  • Gui's with Win32 API

    - by user146780
    I'm wondering what the correct way of creating Gui's in with Win32 API. Right now I just call the CreateWindowEx in my WM_CREATE event, but I don't think this is the right way to do it. Just as an example, what would be the correct way of adding a 100x20 EditField and getting text from it? Would you create it on WM_Create then use GetText()? Thanks

  • Problem inserting JavaScript into a CKEditor Instance running inside a jQuery-UI Dialog Box

    - by PlasmaFlux
    Hello Overflowers! Here's what's going on: I'm building an app (using PHP, jQuery, etc), part of which lets users edit various bits of a web page (Header, Footer, Main Content, Sidebar) using CKEditor. It's set up so that each editable bit has an "Edit Content" button in the upper right that, on click, launches an instance of CKEditor inside a jQuery-UI Dialog box. After the user is done editing, they can click an 'Update Changes' button that passes the edited content back off to the main page and closes the Dialog/CKeditor. It's all working magnificently, save for one thing. If someone inserts any JavaScript code, wrapped in 'script' tags, using either the Insert HTML Plugin for CKEditor or by going to 'Source' in CKEditor and placing the code in the source, everything seems okay until they click the 'Update Changes' button. The JavaScript appears to be inserting properly, but when 'Update Changes' is clicked, instead of the Dialog closing and passing the script back into the div where it belongs, what I get instead is an all-white screen with just the output of the JavaScript. For example, a simple 'Hello World' script results in a white screen with the string 'Hello World' in the upper left corner; for more intricate scripts, like an API call to, say Aweber, that generates a newsletter signup form, I get an all-white screen with the resulting form from the Aweber API call perfectly rendered in the middle of the screen. One of the most confusing parts is that, on these pages, if I click 'View Source', I get absolutely nothing. Blank emptiness. Here's all my code that handles the launching of the CKEditor instance inside the jQuery-UI Dialog, and the passing of the edited data back into its associated div on click of the 'Update Changes' button: $(function() { $('.foobar_edit_button') .button() .click(function() { var beingEdited = $(this).nextAll('.foobar_editable').attr('id'); var content = $(this).nextAll('.foobar_editable').html(); $('#foobar_editor').html(content); $('#foobar_editor').dialog( { open:function() { $(this).ckeditor(function() { CKFinder.SetupCKEditor( this, '<?php echo '/foobar/lib/editor/ckfinder/'; ?>' ); }); }, close:function() { $(this).ckeditorGet().destroy(); }, autoOpen: false, width: 840, modal: true, buttons: { 'Update Changes': function() { // TODO: submit changes to server via ajax once its completed: for ( instance in CKEDITOR.instances ) CKEDITOR.instances[instance].updateElement(); var edited_content = $('#foobar_editor').html(); $('#' + beingEdited).html(edited_content); $(this).dialog('close'); } } }); $('#foobar_editor').dialog('open'); }); }); I'm all sorts of confused. If anyone can point me in the right direction, it will be greatly appreciated. Thanks!

    I am trying to put a "Contract" on a method call. My web application is in Spring 3. Is writing customs Annotations the right way to go. If so, any pointers( I didn't find anything in spring reference docs). Should I use tools like "Modern Jass", JML ...? Again any pointers will be useful. Thanks

  • service not defined when precompiling a web app with AJAX-enabled WCF Service

    - by Omar Mefire
    I created a web application in which one .aspx page calls an AJAX-enabled WCF service (created with Visual Studio 2008 Add New Item - AJAX-enabled WCF Service). when I test the application in Visual Studio, it works and the page can call the service from Javascript but when I "publish" (code precompilation using Visual Studio) it to the local IIS Server, I get an error : "service ThunServ is undefined" in my .html page. I've been spending quite a time to solve this problem but to no avail. Attarea.

  • How to produce precisely-timed tone and silence?

    - by Bob Denny
    I have a C# project that plays Morse code for RSS feeds. I write it using Managed DirectX, only to discover that Managed DirectX is old and deprecated. The task I have is to play pure sine wave bursts interspersed with silence periods (the code) which are precisely timed as to their duration. I need to be able to call a function which plays a pure tone for so many milliseconds, then Thread.Sleep() then play another, etc. At its fastest, the tones and spaces can be as short as 40ms. It's working quite well in Managed DirectX. To get the precisely timed tone I create 1 sec. of sine wave into a secondary buffer, then to play a tone of a certain duration I seek forward to within x milliseconds of the end of the buffer then play. I've tried System.Media.SoundPlayer. It's a loser because you have to Play(), Sleep(), then Stop() for arbitrary tone lengths. The result is a tone that is too long, variable by CPU load. It takes an indeterminate amount of time to actually stop the tone. I then embarked on a lengthy attempt to use NAudio 1.3. I ended up with a memory resident stream providing the tone data, and again seeking forward leaving the desired length of tone remaining in the stream, then playing. This worked OK on the DirectSoundOut class for a while (see below) but the WaveOut class quickly dies with an internal assert saying that buffers are still on the queue despite PlayerStopped = true. This is odd since I play to the end then put a wait of the same duration between the end of the tone and the start of the next. You'd think that 80ms after starting Play of a 40 ms tone that it wouldn't have buffers on the queue. DirectSoundOut works well for a while, but its problem is that for every tone burst Play() it spins off a separate thread. Eventually (5 min or so) it just stops working. You can see thread after thread after thread exiting in the Output window while running the project in VS2008 IDE. I don't create new objects during playing, I just Seek() the tone stream then call Play() over and over, so I don't think it's a problem with orphaned buffers/whatever piling up till it's choked. I'm out of patience on this one, so I'm asking in the hopes that someone here has faced a similar requirement and can steer me in a direction with a likely solution.

  • Linux: How to find all serial devices (ttyS, ttyUSB, ..) without opening them?

    - by Thomas Tempelmann
    What is the proper way to get a list of all available serial ports/devices on a Linux system? In other words, when I iterate over all devices in /dev/, how do I tell which ones are serial ports in the classic way, i.e. those usually supporting baud rates and RTS/CTS flow control? The solution would be coded in C. I ask because I am using a 3rd party library that does this clearly wrong: It appears to only iterate over /dev/ttyS*. The problem is that there are, for instance, serial ports over USB (provided by USB-RS232 adapters), and those are listed under /dev/ttyUSB*. And reading the Serial-HOWTO at Linux.org, I get the idea that there'll be other name spaces as well, as time comes. So I need to find the official way to detect serial devices. Problem is that there appears none documented, or I can't find it. I imagine one way would be to open all files from /dev/tty* and call a specific ioctl() on them that is only available on serial devices. Would that be a good solution, though? Update hrickards suggested to look at the source for "setserial". Its code does exactly what I had in mind: First, it opens a device with: fd = open (path, O_RDWR | O_NONBLOCK) Then it invokes: ioctl (fd, TIOCGSERIAL, &serinfo) If that call returns no error, then it's a serial dev, apparently. I found similar code here, which suggested to also add the O_NOCTTY option. There is one problem with this approach, though: When I tested this code on BSD Unix (i.e. OSX), it worked as well, however serial devices that are provided thru Bluetooth cause the system (driver) to try to connect to the bluetooth device, which takes a while before it'll return with a timeout error. This is caused by just opening the device. And I can imagine that similar things can happen on Linux as well - ideally, I should not need to open the device to figure out its type. I wonder if there's also a way to invoke ioctl functions without an open, or open a device in a way that it does not cause connections to be made? Any ideas?

  • How to use mmap to point to STL type?

    - by srikfreak
    I have a mmap typecast to a char pointer char *ptr; ptr = (char *)mmap(0, FILESIZE, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0); This was my earlier code. But now I want to use a map instead of char * as the requirements changed. Now, my map is declared as map i_s_map; How do I change my mmap call to point to the map?

  • WCF (REST) multiple host headers with one endpoint

    - by Maan
    I have an issue with a WCF REST service (.NET 4) which has multiple host headers, but one end point. The host headers are for example: xxx.yyy.net xxx.yyy.com Both host headers are configured in IIS over HTTPS and redirect to the same WCF service endpoint. I have an Error Handling behavior which logs some extra information in case of an error. The problem is that the logging behavior only works for one of both URLs. When I first call the .net URL, the logging is only working for requests on the .net URL. When I first call the .com URL (after a Worker Process recycle), it’s only working on requests on the .com URL. The configuration looks like this: <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> <services> <service name="XXX.RemoteHostService"> <endpoint address="" behaviorConfiguration="RemoteHostEndPointBehavior" binding="webHttpBinding" bindingConfiguration="HTTPSTransport" contract="XXX.IRemoteHostService" /> </service> </services> <extensions> <behaviorExtensions> <add name="errorHandling" type="XXX.ErrorHandling.ErrorHandlerBehavior, XXX.Services, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </behaviorExtensions> </extensions> <bindings> <webHttpBinding> <binding name="HTTPSTransport"> <security mode="Transport"> <transport clientCredentialType="None"/> </security> </binding> </webHttpBinding> </bindings> <behaviors> <endpointBehaviors> <behavior name="RemoteHostEndPointBehavior"> <webHttp /> <errorHandling /> </behavior> </endpointBehaviors> </behaviors> …. Should I configure multiple endpoints? Or in which way could I configure the WCF Service so the logging behavior is working for both URLs? I tried several things, also solutions mentioned earlier on StackOverflow. But no luck until now...

  • Best practice for DAO pattern ?

    I've seen a lot of codes use a service-dao pattern , I don't know the origin of this pattern . It force the front layer call service , then delegates some of the service task to dao. I want to ask : Does DAO layer do purely data access related task ? What about exception encapsulation ? Is there other pattern can be used to replace this ?

  • Listing defined functions in bash

    - by Charles Duffy
    I'm trying to write some code in bash which uses introspection to select the appropriate function to call. Determining the candidates requires knowing which functions are defined. It's easy to list defined variables in bash using only parameter expansion: $ prefix_foo="one" $ prefix_bar="two" $ echo "${!prefix_*}" prefix_bar prefix_foo However, doing this for functions appears to require filtering the output of set -- a much more haphazard approach. Is there a Right Way?
