• MVC Partial View to Call Display Pop-up window using jquery

  - by Gavin campbell

  Hi I have a index page the renders objects from my database as a treeview, each item has a link href="/MessageGroupType/Edit/1002 that makes an Ajax call to display a partial view in a DIV. Within the partial view there is a delete button which calls my controller to delete the item. However, i do a check to make sure the item can be deleted, if the item cant be deleted then i wish a pop-up to appear back on the edit form telling the user they cant delete this record. In my Edit partial view i have the following code " type="text/javascript" $(function() { $("#dialog").dialog(); }); <% if (Boolean.Parse(ViewData["DisplayWindow"].ToString())){% This Mesage group Type Cannot be deleted as is linked to other message group Types <% }% So my main questions are Can i make a reference to a javascript script within my Partial View (i dont want my master page to be called on the partial view) When i dynamically load the partial view data into my DIV - can i then after calling my controller insert another DIV into the first DIV. I am i doing this the wrong way - so any pointers is appreciated Cheers

• C# Showing Form with WS_EX_NOACTIVATE flag

  - by Maks

  I have a borderless form which is always on top and with WS_EX_NOACTIVATE flag set to prevent it for gaining focus. const int WS_EX_NOACTIVATE = 0x08000000; protected override CreateParams CreateParams { get { CreateParams param = base.CreateParams; param.ExStyle |= WS_EX_NOACTIVATE; return param; } } Form contains small picture box for moving (since it's borderless): private void pictureBox4_MouseMove(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { ReleaseCapture(); SendMessage(this.Handle, 0xa1, 0x2, 0); } } However when I move the window it doesn't get redrawn/shown, only when I release the mouse button it moves form to that location. I saw some application which are are working in a similar fashion but they are showing the window while moving (like some virtual keyboards I saw) and also many questions on net about this issue but no answer. Can someone please tell me is it possible to show window/form like this while moving (like "normal" window) and if yes, how to do it? Thanks.

• dequeueReusableCell:withIdentifier: returns a cell even if it is not there?

  - by lostInTransit

  Hi I am using SDK 3.2 to create an iPad application. In my table I have 2 kinds of rows, one with a custom accessory view and another without any. I use two different cell identifiers for creating these. The first cell is created properly (dequeueReusable... returns a nil and the cell is initialized). But when a call is made to dequeueReusable.. with the other cell identifier, the cell is not nil (it should be because this is the first time the identifier is being used) An even stranger part is that when I use this cell to set the textLabel's text, it returns an EXC_BAD_ACCESS. So 2 questions Why is dequeueReusable... returning a cell when there is no cell created using the said identifier Even if it does return a cell, why is access to textLabel causing a crash? Thanks.

• Windows 7 64 / Visual Studio 2008 / OpenCV2.1 error: "The application was unable to start correctly

  - by James

  Hey all, I'm building OpenCV2.1 from top of branch in 64 bit mode, when I link the libraries against my code (that works in 32 bit mode on XP), I get the dialog: "The application was unable to start correctly (0xc0150002) Click OK to close the application" When I start the application. The event viewer is pointing at one of the OpenCV dll's & says it's a Side-by-Side error, but I'm definitely building OpenCV & my code as a 64 bit compile, and there are no errors during that process. I've tried fiddling with the /MTd options & it doesn't help. Some (almost) related questions have suggested installing the VS2008 redistributable package, but I'm building using vs2008 pro, that seems like madness? Is it still necessary to install the package in my case? Any help, including the cause of these side-by-side errors, would be appreciated. James

• C# Open Source/Free Social Networking SDK

  - by Nix

  I am currently gathering some technology requirements for a site that will be a social network based. I don't want to re-invent the wheel so i am looking for some type of SDK or collection of tools that can provide me with a way of creating/managing a social network. I understand that no framework will probably fit my exact needs so I am also looking for a flexible/extendable framework. An example extension point would be allowing the user to provide sub networks, maybe a global network that could be sub classified as work and friends. Beyond that it would also be nice to somehow be able to import contacts from other networking sites (Facebook, Linked In, etc). My current technology suite will more than likely consist of the following: IIS 7.0 WCF Data Services SQL Server 2006 ASP.NET front end. So my two questions are 1) C# Open Source Social Network SDK 2) C# Open Source Social Netowrk APIs (facebook, linked in, etc) If there is any more information you may need please let me know.

• Creating blob properties with Entity Framework 4?

  - by David Veeneman

  I am creating an EF4 model-first application with a WPF UI. One of the controls on my UI is a RichTextDocument, which outputs a WPF FlowDocument. I can either serialize the FlowDocument to a byte array, or extract its XAML markup as a string. I would prefer to use binary serialization, if I can. Here are my questions: If I serialize to a byte array, how do I specify an entity property as a byte array in the EDM Designer? If I extract a XAML markup string, can I specify that the EDM Designer create the corresponding database column as a nvarchar(max) column? As to the second question, I assume I could always manually edit the MyModel.edmx.sql file to change the data type from nvarchar(4000) to nvarchar(max) before executing it, but I would like to know if it can be done in the Designer. Thanks for your help.

• Android: Haptic feedback: onClick() event vs hapticFeedbackEnabled in the view

  - by dreeves

  If you want a button to provide haptic feedback (ie, the phone vibrates very briefly so you can feel that you really pushed the button), what's the standard way to do that? It seems you can either explicitly set an onClick() event and call the vibrate() function, giving a number of milliseconds to vibrate, or you can set hapticFeedbackEnabled in the view. The documentation seems to indicate that the latter only works for long-presses or virtual on-screen keys: http://developer.android.com/reference/android/view/View.html#performHapticFeedback(int) If that's right, then I need to either make my button a virtual on-screen key or manually set the onClick() event. What do you recommend? Also, if I want the vibrating to happen immediately when the user's finger touches the button, as opposed to when their finger "releases" the button, what's the best way to accomplish that? Related question: http://stackoverflow.com/questions/2228151/how-to-enable-haptic-feedback-on-button-view

• IE8 Fixed Header, scrollable GridView

  - by Nix

  I know this topic has been asked, but the posts are all out of date, or not functional on IE8. In brief we basically want to do the excel style locking of column headers in a GridView. I have seen a couple of solutions one jquery+ css(setExpression) which doesn't work in IE8. And another that uses ajax extensions, yet again doesn't work in IE8. I have been through every solution in the below link and have yet to find a working implementation for IE8. http://stackoverflow.com/questions/2205271/gridview-how-to-make-fixed-header-row I see telerik has an implementation that is more thank what i want, this is such a simple concept I can believe i am going to have to buy a toolkit...

• Ask How-To Geek: Learning the Office Ribbon, Booting to USB with an Old BIOS, and Snapping Windows

  - by Jason Fitzpatrick

  You’ve got questions and we’ve got answers. Today we highlight how to master the new Office interface, USB boot a computer with outdated BIOS, and snap windows to preset locations. Learning the New Office Ribbon Dear How-To Geek, I feel silly asking this (in light of how long the new Office interface has been out) but my company finally got around to upgrading from Windows XP and Office 2000 so the new interface it totally new to me. Can you recommend any resources for quickly learning the Office ribbon and the new changes? I feel completely lost after two decades of the old Office interface. Help! Sincerely, Where the Hell is Everything? Dear Where the Hell, We think most people were with you at some point in the last few years. “Where the hell is…” could possibly be the slogan for the new ribbon interface. You could browse through some of the dry tutorials online or even get a weighty book on the topic but the best way to learn something new is to get hands on. Ribbon Hero turns learning the new Office features and ribbon layout into a game. It’s no vigorous round of Team Fortress mind you, but it’s significantly more fun than reading a training document. Check out how to install and configure Ribbon Hero here. You’ll be teaching your coworkers new tricks in no time. Boot via USB with an Old BIOS Dear How-To Geek, I’m trying to repurpose some old computers by updating them with lightweight Linux distros but the BIOS on most of the machines is ancient and creaky. How ancient? It doesn’t even support booting from a USB device! I have a large flash drive that I’ve turned into a master installation tool for jobs like this but I can’t use it. The computers in question have USB ports; they just aren’t recognized during the boot process. What can I do? USB Bootin’ in Boise Dear USB Bootin’, It’s great you’re working to breathe life into old hardware! You’ve run into one of the limitations of older BIOSes, USB was around but nobody was thinking about booting off of it. Fortunately if you have a computer old enough to have that kind of BIOS it’s likely to also has a floppy drive or a CDROM drive. While you could make a bootable CDROM for your application we understand that you want to keep using the master USB installer you’ve made. In light of that we recommend PLoP Boot Manager. Think of it like a boot manager for your boot manager. Using it you can create a bootable floppy or CDROM that will enable USB booting of your master USB drive. Make a CD and a floppy version and you’ll have everything in your toolkit you need for future computer refurbishing projects. Read up on creating bootable media with PLoP Boot Manager here. Snapping Windows to Preset Coordinates Dear How-To Geek, Once upon a time I had a company laptop that came with a little utility that snapped windows to preset areas of the screen. This was long before the snap-to-side features in Windows 7. You could essentially configure your screen into a grid pattern of your choosing and then windows would neatly snap into those grids. I have no idea what it was called or if was anymore than a gimmick from the computer manufacturer, but I’d really like to have it on my new computer! Bend and Snap in San Francisco, Dear Bend and Snap, If we had to guess, we’d guess your company must have had a set of laptops from Acer as the program you’re describing sounds exactly like Acer GridVista. Fortunately for you the application was extremely popular and Acer released it independently of their hardware. If, by chance, you’ve since upgraded to a multiple monitor setup the app even supports multiple monitors—many of the configurations are handy for arranging IM windows and other auxiliary communication tools. Check out our guide to installing and configuring Acer GridVista here for more information. Have a question you want to put before the How-To Geek staff?

• SQLite, python, unicode, and non-utf data

  - by Nathan Spears

  I started by trying to store strings in sqlite using python, and got the message: sqlite3.ProgrammingError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings. Ok, I switched to Unicode strings. Then I started getting the message: sqlite3.OperationalError: Could not decode to UTF-8 column 'tag_artist' with text 'Sigur Rós' when trying to retrieve data from the db. More research and I started encoding it in utf8, but then 'Sigur Rós' starts looking like 'Sigur Rós' note: My console was set to display in 'latin_1' as @John Machin pointed out. What gives? After reading this, describing exactly the same situation I'm in, it seems as if the advice is to ignore the other advice and use 8-bit bytestrings after all. I didn't know much about unicode and utf before I started this process. I've learned quite a bit in the last couple hours, but I'm still ignorant of whether there is a way to correctly convert 'ó' from latin-1 to utf-8 and not mangle it. If there isn't, why would sqlite 'highly recommend' I switch my application to unicode strings? I'm going to update this question with a summary and some example code of everything I've learned in the last 24 hours so that someone in my shoes can have an easy(er) guide. If the information I post is wrong or misleading in any way please tell me and I'll update, or one of you senior guys can update. Summary of answers Let me first state the goal as I understand it. The goal in processing various encodings, if you are trying to convert between them, is to understand what your source encoding is, then convert it to unicode using that source encoding, then convert it to your desired encoding. Unicode is a base and encodings are mappings of subsets of that base. utf_8 has room for every character in unicode, but because they aren't in the same place as, for instance, latin_1, a string encoded in utf_8 and sent to a latin_1 console will not look the way you expect. In python the process of getting to unicode and into another encoding looks like: str.decode('source_encoding').encode('desired_encoding') or if the str is already in unicode str.encode('desired_encoding') For sqlite I didn't actually want to encode it again, I wanted to decode it and leave it in unicode format. Here are four things you might need to be aware of as you try to work with unicode and encodings in python. The encoding of the string you want to work with, and the encoding you want to get it to. The system encoding. The console encoding. The encoding of the source file Elaboration: (1) When you read a string from a source, it must have some encoding, like latin_1 or utf_8. In my case, I'm getting strings from filenames, so unfortunately, I could be getting any kind of encoding. Windows XP uses UCS-2 (a Unicode system) as its native string type, which seems like cheating to me. Fortunately for me, the characters in most filenames are not going to be made up of more than one source encoding type, and I think all of mine were either completely latin_1, completely utf_8, or just plain ascii (which is a subset of both of those). So I just read them and decoded them as if they were still in latin_1 or utf_8. It's possible, though, that you could have latin_1 and utf_8 and whatever other characters mixed together in a filename on Windows. Sometimes those characters can show up as boxes, other times they just look mangled, and other times they look correct (accented characters and whatnot). Moving on. (2) Python has a default system encoding that gets set when python starts and can't be changed during runtime. See here for details. Dirty summary ... well here's the file I added: \# sitecustomize.py \# this file can be anywhere in your Python path, \# but it usually goes in ${pythondir}/lib/site-packages/ import sys sys.setdefaultencoding('utf_8') This system encoding is the one that gets used when you use the unicode("str") function without any other encoding parameters. To say that another way, python tries to decode "str" to unicode based on the default system encoding. (3) If you're using IDLE or the command-line python, I think that your console will display according to the default system encoding. I am using pydev with eclipse for some reason, so I had to go into my project settings, edit the launch configuration properties of my test script, go to the Common tab, and change the console from latin-1 to utf-8 so that I could visually confirm what I was doing was working. (4) If you want to have some test strings, eg test_str = "ó" in your source code, then you will have to tell python what kind of encoding you are using in that file. (FYI: when I mistyped an encoding I had to ctrl-Z because my file became unreadable.) This is easily accomplished by putting a line like so at the top of your source code file: # -*- coding: utf_8 -*- If you don't have this information, python attempts to parse your code as ascii by default, and so: SyntaxError: Non-ASCII character '\xf3' in file _redacted_ on line 81, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details Once your program is working correctly, or, if you aren't using python's console or any other console to look at output, then you will probably really only care about #1 on the list. System default and console encoding are not that important unless you need to look at output and/or you are using the builtin unicode() function (without any encoding parameters) instead of the string.decode() function. I wrote a demo function I will paste into the bottom of this gigantic mess that I hope correctly demonstrates the items in my list. Here is some of the output when I run the character 'ó' through the demo function, showing how various methods react to the character as input. My system encoding and console output are both set to utf_8 for this run: '?' = original char <type 'str'> repr(char)='\xf3' '?' = unicode(char) ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data 'ó' = char.decode('latin_1') <type 'unicode'> repr(char.decode('latin_1'))=u'\xf3' '?' = char.decode('utf_8') ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data Now I will change the system and console encoding to latin_1, and I get this output for the same input: 'ó' = original char <type 'str'> repr(char)='\xf3' 'ó' = unicode(char) <type 'unicode'> repr(unicode(char))=u'\xf3' 'ó' = char.decode('latin_1') <type 'unicode'> repr(char.decode('latin_1'))=u'\xf3' '?' = char.decode('utf_8') ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data Notice that the 'original' character displays correctly and the builtin unicode() function works now. Now I change my console output back to utf_8. '?' = original char <type 'str'> repr(char)='\xf3' '?' = unicode(char) <type 'unicode'> repr(unicode(char))=u'\xf3' '?' = char.decode('latin_1') <type 'unicode'> repr(char.decode('latin_1'))=u'\xf3' '?' = char.decode('utf_8') ERROR: 'utf8' codec can't decode byte 0xf3 in position 0: unexpected end of data Here everything still works the same as last time but the console can't display the output correctly. Etc. The function below also displays more information that this and hopefully would help someone figure out where the gap in their understanding is. I know all this information is in other places and more thoroughly dealt with there, but I hope that this would be a good kickoff point for someone trying to get coding with python and/or sqlite. Ideas are great but sometimes source code can save you a day or two of trying to figure out what functions do what. Disclaimers: I'm no encoding expert, I put this together to help my own understanding. I kept building on it when I should have probably started passing functions as arguments to avoid so much redundant code, so if I can I'll make it more concise. Also, utf_8 and latin_1 are by no means the only encoding schemes, they are just the two I was playing around with because I think they handle everything I need. Add your own encoding schemes to the demo function and test your own input. One more thing: there are apparently crazy application developers making life difficult in Windows. #!/usr/bin/env python # -*- coding: utf_8 -*- import os import sys def encodingDemo(str): validStrings = () try: print "str =",str,"{0} repr(str) = {1}".format(type(str), repr(str)) validStrings += ((str,""),) except UnicodeEncodeError as ude: print "Couldn't print the str itself because the console is set to an encoding that doesn't understand some character in the string.

• TTThumbsViewController + navigationController issue

  - by michael

  Hi, .. 2 questions. I am only using Three20 for a gallery in my app. When I push my .. : TTThumbsViewController from another view, the navigation bar is not the color I want it to be (as per the rest of my app). I have set up a TTDefaultStyleSheet as per this stackoverflow QA. Is there something special I have to do as I am only using the TTThumbsViewController? The thumbs view is also created with extra space at the top, as though it is leaving room for a navigation controller, without knowing that one is already there. How can I tell the TTThumbsViewController to use the existing uinavigationcontroller? Or behave as though it is? MYThumbsViewController *mYThumbsViewController = [MYThumbsViewController alloc]; [self.navigationController pushViewController:mYThumbsViewController animated:YES]; The problem depicted graphically: Thanks!

• BuildManager.CreateInstanceFromVirtualPath ignores compiled code

  - by Vnuk

  This question is related to http://stackoverflow.com/questions/2158425/why-cant-i-publish-mvc-project I've replaced System.Web.MVC with its source version. After some debugging I pinpointed my problem to line 50 of WebFormViewEngine.cs: protected override bool FileExists(ControllerContext controllerContext, string virtualPath) { try { object viewInstance = BuildManager.CreateInstanceFromVirtualPath(virtualPath, typeof(object)); return viewInstance != null; } For reasons unknown to me, BuildManager.CreateInstanceFromVirtualPath tries to find masterpage.aspx.vb file which does not exist because MVC application is published. What makes BuildManager.CreateInstanceFromVirtualPath behave this way, and how to debug? I've tried this with new blank MVC project. After publishing it and stopping at above location, BuildManager.CreateInstanceFromVirtualPath creates an instance without trying to compile anything.

• Validate signature on EXE with CertGetCertificateChain

  - by cobaia

  I would like to verify a signed executable. The requirement is to validate that the executable itself is valid and where it came from (probably from the subject of the cert). The cert type is PKCS. I found a similar posting here, http://stackoverflow.com/questions/301024/validate-authenticode-signature-on-exe-c-without-capicom The Microsoft documentation, among others, appears to point to CertGetCertificateChain, but the examples tend to work with certificates that are in a store. Does anyone know how to validate a signed executable using CertGetCertificateChain and related API's?

• ASP.NET MVC Html.ActionLink Maintains Route Values

  - by Carl

  Hi, I have a question that has pretty much been asked here: http://stackoverflow.com/questions/780643/asp-net-mvc-html-actionlink-keeping-route-value-i-dont-want However, the final solution is a kludge, pure and simple and I really would like to understand why this happens, if someone can please explain it to me? For completeness, it is possible to recreate the scenario very easily: Create a new MVC web app. Run it up. Visit the About tab Modify the URL to read /Home/About/Flib - This obviously takes you to the action with an id of 'Flib' which we don't care about. Notice that the top menu link to About now actually links to /Home/About/Flib - this is wrong as far as I can see, as I now have absolutely no way of using site links to get back to /Home/About I really don't understand why I should be forced to modify all of my Html.ActionLinks to include new { id = string.Empty } for the routevalues and null for the htmlAttribs. This seems especially out of whack because I already specify id = 0 as part of the route itself. Hopefully I'm missing a trick here.

  Hi, I know it's possible to have multiple languages in a single application through the res/string and depending on Locale. Here is a case http://stackoverflow.com/questions/2078289/android-controling-the-user-language Now how can I change the language in the phone ? Like I'd do by Menu Settings Language & Keyboard Select locale languages Is there some real code to access to these settings ? Or should I create intent for a shortcut to the language settings. Please post some code Edit : With Locale class developer.android.com/intl/fr/reference/java/util/Locale.html The constructor is at least Locale(String language) The input is language. How can you retrieve the current language used on the device ?

• Using FileReadFields with Wonderware

  - by hypoxide

  I suppose this is a long shot considering how few Wonderware questions I've seen on here, but anyway... The FileReadFields function in Wonderware is supposed to parse a CSV file into memory tags. There are no debug messages when stuff doesn't work in Wonderware (not my choice of HMI software, that's for sure), so I have no idea why this isn't working: FileReadFields("C:\NASA\Sample.csv", 0, Profile_Setup_Name, 1); Everything is cased correctly and the file is not in-use. I can't figure out how to make it work.

• Stretch and Scale a CSS image Background - With CSS only

  - by Fábio Antunes

  Good day. I always wanted to do this. I want that my background image stretch and scale depending the Browser view port size. I've seen some questions on SO that do the job, this One for example. Works well, but i want place the img in the background way, not with a image tag. In that one is placed a img tag, then with CSS we tribute to the img tag. width:100%; height:100%; It works, but that question is a bit old, and states that in CSS3 resizing a background image will work pretty well. I've tried this example the first one but i didn't workout for me. Does somebody know a good method to do it with the background image statement? If its sounds confusing just ask. Thanks

• "unbound identifier" errors in scheme

  - by user186909

  Hello: I'm using drscheme from: http://www.archlinux.org/packages/extra/x86_64/drscheme/ I'm trying to work with the sample code in my textbook, but I keep getting getting "unbound identifier" errors. Is it because the scheme interpreter is not configured correctly? or is the code just plain wrong? Here are a few examples: Input: #lang scheme (define (equalimp lis1 lis2) (COND ((NULL? lis1) (NULL? lis2)) ((NULL? lis2) '()) ((EQ? (CAR lis1) (CAR lis2)) (equalimp (CDR lis1) (CDR lis2))) (ELSE '()) )) Output: Welcome to DrScheme, version 4.2.5 [3m]. Language: scheme; memory limit: 128 MB. expand: unbound identifier in module in: COND Input: #lang scheme (define (quadratic_roots a b c) (LET ( (root_part_over_2a (/ (SQRT (- (* b b) (* 4 a c))) (* 2 a))) (minus_b_over_2a (/ (- 0 b) (* 2 a))) ) (DISPLAY (+ minus_b_over_2a root_part_over_2a)) (NEWLINE) (DISPLAY (- minus_b_over_2a root_part_over_2a)) )) Output: expand: unbound identifier in module in: LET Note: I tried using LET* because I read this: stackoverflow.com/ questions/946050/using-let-in-scheme but it produces the same error. Thanks !

• Linq where clause with multiple conditions and null check

  - by SocialAddict

  I'm trying to check if a date is not null in linq and if it isn't check its a past date. QuestionnaireRepo.FindAll(q => !q.ExpiredDate.HasValue || q.ExpiredDate >DateTime.Now).OrderByDescending(order => order.CreatedDate); I need the second check to only apply if the first is true. I am using a single repository pattern and FindAll accepted a where clause ANy ideas? There are lots of similar questions on here but not that give the answer, I'm very new to Linq as you may of guessed :) Edit: I get the results I require now but it will be checking the conditional on null values in some cases. Is this not a bad thing?

• android memory management outside heap

  - by Daniel Benedykt

  Hi I am working on an application for android and we since we have lots of graphics, we use a lot of memory. I monitor the memory heap size and its about 3-4 Mb , and peeks of 5Mb when I do something that requires more memory (and then goes back to 3). This is not a big deal, but some other stuff is handled outside the heap memory, like loading of drawables. For example if I run the ddms tool outside eclipse, and go to sysinfo, I see that my app is taking 20Mb on the Droid and 12 on the G1, but heap size are the same in both, because data is the same but images are different. So the questions are: How do I know what is taking the memory outside the heap memory? What other stuff takes memory outside the heap memory? Complex layouts (big tree) ? Animations? Thanks Daniel
