use the java apis. I presume that .Net only lists a whole heap of languages as the api classes are actually different and have different interfaces capabilities (or some approximation of this presumption). Edit While searching msdn works... in the java space I can type 'java [anyclass]' and it will generally be found... whether it's a java core api or a third party library

• Foosball result prediction

  - by Wolf

  In our office, we regularly enjoy some rounds of foosball / table football after work. I have put together a small java program that generates random 2vs2 lineups from the available players and stores the match results in a database afterwards. The current prediction of the outcome uses a simple average of all previous match results from the 4 involved players. This gives a very rough estimation, but I'd like to replace it with something more sophisticated, taking into account things like: players may be good playing as attacker but bad as defender (or vice versa) players do well against a specific opponent / bad against others some teams work well together, others don't skills change over time What would be the best algorithm to predict the game outcome as accurately as possible? Someone suggested using a neural network for this, which sounds quite interesting... but I do not have enough knowledge on the topic to say if that could work, and I also suspect it might take too many games to be reasonably trained. EDIT: Had to take a longer break from this due to some project deadlines. To make the question more specific: Given the following mysql table containing all matches played so far: table match_result match_id int pk match_start datetime duration int (match length in seconds) blue_defense int fk to table player blue_attack int fk to table player red_defense int fk to table player red_attack int fk to table player score_blue int score_red int How would you write a function predictResult(blueDef, blueAtk, redDef, redAtk) {...} to estimate the outcome as closely as possible, executing any sql, doing calculations or using external libraries?

• Python - Open default mail client using mailto, with multiple recipients

  - by victorhooi

  Hi, I'm attempting to write a Python function to send an email to a list of users, using the default installed mail client. I want to open the email client, and give the user the opportunity to edit the list of users or the email body. I did some searching, and according to here: http://www.sightspecific.com/~mosh/WWW_FAQ/multrec.html It's apparently against the RFC spec to put multiple comma-delimited recipients in a mailto link. However, that's the way everybody else seems to be doing it. What exactly is the modern stance on this? Anyhow, I found the following two sites: http://2ality.blogspot.com/2009/02/generate-emails-with-mailto-urls-and.html http://www.megasolutions.net/python/invoke-users-standard-mail-client-64348.aspx which seem to suggest solutions using urllib.parse (url.parse.quote for me), and webbrowser.open. I tried the sample code from the first link (2ality.blogspot.com), and that worked fine, and opened my default mail client. However, when I try to use the code in my own module, it seems to open up my default browser, for some weird reason. No funny text in the address bar, it just opens up the browser. The email_incorrect_phone_numbers() function is in the Employees class, which contains a dictionary (employee_dict) of Employee objects, which themselves have a number of employee attributes (sn, givenName, mail etc.). Full code is actually here (http://stackoverflow.com/questions/2963975/python-converting-csv-to-objects-code-design) from urllib.parse import quote import webbrowser .... def email_incorrect_phone_numbers(self): email_list = [] for employee in self.employee_dict.values(): if not PhoneNumberFormats.standard_format.search(employee.telephoneNumber): print(employee.telephoneNumber, employee.sn, employee.givenName, employee.mail) email_list.append(employee.mail) recipients = ', '.join(email_list) webbrowser.open("mailto:%s?subject=%s&body=%s" % (recipients, quote("testing"), quote('testing')) ) Any suggestions? Cheers, Victor

• C# String.Replace with a start/index (Added my (slow) implementation)

  - by Chris T

  I'd like an efficient method that would work something like this EDIT: Sorry I didn't put what I'd tried before. I updated the example now. // Method signature, Only replaces first instance or how many are specified in max public int MyReplace(ref string source,string org, string replace, int start, int max) { int ret = 0; int len = replace.Length; int olen = org.Length; for(int i = 0; i < max; i++) { // Find the next instance of the search string int x = source.IndexOf(org, ret + olen); if(x > ret) ret = x; else break; // Insert the replacement source = source.Insert(x, replace); // And remove the original source = source.Remove(x + len, olen); // removes original string } return ret; } string source = "The cat can fly but only if he is the cat in the hat"; int i = MyReplace(ref source,"cat", "giraffe", 8, 1); // Results in the string "The cat can fly but only if he is the giraffe in the hat" // i contains the index of the first letter of "giraffe" in the new string The only reason I'm asking is because my implementation I'd imagine getting slow with 1,000s of replaces.

• C# vs C - Big performance difference

  - by John

  I'm finding massive performance differences between similar code in C anc C#. The C code is: #include <stdio.h> #include <time.h> #include <math.h> main() { int i; double root; clock_t start = clock(); for (i = 0 ; i <= 100000000; i++){ root = sqrt(i); } printf("Time elapsed: %f\n", ((double)clock() - start) / CLOCKS_PER_SEC); } And the C# (console app) is: using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication2 { class Program { static void Main(string[] args) { DateTime startTime = DateTime.Now; double root; for (int i = 0; i <= 100000000; i++) { root = Math.Sqrt(i); } TimeSpan runTime = DateTime.Now - startTime; Console.WriteLine("Time elapsed: " + Convert.ToString(runTime.TotalMilliseconds/1000)); } } } With the above code, the C# completes in 0.328125 seconds (release version) and the C takes 11.14 seconds to run. The c is being compiled to a windows executable using mingw. I've always been under the assumption that C/C++ were faster or at least comparable to C#.net. What exactly is causing the C to run over 30 times slower? EDIT: It does appear that the C# optimizer was removing the root as it wasn't being used. I changed the root assignment to root += and printed out the total at the end. I've also compiled the C using cl.exe with the /O2 flag set for max speed. The results are now: 3.75 seconds for the C 2.61 seconds for the C# The C is still taking longer, but this is acceptable

• How do you rotate a sprite around its center by caclulating a new x and y position?

  - by Sam152

  I'm using Dark GDK and C++ to create a simple 2d game. I'm rotating an object but it rotates from the top left corner of the sprite. I have the following variables available: PlayerX PlayerY PlayerWidth PlayerHeight RotateAngle (360 x 0) Is there an algorithm that will modify the pivot point of the sprite, preferable to the center? Here is a small code sample: void Player::Move( void ) { if ( checkLeft() ) { PlayerX -= PlayerSpeed; if ( PlayerX < 0 ) PlayerX = 0; } if ( checkRight() ) { PlayerX += PlayerSpeed ; if ( PlayerX > 800 - PlayerWidth ) PlayerX = 800 - PlayerWidth; } if ( checkUp()) { PlayerY -= PlayerSpeed; if ( PlayerY < 0 ) PlayerY = 0; } if ( checkDown()) { PlayerY += PlayerSpeed; if ( PlayerY > 600 - PlayerHeight) PlayerY = 600 - PlayerHeight; } RotateAngle += 5; if(RotateAngle > 360) RotateAngle -=360; dbRotateSprite(Handle,RotateAngle); dbSprite ( 1 , PlayerX , PlayerY , Handle ); } Edit I'm considering opening up some reputation for this question, I have yet to be provided with an answer that works for me. If someone can provide an actual code sample that does the job, I'd be very happy. The problem with Blindy's answer is that no matter how much I simply translate it back or forth, the spirte still rotates around the top left hand corner and moving it somewhere rotating around the top left corner, then moving it back to the same position accomplishes nothing. Here is what I believe to be going on: Just so there is no confusion I have created a an image of what is going on. The left shows what is actually happening and the right shows what I need to happen.

• Could Python's logging SMTP Handler be freezing my thread for 2 minutes?

  - by Oddthinking

  A rather confusing sequence of events happened, according to my log-file, and I am about to put a lot of the blame on the Python logger, which is a bold claim. I thought I should get some second opinions about whether what I am saying could be true. I am trying to explain why there is are several large gaps in my log file (around two minutes at a time) during stressful periods for my application when it is missing deadlines. I am using Python's logging module on a remote server, and have set-up, with a configuration file, for all logs of severity of ERROR or higher to be emailed to me. Typically, only one error will be sent at a time, but during periods of sustained problems, I might get a dozen in a minute - annoying, but nothing that should stress SMTP. I believe that, after a short spurt of such messages, the Python logging system (or perhaps the SMTP system it is sitting on) is encountering errors or congestion. The call to Python's log is then BLOCKING for two minutes, causing my thread to miss its deadlines. (I was smart enough to move the logging until after the critical path of the application - so I don't care if logging takes me a few seconds, but two minutes is far too long.) This seems like a rather awkward architecture (for both a logging system that can freeze up, and for an SMTP system (Ubuntu, sendmail) that cannot handle dozens of emails in a minute**), so this surprises me, but it exactly fits the symptoms. Has anyone had any experience with this? Can anyone describe how to stop it from blocking? ** EDIT: I actually counted. A little under 4000 short emails in two hours. So far more than I suggested, sorry. But enough to over-fill a Sendmail's buffers?

• DataGrid: dynamic DataTemplate for dynamic DataGridTemplateColumn

  - by Lukas Cenovsky

  I want to show data in a datagrid where the data is a collection of public class Thing { public string Foo { get; set; } public string Bar { get; set; } public List<Candidate> Candidates { get; set; } } public class Candidate { public string FirstName { get; set; } public string LastName { get; set; } ... } where the number of candidates in Candidates list varies at runtime. Desired grid layout looks like this Foo | Bar | Candidate 1 | Candidate 2 | ... | Candidate N I'd like to have a DataTemplate for each Candidate as I plan changing it during runtime - user can choose what info about candidate is displayed in different columns (candidate is just an example, I have different object). That means I also want to change the column templates in runtime although this can be achieved by one big template and collapsing its parts. I know about two ways how to achieve my goals (both quite similar): Use AutoGeneratingColumn event and create Candidates columns Add Columns manually In both cases I need to load the DataTemplate from string with XamlReader. Before that I have to edit the string to change the binding to wanted Candidate. Is there a better way how to create a DataGrid with unknown number of DataGridTemplateColumn? Note: This question is based on dynamic datatemplate with valueconverter

• Exiting from the Middle of an Expression Without Using Exceptions

  - by Jon Purdy

  Is there a way to emulate the use of flow-control constructs in the middle of an expression? Is it possible, in a comma-delimited expression x, y, for y to cause a return? Edit: I'm working on a compiler for something rather similar to a functional language, and the target language is C++. Everything is an expression in the source language, and the sanest, simplest translation to the destination language leaves as many things expressions as possible. Basically, semicolons in the target language become C++ commas. In-language flow-control constructs have presented no problems thus far; it's only return. I just need a way to prematurely exit a comma-delimited expression, and I'd prefer not to use exceptions unless someone can show me that they don't have excessive overhead in this situation. The problem of course is that most flow-control constructs are not legal expressions in C++. The only solution I've found so far is something like this: try { return x(), // x(); (1 ? throw Return(0) : 0); // return 0; } catch (Return& ret) { return ref.value; } The return statement is always there (in the event that a Return construct is not reached), and as such the throw has to be wrapped in ?: to get the compiler to shut up about its void result being used in an expression. I would really like to avoid using exceptions for flow control, unless in this case it can be shown that no particular overhead is incurred; does throwing an exception cause unwinding or anything here? This code needs to run with reasonable efficiency. I just need a function-level equivalent of exit().

• How to have a where clause on an insert or an update in Linq to Sql?

  - by Kelsey

  I am trying to convert the following stored proc to a LinqToSql call (this is a simplied version of the SQL): INSERT INTO [MyTable] ([Name], [Value]) SELECT @name, @value WHERE NOT EXISTS(SELECT [Value] FROM [MyTable] WHERE [Value] = @value) The DB does not have a constraint on the field that is getting checked for so in this specific case the check needs to be made manually. Also there are many items constantly being inserted as well so I need to make sure that when this specific insert happens there is no dupe of the value field. My first hunch is to do the following: using (TransactionScope scope = new TransactionScope()) { if (Context.MyTables.SingleOrDefault(t => t.Value == in.Value) != null) { MyLinqModels.MyTable t = new MyLinqModels.MyTable() { Name = in.Name, Value = in.Value }; // Do some stuff in the transaction scope.Complete(); } } This is the first time I have really run into this scenario so I want to make sure I am going about it the right way. Does this seem correct or can anyone suggest a better way of going about it without having two seperate calls? Edit: I am running into a similar issue with an update: UPDATE [AnotherTable] SET [Code] = @code WHERE [ID] = @id AND [Code] IS NULL How would I do the same check with Linqtosql? I assume I need to do a get and then set all the values and submit but what if someone updates [Code] to something other than null from the time I do the get to when the update executes? Same problem as the insert...

• Cocoa UI Elements Not Updating

  - by spamguy

  I have a few Cocoa UI elements with outlet connexions to an object instantiated within an NSView object, which is in turn put there by an NSViewController. These elements, a definite progress bar and a text label, are not updating: the progress bar is dead and empty despite having its value change constantly, the text label does not unhide through [textLabel setHidden:NO], the text label does not change its string. What I know: There's no difference between binding values and setting them in code. Nothing changes either way. I've checked outlet connections. They're all there. I've tried [X displayIfNeeded], where X has been the UI objects themselves, the containing NSView, and the main window. No difference. [progressBar setUsesThreadedAnimation:YES] makes no difference. Interestingly, if I look at progressBar mid-program, _threadedAnimation is still NO. The object holding all these outlets and performing an import operation is in an NSOperationQueue owned by the NSViewController object. Thanks! EDIT: As suggested, I called [self performSelectorOnMainThread:@selector(updateProgress:) withObject:[NSNumber numberWithInt:myObject] waitUntilDone:NO]. (I've also tried waitUntilDone:YES.) It's still not updating. The debugger clearly shows updateProgress: taking place in the main thread, so I don't know what's missing.

• curl: downloading from dynamic url

  - by adam n

  I'm trying to download an html file with curl in bash. Like this site: http://www.registrar.ucla.edu/schedule/detselect.aspx?termsel=10S&subareasel=PHYSICS&idxcrs=0001B+++ When I download it manually, it works fine. However, when i try and run my script through crontab, the output html file is very small and just says "Object moved to here." with a broken link. Does this have something to do with the sparse environment the crontab commands run it? I found this question: http://stackoverflow.com/questions/1279340/php-ssl-curl-object-moved-error but i'm using bash, not php. What are the equivalent command line options or variables to set to fix this problem in bash? (I want to do this with curl, not wget) Edit: well, sometimes downloading the file manually (via interactive shell) works, but sometimes it doesn't (I still get the "Object moved here" message). So it may not be a a specifically be a problem with cron's environment, but with curl itself. the cron entry: * * * * * ~/.class/test.sh >> ~/.class/test_out 2>&1 test.sh: #! /bin/bash PATH=/usr/local/bin:/usr/bin:/bin:/sbin cd ~/.class course="physics 1b" url="http://www.registrar.ucla.edu/schedule/detselect.aspx?termsel=10S<URL>subareasel=PHYSICS<URL>idxcrs=0001B+++" curl "$url" -sLo "$course".html --max-redirs 5 As I was searching around on google, someone suggested that the problem might happen because there are parameters in the url. (Because it is a dynamic url?)

• ListView Final Column Autosize creates scrollbar

  - by Courtney de Lautour

  Hi There, I am implementing a custom control which derives from ListView. I would like for the final column to fill the remaining space (Quite a common task), I have gone about this via overriding the OnResize method: protected override void OnResize(EventArgs e) { base.OnResize(e); if (Columns.Count == 0) return; Columns[Columns.Count - 1].Width = -2; // -2 = Fill remaining space } or via another method: protected override void OnResize(EventArgs e) { base.OnResize(e); if (!_autoFillLastColumn) return; if (Columns.Count == 0) return; int TotalWidth = 0; int i = 0; for (; i < Columns.Count - 1; i++) { TotalWidth += Columns[i].Width; } Columns[i].Width = this.DisplayRectangle.Width - TotalWidth; } Edit: This works fine until I dock the ListView into a parent container and resize via that control. Every second time the control size shrinks (IE, drag the the border one pixel), I get a scroll bar on the bottom which can't move at all (not even one pixel). The result of which is when I drag the size of the parent I am left with a flickering scroll bar in the ListView, and a 50% chance it will be there when the dragging stops.

• How to get smartcard reader name in Windows 7 using C# or C/C++?

  - by AndrejaKo

  Hi! I'm trying to make a C# program which will use a C .dll (unfortunately, the .dll doesn't have good documentation) to access a smart card. One of the functions of the .dll uses name of the reader as argument. My problem is that I don't know how to get the name. After looking for answers I found something similar to what I need in an example here: http://msdn.microsoft.com/en-us/library/aa379803%28VS.85%29.aspx I'm looking for a way to get szReader value as described in the aforementioned example using C#. Can anyone help me or at least point me in the right direction? EDIT: Looks like nobody knows the answer so I'll expand the question: How do I get smartcard reader name using C/C++ and Windows API? I've read through MSDN site for smartcard API, but I couldn't find the function which will list readers. My idea is now to make a C/C++ .dll which will get in-between the smartcard .dll and C# program. It will produce list of readers, let user chose one and call the smartcard .dll using chosen name as argument.

• Returning a CSS element

  - by TMP

  Is there a way to return a CSS element? I was using Adobe Edge and adding some of my own code in their code tab, but in order to create boundaries I would need to keep track of margin-top or margin-left. The following code works to move the element "woo" but I'm not sure how to call the elements to add something like "|| sym.$("woo").css({"margin-left"0px"}) to the move left code. //Move RIGHT if (e.which == 39) { sym.$("woo").css({"margin-left":"+=10px"}); } //Move UP else if (e.which == 38) { sym.$("woo").css({"margin-top":"-=10px"}); } //Move Left else if (e.which == 37) { sym.$("woo").css({"margin-left":"-=10px"}); } //Move DOWN else if (e.which == 40) { sym.$("woo").css({"margin-top":"+=10px"}); } EDIT: I changed the Left if statement to the following: else if (e.which == 37 && ($("woo").css("margin-left")>0)) { It seems to be working to some extent except for now it won't move left at all! I tried doing <0 too in case I was screwing up a sign but it won't let me move the element left either.

• Reading Code - helpful visualizers and browser tools

  - by wishi_

  Hi! I find myself reading 10 times more code than writing. My IDEs all are optimized to make me edit code - with completion, code assist, outlines etc. However if I'm checking out a completely new project: getting into the application's logics isn't optimized with these IDE features. Because I cannot extend what I don't fully understand. If you for example check out a relatively new project, frama-c, you realize that it has got plugins that are helpful to gain insight into "unfamiliar code": http://frama-c.com/plugins.html - However of course the project has a different scope. What I'm fully aware of. I'm looking for something that does helpful things for code-reading. Like: providing a graph, - reverse engineering UML e g., showing variable scopes showing which parts are affected by attempted modifications visualizing data-flow semantics showing tag-lists of heavily utilized functions ... My hope is that something like that exists. - That there're some Eclipse plugins I don't know or that there's a code-browser that has some of these features?

• Return an empty collection when Linq where returns nothing

  - by ahsteele

  I am using the below statement with the intent of getting all of the machine objects from the MachineList collection (type IEnumerable) that have a MachineStatus of i. The MachineList collection will not always contain machines with a status of i. At times when no machines have a MachineStatus of i I'd like to return an empty collection. My call to ActiveMachines (which is used first) works but InactiveMachines does not. public IEnumerable<Machine> ActiveMachines { get { return Customer.MachineList .Where(m => m.MachineStatus == "a"); } } public IEnumerable<Machine> InactiveMachines { get { return Customer.MachineList .Where(m => m.MachineStatus == "i"); } } Edit Upon further examination it appears that any enumeration of MachineList will cause subsequent enumerations of MachineList to throw an exeception: Object reference not set to an instance of an object. Therefore, it doesn't matter if a call is made to ActiveMachines or InactiveMachines as its an issue with the MachineList collection. This is especially troubling because I can break calls to MachineList simply by enumerating it in a Watch before it is called in code. At its lowest level MachineList implements NHibernate.IQuery being returned as an IEnumerable. What's causing MachineList to lose its contents after an initial enumeration?

• UISlider how to set the initial value

  - by slim

  I'm pretty new at this iphone dev stuff and i'm working on some existing code at a company. The uislider i'm trying to set the initial value on is actually in a UITableViewCell and is a custom control. I was thinking in the cell init cell = (QuantitiesCell *)[self loadCellWithNibName:@"QuantitiesCell" forTableView:ltableView withStyle:UITableViewCellStyleDefault]; i could just call something like ((QuantitiesCell *)cell).value = 5; The actual QuantitiesCell class has the member value and the following functions -(void)initCell;{ if (listOfValues == nil) { [self initListOfValues]; } quantitiesSLider.maximumValue = [listOfValues count]-1; quantitiesSLider.minimumValue = 0; quantitiesSLider.value = self.value; } -(void)initListOfValues;{ listOfValues = [[NSMutableArray alloc] initWithCapacity:10]; int j =0; for (float i = minValue; i <= maxValue+increment; i=i+increment) { [listOfValues addObject:[NSNumber numberWithFloat: i]]; if (i == value) { quantitiesSLider.value = j; } j++; } } like i said, i'm pretty new at this so if i need to post more of the code to show whats going to get help, let me know, This slider always is defaulting to 1, the slider ranges usually from 1-10, and i want to set it to a specific value of the item i'm trying to edit.

• How to get rid of Internet Explorer 7 reloading on fragment change

  - by Philippe Beaudoin

  I have an anchor <a href="#!admin">General</a> somewhere in my page. Clicking this in any browser but IE7 (haven't tried IE6) causes no page reload, as expected. However, under IE7 it reloads the page as soon as it's clicked. The strangest thing is that I have the exact same anchor elsewhere in the page and it causes no reload. The only difference I can see between these is a slight difference in style, and the fact that the faulty anchor is deeply nested in divs, where the other is closer to the top. My questions: Is this a known bug with IE7? If so, is there any work around? If not, any clue as to what might be going wrong? Edit: If you want to see this yourself, go to http://filouguestbook.appspot.com/#!main sign-in with a google account and click on the Settings link the the top bar. Switch between the General and Accounts pages, the app will reload. From the Accounts page, click on Settings in the top bar, this will switch tab but not reload!

• How do I get Ctrl-Backspace to delete a word in vim within gnome-terminal?

  - by Michael Gundlach

  I'd like Ctrl-Backspace to delete the current word in vim insert mode. From within xterm I can pull this off via :inoremap <C-H> <C-W> but in gnome-terminal I cannot figure out a way to make it happen. When in vim insert mode, if I type control-v and then press backspace, I get ^H in xterm, and ^? in gnome-terminal. Unfortunately, :inoremap <C-?> <C-W> doesn't do the trick in gnome-terminal; control-backspace just erases a single character no matter what. Regarding ASCII codes: Gnome-terminal lets you change the backspace character under Edit - Profile Preferences - Compatibility. Unfortunately, no option works, as far as I can tell: whatever character I apply to Backspace via the settings, if I try mapping the character itself, like :inoremap <C-H> <C-W> then regular backspace and control-backspace both erase an entire word; and if I try mapping control plus that character, like :inoremap <C-^H> <C-W> then regular backspace and control-backspace just erase a single character.

This is what I'm currently doing: https://developer.mozilla.org/en/XPCOM_Interface_Reference/nsIScriptableIO downloadFile: function(httpLoc) { try { //new obj_URI object var obj_URI = Cc["@mozilla.org/network/io-service;1"].getService(Ci.nsIIOService). newURI(httpLoc, null, null); //new file object //set file with path obj_TargetFile.initWithPath("C:\\javascript\\cache\\test.pdf"); //if file doesn't exist, create if(!obj_TargetFile.exists()) { obj_TargetFile.create(0x00,0644); } //new persitence object var obj_Persist = Cc["@mozilla.org/embedding/browser/nsWebBrowserPersist;1"]. createInstance(Ci.nsIWebBrowserPersist); // with persist flags if desired const nsIWBP = Ci.nsIWebBrowserPersist; const flags = nsIWBP.PERSIST_FLAGS_REPLACE_EXISTING_FILES; obj_Persist.persistFlags = flags | nsIWBP.PERSIST_FLAGS_FROM_CACHE; //save file to target obj_Persist.saveURI(obj_URI,null,null,null,null,obj_TargetFile); return true; } catch (e) { alert(e); } },//end downloadFile As you can see the directory is hardcoded in there, I want to save the pdf file open in the active tab to a relative temporary directory, or anywhere that's out of the way enough that the user won't stumble along and delete it. I'm going to try that using File I/O, I was under the impression that what I was looking for was in scriptable file I/O and thus disabled.

• Super simple CSS tooltip in a table, why is it not displaying and can I make it work?

  - by Kyle Sevenoaks

  Hi, I have been trying to implement many different tooltips on this page for my client, he's adamant that we have a picture of the product show up when you hover over the product name in the order page. I decided to use the super simple CSS tooltip, it's very easy to implement and does exactly what we want. It works on a dynamic page, the others I tried didn't. I have made an example here: CSS tooltip in table example. This page used to be displayed using divs, I have since changed it to a table, as it's tabular data and easier to work with. It worked fine when it used divs, now it's in a table, it won't display the span on hover. My questions are: Why is it not working? How can I make it work? If not, does anyone know another super easy to implement tooltip that can work properly on a dynamic page? Here's the DIV tooltip for reference: DIV display tooltip. Edit: Just noticed it kinda half works in IE8. Thanks.

• Form submitted via dialog opens dialog again

  - by VikingGoat

  I have a form in a jquerymobile dialog box that I am submitting via jQuery Ajax. Currently my problem is that once the form is submitted the same dialog box is opened again on top of the original dialogbox. So that my url reads before submission: url/index.php#&ui-state=dialog and then after submission: url/index.php#&ui-state=dialog#&ui-state=dialog&ui-state=dialog Has anyone ever encountered something like this before? [edit added code example] $(function(){ $("#form").submit(function(e){ e.preventDefault(); var dataString = $("#form").serialize(); errorInput = $("input[name=valOne]#valOne").val(); $.ajax({ type: "GET", url: "formHandler.php", data: dataString, dataType: "text", success: function(data){ if(data.toLowerCase().indexOf("error") >= 0){ alert(data); $(".ui-dialog").dialog("close"); $("#valOne").val(errorInput); //the reentering info so user doesn't have to }else{ $(".ui-dialog").dialog("close"); location.href="index.php"; } }, error:function (xhr, ajaxOptions, thrownError){ alert(thrownError); } }); }); });

• Looking for good PHP editor or IDE with 'IntelliSense'

  - by Andrew

  Hello, I'm looking for suitable PHP Editor or IDE with syntax auto-completion. I've tried trial versions of programs like Zend Studio, PHPDesigner, NetBeans PHP, NuSphere PhpED, and similar -- but none of them fully satisfied me. I quite liked hint window with detailed info about what function does and what it returns. Also I liked the way NetBeans auto-complete code (for example inserts all required parameters in function declaration as "dummy fields" and then you can jump between them using TAB in order to edit them). On the other hand, environment of NetBeans doesn't belong to the nicest. In this regard I prefer PHPDesigner with its sleek and light interface. At this moment I don't use any of the debugging options, since I don't know yet how to use profiller, breakpoints, watches and what not, so at this point my only concern is good autocompletion. For this purpose NetBean would be great choice, but with future in mind I am not sure debugging will be good in NetBeans, especially as I would prefer to use remote Linux server for this. So in short, I'm looking for editor that: Have similar code auto-completion (IntelliSense) like NetBeans Allow you to debug code using remote server (or sets up own debugging server like PHPDesigner does) without need to run Apache and similar on local computer Is preferably easy to use / intuitive interface Any ideas?
