  • CSS filters - sometimes working, sometimes not?

    - by a2h
    I'm on the verge of pulling my hair out over this. Here I have a block of perfectly functioning CSS: #admin .block.mode.off { opacity: 0.25; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(opacity=25)"; filter: progid:DXImageTransform.Microsoft.Alpha(opacity=25); } Meanwhile... Internet Explorer 8 couldn't care less about my filter declarations here: #admin .drop .tabs { margin-bottom: 12px; } #admin .drop .tab { margin-right: 4px; } #admin .drop .tab.off { cursor: pointer; opacity: 0.5; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(opacity=50)"; filter: progid:DXImageTransform.Microsoft.Alpha(opacity=50); } #admin .drop .tab.off:hover { text-shadow: 0px 0px 4px #fff; } #admin .drop .tab.on { cursor: default; text-shadow: 0px 0px 4px #fff; -ms-filter: "progid:DXImageTransform.Microsoft.Glow(color=#fff, strength=4)"; filter: progid:DXImageTransform.Microsoft.Glow(color=#fff, strength=4); } My document shows in IE8 Standards, and I am assuming the developer tools are a load of tuna, because the functioning block shows up in its CSS tab as: filter: progid:DXImageTransform.Microsoft.Alpha(opacity=25); opacity: 0.25 Does anyone have any ideas?

  • C++ Microsoft SAPI: How to set Windows text-to-speech output to a memory buffer?

    - by Vladimir
    Hi all, I have been trying to figure out how to "speak" a text into a memory buffer using Windows SAPI 5.1 but so far no success, even though it seems it should be quite simple. There is an example of streaming the synthesized speech into a .wav file, but no examples of how to stream it to a memory buffer. In the end I need to have the synthesized speech in a char* array in 16 kHz 16-bit little-endian PCM format. Currently I create a temp .wav file, redirect speech output there, then read it, but it seems to be a rather stupid solution. Anyone knows how to do that? Thanks!

  • How would I access the Windows Login (Authentication) API from a C++ Service Application?

    - by Gabriel
    Let us imagine for a moment that I have a piece of hardware that can act as an authentication for a user on a given system. I want to write an application in C++ to run as a service, look for this device and if found log the appropriate user in. I believe I have found the API's I would need to use to perform the hardware and service portions of the application but am having a hard time nailing down a way to create a "real" user login. Is this possible? If so where would I look to find resources on accomplishing this? I think of it as being an analog to fingerprint scanner login type devices.

  • [ZF & jQuery] How can I access an URL using AJAX, receive no response, but just manipulate HTML?

    - by rasouza
    I don't know if it's better used with AJAX (tell me, otherwise) but here is my problem: Assuming i'm using Zend Framework, I have a table with several registries from a database with a delete button on each row. That's like this [...] <tbody> <?php foreach ($row as $reg) { ?> <tr <?php if ($reg['value'] < 0) { echo "class='error'"; } ?>> <td><?php echo $reg['creditor'] ?></td> <td><?php echo $reg['debtor'] ?></td> <td><?php echo $reg['reason'] ?></td> <td>R$ <?php echo number_format(abs($reg['value']), 2, ',', ' ')?></td> <td><a href="#" id="<?php echo $reg['id']; ?>" class="delete"><img src="http://192.168.0.102/libraries/css/blueprint/plugins/buttons/icons/cross.png" alt=""/></a></td> </tr> <?php } ?> </tbody> [...] I would like to .fadeOut() and delete (through the link history/delete/id/ROW_ID ) a table row when clicked in the respective delete button. My deleteAction() has no render. It really shouldn't have one, it just deletes a row in the database. Still, how can I make it happen? I tried: // TR Fading when deleted $('.delete') .click(function() { $.ajax({ type: 'GET', url: 'history/delete/id/'+$(this).attr('id'), success: function() { $(this).parent().parent().fadeOut(); } }); return false; }); without success

  • How to import a macro file (previously exported as .bas file) to Microsoft Word using command line?

    - by Nam Gi VU
    I'm writing a command-line program that has a step in which I need to replace text in a Word file. The replacing task is accomplished using Word macro. What I need to do now is to call this macro from command-line. At the moment we can do this by using the -mMacroName parameter of 'winword.exe', i.e. \winword.exe -mMacroName. But this need the macro to be already available as a global macro. Since I need to run the program on another computer, I need to import the above replacing macro programatically... and I don't know how to do this. Please help.

  • How do I authenticate a Twitter user and access the API without leaving my iPhone app?

    - by thebossman
    I'd like to allow users to send out Tweets from my iPhone app. That's all the functionality I need at the moment. From what I know of the Twitter API, there's a standard authentication mechanism, which allows the developer to include the user's name and password in the request string that the application sends to Twitter. This method will no longer be supported come June 30, 2010. Given the timeframe, the better other choice is oAuth. One of the caveats of oAuth is that it requires a UIWebView to pop up within the app to allow the user to enter his or her credentials or a PIN number. None of the Twitter apps on my phone do this, however: Tweetie, TweetDeck and Twitterific. I assume they're using the first authentication method, but it seems like Twitter wouldn't deprecate an API that would hurt the user experience across the board. There must be an alternative method--what am I missing?

  • How can I access IEnumerable<T> extension methods on my custom subclass of BindingList<T>?

    - by Dan
    I have a custom subclass of BindingList<T> that I want to execute a LINQ query over using the handy extension methods. For example: public int GetSum(MyList<T> list) { return list.Sum(x => x.Value); } But the compiler complains that it can't resolve Sum because it doesn't recognize list as an IEnumerable<T>, which it obviously is, because this works: public int GetSum(MyList<T> list) { return ((IEnumerable<T>)list).Sum(x => x.Value); } Anyone have a clever way I can avoid the ugly and unecessary cast?

Application: Create Mandelbrot Image (GUI) My disptacher works perfektly this this case: private void progressBarRefresh(){ while ((con.Progress) < 99) { progressBar1.Dispatcher.Invoke(DispatcherPriority.Send, new Action(delegate { progressBar1.Value = con.Progress; } )); } } I get the Message (Title) when tring to do this with the below code: bmp = BitmapSource.Create(width, height, 96, 96, pf, null, rawImage, stride); this.Dispatcher.Invoke(DispatcherPriority.Send, new Action(delegate { img.Source = bmp; ViewBox.Child = img; //vllt am schluss } )); I will try to explain how my program works. I created a new Thread (because GUI dont response) for the calculation of the pixels and the colors. In this Thread(Mehtod) I´m using the Dispatcher to Refresh my Image in the ViewBox after the calculations are ready. When I´m dont put the calculation in a seperate Thread then I can refresh or build my Image.

  • How can I see which shared folders my program has access to?

    - by Kasper Hansen
    My program needs to read and write to folders on other machines that might be in another domain. So I used the System.Runtime.InteropServices to add shared folders. This worked fine when it was hard coded in the main menu of my windows service. But since then something went wrong and I don't know if it is a coding error or configuration error. What is the scope of a shared folder? If a thread in my program adds a shared folder, can the entire local machine see it? Is there a way to view what shared folders has been added? Or is there a way to see when a folder is added? [DllImport("NetApi32.dll", SetLastError = true, CharSet = CharSet.Unicode)] internal static extern System.UInt32 NetUseAdd(string UncServerName, int Level, ref USE_INFO_2 Buf, out uint ParmError); [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)] internal struct USE_INFO_2 { internal LPWSTR ui2_local; internal LPWSTR ui2_remote; internal LPWSTR ui2_password; internal DWORD ui2_status; internal DWORD ui2_asg_type; internal DWORD ui2_refcount; internal DWORD ui2_usecount; internal LPWSTR ui2_username; internal LPWSTR ui2_domainname; } private void AddSharedFolder(string name, string domain, string username, string password) { if (name == null || domain == null || username == null || password == null) return; USE_INFO_2 useInfo = new USE_INFO_2(); useInfo.ui2_remote = name; useInfo.ui2_password = password; useInfo.ui2_asg_type = 0; //disk drive useInfo.ui2_usecount = 1; useInfo.ui2_username = username; useInfo.ui2_domainname = domain; uint paramErrorIndex; uint returnCode = NetUseAdd(String.Empty, 2, ref useInfo, out paramErrorIndex); if (returnCode != 0) { throw new Win32Exception((int)returnCode); } }

  • .Net C#: support differnt Office versions

    - by Chris
    We created an application that uses Office 2007 (Excel 2007) to read in data from an Excel worksheet. However. I noticed that when I want to deploy the application on a system with Office 2003 installed, it crashes because other PIA's (and other dll's) need to be referenced for this version of office. Do I need to compile different versions of my application to be able to support different versions of Office or is there a more ellegant solution for this problem? I use Visual Studio 2010 (C#) and the .Net 4.0 platform. Many thanks Chris

  • Why is the this-pointer needed to access inherited attributes?

    - by Shadow
    Hi, assume the following class is given: class Base{ public: Base() {} Base( const Base& b) : base_attr(b.base_attr) {} void someBaseFunction() { .... } protected: SomeType base_attr; }; When I want a class to inherit from this one and include a new attribute for the derived class, I would write: class Derived: public Base { public: Derived() {} Derived( const Derived& d ) : derived_attr(d.derived_attr) { this->base_attr = d.base_attr; } void SomeDerivedFunction() { .... } private: SomeOtherType derived_attr; }; This works for me (let's ignore eventually missing semicolons or such please). However, when I remove the "this-" in the copy constructor of the derived class, the compiler complains that "'base_attr' was not declared in this scope". I thought that, when inheriting from a class, the protected attributes would then also be accessible directly. I did not know that the "this-" pointer was needed. I am now confused if it is actually correct what I am doing there, especially the copy-constructor of the Derived-class. Because each Derived object is supposed to have a base_attr and a derived_attr and they obviously need to be initialized/set correctly. And because Derived is inheriting from Base, I don't want to explicitly include an attribute named "base_attr" in the Derived-class. IMHO doing so would generally destroy the idea behind inheritance, as everything would have to be defined again. EDIT Thank you all for the quick answers. I completely forgot the fact that the classes actually are templates. Please, see the new examples below, which are actually compiling when including "this-" and are failing when omiting "this-" in the copy-constructor of the Derived-class: Base-class: #include <iostream> template<class T> class Base{ public: Base() : base_attr(0) {} Base( const Base& b) : base_attr(b.base_attr) {} void baseIncrement() { ++base_attr; } void printAttr() { std::cout << "Base Attribute: " << base_attr << std::endl; } protected: T base_attr; }; Derived-class: #include "base.hpp" template< class T > class Derived: public Base<T>{ public: Derived() : derived_attr(1) {} Derived( const Derived& d) : derived_attr(d.derived_attr) { this->base_attr = d.base_attr; } void derivedIncrement() { ++derived_attr; } protected: T derived_attr; }; and for completeness also the main function: #include "derived.hpp" int main() { Derived<int> d; d.printAttr(); d.baseIncrement(); d.printAttr(); Derived<int> d2(d); d2.printAttr(); return 0; }; I am using g++-4.3.4. Although I understood now that it seems to come from the fact that I use template-class definitions, I did not quite understand what is causing the problem when using templates and why it works when not using templates. Could someone please further clarify this?

  • Drupal - how to register a MENU_CALLBACK that is accessable to all users(even anonymous ones)?

    - by rubayeet
    I'm trying to learn Drupal 6. I want to register the path '/topic' to a MENU_CALLBACK using hook_menu(). Here's what I have: function mymodule_menu() { $items = array() $items['foo'] = array( 'page callback' => 'show_page_foo', 'access callback' => 'user_access', 'access arguements' => array('access foo content'), 'type' => MENU_CALLBACK ); } function show_page_foo() { //show foo page } This works fine for a logged in user. But when I visit the path as an anonymous user it shows 'Access Denied' message. What must be the 'access callback' and 'access arguments' values to have this accessible to all visitors? I remember I made this work by simply saying 'access' => TRUE in Drupal 5. No longer works in Drupal 6.
