• Best way to do syntax highlighting in GTK+?

  - by Tyler

  I was wondering if someone could point me to an example of (or just their thoughts on) the best way to code syntax highlighting in a C-based GTK+ application. I know that I can use the GtkTextTag to modify text in a GtkTextBuffer but beyond searching out keywords (iteratively or by regexing the string) is there a better way? My only concern is that if I wipe all of the tags and then re-search and apply the tags at every text change event it could really bog down my application. As always thanks for your help!

• Actionscript Receiving Mouse Events For Lower Indexed And Partially Covered Display Objects?

  - by Chunk1978

  i have 2 sprites on stage. bottomSprite is added to the display list first, followed by topSprite. topSprite partially covers bottomSprite. i've added an event listener to bottomSprite for MouseEvent.MOUSE_MOVED notifications to simply trace the mouseX and mouseY coordinates. however, the notification doesn't work for the parts of bottomSprite that are covered by topSprite. var bottomSprite:Sprite = new Sprite(); bottomSprite.graphics.beginFill(0x666666, 0.5); bottomSprite.graphics.drawRect(150,150, 150, 150); bottomSprite.graphics.endFill(); addChild(bottomSprite); var topSprite:Sprite = new Sprite(); topSprite.graphics.beginFill(0x00FFFF, 0.5); topSprite.graphics.drawRect(250,50, 150, 150); topSprite.graphics.endFill(); addChild(topSprite); bottomSprite.addEventListener(MouseEvent.MOUSE_MOVE, traceCoords); function traceCoords(evt:MouseEvent):void { trace ("Coord = X:" + bottomSprite.mouseX + ", Y:" + bottomSprite.mouseY); }

• Rsspnse.redirect will not redirect on Internet explorer

  - by Amit

  Hi, I am using Response.Redirect("someurl",true); in the page_preInit event to redirect all the requests that come to a page. It works fine on Firexox, but if i access the page from internet explorer 7/8, it says page can not be found and will not redirect to new URL. Any idea why this happens?? Update: I tried giving a radom URL in the redirect such as google.com and it works fine. Actually the URL I am trying to redirect is not accessible on my machine, it is on another VPN. I guess IE will not change the URL on the addressbar if it can not access the URL. Firefox on the other hand changes the address on the address bar.

• passing paramters to component in flex

  - by dubbeat

  Hi, I've got 2 files, my Application and a custom component. In my component I have a httpservice and a string named _requestUrl that is bindable. The httpservice uses this. <mx:HTTPService id="srv" url="{_requestUrl}" result="parseHttpResult(event)" resultFormat="xml" method="GET" useProxy="false"> </mx:HTTPService> In my application file I make an instance of my component in the onCreationComplete function. In this function if I say mycomponent._urlRequest ="http://mysite.com" the httpservice throws a null url error but if I say mycomponent.srv.url="http://mysite.com" it works fine. Why is this?

• NTLM Authentication fails ONLY with IE against 2k8 App server behind 2k8 IIS7 Reverse Proxy

  - by CptSkippy

  I'm developing an ASP.NET application for an intranet site that is using Windows/NTLM/WIA/whatever authentication. The application is hosted on a Windows 2k8 server but is accessed through a Reverse Proxy using IIs7 on another 2k8 machine. Authentication works fine in FireFox, Chrome and Safari but fails in IE8. If I circumvent the Proxy and access the application server directly then it works fine so it has something to do with proxy. There's nothing in the Event Viewer on any of the 3 machines to indicate what might be happening. If you connect using IE8 it prompts for your credentials instead of automatically passing them, yes I've setup an explicit trust over an above the domain trust, but it still errors out with a 401 error returned from the proxy. Any ideas where to start troubleshooting this?

• OpenSSH connection trouble

  - by gnostical

  Hi, I'm trying to use Putty 0.60 to log in to an OpenSSH 5.3 server. Connections with openssh from another Linux server are possible, but Putty fails. Putty's event log tells me "software caused connection abort" right after the DH key exchange, the server log doesn't report anything (set to INFO). I analyzed the traffic with Wireshark and got a whole bunch of "TCP retransmission" and "TCP DUP ACK" after said key exchange. Sometimes I was able to log in, but at some point (usually < 2 min.) the connection froze without any logged messages. Sadly, I didn't capture a trace. The server is my own (Funtoo with genkernel and gentoo-sources 2.6.34), so I may tweak it, but I'd still like to know what causes the error. Any suggestions? Thank you!

• Showing/Hiding windows iPhone Dev

  - by Cal S

  In my iPhone app I am developing, I have defined two windows: @interface The_NoteAppDelegate : NSObject <UIApplicationDelegate> { IBOutlet UIWindow *newNoteWindow; IBOutlet UIWindow *homeWindow; } @property (nonatomic, retain) UIWindow *newNoteWindow; @property (nonatomic, retain) UIWindow *homeWindow; and they are linked correctly in IB - but how do I show/hide these windows? [homeWindow makeKeyAndVisible]; works in appDidFinishLaunching but when I try [newNoteWindow makeKeyAndVisible]; again to open the other window (on a button touch event) in front of the other, the app freezes. I know this is a very n00by question but please help me out :)

• assistance with fxcop

  - by amateur

  I am at present developing a mvc4 project that comunicates to a set of wcf services. I am setting such up in tfs build for a team of developers. I am very much a newbie to fxcop and code analysis in general. I am currently researching it and have some questions following this: Is it recommended to use the rules that come with fxcop? Should it be included as a build task during builds? What is the value from it? Are there guidelines to what rules to abide by or is it best to go with the default? Is it correct to run the analysis as a post build event? I am a newbie to fxcop and would like some feedback. I am as it is integrating stylecop in to my build.

• How do I detect whether a browser supports mouseover events?

  - by Damovisa

  Let's assume I have a web page which has some onmouseover javascript behaviour to drop down a menu (or something similar) Obviously, this isn't going to work on a touch device like the iPad or smartphones. How can I detect whether the browser supports hover events like onmouseover or onmouseout and the :hover pseudotag in CSS? Note: I know that if I'm concerned about this I should write it a different way, but I'm curious as to whether detection can be done. Edit: When I say, "supports hover events", I really mean, "does the browser have a meaningful representation of hover events". If the hardware supports it but the software doesn't (or vice versa), there's no meaningful representation. With the exception of some upcoming tech, I don't think any touch devices have a meaningful representation of a hover event.

  - by yishai neeman

  I am building a website now for a library and i need to check every day at the same time if there are people who need to return their books in the next five days and to send them a reminder via email. My question is what will be the correct way to do that? What i need to accomplish is when the specific time of day comes i need to run an sql stored procedure and check either through visual studio 2010 or any other way if the stored procedure has returned any results to which i need to email. Is there a way to maybe check the system time constantly on C# and not as a triggered event?

• Put a program in the system tray at startup

  - by cosmo0

  Hi I followed the commonly-linked tip for reducing an application to the system tray : http://www.developer.com/net/csharp/article.php/3336751 Now it works, but there is still a problem : my application is shown when it starts ; I want it to start directly in the systray. I tried to minimize and hide it in the Load event, but it does nothing. Edit : I could, as a poster suggested, modify the shortcut properties, but I'd rather use code : I don't have complete control over every computer the soft is installed on. I don't want to remove it completely from everywhere except the systray, I just want it to start minimized. Any ideas ? Thanks

• jQuery slider widget background -- change dynamicaly

  - by publicRavi

  I use a custom background for my slider by overriding the CSS: .ui-widget-content {background: transparent url(../img/bg.png) no-repeat;} Slider's behavior is controlled by: $(document).ready(function() { $(".myslider5").slider({ animate: "true", step: 1, min: -1950, max: 1950, value: 0, slide: function(event, ui) { // magic happens here } }); There is a need for me to use 2 different classes for my slider DIV, based on some logic. So, myslider5 and myslider3 are the two classes. But their background images need to change too. How do I go about doing this?

• Bind jQuery UI autocomplete using .live()

  - by seth.vargo

  I've searched everywhere, but I can't seem to find any help... I have some textboxes that are created dynamically via JS, so I need to bind all of their classes to an autocomplete. As a result, I need to use the new .live() option. As an example, to bind all items with a class of .foo now and future created: $('.foo').live('click', function(){ alert('clicked'); }); It takes (and behaves) the same as .bind(). However, I want to bind an autocomplete... This doesn't work: $('.foo').live('autocomplete', function(event, ui){ source: 'url.php' // (surpressed other arguments) }); How can I use .live() to bind autocomplete? UPDATE Figured it out with Framer: $(function(){ $('.search').live('keyup.autocomplete', function(){ $(this).autocomplete({ source : 'url.php' }); }); });

• Creating C# form fields with events based off of a text file

  - by evolve

  I need to generate windows form fields based off of a text file that I am parsing. I also want to automatically generate validation event handlers which all will be basically the same only the form field and the regular expression which is used to validate the field will change. I'm having a difficult time figuring out the quickest and easiest method to go about doing this. Any pointers in the right direction would really be great, maybe even some keywords that I'm missing. I can only imagine this type of question has been covered before, I just don't know what I'm searching for really.

• Parse both symbols . and , as decimal digits delimiter in ASP.NET

  - by abatishchev

  I'm writing a banking system and my customer wants support both Russian and American numeric standards in decimal digits delimiter. Respectively . and ,. Now only , works properly. Perhaps because of web server's OS format (Russian is set). String like 2000.00 throws a FormatException: Input string was not in a correct format. How to fix that? Are there any other ideas except String.Replace('.', ',') on FormView.ItemInserting event?

• C signal parent process from child

  - by Gary

  I'm trying to solve a problem I've got where a child process runs execvp() and needs to let the parent know if it returns. So, after the execvp() returns (because there's been an error), how can I tell the parent that this particular event has happened so it can handle it. There's one method of writing a string of text through the pipe I'm using and then reading that from the parent.. but it seems a bit sloppy. Is there a better way? Thanks!

• API For Flex Apps To Interact

  - by dimo414

  I have a large flex application (the app) running on one server, and many small flex applications (widgets) running on another server, which are to be included in the app so that visually the user see's one continuous application. Due to proprietary third party software, this structure cannot be changed. I am looking for some way to allow the app and the widgets to communicate, allowing the app to make changes to the widgets and the the widgets to notify the app when events are triggered, so that user interaction is fluid and continuous. There are a few related questions which indicate it's possible to do this by setting up event triggers and listeners. I am wondering if there is any standardized way to do this (the answers aren't very clear) or if anyone has developed a library or API to make this easier.

• How to subscribe to EventHandler of a private control outside of Form

  - by randooom

  Hi all, maybe my design is not good, or I don't see the obvious solution, but I want to subscribe to a buttonClick EventHandler of Form1 from outside form1. For example I have a Controller and Form1 who are both instanced in the main function. Now I want to subscribe a function from Controller to the buttonClick event from Button1_Click in Form1. But the button1 is declarded private, so i can't do form1->Button1->Click += gcnew EventHandler(controller->function) Is there any way to get around this? Ok I could write a setter or something in Form1, but is there any other solution? I read some examples, but they are all calling events from within the same class so they don't address my specific problem.

In other words is there any way to distinguish between the mouse scroll high and normal speed. Any advice will be appreciated.
