• MS CRM - getting the field that caused a form save

  - by CraigF

  I have a MS CRM 4 form where when certain fields are changed, I need those fields to be written to an excel sheet. So, I edited the form field onchange event to call crmform.save() which triggers a plugin to run that writes the field value to a named range (1 cell) of an excel sheet. However, I don't know which field caused the save. Is there a way to get that information? (Not all fields on the form need to go to the excel sheet) If I use this: DynamicEntity target = (DynamicEntity)Context.InputParameters[ParameterName.Target]; I can look at specific fields, but I have no way of knowing which ones changed. Any suggestions?

• Best way to optimize queries like this in Django

  - by chris

  I am trying to lower the amount of queries that my django app is using, but I am a little confused on how to do it. I would like to get a query set with one hit to the database and then filter items from that set. I have tried a couple of things, but I always get queries for each set. let's say I want to get all names from my DB, but also separate out the people just named Ted. Both the names and the ted set will be used in the template. This will give me two sets, one with all names and one with Ted.. but also hits the database twice: namelist = People.objects.all() tedList = namelist.filter(name='ted') Is there a way to filter the first set without hitting the data base again?

• how to specify the Build Engine Version when using VcBuild.exe on the command line.

  - by r9r9r9

  I create a c# class library project named: testVcBuild, then use vcbuild.exe to build the project in the command line like: C:\Program Files\Microsoft Visual Studio 9.0\VC\vcpackages>vcbuild testVcBuild.csproj "Debug|Win32" the out put shows: Microsoft (R) Visual C++ Project Builder - Command Line Version 9.00.21022 Copyright (C) Microsoft Corporation. All rights reserved. Microsoft (R) Build Engine Version 2.0.50727.4927 [Microsoft .NET Framework, Version 2.0.50727.4927] Copyright (C) Microsoft Corporation 2005. All rights reserved. I found that the vcbuild.exe always call the "C:\Windows\Microsoft.NET\Framework\v2.0.50727\Csc.exe /noconfig .." the problem is how can I change the Framework version to v3.5? I found my project works fine with the v3.5 but it's broken in the v2.0.50727. I try to use msbuild.exe instead of vcbuild.exe, everything goes well, I just don't understand how can I make it with the vcbuild.exe? win7+vs2005+vs2008 installed.

• How to make a DropDownList control display some items in bold ASP.Net

  - by james lewis

  I'm working with a custom DropDownList control in ASP.Net and there's been a request to display certain items in the list with a bold typeface (NOTE - the control inherits from CompositeDataBoundControl so it can be data bound... not DropDownListBox). The control is bound to a table and there's a column in the table named IsUsed - if this is set to true, the corresponding item in the list should be rendered bold. (It should be noted here that this will only ever be viewed in FireFox.) My experience is all in the middle \ backend tiers so the presentation layer is very new to me - can someone point me in the right direction? My initial thought was that somewhere in the custom control I would have access to all the rows that are returned from the data source which I could cycle through etc but I'm not sure if that's possible... There's also RenderContents which I can override... looks interesting! Any help appreciated - cheers. James

• myth about factory pattern

  - by leiz

  This has bothered me for awhile, and I have no clues if this is a myth. It seems that a factory pattern can ease the pain of adding a dependency for a class. For example, in a book, it has something like this Suppose that you have a class named Order. Initially it did not depend on anything. Therefore you didn't bother using a factory to create Order objects and you just used plain new to instantiate the objects. However, you now have a requirement that Order has to be created in association with a Customer. There are million places you need to change to add this extra parameter. If only you had de?ned a factory for the Order class, you would have met the new requirement without the same pain. How is this not same pain as adding an extra parameter to the constructor? I mean you would still need to provide an extra argument for the factory and that is also used by million places, right?

• how to better use of eclipse code templates (PHP)?

  - by pocketfullofcheese

  One particular problem I was having was using ${word_selection} in an Eclipse PDT template. I was recently trying to use some code templates with Eclipse PDT 2.1 to speed up some common tasks. We use a lot of getters/setters, so I wrote the following template. function get${word_selection}() { return $$this->getData('${word_selection}'); } function set${word_selection}($$${word_selection}) { $$this->setData('${word_selection}', $$${word_selection}); } I named the template "getset" and the only way I know to use the Code Assist is to type: "getset" then hit my code assist keys (I have it set to Esc, but I think the default was Ctrl+Space). The problem is, this doesn't actually let me select a word to be used by the ${word_selection}. how do I type in my template name, hit the key combo, and have a word selected all at the same time? I also want to know what kinds of templates people have set up and any other tips for using templates to speed of programming.

• Following PHP coding of Wisdom

  - by justjoe

  i read some wisdom like this : Programmers are encouraged to be careful when using by-reference variables since they can negatively affect the readability and maintainability of the code. i make my own solution, such as give suffix such as _ref in every by-reference variables. so, if i have a variable named as $files_in_root, then i will add suffix and changes it name into $files_in_root_ref. As far my knowledge goes, this is a good solution. So, here come the question Is there any best-practice on choosing suffix for by-reference variable in PHP coder world ? Or do you have any ? In general, how do we sustain readability and maintainability on PHP project with more then 3000 line of code ? I hope PHP coder world has unwritten aggrement for first question, cause it will help spot a pattern on any source code.

• slsvcutil.exe Proxy and Interfaces

  - by JPM

  Is it possible when using slsvcutil.exe to generate a proxy through the command line not to have the proxy file output the Interface in an Asynchronous fashion. For example, if I have a function "foo()" on the serverside in the Interface, when I generate the proxy using Slsvcutil.exe, it makes two functions in the interface definition in the proxy named "BeginFoo()" and "EndFoo()". All I want is "Foo()", I don't need the other two methods. Is this possible? I'm using the proxy with Monotouch which is why I need to use Slsvcutil.exe but don't need the Asynchronous methods. Thanks!

• Reading Stacktrace in Objective-C?

  - by yar

  I don't like real-time debugging much, but if it's necessary I'll do it. Is there any way to figure out what line of code a StackTrace in Objective-C refers to? What about the variable it refers to? For instance: 2010-05-13 19:39:11.673 Thingers[21003:207] *** -[NSCFString count]: unrecognized selector sent to instance 0x3b0ebb0 2010-05-13 19:39:11.674 Thingers[21003:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFString count]: unrecognized selector sent to instance 0x3b0ebb0' 2010-05-13 19:39:11.675 Thingers[21003:207] Stack: ( 29303899 ... 11130 ) I see that we're talking about sending a count message to something that doesn't have it (maybe it's a NSCFString?), but is there any way to figure out what a/the named reference to that instance (0x3b0ebb0) refers to?

• Internationalize HelloWorld program .NET

  - by RockStarInTraining

  I have small test app which has 2 resource files (Resources.resx & Resources.de-DE.resx) with the same exact string names, but one has the strings converted to German. For my form I set the Localize property to ture. In my application I am getting the strings as such: this.Text = Properties.Resources.frmCaption; In my release folder I get a de-DE folder with a dll named International_test.resources.dll. I try to distribute this to a machine which is set to German and all of the strings pulled are still english. I tried keeping the International_test.resources.dll in the de-DE folder or just put in in my apps directory. What am I doing wrong or what do I need to do to get the German resource file to be used?

• ActiveX controls with old Delphi versions

  - by DamienD

  I'm testing a non visual ActiveX control based on a registered .ocx which I import into Delphi using the provided wizard. Then, I simply put the generated component on the main form of a new VCL application. Under old Delphi versions (D5 and D2007), when i launch the application, this raise an AV during the component initialization. with Delphi 2009 : no problem, the application starts smoothly. My questions are : Are there known enhancements of ActiveX management in recent Delphi versions which can explain this difference ? Can I suspect a bug in the ActiveX control, or can I consider the origin of the problem is from old Delphi versions ? I need to use this component (if tests OK) in D2007. Do you think that it is possible to correct the AV problem under D2007 by modifying the D2007 generated .tlb file (for example by trying to use the D2009 generated one) PS: the ActiveX control is not named, because my question is a general question about Delphi and ActiveX, not about a specific ActiveX control.

• How can I retain carriage returns when I'm encrypting data?

  - by William Calleja

  I have this following setup, a textarea named with some data in it that may have carriage returns and another textarea that has style='display:none' in order to make it hidden as follows: <textarea id="myTextarea" onBlur="encryptMyData()"></textarea> <textarea name="encryptedText" style='display:none'></textarea> the user enters data in the first textarea and when that text area loses focus the 'encryptMyData()' javascript function is calling an ajax call to take whatever the user entered in the first textfield, encrypt it using rijndael, and paste it in the encryptedText textarea so that it is stored in the database later. Now what I need to do is this, find a way to convert the carriage returns before encryption to a tag like so [cr] so that when I retrieve the data, all formatting is retained. Any idea how I do this? I'm using asp.net and c# to perform the encryption.

• How can I make named_scope in Rails return one value instead of an array?

  - by sameera207

  I want to write a [named scope] to get a record from its id. For example, I have a model called Event, and I want to simulate Event.find(id) with use of named_scope for future flexibility. I used this code in my model: named_scope :from_id, lambda { |id| {:conditions => ['id= ?', id] } } and I call it from my controller like Event.from_id(id). But my problem is that it returns an array of Event objects instead of just one object. Thus if I want to get event name, I have to write event = Event.from_id(id) event[0].name while what I want is event = Event.from_id(id) event.name Am I doing something wrong here?

• Multiple Default Routes in ASP.NET MVC to different Default Actions

  - by Alex

  I have multiple controllers with different actions (no "Index" actions). The actions I consider "default" actions, are named differently. I want to create default routes for their names and have the first available action (from my list of default actions) executed if only the controller name is provided in the route. So, for example, I have the following actions which I want to consider default and want checked for their existence in a controller in this order: List() Draw() ViewSingle() The routing should somehow search for /{controller} and then take the first available action from the list above as default action, e.g.: /ControllerA -> ControllerA.List() /ControllerB -> ControllerB.Draw() /ControllerC -> ControllerC.ViewSingle() /ControllerD -> ControllerD.Draw() /ControllerE -> ControllerE.List() Is this possible? I tried creating additional Default actions like this but couldn't get it to work: routes.MapRoute("Default1", "{controller}/{action}", new { controller = UrlParameter.Optional, action = "List" } routes.MapRoute("Default2", "{controller}/{action}", new { controller = UrlParameter.Optional, action = "Draw" } routes.MapRoute("Default3", "{controller}/{action}", new { controller = UrlParameter.Optional, action = "ViewSingle" } Help?

• Single Page Navigation w/ Javascript and Back Button

  - by Khan

  Ok, so I have a "navigation" div and "content" div. When something on the navigation is clicked, I fade in the content div with the new data. Now, I would like to have the old data returned when the user hits the "back" button on his/her browser, but I'm having a hard time doing this. I know I can set the content to be a named anchor, so they stay on the same page with a breadcrumb trail. However, that's as far as I get. Can I listen for a back button click? Can I set content to display when a certain anchor name is reached? Thanks in advance for your help, SO.

• Custom UITableviewcell shows "fatal error: Can't unwrap Optional.None" issue in swift

  - by user1656286

  I need to load a custom cell in a UITableView. I created a custom subclass of UITableViewCell named "CustomTableViewCell". I have added a UITabelViewCell to the tableview (using drag and drop) as shown in figure. Then in file inspector I set the class of that UITabelViewCell to be "CustomTableViewCell". Here is my code: class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource { @IBOutlet var tableView : UITableView var items = String[]() override func viewDidLoad() { super.viewDidLoad() items = ["Hi","Hello","How"] self.tableView.registerClass(CustomTableViewCell.self, forCellReuseIdentifier: "CusTomCell") // Do any additional setup after loading the view, typically from a nib. } func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int{ return items.count } func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!{ var cell:CustomTableViewCell = self.tableView.dequeueReusableCellWithIdentifier("CusTomCell") as CustomTableViewCell cell.labelTitle.text = items[indexPath.row] return cell; } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } } When I run my code, I get the following error: "fatal error: Can't unwrap Optional.None" as seen in the image.
