• Storing an image map in a database

  - by ColoradoRockie

  I have a requirement to allow users in a content management system to create their own image maps through a gui interface, which I have accomplished. But instead of saving the image map to the page code, I want to save the image map code to a database (sql), which I've also accomplished. When I started down this road in my head I was thinking the whole time that I'd just add the "usemap" attribute at runtime shown below where promo1.ImageMap holds the entire map code: if(promo1.HasImageMap) imgPromotion1.Attributes.Add("usemap", promo1.ImageMap); I guess I didn't think it though well enough, because it seems that "usemap" only expects the name of the existing map to use from the page code, and not the map code as a string. Does anyone have any clever ideas on how to apply the map from the database to the image at run time?

• How can I set the line style of a specific cell in a QTableView?

  - by Bob Nelson

  I am working with a QT GUI. I am implementing a simple hex edit control using a QTableView. My initial idea is to use a table with seventeen columns. Each row of the table will have 16 hex bytes and then an ASCII representation of that data in the seventeenth column. Ideally, I would like to edit/set the style of the seventeenth column to have no lines on the top and bottom of each cell to give the text a free flowing appearance. What is the best way to approach this using the QTableView?

• How to display the properties of a Scheduled Task?

  - by TooFat

  I have C# app that uses a Form to set a bunch of settings. Those settings can be read by a Console App so it can run via the built in Windows Task Scheduler. I would like to be able to simply open up a scheduled task as if I had just opened it from the gui in Windows so the user can set all the settings for the scheduled task. I know I can use a library like http://www.codeproject.com/KB/cs/tsnewlib.aspx but I would rather not have to recreate all the options in a WinForm when everything is already available in Windows. Does anyone know how I can programattically display the built in Windows Task Scheduler from C#?

• JUnit - stop it from exiting on finish?

  - by waitinforatrain

  Hi guys, Quick JUnit question. I'm running some unit tests that involve starting up the GUI and doing a load of stuff. I would like to see the results after the test to confirm it visually. However, it gets to the end of the code and exits, as it should. If I want to override this, I put a breakpoint on the last line of the test. This is pretty awkward though. Is there some option to stop it from exiting?

• wx Python is not properly drawing customtree items

  - by uberjumper

  Hi, I am currently using wx.CustomTree, to use to display a series of configuration settings. I generally fill them with wx.TextCtrl / wx.Combobox, to allow the user to edit / enter stuff. Here is my code: class ConfigTree(CT.CustomTreeCtrl): """ Holds all non gui drawing panel stuff """ def __init__(self, parent): CT.CustomTreeCtrl.__init__(self, parent, id = common.ID_CONTROL_SETTINGS, style = wx.TR_DEFAULT_STYLE | wx.TR_HAS_BUTTONS | wx.TR_HAS_VARIABLE_ROW_HEIGHT | wx.TR_SINGLE) #self.HideWindows() #self.RefreshSubtree(self.root) self.population_size_ctrl = None self.SetSizeHints(350, common.FRAME_SIZE[1]) self.root = self.AddRoot("Configuration Settings") child = self.AppendItem(self.root, "Foo", wnd=wx.TextCtrl(self, wx.ID_ANY, "Lots Of Muffins")) The problem is, any children nodes, the data for these nodes is not filled in. When i basically expand the configuration settings tree node. I see the "Foo" node, however the textbox is empty. This is the same for both text node, Until i actually click on the child node. I've looked tried every form of update / etc. Does anyone have any ideas?

• Why do we use HTTP and not remote invocations?

  - by BrokenClockwork

  Hey, first of all this is a conceptional question and I do not know if StackOverflow is the appropriate place - so my apologies if I am wrong. Nowadays the web is not only used for passing raw informations. Many and especially complex web applications are in use. These web application seem to be so complex that it seems irrational to use the HTTP protocol, which is based on so simple data exchange, plus it is stateless. Would it not be more convincing to use remote invocations for this web applications? The big advantage to my mind is a unified GUI by using HTML. But there are applications, which have no need for a graphical interfaces and then it comes to a point where the HTTP protocol is really cumbersome.

• Use case modelling for calculator

  - by kyrogue

  hi, i need help modelling a use case diagram from a topic, it will be in java GUI Design a Calculator that 1.Allow user to key in a legitimate arithmetic statement that involves number, operator +, - and bracket '(' and ')' ; 2.When user press “Calculate” button, display result; 3.Some legitimate statement would be ((3+2)-4+2) (equals 3) and (-2+3)-(3-1) (equals -1); 4.You should NOT use a pre-existing function that just take in the statement as a parameter and returns the result but you should write the logic of parsing every character in your code. 5.Store the last statement and answer so it is displayed when user press the “Last calculation” button. i have designed two use case diagrams using UML on netbeans 6.5.1, one of the use case i am not sure whether is it containing too much use cases etc, while the other is what i think could be too vague for the topic.i hope to get some feedback on whether the use case diagram are appropriate, thanks.

• Visual Studio Pre build events and batch set

  - by helloworld922

  Hi, I'm trying to create call a batch file which sets a bunch of environment variables prior to building. The batch file looks something like this (it's automatically generated before-hand to detect ATI Stream SDK or NVidia CUDA toolkit): set OCL_LIBS_X86="%ATISTREAMSDKROOT%libs\x86" set OCL_LIBS_X64="%ATISTREAMSDKROOT%libs\x86_64" set OCL_INCLUDE="%ATISTREAMSDKROOT%include" However, the rest of the build doesn't seem to have access to these variables, so when I try to reference $(OCL_INCLUDE) in the C/C++GeneralAdditional include directories, it will first give me warning that environment variable $(OCL_INCLUDE) was not found, and when I try to include CL/cl.hpp the compile will fail with: fatal error C1083: Cannot open include file: 'CL/cl.hpp': No such file or directory I know that I could put these variables into the registry if I wanted to access them from the visual studio GUI, but I would really prefer not to do this. Is there a way to to get these environment variables to stick after the pre-build events? I can't reference $(ATISTREAMSDKROOT) directly because the project must be able to build for both ATI Stream and NVidia Cuda.

• installing windows service with SC.exe or InstallUtil.exe - there is difference but which?

  - by LosManos

  hejdig. SC.exe and InstallUtil both install/uninstall windows services. But they don't seem to work the same way. What is the difference? For instance InstallUtil fails (some file or dependency not found error) while Sc create happily installs the service. Too add to the strangeness; the service doesn't show up if I run net start in the console. But it does show up in the services GUI. Variants of this happen when I try to uninstall. I have written the service myself and earlier versions work. Dotnet3.5. /OF

• What is the difference between building a WSDL in Eclipse and using WCF?

  - by myermian

  I'm somewhat familiar with WCF in that I can build Web Services in VS.Net ... I understand some of the concepts... But, the other day I cam across this option in Eclipse (I also use Java to code) to create a WSDL. Playing around with it it looks great since it has a GUI method of building itself. I guess I just wanna know what the difference is. 1) Are they different technologies like WSDL vs WCF? Or, is it that WCF uses WSDLs? 2) I read that WSDLs are a top-down approach... so what about WCF, is that top-down or is that bottom-up? 3) Will this WSDL in Eclipse actually be able to generate CSharp code for my server and client efficiently, or will it require a lot of fixing?

• Async Socket Listener on separate thread - VB.net

  - by TheHockeyGeek

  I am trying to use the code from Microsoft for an Async Socket connection. It appears the listener runs in the main thread locking the GUI. I am new at both socket connections and multi-threading all at the same time. Having a hard time getting my mind wrapped around this all at once. The code used is at http://msdn.microsoft.com/en-us/library/fx6588te.aspx Using this example, how can I move the listener to its own thread? Public Shared Sub Main() ' Data buffer for incoming data. Dim bytes() As Byte = New [Byte](1023) {} ' Establish the local endpoint for the socket. Dim ipHostInfo As IPHostEntry = Dns.GetHostEntry(Dns.GetHostName()) Dim ipAddress As IPAddress = ipHostInfo.AddressList(1) Dim localEndPoint As New IPEndPoint(ipAddress, 11000) ' Create a TCP/IP socket. Dim listener As New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp) ' Bind the socket to the local endpoint and listen for incoming connections. listener.Bind(localEndPoint) listener.Listen(100)

• Can you use Github App with Beanstalk?

  - by mikemick

  Being new to Git, I wanted to use a GUI (Windows based) and preferred the Github App. However, I would like to integrate this site with a Beanstalkapp account. I'm pretty sure this is possible, but I can't figure it out. Inside of the Github app, I navigate to my repository. When I choose "Tools Settings...", I place the Git Clone URL for the repository provided by Beanstalk into the "Primary Remote (origin)" field in my Github app. Now when I click "Publish" (which says "Click to publish this branch to server" when I hover over it) it changes to "Publishing...". After a few seconds, I get this error: server failure The remote server disconnected. Try again later, or if this persists, contact [email protected] I am pretty sure I set the SSH keys up properly (never done this before). I added the key to both the Beanstalkapp and my Github web account.

• Office Interop addins installer?

  - by jimbojw

  I have three C# Solutions in Visual Stuido 2008, one each for Word, Excel and PowerPoint using interop to hook various events. In each Solution, I have exactly one class, the one created by default when using File - New - Project - Visual C# - Office - 2007. Now that I have my addins working properly, it's time to create an installer. I understand that I may also have to distribute the PIAs. I would like my installer to register itself such that it can be uninstalled via the normal Add/Remove Programs mechanism. My organization is somewhat standardized around WiX for creating installers, but I'm open to any suggestions. How do I produce an MSI or EXE capable of installing my addins? GUI/wizard for the installer is not necessary. I'm happy to RTFM - so far all the tutorials I've found only explain how to create the project and do some of the coding. Maybe I'm using the wrong search terms? Thanks in advance for any help!

• How can I receive CameraActivities result in a DIFFERENT Activity (i.e. not in the launching one)?

  - by steff

  Hi, I hope the title says it all: I've got Activity A which fires up the Camera intent via: Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(intent, REQUEST_CAMERA); After the picture is taken I can easily grab the picture in: @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) But I'd like to receive the result in Activity B in which the image can be edited. Right now I'm receiving the result in Activity A and pass it over to Activity B which results in showing the GUI of Activity A for a short while: Intent i = new Intent().setAction("DisplayJPEG"); i.setClass(this, EditImageActivity.class); i.putExtra("IMAGE_URI", uri); startActivityForResult(i, REQUEST_EDIT_IMAGE); Of course, I will need the result from Activity B in Activity A after the image has been edited. But that should work with: setResult(resultCode, data); So there has to be a way to do what I need. Please point me into the right direction. Thanks in advance, steff

• 0xDEADBEEF equivalent for 64-bit development?

  - by Peter Mortensen

  For C++ development for 32-bit systems (be it Linux, Mac OS or Windows, PowerPC or x86) I have initialised pointers that would otherwise be undefined (e.g. they can not immediately get a proper value) like so: int *pInt = reinterpret_cast<int *>(0xDEADBEEF); (To save typing and being DRY the right-hand side would normally be in a constant, e.g. BAD_PTR.) If pInt is dereferenced before it gets a proper value then it will crash immediately on most systems (instead of crashing much later when some memory is overwritten or going into a very long loop). Of course the behavior is dependent on the underlying hardware (getting a 4 byte integer from the odd address 0xDEADBEEF from a user process may be perfectly valid), but the crashing has been 100% reliable for all the systems I have developed for so far (Mac OS 68xxx, Mac OS PowerPC, Linux Redhat Pentium, Windows GUI Pentium, Windows console Pentium). For instance on PowerPC it is illegal (bus fault) to fetch a 4 byte integer from an odd address. What is a good value for this on 64-bit systems?

• Creating a "netbeans property" style dialog box

  - by pikco

  Hi I've been trying to create a GUI using netbeans, that includes a dialog similar to Netbean's own "property dialog" that appears when designing. ie. a dialog that contains a table that can be expanded by tree nodes. Something like the dialog on this page, http://platform.netbeans.org/tutorials/nbm-property-editors.html As far as I can understand, the page I linked to describes a custom editor I can set up for use within netbeans while designing - I'm just looking for a way to doing something similar for my actual application I'm writing. Is there an easy way to do this? I came across this and have tried it but it doesn't quite work in the same way as the standard Netbeans dialog. weblogs.java.net/blog/timboudreau/archive/2008/06/egads_an_actual.html Any tips greatly appreciated.

• Silverlight DRY when animating multiple UserControls on main Navigation page.

  - by Tobias op den Brouw

  Hello all. Starting with Silverlight development. Yet to read a good Silverlight book: suggestions welcome. I have a main GUI screen where 7 user controls (menu items) 'swoop' into sight, all along their own path. I have the user controls nicely seperated and behaving well. Having multiple storyboards (1 each for each menuitem) with multiple keyframe animations (X,Y,height, width) in one .XAML is not sitting well with me. Repeating all those property values is hideous, neverthemind maintenance. I've tried to move values into the app.xaml and set animation durations with style keys, but having limited success. Can anyone suggest a nice way of making this cleaner? Refactor the storyboards out to their own control? Property values in resources? Dynamic building in codebehind? Referring me to a how-to site is fine as well. Tx!

• Tough question on WPF, Win32, MFC

  - by Mack

  Let's suppose you're an IT student with a basic knowledge of C++ and C#. Let's suppose that you want to design apps that: need to deliver some performance like archivers, cryptographic algorithms, codecs make use of some system calls have a gui and you want to learn an Api that will enable you to write apps like those described earlier and: is mainstream is future proof entitles you to find a decent job is easy enough - I mean easy like VCL, not easy like winapi So, making these assumptions, what Api will you choose? MFC, WPF, other? I really like VCL and QT, but they're not mainstream and I think few employers will want you to write apps in QT or Visual C++ Builder... Thanks for answers.

• Sandcastle setup - Navigation to webpage was canceled.

  - by Prof Plum

  I am try to use Sandcastle Help File Builder, but can't quite get it to work. Here is what I have done: 1) installed the program; works like normal 2) enabled xml in the project I want documentation for that gets generated in the /bin 3) created a new sandcastle help file project 4) added the C# project as (its a WCF service in case that matters) a documentation service 5) ran the "build" to generate the help file 6) went to "documentation"/"view help file"/"view help file" in the GUI 7) The file opens and contains the appopriate "folders", but every page says "Navigation to the webpage was canceled" I have seen the xml file in the /bin and it contains all of my /// comments, so why are they not showing up in the help file? Any ideas?

• What is the difference between MVC model 1 and model 2?

  - by Alex Ciminian

  I've recently discovered that MVC is supposed to have two different flavors, model one and model two. I'm supposed to give a presentation on MVC1 and I was instructed that "it's not the web based version, that is refered to as MVC2". As the presentations are about design patterns in general, I doubt that this separation is related to Java (I found some info on Sun's site, but it seemed far off) or ASP. I have a pretty good understanding of what MVC is and I've used several (web) frameworks that enforce it, but this terminology is new to me. How is the web-based version different from other MVC (I'm guessing GUI) implementations? Does it have something to do with the stateless nature of HTTP? Thanks, Alex

• What is the easiest way to reference libraries in Qt projects?

  - by Jake Petroules

  I have two Qt4 Gui Application projects and one shared library project, all referenced under a .pro file with the "subdirs" template. So, it's like: exampleapp.pro app1.pro app2.pro sharedlib.pro Now, what I want to do is reference sharedlib from app1 and app2 so that every time I run app1.exe, I don't have to manually copy sharedlib.dll from its own folder to app1.exe's folder. I could set PATH environment variable in the projects window, but this isn't very portable. I've looked at putting the LIBS variable in the app1.pro file, but I'm not sure if that refers to statically linked libraries only - I've tried it with various syntaxes and it doesn't seem to work with shared libs.

• What should I call a class that contains a sequence of states

  - by Robert P

  I have a GUI tool that manages state sequences. One component is a class that contains a set of states, your typical DFA state machine. For now, I'll call this a StateSet. However, I have another class that has a collection (possibly partially unordered) of those state sets, and lists them in a particular order. and I'm trying to come up with a good name for it - not just for internal code, but for customers to refer to it. I've got: Sequence (maybe) StateSetSet (reasonable for code, but not for customers) Any other suggestions or ideas?

• Getting progress status out of a class library method

  - by Richard

  This app that I am doing uses a class library (if I dare call it that) to do the bulk of the work: 2 main methods in there (DoWork and UndoWork) use the other classes to achieve thier goal. Now that that works, I want to get out of the Console test enviroment and do a GUI. How would I get the status of say, the DoWork() method to update a progress bar? Should I multilate the class library (which currently works with the Console and Windows.Forms) to update? The problem with that is that I would surely have to make the class library use Window.Forms which will mess up the console testing apps (And there are lots of them - I tested all the way through, and then all together). Could you suggest some ideas, or places I can read up about ideas (the whole point of writing this this program is to learn, afer all)? Oh, by the way, suggestions like "foresight" or "planning" probably won't help here...(now, anywyay!) - But certainly will in future projects!

• Visual Editor vs Manual code

  - by Albinoswordfish

  I'm not sure how it is using other frameworks but this questions is strictly regarding Java swing. Is it better to use a Visual Editor to place objects or to manually code the placement of the objects onto the frame (Layout managers or null layouts)? From my experience I've had a lot of trouble using Visual editors when it comes to different screen resolutions or changing the window size. Using manual code to place objects I've found that my GUIs behave a lot better with regard to the screen size issue. However when I want to change a small part of my GUI it takes a lot more work compared to using a visual editor Just wondering what people's thoughts were on this?

  I'm trying to write a script the generates a template file for Pashua (a perl script for creating GUI on osx) I want to crate an instance for each item in the array, so the ideal output would be: AB1.type = openbrowser AB1.label = Choose a master playlist file AB1.width=310 AB1.tooltip = Blabla filesystem browser AB2.type = openbrowser AB2.label = Choose a master playlist file AB2.width=310 AB2.tooltip = Blabla filesystem browser ...and so on for the rest of the array: What I am using to write to the text file at the moment is: count=1 saveIFS="$IFS" IFS=$'\n' array=($(<TEST.txt)) IFS="$saveIFS" for i in "${array[@]}"; do declare AD$count="$i"; ((count++)); done for i in "${array[@]}"; do echo "AD$count".type = openbrowser "AD$count".label = Choose a master playlist file \n "AD$count".width=310 \n "AD$count".tooltip = Blabla filesystem browser \n" >> long.txt; done However \n doesn't produce a newline in the text file, and I am pretty sure there is a alot nicer way todo this, ideas?
