  • Create a rich text control field in VBA for Word 2010

    - by mkn
    I have a control field where I dynamically add certain text. That works well so far. The problem is that in one text I have an input field where the user can type in text. I need to hardcode the form text input field into the VBA code. How is this achieved? Or can someone point me in the right direction? In the following code snippet I need to replace the [InputField] by a VBA input field. ActiveDocument.SelectContentControlsByTitle("Bottom").Item(1).Range.Text = _ "Some Text" & vbNewLine & _ "Some Text" & vbNewLine & _ "Some Text" & vbNewLine & _ "Text [InputField] Text"

  • Create Java method from a string?

    - by drozzy
    Is it possible in Java, to declare a method with a string instead of an identifier? For example can I do something like the following: class Car{ new Method("getFoo", { return 1+1; }); } //Use it Car car = new Car(); car.getFoo(); EDIT: I am adding a Purpose WHY I need this. In order to not hardcode method names when using Jersey and it's UriBuilder, which requires a method name: https://jsr311.dev.java.net/nonav/releases/1.1/javax/ws/rs/core/UriBuilder.html See path() method with signature: public abstract UriBuilder path(java.lang.Class resource, java.lang.String method) throws java.lang.IllegalArgumentException I hope my question is clear, if not - let me know and I can clarify it.

  • how to create a SETUP.EXE wrapper for an MSI file using NSIS

    - by user222846
    I want to wrap a existing msi installer file into NSIS installer executable. Because there is not any option to change the icon of the msi file. I just want to customize the icon of the output setup.exe. Along with this I would also want to make sure that NSIS does not add any extra user interface into my installer. Have anybody an idea to do this ? Thanks in advance.

    - by Aakash Chakravarthy
    Hello, I am very much impressed by the "inset" like effect in many latest websites. Some examples are and The line in the center. Nowadays, many websites use these kinds of lines/effects. I tried to achieve the same with borders but the color combination is not working me and it is not proper. Do other websites use images for these ? is it easy to this ? Any example css ? Example sites: http://woothemes.com, http://net.tutsplus.com/ , http://www.w3schools.com (in the header) and in wordpress admin page sidebar

  • Create swipe controlled simple flipbook style animation in ObjC

    - by eco_bach
    Hi I am a beginner in Obj C development, though quite experienced (over 10 years) with other ECMAscript based languages and OOP development. I want to build a simple flipbook style animation, controlled through swiping motion. I'm sure extremely simple for any advanced ObjC coders. Can anyone with extensive ObjC-CocoaTouch experience give me some higher level recommendations? ie, 1 -general application design, should I start with a simple view based application, or navigation based or? 2 -should I use 3rd party animation frameworks such as Cocos2D, or stick with built in classes and methods? 3 -if using built in methods, classes, what is the recommended way of achieving a animation, that will be controlled via swipe and touch gestures? 4 -I want to eventually have multiple 'flipbooks' that I can 'instantly' swap with one another, ie to give the net effect of an object changing color, etc, but not sure how to approach this from a memory management point of view, related to #1 above Except for point 3 above, I'm not expecting any actual code examples. Just general guidelines to follow and perhaps, what are some next steps I should take in my goal as an ObjC code samurai.

  • Create a Color Picker, similar to Photoshop's, using Javascript and HTML Canvas

    - by André Alçada Padez
    I am not at all versed in Computer Graphics and am in need of creating a color picker as a javascript tool to embed in an HTML page. First, and looking at Photoshop's one, i thought of the RGB palette as a three-dimensional matrix. My first attempt envolved: <script type="text/javascript"> var rgCanvas = document.createElement('canvas'); rgCanvas.width = 256; rgCanvas.height = 256; rgCanvas.style.border = '3px solid black'; for (g = 0; g < 256; g++){ for (r = 0; r < 256; r++){ var context = rgCanvas.getContext('2d'); context.beginPath(); context.moveTo(r,g); context.strokeStyle = 'rgb(' + r + ', ' + g + ', 0)'; context.lineTo(r+1,g+1); context.stroke(); context.closePath(); } } var bCanvas = document.createElement('canvas'); bCanvas.width = 20; bCanvas.height = 256; bCanvas.style.border = '3px solid black'; for (b = 0; b < 256; b++){ var context = bCanvas.getContext('2d'); context.beginPath(); context.moveTo(0,b); context.strokeStyle = 'rgb(' + 0 + ', ' + 0 + ', ' + b + ')'; context.lineTo(20, b); context.stroke(); context.closePath(); } document.body.appendChild(rgCanvas); document.body.appendChild(bCanvas); </script> this results in something like My thought is this is too linear, comparing to the ones i see in Photoshop and on the web. I would like to know the logic behind the color mapping in a picker like this: I don't really need the algorythms itself, i'm mainly trying to understand the logic. Thanks

  • how to create a mootools 1.1 function with array

    - by liz
    i have a series of select lists, that i am using to populate text boxes with ids. so you click a select option and another text box is filled with its id. with just one select/id pair this works fine, but i have multiples, and the only thing that changes is the id of the select and input.. in fact just the ending changes, the inputs all start with featredproductid and the select ids all start with recipesproduct and then both end with the category. i know that listing this over and over for each category is not the way to do it. i think i need to make an array of the categories var cats = ['olive oil', "grains", "pasta"] and then use a forEach function? maybe? here is the clunky code window.addEvent('domready', function() { $('recipesproductoliveoil').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidoliveoil").setProperties({ value: pidselected}); ; }); $('recipesproductgrains').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidgrains").setProperties({ value: pidselected}); ; }); $('recipesproductpasta').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidpasta").setProperties({ value: pidselected}); ; }); $('recipesproductpantry').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidpantry").setProperties({ value: pidselected}); ; }); }); keep in mind this is mootools 1.1 (no i cant update it sorry). i am sure this is kind of basic, something i seem to have wrapping my brain around. but i am quite sure doing it as above is not really good...

  • How do I create a hyperlink in java?

    - by Justin984
    I'm going through the google app engine tutorials at https://developers.google.com/appengine/docs/java/gettingstarted/usingusers I'm very new to google app engine, java and web programming in general. So my question is, at the bottom of the page it says to add a link to allow the user to log out. So far I've got this: public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { UserService userService = UserServiceFactory.getUserService(); User user = userService.getCurrentUser(); if(user != null){ resp.setContentType("text/plain"); resp.getWriter().println("Hello, " + user.getNickname()); String logoutLink = String.format("<a href=\"%s\">Click here to log out.</a>", userService.createLogoutURL(req.getRequestURI())); resp.getWriter().println(logoutLink); }else { resp.sendRedirect(userService.createLoginURL(req.getRequestURI())); } } However instead of a link, the full string is printed to the screen including the tags. When I look at the page source, I have no tags or any of the other stuff that goes with a webpage. I guess that makes sense considering I've done nothing to output any of that. Do I just do a bunch of resp.GetWriter().println() statements to output the rest of the webpage, or is there something else I don't know about? Thanks!

  • Duplicate an AppEngine Query object to create variations of a filter without affecting the base quer

    - by Steve Mayne
    In my AppEngine project I have a need to use a certain filter as a base then apply various different extra filters to the end, retrieving the different result sets separately. e.g.: base_query = MyModel.all().filter('mainfilter', 123) Then I need to use the results of various sub queries separately: subquery1 = basequery.filter('subfilter1', 'xyz') #Do something with subquery1 results here subquery2 = basequery.filter('subfilter2', 'abc') #Do something with subquery2 results here Unfortunately 'filter()' affects the state of the basequery Query instance, rather than just returning a modified version. Is there any way to duplicate the Query object and use it as a base? Is there perhaps a standard Python way of duping an object that could be used? The extra filters are actually applied by the results of different forms dynamically within a wizard, and they use the 'running total' of the query in their branch to assess whether to ask further questions. Obviously I could pass around a rudimentary stack of filter criteria, but I'd rather use the Query itself if possible, as it adds simplicity and elegance to the solution.

  • PHP Scale image and then create image of specific size

    - by Ronny vdb
    The result I am trying to achieve is that the user can upload an image of any size, and the server side script will convert it to an image that has the dimension 1024x512. To save the aspect ratio of the image I first scale the image down by either the width or height to match the wanted dimensions. to do this I am using imagecopyresampled(): imagecopyresampled( $new_img, $src_img, $dst_x, $dst_y, 0, 0, $new_width, $new_height, $img_width, $img_height ) && $write_image($new_img, $new_file_path, $image_quality); If we take an image that is 1920x1200 as an example, the outputted image will be 819x512. However I still need a final result of 1024x512 so I want to add white borders to the image to will the width to 1024. How can I correct my imagecopyresampled function to acheive this?

  • How to create a string array in matlab?

    - by aduric
    I would like to pass a vector of strings from C++ to matlab. I have tried using the functions available such as mxCreateCharMatrixFromStrings but it doesn't give me the correct behavior. So, I have something like this: void mexFunction( int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[]) { vector<string> stringVector; stringVector.push_back("string 1"); stringVector.push_back("string 2"); //etc... The problem is how do I get this vector to the matlab environment? plhs[0] = ??? My goal is to be able to run: >> [strings] = MyFunc(...) >> strings(1) = 'string 1'

  • Is it OK to re-create many SQL connections (SQL 2008)

    - by Mr. Flibble
    When performing many inserts into a database I would usually have code like this: using (var connection = new SqlConnection(connStr)) { connection.Open(); foreach (var item in items) { var cmd = new SqlCommand("INSERT ...") cmd.ExecuteNonQuery(); } } I now want to shard the database and therefore need to choose the connection string based on the item being inserted. This would make my code run more like this foreach (var item in items) { connStr = GetConnectionString(item); using (var connection = new SqlConnection(connStr)) { connection.Open(); var cmd = new SqlCommand("INSERT ...") cmd.ExecuteNonQuery(); } } Which basically means it's creating a new connection to the database for each item. Will this work or will recreating connections for each insert cause terrible overhead?
