• I need an algorithm to find the best path

  - by user242635

  I need an algorithm to find the best solution of a path finding problem. The problem can be stated as: At the starting point I can proceed along multiple different paths. At each step there are another multiple possible choices where to proceed. There are two operations possible at each step: A boundary condition that determine if a path is acceptable or not. A condition that determine if the path has reached the final destination and can be selected as the best one. At each step a number of paths can be eliminated, letting only the "good" paths to grow. I hope this sufficiently describes my problem, and also a possible brute force solution. My question is: is the brute force is the best/only solution to the problem, and I need some hint also about the best coding structure of the algorithm.

• .NET Propertygrid refresh trouble

  - by osss

  Property grid do not show new value of selected object. For example: o.val = "1"; pg.SelectedObject = o; o.val = "2"; pg.Refresh(); The property in property grid still "1"; It is changing only if click on this property.. or like that: o.val = "1"; pg.SelectedObject = o; o.val = "2"; pg.SelectedObject = o; but in this case focus will be changed to propertygrid.

• Is there a more efficient way to set variables on a RadioButton's CheckChanged event?

  - by C Patton

  I have 16 radio buttons in an application of mine.. I have to set a variable based on which one was selected.. and I've produced some very ugly code doing this.. private void Foo_CheckedChanged(object sender, EventArgs e) { convertSource = 1; } private void Bar_CheckedChanged(object sender, EventArgs e) { convertSource = 2; } private void Baz_RadioButton_CheckedChanged(object sender, EventArgs e) { convertSource = 3; } Now, I've been thinking about it and to be honest I thought there might have been a way to do it with a switch.. I just can't conceptualize it in my mind. If anyone could show me a more efficient way of doing this, I'd really appreciate it. It's just really bugging me that such a simple thing as this is taking up fifty to seventy lines of code. thanks, cpatton

• VB.NET WebBrowser control not navigating to a local document

  - by blerh

  I have this code set up to navigate to a certain .html document depending on what's selected from a ListBox: Private Sub FileList_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FileList.SelectedIndexChanged HelpWindow.Navigate(System.AppDomain.CurrentDomain.BaseDirectory & "help\" & fileArray(FileList.SelectedIndex, 1)) End Sub The problem is, when I first select something in the ListBox, it successfully navigates to that file and displays it. But when I select something a second time it doesn't change. All of the paths it's trying to navigate to are correct. I've checked this 1000 times. Anyone have any clues why this isn't working? Thank you.

• mouseover detection in NSTableView's NSCell?

  - by Wigwam

  I am wanting to change the text background color on a tableview's cell when it is hovered upon, similar to how AddressBook "highlights" the label of a contact's element when you mouseover the label names. However I cannot figure out how to accomplish... detecting a mouseover on a particular NSCell and... After detecting the cell his hovered upon, highlighting the text in that cell (not highlighting the entire row as if the user selected that row) As NSCell is not a subclass of NSView this seems to be a very difficult task. Any example of this or explanation on how this might be done would be greatly appreciated. Thanks!

• collapse jquery treeview plugin when focusing on another element

  - by Andy Simpson

  Hello all, Is there a way to have the jquery treeview plugin automatically collapse when a user focuses on another element. More detail about what I am trying to do: I have a form where a user has to select an item from a large selection. To make this easier I have set up a small list of 5 commonly selected items each with associated radio select buttons. However if the item wanted is not in this common list the user has to use the treeview to search through different categories to find the item. Is there a way to collapse the treeview when the user clicks on one of the radio buttons from the common item list? Thanks for your help in advance, Andy

• Process-wide hook using SetWindowsHookEx

  - by mfya

  I need to inject a dll into one or more external processes, from which I also want to intercept keybord events. That's why using SetWindowsHookEx with WH_KEYBOARD looks like an easy way to achieve both things in a single step. Now I really don't want to install a global hook when I'm only interested in a few selected processes, but Windows hooks seem to be either global or thread-only. My question is now how I would properly go about setting up a process-wide hook. I guess one way would be to set up the hook on the target process' main thread from my application, and then doing the same from inside my dll on DLL_PROCESS_ATTACH for all other running threads (plus on DLL_THREAD_ATTACH for threads started later). But is this really a good way? And more important, aren't there any simpler ways to setup process-wide hooks? My idea looks quite cumbersome und ugly, but I wasn't able to find any information about doing this anywhere.

• Can CultureInfo.CurrentCulture differ per application pool?

  - by Peter

  I'm having trouble with CultureInfo in our ASP.NET web application. Our web application returns a different culture, depending on which application pool it is in. In application pool A, it is en-US, but in application pool B, it's nl-BE. I'd like it to be nl-BE, but can't find where to change this (IIS6 by the way). I'm not even sure if this can be changed on an app-pool level. I'm checking with CultureInfo.CurrentCulture.Name. Is it possible to change this for an application pool? Or what else could influence this? In the regional settings of the server, we have selected 'Dutch (Belgium)', which translates to nl-BE, I believe. So where could this application pool be getting the en-US?

• How to edit localized forms all at one time in Visual Studio

  - by SoMoS

  Hello, I have several forms that are localized to multiple languages. If I do a change on one form (for example, changing the size of a textbox) the change is done only on the localized version of the Form that I have currently selected. Is there a way of extending the change I've done the different localized versions of the same Form to avoid having to go one by one doing the same change by hand? Thanks in advance for your help. EDIT: I'm talking about different forms when the real thign is that you have one form and several resources. The point is that at the end is just like if you have different forms for each locale because the form is built with the data from the resource. The problem is still the same because the edits done on the form are stored at one resource file and I have to put by hand those edits in all the resources.

• Java - JTable multiple instances

  - by Brian

  I have a JTable that gets data added to it from another JTable. Now I want to switch between JTables according to the day selected in a JComboBox. For example, if I choose Monday I add programs added to it then I select Tuesday from the JComboBox and a fresh JTable appears. If I go to Monday again the programs should still be there (until the program is closed). How do I create multiple JTables (the JTable remains the same) for the days and let the info remain there until program closure? Here is an example to show you what I mean:

• Cannot create class diagram for simple dll class in Visual Studio 2010

  - by xenn_33

  Hi, It seems that there is a really annoying issue in Class Diagram designer in VS (my version is 2010 Ultimate, but the issue is also observed in VS 2008). When I'm trying to create a class diagram for particular simple class from DLL I'm getting the following error: "Some of the selected type(s) cannot be added to the class diagram. Check the code for errors and ensure that all required assemblies ... blah-blah-blah" My code doesn't contain any error. I have multiple class and interface definitions in one separate .cs file, but these classes are really simple - even no calls to unmanaged/interop. Any solution for this?

• Custom date time picker for Windows Forms that is locked to GMT time

  - by m3ntat

  Using Visual Studio 2008, c#, .net 2.0. I have a Windows Forms client application that contains a scheduling UI section, currently this is housed only in the London office with the standard datetime picker control, the selected time is saved in a UK database (GMT) and a London based server aapplication processes the schedules. There is a requirement to roll the client out to various global locations, Hong Kong, New York etc and allow them to setup schedules that run according to GMT time on the London server. I'll have a label on screen saying "note schedules are GMT" what I need is a good way to present a datetime picker that always shows and is in sync with the database server's GMT time regardless of where the client app is running globally. Suggestions on how to acheive this? thanks.

• Make MySQL database replication always use the most free node?

  - by Chad Johnson

  We started using Multi-Master Replication Manager for MySQL, and I am wondering whether it is possible to to treat this setup like multi-symmetric processing: a process pops off the process queue, and the node (in this case a server) that is most free is selected for the job. It seems that what happens is, the service switches to a slave ONLY when it mysqld crashes or goes away. Is there a way to make database replication for MySQL act in more of a distributed manner? Maybe there is other software besides MMM that can do this? Is there a way to switch the reader role to another server whene mysqld slows down (rather than just when it fails)?

• Put text input inside label for radio button?

  - by Martijn

  I'm trying to make a radio group specifying a bunch of options, and an extra option "other" with a text input to specify. The code for this particular radio button I'm using is <input type='radio' name='RadioInput' value='Other' id='RadioInput_Other' /> <label for='RadioInput_Other'>Ohter: <input type='text' name='RadioInput_Other_Value' id='RadioInput_Other_Value' value='' /> </label> The idea is that if you give focus to the text input, the radio button corresponding to it is selected. The code above almost does this (since the text input is inside the label). However, it also shifts focus to the radio button (which is annoying, since whatever you type next is lost). Is there any way to prevent this using XHTML1.0 / CSS2? Preferably without using javascript.

• Lightweight jQuery ColorPicker bound to input and with popup selector

  - by Scott B

  I've found two jQuery colorpickers that I'm considering using in my app. I have a simple input field that I'm asking users to supply a hex color to. I'd like to use jPicker's "Binded" example, however, the overall size of the jPicker is a bit more than I'd like to add to my app. So that sent me searching and I found a very nifty little compact picker called "Farbtastic", which does exactly what I want with one major exception: It appears to be an inline only solution (meaning, I can't call it in the same manner as jPicker's binded example. Can someone tell me how I might convert Farbtastic to mimic jPicker's binded example? More specifically, I'm looking to place a colorpicker widget (the small color frame icon as in the jPicker example) next to my input field so that it displays the currently selected color, and when clicked, it opens up the color palette widget.

• Using plist to populate a grouped table

  - by Jack Griffiths

  Hi there, I was wanting to use a plist to populate my grouped table. I've had a look at the DrillDownSave sample project, and I'm still none-the-wiser. Although, I did learn that I could store hierarchies and suchlike in there. So here's the questions: How can I use my plist to add new items to my grouped table? I'm currently feeding the table with an array, and I've noticed that an array isn't going to be the best thing for me. When a user taps on an item in the plist, how can I push the view to the corresponding item? In other words, how can I push the view based on the selected row (which was generated by the plist) to it's next "view"? If that makes any sense, please reply. Thanks, Jack.

• my android app runs fine in the emulator, but when i publish it it's wrong

  - by Charlie

  i have an app that has a few checkboxes in the settings and then compiles a remote sql based on the checkboxes selected. i ran it in the emulator and it's fine. but then i exported it and published it as an app, and the same checked boxes aren't being passed correctly. i wonder if it's a caching issue or something. tried deleting the apks a few times and republish but to no avail. i "fake-edited" the source java and then export again, still no difference. i'm kind of new to eclipse but is there a force build option? i only see build-automatically option under project but not sure how i can make sure that the apk exported is the same as run in the emulator edit the emulator is version 1.5, and my phone is nexus one running 2.1- not sure if that makes a difference thanks

• Allowing threads from python after calling a blocking i/o code in a python extension generated using

  - by SS

  I have written a python extension wrapping an existing C++ library live555 (wrapping RTSP client interface to be specific) in SWIG. The extension works when it is operated in a single thread, but as soon as I call the event loop function of the library, python interpreter never gets the control back. So if I create a scheduled task using threading.Timer right before calling the event loop, that task never gets executed once event loop starts. To fix this issue, I added Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS macros manually in the SWIG auto generated wrapper cxx file around every doEventLoop() function call. But now, I want to do the same (i.e. allow threads) when SWIG generates the code itself and not to change any code manually. Has anyone done something similar in SWIG? P.S. - I would also consider switching to any other framework (like SIP) to get this working. I selected SWIG over any other technology is because writing SWIG interface was really very easy and I just had to include the existing header files.

• How to call an programmatically generated event for wxRadioButton in wxWidgets ?

  - by Jakub Czaplicki

  I am trying to programmatically change a value of a wxRadioButton in a way the user would do it. A value change doesn't call the event corresponded to the button, and it make sense since the documentation says it clearly: wxRadioButton::SetValue void SetValue(const bool value) Sets the radio button to selected or deselected status. This does not cause a wxEVT_COMMAND_RADIOBUTTON_SELECTED event to get emitted. So the question is how can I call an programmatically generated event for a wxRadioButton ? I guess that it's something to do with: wxWindow window->AddPendingEvent(wxEvent *event ) A simple example would be greatly appreciated.

• Optimal preferences for prefix queries with Oracle catalog (CTXCAT) index

  - by nw

  The documentation for Oracle Text gives this example of a prefix/substring preference setting for context and catalog indexes: begin ctx_ddl.create_preference('mywordlist', 'BASIC_WORDLIST'); ctx_ddl.set_attribute('mywordlist','PREFIX_INDEX','TRUE'); ctx_ddl.set_attribute('mywordlist','PREFIX_MIN_LENGTH', '3'); ctx_ddl.set_attribute('mywordlist','PREFIX_MAX_LENGTH', '4'); ctx_ddl.set_attribute('mywordlist','SUBSTRING_INDEX', 'YES'); end; What I need to know is whether the substring_index attribute is necessary if I only ever issue prefix searches, such as: SELECT title FROM auction WHERE CATSEARCH(title, 'cam*', '') > 0; TITLE --------------- CANON CAMERA FUJI CAMERA NIKON CAMERA OLYMPUS CAMERA PENTAX CAMERA SONY CAMERA 6 rows selected

• Android: Where to find the RadioButton Drawable?

  - by Peterdk

  Ok, I am trying to create a custom view called CheckedRelativeLayout. It's purpose is the same as a CheckedTextView, to be able to use it in a list of items you want selected or in a Spinner. It's all working fine now, I extended RelativeLayout and implemented Checkable interface. However, I am stuck on a quite simple problem: Where can I find the Drawable that CheckedTextView and RadioButton use? I looked at the sourcecode of both, and they seem to use com.android.internal.R. Well... that's internal stuff. So I can't access it. Any way to get these Drawables or solve the problem somehow?
