  • RichTextBox doesn't update caret position correctly

    - by shadeMe
    I have a handler consuming the keyDown event of a WinForms RTB, that has the following code: GetTextAtLoc(RTB->SelectionStart); // selects some text at the caret's position RTB->SelectedText = "SomeOfMyOwn"; GetTextAtLoc(RTB->SelectionStart); // selects the replacement string RTB->SelectionStart += RTB->SelectionLength - 1; While this code seems to do its job (SelectionStart/Length properties are updated correctly), the caret doesn't move to the end of the new string - It says right where it was at the time of GetTextAtLoc's first call. Redrawing the textbox does seem to have any effect either.

  • get_or_create generic relations in Django & python debugging in general

    - by rabidpebble
    I ran the code to create the generically related objects from this demo: http://www.djangoproject.com/documentation/models/generic_relations/ Everything is good intially: >>> bacon.tags.create(tag="fatty") <TaggedItem: fatty> >>> tag, newtag = bacon.tags.get_or_create(tag="fatty") >>> tag <TaggedItem: fatty> >>> newtag False But then the use case that I'm interested in for my app: >>> tag, newtag = bacon.tags.get_or_create(tag="wholesome") Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/lib/python2.6/dist-packages/django/db/models/manager.py", line 123, in get_or_create return self.get_query_set().get_or_create(**kwargs) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 343, in get_or_create raise e IntegrityError: app_taggeditem.content_type_id may not be NULL I tried a bunch of random things after looking at other code: >>> tag, newtag = bacon.tags.get_or_create(tag="wholesome", content_type=TaggedItem) ValueError: Cannot assign "<class 'generics.app.models.TaggedItem'>": "TaggedItem.content_type" must be a "ContentType" instance. or: >>> tag, newtag = bacon.tags.get_or_create(tag="wholesome", content_type=TaggedItem.content_type) InterfaceError: Error binding parameter 3 - probably unsupported type. etc. I'm sure somebody can give me the correct syntax, but the real problem here is that I have no idea what is going on. I have developed in strongly typed languages for over ten years (x86 assembly, C++ and C#) but am new to Python. I find it really difficult to follow what is going on in Python when things like this break. In the languages I mentioned previously it's fairly straightforward to figure things like this out -- check the method signature and check your parameters. Looking at the Django documentation for half an hour left me just as lost. Looking at the source for get_or_create(self, **kwargs) didn't help either since there is no method signature and the code appears very generic. A next step would be to debug the method and try to figure out what is happening, but this seems a bit extreme... I seem to be missing some fundamental operating principle here... what is it? How do I resolve issues like this on my own in the future?

  • how to specify the file path in rails over Mongrel web server

    - by erwin
    hi, I have a request to load a swf file, flaMovie.swf from rails. The swf file is located the directory /home/user1/railsproj/flash. I have the code index.rhtml under view directory to show the .swf file, ID=flaMovie WIDTH=250 HEIGHT=250 When I ran the code, I got the error, ActionController::RoutingError (No route matches "/home/user1/railsproj/flash/flaMovie.swf" with {:method=:get}): /vendor/rails/actionpack/lib/action_controller/routing.rb:1441:in recognize_path' /vendor/rails/actionpack/lib/action_controller/routing.rb:1424:inrecognize' /vendor/rails/actionpack/lib/action_controller/dispatcher.rb:170:in handle_request' /vendor/rails/actionpack/lib/action_controller/dispatcher.rb:115:indispatch' /vendor/rails/actionpack/lib/action_controller/dispatcher.rb:126:in dispatch_cgi' /vendor/rails/actionpack/lib/action_controller/dispatcher.rb:9:indispatch' /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/rails.rb:76:in process' /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/rails.rb:74:insynchronize' My rails project is located in /home/user1/railsproj and the web server is Mongrel web server.

  • How do I set the bake command to use a different template in cakephp

    - by Gaurav Sharma
    Hi all, I wanted bake command to bake a view of my liking. So I searched bakery and found this Modify-default-HTML-produced-by-baked-templates. But after reading this I was not able to modify the template because I wanted to define some CSS in it and those files are not containing any CSS code (they contain only php code inside them). Also if I have designed my own CSS file for the new template then how do I tell bake command to pick that specified css file for new template ? I am totally confused over here. Has anybody done this similar kinda work using cakePHP. Any help would be greatly appreciable. NOTE: I am using cakePHP v 1.3 latest stable release. Thanks

  • Java static and thread safety or what to do

    - by Parhs
    I am extending a library to do some work for me. Here is the code: public static synchronized String decompile(String source, int flags,UintMap properties,Map<String,String> namesMap) { Decompiler.namesMap=namesMap; String decompiled=decompile(source,flags,properties); Decompiler.namesMap=null; return decompiled; } The problem is that namesMap is static variable. Is that thread safe or not? Because if this code runs concurently namesMap variable may change. What can I do for this?

  • Having trouble getting MEF imports to be resolved

    - by Dave
    This is sort of a continuation of one of my earlier posts, which involves the resolving of modules in my WPF application. This question is specifically related to the effect of interdependencies of modules and the method of constructing those modules (i.e. via MEF or through new) on MEF's ability to resolve relationships. First of all, here is a simple UML diagram of my test application: I have tried two approaches: left approach: the App implements IError right approach: the App has a member that implements IError Left approach My code behind looked like this (just the MEF-related stuff): // app.cs [Export(typeof(IError))] public partial class Window1 : Window, IError { [Import] public CandyCo.Shared.LibraryInterfaces.IPlugin Plugin { get; set; } [Export] public CandyCo.Shared.LibraryInterfaces.ICandySettings Settings { get; set; } private ICandySettings Settings; public Window1() { // I create the preferences here with new, instead of using MEF. I wonder // if that's my whole problem? If I use MEF, and want to have parameters // going to the constructor, then do I have to [Export] a POCO (i.e. string)? Settings = new CandySettings( "Settings", @"c:\settings.xml"); var catalog = new DirectoryCatalog( "."); var container = new CompositionContainer( catalog); try { container.ComposeParts( this); } catch( CompositionException ex) { foreach( CompositionError e in ex.Errors) { string description = e.Description; string details = e.Exception.Message; } throw; } } } // plugin.cs [Export(typeof(IPlugin))] public class Plugin : IPlugin { [Import] public CandyCo.Shared.LibraryInterfaces.ICandySettings CandySettings { get; set; } [Import] public CandyCo.Shared.LibraryInterfaces.IError ErrorInterface { get; set; } [ImportingConstructor] public Plugin( ICandySettings candy_settings, IError error_interface) { CandySettings = candy_settings; ErrorInterface = error_interface; } } // candysettings.cs [Export(typeof(ICandySettings))] public class CandySettings : ICandySettings { ... } Right-side approach Basically the same as the left-side approach, except that I created a class that inherits from IError in the same assembly as Window1. I then used an [Import] to try to get MEF to resolve that for me. Can anyone explain how the two ways I have approached MEF here are flawed? I have been in the dark for so long that instead of reading about MEF and trying different suggestions, I've added MEF to my solution and am stepping into the code. The part where it looks like it fails is when it calls partManager.GetSavedImport(). For some reason, the importCache is null, which I don't understand. All the way up to this point, it's been looking at the part (Window1) and trying to resolve two imported interfaces -- IError and IPlugin. I would have expected it to enter code that looks at other assemblies in the same executable folder, and then check it for exports so that it knows how to resolve the imports...

  • Miss a single tap randomly

    - by pion
    I have the following code snippets - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; NSUInteger numberTaps = [touch tapCount]; // Tapping if (numberTaps > 0) { // do something } ... The above code basically detects a single tap on a small image (width = 18 and height = 36). It works 90% of the time detecting a single tap. But it sometime misses it (randomly). I have to tap several times before it picks up the single tap. What did I do wrong or miss so I could consistently detect the single tap 100%? Thanks in advance for your help.

  • NamedParameterJdbcTemplate jconnect decimal issue

    - by user1052849
    I am using NamedParameterJdbcTemplate to insert data into a table. (Spring 2.5.3/Java 1.6) I am using jconnect driver to connect to sybase jdbc:sybase:Tds:<Server>:<Port>. For some reason the decimal values the decimal part is truncated. With the same code if I use jtds driver (jdbc:jtds:sybase://<Servername>:<Port>) its working fine. I cannot use jtds as jconn is being used by other code. In Java objects, field is defined as double. In database, field is defined as float (numeric with precision does not work). Any help is appreciated.

  • C# differences between Windows Mobile and regular Windows

    - by Matt
    Are there many differences between Windows and Windows Mobile as far as C# programming is concerned? I can write some moderately complicated programs in C#, but I'm not sure if it would just run perfectly on a Windows smartphone, or if something has to be done to port it. If so, is there a tool that will automatically revise code to make it mobile-compatible? The reason I ask is that the new Windows mobile 7 will only support a few methods of app development, one of which is C#. Also, do smartphones with non-windows operating systems have C# support available? Or can C# code be converted to Symbian or iPhone or whatever? Thanks for any help you can provide.

  • How to use parameter with LIKE in Sql Server Compact Edition

    - by Colin
    I'm trying to parameterise a search query that uses the LIKE keyword with a wildcard. The original sql has dynamic sql like this: "AND JOB_POSTCODE LIKE '" + isPostCode + "%' " So I've tried this instead, but I get a FormatException: "AND JOB_POSTCODE LIKE @postcode + '%' " Edit: I guess the FormatException isn't going to be coming from Sql Server CE, so as requested, here is how I set the parameter in my C# code. The parameter is set in code like this: command.Parameters.Add("@postcode", SqlDbType.NVarChar).Value = isPostCode; I also tried: "AND JOB_POSTCODE LIKE @postcode" with command.Parameters.Add("@postcode", SqlDbType.NVarChar).Value = isPostCode + "%"; but that doesn't return any results. Can anyone advise how to use parameters in this search sql?

  • How to subclass a specific jqueryui widget method ?

    - by SBUJOLD
    Since I updated jQueryUI to 1.8 I found a couple of issues in our implementations and I could fix it myself without waiting for a fix on their end if I could find out how to subclass a specific method of the datepicker widget so I call the parent code and then execute my code. I was reading on $.widget but I just can't wrap my head around how that is suppose to work. I tried something like this: $.widget("ui.datepicker", { _showDatepicker: function(input) { alert('Yo'); $.datepicker.prototype._showDatepicker.apply(this,arguments); alert('Hey!'); } }); And all sorts of other variations and beging to think I just don't understand the 'extendability' of jQueryUI or it just can't be done. Anybody knows how I can achieve this ? Thx

  • Only perform jquery effects/operations on certain pages

    - by Galen
    Up until now i've been dropping all my jquery code right inside the document.ready function. I'm thinking that for certain situations this isnt the best way to go. for example: If i want an animation to perform when a certain page loads what is the best way to go about that. $(document).ready(function() { $("#element_1").fadeIn(); $("#element_2").delay('100').fadeIn(); $("#element_3").delay('200').fadeIn(); }); If this is right inside of document.ready then every time ANY page loads it's going to check each line and look for that element. What is the best way to tell jquery to only perform a chunk of code on a certain page to avoid this issue.

  • Using Yii framework, what would be a right way to process an attribute before displaying it using CH

    - by Karolis
    Say I have this line of code in the view. <?php echo CHtml::activeTextField($model,'start_time'); ?> start_time is a UNIX timestamp. When just displaying it in a view I can apply functions like date() on it. Where should I apply the formatting when I'm displaying it in a form, by using the above line of code? (This case of timestamps/dates might be special, but I'm also interested in how would one go about if it wasn't a date and I just want to work with "value in database" < "different representations of the value in different views. Thanks =)

  • Ending php sessions for debugging purposes

    - by Bill Zimmerman
    Hi, This might be very easy to do, but I haven't been able to figure it out. Basically, I have a loosely couple web-app written in python and php. The python code uses PHP sessions (generated from the PHP app when the user logs in) to check if the user is logged in/has permission to access the given python resource. My question is this: What is the easiest way to force all active sessions to timeout. I would like to do this for debugging purposes, to test out the python code. I tried changing the session.max_lifetime PHP variable, but that still doesn't guarantee that the session has ended and is removed. I tried just deleting the file, but this seems to cause problems (when i refresh the php page, errors show up in my apache logs and it won't reload quickly) Any ideas?

  • Best way for programmers to edit XAML

    - by JessicaB
    I was wondering how programmers chose to edit XAML. Most of the programmers I speak to seem to edit the raw XML, but that seems nuts to me since it is such a natural thing for a more visual editor (of course you often have to get down to the raw code ultimately, but isn't there a better way to lay out a grid, or edit a template, or add non c# triggers or manage commands? The one that really set me off was editing a menu -- Visual Studio 1.0 had a better menu editor for C++ than the raw XAML editing experience.) When I edit .aspx files I use a visual editor much of the time, and then for the raw stuff I get into the html code. I am aware of Expression Blend, but that seems far more focused on artistic types and GUI experts rather than programmers. Does anyone have recommendations for a better editor for XAML than VS? Especially so since VS seems to have real nasty problems with XAML editing too, like bugginess and poor performance? Appreciate your helping this XAML newbie.

  • Automating Visual Studio 2010 from a console app

    - by JoelFan
    I am trying to run the following code (which I got from here). The code just creates a new "Output" pane in Visual Studio and writes a few lines to it. Public Sub WriteToMyNewPane() Dim win As Window = _ DTE.Windows.Item(EnvDTE.Constants.vsWindowKindOutput) Dim ow As OutputWindow = win.Object Dim owPane As OutputWindowPane Dim cnt As Integer = ow.OutputWindowPanes.Count owPane = ow.OutputWindowPanes.Add("My New Output Pane") owPane.Activate() owPane.OutputString("My text1" & vbCrLf) owPane.OutputString("My text2" & vbCrLf) owPane.OutputString("My text3" & vbCrLf) End Sub Instead of running it as a Macro, I want to run it as an independent console application that connects to a currently running instance of Visual Studio 2010. I'm having a hard time figuring out how to set the value of DTE. I think I may need to call GetActiveObject, but I'm not sure how. Any pointers?

  • Convert from Price

    - by Leroy Jenkins
    Im attempting to Convert a Price (from an API (code below)). public class Price { public Price(); public Price(double data); public Price(double data, int decimalPadding); } What I would like to do is compare the price from this API to a Double. Simply trying to convert to Double isnt working as I would have hoped. Double bar = 21.75; if (Convert.ToDouble(apiFoo.Value) >= bar) { //code } when I try something like this, I believe it says the value must be lower than infinity. How can I convert this price so they can be compared?

  • InvalidAttributeValueException when using non-ascii characters in JNDI

    - by matdan
    Hi, I have some trouble using JNDI since it accepts only 7-bits encoded parameters. I am trying to change an LDAP entry using JNDI with the following code : Attribute newattr = new BasicAttribute("userpassword", password); ModificationItem[] mods = new ModificationItem[1]; mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, newattr); context.modifyAttributes("uid=anID,ou=People,o=MyOrganisation,c=com", mods); If my password contains only ascii characters, it works perfectly, but if I use a non-ascii character, like "à", I have this error message : javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 19 - The value is not 7-bit clean: à]; My ldap supports those characters so I guess it comes from JNDI. Does anyone know how to fix that? Am I supposed to convert my parameter? How can I do that easily? Thanks

  • Redirect and parse in realtime stdout of an long running process in vb.net

    - by Richard
    Hello there, This code executes "handbrakecli" (a command line application) and places the output into a string: Dim p As Process = New Process p.StartInfo.FileName = "handbrakecli" p.StartInfo.Arguments = "-i [source] -o [destination]" p.StartInfo.UseShellExecute = False p.StartInfo.RedirectStandardOutput = True p.Start Dim output As String = p.StandardOutput.ReadToEnd p.WaitForExit The problem is that this can take up to 20 minutes to complete during which nothing will be reported back to the user. Once it's completed, they'll see all the output from the application which includes progress details. Not very useful. Therefore I'm trying to find a sample that shows the best way to: Start an external application (hidden) Monitor its output periodically as it displays information about it's progress (so I can extract this and present a nice percentage bar to the user) Determine when the external application has finished (so I can't continue with my own applications execution) Kill the external application if necessary and detect when this has happened (so that if the user hits "cancel", I get take the appropriate steps) Does anyone have any recommended code snippets?

  • How do I bring Set Focus of MDI Child Window using UIAutomation

    - by Scott Ferguson
    We have an old legacy application we need to automate. It uses MDI Windows. We're using UIAutomation and I can succesfully get the appropriate AutomationElement for each MDI Child window. What I cannot do is bring that element into focus. Here is some example code that I tried, that fails: var desktop = AutomationElement.RootElement; var dolphin = desktop.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Dolphin for Windows", PropertyConditionFlags.IgnoreCase)); dolphin.SetFocus(); var workspace = dolphin.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Workspace", PropertyConditionFlags.None)); var childWindow = workspace.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Sharp ")); childWindow.SetFocus(); The last line in this code fails with System.InvalidOperationException Experimenting, I tried finding a control on the childWindow, and calling SetFocus on it. It DID correctly set the focus on the right control, but it did not bring the MDI window to the foreground. Any ideas?
