• Trying to create a RegEx for the following patterns

  - by Travis

  Here are the patterns: Red,Green (and so on...) Red (+5.00),Green (+6.00) (and so on...) Red (+5.00,+10.00),Green (+6.00,+20.00) (and so on...) Red (+5.00),Green (and so on...) Each attribute ("Red,"Green") can have 0, 1, or 2 modifiers (shown as "+5.00,+10.00", etc.). I need to capture each of the attributes and their modifiers as a single string (i.e. "Red (+5.00,+10.00)", "Green (+6.00,+20.00)". Help?

  - by Eike Cochu

  to capture keystrokes for registering global hotkeys i want to use the shortcut recorder. but i can't get it to work. here is what i have done so far: checked out the current version from the svn installed xcode 3 because my xcode 4 wouldn't build, then built it with xcode 3 in xcode 4, i added the shortcutrecorder.framework in the build-directory to my application, dragged/copied the SRRecorderControl.h to my application directory and inserted #import "SRRecorderControl.h" to my AppDelegate.h when i build and run, it fails and says images not found. i know that there are images in the shortcut recorder main directory, but i dont know where to put these. and: how do i add the special shortcut recorder textfield to my main window?

• penetration of web 2.0 features amongst users?

  - by user151841

  I have a survey web-app that is public facing. I want to set up automated testing with Selenium, but selenium can't capture javascript alerts that we're currently using on the site. I'm thinking about changing our user-facing error notifications to some web 2.0 javascript library so that it is accessible to Selenium. However, I'm not sure how many of our users would be able to experience them properly. How backwards-compatible do I need to be in the present day? I have collected a database of actual user-agent strings of our users. I asked here how I could group them into meaningful data about what browsers our users are actually using.

• How can I validate input to the edit control of a cell in a DataGridView?

  - by Stuart Helwig

  It appears that the only way to capture the keypress events within a cell of a DataGridView control, in order to validate user input as they type, is to us the DataGridView controls OnEditControlShowing event, hook up a method to the edit control's (e.Control) keypress event and do some validation. My problem is that I've built a heap of custom DataGridView column classes, with their own custom cell types. These cells have their own custom edit controls (things like DateTimePickers, and Numeric or Currency textboxes.) I want to do some numeric validation for those cells that have Numeric of Currency Textboxes as their edit controls but not all the other cell types. How can I determine, within the DataGridView's "OnEditControlShowing" override, whether or not a particular edit control needs some numeric validation?

• How to add a Tooltip to a "td" with jquery?

  - by Scott

  I need to add a tooltip/alt to a "td" element inside of my tables with jquery. Can someone help me out? I tried: var tTip ="Hello world"; $(this).attr("onmouseover", tip(tTip)); where I have verified that I am using the "td" as "this". Edit:I am able to capture the "td" element through using the "alert" command and it worked. So for some reason the "tip" function doesn't work. Anyone know why this would be?

• Best canvas for drawing in wxPython?

  - by Pablo Rodriguez

  I have to draw a graph of elements composing a topological model of a physical network. There would be nodes and arches, and the latter could be unidirectional or bidirectional. I would like to capture the clicking events for the nodes and the arches (to select the element and show its properties somewhere), and the dragging events for the nodes (to move them around) and arches (to connect or disconnect elements). I've done some research and I've narrowed the alternatives down to OGL (Object Graphics Library) and FloatCanvas. I would not like to go down to the DrawingContext, but it is not discarded if necessary. Which canvas option would you choose?

• Showing custom model validation exceptions in the Django admin site.

  - by Guy Bowden

  I have a booking model that needs to check if the item being booked out is available. I would like to have the logic behind figuring out if the item is available centralised so that no matter where I save the instance this code validates that it can be saved. At the moment I have this code in a custom save function of my model class: def save(self): if self.is_available(): # my custom check availability function super(MyObj, self).save() else: # this is the bit I'm stuck with.. raise forms.ValidationError('Item already booked for those dates') This works fine - the error is raised if the item is unavailable, and my item is not saved. I can capture the exception from my front end form code, but what about the Django admin site? How can I get my exception to be displayed like any other validation error in the admin site?

  Hello, I am trying to build a release version of my project. Our prof made us create a static library which i built using debug version. then i made a release version of that static library using /mt as my c runtime now in my test application (release version) I use the same runtime option and add that static library and also ignore the libcmd.lib in the ignore settings for the linker. i resolved most of the problem this is the last part lnk4075 /edit and continue due to /opt:icf specification compositelib.lib (my staticlib) lnk2001 unresolved external symbol _winmain@16. libcmtd.lib these are the last two that i can't seem to figure out.

• How do I know if a drag/drop has been cancelled in WPF

  - by Jon Mitchell

  I'm writing a user control in WPF which is based on a ListBox. One of the main pieces of functionality is the ability to reorder the list by dragging the items around. When a user drags an item I change the items Opacity to 50% and physically move the item in an ObservableCollection in my ViewModel depending on where the user wants it. On the drop event I change the Opacity back to 100%. The problem I've got is that if the user drags the item off my control and drops it somewhere else then I need to change the Opacity back to 100% and move the item back to where it was when the user started the drag. Is there an event I can handle to capture this action? If not is there any other cunning way to solve this problem?

• Making Django ignore string literals

  - by James

  UPDATE: It turns out this is a deeper question than I thought at first glance - the issue is that python is replacing the string literals before they ever get to django. I will do more investigating and update this if I find a solution. I'm using django to work with LaTeX templates for report generation, and am running into a lot of problems with the way Django replaces parts of strings. Specficially, I've run into two problems where I try to insert a variable containing latex code. The first was that it would replace HTML characters, such as the less than symbol, with their HTML codes, which are of course gibberish to a LaTeX interpreter. I fixed this by setting the context to never autoescape, like so: c = Context(inputs) c.autoescape = False However, I still have my second issue, which is that Django replaces string literals with their corresponding characers, so a double backslash becomes \, and \b becomes a backspace. How can I force Django to leave these characters in place, so inputs['variable'] = '{\bf this is code} \\' won't get mangled when I use {{variable}} to reference it in the django template?

• Ruby on Rails- :symbols, @iVars and "strings" - oh my!

  - by Meltemi

  New to Rails and trying to get my head around when/why to use :symbols, @ivars , "strings" within the framework. I think I understand the differences between them conceptually only one :symbol instance per project one @ivar per instance multiple "strings" - as they are created whenever referenced (?) Feel free to correct me! The main confusion comes from understanding the rules & conventions of what Rails expects - where and WHY? I'm sure there's an "Ah ha!" moment coming but I haven't had it yet...as it seems pretty arbitrary to me (coming from C/Obj-C). -thx

• How do I include 3rd party libraries in my code...

  - by Krakkos

  I understand the process of using a 3rd party library to access functions outside of my code base, but how do i actually set up Visual Studio 2005 to include them in the project. I have a 3rd party library with some headers, some cpp's, and some .lib files. In the projects properties I add the top level external library directory as an include directory, I add the additional library directory at the same level put this is project properties too. In the .cpp file where I use the functions, do I put the #include in its header file? In the top level projects header file? in the cpp? I've tried all that, but I get "unresolved external symbol"... grrrrrrrrrrrrr

• How to execute ant using java and captured the output?

  - by Iso

  Hi, I have an ant build file that contains JUnit test suite that I would like to execute. Currently I just right click and run the build file from Eclipse. I want to write a java code that can execute the ant build file automatically. So I just run the code and ant will be executed. Second is I want to capture the test result. Currently the result is based on JUnit HTML report. I want to make my own simple test report. I read there is JUnitResultFormatter but I can't find the instructional step by step how to use it. Can anyone point me the reference? Thanks in advance.

• Transient variables are not captured properly on form submission

  - by Kalpana

  My User entity class have several member variables (e.g. String firstName) which are persisted and some transient variables (e.g. transient boolean selected) which are not. I have used the transient variable to capture a checkbox selection, but invariably the value never gets set and procesed properly until I set another bean value along with it. i.e. If User has firstName (mapped to a text field) and selected (mapped to a checkbox) If I just selected the value doesn't seem to be set on an update If I had selected the checkbox and the firstName field, the "selected" value is captured properly Can anyone tell me why this is happening?

• the breakpoint will not currently be hit no symbols loaded

  - by Carlos_Liu

  I want to debug on the customer's machine (Windows Server 2003) to track a problem, and out product is based on .NET 2.0. I want to use DbgCLR.exe to debug a file AAA.dll, what I did is: install .NET 2.0 SDK on the customer's machine (to get the DbgCLR.exe) copy the symbol file AAA.pdb to the same directory with AAA.dll get the source file for AAA.dll the AAA.dll will be loaded by w3wp.exe, so in the DbgCLR Tools-Attach to Process, then I choose w3wp.exe File-Open-File open the source file and add a breakpoint in the function which will be callled but the breakpoint seems do no work because there is an warning icon on it and says : the breakpoint will not currently be hit. No symbols have been loaded for this document. On my computer (Windows XP) which has the debug version of whole source code, I did nearly the same thing as above but the different is: I attached aspnet_wp.exe to do the debug and it works What should I do to let it work on the customer's machine?

• Does Postgresql varchar count using unicode character length or ASCII character length?

  - by bennylope

  I tried importing a database dump from a SQL file and the insert failed when inserting the string Mér into a field defined as varying(3). I didn't capture the exact error, but it pointed to that specific value with the constraint of varying(3). Given that I considered this unimportant to what I was doing at the time, I just changed the value to Mer, it worked, and I moved on. Is a varying field with its limit taking into account length of the byte string? What really boggles my mind is that this was dumped from another PostgreSQL database. So it doesn't make sense how a constraint could allow the value to be written initially.

• Retain Delimiters when Splitting String

  - by JoeC

  Edit: OK, I can't read, thanks to Col. Shrapnel for the help. If anyone comes here looking for the same thing to be answered... print_r(preg_split('/([\!|\?|\.|\!\?])/', $string, null, PREG_SPLIT_DELIM_CAPTURE)); Is there any way to split a string on a set of delimiters, and retain the position and character(s) of the delimiter after the split? For example, using delimiters of ! ? . !? turning this: $string = 'Hello. A question? How strange! Maybe even surreal!? Who knows.'; into this array('Hello', '.', 'A question', '?', 'How strange', '!', 'Maybe even surreal', '!?', 'Who knows', '.'); Currently I'm trying to use print_r(preg_split('/([\!|\?|\.|\!\?])/', $string)); to capture the delimiters as a subpattern, but I'm not having much luck.

• Handling null values with PowerShell dates

  - by Tim Ferrill

  I'm working on a module to pull data from Oracle into a PowerShell data table, so I can automate some analysis and perform various actions based on the results. Everything seems to be working, and I'm casting columns into specific types based on the column type in Oracle. The problem I'm having has to do with null dates. I can't seem to find a good way to capture that a date column in Oracle has a null value. Is there any way to cast a [datetime] as null or empty?

• gdb + nasm debug info not being created

  - by cpowel2

  I am relatively new to assembly language programming and am trying to debug a small .asm file that I wrote in Ubuntu. I am however running into an issue where my symbol table is not being loaded and was looking for some help. I am compiling my program as follows. nasm -f elf -g -F dwarf bs.asm gcc -m32 -g bs.o -o bs which produces the executable bs when I run gdb bs I get a message that says no debugging symbols and when I try to set a break point by b main it says function not defined even though its in the file and I can run it using ./bs I read a couple posts that suggested adding the -F dwarf when assembling but that didn't help if anyone has any insight I would greatly appreciated your input. Thanks in advance

• Why is it so hard to build a gtk programe without console using cmake in windows?

  - by Runner

  I'm following the tuto: http://zetcode.com/tutorials/gtktutorial/firstprograms/ It works but each time I double click on the executable,there is a console which I don't want it there. How do I get rid of that console? I tried this: add_executable(Cmd WIN32 cmd.c) But got this fatal error: MSVCRTD.lib(crtexew.obj) : error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup Cmd.exe : fatal error LNK1120: 1 unresolved externals While using gcc directly works: gcc -o Cmd cmd.c -mwindows .. I'm guessing it has something to do with the entry function: int main( int argc, char *argv[]),but why gcc works? How can I make it work with cmake?

• Google Gears hangs when capturing (unmanaged resource store)

  - by Gus

  Our code was written based on the example from Google Gears' own docs. We're using an unmanaged resource store. So we declare the files in an array, create the store, and capture all the files. Trouble is, the capturing process hangs. It always hangs on a random file (no discernible pattern has emerged), and when you reload the page, it always successfully captures. We're capturing 48 files. It seems to have nothing to do with the files themselves, as it hangs on every file type. I've seen it hang on the 6th file or the 47th. Windows and Mac. FF, IE, and Safari. We are not using a WorkerPool, and I'm thinking this may be necessary. Any other ideas why it would hang?
