• SHFileOperation replace file dialog

  - by JHowzer

  Currently, SHFileOperation has some confirm file replacement dialog boxes that ask the user if they would like to replace a file or not. I find these useful, but I would like to be able to modify the scenario in which they occur. Instead, I would like to compare the file contents first with a bool compareFile() function I wrote. Then, if the files are identical the file replacement dialog box will not come up. Assuming, I already have a working compareFile() function, is there a way for me to do this? Thank you for your time.

• How can I update only certain fields in a Django model form?

  - by J. Frankenstein

  I have a model form that I use to update a model. class Turtle(models.Model): name = models.CharField(max_length=50, blank=False) description = models.TextField(blank=True) class TurtleForm(forms.ModelForm): class Meta: model = Turtle Sometimes I don't need to update the entire model, but only want to update one of the fields. So when I POST the form only has information for the description. When I do that the model never saves because it thinks that the name is being blanked out while my intent is that the name not change and just be used from the model. turtle_form = TurtleForm(request.POST, instance=object) if turtle_form.is_valid(): turtle_form.save() Is there any way to make this happen? Thanks!

• drawbacks of storing all ''things' in a central table

  - by naiquevin

  Hi, I am not sure if there is a term to describe this, but I have observed that content management systems store all kinds of data in a single table with their bare minimum properties while the meta data is stored in another table in form of key value pairs. for eg. everything (blog posts, pages, images, events etc) is stored in one table and considered as a post. I understand that this allows for abstraction and easy extensibility we are considering designing our new project this way. It is not exactly a CMS but we plan to keep adding modules to it in stages. Lets say initially there will be only posts and images on which comments can be posted. Later on we might add videos which will also have the commenting feature. what are the drawbacks of this approach ? and will it work for a requirement like ours ? Thanks

• Format table header

  - by Ryan Erb

  I have a table with slanted text in the header row, the only problem is that the text still makes the width of the columns way to large. Is there any way to squish together the table columns so that they are about the width of the select boxes? Or is there a way to place the text there without it in the header and maybe just use a <div> or <p>? Here is the fiddle I am working with: http://jsfiddle.net/t9Krg/1/ .slanted { -webkit-transform: rotate(-45deg); -moz-transform: rotate(-45deg); -ms-transform: rotate(-45deg); -o-transform: rotate(-45deg); transform: rotate(-45deg); white-space:nowrap; /* display:noblock; */ } The boarders around the header is just to see the extra spacing and will be removed later.

• Suggest Sphinx index scheme

  - by htf

  Hi. In a MySQL database I have documents of different type: some have text content, meta keys, descriptions, others have code, SKU number, size and brand name and so on. The problem is, I have to search something in all of these documents and then display a single page, where the results will be grouped by the document type, such as help page, blog post, item... It's not clear for me how to implement the Sphinx index: I want to have a single index to speed up queries, but since different docs have different structure - how can I group them? I was thinking about just concatenating them, but it just doesn't feel right.

• Is it possible to create a sub window which will not deactivate the parent?

  - by Bob

  Normally when creating a sub window (WS_POPUP), the child window will become activate and the parent will become deactivated. However, with menus, both remain active. At least I am assuming the menu is active, it at least has focus. Example: Click on the file menu in notepad, the menu appears, yet the notepad window still looks active. Is it possible to mirror this behavior with either a window style or responding to a particular message? Thanks Another example: Combo boxes seem to show a subwindow, yet do not deactivate the window. And you can click on that subwindow, while still maintaining an activate main window. Any ideas on how to grab the class /style of that window?

• CSS: Centering a floated block level element in IE6 (It almost works)

  - by Louis W

  I have a block level element which I am centering on the page. I have gotten it to work for all other browsers except IE6 where it ALMOST works. http://tinyurl.com/28sh9eq If I view the page in IE6 the red box is slightly off center of the pink one in IE. If I then resize the browser window it snaps into place where I want it. Uhhhhh.... yea.... what gives? How come resizing the window makes it work? I have also tried setting an explicit width on the wrapper with no avail. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"> <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta http-equiv="X-UA-Compatible" content="IE=7" /> <style type="text/css"> BODY { text-align: center; font-family: Arial; } .row_wrap { height: 100px; margin-bottom: 30px; background-color: pink; } .row { float: right; position: relative; left: -50%; text-align: left; clear: both; } .button1 { color: #FFF; height: 36px; text-decoration: none; position: relative; padding: 0 30px; background: url('button.gif') no-repeat 0 0; display: block; float: left; left: 50%; } .button1 .end { width: 20px; height: 37px; position: absolute; right: -2px; top: 0; background: url('button.gif') no-repeat right 0; } .button1 .text { font-size: 16px; font-weight: bold; white-space: nowrap; height: 36px; padding-top: 7px; display: block; float: left; } .button1 .text .arrow { vertical-align: 1px; } </style> </head> <body> <h2>RTL: Button 1</h2> <div class="row_wrap"> <div class="row" dir="rtl"> <a href="#" class="button1"> <span class="end"></span> <span class="text"><span class="arrow">»</span> Hello 1.</span> </a> </div> </div> <h2>RTL: Button 1-2</h2> <div class="row_wrap" style="width: 400px;"> <div class="row" dir="rtl"> <a href="#" class="button1"> <span class="end"></span> <span class="text"><span class="arrow">»</span> Hello 1.</span> </a> </div> </div> <br/><br/> <h2>Normal: Button 1</h2> <div class="row_wrap"> <div class="row"> <a href="#" class="button1"> <span class="end"></span> <span class="text"><span class="arrow">»</span> Hello.</span> </a> </div> </div> </body> Thanks for your help.

• WPF tooltip best practices

  - by Martin

  I'm about to change my application to include tool tips for all buttons, combo boxes, etc. I was wondering if there are any recommendations on doing this. For every control I'd like the tooltip to show the control's name in bold, followed by the description. I want to keep the style separated from the control, so I can change the tooltip style globally. What I would like to have, unless there's a better suggestion, is two additional fields per button/combobox/etc: 1-ToolTipName and 2-ToolTipDesc, both containing a string. How can I accomplish this (and is it even possible?).

• AppendTo, does it change the DOM?

  - by JD

  Hi, I have two list boxes and some JQuery function that does the following: $(document).ready(function () { //If you want to move selected item from fromListBox to toListBox $("#AddButton").click(function () { $("#fromListBox option:selected").appendTo("#toListBox"); }); }); I have a button that when clicked moves items from one list to another. This works, however when I do "View Page Source" in chrome, the list contains the original list and not the newly added items. I expected appendTo to change the DOM but clearly this is not what is happening. Why is this? JD

• JQuery multiple-choice quiz script: how to ensure the correct answer is available?

  - by DavidR

  I have a function. I pass to it an object with a list of questions and answers. I generate a random number from a range equal to the number of questions in the object. The script check to see if that question has been asked, and if not, it asks it, the correct answer is then passed to a variable correct. I want to give 4 possible answers, each one randomly selected from the list of possible answers. I have this. I just want to know what is the best way to ensure that the correct answer is placed in the list. So far, this is what I have: it puts four answers into four targeted boxes. I want to ensure that the correct answer is in a randomly selected box. function getRandom(limit) { return Math.floor(Math.random() * limit ) } $("#answers > .answer").each(function(i){ r = getRandom(total_questions); $(this).text(answers[r]) });

• RSS feed without items

  - by Jan Hancic

  I have webpage where I have a search page. I provide a "dynamic" RSS feed for search so that a user can subscribe to search results for any search term he likes. So I was wondering what is the standard (or best practise) way to do if that search term returns 0 results which means I have no "items" to put in the feed. Do I just return an empty feed (only including the meta data and no item elements). Or should I put some special item element in the feed with some "no results" text? edit: YouTube returns a feed without any item elements. If no-one can answer me I'll take it that this is the right way of doing it since I can't find any info elsewhere :)

• WebView with NSShadow slowdown

  - by Rodrigo

  I have a webview that shows some animated boxes, but it slows down and lags horribly when I put a drop shadow in the view. Without the shadow, the webview contents animate smoothly. I achieved a similar effect as safari/chrome when you do a elastic scroll with the touchpad. Looks nice! But doesnt run as smooth as in my inspirations. Here is the snippet of the shadow setting: NSShadow *dropShadow = [[NSShadow alloc] init]; [dropShadow setShadowColor:[NSColor blackColor]]; [dropShadow setShadowOffset:NSMakeSize(0, 0)]; [dropShadow setShadowBlurRadius:5.0]; [webview setWantsLayer: YES]; [webview setShadow: dropShadow]; [dropShadow release]; -- My question is: How can I work around this problem?

• Overlapping elements stop overlapping in IE7 on class change

  - by Gazzer

  On this page http://zenchan.com/program/ When I rollover the right box 2nd from the top suddenly the overlapping (negative margin disappears). What's happening is that a 'hover' class is being added to shift the background sprite. The two yellow boxes are debugging: if the hover class is put their in advance there is no problem. So fundamentally the CSS is not a problem for IE7 but adding the class is. Any ideas what's causing this. I've tried adding haslayout to various elements but to little effect.

• Maven: use dependencies from repository when running command line app ?

  - by Leonel

  Hi, I've used Maven to build my command line application. Now I'm going to distribute it as a jar file, and I need to handle the app's dependencies. I don't want to include all dependencies in the jar file as described here. The environment where my app will be run has Maven. I'd like Maven to run my jar looking at file META-INF/groupId/artifactId/pom.xml inside the package so it knows what the dependencies are and can find them in the repository. Any ideas ?

• Issue using Python to solve the Coin problem [closed]

  - by challarao

  I'm attempting to solve a problem commonly known as the Coin problem, but using McNuggets. McNuggets come in boxes containing either 6, 9, or 20 nuggets. I want to write a python script that uses Diophantine equations to determine if a given number of McNuggets n can be exactly purchased in these groupings. For example: 26 McNuggets -- Possible: 1 6-pack, 0 9-packs, 1 20-pack 27 McNuggets -- Possible: 0 6-packs, 3 9-packs, 0 20-packs 28 McNuggets -- Not possible This is my current attempt at writing the solution in Python, but the output is incorrect and I'm not sure what's wrong. n=input("Enter the no.of McNuggets:") a,b,c=0,0,0 count=0 for a in range(n): if 6*a+9*b+20*c==n: count=count+1 break else: for b in range(n): if 6*a+9*b+20*c==n: count=count+1 break else: for c in range(n): if 6*a+9*b+20*c==n: count=count+1 break if count>0: print "It is possible to buy exactly",n,"packs of McNuggetss",a,b,c else: print "It is not possible to buy"
