  • Secure messaging using Signed MIME is it reliable?

    - by aaronb
    We have an automatic reporting and notification system written in .net that sends emails with plain text. We are having to encrypt the messages that we send our clients. The possible implementation approaches we have: Send messages as S/Mime email with attachments. Plain text email with that just contains a link to a web site that will display the message over https. It seems like S/Mime is a simpler solution, as we won't need to create the web application or secure it. Our concern is our interoperability with our clients email clients and more importantly their email filtering software. Has anyone had success or issues deploying a Signed MIME messaging solution?

  • C# - High Quality Byte Array Conversion of Images

    - by Lijo
    Hi Team, I am converting images to byte array and storing in a text file using the following code. I am retrieving them successfully as well. My concern is that the quality of the retrieved image is not up to the expectation. Is there a way to have better conversion to byte array and retrieving? I am not worried about the space conception. Please share your thoughts. string plaintextStoringLocation = @"D:\ImageSource\Cha5.txt"; string bmpSourceLocation = @"D:\ImageSource\Cha50.bmp"; ////Read image Image sourceImg = Image.FromFile(bmpSourceLocation); ////Convert to Byte[] byte[] clearByteArray = ImageToByteArray(sourceImg); ////Store it for future use (in plain text form) StoreToLocation(clearByteArray, plaintextStoringLocation); //Read from binary byte[] retirevedImageBytes = ReadByteArrayFromFile(plaintextStoringLocation); //Retrieve from Byte[] Image destinationImg = ByteArrayToImage(retirevedImageBytes); //Display Image pictureBox1.Image = destinationImg; Thanks Lijo

  • WPF MVVM: How do ViewModels communicate with each other?

    - by Dev1
    I have a View which has 2 sub views on it and a ViewModel is assigned to each view: ViewA - ViewModelA { ViewB - ViewModelB ViewC - ViewModelC } ViewB has a text box and ViewC has a combobox, both of which i need access from ViewModelA. Not the GUI control itself, but the bound value i.e. .Text of the textbox and .SelectedItem of the ComboBox. Currently i just have ViewModelB and ViewModelC as properties on ViewModelA but it feels wrong. What's the standard way for view models to communicate with each other without breaking the MVVM pattern? I'm completely new to WPF/MVVM.

  • SWF (using XML) only working locally, not on home server or web hosting server

    - by Andy
    Hi, I use a main SWF file, which has some animations. It uses xml from a .php file which specifies several items, e.g. images and other SWFs to be used in the main SWF. Locally everything works perfectly, but when invoking it via my home server, or hosting provider it doesn't work anymore and I don't get why. All links are relative and correct. Somehow the main SWF doesn't load fully, or has problems with the XML from the .php file. I'm not sure, now I only get a black box that doesn't show any of the other content it's supposed to. check it out: http://deoshermes.ath.cx/cc-common/templates/dynamiclead/dynamic_leadee.swf the XML: <?xml version="1.0" ?><dynamic_content> <item blurb="Text 1" content_url="" content_source="" content_timer="8000" content_target="_self" tab_color="0x000000" tab_border_color="0x000000" tab_arrow_color="0xFFFFFF" tab_text_color="0xFFFFFF" tab_image="/template/images/dle_TOPmay06.jpg" cycle="true" content_border_color="0x" content_bg_image="" tab_hl_color="0x000000" tab_highlight_color="0x" tab_highlight_text_color="0x" tab_highlight_image="" > </item> <item blurb="Text 2" content_timer="5000" cycle="true" content_border_color="0x" content_bg_image="" tab_hl_color="0xFFFFFF" tab_border_color="0xFFFFFF" tab_color="0xFFFFFF" tab_arrow_color="0xFFFFFF" tab_text_color="0xFFFFFF" tab_image="/template/images/dle_MIDandBOTmay06.jpg" tab_highlight_color="0x" tab_highlight_text_color="0x" tab_highlight_image="" content_url="" content_source="" content_target="_self" > </item> <item blurb="Text 3" content_timer="5000" cycle="true" content_border_color="0x" content_bg_image="" tab_hl_color="0xFFFFFF" tab_border_color="0xFFFFFF" tab_color="0xFFFFFF" tab_arrow_color="0xFFFFFF" tab_text_color="0xFFFFFF" tab_image="/template/images/dle_MIDandBOTmay06.jpg" tab_highlight_color="0x" tab_highlight_text_color="0x" tab_highlight_image="" content_url="" content_source="" content_target="_self" > </item> </dynamic_content> this works like a charm when invoking the main SWF locally. The ActionScript from the main sWF can be found at samedomain as above/Actionscript_mainmovie.txt This also seems to work great. the function formattabs (line 68) uses some javascript. Locally the main SWF functions even without this hbx file which is located /cc-common/wss/hbx.js and use in the webpage actually. I haven't got a clue what's keeping the main SWF from working properly, because all other single SWFs work properly when invoked using a direct link. And this one just isn't working... Do I maybe need to add something in the php.ini file?? Any help would be appreciated!

  • A depth (z-index) nightmare.

    - by JCOC611
    The best way to illustrate this question is with...a Fiddle! Before you visit the fiddle, notice there is text behind the grayest element, which is on top of a light gray element that has a border. There is a main wrapping div (root), and two wrapping divs inside (wrap1 and wrap2). The problem here is that I need the content of wrap2 (highlight) to be behind the content of wrap1 (text), but in front of the background of the root. This, however, must not change: The HTML, the elements and wraps should be left untouched. Excluding the order of wrap1 and wrap2 inside root. The highlight div must keep the absolute positioning. Styling highlight with background-color is not an option, the existence of highlight is a must. PS: the italics reference the id's of <div>s in the fiddle example, for whomever was too lazy to visit it.

  • Getting data into an input field from YUI Calendar with multi-select:true

    - by kylex
    <script type="text/javascript"> YAHOO.util.Event.onDOMReady(function(){ YAHOO.dateSelects.exc = new YAHOO.widget.Calendar("exc","excContainer", { title:"Choose a date:", close:true, multi_select:true }); YAHOO.dateSelects.exc.render(); YAHOO.util.Event.addListener( "excshowup", "click", YAHOO.dateSelects.exc.show, YAHOO.dateSelects.exc, true ); }); </script> <div class="calendarOuterContainer"> <div id="excContainer" class="calendarContainer"></div> </div> <a id="excshowup"><img src="/images/icons/calendar.png" /></a> The preceding code generates a YUI calendar with the ability to select multiple dates on one calendar. What I am having trouble figuring out is how to capture that data and place it inside a text input tag on the fly. So when a person clicks the close button, all the selected dates are populated inside the input tag. Suggestions?

  • How do I make a GUI that behaves like this?

    - by Karl Knechtel
    This is difficult to explain without illustration, so - behold, an illustration, cobbled together from screenshots of a few hello-world examples and a lot of Paint work: I have started out using Windows Forms on .NET (via IronPython, but that shouldn't be important), and haven't been able to figure out very much. GUI libraries in general are very intimidating, simply because every class has so many possible attributes. Documentation is good at explaining what everything does, but not so good at helping you figure out what you need. I will be assembling the GUI dynamically, but I'm not expecting that to be the hard part. The sticking points for me right now are: How do I get text labels to size themselves automatically to the width of the contained text (so that the text doesn't clip, and I also don't reserve unnecessary space for them when resizing the window)? How do I make the vertical scrollbar always appear? Setting the VScroll property (why is this protected when AutoScroll is public, BTW?) doesn't seem to do anything. How come the horizontal scrollbar is not added by AutoScroll when contents are laid out vertically (via Dock = DockStyle.Top)? I can use a minimum size for panels to prevent the label and corresponding control from overlapping when the window is shrunk horizontally, but then the scrollbar doesn't appear and the control is inaccessible. How can I put limits on window resizing (e.g. set a minimum width) without disabling it completely? (Just set minimum/maximum sizes for the Form?) Related to that, is there any way to set minimum/maximum widths or heights without setting a minimum/maximum size (i.e. can I constrain the size in only one dimension)? Is there a built-in control suitable for hex editing or am I going to have to build something myself? ... And should I be using something else (perhaps something more capable?) I've heard WPF mentioned, but I understand that this involves XML and I really want to build a GUI from XML - I already have data in an object graph, and doing some kind of weird XML pseudo-serialization (in Python, no less!) in order to create a GUI seems incredibly roundabout.

  • Syntax Highlighting in a ListBox

    - by ph0enix
    Hi all, I've searched the web and I can't seem to find anything that will work for me. I've seen plenty of discussion, and even some fairly extensible open-source tools, for code editors that provide line numbers and syntax highlighting. Here's my dilemma... I'm working on a "digital code review" project in C#.NET that allows users to specify source files, add them to a particular session, and other users can make comments and line references to the files being reviewed. Basic requirements: Must be written in C#.NET I don't need to be able to edit the text in the text box Users need to be able to select a line (or multiple lines), to make line references. It seems to me that I need some fancy implementation of a ListBox control (not a drop-down list) that has some OwnerDraw capabilities to add line numbers and syntax highlighting. Unfortunately, I haven't had any luck putting it together myself, and I can't seem to find a control that's already been written or a reference on how I might be able to accomplish this. Any suggestions??

  • how do i extract the last value of every output in c# ?

  • How to add Transparency information to a HEX color code?

    - by TK123
    I have to modify some code and the previous developer left this comment: color: color, // e.g. '#RRGGBBFF' - Last 2 digits are alpha information On the page there is a color picker that let's the user change text color. It gives HEX values like so: #RRGGBB And there is a slider that allows the user to change a text's transparency. It runs from 0.1 to 1 Somehow I need to get a 2 digit letter from this transparency amount and append it to the HEX value for it to work. Does anyone know how to append Alpga information to HEX color codes? What is the math formula for it? I guess the question can also be answered if anyone knows how to concert RGBA color values with transparency into HEX: rgba(255, 255, 255, 0.6)

  • How to use jQuery to generate 2 new associated objects in a nested form?

    - by mind.blank
    I have a model called Pair, which has_many :questions, and each Question has_one :answer. I've been following this railscast on creating nested forms, however I want to generate both a Question field and it's Answer field when clicking on an "Add Question" link. After following the railscast this is what I have: ..javascripts/common.js.coffee: window.remove_fields = (link)-> $(link).closest(".question_remove").remove() window.add_fields = (link, association, content)-> new_id = new Date().getTime() regexp = new RegExp("new_" + association, "g") $(link).before(content.replace(regexp, new_id)) application_helper.rb: def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.simple_fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, "window.add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")", class: "btn btn-inverse") end views/pairs/_form.html.erb: <%= simple_form_for(@pair) do |f| %> <div class="row"> <div class="well span4"> <%= f.input :sys_heading, label: "System Heading", placeholder: "required", input_html: { class: "span4" } %> <%= f.input :heading, label: "User Heading", input_html: { class: "span4" } %> <%= f.input :instructions, as: :text, input_html: { class: "span4 input_text" } %> </div> </div> <%= f.simple_fields_for :questions do |builder| %> <%= render 'question_fields', f: builder %> <% end %> <%= link_to_add_fields "<i class='icon-plus icon-white'></i> Add Another Question".html_safe, f, :questions %> <%= f.button :submit, "Save Pair", class: "btn btn-success" %> <% end %> _question_fields.html.erb partial: <div class="question_remove"> <div class="row"> <div class="well span4"> <%= f.input :text, label: "Question", input_html: { class: "span4" }, placeholder: "your question...?" %> <%= f.simple_fields_for :answer do |builder| %> <%= render 'answer_fields', f: builder %> <% end %> </div> </div> </div> _answer_fields.html.erb partial: <%= f.input :text, label: "Answer", input_html: { class: "span4" }, placeholder: "your answer" %> <%= link_to_function "remove", "remove_fields(this)", class: "float-right" %> I'm especially confused by the reflect_on_association part, for example how does calling .new there create an association? I usually need to use .build Also for a has_one I use .build_answer rather than answers.build - so what does this mean for the jQuery part?

  • Highlighting a radio button with CSS

    - by dsoftware
    I have been trying to highlight a radio button with CSS but have been unsuccessful to get styling to work in FireFox. I see some methods of using images to render highlighting.

Example <input type="text" style="border-color:#FF0000"> <input type="radio" style="border-color:#FF0000"> The text box will have a border that is red but the radio button will not take the border color?

  • jQuery UI problem: why do the elements go flying around the screen?

    - by George Edison
    Yes, I know the title sounds a little suspicious. I will try to explain this the best I can... The code below is supposed to have the blue div slide down beside the red div. The first time you hit the Show the div button, it works. Also, the Hide the div works. Then when I click to show the div again, it appears to the right of where it is supposed to be! Why is this?!?
